    To develop a Consumer Quality Index (CQI) Cancer Care questionnaire for measuring experiences with hospital care of patients with different types of cancer. We derived quality aspects from focus group discussions, existing questionnaires and literature. We developed an experience questionnaire and sent it to 1,498 Dutch cancer patients. Another questionnaire measuring the importance of the quality aspects was sent to 600 cancer patients. Data were psychometrically analysed. The response to the experience questionnaire was 50 percent. Psychometric analysis revealed 12 reliable scales. Patients rated rapid and adequate referral, rapid start of the treatment after diagnosis, enough information and confidence in the healthcare professionals as most important themes. Hospitals received high scores for skills and cooperation of healthcare professionals and a patient-centered approach by doctors; and low scores for psychosocial guidance and information at completion of the treatment. The CQI Cancer Care questionnaire is a valuable tool for the evaluation of the quality of cancer care from the patient's perspective. Large scale implementation is necessary to determine the discriminatory powers of the questionnaire and may enable healthcare providers to improve the quality of cancer care. Preliminary results indicate that hospitals could improve their psychosocial guidance and information provision.

    Large, longitudinal surveys often lack consistent dietary data, limiting the use of existing tools and methods that are available to measure diet quality. This study describes a method that was used to develop a simple index for ranking individuals according to their diet quality in a longitudinal study. The RESIDential Environments (RESIDE) project (2004–2011) collected dietary data in varying detail, across four time points. The most detailed dietary data were collected using a 24-item questionnaire at the final time point (n = 555; age ≥ 25 years). At preceding time points, sub-sets of the 24 items were collected. A RESIDE dietary guideline index (RDGI) that was based on the 24-items was developed to assess diet quality in relation to the Australian Dietary Guidelines. The RDGI scores were regressed on the longitudinal sub-sets of six and nine questionnaire items at T4, from which two simple index scores (S-RDGI1 and S-RDGI2) were predicted. The S-RDGI1 and S-RDGI2 showed reasonable agreement with the RDGI (Spearman’s rho = 0.78 and 0.84; gross misclassification = 1.8%; correct classification = 64.9% and 69.7%; and, Cohen’s weighted kappa = 0.58 and 0.64, respectively). For all of the indices, higher diet quality was associated with being female, undertaking moderate to high amounts of physical activity, not smoking, and self-reported health. The S-RDGI1 and S-RDGI2 explained 62% and 73% of the variation in RDGI scores, demonstrating that a large proportion of the variability in diet quality scores can be captured using a relatively small sub-set of questionnaire items. The methods described in this study can be applied elsewhere, in situations where limited dietary data are available, to generate a sample-specific score for ranking individuals according to diet quality.

    Quality of life is an important patient-oriented measure in COPD. The Clinical COPD Questionnaire (CCQ) is a validated instrument for estimating quality of life. The impact of different factors on the CCQ-score remains an understudied area. The aim of this study was to investigate the association of co-morbidity and body mass index with quality of life measured by CCQ. A patient questionnaire including the CCQ and a review of records were used. A total of 1548 COPD patients in central Sweden were randomly selected. Complete data were collected for 919 patients, 639 from primary health care and 280 from hospital clinics. Multiple linear regression with adjustment for sex, age, level of education, smoking habits and level of care was performed. Subanalyses included additional adjustment for lung function in the subgroup (n = 475) where spirometry data were available. Higher mean CCQ score indicating lower quality of life was statistically significant and independently associated with heart disease (adjusted regression coefficient (95%CI) 0.26; 0.06 to 0.47), depression (0.50; 0.23 to 0.76) and underweight (0.58; 0.29 to 0.87). Depression and underweight were associated with higher scores in all CCQ subdomains. Further adjustment for lung function in the subgroup with this measure resulted in statistically significant and independent associations with CCQ for heart disease, depression, obesity and underweight. The CCQ identified that heart disease, depression and underweight are independently associated with lower health-related quality of life in COPD.

    Translation and cross-cultural adaptation of the instrument Hearing Implant Sound Quality Index (HISQUI19), and characterization of the target population and auditory performance in Cochlear Implant (CI) users through the application of a synthesis version of this tool. Evaluations of conceptual, item, semantic and operational equivalences were performed. The synthesis version was applied as a pre-test to 33 individuals, whose final results characterized the final sample and performance of the questionnaire. The results were analyzed statistically. The final translation (FT) was back-translated and compared with the original version, revealing a minimum difference between items. The changes observed between the FT and the synthesis version were characterized by the application of simplified vocabulary used on a daily basis. For the pre-test, the average score of the interviewees was 90.2, and a high level of reliability was achieved (0.83). The translation and cross-cultural adaptation of the HISQUI19 questionnaire showed suitability for conceptual, item, semantic and operational equivalences. For the sample characterization, the sound quality was classified as good with better performance for the categories of location and distinction of sound/voices.

    The Skin Cancer Index (SCI) is the first specific patient-reported outcome measure for patients with cervicofacial nonmelanoma skin cancer. To date, only the original English version has been published. To develop a Spanish version of the SCI that is semantically and linguistically equivalent to the original, and to evaluate its measurement properties in this different cultural environment. A cross-sectional study was conducted of the cultural adaptation and empirical validation of the questionnaire, analysing the psychometric properties of the new index at different stages. Of 440 patients recruited to the study, 431 (95%) completed the Spanish version of the SCI questionnaire, in a mean time of 6·3 min (SD 2·9). Factor analysis of the scale revealed commonality and loading values of < 0·5 for three of the 15 items. The remaining 12 items converged into two components: appearance/social aspects (seven items) and emotional aspects (five items). Both domains presented a high level of internal consistency, with Cronbach's alpha values above 0·8. The convergent-discriminant validity analysis produced correlations higher than 0·3 for the mental component of the Short Form Health Survey-12v2 Health Questionnaire (correlation coefficient 0·39) and the Dermatology Quality of Life Index (correlation coefficient -0·30). In the test-retest, nine of the 12 items produced a weighted kappa value exceeding 0·4, and for the remaining three items, the absolute agreement percentage exceeded 60%. The Spanish version of the SCI quality of life scale has been satisfactorily adapted and validated for use in Spanish-speaking countries and populations. © 2014 British Association of Dermatologists.

    Dysphagia can have severe consequences for the patient's health, influencing health-related quality of life (HRQoL). Sound psychometric properties of HRQoL questionnaires are a precondition for assessing the impact of dysphagia, the focus of this study, resulting in recommendations for the appropriate use of these questionnaires in both clinical practice and research contexts. We performed a systematic review starting with a search for and retrieval of all full-text articles on the development of HRQoL questionnaires related to oropharyngeal dysphagia and/or their psychometric validation from the electronic databases PubMed and Embase published up to June 2011. Psychometric properties were judged according to quality criteria proposed for health status questionnaires. Eight questionnaires were included in this study. Four are aimed solely at HRQoL in oropharyngeal dysphagia: the deglutition handicap index (DHI), dysphagia handicap index (DHI'), M.D. Anderson Dysphagia Inventory (MDADI), and SWAL-QOL, while the EDGQ, EORTC QLQ-STO 22, EORTC QLQ-OG 25 and EORTC QLQ-H&N35 focus on other primary diseases resulting in dysphagia. The psychometric properties of the DHI, DHI', MDADI, and SWAL-QOL were evaluated. For appropriate applicability of HRQoL questionnaires, strong scores on the psychometric criteria face validity, criterion validity, and interpretability are prerequisites. The SWAL-QOL has the strongest ratings for these criteria, while the DHI' is the most easy to apply given its 25 items and the use of a uniform scoring format. For optimal use of HRQoL questionnaires in diverse settings, it is necessary to combine psychometric and utility approaches.

    Accounting for patients' perspective has become increasingly important. Based on the Consumer Quality Index method (founded on Consumer Assessment of Healthcare Providers and Systems) a questionnaire was recently developed for Dutch cancer patients. As a next step, this study aimed to adapt and pilot this questionnaire for international comparison of cancer patients experience and satisfaction with care in six European countries. The Consumer Quality Index was translated into the local language at the participating pilot sites using cross-translation. A minimum of 100 patients per site were surveyed through convenience sampling. Data from seven pilot sites in six countries was collected through an online and paper-based survey. Internal consistency was tested by calculating Cronbach's alpha and validity by means of cognitive interviews. Demographic factors were compared as possible influencing factors. A total of 698 patients from six European countries filled the questionnaire. Cronbach's alpha was good or satisfactory in 8 out of 10 categories. Patient satisfaction significantly differed between the countries. We observed no difference in patient satisfaction for age, gender, education, and tumor type, but satisfaction was significantly higher in patients with a higher level of activation. This European Cancer Consumer Quality Index(ECCQI) showed promising scores on internal consistency (reliability) and a good internal validity. The ECCQI is to our knowledge the first to measure and compare experiences and satisfaction of cancer patients on an international level, it may enable healthcare providers to improve the quality of cancer care.

    Evaluation of quality of life has become a frequently used method in treatment effects supervision. Quality of Life Childhood Epilepsy (QOLCE) questionnaire, which is completed by patients' parents, has been prepared for children with epilepsy. It enables to determine the quality of life in children aged 4-18 years. The aim of the study was to show the usefulness of QOLCE questionnaire in evaluating the quality of life of children with epilepsy. 160 epileptic children, aged 8-18 years and their parents were examined in the Chair and Department of Developmental Neurology, K. Marcinkowski University of Medical Sciences in Poznań. QOLCE questionnaire was completed by parents and "Young people and epilepsy" questionnaire was designed for children. Reliability index of the complete questionnaire in own research and in the original amounted to 0.93 Cronbach alpha coefficient. Epileptic, drug-resistant children constituted 28% of the examined group. Parents of children with controlled seizures evaluated children's functioning in analyzed areas of quality of life higher. 1. QOLCE questionnaire is a suitable tool to evaluate the quality of children's and adolescents' life. 2. The most significant differences in functioning of epileptic, drug-resistant patients and those with controlled seizures were observed in areas of cognitive processes and social activity.

    Previous studies have evaluated quality of life (QoL) in patients who underwent laparoscopic cholecystectomy (LC) for cholelithiasis. The purpose of this study was to evaluate QoL after index admission LC in patients diagnosed with acute cholecystitis (AC) using the Gastrointestinal Quality of Life Index (GIQLI) questionnaire. Patients ≥21 years admitted to Tan Tock Seng Hospital, Singapore for AC and who underwent index admission LC between February 2015 and January 2016 were evaluated using the GIQLI questionnaire preoperatively and 30 days postoperatively. A total of 51 patients (26 males, 25 females) with a mean age of 60 years (24-86 years) were included. Median duration of abdominal pain at presentation was 2 days (1-21 days). 45% of patients had existing comorbidities, with diabetes mellitus being most common (33%). 31% were classified as mild AC, 59% as moderate and 10% as severe AC according to Tokyo Guideline 2013 (TG13) criteria. Post-operative complications were observed in 8 patients, including retained common bile duct stone (n=1), wound infection (n=2), bile leakage (n=2), intra-abdominal collection (n=1) and atrial fibrillation (n=2). 86% patients were well at 30 days follow-up and were discharged. A significant improvement in GIQLI score was observed postoperatively, with mean total GIQLI score increasing from 106.0±16.9 (101.7-112.1) to 120.4±18.0 (114.8-125.9) ( p <0.001). Significant improvements were also observed in GIQLI subgroups of gastrointestinal symptoms, physical status, emotional status and social function status. Index admission LC restores QoL in patients with AC as measured by GIQLI questionnaire.

    A questionnaire ('Dutch Musculoskeletal Questionnaire', DMQ) for the analysis of musculoskeletal workload and associated potential hazardous working conditions as well as musculoskeletal symptoms in worker populations is described and its qualities are explored using a database of 1575 workers in various occupations who completed the questionnaire. The 63 questions on musculoskeletal workload and associated potentially hazardous working conditions can be categorized into seven indices (force, dynamic and static load, repetitive load, climatic factors, vibration and ergonomic environmental factors). Together with four separate questions on standing, sitting, walking and uncomfortable postures, the indices constitute a brief overview of the main findings on musculoskeletal workload and associated potentially hazardous working conditions. Homogeneity of the indices is satisfactory. The divergent validity of the indices is fair when compared with an index of psychosocial working conditions and discomfort during exposure to physical loads. Worker groups with contrasting musculoskeletal loads can be differentiated on the basis of the indices and other factors. With respect to the concurrent validity, it appears that most indices and factors show significant associations with low back and/or neck-shoulder symptoms. This questionnaire can be used as a simple and quick inventory for occupational health services to identify worker groups in which a more thorough ergonomic analysis is indicated.

    Accounting for the patients' perspective on quality of care has become increasingly important in the development of Evidence Based Medicine as well as in governmental policies. In the Netherlands the Consumer Quality (CQ) Index has been developed to measure the quality of care from the patients' perspective in different healthcare sectors in a standardized manner. Although the scientific accountability of anthroposophic healthcare as a form of integrative medicine is growing, patient experiences with anthroposophic healthcare have not been measured systematically. In addition, the specific anthroposophic aspects are not measured by means of existing CQ Indexes. To enable accountability of quality of the anthroposophic healthcare from the patients' perspective the aim of this study is the construction and validation of a CQ Index for anthroposophic healthcare. Construction in three phases: Phase 1. Determining anthroposophic quality aspects: literature study and focus groups. Phase 2. Adding new questions and validating the new questionnaire. Research population: random sample from 7910 patients of 22 anthroposophic GPs. survey, mixed mode by means of the Dillman method. Measuring instrument: experience questionnaire: CQ Index General Practice (56 items), added with 27 new anthroposophic items added and an item-importance questionnaire (anthroposophic items only).

    The purpose of this study was to evaluate validity and reliability of a new proposed questionnaire for assessment of functional disability in athletes with low back pain (LBP). Validity and reliability study. Elite athletes participating in different fields of sports. Participants were 165 male and female athletes (between 12 and 50 years old) with LBP. Athlete Disability Index (ADI) Questionnaire which is developed by the authors for assessing LBP-related disability in athletes, Oswestry Disability Index (ODI), and the Roland-Morris Disability Questionnaire (RDQ). Self-reported responses were collected regarding LBP-related disability through ADI, ODI, and RDQ. The test-retest reliability was strong, and intraclass correlation value ranged between 0.74 and 0.94. The Cronbach alpha coefficient value of 0.91 (P < 0.001) demonstrated excellent internal consistency of the questionnaire. The correlation coefficient between ADI and ODI was r = 0.918 (P < 0.0001), between ADI and RDQ was r = 0.669 (P < 0.0001), and between ADI and visual analog scale was r = 0.626 (P < 0.001). According to ODI and RDQ, disability levels were mild in the large majority of subjects (91.5% and 86.0%, respectively). Alternatively, disability assessments by the ADI did not cluster at the mild level and ranged more broadly from mild to very high. The ADI is a reliable and valid instrument for assessing disability in athletes with LBP. Compared with the available LBP disability questionnaires used in the general population, ADI can more precisely stratify the disability levels of athletes due to LBP.

    To develop a Consumer Quality Index (CQ-index) Breast Care instrument that measures quality of care from the perspective of patients with (suspicion of) breast cancer. To develop a pilot questionnaire, three focus group discussions with breast cancer patients were performed. The questionnaire was sent to 1197 patients. We performed psychometric and descriptive analyses to optimise the new instrument. Focus group discussions revealed nine main themes related to breast care quality. Psychometric analyses resulted in 15 reliable scales. The final instrument consisted of 152 items, of which 118 items regarded patients' experiences. The aspect with the highest need for quality improvement was informing patients about a second opinion. The CQ-index Breast Care (CQI-BC) instrument provides a good starting point for further research on the quality of breast care seen from the perspective of patients. The newly developed instrument can be used by different stakeholders for future quality monitoring.

    The evaluation of health related quality of life (HRQOL) is essential for a full assessment of the influence of an illness on patients' lives. The aim of this paper is to critically appraise and compare the measurement properties of HRQOL questionnaires studied in haemophilia. Bibliographic databases (Embase, Medline, Cinahl and PsycInfo) were searched for articles evaluating measurement properties of HRQOL questionnaires in haemophilia. Articles were excluded that did not report HRQOL measurement properties, or when <50% of the study population had haemophilia. The methodological quality of the selected studies was evaluated using the COSMIN checklist. The measurement properties of the HRQL questionnaires were rated as 'positive', 'indeterminate' or 'negative', accompanied by levels of evidence. The search resulted in 1597 unique hits, of which 22 studies were included. These articles evaluated three questionnaires for children (CHO-KLAT, Haemo-QoL and one unnamed measure) and five for adults (Hemofilia-QoL, Haemophilia Well-Being Index, HAEMO-QoL-A, Haem-A-QoL, and SF-36). The CHO-KLAT was the paediatric measure that showed the strongest measurement properties in high-quality studies. The Haemophilia Well-Being Index and HAEMO-QoL-A performed best among the adult measures. None of the studies reported measurement error and responsiveness. Our findings suggest that there is no need for new disease-specific HRQOL questionnaires for haemophilia, but rather that additional research is necessary to document the measurement properties of the currently available questionnaires, specifically focusing on the structural validity, measurement error and responsiveness of these questionnaires. © 2017 John Wiley & Sons Ltd.

    Quality of life is often considered when deciding and evaluating the treatment strategy for patients diagnosed with anal fistula. The purpose of this study was to develop and psychometrically test the Quality of Life in Patients with Anal Fistula Questionnaire. This was an observational cross-sectional study for the development and validation of a psychometric tool. The study was conducted at a general hospital in the southeast of Spain. A convenience sample included 54 patients diagnosed with anal fistula. The reliability of the tool was assessed through its internal consistency (Cronbach α) and temporal stability (Spearman correlation coefficient (r) between test-retest). The content validity index of the items and the scale was calculated. Correlation analysis and an ordinal regression analysis between the developed tool and the Short Form 12 Health Survey examined its concurrent validity. Principal component analysis and known-group analysis using the Kruskal-Wallis test examined its construct validity. The reliability of the developed questionnaire was very high (α = 0.908; r = 0.861; p < 0.01). Its content validity was excellent (all-item content validity index = 0.79-1.00; scale validity index = 0.92). Evidence of its concurrent validity included strong correlation between the developed tool and Short Form 12 Health Survey (r = 0.734; p < 0.001), and participant scores on the developed tool explained ≈46.2% of the between-subject variation for the participant scores on Short Form 12 Health Survey (Nagelkerke R = 0.462). Confirming its construct validity, principal component analysis revealed that 2 factors explained 81.63% of the total variance found. Known-group analysis evidenced the ability of the questionnaire to detect expected differences in patients presenting with different symptomatology. The major limitations of this study were the use of a small sample of Spanish-speaking patients, not including patients in the initial development of the

    Actinic keratosis (AK) is a sun-induced skin lesion that may progress to invasive squamous cell carcinoma of the skin. Recently, the Actinic Keratosis Quality of Life questionnaire (AKQoL) was designed for patients with AK in Denmark as a specific quality of life instrument for AK patients. The objective of this study was to adapt the AKQoL for the German language region of Switzerland and to evaluate its psychometric properties (validity, reliability). Translation and cultural adaptation of the questionnaire were assessed by using the technique of cognitive interviewing. During the translation process, 34 patients with AK from the Department of Dermatology, University Hospital Zurich, were interviewed in 3 sessions of cognitive interviewing. The translated questionnaire was then distributed together with the Dermatology Life Quality Index (DLQI) to a second group of 113 patients for validation and reliability testing. Within this group, we measured the internal consistency by the Cronbach coefficient α and Spearman correlation coefficient between the AKQoL and the DLQI. The problems encountered during the translation process led to changes in 5 categories as described by Epstein: stylistic changes, change in breadth, change in actual meaning, change in frequency and time frame, change in intensity. We found a Cronbach α of 0.82, an acceptable internal consistency. The Spearman correlation coefficient between total scores of AKQoL and DLQI was 0.57. We culturally adapted and validated a Swiss (German) version of the AKQoL questionnaire applicable for the population of a university center in Switzerland to measure and monitor the quality of life in patients with AK. © 2018 S.

    Health-related quality of life (HRQOL), which is receiving increasing attention, is a multidimensional concept that encompasses different areas including the physiological, psychological, social, and spiritual aspects of life. The KIDSCREEN-52 questionnaire is designed to measure the HRQOL of 8-18-year-old children and adolescents. The aim of this study was to develop a Persian version of KIDSCREEN-52 and analyze the validity and reliability of the translated version. The KIDSCREEN-52 was translated into Persian in keeping with the international cross-cultural translation guidelines. A cross-sectional study was performed in the city of Tehran during 2012-2013. 328 students ranging in age from 8 to 18 years were enrolled in the study. The reliability for each dimension was estimated using Cronbach's alpha coefficient. To examine the validity of the questionnaire, a confirmatory factor analysis (CFA) was conducted. The Cronbach's alpha coefficient was higher than 0.7 in all ten dimensions except self-perception. Validity of this questionnaire was confirmed by CFA. (Relative chi square (χ (2)/df) = 1.73; root-mean-square error of approximation = 0.047; normed fit index = 0.93; Tucker-Lewis index = 0.97; comparative fit index = 0.97; and relative fit index = 0.92.) The Persian version of KIDSCREEN-52 is reliable and valid and can be used as a self-administered instrument for measuring HRQOL in children and adolescents in Iran.

    Treatments for autoimmune blistering disease carry significant risks of medical complications and can affect the patient's quality of life. Recently, the Treatment of Autoimmune Bullous Disease Quality of Life questionnaire was developed in Australia. The objective of this study was to evaluate the reliability and validity of the Chinese version of the Treatment of Autoimmune Bullous Disease Quality of Life questionnaire in Chinese patients with autoimmune blistering diseases. The Chinese version of the Treatment of Autoimmune Bullous Disease Quality of Life questionnaire was produced by forward-backward translation and cross-cultural adaptation of the original English version. Autoimmune blistering disease patients recruited in the study self-administered the Chinese Treatment of Autoimmune Bullous Disease Quality of Life questionnaire, the Dermatology Life Quality Index and the 36-item Short-Form Health Survey. Reliability of the Chinese Treatment of Autoimmune Bullous Disease Quality of Life was evaluated using internal consistency and test-retest (days 0 and 7) methods. Validity was analyzed by face, content, construct, convergent and discriminant validity measures. A total of 86 autoimmune blistering disease patients were recruited for the study. Cronbach's alpha coefficient was 0.883 and the intraclass correlation coefficient was 0.871. Face and content validities were satisfactory. Convergent validity testing revealed correlation coefficients of 0.664 for the Treatment of Autoimmune Bullous Disease Quality of Life and Dermatology Life Quality Index and -0.577 for the Treatment of Autoimmune Bullous Disease Quality of Life and 36-item Short-Form Health Survey. With respect to discriminant validity, no significant differences were observed in the Treatment of Autoimmune Bullous Disease Quality of Life scores of men and women (t = 0.251, P = 0.802), inpatients and outpatients (t = 0.447, P = 0.656), patients on steroids and steroid-sparing medications (t = 0

    Understanding how individuals value health states is central to patient-centered care and to health policy decision making. Generic preference-based measures of health may not effectively capture the impact of ocular diseases. Recently, 6 items from the National Eye Institute Visual Function Questionnaire-25 were used to develop the Visual Function Questionnaire-Utility Index health state classification, which defines visual function health states. To describe elicitation of preferences for health states generated from the Visual Function Questionnaire-Utility Index health state classification and development of an algorithm to estimate health preference scores for any health state. Nonintervention, cross-sectional study of the general community in 4 countries (Australia, Canada, United Kingdom, and United States). A total of 607 adult participants were recruited from local newspaper advertisements. In the United Kingdom, an existing database of participants from previous studies was used for recruitment. Eight of 15,625 possible health states from the Visual Function Questionnaire-Utility Index were valued using time trade-off technique. A θ severity score was calculated for Visual Function Questionnaire-Utility Index-defined health states using item response theory analysis. Regression models were then used to develop an algorithm to assign health state preference values for all potential health states defined by the Visual Function Questionnaire-Utility Index. Health state preference values for the 8 states ranged from a mean (SD) of 0.343 (0.395) to 0.956 (0.124). As expected, preference values declined with worsening visual function. Results indicate that the Visual Function Questionnaire-Utility Index describes states that participants view as spanning most of the continuum from full health to dead. Visual Function Questionnaire-Utility Index health state classification produces health preference scores that can be estimated in vision-related studies that

    To determine reproducibility and validity of an Argentine version of the Lupus Quality of Life questionnaire (LupusQoL) and to determine cut-off values in the questionnaire. One hundred and forty-seven systemic lupus erythematosus patients (American College of Rheumatology 1982/1997) were assessed from April 2014 to July 2014. Demographic and socioeconomic variables were collected, as well as SELENA/SLEDAI, Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index Score, comorbidities and treatment data. Patients completed LupusQoL-Argentine version and European Quality of Life Questionnaire (EuroQoL-5D). Internal consistency and reliability were examined. Convergent validity with EuroQoL-5D was assessed through analysis of latent classes, which established homogeneous categories from the responses of each domain of LupusQoL and for the total. Out of 147 patients, 93.2% were female, mean age 36.4 ± 11.1 years, mean disease duration 2.7 ± 9 years, mean SELENA/SLEDAI 2.7 ± 3 points. The cut-off point that defined good or bad quality of life was 0.739 for EuroQoL 5D and 63 for LupusQoL. Cut-off values for each LupusQoL domain were also defined, creating two classes in each of them. There was moderate to high concordance to classify quality of life (Kappa = 0.74, 95% confidence interval = 0.54, 0.95). The Argentine version of LupusQoL is a valid, reliable and reproducible instrument to assess quality of life. In this study, cut-off points that allow the classification of patients regarding whether they have good or bad quality of life are established for the first time. © The Author(s) 2016.

    Quality-of-life (QOL) evaluation is an increasingly important outcome measure in dermatology, with disease-specific QOL instruments being the most sensitive to changes in disease status. To develop a QOL instrument specific to autoimmune bullous disease (AIBD). A comprehensive item generation process was used to build a 45-item pilot Autoimmune Bullous Disease Quality of Life (ABQOL) questionnaire, distributed to 70 patients with AIBD. Experts in bullous disease refined the pilot ABQOL before factor analysis was performed to yield the final ABQOL questionnaire of 17 questions. We evaluated validity and reliability across a range of indices. Australian dermatology outpatient clinics and private dermatology practices. PATIENTS AND EXPOSURE: Patients with a histological diagnosis of AIBD. The development of an AIBD-specific QOL instrument. Face and content validity were established through the comprehensive patient interview process and expert review. In terms of convergent validity, the ABQOL was found to have a moderate correlation with scores on the Dermatology Life Quality Index (R = 0.63) and the General Health subscale of the 36-Item Short Form Health Survey (R = 0.69; P = .009) and low correlation with the Pemphigus Disease Area Index (R = 0.42) and Autoimmune Bullous Disease Skin Disorder Intensity Score (R = 0.48). In terms of discriminant validity, the ABQOL was found to be more sensitive than the Dermatology Life Quality Index (P = .02). The ABQOL was also found to be a reliable instrument evaluated by internal consistency (Cronbach α coefficient, 0.84) and test-retest reliability (mean percentage variation, 0.92). The ABQOL has been shown to be a valid and reliable instrument that may serve as an end point in clinical trials. Future work should include incorporating patient weighting on questions to further increase content validity and translation of the measure to other languages. anzctr.org.au Identifier: ACTRN12612000750886.

    In this paper, index for indoor air quality (also known as IAQI) and thermal comfort index (TCI) have been developed. The IAQI was actually modified from previous outdoor air quality index (AQI) designed by the United States Environmental Protection Agency (US EPA). In order to measure the index, a real-time monitoring system to monitor indoor air quality level was developed. The proposed system consists of three parts: sensor module cloud, base station and service-oriented client. The sensor module cloud (SMC) contains collections of sensor modules that measures the air quality data and transmit the captured data to base station through wireless. Each sensor modules includes an integrated sensor array that can measure indoor air parameters like Carbon Dioxide, Carbon Monoxide, Ozone, Nitrogen Dioxide, Oxygen, Volatile Organic Compound and Particulate Matter. Temperature and humidity were also being measured in order to determine comfort condition in indoor environment. The result from several experiments show that the system is able to measure the air quality presented in IAQI and TCI in many indoor environment settings like air-conditioner, chemical present and cigarette smoke that may impact the air quality. It also shows that the air quality are changing dramatically, thus real-time monitoring system is essential.

    The Consumer Quality Index Palliative Care (CQ-index PC) is a structured questionnaire for measuring the quality of palliative care from the perspective of care users. CQ-indices assess which care aspects need quality improvement by relating answers about actual care experiences to answers about the importance of certain aspects of care. To improve the chance that the new instrument has good content validity, a literature study and individual and group discussions were performed, and a steering committee was consulted to establish the instrument's face and content validity. The questionnaire was administered to patients with a life expectancy of 6 months or less and/or who were receiving palliative treatment. Descriptive analyses were carried out on the items about actual care experiences and the importance of care aspects, and on 'need for improvement' scores. 15 care organisations participated. 133 patients met the inclusion criteria (net response n=85). Patients considered the following aspects the most important: 'offering help in good time in acute situations', 'caregivers having the necessary expertise' and 'caregivers taking the patient seriously'. The three care aspects with the highest 'need for improvement' scores were: 'support when the patient feels depressed', 'support when the patient is anxious' and 'support when the patient has shortness of breath'. The CQ-index PC provides opportunities for care organisations to assess which care aspects have the highest priority for quality improvement within their organisation. Further research is needed to assess whether the instrument has enough discriminative power to assess differences between organisations.

    Objective This review is aimed at assessing the quality of questionnaires and their development process based on the theory of planned behavior (TPB) change model. Methods A systematic literature search for studies with the primary aim of TPB-based questionnaire development was conducted in relevant databases between 2002 and 2012 using selected search terms. Ten of 1,034 screened abstracts met the inclusion criteria and were assessed for methodological quality using two different appraisal tools: one for the overall methodological quality of each study and the other developed for the appraisal of the questionnaire content and development process. Both appraisal tools consisted of items regarding the likelihood of bias in each study and were eventually combined to give the overall quality score for each included study. Results 8 of the 10 included studies showed low risk of bias in the overall quality assessment of each study, while 9 of the studies were of high quality based on the quality appraisal of questionnaire content and development process. Conclusion Quality appraisal of the questionnaires in the 10 reviewed studies was successfully conducted, highlighting the top problem areas (including: sample size estimation; inclusion of direct and indirect measures; and inclusion of questions on demographics) in the development of TPB-based questionnaires and the need for researchers to provide a more detailed account of their development process.

    Indexing with computers is a far cry from indexing with the first indexing tool, the manual card sorter. With the aid of computer-aided lexicography, both indexing and indexing tools can provide standardization, consistency, and accuracy, resulting in greater quality control than ever before. A brief survey of computer activity in indexing is presented with detailed illustrations from NASA activity. Applications from techniques mentioned, such as Retrospective Indexing (RI), can be made to many indexing systems. In addition to improving the quality of indexing with computers, the improved efficiency with which certain tasks can be done is demonstrated.

    The purpose of this paper was to evaluate and compare the questionnaires regarding sleep quality among children aged up to 12 years old, used in the Portuguese language in Brazil. A search at the literature databases of Lilacs, Scielo and Pubmed was performed using keywords "sleep quality" and "children". Selected Articles were analysed for age of the studied population, the number of questions and the issues addressed thereby, who realized the application, the analysis of the results, and content. Out of 9377 titles, 11 studies were included, performing 7 different questionnaires: Questionnaire to measure quality of life among children with enlarged palatine and pharyngeal tonsils (translation of OSD-6) (1); Inventory of Sleep Habits for Preschool Children (2); the Questionnaire on Obstructive Sleep Apnoea-18 (OSA-18) (3), Sleep Questionnaire by Reimão and Lefévre - QRL (4); the Questionnaire on Sleep Behaviour Patterns (5) and the translation of the Sleep Disturbance Scale for Children (6); Brief Infant Sleep Questionnaire - BISQ (7) . Six of the questionnaires have covered the following issues: snoring and daytime sleepiness. A total of 7 protocols were found to be available in Brazil, the most commonly mentioned being OSA-18 and OSD-6. The use of protocols as a guided interview helps to define diagnosis and treatment among the paediatric population, but its large variability makes it difficult to compare a standardised monitoring process.

    The determinants of the health-related quality of life of women with polycystic ovary syndrome are not fully understood. The aim of this study was to develop a comprehensive instrument to assess the health-related quality of life of Iranian women with PCOS and to assess its psychometric properties. We used a mixed-method, sequential, exploratory design including both qualitative [in-depth interview to define the components of health-related quality of life questionnaire (PCOSQ)] and quantitative approaches (to assess the psychometric properties of PCOSQ). A preliminary questionnaire was developed including 147 items which emerged from the qualitative phase of the study. Considering the optimum cutoff points for content validity ratio (CVR), content validity index (CVI), and impact score, items of the preliminary questionnaire were reduced from 147 to 88 items. Finally, by excluding highly correlated items using the exploratory factor analysis, a 50-item questionnaire was obtained. The Kaiser criteria (eigenvalues >1) and Scree plot tests demonstrated that six factors were optimum with an estimated 47.3 % of variance. Assessment of the psychometric properties of the questionnaire demonstrated a mean CVI = 0.92, CVR = 0.91, Cronbach's alpha for whole questionnaire = 0.88 (0.61-0.88 for subscales), Spearman's correlation coefficients of test-retest = 0.75, and the intra-class correlation coefficient for the PCOS questionnaire subscales ranging from 0.57 to 0.88. Eventually the final questionnaire included 50 items in six domains, 'psychosocial and emotional,' 'fertility,' 'sexual function,' 'obesity and menstrual disorders,' 'hirsutism,' and 'coping' and rated on a 5-point Likert scale. The PCOSQ-50 is a valid and reliable instrument for the assessment of quality of life of women with PCOS, capable of assessing some obscure aspects overlooked by previous HRQL questionnaires.

    Retrospective design. To compare the responsiveness and test-retest reliability of the Functional Rating Index and the 18-item version of the Roland-Morris Disability Questionnaire in detecting change in disability in patients with work-related low back pain. Many low back pain-specific disability questionnaires are available, including the Functional Rating Index and the 18-item version of the Roland-Morris Disability Questionnaire. No previous study has compared the responsiveness and reliability of these questionnaires. Files of patients who had been treated for work-related low back pain at a physical therapy clinic were reviewed, and those containing initial and follow-up Functional Rating Index and 18-item Roland-Morris Disability Questionnaires were selected. The responsiveness of both questionnaires was compared using two different methods. First, using the assumption that patients receiving treatment improve over time, various responsiveness coefficients were calculated. Second, using change in work status as an external criterion to identify improved and nonimproved patients, Spearman's rho and receiver operating characteristic curves were calculated. Reliability was estimated from the subset of patients who reported no change in their condition over this period and expressed with the intraclass correlation coefficient and the minimal detectable change. One hundred and forty-three patient files were retrieved. The responsiveness coefficients for the Functional Rating Index were greater than for the 18-item Roland-Morris Disability Questionnaire. The intraclass correlation coefficient values for both questionnaires calculated from 96 patient files were similar, but the minimal detectable change for the Functional Rating Index was less than for the 18-item Roland-Morris Disability Questionnaire. The Functional Rating Index seems preferable to the 18-item Roland-Morris Disability Questionnaire for use in clinical trials and clinical practice.

    Persistent dizziness symptoms after cochlear implantation have an impact on quality of life. In this study, the effects of bilateral cochlear implants (CI) on quality of life as well as on subjective dizziness complaints are analyzed using questionnaires, some of which have never been applied before in these patient collectives. In this article, questionnaires for the assessment of dizziness symptoms and quality of life are introduced in order to realize quality assurance. A total of 32 patients with bilateral CI were questioned regarding dizziness symptoms and quality of life. The Nijmegen Cochlear Implant Questionnaire (NCIQ) was used. In the case of reported regular dizziness, the Vertigo Handicap Questionnaire (VHQ) and the Vertigo Symptom Scale (VSS) were also assessed. Persistent dizziness symptoms were shown in 8 of 32 patients. Quality of life was measured with the NCIQ and was improved significantly (p < 0.001) by 23.7% after the second CI. The dizziness symptoms changed slightly (VHQ -11.2%; VSS +16.4%) after the second implantation. The results show that the questionnaires are valid instruments for documenting quality of life and dizziness symptoms for quality assurance. These questionnaires may be applied as a complement or an alternative to device-based measurements of peripheral vestibular dysfunction.

    Obesity is associated to increased risk of metabolic comorbidity as well as increased mortality. Notably, obesity is also associated to the impairment of the psychological status and of quality of life. Only three questionnaires are available in the Italian language evaluating the health-related quality of life in subjects with obesity. The aim of the present study was to test the validity and reliability of the Italian version of the Laval Questionnaire. The original French version was translated into Italian and back-translated by a French native speaker. 273 subjects with obesity (Body Mass Index ≥ 30 kg/m 2 ) were enrolled; the Italian version of the Laval Questionnaire and the O.R.Well-97 questionnaire were administered in order to assess health- related quality of life. The Laval questionnaire consists of 44 items distributed in 6 domains (symptoms, activity/mobility, personal hygiene/clothing, emotions, social interaction, sexual life). Disability and overall psychopathology levels were assessed through the TSD-OC test (SIO test for obesity correlated disabilities) and the SCL-90 (Symptom Checklist-90) questionnaire, respectively. To verify the validity of the Italian version, the analysis of internal consistency, test-retest reliability, and construct validity were performed. The observed proportion of agreement concordance of results was 50.2% with Cohen's K = 0.336 (CI 95%: 0.267-0.404), indicating a fair agreement between the two tests. Test-retest correlation was statistically significant (ρ = 0.82; p < 0.01); validity (standardized Chronbach's alpha) was considered reliable (α > 0.70). The analysis of construct validity showed a statistically significant association in terms of both total score (ρ = -0.66) and scores at each single domain (p < 0.01). A high correlation (p < 0.01) was observed between Laval questionnaire total and single domain scores and other related measures (Body Mass Index, TSD-OC scores, SCL

    To develop and validate Health Related Quality of Life Questionnaire in Diabetic Foot Ulcer Patients (HRQLQDFU) for Indian scenario. This study was conducted in two phases. First phase was Development of HRQLQDFU which included literature search and expert interview. Second phase was validation of HRQLQDFL which included face validation, content validation and construct validation. Face validation was done by ten diabetic foot ulcer patients, ten practicing nurses and ten care givers. They were asked to read and respond to questionnaire and report any difficulty in understanding the questions. Further they were asked to add any item to the questionnaire which according to them has a significant effect on quality of life. Content validation was done by six subject experts who judged the content relevance of questionnaire with score ranging from zero to four; zero being least relevant and four being most relevant. Content validity index was calculated for each question. Questions having content validity index≥0.8 were selected for the study. Reliability was tested by calculating Cronbach's alpha. In the development phase a questionnaire containing 37 questions with six domains was developed. None of patient had difficulty in understanding questions. After content validation a new questionnaire containing 20 questions was developed. Cronbach's alpha was 0.86 which shows good reliability. The new health related quality of life questionnaire on diabetic foot ulcer patients for an Indian scenario is validated and can be a reliably measure for quality of life in diabetic foot ulcer patients.

    This study aims to describe the development, testing and optimization of a new standard instrument, the Consumer Quality Index (CQ-index) Long-term Care, for measuring client experiences with long-term care in the Netherlands. Three versions of the CQ-index questionnaires and protocols for study sampling and data collection were developed, designed for interviews with residents of nursing or residential care homes and postal surveys among representatives of psychogeriatric residents and homecare clients. From July to November 2006 a pilot study was conducted among 2,697 clients of 68 nursing or residential care homes, 2,164 representatives of clients in 57 psychogeriatric care institutions, and 1,462 clients of 19 homecare organizations. We performed psychometric analyses and descriptive analyses, and evaluated the pilot study. The pilot study showed the feasibility and usability of the instruments, supported the multidimensionality of the questionnaires and showed first findings on client experiences and possibilities for quality improvement. Nine scales applied to all care settings: shared decision making, attitude and courtesy, information, body care, competence and safety of care, activities, autonomy, mental well-being, and availability of personnel. The pilot resulted in three optimized questionnaires and recommendations for nationwide implementation. The CQ-index Long-term Care provides a good basis to investigate the quality of nursing homes, residential care homes and homecare from the clients' perspective. This standardized instrument enables a nationwide comparison of the quality of long-term care for the purpose of transparency and quality assurance.

    [Objective] Based on the water quality historical data from the Zhangze Reservoir from the last five years, the water quality was assessed by the integrated water quality identification index method and the Nemerow pollution index method. The results of different evaluation methods were analyzed and compared and the characteristics of each method were identified.[Methods] The suitability of the water quality assessment methods were compared and analyzed, based on these results.[Results] the water quality tended to decrease over time with 2016 being the year with the worst water quality. The sections with the worst water quality were the southern and northern sections.[Conclusion] The results produced by the traditional Nemerow index method fluctuated greatly in each section of water quality monitoring and therefore could not effectively reveal the trend of water quality at each section. The combination of qualitative and quantitative measures of the comprehensive pollution index identification method meant it could evaluate the degree of water pollution as well as determine that the river water was black and odorous. However, the evaluation results showed that the water pollution was relatively low.The results from the improved Nemerow index evaluation were better as the single indicators and evaluation results are in strong agreement; therefore the method is able to objectively reflect the water quality of each water quality monitoring section and is more suitable for the water quality evaluation of the reservoir.

    Clients' perspective on the quality of audiology care has not been investigated thoroughly. Research has focused primarily on satisfaction with, and limitations of hearing aids. We developed a Consumer Quality Index (CQI) questionnaire 'Audiology Care' to systematically assess client experiences with audiology care. The CQI Audiology Care was developed in three steps: (1) posing open-ended questions through e-mail (n = 14), (2) two small-scale surveys assessing psychometric properties of the questionnaire (n = 188) and importance of quality aspects (n = 118), and (3) a large-scale survey (n = 1793) assessing psychometric properties and discriminatory power of the questionnaire. People with complex hearing impairments and/or balance and communicative disorders who visited an audiology care centre during the past year. Important quality aspects were translated into seven reliable scales: accommodation and facilities, employees' conduct and expertise, arrangement of appointments, waiting times, client participation and effectiveness of treatment. Client experiences differed among the participating centres concerning accommodation and facilities, arrangement of appointments, waiting times and client participation. The CQI Audiology Care is a valid and reliable instrument to assess clients' experiences with audiology care. Future implementation will reveal whether results can be used to monitor and improve the quality of audiology care.

    2004-09-01

    A water quality index expressed as a single number is developed to describe overall water quality conditions using multiple water quality variables. The index consists of water quality variables: dissolved oxygen, specific conductivity, turbidity, total phosphorus, and fecal coliform. The objectives of this study were to describe the preexisting indices and to define a new water quality index that has advantages over these indices. The new index was applied to the Big Lost River Watershed in Idaho, and the results gave a quantitative picture for the water quality situation. If the new water quality index for the impaired water is less than a certain number, remediation-likely in the form of total maximum daily loads or changing the management practices-may be needed. The index can be used to assess water quality for general beneficial uses. Nevertheless, the index cannot be used in making regulatory decisions, indicate water quality for specific beneficial uses, or indicate contamination from trace metals, organic contaminants, and toxic substances.

    Development and validation of a questionnaire that measures patients' experiences of collaboration between general practitioners (GPs) and specialists. A questionnaire was developed using the method of the consumer quality index and validated in a cross-sectional study among a random sample of patients referred to medical specialists in the Netherlands. Validation included factor analysis, ascertain internal consistency, and the discriminative ability. The response rate was 65% (1404 patients). Exploratory factor analysis indicated that four domains could be distinguished (i.e. GP Approach; GP Referral; Specialist; Collaboration). Cronbach's alpha coefficients ranged from 0.51 to 0.93 indicating sufficient internal consistency to make comparison of groups of respondents possible. The Pearson correlation coefficients between the domains were <0.4, except between the domains GP Approach and GP Referral. All domains clearly produced discriminating scores for groups with different characteristics. The Consumer Quality Index (CQ-index) Continuum of Care can be a useful instrument to assess aspects of the collaboration between GPs and specialists from patients' perspective. It can be used to give feedback to both medical professionals and policy makers. Such feedback creates an opportunity for implementing specific improvements and evaluating quality improvement projects. 2009 Elsevier Ireland Ltd.

    The ever increasing level of air pollution in most areas of the world has led to development of a variety of air quality indices for estimation of health effects of air pollution, though the indices have their own limitations such as high levels of subjectivity. Present study, therefore, aimed at developing a novel, fuzzy-based air quality index (FAQI ) to handle such limitations. The index developed by present study is based on fuzzy logic that is considered as one of the most common computational methods of artificial intelligence. In addition to criteria air pollutants (i.e. CO, SO 2, PM 10, O 3, NO 2), benzene, toluene, ethylbenzene, xylene, and 1,3-butadiene were also taken into account in the index proposed, because of their considerable health effects. Different weighting factors were then assigned to each pollutant according to its priority. Trapezoidal membership functions were employed for classifications and the final index consisted of 72 inference rules. To assess the performance of the index, a case study was carried out employing air quality data at five different sampling stations in Tehran, Iran, from January 2008 to December 2009, results of which were then compared to the results obtained from USEPA air quality index (AQI). According to the results from present study, fuzzy-based air quality index is a comprehensive tool for classification of air quality and tends to produce accurate results. Therefore, it can be considered useful, reliable, and suitable for consideration by local authorities in air quality assessment and management schemes. Fuzzy-based air quality index (FAQI).

    Introduction The purpose of this paper was to evaluate and compare the questionnaires regarding sleep quality among children aged up to 12 years old, used in the Portuguese language in Brazil. Material and methods A search at the literature databases of Lilacs, Scielo and Pubmed was performed using keywords “sleep quality” and “children”. Selected Articles were analysed for age of the studied population, the number of questions and the issues addressed thereby, who realized the application, the analysis of the results, and content. Results Out of 9377 titles, 11 studies were included, performing 7 different questionnaires: Questionnaire to measure quality of life among children with enlarged palatine and pharyngeal tonsils (translation of OSD-6) (1); Inventory of Sleep Habits for Preschool Children (2); the Questionnaire on Obstructive Sleep Apnoea-18 (OSA-18) (3), Sleep Questionnaire by Reimão and Lefévre - QRL (4); the Questionnaire on Sleep Behaviour Patterns (5) and the translation of the Sleep Disturbance Scale for Children (6); Brief Infant Sleep Questionnaire - BISQ (7) . Six of the questionnaires have covered the following issues: snoring and daytime sleepiness. Conclusions A total of 7 protocols were found to be available in Brazil, the most commonly mentioned being OSA-18 and OSD-6. The use of protocols as a guided interview helps to define diagnosis and treatment among the paediatric population, but its large variability makes it difficult to compare a standardised monitoring process.

    Assessing patient satisfaction could be particularly useful in Day Surgery Units, as it helps maintaining and increasing medical care demand. Moreover, it provides feedback that turns out useful for improving quality in departments, and for assessing competence and skill of the whole staff. Background and aim - The purpose of this study was to evaluate the quality perceived in a day surgery unit through a questionnaire, covering the 10 main aspects of the care pathway. The results of a questionnaire filled by patients undergoing Day Surgery between January 2007 and December 2012 were retrospectively reviewed. Patients undergoing surgery between 2007 and 2009 filled up the questionnaire at the time of the discharge, whereas those operated on between 2009 and 2012 filled up the same questionnaire 30 days after discharge. The results were good in terms of number of returned questionnaires, underlining its comprehensibility and suitability to be filled out. The questionnaires' scores were good in both groups, although quality perceived by the group that completed it in 30 days after surgery were lightly better than the other group's. The advantages of the questionnaire consisted of an overall improvement of the quality of care, whereas limitations consisted of the difficulty in setting up the questionnaire accurately, interpreting patients' answers correctly, and dispensing the questionnaire in a timely fashion, in order to evaluate the quality perceived by the patients without any bias related to delay, pain and anxiety.

    The importance of quality of life (QOL) as an endpoint and the use of validated QOL questionnaires have increased over time. To evaluate health-related quality of life (HR-QOL) measurement instruments used in patients in otorhinolaryngology (ORL). We aimed to establish the use of QOL questionnaires in ORL over a period of time, establish the use of QOL questionnaires within different domains and determine the use of validated QOL questionnaires. We performed a comprehensive search in PubMed up to 1 January 2014. Articles were included that measured HR-QOL questionnaires in clinical practice in children, adolescents or adults in 42 journals of ORL. Multiple unique QOL questionnaires, organised according to domain, time and survey of validation, were extracted from reported articles. Of 2442 articles, we utilised 1196 publications with a total of 2103 QOL questionnaires regarding ORL. We evaluated a variety of 363 unique QOL questionnaires in which 60% (n = 220) QOL questionnaires had been validated. We found a continuing increase in the amount of articles which used QOL questionnaires since the beginning of the 20th century, while the percentage of validated QOL questionnaires remained the same (76%). Most QOL questionnaires were used in the domains oncology (35%), otology (21%) and rhinology (20%). The domain otology had the largest amount of unique QOL questionnaires (n = 122). We identified and evaluated all unique HR-QOL questionnaires utilised in patients in ORL. Recently, the use of validated and non-validated HR-QOL questionnaires has increased within all domains of ORL. The assessment of QOL has become an important outcome measure in clinical practice, in medical research and for healthcare organisations. © 2015 John Wiley & Sons Ltd.

    The McGill Quality of Life Questionnaire has been widely used with people with life-threatening illnesses without modification since its publication in 1996. With use, areas for improvement have emerged; therefore, various minor modifications were tested over time. To revise the McGill Quality of Life Questionnaire (McGill Quality of Life Questionnaire-Revised) while maintaining or improving its psychometric properties and length, keeping it as close as possible to the McGill Quality of Life Questionnaire to enable reasonable comparison with existing McGill Quality of Life Questionnaire literature. Data sets from eight studies were used (four studies originally used to develop the McGill Quality of Life Questionnaire, two to develop new McGill Quality of Life Questionnaire versions, and two with unrelated purposes). The McGill Quality of Life Questionnaire-Revised was developed using analyses of measurement invariance, confirmatory factor analysis, and calculation of correlations with the McGill Quality of Life Questionnaire's global quality of life item. Data were from 1702 people with life-threatening illnesses recruited from acute and palliative care units, palliative home care services, and oncology and HIV/AIDS outpatient clinics. The McGill Quality of Life Questionnaire-Revised consists of 14 items (plus the global quality of life item). A new Physical subscale was created combining physical symptoms and physical well-being and a new item on physical functioning. The Existential subscale was reduced to four items. The revised Support subscale, renamed Social, focuses more on relationships. The Psychological subscale remains unchanged. Confirmatory factor analysis results provide support for the measurement structure of the McGill Quality of Life Questionnaire-Revised. The overall scale has good internal consistency reliability ( α = 0.94). The McGill Quality of Life Questionnaire-Revised improves on and can replace the McGill Quality of Life

    Patients with Addison's disease reproducibly self-report impairment in specific dimensions of general well-being questionnaires, suggesting particular deficiencies in health-related quality-of-life (HRQoL). We sought to develop an Addison's disease-specific questionnaire (AddiQoL) that could better quantify altered well-being and treatment effects. Design, Setting, Patients, Intervention, and Outcomes: We reviewed the literature to identify HRQoL issues in Addison's disease and interviewed patients and their partners in-depth to explore various symptom domains. A list of items was generated, and nine expert clinicians and five expert patients assessed the list for impact and clarity. A preliminary questionnaire was presented to 100 Addison's outpatients; the number of items was reduced after analysis of the distribution of the responses. The final questionnaire responses were assessed by Cronbach's alpha and Rasch analysis. Published studies of HRQoL in Addison's disease indicated reduced vitality and general health perception and limitations in physical and emotional functioning. In-depth interviews of 14 patients and seven partners emphasized the impact of the disease on the emotional domain. Seventy HRQoL items were generated; after the expert consultation process and pretesting in 100 patients, the number of items was reduced to 36. Eighty-six patients completed the final questionnaire; the responses showed high internal consistency with Cronbach's alpha 0.95 and Person Separation Index 0.94 (Rasch analysis). We envisage AddiQoL having utility in trials of hormone replacement and management of patients with Addison's disease, analogous to similar questionnaires in GH deficiency (AGHDA) and acromegaly (AcroQoL).

    Assessing quality of care from the patient's perspective is considered to be highly relevant. As a standardized instrument in dermatology was lacking, we developed a patient experience questionnaire regarding chronic skin disease care: the Consumer Quality Index Chronic Skin Disease (CQI-CSD). (i) To evaluate the dimensional structure of the CQI-CSD, (ii) to assess its ability to distinguish between hospitals according to patients' experiences with quality of care, (iii) to explore patients' experiences with dermatological care and priorities for quality improvement according to the patients, and (iv) to optimize the questionnaire based on psychometric results and stakeholders' input. In a cross-sectional study 5647 adult patients who received dermatological care in the past 12 months in 20 hospitals were randomly selected and invited to fill out the questionnaire. Overall 1160 of 3989 eligible respondents (29% response rate, 30-87 per hospital) were included for analysis. The CQI-CSD comprised seven scales with high internal consistency (Cronbach's α = 0·74-0·92). The instrument's discriminative power was limited. Patients were positive about the care provided by nurses and doctors, but the provision of information by healthcare providers, accessibility of care and patient involvement could be improved. We optimized the CQI-CSD, resulting in a revised questionnaire containing 65 items. In conclusion, the CQI-CSD is a useful instrument to measure patient experiences with dermatological care. © 2015 British Association of Dermatologists.

    Introduction Assessing service quality is one of the basic requirements to develop the medical tourism industry. There is no valid and reliable tool to measure service quality of medical tourism. This study aimed to determine the reliability and validity of a Persian version of medical tourism service quality questionnaire for Iranian hospitals. Methods To validate the medical tourism service quality questionnaire (MTSQQ), a cross-sectional study was conducted on 250 Iraqi patients referred to hospitals in Ahvaz (Iran) from 2015. To design a questionnaire and determine its content validity, the Delphi Technique (3 rounds) with the participation of 20 medical tourism experts was used. Construct validity of the questionnaire was assessed through exploratory and confirmatory factor analysis. Reliability was assessed using Cronbach’s alpha coefficient. Data were analyzed by Excel 2007, SPSS version18, and Lisrel l8.0 software. Results The content validity of the questionnaire with CVI=0.775 was confirmed. According to exploratory factor analysis, the MTSQQ included 31 items and 8 dimensions (tangibility, reliability, responsiveness, assurance, empathy, exchange and travel facilities, technical and infrastructure facilities and safety and security). Construct validity of the questionnaire was confirmed, based on the goodness of fit quantities of model (RMSEA=0.032, CFI= 0.98, GFI=0.88). Cronbach’s alpha coefficient was 0.837 and 0.919 for expectation and perception questionnaire. Conclusion The results of the study showed that the medical tourism SERVQUAL questionnaire with 31 items and 8 dimensions was a valid and reliable tool to measure service quality of medical tourism in Iranian hospitals.

    Aim To assess the relationship between sleep quality and demographic variables, morning-evening type, and burnout in nurses who work shifts. Methods We carried out a cross-sectional self-administered study with forced choice and open-ended structured questionnaires – Pittsburg Sleep Quality Index, Morningness-eveningness Questionnaire, and Maslach Burnout Inventory. The study was carried out at Gazi University Medicine Faculty Hospital of Ankara on 524 invited nurses from July to September 2008, with a response rate of 89.94% (n = 483). Descriptive and inferential statistics were applied to determine the risk factors of poor sleep quality. Results Most socio-demographic variables did not affect sleep quality. Participants with poor sleep quality had quite high burnout levels. Most nurses who belonged to a type that is neither morning nor evening had poor sleep quality. Nurses who experienced an incident worsening their sleep patterns (P < 0.001) and needlestick or sharp object injuries (P = 0.010) in the last month had poor sleep quality. The subjective sleep quality and sleep latency points of evening types within created models for the effect of burnout dimensions were high. Conclusions Nurses working consistently either in the morning or at night had better sleep quality than those working rotating shifts. Further studies are still needed to develop interventions that improve sleep quality and decrease burnout in nurses working shifts. PMID:21853548

    Melasma, which is fairly common in Indians, causes significant emotional and psychological impact. A Hindi instrument would be useful to assess the impact of melasma on the quality of life in Indian patients. To create a semantic equivalent of the original MELASQOL questionnaire in Hindi and validate it. A Hindi adaptation of the original MELASQOL (Hi-MELASQOL) was prepared using previously established guidelines. After pre-testing, the Hi-MELASQOL questionnaire was administered to 100 women with melasma visiting the out-patient registration counter of Safdarjung Hospital, Delhi. These women were also administered a Hindi equivalent of the Health Related Quality of Life (HRQOL) questionnaire. Melasma area severity index (MASI) of all the participants was calculated. The mean MASI score was 20.0 ± 7.5 and Hi-MELASQOL score was 37.19 ± 18.15; both were highly, positively and significantly correlated. Reliability analysis showed satisfactory results. Physical health, emotional well-being and social life were the most adversely affected life domains. It was a single-center study and the number of patients studied could have been larger. Hi-MELASQOL is a reliable and validated tool to measure the quality of life in Indians with melasma.

    We investigate the effects of a massage therapy program (MTP) in cortisol concentration (CC), intensity of pain, quality of life and perceived stress index of fibromyalgia patients. Volunteers (n = 24, aged 26-55 years) were treated with MT, twice a week for three months. They answered the Fibromyalgia Impact Questionnaire (FIQ), Perceived Stress Questionnaire (PSQ) and McGill Pain Questionnaire (MPQ-Br), and collected saliva to evaluate CC before and after the end of each month. The MT had improvement in quality of life, according to the FIQ results, and promoted reduction in PSQ values after the second (PSQ2-0.62 ± 0.04vsPSQ0-0.71 ± 0.04) and third month (PSQ3-0.64 ± 0.04vsPSQ0-0.71 ± 0.04). The MTP also promoted reduction in pain after the third month (MQP-Br1-44.50 ± 2.15vsMQP-Br4-35.38 ± 3.71). Despite PSQ reduction, the CC were not affected by the program. This pilot suggests that this treatment improved quality of life, reduced perceived stress index and pain in these volunteers. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The autoimmune bullous diseases quality of life (ABQOL) questionnaire was recently developed by an Australian group and has been validated in Australian and North American patient cohorts. It is a 17-item, multidimensional, self-administered English questionnaire. The study aimed to validate the Chinese version of the ABQOL questionnaire and evaluate the reliability in Chinese patients. The Chinese version of the ABQOL questionnaire was produced by forward-backward translation and cross-cultural adaptation of the original English version. The ABQOL questionnaire was then distributed to a total of 101 patients with autoimmune bullous diseases (AIBDs) together with the Dermatology Life Quality Index (DLQI) and the 36-item Short Form Health Survey (SF-36). Validity was analyzed across a range of indices and reliability was assessed using internal consistency and test-retest methods. The Chinese version of the ABQOL questionnaire has a high internal consistency (Cronbach's alpha coefficient, 0.88) and test-retest reliability (the intraclass correlation coefficient, 0.87). Face and content validity were satisfactory. Convergent validity testing showed that the correlation coefficients for the ABQOL and DLQI was 0.77 and for the ABQOL and SF-36 was -0.62. In terms of discriminant validity, there was no significant difference between the proportions of insensitive items in ABQOL and DLQI (p = 0.236). There was no significant difference between the proportions of insensitive items in ABQOL and SF-36 (p = 0.823). The Chinese version of the ABQOL questionnaire has adequate validity and reliability. It may constitute a useful instrument to measure disease burden in Chinese patients with AIBDs.

    It is believed that vitiligo has an impact on the overall patient quality of life (QoL). To estimate QoL in a fairly large sample of Italian vitiligo patients by using the Dermatology Life Quality Index (DLQI) questionnaire. One hundred and sixty-one vitiligo patients referred to 9 dermatological centers were offered to participate by filling in the Italian version of the DLQI questionnaire. The mean total DLQI score was 4.3 (SD ±4.9; range: 0-22). In multivariate analysis, DLQI >5 was associated with female gender, stability of the disease over time and involvement of the face at disease onset. The impairment of QoL is overall limited in Italian vitiligo patients, especially if it is compared with results from other available studies. This could be due to cultural and ethnic characteristics of the sample.

    The aim of this study was to analyze the impact of patient age and education level on the comprehension of the Turkish version of Index of Erectile Function (IIEF), and to determine the patient characteristics that make this questionnaire less reliable. In this study, 238 male patients presenting to our clinic were enrolled. The patients were asked to complete the Turkish version of the IIEF questionnaire upon arrival by themselves and then once again during their second visit with the assistance of a physician. 'Accurate' comprehension of the IIEF was considered to be the consistency between the 'self-administered' and 'physician-assisted' IIEF scores. The impact of patient age and education level on the 'accurate' comprehension of the IIEF was analyzed. There was a significant difference between the 'self-administered' and 'physician-assisted' IIEF scores in patients ≥ 60 years of age (P=0.045) and primary school graduates (P=0.015). Age ≥ 60 years and being primary school graduate are factors lowering the comprehension of the Turkish version of the IIEF by the patients. Older patients and patients with lower education could benefit from the assistance of a physician while completing this questionnaire.

    Surgical treatment of anorectal malformations (ARMs) and Hirschsprung's disease (HD) leads to alterations in bowel habits and fecal incontinence, with consequent quality of life impairment. The objectives were to create and validate a Questionnaire for the Fecal Incontinence Index (FII) based on the Holschneider score, as well as a Questionnaire for the Assessment of Quality of Life Related to Fecal Incontinence in Children and Adolescents (QQVCFCA), based on the Fecal Incontinence Quality of Life. The questionnaires were applied to 71 children submitted to surgical procedure, in two stages. Validity was tested by comparing the QQVCFCA and a generic quality of life questionnaire (SF-36), and between QQVCFCA and the FII. A group of 59 normal children was used as control. At two stages, 45.0% (32/71) and 42.8% (21/49) of the patients had fecal incontinence. It was observed that the QQVCFCA showed a significant correlation with the SF-36 and FII (Pearson's correlation 0.57), showing that the quality of life is directly proportional to improvement in fecal incontinence. Quality of life in patients with fecal incontinence is still globally impaired, when compared with control subjects (p<0.05, Student's t test). There were also significant differences between the results of children with ARMs and children with HD. QQVCFCA and FII are useful tools to assess the quality of life and fecal incontinence in these groups of children. Children with ARMs submitted to surgical procedure and HD have similar quality of life impairment. Copyright © 2015 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda.

    The Leicester Cough Questionnaire (LCQ) is one of the few specific quality-of-life questionnaires (QOLQ) dedicated to measuring the impact of chronic cough on patients' health/condition. The aim of the study was to validate the Polish version of the LCQ. The LCQ was translated forward and backward. The Polish version of the LCQ was tested on 35 patients suffering from chronic cough (23 women, median age 60 years, nonor ex-smokers, median cough duration of 23 weeks). Its validity was tested by comparison to a visual analogue scale (VAS) of cough intensity and other health questionnaires (hospital anxiety and depression scale - HADS, Euro-Quality of Life Questionnaire - EQ5D, St. George's Respiratory Questionnaire - SGRQ). The internal reliability of the Polish version of the LCQ was determined using the Cronbach alpha coefficient and its repeatability by the intraclass consistency coefficient. The translation of the LCQ into Polish was accepted by the author of the original LCQ. The Cronbach's alpha coefficient for total LCQ was 0.89, and reached 0.82, 0.86 and 0.78 for the physical, psychological and social domain, respectively. There were significant negative correlations between cough severity measured by VAS, the results of the EQ5D and SGRQ and the Polish version of the LCQ. The intraclass correlation coefficient of the test-retest reliability was significant (0.99). The Polish version of the LCQ has been validated and is a reliable tool to measure the impact of chronic cough on quality of life of patients with chronic cough.

    General questionnaires are often used to assess quality of life in patients with spine metastases, although a disease-specific survey did not exist until recently. The Spine Oncology Study Group has developed an outcomes questionnaire (SOSG-OQ) to measure quality of life in these patients. However, a scoring system was not developed, and the questionnaire was not validated in a group of patients, nor was it compared with other general quality of life questionnaires such as the EuroQol 5 Dimensions (EQ-5D) questionnaire. Our primary null hypothesis is that there is no association between the SOSG-OQ and EQ-5D. Our secondary null hypothesis is that there is no difference in coverage and internal consistency between the SOSG-OQ and EQ-5D. We also assess coverage, consistency, and validity of the domains within the SOSG-OQ. A survey study from a tertiary care spine referral center was used for this study. The patient sample consisted of 82 patients with spine metastases, myeloma, or lymphoma. The SOSG-OQ (27 questions, 6 domains) score ranges from 0 to 80, with a higher score indicating worse quality of life. The EQ-5D (5 questions, 5 domains) index score ranges from 0 to 1, with a higher score indicating better quality of life. The association between the SOSG-OQ and EQ-5D index score was assessed using the Spearman rank correlation. Instrument coverage and precision were assessed by determining item completion rate, median score with range, and floor and ceiling effect. Internal consistency was assessed using Cronbach alpha. Multitrait analysis and exploratory factor analysis were used to analyze properties of the individual domains in the SOSG-OQ. The Spearman rank correlation between the SOSG-OQ and EQ-5D questionnaire was high (r=-0.83, p<.001). Internal consistency of the SOSG-OQ (0.92, 95% CI: 0.89-0.94) was higher as compared to the internal consistency of the EQ-5D (0.73, 95% CI: 0.63-0.84; p<.001). The SOSG-OQ score had no floor or ceiling effect indicating

    Background This study explored the psychometric properties (internal consistency, construct validity, discriminative ability) of the Juniper Mini Asthma Quality of Life Questionnaire (Mini AQLQ-J) and the Sydney Asthma Quality of Life Questionnaire (AQLQ-S). Methods One hundred fourty-six adults (18–45 years) with asthma requiring regular inhaled corticosteroids were recruited to a trial of written emotional disclosure. Correlational analyses were performed to understand the relationship of the two measures with each other, with symptoms, lung function, asthma control, asthma bother and generic quality of life. Median quality of life scores were compared according to gender, health care usage and levels of asthma severity. Results AQLQ-J and AQLQ-S total scores correlated strongly with each other (rho = −0.80) and moderately with the EuroQol Current Health Status Scale (AQLQ-J: rho = 0.35; AQLQ-S: rho = −0.40). Domain score correlations between AQLQ-J and AQLQ-S were mostly moderate (0.50 < rho < 0.80). Both QoL measures were significantly correlated with symptom score. Correlations with the symptom score asthma module (AQLQ-J: rho = −0.69; AQLQ-S: rho = 0.50) were stronger compared with the total symptom score and the symptom score rhinitis module (AQLQ-J: rho = −0.41; AQLQ-S: rho =0.31). Neither QoL measure was significantly correlated with FEV1, % predicted at the total or the domain level. Total scores of both measures were significantly correlated with subjective asthma control (AQLQ-J: rho = 0.68; AQLQ-S: rho = −0.61) and asthma bother (AQLQ-J: rho = −0.73; AQLQ-M: rho = 0.73). Total AQLQ-J score and total AQLQ-S score were significantly associated with perceived asthma severity (AQLQ-J: p=0.004, AQLQ-S: p=0.002) and having visited a GP in the past four months (AQLQ-J: p=0.003, AQLQ-S: p=0.002).

    Patients' experiences are an indicator of health-care performance in the accident and emergency department (A&E). The Consumer Quality Index for the Accident and Emergency department (CQI A&E), a questionnaire to assess the quality of care as experienced by patients, was investigated. The internal consistency, construct validity and discriminative capacity of the questionnaire were examined. In the Netherlands, twenty-one A&Es participated in a cross-sectional survey, covering 4883 patients. The questionnaire consisted of 78 questions. Principal components analysis determined underlying domains. Internal consistency was determined by Cronbach's alpha coefficients, construct validity by Pearson's correlation coefficients and the discriminative capacity by intraclass correlation coefficients and reliability of A&E-level mean scores (G-coefficient). Seven quality domains emerged from the principal components analysis: information before treatment, timeliness, attitude of health-care professionals, professionalism of received care, information during treatment, environment and facilities, and discharge management. Domains were internally consistent (range: 0.67-0.84). Five domains and the 'global quality rating' had the capacity to discriminate among A&Es (significant intraclass correlation coefficient). Four domains and the 'global quality rating' were close to or above the threshold for reliably demonstrating differences among A&Es. The patients' experiences score on the domain timeliness showed the largest range between the worst- and best-performing A&E. The CQI A&E is a validated survey to measure health-care performance in the A&E from patients' perspective. Five domains regarding quality of care aspects and the 'global quality rating' had the capacity to discriminate among A&Es. © 2013 John Wiley & Sons Ltd.

  5. Utility of brief questionnaires of health-related quality of life (Airways Questionnaire 20 and Clinical COPD Questionnaire) to predict exacerbations in patients with asthma and COPD

    Background There is some evidence that quality of life measured by long disease-specific questionnaires may predict exacerbations in asthma and COPD, however brief quality of life tools, such as the Airways Questionnaire 20 (AQ20) or the Clinical COPD Questionnaire (CCQ), have not yet been evaluated as predictors of hospital exacerbations. Objectives To determine the ability of brief specific health-related quality of life (HRQoL) questionnaires (AQ20 and CCQ) to predict emergency department visits (ED) and hospitalizations in patients with asthma and COPD, and to compare them to longer disease-specific questionnaires, such as the St George´s Respiratory Questionnaire (SGRQ), the Chronic Respiratory Disease Questionnaire (CRQ) and the Asthma Quality of Life Questionnaire (AQLQ). Methods We conducted a two-year prospective cohort study of 208 adult patients (108 asthma, 100 COPD). Baseline sociodemographic, clinical, functional and psychological variables were assessed. All patients completed the AQ20 and the SGRQ. COPD patients also completed the CCQ and the CRQ, while asthmatic patients completed the AQLQ. We registered all exacerbations that required ED or hospitalizations in the follow-up period. Differences between groups (zero ED visits or hospitalizations versus ≥ 1 ED visits or hospitalizations) were tested with Pearson´s X2 or Fisher´s exact test for categorical variables, ANOVA for normally distributed continuous variables, and Mann–Whitney U test for non-normally distributed variables. Logistic regression analyses were performed to estimate the predictive ability of each HRQoL questionnaire. Results In the first year of follow-up, the AQ20 scores predicted both ED visits (OR: 1.19; p = .004; AUC 0.723) and hospitalizations (OR: 1.21; p = .04; AUC 0.759) for asthma patients, and the CCQ emerged as independent predictor of ED visits in COPD patients (OR: 1.06; p = .036; AUC 0.651), after adjusting for sociodemographic, clinical, and

    Parks are important resources for physical activity (PA), yet few studies have examined how perceptions of park characteristics relate to PA and health. This study investigated associations between perceptions of neighborhood park quality and overall moderate-to-vigorous PA (MVPA), park-based PA, and body mass index (BMI). Data were collected via questionnaire from 893 households in Kansas City, Missouri. The newly developed neighborhood park quality scale demonstrated good test-retest and internal reliability. Residents' perceptions of neighborhood park quality were related to PA and health outcomes. Perceiving parks as a benefit was positively related to overall MVPA and park-based PA and negatively related to BMI. Perceptions of well-used parks were positively related to BMI, while perceived cleanliness was negatively related to park-based PA. Better measuring and understanding how perceptions of local parks are associated with PA and health can improve appreciation of how parks facilitate active living.

    Purpose To validate the Quality of Erection Questionnaire (QEQ) considering Brazilian social-cultural aspects. Materials and Methods To determine equivalence between the Portuguese and the English QEQ versions, the Portuguese version was back-translated by two professors who are native English speakers. After language equivalence had been determined, urologists considered the QEQ Portuguese version suitable. Men with self-reported erectile dysfunction (ED) and infertile men who had a stable sexual relationship for at least 6 months were invited to answer the QEQ, the International Index of Erectile Function (IIEF) and the RAND 36-Item Health Survey (RAND-36). The questionnaires were presented together and answered without help in a private room. Internal consistency (Cronbach’s α), test-retest reliability (Spearman), convergent validity (Spearman correlation) coefficients and known-groups validity (the ability of the QEQ Portuguese version to differentiate erectile dysfunction severity groups) were assessed. Results We recruited 197 men (167 ED patients and 30 non-ED patients), mean age of 53.3 and median of 55.5 years (23-82 years). The Portuguese version of the QEQ had high internal consistency (Cronbach α=0.93), high stability between test and retest (ICC 0.83, with IC 95%: 0.76-0.88, p<0.001) and Spearman correlation coefficient r=0.82 (p<0.001), which demonstrated the high correlation between the QEQ and IIEF results. The correlations between the QEQ and RAND-36 were significantly low in ED (r=0.20, p=0.01) and non-ED patients (r=0.37, p=0.04). Conclusion The QEQ Portuguese version presented good psychometric properties and high convergent validity in relation to IIEF. The low correlations between the QEQ and the RAND-36, as well as between the IIEF and the RAND-36 indicated IIEF and QEQ specificity, which may have resulted from the patients’ psychological adaptations that minimized the impact of ED on Quality of Life (QoL) and reestablished the well

    This study reports the psychometric validation of a new HIV/AIDS-specific health-related quality of life (HRQL) questionnaire, the Patient Reported Outcomes Quality of Life-HIV. The instrument was developed simultaneously across Europe, North and South America, Africa, Asia, and Australia to assess multidimensional quality of life impairments in the era of highly active antiretroviral therapy. A cross-sectional study was performed in 8 countries. The pilot 70-item questionnaire was co-administered with the HIV symptoms index, the EQ-5D and Medical Outcomes Study-HIV questionnaires. Demographic and biomedical data were collected. After item analysis and reduction, convergent discriminant concurrent validity and known-group validity were examined. Internal consistency and reliability scores were assessed using Cronbach alpha and intraclass correlation. The final sample of 791 patients was composed of 64% males (median age: 41 years, HIV diagnosis = 5 years), 13.8% were treatment naive. Item reduction yielded a 43-item form surveying 8 dimensions and 1 global health item that showed good convergent and discriminant validity and reliability (98% scaling success; Cronbach alphas 0.77-0.89). Correlations with EQ-5D and Medical Outcomes Study-HIV complied with concurrent validity expectations; likewise, correlations against the number of self-reported symptoms and depression showed good support for criterion validity. A test-retest study on French patients (n = 34) showed temporal stability (intraclass correlation coefficient = 0.86). Significant and meaningful differences of HRQL scores between countries were found. The Patient Reported Outcomes Quality of Life-HIV questionnaire is a valid and reliable instrument for assessing HRQL specific to HIV disease in different cultures and healthcare systems.

    Objectives It is not known which of the many asthma-specific quality of life (QoL) questionnaires best capture the lived experience of people with asthma. The objective of this study was to explore patients' views of three commonly used asthma-specific QoL questionnaires. Design Qualitative study using semistructured interviews. Setting Primary and secondary care in Brighton and Hove, UK. Participants 30 adult people with a physician-diagnosis of asthma who were asked to complete the Juniper Asthma Quality of Life Questionnaire (AQLQ-J), the Sydney Asthma Quality of Life Questionnaire (AQLQ-S) and the Living with Asthma Questionnaire (LWAQ) to elicit their views on the content validity of these. Results Thematic content analysis revealed a lack of congruence between the concerns of people with asthma and the questionnaire content in terms of missing (eg, allergies) and irrelevant (eg, smoky restaurants) content. The AQLQ-J was perceived as a ‘narrow’, ‘medical’ questionnaire focused on symptoms, the environment and functional ability. In contrast, the LWAQ and the AQLQ-S were perceived to be ‘non-medical’. The LWAQ was described as a ‘test’ and as a wide-ranging, embracing and holistic questionnaire. Its strong emotional focus was irritating to some. The AQLQ-S was described as a simple, quick and easy questionnaire, although there was a perception that it was lacking in depth. Conclusions Patient interviews highlighted strengths and shortcomings in the content validity of these three asthma-specific questionnaires. For patients, the AQLQ-S content seemed to be the most pertinent in its adequacy of coverage of medical, social and emotional aspects of health-related QoL in asthma. PMID:28007706

    Poor sleep quality contributes to the inferior quality of life of patients with Parkinson's disease (PD) despite appropriate treatment of motor symptoms. The literature about the impact of sleep quality on quality of life of patients with PD is as yet sparse. One hundred patients of PD diagnosed as per UK Brain Bank criteria were assessed for severity and stage of PD using UPDRS and modified Hoehn &Yahr scales. The quality of sleep was assessed by Pittsburgh Sleep Quality Index and excessive daytime somnolence (EDS) was evaluated using Epworth Sleepiness Scale. Parkinson's Disease Questionnaire -39 (PDQ-39) was used to determine quality of life of the patients. Comorbid depression and anxiety were assessed using Inventory of Depressive Symptoms-Self Rated and Hamilton Anxiety Rating Scale. Pearson's correlation and multiple linear regressions were used to analyze relation of sleep quality with quality of life of patients. Fifty patients had poor sleep quality. EDS was present in only 9 patients. Co-morbid depression and anxiety were present in 52 and 34 patients respectively. While the motor severity assessed by UPDRS-III was observed to adversely affect quality of life, it did not negatively impact quality of sleep. Higher score on UPDRS-total and UPDRS IV suggesting advanced disease correlated with poor sleep quality. Depression and anxiety were significantly more frequent in patients with poor sleep quality (p<0.01). Patients with poor sleep quality had worse quality of life (r=0.338, p<0.05). Depression and anxiety were also observed to have significant negative impact on quality of life of PD patients (p<0.01). Poor sleep quality was not found to be an independent predictor of quality of life using multiple linear regression analysis. Poor sleep quality along with comorbid depression, anxiety and advanced stage of disease is associated with poor quality of life. Copyright © 2016 Elsevier B.V. All rights reserved.

    COPD is a complex condition with a heavy burden of disease. Many multidimensional tools have been studied for their prognostic utility but none has been universally adopted as each has its own limitations. We hypothesize that a multidimensional tool examining four domains, health-related quality of life, disease severity, systemic effects of disease and patient factors, would better categorize and prognosticate these patients. We first evaluated 300 patients and found four factors that predicted mortality: BMI, airflow obstruction, St George's Respiratory Questionnaire and age (BOSA). A 10-point index (BOSA index) was constructed and prospectively validated in a cohort of 772 patients with all-cause mortality as the primary outcome. Patients were categorized into their respective BOSA quartile group based on their BOSA score. Multivariate survival analyses and receiver operator characteristic (ROC) curves were used to assess the BOSA index. Patients in BOSA Group 4 were at higher risk of death compared with their counterparts in Group 1 (hazard ratio (HR): 0.29, 95% CI: 0.16-0.51, P < 0.001) and Group 2 (HR: 0.53, 95% CI: 0.34-0.82, P = 0.005). Race and gender did not affect mortality. The area under the ROC curve for BOSA index was 0.690 ± 0.025 while that for Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2011 was 0.641 ± 0.025 (P = 0.17). The BOSA index predicts mortality well and it has at least similar prognostic utility as GOLD 2011 in Asian patients. The BOSA index is a simple tool that does not require complex equipment or testing. It has the potential to be used widely. © 2016 Asian Pacific Society of Respirology.

    To develop and validate a shortened version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). A secondary aim was to compare baseline risk factors predicting health-related quality of life (HRQoL) in children newly diagnosed with epilepsy, as identified using the original and shortened version. Data came from the Health-Related Quality of Life in Children with Epilepsy Study (HERQULES, N = 373), a multicenter prospective cohort study. Principal component analysis reduced the number of items from the original QOLCE, and factor analysis was used to assess the factor structure of the shortened version. Convergent and divergent validity was assessed by correlating the Child Health Questionnaire (CHQ) with the shortened QOLCE. Multiple regression identified risk factors at diagnosis for HRQoL at 24 months. A four-factor, higher-order, 55-item solution was obtained. A total of 21 items were removed. The final model represents functioning in four dimensions of HRQoL: Cognitive, Emotional, Social, and Physical. The shortened QOLCE demonstrated acceptable fit: Bentler's Comparative Fit Index = 0.944; Tucker-Lewis Index = 0.942; root mean square approximation = 0.058 (90% CI: 0.056-0.061); weighted root mean square residuals (WRMR) = 1.582, and excellent internal consistency (α = 0.96, subscales α > 0.80). Factor loadings were good (first-order: λ = 0.66-0.93; higher-order λ = 0.66-0.85; p < 0.001 for all). The shortened QOLCE scores correlated strongly with similar subscales of the Child Health Questionnaire (ρ = 0.38-0.70) while correlating weakly with dissimilar subscales (ρ = 0.30-0.31). While controlling for HRQoL at diagnosis, predictors for better HRQoL at 24 months were the following: no cognitive problems reported (p = 0.001), better family functioning (p = 0.014), fewer family demands (p = 0.008), with an interaction between baseline HRQoL and cognitive problems (p = 0.011).

To develop a new questionnaire to assess the impact of work-related psychological distress and to validate it by testing its factorial structure, its content, its construct and discriminant validity. After critically reviewing the literature, we generated an initial item set to identify the items to be used in a preliminary version of the questionnaire, and then used a focus group to test the comprehensibility of the items. The questionnaire was administered to 329 subjects working in state and private organisation and a small sample of 29 subjects complaining of vexation at work. The Maugeri Stress Index (MSI) is reliable (Cronbach alpha: 0.93). Factorial analysis indicated five factors: Well-being, Adaptation, Support, Irritability and Avoidance. The total and subscale scores were significantly different when comparing subjects with and without vexation at work. The MSI has a multi-factorial structure, good internal reliability and sufficient discriminant power.

    Assessing quality of life, functional outcome, and pain has become important in assessing the effectiveness of treatment for metastatic spine disease. Many questionnaires are able to measure these outcomes; few are validated in patients with metastatic spine disease. As a result, there is no consensus on the ideal questionnaire to use in these patients. Our study aim was to assess whether certain questionnaires measuring quality of life, functional outcome, and pain (1) correlated with each other, (2) measured the construct they claim to measure, (3) had good coverage-floor and ceiling effects, (4) were reliable, and (5) whether there were differences in completion time between them. This is a prospective cross-sectional survey study from three outpatient clinics (two orthopedic oncology clinics and one neurosurgery clinic) from two affiliated tertiary hospital care centers. We included 100 consecutive patients with metastatic spine disease between July 2014 and February 2016. We excluded non-English-speaking patients. The following questionnaires were given in random order: Oswestry Disability Index (ODI) or Neck Disability Index (NDI), Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function, PROMIS Pain Intensity, EuroQol-5 Dimensions (EQ-5D), and the Spine Oncology Study Group Outcome Questionnaire (SOSG-OQ). We used exploratory factor analysis-correlating questionnaires with an underlying mathematically derived trait-to assess if questionnaires measured the same concept. Coverage was assessed by floor and ceiling effects, and reliability was assessed by standard error of measurement as a function of ability. Differences in completion times were tested using the Friedman test. Questionnaires measured the construct they were developed for, as demonstrated with high correlations (>0.7) with the underlying trait. A floor effect was present in the PROMIS Pain Intensity (7.0%), ODI or NDI (4.0%), and the PROMIS Physical Function (1

    Sleep disturbances are common in rheumatoid arthritis (RA) patients and contribute to loss of life quality. To study associations of sleep quality with pain, depression and disease activity in RA. This is a transversal observational study of 112 RA patients submitted to measurement of DAS-28, Epworth scale for daily sleepiness, index of sleep quality by Pittsburg index, risk of sleep apnea by the Berlin questionnaire and degree of depression by the CES-D (Center for Epidemiologic Studies Depression scale) questionnaire. We also collected epidemiological, clinical, serological and treatment data. Only 18.5% of RA patients had sleep of good quality. In univariate analysis a bad sleep measured by Pittsburg index was associated with daily doses of prednisone (p=0.03), DAS-28 (p=0.01), CES-D (p=0.0005) and showed a tendency to be associated with Berlin sleep apnea questionnaire (p=0.06). In multivariate analysis only depression (p=0.008) and Berlin sleep apnea questionnaire (p=0.004) kept this association. Most of RA patients do not have a good sleep quality. Depression and risk of sleep apnea are independently associated with sleep impairment. Copyright © 2016 Elsevier Editora Ltda. All rights reserved.

    This study was conducted to (1) compare diet quality among depressed and nondepressed overweight and obese rural-dwelling adults and (2) determine whether body mass index (BMI) category moderates the relationship between depressive symptoms and overall diet quality. Rural adults in Kentucky (n = 907) completed the 9-item Patient Health Questionnaire (PHQ-9) that assessed depressive symptoms and a food frequency questionnaire that generated 2005 Healthy Eating Index (HEI) scores. Participants were grouped into overweight (BMI 25-29.9 kg/m 2 ) and obese (≥30 kg/m 2 ), and nondepressed (PHQ-9 < 10) and depressed (PHQ-9 ≥ 10) groups. Bootstrapped ANCOVAs were used to compare diet quality among the 4 groups. Ordinary least-squares regression using PROCESS was used to determine whether BMI category (overweight vs obese) moderated the association between depressive symptoms and overall diet quality. Overall diet quality was poorer in the obese depressed group than in the obese nondepressed group. Intake of fruit and dark green/orange vegetables and legumes was lower in the obese depressed group than in the overweight nondepressed group. Depressive symptoms predicted poor overall diet quality (B = -0.287, P < .001) and the relationship was moderated by BMI category (coefficient of BMI category * depressive symptom interaction term = 0.355, P < .049). A significant inverse relationship between depressive symptoms and overall diet quality was observed in the overweight group but not in the obese group. Components of diet quality vary according to BMI category and depressive symptom status. The relationship between depressive symptoms and diet quality is influenced by BMI category. © 2017 National Rural Health Association.

    Health-related quality of life (HRQoL) has been positioned as one of the major endpoints in oncology. Thus, there is a need to validate cancer-site specific survey instruments. This study aimed to perform a transcultural adaptation of the 50-item Expanded Prostate cancer Index Composite (EPIC) questionnaire for HRQoL in prostate cancer patients and to validate the psychometric properties of the French-language version. The EPIC questionnaire measures urinary, bowel, sexual and hormonal domains. The first step, corresponding to transcultural adaptation of the original English version of the EPIC was performed according to the back translation technique. The second step, comprising the validation of the psychometric properties of the EPIC questionnaire, was performed in patients under treatment for localized prostate cancer (treatment group) and in patients cured of prostate cancer (cured group). The EORTC QLQ-C30 and QLQ-PR25 prostate cancer module were also completed by patients to assess criterion validity. Two assessments were performed, i.e., before and at the end of treatment for the Treatment group, to assess sensitivity to change; and at 2 weeks' interval in the Cured group to assess test-retest reliability. Psychometric properties were explored according to classical test theory. The first step showed overall good acceptability and understanding of the questionnaire. In the second step, 215 patients were included from January 2012 to June 2014: 125 in the Treatment group, and 90 in the Cured group. All domains exhibited good internal consistency, except the bowel domain (Cronbach's α = 0.61). No floor effect was observed. Test-retest reliability assessed in the cured group was acceptable, expect for bowel function (intraclass coefficient = 0.68). Criterion validity was good for each domain and subscale. Construct validity was not demonstrated for the hormonal and bowel domains. Sensitivity to change was exhibited for 5/8 subscales and 2/4 summary

    The quality of life assessment means investigating how patients perceive their disease. Malnutrition-specific characteristics make patients more vulnerable, so it is important to know how these factors impact on patients' daily life. To assess the quality of life in malnourished patients who have had hospital admission, and to determine the relationship of the quality of life with age, body mass index, diagnosis of malnutrition, and dependency. Multicenter transversal descriptive study in 106 malnourished patients after hospital admission. The quality of life (SF-12 questionnaire), BMI, functional independency (Barthel index), morbidity, and a dietary intake evaluation were assessed. The relationship between variables was tested by using the Spearman correlation coefficient. The patients of the present study showed a SF-12 mean of 38.32 points. The age was significantly correlated with the SF-12 (r= -0.320, p= 0.001). The BMI was correlated with the SF-12 (r= 0.251, p= 0.011) and its mental component (r= 0.289, p= 0.03). It was also reported a significant correlation between the Barthel index and the SF-12 (r= 0.370, p< 0.001). The general health perception in malnourished patients who have had a hospital admission was lower than the Spanish mean. Moreover, the quality of life in these patients is significantly correlated with age, BMI and functional independency. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

    There are numerous analytical methods that can be utilized in a compounding pharmacy for a quality-assurance program. Since the index of refraction of a liquid/solution is a physical constant, it can be used to assist in identification of a substance, establish its purity, and, in some instances, to determine the concentration of an analyte in solution. This article serves as an introduction to refractive index and some applications of its use in a compounding program.

    Measuring quality of life through questionnaires is a common method to evaluate the impact of different afflictions on the patient's well-being, especially in the field of dermatology where appearance changing afflictions are common. A variety of questionnaires has been used to distinguish different skin conditions like psoriasis, atopic dermatitis and scars. Using the Dermatology Life Quality Index (DLQI), we investigated different scar types regarding their impact on quality of life. We assessed the quality of life in 130 patients presenting to our outpatient scar clinic for the first time using the DLQI. Scars were analysed according to their clinical appearance (physiological scars, keloids, hypertrophic scars, atrophic scars, self-harm scars). Physiological scars were established as a baseline for further comparison between groups. Patients in the physiological scar group scored a mean DLQI score of 2.07 ± 3.56, patients in the keloid-, hypertrophic scar-, atrophic scar- and self-harm scar group scored values of 6.06 ± 4.00, 2.53 ± 2.48, 7.26 ± 6.72 and 12.00 ± 3.85 respectively. When compared to the baseline group the difference in the overall score for keloids was +3.99 (P < 0.001), hypertrophic scars scored +0.45 (ns), atrophic scars +5.19 (P < 0.01) and self-harm scars +9.93 (P < 0.001). Using the DLQI, we could demonstrate that different subsets of pathological scars do affect patients in a different magnitude. The DLQI provides a promising adjunct for quantifying the quality of life in patients suffering from keloids, atrophic- and self-harm scars and may constitute an interesting additional tool for monitoring the progress of scar treatments. © 2015 European Academy of Dermatology and Venereology.

    The purpose of this study was to document the frequency of sleep problems including poor sleep quality, excessive daytime sleepiness, and insomnia in subjects with epilepsy compared with healthy controls and to determine the factors associated with these sleep disturbances. We recruited 180 patients with epilepsy (age: 43.2 ± 15.6 years, men: 50.0%) and 2836 healthy subjects (age: 44.5 ± 15.0 years, men: 49.8%). Sleep and the anxiety/mood profiles were measured using the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Insomnia Severity Index, Goldberg Anxiety Scale, and Patient Health Questionnaire-9 depression scale. Associations of sleep problems with epilepsy and other factors were tested by multiple logistic regression analysis, adjusted for age, gender, body mass index, alcohol intake, smoking, perceived sleep insufficiency, and habitual snoring. Sleep disturbances were more common in the group with epilepsy than in the controls (53.3% vs. 25.5%; p<0.001). Poor sleep quality, excessive daytime sleepiness, and insomnia were significantly associated with epilepsy (odds ratio [95% confidence interval]: 3.52 [2.45-5.05], 2.10 [1.41-3.12], 5.91 [3.43-10.16], respectively). Depressive mood, anxiety, and perceived sleep insufficiency contributed to the presence of sleep disturbances. In the group with epilepsy, seizure remission for the past year related to a lower frequency of insomnia, whereas age, sex, type of epilepsy, and number of antiepileptic drugs were not correlated with sleep problems. Epilepsy was significantly associated with the higher frequency of sleep disturbances, which supports the importance of screening sleep problems in patients with epilepsy and providing available intervention.

    The assessment of impact and evaluation of treatment effects in chronic otitis media (OM) calls for a much broader approach than just examining the presence of middle ear effusion or hearing loss. It is increasingly recognised that this condition may result in a comprised quality of life. Several studies have used proxy completed questionnaires to objectify the illness experience associated with chronic OM. To review questionnaires which have been developed to describe the effects of chronic OM on the daily functioning of children. Psychometric properties have been evaluated, in addition to discriminative and evaluative qualities. A systematic review of publications pertaining to developed questionnaires related with chronic OM. Systematic literature searches of PubMed (1966-January 2007) and EMBASE (1989-January 2007) were conducted, supplemented by using free text words to identify publications after January 2005. The included 15 questionnaires were developed for children with recurrent or persistent OM, describing functional health status (FHS), while two questionnaires also evaluate the effect of tympanostomy tubes insertion. The questionnaires generally cover six impact areas (physical symptoms, child development, educational performance, emotional/practical burden and general health status) with physical symptoms being the most prominant. The OM8-30, OMO-22 and OM-6 adequately reflect the multidimensional aspects of FHS in chronic OM. The OMO-22 and OM8-30 show the best psychometric properties for the discrimination of impact severity between children, while the OM-6 was found to have the best qualities for the evaluation of clinical change. Clinical applicability is crucial for the assessment of FHS in chronic OM, but requires a trade-off with necessary psychometric properties.

    This study aims to develop a motion sickness measurement index in a virtual reality (VR) environment. The VR market is in an early stage of market formation and technological development, and thus, research on the side effects of VR devices such as simulator motion sickness is lacking. In this study, we used the simulator sickness questionnaire (SSQ), which has been traditionally used for simulator motion sickness measurement. To measure the motion sickness in a VR environment, 24 users performed target selection tasks using a VR device. The SSQ was administered immediately after each task, and the order of work was determined using the Latin square design. The existing SSQ was revised to develop a VR sickness questionnaire, which is used as the measurement index in a VR environment. In addition, the target selection method and button size were found to be significant factors that affect motion sickness in a VR environment. The results of this study are expected to be used for measuring and designing simulator sickness using VR devices in future studies. Copyright © 2018 Elsevier Ltd. All rights reserved.

    To evaluate the validity and reliability of the Portuguese language version of a work ability index. Cross sectional survey of a sample of 475 workers from an electrical company in the state of Sao Paulo, Southeastern Brazil (spread across ten municipalities in the Campinas area), carried out in 2005. The following aspects of the Brazilian version of the Work Ability Index were evaluated: construct validity, using factorial exploratory analysis, and discriminant capacity, by comparing mean Work Ability Index scores in two groups with different absenteeism levels; criterion validity, by determining the correlation between self-reported health and Work Ability Index score; and reliability, using Cronbach's alpha to determine the internal consistency of the questionnaire. Factorial analysis indicated three factors in the work ability construct: issues pertaining to 'mental resources' (20.6% of the variance), self-perceived work ability (18.9% of the variance), and presence of diseases and health-related limitations (18.4% of the variance). The index was capable of discriminating workers according to levels of absenteeism, identifying a significantly lower (p<0.0001) mean score among subjects with high absenteeism (37.2 points) when compared to those with low absenteeism (42.3 points). Criterion validity analysis showed a correlation between the index and all dimensions of health status analyzed (p<0.0001). Reliability of the index was high, with a Cronbach's alpha of 0.72. The Brazilian version of the Work Ability Index showed satisfactory psychometric properties with respect to construct validity, thus constituting an appropriate option for evaluating work ability in both individual and population-based settings.

    This study conducted a systematic review of the methodological quality of the psychometric evaluation process and the quality of measurement properties of rheumatoid arthritis (RA)-specific health-related quality-of-life (HRQOL) questionnaires with the purpose of obtaining the best evidence to help in the selection of the most appropriate instrument for measuring HRQOL in RA patients. A systematic literature search was performed to identify RA-specific HRQOL questionnaires in databases. The methodological quality of the studies was assessed using the Consensus-based Standards for the Selection of Health Measurement Instruments checklist. The quality of the measurement properties was assessed using quality criteria. The evidence regarding the measurement properties was pooled using best-evidence synthesis, with considerations of the number and methodological quality of the studies, and the consistency of their findings in terms of the quality of the measurement properties. The search identified 37 studies describing 9 instruments. Best-evidence synthesis suggested that the Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire had the strongest positive evidence, especially with respect to reliability, measurement error, and content validity, and moderate positive evidence with respect to hypothesis testing and responsiveness. The current evidence suggests that the best-validated instrument among the RA-specific HRQOL measures is the RAQoL questionnaire in terms of both methodological quality in the process of psychometric evaluation and the quality of the measurement properties. However, there is limited evidence regarding internal consistency and structural validity of the RAQoL. Further efforts are warranted to establish the psychometric quality of this questionnaire.

    The physical quality index (QI) of radiological devices summarises in a single numerical value between 0 and 1 the results of constancy tests. The aim of this paper is to illustrate the results of the use of such an index on all public radiological devices in the Livorno province over one year. The quality index was calculated for 82 radiological devices of a wide range of types by implementing its algorithm in a spreadsheet-based software for the automatic handling of quality control data. The distribution of quality index values was computed together with the associated statistical quantities. This distribution is strongly asymmetrical, with a sharp peak near the highest QI values. The mean quality index values for the different types of device show some inhomogeneity: in particular, mammography and panoramic dental radiography devices show far lower quality than other devices. In addition, our analysis has identified the parameters that most frequently do not pass the quality tests for each type of device. Finally, we sought some correlation between quality and age of the device, but this was poorly significant. The quality index proved to be a useful tool providing an overview of the physical conditions of radiological devices. By selecting adequate QI threshold values for, it also helps to decide whether a given device should be upgraded or replaced. The identification of critical parameters for each type of device may be used to improve the definition of the QI by attributing greater weights to critical parameters, so as to better address the maintenance of radiological devices.

    In this study the reliability and validity of generic and disease-specific questionnaires has been assessed focusing on responsiveness. This is part of a study on the effects of recurrent acute otitis media (rAOM) on functional health status (FHS) and health-related quality of life (HRQoL) in 383 children with rAOM participating in a randomized clinical trial. The following generic questionnaires were studied: 1. RAND general health rating index, 2. Functional Status Questionnaire (FSQ Generic and FSQ Specific), 3. TNO-AZL Infant Quality of Life (TAIQOL), and the following disease-specific questionnaires: 1. Otitis Media-6 (OM-6), 2. Numerical rating scales (NRS) for child and caregiver (NRS Child and NRS Caregiver), and 3. a new Family Functioning Questionnaire (FFQ). Reliability was good to excellent (Cronbach’s α range 0.80–0.90, intraclass correlation coefficient range 0.76–0.93). Moderate to strong correlations were found between the questionnaires as well as between questionnaires and relevant clinical indicators (r = 0.29–0.49), demonstrating construct validity. Discriminant validity for children with few versus frequent episodes of acute otitis media per year was good for most questionnaires (P < 0.004) but poor for the otitis media-related subscales of the TAIQOL (P = 0.10–0.97) and both NRS (P = 0.22 and 0.48). Except for the TAIQOL subscales, change scores were significant (P < 0.003) for generic and disease-specific questionnaires. Effect sizes were somewhat higher for disease-specific compared to generic questionnaires (0.55–0.95 versus 0.32–0.60) except for the TAIQOL subscales, which showed very poor sensitivity to change. Anchor-based methods resulted in a somewhat larger range of estimates of MCID than distribution-based methods. Combining distribution-based and anchor-based methods resulted in similar ranges for the minimally clinical important differences for generic and disease-specific questionnaires: 2–15 points on a

    We aimed to simplify information from food frequency questionnaires (FFQs) in a single parameter that allows for rapid identification of quality of patient diet and its relationship to cardiovascular risk and pulse wave velocity (PWV). The sample from the EVIDENT study, consisting of 1553 subjects (aged 20-80 years) with no cardiovascular disease selected by random sampling among those attending primary care clinics, was used. The EVIDENT diet index (range 0-100) was calculated based on the results of a FFQ. Evaluation of dietary habits also included adherence to the Mediterranean diet (MD). Cardiovascular risk was estimated, and carotid-femoral pulse wave velocity was measured. Mean subject age was 54.9 ± 13.8 years, and 60.3% of subjects were female. The mean value of the EVIDENT diet index was 52.1 ± 3.2 points. Subjects in the third tertile (the highest score) had the greatest adherence to MD and the highest energy intake, with greater amounts of carbohydrates, protein, and fiber. The best cut-off point of the EVIDENT diet index for predicting good adherence to the MD is 52.3 (0.71 sensitivity, 0.61 specificity). In a multiple regression analysis, after a complete adjustment, it was estimated that for each one-point increase in the EVIDENT diet index, cardiovascular risk (CVR), blood-pressure, waist circumference, and PWV decreased by 0.14, 0.43, 0.24, and 0.09 respectively (p < 0.05, all). The diet quality index developed is associated to CVR and its components, and also with arterial stiffness, as measured with PWV. This index is also a good predictor of adherence to MD.

    The quality standards of the Dutch Society of Intensive Care require monitoring of the satisfaction of patient's relatives with respect to care. Currently, no suitable instrument is available in the Netherlands to measure this. This study describes the development and psychometric evaluation of the questionnaire-based Consumer Quality Index 'Relatives in Intensive Care Unit' (CQI 'R-ICU'). The CQI 'R-ICU' measures the perceived quality of care from the perspective of patients' relatives, and identifies aspects of care that need improvement. The CQI 'R-ICU' was developed using a mixed method design. Items were based on quality of care aspects from earlier studies and from focus group interviews with patients' relatives. The time period for the data collection of the psychometric evaluation was from October 2011 until July 2012. Relatives of adult intensive care patients in one university hospital and five general hospitals in the Netherlands were approached to participate. Psychometric evaluation included item analysis, inter-item analysis, and factor analysis. Twelve aspects were noted as being indicators of quality of care, and were subsequently selected for the questionnaire's vocabulary. The response rate of patients' relatives was 81% (n = 455). Quality of care was represented by two clusters, each showing a high reliability: 'Communication' (α = .80) and 'Participation' (α = .84). Relatives ranked the following aspects for quality of care as most important: no conflicting information, information from doctors and nurses is comprehensive, and health professionals take patients' relatives seriously. The least important care aspects were: need for contact with peers, nuisance, and contact with a spiritual counsellor. Aspects that needed the most urgent improvement (highest quality improvement scores) were: information about how relatives can contribute to the care of the patient, information about the use of meal-facilities in the hospital, and

    A new plan quality index integrating dosimetric and radiobiological indices was proposed to facilitate the evaluation and comparison of simultaneous integrated boost (SIB) intensity modulated radiotherapy (IMRT) plans for nasopharyngeal cancer (NPC) patients. Ten NPC patients treated by SIB-IMRT were enrolled in the study. Custom software was developed to read dose-volume histogram (DVH) curves from the treatment planning system (TPS). A plan filtering matrix was introduced to filter plans that fail to satisfy treatment protocol. Target plan quality indices and organ at risk (OAR) plan quality indices were calculated for qualified plans. A unique composite plan quality index (CPQI) was proposed based on the relative weight of these indices to evaluate and compare competing plans. Plan ranking results were compared with detailed statistical analysis, radiation oncology quality system (ROQS) scoring results and physician's evaluation results to verify the accuracy of this new plan quality index. The average CPQI values for plans with OAR priority of low, normal, high, and PTV only were 0.22 ± 0.08, 0.49 ± 0.077, 0.71 ± 0.062, and -0.21 ± 0.16, respectively. There were significant differences among these plan quality indices (One-way ANOVA test, p < 0.01). This was consistent with statistical analysis, ROQS results and physician's ranking results in which 90% OAR high plans were selected. Plan filtering matrix was able to speed up the plan evaluation process. The new matrix plan quality index CPQI showed good consistence with physician ranking results. It is a promising index for NPC SIB-IMRT plan evaluation. Copyright © 2013 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd. All rights reserved.

    The associations of parental feeding practices and feeding style with childhood obesity have gained more attention in the literature recently; however, fathers are rarely included within these studies. The aim of this research was to determine the relationship of paternal feeding practices on child diet quality, weight status, and eating behavior, and the moderating effect of paternal feeding style on these relationships in preschool age children. This study included a one-time, one-on-one interview with biological fathers of preschoolers (n = 150) to assess feeding practices (Child Feeding Questionnaire), feeding style (Caregiver Feeding Style Questionnaire), child eating behaviors (Child Eating Behavior Questionnaire), and diet quality (24 hour recall, Healthy Eating Index). Height and weight for each father and child were also measured and Body Mass Index (BMI) or BMI z-score calculated. Linear regression was used to test the relationship between paternal feeding practices, style and child diet quality and/or body weight. Overall, the findings revealed that a father's feeding practices and feeding style are not associated with children's diet quality or weight status. However, child eating behaviors are associated with child BMI z-score and these relationships are moderated by paternal feeding practices. For example, child satiety responsiveness is inversely (β = -.421, p = 0.031) associated with child BMI z-score only if paternal restriction scores are high. This relationship is not significant when paternal restriction scores are low (β = -.200, p = 0.448). These results suggest that some child appetitive traits may be related to child weight status when exposed to certain paternal feeding practices. Future studies should consider the inclusion of fathers as their feeding practices and feeding style may be related to a child's eating behavior. Copyright © 2015 Elsevier Ltd. All rights reserved.

    OBJECTIVES--To develop and test a questionnaire for measuring quality of life in patients with Parkinson's disease. METHODS--An item pool was developed based on the experience of patients with Parkinson's disease and of neurologists; medical literature on the problems of patients with Parkinson's disease; and other quality of life questionnaires. To reduce the item pool, 13 patients identified items that were a problem to them and rated their importance. Items which were most often chosen and rated most important were included in the Parkinson's disease quality of life questionnaire (PDQL). The PDQL consists of 37 items. To evaluate the discriminant validity of the PDQL three groups of severity of disease were compared. To test for convergent validity, the scores of the PDQL were tested for correlation with standard indices of quality of life. RESULTS--The PDQL was filled out by 384 patients with Parkinson's disease. It consisted of four subscales: parkinsonian symptoms, systemic symptoms, emotional functioning, and social functioning. The internal-consistency reliability coefficients of the PDQL subscales were high (0.80-0.87). Patients with higher disease severity had significantly lower quality of life on all PDQL subscales (P < 0.05). Almost all PDQL subscales correlated highly (P < 0.001) with the corresponding scales of the standard quality of life indices. CONCLUSION--The PDQL is a relevant, reliable, and valid measure of the quality of life of patients with Parkinson's disease. Images PMID:8676165

  17. Development and validation of a food-based diet quality index for New Zealand adolescents

    PubMed Central

    2013-01-01

    Background As there is no population-specific, simple food-based diet index suitable for examination of diet quality in New Zealand (NZ) adolescents, there is a need to develop such a tool. Therefore, this study aimed to develop an adolescent-specific diet quality index based on dietary information sourced from a Food Questionnaire (FQ) and examine its validity relative to a four-day estimated food record (4DFR) obtained from a group of adolescents aged 14 to 18 years. Methods A diet quality index for NZ adolescents (NZDQI-A) was developed based on ‘Adequacy’ and ‘Variety’ of five food groups reflecting the New Zealand Food and Nutrition Guidelines for Healthy Adolescents. The NZDQI-A was scored from zero to 100, with a higher score reflecting a better diet quality. Forty-one adolescents (16 males, 25 females, aged 14–18 years) each completed the FQ and a 4DFR. The test-retest reliability of the FQ-derived NZDQI-A scores over a two-week period and the relative validity of the scores compared to the 4DFR were estimated using Pearson’s correlations. Construct validity was examined by comparing NZDQI-A scores against nutrient intakes obtained from the 4DFR. Results The NZDQI-A derived from the FQ showed good reliability (r = 0.65) and reasonable agreement with 4DFR in ranking participants by scores (r = 0.39). More than half of the participants were classified into the same thirds of scores while 10% were misclassified into the opposite thirds by the two methods. Higher NZDQI-A scores were also associated with lower total fat and saturated fat intakes and higher iron intakes. Conclusions Higher NZDQI-A scores were associated with more desirable fat and iron intakes. The scores derived from either FQ or 4DFR were comparable and reproducible when repeated within two weeks. The NZDQI-A is relatively valid and reliable in ranking diet quality in adolescents at a group level even in a small sample size. Further studies are required to test the

    Purpose The SLICC Damage Index (SDI) is a validated instrument for assessing organ damage in systemic lupus erythematosus (SLE). Trained physicians must complete it, limiting utility where this is impossible. Methods We developed and pilot-tested a self-assessed organ damage instrument, the Lupus Damage Index Questionnaire (LDIQ), in 37 SLE subjects and 7 physicians. After refinement, 569 English-speaking SLE subjects and 14 rheumatologists from 11 international SLE clinics participated in validation. Subjects and physicians completed instruments separately. We calculated sensitivity, specificity, Spearman correlations and agreement, using the SDI as gold standard. 605 SLE participants in the community-based National Data Bank for Rheumatic Diseases (NDB) study completed the LDIQ and we assessed correlations with outcome and disability measures. Results Mean LDIQ score was 3.3 (0-16) and mean SDI score was 1.5 (0-9). LDIQ had a moderately high correlation with SDI (Spearman r=0.50, p<0.001). Specificities of individual LDIQ items were >80%, except for neuropathy. Sensitivities were variable and lowest for damage with <1% prevalence. Agreement between SDI and LDIQ was > 85% for all but neuropathy, reduced renal function, deforming arthritis and alopecia. In the NDB, LDIQ correlated well with comorbidity index (r=0.45), SF-36 physical component scale (0.43), Medical Research Council dyspnea scale (0.40), disability (0.37) and SLE Activity Questionnaire score (0.37). Conclusions The LDIQ’s metric properties are good compared to the SDI. It has construct validity and correlations with health assessments similar to the SDI. The LDIQ should allow expansion of SLE research. Its ultimate value will be determined in longitudinal studies. PMID:20391512

    The Mexico City Metropolitan Area has an expansive urban population and a long history of air quality management challenges. Poor air quality has been associated with adverse pulmonary and cardiac health effects, particularly among susceptible populations with underlying disease. In addition to reducing pollution concentrations, risk communication efforts that inform behavior modification have the potential to reduce public health burdens associated with air pollution. This study investigates the utilization of Mexico's IMECA risk communication index to inform air pollution avoidance behavior among the general population living in the Mexico City Metropolitan Area. Individuals were selected via probability sampling and surveyed by phone about their air quality index knowledge, pollution concerns, and individual behaviors. The results indicated reasonably high awareness of the air quality index (53% of respondents), with greater awareness in urban areas, among older and more educated individuals, and for those who received air quality information from a healthcare provider. Additionally, behavior modification was less influenced by index reports as it was by personal perceptions of air quality, and there was no difference in behavior modification among susceptible and non-susceptible groups. Taken together, these results suggest there are opportunities to improve the public health impact of risk communication through an increased focus on susceptible populations and greater encouragement of public action in response to local air quality indices.

    The Menopause-Specific Quality-of-Life (MENQOL) questionnaire was developed as a specific tool to measure the health-related quality-of-life of postmenopausal women. Thus far, the Chinese version questionnaire has not been subjected to psychometric assessment with a large sample. This study aims to evaluate the validity and reliability of the Chinese version of the MENQOL specific to postmenopausal women in China. A total of 1,137 menopausal symptomatic and 491 menopausal asymptomatic women from eight cities in China were recruited using a convenience sampling method. Psychometric properties were evaluated by descriptive statistics, validity, and reliability. Reliability was assessed for each subscale of the MENQOL through internal consistency reliability with Cronbach's α and intersubscale correlations. Item-domain correlations, principal components analysis (PCA), and confirmatory factor analysis were performed to determine construct validity. t tests were used to compare the differences between the menopausal symptomatic and asymptomatic women and to evaluate the discriminate validity. Pearson correlation coefficients were calculated between MENQOL scores and the Kupperman index to assess criterion-related validity. The most common symptoms in Chinese menopausal symptomatic women were "experiencing poor memory" (94.4%), "feeling tired or worn out" (93.8%), "aching in muscle and joints" (89.4%), "low backache" (86.9%), "decrease in physical strength" (86.6%), "aches in back of neck or head" (86.2%), "difficulty sleeping" (83.6%), "accomplishing less than I used to" (83.4%), "feeling a lack of energy" (83.3%), "change in your sexual desire" (81%), and "hot flash" (80.7%) among others. The symptoms of "increased facial hair" were rarely seen (9.9%). The vasomotor domain, as well as psychosocial, physical, and sexual domains showed high reliability (Cronbach's α 0.84, 0.87, 0.89, and 0.86, respectively).

    A better estimate of overall environmental quality is needed to improve our understanding of the relationship between environmental conditions and humanhealth. Described in this report is the effort to construct an environmental quality index representing multiple domains of the ambient environment, includingair, water, land, built and sociodemographic for all counties in the U.S. for the time period including the years 2000-2005. The EQI was created for two mainpurposes: a.) as an indicator of ambient conditions/exposure in environmental health modeling and b.) as a covariate to adjust for ambient conditions inenvironmental models. However, as detailed in the discussion of this report, the EQI can be adapted and used for other objectives. The EQI was developedin four parts: domain identification; data source identification and review; variable construction; and data reduction. Each of these four areas represents achapter in the report where detailed information is provided on the development of the EQI. The methods applied provide a reproducible approach thatcapitalizes almost exclusively on publically-available data sources.This report is written as an overview to the companion technical document.

    Our recent review of the literature uncovered eleven obesity-specific quality of life questionnaires, all with incomplete demonstration of their measurement properties. Our objective was to validate a new self-administered questionnaire specific to morbid obesity to be used in clinical trials. The study was carried out at the bariatric surgery clinic of Laval Hospital, Quebec City, Canada. This study followed our description of health-related quality of life in morbid obesity from which we constructed the Laval Questionnaire. Its construct validity and responsiveness were tested by comparing the baseline and changes at 1-year follow-up in 6 domain scores (symptoms, activity/mobility, personal hygiene/clothing, emotions, social interactions, sexual life) with those of questionnaires measuring related constructs (SF-36, Impact of Weight on Quality of Life-Lite, Rosenberg Self-Esteem Scale and Beck Depression Inventory-II). 112 patients (67 who got bariatric surgery, 45 who remained on the waiting list during the study period) participated in this study. The analysis of the discriminative function of the questionnaire showed moderate-to-high correlations between the scores in each domain of our instrument and the corresponding questionnaires. The analysis of its evaluative function showed (1) significant differences in score changes between patients with bariatric surgery and those without, and (2) moderate-to-high correlations between the changes in scores in the new instrument and the changes in the corresponding questionnaires. Most of these correlations met the a priori predictions we had made regarding their direction and magnitude. The Laval Questionnaire is a valid measure of health-related quality of life in patients with morbid obesity and is responsive to treatment-induced changes.

    Two methods of measuring physical activity (PA) were compared over a consecutive 7-day period among 25 adults (12 men and 13 women). Each day estimates of energy expended in light, moderate, vigorous, and total PA were derived from the simultaneous heart-rate motion sensor (HR+M) technique. At the end of the 7-day period participants completed the College Alumnus Questionnaire Physical Activity Index (CAQ-PAI) and results were compared with HR+M technique estimates. Correlations between the two methods in the four activity categories ranged from r=0.20 to r=0.47, with vigorous and total PA showing higher associations than light and moderate PA. Mean levels of PA (MET-minxwk(-1)) obtained using the two methods were similar in the moderate and vigorous categories, but individual differences were large. Energy expended in light PA was significantly underestimated on the CAQ-PAI, resulting in lower total activity scores on this questionnaire as compared with the HR+M. The CAQ-PAI accurately reflected mean moderate and vigorous activity in comparison with the HR+M technique. The results are consistent with other studies which have shown that physical activity questionnaires are better at assessing vigorous PA than ubiquitous light-moderate activities.

    The aim of this study was to develop a total quality index and examine the effects of modified atmosphere packaging (MAP) on the quality of Agaricus bisporus mushrooms stored for 22 days at 4 °C. Mushrooms were packaged under three MAPs: high nitrogen packaging (HNP), low carbon dioxide packaging (LCP) and low oxygen packaging (LOP). Passive MAP with air inside initially was used as the atmosphere treatment (AIR). This research revealed two phases in quality deterioration of A. bisporus mushrooms. During the first week, most of the quality parameters were not statistically different. Thereafter, odor intensities were stronger for all four types of packaging. Color difference and browning index values showed significantly lower color changes for AIR and LOP compared with HNP and LCP mushrooms. The best total quality index was calculated for LOP, followed by LCP and AIR. The findings of this study are useful with respect to examining two-component MAPs, separating the limiting factors (O 2 and CO 2 ) and evaluating quality deterioration effects and the total quality index of A. bisporus mushrooms. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    The aim of this study was to develop and validate a brief version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). A secondary aim was to compare the results described in previously published studies using the QOLCE-55 with those obtained using the new brief version. Data come from 373 children involved in the Health-related Quality of Life in Children with Epilepsy Study, a multicenter prospective cohort study. Item response theory (IRT) methods were used to assess dimensionality and item properties and to guide the selection of items. Replication of results using the brief measure was conducted with multiple regression, multinomial regression, and latent mixture modeling techniques. IRT methods identified a bi-factor graded response model that best fits the data. Thirty-nine items were removed, resulting in a 16-item QOLCE (QOLCE-16) with an equal number of items in all 4 domains of functioning (Cognitive, Emotional, Social, and Physical). Model fit was excellent: Comparative Fit Index = 0.99; Tucker-Lewis Index = 0.99; root mean square error of approximation = 0.052 (90% confidence interval [CI] 0.041-0.064); weighted root mean square = 0.76. Results that were reported previously using the QOLCE-55 and QOLCE-76 were comparable to those generated using the QOLCE-16. The QOLCE-16 is a multidimensional measure of health-related quality of life (HRQoL) with good psychometric properties and a short-estimated completion time. It is notable that the items were calibrated using multidimensional IRT methods to create a measure that conforms to conventional definitions of HRQoL. The QOLCE-16 is an appropriate measure for both clinicians and researchers wanting to record HRQoL information in children with epilepsy.

    Family Dermatology Life Quality Index (FDLQI) is an instrument for assessing the quality of life of family members of dermatologic patients. The aim of this study was to describe the cultural adaptation of this questionnaire and to assess psychometric properties of the Persian version. At first, the questionnaire was translated into Persian, and then back-translation was performed. The whole cycle was repeated until a consensus was reached about the optimal translation. In the next step, cognitive debriefing was performed, and after approval of the Persian version by FDLQI developers, it was distributed among 100 family members of dermatological patients in order to evaluate its validity and reliability. Mean age of participants was 37.1 years (±12.3). Mean score of FDLQI was 15.4 (±5.5) with maximum and minimum scores of 30 and 6, respectively. The quality of life of studied participants showed no significant difference based on age-group, sex, educational level and the family relationship. Cronbach's alpha was calculated as 0.87. Exploratory factor analysis revealed a one-factor solution that accounted for 40.7 % of the variance. The unidimensional model was supported by confirmatory factor analysis. The results of the present study showed that the Persian version of FDLQI has acceptable factorial validity and internal consistency reliability.

    The overall goal of the WHO Healthy Cities Project was to translate some key points of the Ottawa Charter for Health Promotion (1986) into reality such as public health policies, creating health-promoting environments, strengthening community action through active public participation (empowerment of communities) and equity in health at the local level. These should be anchored within the local political administrative system (PAS), which means health should be on the agenda of policymakers in all sectors. To figure out how far this has been attained after almost 15 years of "healthy cities" policy in Germany was the focal point of the first questioning of local project coordinators. A written questionnaire containing 128 items has been developed in collaboration with the Healthy Cities Network-Coordinator. The questionnaire consists of 78 standardised questions and some (23) open-ended questions for more specific qualitative information. Also included are 27 ten-point rating scales to evaluate the coordinators' view of some aspects of their healthy cities work and to assess its progress. Based on 30 questions of the questionnaire we generated six quality indices, summarised to a quality index for a monitoring model. 47 (90 %) project-coordinators from a list of 52 took part in the first German Healthy Cities survey in the spring 2002. Selected results of the network questioning concerning the local "healthy cities" offices, work priorities and methods demonstrate differences between East and West Germany and general weakpoints of the "healthy cities" projects. Data analysis based on six quality dimensions of the "Healthy Cities" work, Programme Equipment and Commitment (Structure), Concept Quality and Integration within the Network (Process), Self-reported Success and Integration within the City/Municipality (Outcome), revealed some weak points of the " Healthy Cities" work as follows: Basing on the six quality dimensions we present a monitoring model (Healthy

    Define and establish the reference values of the CAVIPRES-30 Questionnaire, a health related quality of life questionnaire specific for prostate cancer patients. The CAVIPRES-30 was administered to 2,630 males with prostate cancer included by 238 Urologist belonging to the Spanish National Healthcare System. Descriptive analysis on socio-demographic and clinical data were performed, and multivariate analyses were used to corroborate that stratification variables were statistically significantly and independently associated to the overall score of the questionnaire. The variables Time since diagnosis of the illness, whether the patient had a Stable partner or not, if he was, or not, undergoing Symptomatic treatment were statistically significantly and independently associated (P < .001) to the overall score of the questionnaire. The reference values table of the CAVIPRES-30 questionnaire is made up of different kinds of information of each patient profile: sample size, descriptive statistics with regard to the overall score, Cronbach's alpha value (between .791 and .875) and the questionnaire's values are reported by deciles. The results of this study contribute new proof as to the suitability and usefulness of the CAVIPRES-30 questionnaire as an instrument for assessing individually the quality of life of prostate cancer.

    To assess the psychometric properties of the Carers Quality of Life Questionnaire for Parkinsonism using a Rasch modeling approach and determine the optimal cut-off score. We performed a Rasch analysis of the survey answers of 430 carers of patients with atypical parkinsonism. All of the scale items demonstrated acceptable goodness of fit to the Rasch model. The scale was unidimensional and no notable differential item functioning was detected in the items regarding age and disease type. Rating categories were functioning adequately in all scale items. The scale had high reliability (.95) and construct validity and a high degree of precision, distinguishing between 5 distinct groups of carers with different levels of quality of life. A cut-off score of 62 was found to have the optimal screening accuracy based on Hospital Anxiety and Depression Scale subscores. The results suggest that the Carers Quality of Life Questionnaire for Parkinsonism is a useful scale to assess carers' quality of life and allows analyses requiring interval scaling of variables. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

    The daily press is an important source of health information and may influence health care utilization. However, medical reports published in newspapers from developed countries have shown a poor quality. The reliability of the questionnaire Index of Scientific Quality was evaluated by using it to measure the scientific quality of health information published by Argentinian newspapers between 2000 and 2002. It assessed the readability of the texts in grade levels and explored the relationship between quality and other factors. The Spanish adaptation of the instrument consisted in translation, back-traslation and pilot study. The reliability was assessed by applying the instrument to newspaper articles with more than 300 words that discussed therapy, diagnosis, prevention, lifestyle effects, and hazardous exposure. Two physicians independently graded 129 articles. Inter-observer and intra-observer concordance was quantified for each item with the intra-class correlation coefficient (CI95%). To measure scientific quality, a randomized sample of 210 articles was assessed. Each received a mark that ranged from 0 to 100. Readability was determined by the FRY graph method. The relationship between quality and other variables was explored with multiple linear regression analysis. The inter-rater concordance varied between 0.48 (0.34-0.61) and 0.67 (0.56-0.75). Intra-rater concordance varied from 0.51 (0.37-0.63) to 0.95 (0.93-0.96). The internal consistency (Cronbach's alpha) was 0.88. The quality-of-health-information was rated at 25 points (16.7, 33.3) [median (intercuartil range)]. The reading level was assessed to be at the 10.4 grade (10.2-10.6) [mean (CI 95%)]. Quality of the health information was greatly deficient; however, no specific factors were related with quality. Readability was probably a key barrier for access to the health information.

    Ostomies may be performed for bowel or urinary diversion, and occur in both cancer and non-cancer patients. Impact on physical, psychological, social and spiritual well-being is not unexpected, but has been minimally described in the literature. The City of Hope Quality of Life (COH-QOL)-Ostomy Questionnaire is an adult patient self-report instrument designed to assess quality of life. This report focuses on the revision and psychometric testing of this questionnaire. The revised COH-QOL-Ostomy Questionnaire involved in-depth patient interviews and expert panel review. The format consisted of a 13-item disease and demographic section, a 34-item forced-choice section, and a 41-item linear analogue scaled section. A mailed survey to California members of the United Ostomy Association resulted in a 62% response rate (n = 1513). Factor analysis was conducted to refine the instrument. Construct validity involved testing a number of hypotheses identifying contrasting groups. Factor analysis confirmed the conceptual framework. Reliability of subscales ranged from 0.77 to 0.90. The questionnaire discriminated between subpopulations with specific concerns. Overall, the analyses provide evidence for the validity and reliability of the COH-QOL-Ostomy Questionnaire as a comprehensive, multidimensional self-report questionnaire for measuring quality of life in patients with intestinal ostomies.

    This study focused on predicting dyslexia in children ahead of formal literacy training. Because dyslexia is a constitutional impairment, risk factors should be seen in preschool. It was hypothesized that data gathered at age 5 using questions targeting the dyslexia endophenotype should be reliable and valid predictors of dyslexia at age 11. A questionnaire was given to caretakers of 120 5-year-old children, and a risk index score was calculated based on questions regarding health, laterality, motor skills, language, special needs education and heredity. An at-risk group (n = 25) and matched controls (n = 24) were followed until age 11, when a similar questionnaire and literacy tests were administered to the children who participated in the follow-up study (22 at risk and 20 control). Half of the at-risk children and two of the control children at age 5 were identified as having dyslexia at age 11 (8 girls and 5 boys). It is concluded that it is possible to identify children at the age of 5 who will have dyslexia at the age of 11 through a questionnaire approach. Copyright © 2011 John Wiley & Sons, Ltd.

    Abstract. Medical images and videos are now increasingly part of modern telecommunication applications, including telemedicinal applications, favored by advancements in video compression and communication technologies. Medical video quality evaluation is essential for modern applications since compression and transmission processes often compromise the video quality. Several state-of-the-art video quality metrics used for quality evaluation assess the perceptual quality of the video. For a medical video, assessing quality in terms of “diagnostic” value rather than “perceptual” quality is more important. We present a diagnostic-quality–oriented video quality metric for quality evaluation of cardiac ultrasound videos. Cardiac ultrasound videos are characterized by rapid repetitive cardiac motions and distinct structural information characteristics that are explored by the proposed metric. Cardiac ultrasound video quality index, the proposed metric, is a full reference metric and uses the motion and edge information of the cardiac ultrasound video to evaluate the video quality. The metric was evaluated for its performance in approximating the quality of cardiac ultrasound videos by testing its correlation with the subjective scores of medical experts. The results of our tests showed that the metric has high correlation with medical expert opinions and in several cases outperforms the state-of-the-art video quality metrics considered in our tests.

    Developing a water quality index which is used to convert the water quality dataset into a single number is the most important task of most water quality monitoring programmes. As the water quality index setup is based on different local obstacles, it is not feasible to introduce a definite water quality index to reveal the water quality level. In this study, an innovative software application, the Iranian Water Quality Index Software (IWQIS), is presented in order to facilitate calculation of a water quality index based on dynamic weight factors, which will help users to compute the water quality index in cases where some parameters are missing from the datasets. A dataset containing 735 water samples of drinking water quality in different parts of the country was used to show the performance of this software using different criteria parameters. The software proved to be an efficient tool to facilitate the setup of water quality indices based on flexible use of variables and water quality databases.

    The Adult Strabismus Quality of Life Questionnaire (AS-20) and the Amblyopia & Strabismus Questionnaire (A&SQ) both measure health-related quality of life in strabismus patients. We evaluated to what extent these instruments cover similar domains by identifying the underlying quality-of-life factors of the combined questionnaires. Participants were adults from a historic cohort with available orthoptic childhood data documenting strabismus and/or amblyopia. They had previously completed the A&SQ and were now asked to complete the AS-20. Factor analysis was performed on the correlation-matrix of the combined AS-20 and A&SQ data to identify common underlying factors. The identified factors were correlated with the clinical variables of angle of strabismus, degree of binocular vision, and visual acuity of the worse eye. One hundred ten patients completed both questionnaires (mean age, 44 years; range, 38-51 years). Six factors were found that together explained 78% of the total variance. The factor structure was dominated by the first four factors. One factor contained psychosocial and social-contact items, and another factor depth-perception items from both questionnaires. A third factor contained seven items-only from the AS-20-on eye strain, stress, and difficulties with reading and with concentrating. A fourth factor contained seven items-only from the A&SQ-on fear of losing the better eye and visual disorientation, specific for amblyopia. Current visual acuity of the worse eye correlated with depth-perception items and vision-related items, whereas current binocular vision correlated with psychosocial and social-contact items, in 93 patients. Factor analysis suggests that the AS-20 and A&SQ measure a similar psychosocial quality-of-life domain. However, functional problems like avoidance of reading, difficulty in concentrating, eye stress, reading problems, inability to enjoy hobbies, and need for frequent breaks when reading are represented only in the AS-20

    Prescription quality can be a direct predictor of the net outcome of a health care delivery effort. Quality of prescription may be considered as a cumulative matrix of multiple components of a prescription on the basis of their relative importance. Prescription quality index is a recognized tool in clinical medicine for multiple purposes including the prediction of health care intervention outcome. Considering the importance of prescription quality among every system of medicine, an attempt was made to design a prescription quality index for Ayurveda. The Prescription Quality Index for Ayurveda was designed through item selection following a thorough literature search and was validated through multiple peer group discussions. Final draft of index containing 38 individual items carrying different scores as per their importance in the prescription was subjected to a pilot test upon 1576 indoor prescriptions generated in 2015 at State Ayurvedic College Hospital, Lucknow. The study revealed large information gaps in the components of the prescription where it was supposed to be noted by the prescribers. These gaps in the Ayurvedic prescriptions were most significant in the areas pertaining to Ayurvedic fundamentals of clinical examination, disease diagnosis and Ayurvedic drug intake methods. Prescription Quality Index for Ayurveda was found useful in underlining the gaps between the ideal and generated prescriptions. This can be utilized as a useful tool to evaluate the quality of Ayurvedic prescriptions by seeing their adherence to the standard prescription template.

    A composite measure of diet quality is preferable to an index of nutrients, food groups, or health-promoting behaviors in dietary assessment. However, to date, such a tool for Chinese children is lacking. Based on the current Chinese Dietary Guidelines and Dietary Reference Intakes, a dietary index for Chinese school-aged children, the Chinese Children Dietary Index was developed to assess overall diet quality among children in South China. Dietary data were recorded using 24-hour recalls among 1,719 children aged 7 to 15 years between March and June 2013. Inactivity data and sociodemographic information were also collected. The Chinese Children Dietary Index included 16 components, which incorporated nutrients, foods/food groups, and health-promoting behaviors. The range of possible Chinese Children Dietary Index scores was 0 to 160, with a higher score indicating better diet quality. Pearson/Spearman correlation was used to assess relative validity using correlations between total Chinese Children Dietary Index score and age, body mass index (BMI; calculated as kg/m(2)), inactivity, whole-grain intake, frequency of fried-foods intake, nutrient adequacy ratios for energy intake and 12 nutrients not included in the Chinese Children Dietary Index, and the mean adequacy ratio. Finally, a stepwise multiple regression analysis was performed to indicate the factors correlated with Chinese Children Dietary Index. Mean Chinese Children Dietary Index score of this sample was 88.1 points (range=34.2 to 137.8), the Chinese Children Dietary Index score of girls was higher than that of boys and decreased with higher age. Children with higher Chinese Children Dietary Index had lower body mass index and spent less time being inactive. Positive associations were observed between Chinese Children Dietary Index and the majority of nutrient adequacy ratios and the mean adequacy ratio. Age, paternal educational level, and family size were correlated with Chinese Children Dietary

  19. Development of innovative computer software to facilitate the setup and computation of water quality index

    2013-01-01

    Background Developing a water quality index which is used to convert the water quality dataset into a single number is the most important task of most water quality monitoring programmes. As the water quality index setup is based on different local obstacles, it is not feasible to introduce a definite water quality index to reveal the water quality level. Findings In this study, an innovative software application, the Iranian Water Quality Index Software (IWQIS), is presented in order to facilitate calculation of a water quality index based on dynamic weight factors, which will help users to compute the water quality index in cases where some parameters are missing from the datasets. Conclusion A dataset containing 735 water samples of drinking water quality in different parts of the country was used to show the performance of this software using different criteria parameters. The software proved to be an efficient tool to facilitate the setup of water quality indices based on flexible use of variables and water quality databases. PMID:24499556

    Patient satisfaction with teleconsultation services can increase their acceptance. Validated and standardized questionnaires to measure the quality aspects of teleconsultation relevant from the patients' perspective are not available yet. We aim to develop such a questionnaire. First, a systematic literature search was performed and focus groups were held to acquire quality aspects of teleconsultations patients perceive as important. Thirty-seven unique quality aspects distilled from these activities, were used for questionnaire development based on the framework of the Consumer Quality Index. In future research, the comprehensiveness, relevance and unambiguousness of the concept questionnaire need to be tested and the reliability and internal cohesion of the questionnaire assessed.

    In this study scales and items for the Oral Cancer Quality-of-life Questionnaire (QOL-OC) were designed and the instrument was evaluated. The QOL-OC was developed and modified using the international definition of quality of life (QOL) promulgated by the European Organization for Research and Treatment of Cancer (EORTC) and analysis of the precedent measuring instruments. The contents of each item were determined in the context of the specific characteristics of oral cancer. Two hundred thirteen oral cancer patients were asked to complete both the EORTC core quality of life questionnaire (EORTC QLC-C30) and the QOL-OC. Data collected was used to conduct factor analysis, test-retest reliability, internal consistency, and construct validity. Questionnaire compliance was relatively high. Fourteen of the 213 subjects accepted the same tests after 24 to 48 h demonstrating a high test-retest reliability for all five scales. Overall internal consistency surpasses 0.8. The outcome of the factor analysis coincides substantially with our theoretical conception. Each item shows a higher correlation coefficient within its own scale than the others which indicates high construct validity. QOL-OC demonstrates fairly good statistical reliability, validity, and feasibility. However, further tests and modification are needed to ensure its applicability to the quality-of-life assessment of Chinese oral cancer patients.

    2017-04-01

    The goal of this review was to identify, describe, and evaluate the existing multiple sleep disorders screening questionnaires for their comprehensiveness, brevity, and psychometric quality. A systematic review was conducted using Medline/PubMed, cumulative index to nursing & allied health literature, health and psychosocial instruments and the "grey literature". Search terms were "sleep disorders, screening, questionnaires, and psychometrics". The scope of the search was limited to English language articles for adult age groups from 1989 through 2015. Of the n = 2812 articles identified, most were assessment or treatment guideline reviews, topical reviews, and/or empirical articles. Seven of the articles described multiple sleep disorders screening instruments. Of the identified instruments, two questionnaires (the Holland sleep Disorders questionnaire and sleep-50) were evaluated as comprehensive and one questionnaire (the global sleep assessment questionnaire [GSAQ]) was judged to be both comprehensive and efficient. The GSAQ was found to cover four of the six core intrinsic disorders, sleep insufficiency, and daytime sequela with 11 questions. Accordingly, the GSAQ is the most suitable for application as a general sleep disorders screener. Additional work is required to validate this instrument in the context of primary care. Finally, the future development of multiple sleep disorders screening questionnaires should not only cover all six intrinsic sleep disorders but also acquire some basic demographic information (age, sex, body mass index, presence/absence of bed partner, work status and shift) and some limited data regarding sleep sufficiency and the daytime consequences of sleep disturbance.

    Environmental performance strongly deals with the quality of human life. In Indonesia, this performance is quantified through Environmental Quality Index (EQI) which consists of three indicators, i.e. river quality index, air quality index, and coverage of land cover. The current of this instrument data processing was done by averaging and weighting each index to represent the EQI at the provincial level. However, we found EQI interpretations that may contain some uncertainties and have a range of circumstances possibly less appropriate if processed under a common statistical approach. In this research, we aim to manage the indicators of EQI with a more intuitive computation technique and make some inferences related to the environmental performance in 33 provinces in Indonesia. Research was conducted in three stages of Mamdani Fuzzy Inference System (MAFIS), i.e. fuzzification, data inference, and defuzzification. Data input consists of 10 environmental parameters and the output is an index of Environmental Quality Performance (EQP). Research was applied to the environmental condition data set in 2015 and quantified the results into the scale of 0 to 100, i.e. 10 provinces at good performance with the EQP above 80 dominated by provinces in eastern part of Indonesia, 22 provinces with the EQP between 80 to 50, and one province in Java Island with the EQP below 20. This research shows that environmental quality performance can be quantified without eliminating the natures of the data set and simultaneously is able to show the environment behavior along with its spatial pattern distribution.

    The shortage of nurses in operating room departments (ORs) in Sweden and other countries can lead to reduced capacity and quality in healthcare, as well as more intense work for those on the job. Little is known about what nurses in ORs perceive as crucial for their workplace to be attractive. To capture attractive qualities of nurses' work in Swedish ORs and take a first step in the process of adapting the Attractive Work Questionnaire for use in a health care context. The Attractive Work Questionnaire was completed by 147 (67% ) nurses in four Swedish ORs. Principal Component Analyses (PCA) were performed to determine the underlying structure of the data. Factors contributing to job attractiveness identified in the area "work conditions" were: relations, leadership, equipment, salary, organisation, physical work environment, location, and working hours; in the area "work content": mental work, autonomy and work rate; and in the area "job satisfaction": status and acknowledgement. The PCA showed consistency with the original Attractive Work Questionnaire, Cronbach's alpha varied between 0.57-0.90. Prominent attractive qualities for nurses' work in Swedish ORs were possible to identify through the Attractive Work Questionnaire and the results suggest that the questionnaire can be useful in a health care context.

    Communication between professionals is essential because it contributes to an optimal continuum of care. Whether patients experience adequate continuum of care is uncertain. To address this, a questionnaire was developed to elucidate this care process from a patients' perspective. In this study, the instrument's ability to measure differences in "Consumer Quality Index Continuum of Care" scores between hospitals was investigated. The questionnaire was mailed to a random sample of 2159 patients and comprised of 22 items divided over four domains, GP approach, GP referral, specialist and collaboration. Multilevel analysis was conducted to identify case-mix and determine this questionnaire's ability to measure differences in domain scores between hospitals. Based on a 65% response rate, 1404 questionnaires were available for analysis. Case-mix of patient characteristics across hospitals could not be demonstrated. Some differences in scores between hospitals were observed. At most two in eight hospitals showed different domain scores. The ability of this questionnaire to measure differences in continuum of care scores between hospitals is limited. The outcome of this survey suggests that hospitals provide a similar level of continuum of care from a patient's perspective. This questionnaire is especially useful for measuring differences between patients. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Many measurements have been developed to assess the quality of death (QoD). Among these, the Quality of Dying and Death Questionnaire (QODD) is the most widely studied and best validated. Informal carers and health professionals who care for the patient during their last days of life can complete this assessment tool. The aim of the study is to carry out a cross-cultural adaptation and a psychometric analysis of the QODD for the Spanish population. The translation was performed using a double forward and backward method. An expert panel evaluated the content validity. The questionnaire was tested in a sample of 72 Spanish-speaking adult carers of deceased cancer patients. A psychometric analysis was performed to evaluate internal consistency, divergent criterion-related validity with the Mini-Suffering State Examination (MSSE) and concurrent criterion-related validity with the Palliative Outcome Scale (POS). Some items were deleted and modified to create the Spanish version of the QODD (QODD-ESP-26). The instrument was readable and acceptable. The content validity index was 0.96, suggesting that all items are relevant for the measure of the QoD. This questionnaire showed high internal consistency (Cronbach's α coefficient = 0.88). Divergent validity with MSSE (r = -0.64) and convergent validity with POS (r = -0.61) were also demonstrated. The QODD-ESP-26 is a valid and reliable instrument for the assessment of the QoD of deceased cancer patients that can be used in a clinical and research setting. Copyright © 2018 Elsevier Ltd.

    The accurate quantification of sensory difference/similarity between foods, as well as consumer acceptance/preference and concepts, is greatly needed to optimize and maintain food quality. The R-Index is one class of measures of the degree of difference/similarity, and was originally developed for sensory difference tests for food quality control, product development, and so on. The index is based on signal detection theory and is free of the response bias that can invalidate difference testing protocols, including categorization and same-different and A-Not A tests. It is also a nonparametric analysis, making no assumptions about sensory distributions, and is simple to compute and understand. The R-Index is also flexible in its application. Methods based on R-Index analysis have been used as detection and sensory difference tests, as simple alternatives to hedonic scaling, and for the measurement of consumer concepts. This review indicates the various computational strategies for the R-Index and its practical applications to consumer and sensory measurements in food science.

    Sleep disorders among shift workers are common problems due to the disturbed circadian rhythm. The Bergen Shift Work Sleep Questionnaire assesses discrete sleep problems related to work shifts (day, evening and night shifts) and rest days. The aim of the study was to develop the Hungarian version of this questionnaire and to compare the sleep quality of nurses in different work schedules. 326 nurses working in shifts filled in the questionnaire. The authors made convergent and discriminant validation of the questionnaire with the Athens Insomnia Scale and the Perceived Stress Questionnaire. The questionnaire based on psychometric characteristics was suitable to assess sleep disorders associated with shift work in a Hungarian sample. The frequency of discrete symptoms significantly (p<0.001) differed with the shifts. Nurses experienced the worst sleep quality and daytime fatigue after the night shift. Nurses working in irregular shift system had worse sleep quality than nurses working in regular and flexible shift system (p<0.001). The sleep disorder of nurses working in shifts should be assessed with the Hungarian version of the Bergen Shift Work Sleep Questionnaire on a nationally representative sample, and the least burdensome shift system could be established.

  11. Deriving health utilities from the MacNew Heart Disease Quality of Life Questionnaire.

    Quality of life is included in the economic evaluation of health services by measuring the preference for health states, i.e. health state utilities. However, most intervention studies include a disease-specific, not a utility, instrument. Consequently, there has been increasing use of statistical mapping algorithms which permit utilities to be estimated from a disease-specific instrument. The present paper provides such algorithms between the MacNew Heart Disease Quality of Life Questionnaire (MacNew) instrument and six multi-attribute utility (MAU) instruments, the Euroqol (EQ-5D), the Short Form 6D (SF-6D), the Health Utilities Index (HUI) 3, the Quality of Wellbeing (QWB), the 15D (15 Dimension) and the Assessment of Quality of Life (AQoL-8D). Heart disease patients and members of the healthy public were recruited from six countries. Non-parametric rank tests were used to compare subgroup utilities and MacNew scores. Mapping algorithms were estimated using three separate statistical techniques. Mapping algorithms achieved a high degree of precision. Based on the mean absolute error and the intra class correlation the preferred mapping is MacNew into SF-6D or 15D. Using the R squared statistic the preferred mapping is MacNew into AQoL-8D. The algorithms reported in this paper enable MacNew data to be mapped into utilities predicted from any of six instruments. This permits studies which have included the MacNew to be used in cost utility analyses which, in turn, allows the comparison of services with interventions across the health system. © The European Society of Cardiology 2014.

    2013-01-01

    Background Using treated wastewater in agriculture irrigation could be a realistic solution for the shortage of fresh water in Iran, however, it is associated with environmental and health threats; therefore, effluent quality assessment is quite necessary before use. The present study aimed to evaluate the physicochemical and microbial quality of Shiraz wastewater treatment plant effluent for being used in agricultural irrigation. In this study, 20 physicochemical and 3 microbial parameters were measured during warm (April to September) and cold months (October to march). Using the measured parameters and the Canadian Water Quality Index, the quality of the effluent was determined in both warm and cold seasons and in all the seasons together. Results The calculated index for the physicochemical parameters in the effluent was equal (87) in warm and cold months and it was obtained as 85 for the seasons all together. When the microbial parameters were used in order to calculate the index, it declined to 67 in warm and cold seasons and 64 in all the seasons together. Also, it was found that three physicochemical parameters (TDS, EC, and NO3) and three microbial parameters (Fecal coliform, Helminthes egg, and Total coliform) had the most contribution to the reduction of the index value. Conclusions The results showed that the physicochemical quality of Shiraz Wastewater Treatment Plant Effluent was good for irrigation in the warm, cold, and total of the two kinds of seasons. However, by applying the microbial parameter, the index value declined dramatically and the quality of the effluent was marginal. PMID:23566673

    Questionnaires can be used to assess perceived indoor air quality and symptoms in schools. Questionnaires for primary school aged children have traditionally been parent-administered, but self-administered questionnaires would be easier to administer and may yield as good, if not better, information. Our aim was to compare the repeatability of self- and parent-administered indoor air questionnaires designed for primary school aged pupils. Indoor air questionnaire with questions on child's symptoms and perceived indoor air quality in schools was sent to parents of pupils aged 7-12 years in two schools and again after two weeks. Slightly modified version of the questionnaire was administered to pupils aged 9-12 years in another two schools and repeated after a week. 351 (52%) parents and 319 pupils (86%) answered both the first and the second questionnaire. Test-retest repeatability was assessed with intra-class correlation (ICC) and Cohen's kappa coefficients (k). Test-retest repeatability was generally between 0.4-0.7 (ICC; k) in both self- and parent-administered questionnaire. In majority of the questions on symptoms and perceived indoor air quality test-retest repeatability was at the same level or slightly better in self-administered compared to parent-administered questionnaire. Agreement of self- and parent administered questionnaires was generally < 0.4 (ICC; k) in reported symptoms and 0.4-0.6 (ICC; k) in perceived indoor air quality. Children aged 9-12 years can give as, or even more, repeatable information about their respiratory symptoms and perceived indoor air quality than their parents. Therefore, it may be possible to use self-administered questionnaires in future studies also with children.

    While there are questionnaires for evaluating the effects of skin cancer on patient quality of life, there are no specific questionnaires available in Spanish for evaluating quality of life in patients with actinic keratosis. The aim of this study was to translate and culturally adapt the Actinic Keratosis Quality of Life (AKQoL) questionnaire into Spanish. The original questionnaire was translated into Spanish following the guidelines for the cross-cultural adaptation of self-report measures. Several measures of general reliability and validity were calculated, including Cronbach α for internal consistency and the Spearman rank-order correlation coefficient and a Bland-Altman plot for test-retest reliability. To test concurrent validity, we used the Pearson correlation coefficient to measure the correlation between AKQoL and Skindex-29 scores. The final version of the questionnaire was administered to 621 patients with actinic keratosis, who scored a mean (SD) of 5.25 (4.73) points (total possible score, 0-25). The Cronbach α reliability coefficient analysis was 0.84. The correlation between the mean (SD) score on the Skindex-29 (1.87 [4.07]) and on the AKQoL (1.97 [2.98] was 0.344 (P=.002, Spearman's rho), with a proportion of shared variance of 11.8%. The translation, cross-cultural adaptation, and validation of the original AKQoL produced a reliable, easily understandable questionnaire for evaluating the impact of actinic keratosis on the quality of life of patients in our setting.

    We aimed to compare data quality from online and postal questionnaires and to evaluate the practicality of these different questionnaire modes in a cancer sample. Participants in a study investigating the psychosocial sequelae of testicular cancer could choose to complete a postal or online version of the study questionnaire. Data quality was evaluated by assessing sources of nonobservational errors such as participant nonresponse, item nonresponse and sampling bias. Time taken and number of reminders required for questionnaire return were used as indicators of practicality. Participant nonresponse was significantly higher among participants who chose the postal questionnaire. The proportion of questionnaires with missing items and the mean number of missing items did not differ significantly by mode. A significantly larger proportion of tertiary-educated participants and managers/professionals completed the online questionnaire. There were no significant differences in age, relationship status, employment status, country of birth or language spoken by completion mode. Compared with postal questionnaires, online questionnaires were returned significantly more quickly and required significantly fewer reminders. These results demonstrate that online questionnaire completion can be offered in a cancer sample without compromising data quality. In fact, data quality from online questionnaires may be superior due to lower rates of participant nonresponse. Investigators should be aware of potential sampling bias created by more highly educated participants and managers/professionals choosing to complete online questionnaires. Besides this issue, online questionnaires offer an efficient method for collecting high-quality data, with faster return and fewer reminders. Copyright © 2011 John Wiley & Sons, Ltd.

    ABSTRACT Background : The satisfactory outcome in the surgical treatment of obesity must include, in addition to weight loss, a significant change in the pre-existing comorbidities and in the quality of life of the patients. Aim : To evaluate the quality of life in the late postoperative period in patients that underwent videolaparoscopic sleeve gastrectomy. Methods : Was applied the questionnaire “Bariatric Analysis and Reporting Outcome System” (BAROS) in patients that underwent videolaparoscopic sleeve gastrectomy. Results : A total of 47 patients between 21-60 years old were evaluated. The total mean of the BMI before surgery was 43.06±5.87 kg/m². The average percentage of the reduction of excess weight after surgery was 85.46±23.6%. The score obtained by patients in the questionnaire about the improvement in the quality of life showed excellent (36.17%), very good (40.43%), good (21.28%) and reasonable (2.13%) results. There was clinical improvement after surgery in all comorbidities investigated. Conclusion : BAROS showed excellent results in 36.17%, very good in 40.43%, good in 21.28% and reasonable in 2.13%. The weight loss was critical to improve the quality of life and offered the resolution or clinical improvement in all of the investigated comorbidities. PMID:29340547

    The present hydrogeochemical study was confined to the Thoothukudi District in Tamilnadu, India. A total of 100 representative water samples were collected during pre-monsoon and post-monsoon and analyzed for the major cations (sodium, calcium, magnesium and potassium) and anions (chloride, sulfate, bicarbonate, fluoride and nitrate) along with various physical and chemical parameters (pH, total dissolved salts and electrical conductivity). Water quality index rating was calculated to quantify the overall water quality for human consumption. The PRM samples exhibit poor quality in greater percentage when compared with POM due to dilution of ions and agricultural impact. The overlay of WQI with chloride and EC corresponds to the same locations indicating the poor quality of groundwater in the study area. Sodium (Na %), sodium absorption ratio (SAR), residual sodium carbonate (RSC), residual sodium bicarbonate, permeability index (PI), magnesium hazards (MH), Kelly's ratio (KR), potential salinity (PS) and Puri's salt index (PSI) and domestic quality parameters such as total hardness (TH), temporary, permanent hardness and corrosivity ratio (CR) were calculated. The majority of the samples were not suitable for drinking, irrigation and domestic purposes in the study area. In this study, the analysis of salinization/freshening processes was carried out through binary diagrams such as of mole ratios of {SO}_{ 4}^{ 2- } /Cl- and Cl-/EC that clearly classify the sources of seawater intrusion and saltpan contamination. Spatial diagram BEX was used to find whether the aquifer was in the salinization region or in the freshening encroachment region.

    Background Systemic lupus erythematosus (SLE) may have a profound impact on quality of life. There is increasing interest in measuring quality of life in lupus patients. The purpose of this study was to investigate the validity and reliability of SLE Quality of Life Questionnaire (L-QoL) in Turkish SLE patients. Methods SLE according to 2012 Systemic Lupus International Collaborating Clinics Classification Criteria were recruited into the study. Demographic data, clinical parameters and disease activity measured with the Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K); were noted. Nottingham Health Profile and Health Assessment Questionnaire were filled out in addition to the Turkish L-QoL (LQoL-TR). Internal consistency, test-retest reliability, and convergent and discriminant validity were evaluated. Results The mean age of participants was 43.55 ± 14.33 years and the mean disease duration was 89.8 ± 92.1 months. The patients filled out LQoL-TR in 2.5 min. Strong correlation of LQoL-TR with all subgroups of the Nottingham Health Profile and the Health Assessment Questionnaire were established showing the convergent validity. The highest correlation was demonstrated with emotional reactions (rho = 0.72) and sleep component (rho = 0.65) of the Nottingham Health Profile scale ( p < 0.0001). Its poor and not significant correlation with nonfunctional parameters (age, disease duration, perceived general health, SLEDAI-2K) showed its discriminative properties. LQoL-TR demonstrated good internal reliability with a Cronbach's α of 0.93 and test-retest reliability with intraclass correlation coefficient of 0.87. Conclusion The LQoL-TR is a practical and useful tool which demonstrates good validity and reliability.

    The Quality of Life in Hand Eczema Questionnaire (QOLHEQ) is the only instrument assessing disease-specific health-related quality of life in patients with hand eczema. It is available in eight language versions. In this study we assessed if the items of different language versions of the QOLHEQ yield comparable values across countries. An international multicenter study was conducted with participating centers in Finland, Germany, Japan, The Netherlands, Sweden, and Turkey. Methods of item response theory were applied to each subscale to assess differential item functioning for items among countries. Overall, 662 hand eczema patients were recruited into the study. Single items were removed or split according to the item response theory model by country to resolve differential item functioning. After this adjustment, none of the four subscales of the QOLHEQ showed significant misfit to the item response theory model (P < 0.01), and a Person Separation Index of greater than 0.7 showed good internal consistency for each subscale. By adapting the scoring of the QOLHEQ using the methods of item response theory, it was possible to obtain QOLHEQ values that are comparable across countries. Cross-cultural variations in the interpretation of single items were resolved. The QOLHEQ is now ready to be used in international studies assessing the health-related quality of life impact of hand eczema. Copyright © 2017 The Authors. Published by Elsevier Inc.

    A cross-sectional, validation study. To (a) develop the Spanish version of the Quality of Life Index-Spinal Cord Injury version (SV-QLI/SCI) and (b) assess its psychometric characteristics among permanent wheelchair users and specifically among those with SCI. Associations of wheelchair users in Mallorca (Spain). Two forward and backward translations of the QLI/SCI into Spanish were carried out separately. Seventy-seven subjects were randomly selected among the members of the associations. They completed the SV-QLI/SCI and validated instruments to measure depression and spinal pain upon recruitment and 14 days later. Assessments included comprehensibility, reproducibility, floor and ceiling effects and correlations between quality of life, pain and depression (Spearman's correlation coefficient). Analyses were repeated excluding data from subjects without SCI. Three items of the SV-QLI/SCI required rephrasing. Reproducibility was 'almost perfect' for the entire questionnaire and its 'Health and functioning' subscale, 'substantial' for the 'Social and economic' and 'Family' subscales and 'moderate' for the 'Psychological/spiritual' subscale. Floor effect was not observed, and only for the 'Family' subscale >3% of the subjects reached the maximum possible score. The correlation between quality of life and depression was the strongest (r=-0.628). Results were virtually identical in the subsample with SCI. These results support the use of the SV-QLI/SCI among Spanish-speaking wheelchair users.

    To assess the association between dietary glycemic index (GI), glycemic load (GL) and dietary quality indices in Iranian adults. This cross section was conducted among 1571 Iranian adults aged  ≥19 years. GI, GL and diet quality indices were estimated by 24-h recall and DDS was calculated using a validated 48-item food frequency questionnaire. Participants who were in the top tertile of GI had lower healthy eating index (HEI) (57.2 ± 7.8 versus 55.6 ± 8.7; p < 0.001), dietary diversity score (DDS) (3.6 ± 0.9 versus 3.3 ± 1.1; p < 0.001) and nutrient adequacy ratios (NARs) for Zn, Ca, vitamin C and B2. Individuals in the lowest tertile of GL had lower HEI, MAR and NARs for Zn, vitamin B2, B3, B6, B12, vitamin D. Both GI and GL were positively related to dietary diversity score (DED) (p < 0.001). The inverse associations for GI and GL with diet quality indices may suggest the relevance of carbohydrate source in determining the diet quality indices.

    The influence of ultrasound in combination with elevated temperature (thermosonication) is important in inactivation effects on microorganisms. However, overall quality of these products can be deteriorated. The aim of this study was to examine the use of a single quality index in evaluating effects of ultrasound technology on quality characteristics of blueberry and cranberry juices and nectars. For the purpose of this study based on 10 quality parameters, two mathematical models for calculating a single total quality index have been introduced. Samples were treated according to the experimental design, with high power ultrasound frequency of 20 kHz under various conditions (treatment time: 3, 6 and 9 min, sample temperature: 20 ℃, for thermosonication: 40 and 60 ℃ and amplitude: 60, 90 and 120 µm). Mathematical index of total quality index in order to evaluate total quality of ultrasound-treated juices and nectars was established. For cranberry juices, treatments '11' (amplitude 120 µm) and '16' (amplitude 60 µm) both for 9 min and the temperature of 20 ℃ were best scored for both models. Treatment '6' (amplitude 120 µm, 3 min treatment time and the sample temperature of 20 ℃) for cranberry nectars was among the best for both models. Ultrasound treatments '6' of amplitude 120 µm, 3 min and the temperature of 20 ℃ and '11' same amplitude 120 µm and temperature, but 9 min were best scored blueberry juices for both models. Blueberry nectar had best total quality index for treatments '5' (amplitude 120 µm, 6 min treatment time and the sample temperature of 40 ℃) and '6' (amplitude 120 µm, 3 min treatment time and the sample temperature of 20 ℃).

    In this study, we aimed to develop and validate an instrument that could be used by patients with cancer to evaluate their quality of palliative care. Development of the questionnaire followed the four-phase process: item generation and reduction, construction, pilot testing, and field testing. Based on the literature, we constructed a list of items for the quality of palliative care from 104 quality care issues divided into 14 subscales. We constructed scales of 43 items that only the cancer patients were asked to answer. Using relevance and feasibility criteria and pilot testing, we developed a 44-item questionnaire. To assess the sensitivity and validity of the questionnaire, we recruited 220 patients over 18 years of age from three Korean hospitals. Factor analysis of the data and fit statistics process resulted in the 4-factor, 32-item Quality Care Questionnaire-Palliative Care (QCQ-PC), which covers appropriate communication with health care professionals (ten items), discussing value of life and goals of care (nine items), support and counseling for needs of holistic care (seven items), and accessibility and sustainability of care (six items). All subscales and total scores showed a high internal consistency (Cronbach alpha range, 0.89 to 0.97). Multi-trait scaling analysis showed good convergent (0.568-0.995) and discriminant (0.472-0.869) validity. The correlation between the total and subscale scores of QCQ-PC and those of EORTC QLQ-C15-PAL, MQOL, SAT-SF, and DCS was obtained. This study demonstrates that the QCQ-PC can be adopted to assess the quality of care in patients with cancer.

    Our goal was to validate an instrument with which terminally ill patients could evaluate the quality of care they receive at the end of life (EOL). Questionnaire development followed a four-phase process: item generation and reduction, construction, pilot testing, and field-testing. Using relevance and priority criteria and pilot testing, we developed a 16-item questionnaire. Factor analyses of data from 235 patients resulted in the Quality Care Questionnaire-End of Life (QCQ-EOL) covering dignity-conserving care, care by health care professionals, individualised care, and family relationships. All subscales and total scores showed high internal consistency (Cronbach alpha range, 0.73-0.89). The ability of total score and selective subscale scores clearly differentiated patients on the basis of clinical situation, sense of dignity, and general rating of care quality. Correlations of scores between patients and caregivers were substantial. The QCQ-EOL can be adopted to assess the quality of care received by terminally ill patients.

    Childhood illness or disability can affect the quality of life (QoL) of the child's primary caregiver. Our aim was to identify, describe the content and systematically review the psychometric properties of condition-specific QoL questionnaires for caregivers of children. Medline, PsycInfo, Embase, CINAHL, and the Cochrane library databases were searched from 1 January 1990 to 30 June 2011. Articles related to the development and measurement of caregiver QoL were screened to identify condition-specific questionnaires. The characteristics of the questionnaires were extracted, and their psychometric properties were evaluated using the consensus-based standards for the selection of health measurement instruments checklist with 4-point scale. We identified 25 condition-specific caregiver QoL questionnaires covering 16 conditions. Conditions included atopic dermatitis, asthma, diabetes, oro-facial disorders, and two acute illnesses. Questionnaires were developed predominantly in high-income countries. Questionnaires had the highest quality rating for content validity, followed by hypothesis testing. Methodological quality was satisfactory for criterion validity; fair in reliability and responsiveness; and poor in internal consistency and structural validity. The increasing number of questionnaires developed over time shows improved recognition of the importance of caregiver QoL. There is a paucity of QoL questionnaires for caregivers of otherwise healthy children suffering from physical injuries and acute conditions associated with significant caregiver burden. Cultural validation of existing and new questionnaires in lower-income countries is necessary. Data collected by condition-specific questionnaires can assist clinicians and health economists in estimating caregiver burden and the types of healthcare services caregivers require and may be useful for healthcare administrators to evaluate interventions.

    Evaluation of patients' health care experiences is central to measuring patient-centred care. However, different instruments tend to be used at the hospital or departmental level but rarely both, leading to a lack of standardization of patient experience measures. To validate the Consumer Quality Index (CQI) Inpatient Hospital Care for use on both department and hospital levels. Using cross-sectional observational data, we investigated the internal validity of the questionnaire using confirmatory factor analyses (CFA), and the generalizability of the questionnaire for use at the department and hospital levels using generalizability theory. 22924 adults hospitalized for ≥24 hours between 1 January 2013 and 31 December 2014 in 23 Dutch hospitals (515 department evaluations). CQI Inpatient Hospital Care questionnaire. CFA results showed a good fit on individual level (CFI=0.96, TLI=0.95, RMSEA=0.04), which was comparable between specialties. When scores were aggregated to the department level, the fit was less desirable (CFI=0.83, TLI=0.81, RMSEA=0.06), and there was a significant overlap between communication with doctors and explanation of treatment subscales. Departments and hospitals explained ≤5% of total variance in subscale scores. In total, 4-8 departments and 50 respondents per department are needed to reliably evaluate subscales rated on a 4-point scale, and 10 departments with 100-150 respondents per department for binary subscales. The CQI Inpatient Hospital Care is a valid and reliable questionnaire to evaluate inpatient experiences in Dutch hospitals provided sufficient sampling is done. Results can facilitate meaningful comparisons and guide quality improvement activities in individual departments and hospitals. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    In recent years, the problem of air pollution becomes more and more serious. Based on the geographic and seasonal climatic characteristics of Xuchang City, this paper studies the temporal and spatial distribution characteristics of air quality index. The results show that: from the time point of view, air quality index shows seasonal difference. Air quality index is highest in winter and is lowest in summer. From the space point of view, there are differences between the north and the south to a certain extent. Changge City, Yuzhou city and central Xuchang county is higher than the southeast of Xiangcheng county and Yanling county. The spatial and temporal variation characteristics of air quality index in Xuchang are influenced by natural factors and human activities, and the economic development and population are the important factors affecting the urban air quality.

    Electronic patient-reported outcomes (PRO) provide quick and usually reliable assessments of patients' health-related quality of life (HRQL). An electronic version of the Patient-Reported Outcomes Quality of Life-human immunodeficiency virus (PROQOL-HIV) questionnaire was developed, and its face validity and reliability were assessed using standard psychometric methods. A sample of 80 French outpatients (66% male, 52/79; mean age 46.7 years, SD 10.9) were recruited. Paper-based and electronic questionnaires were completed in a randomized crossover design (2-7 day interval). Biomedical data were collected. Questionnaire version and order effects were tested on full-scale scores in a 2-way ANOVA with patients as random effects. Test-retest reliability was evaluated using Pearson and intraclass correlation coefficients (ICC, with 95% confidence interval) for each dimension. Usability testing was carried out from patients' survey reports, specifically, general satisfaction, ease of completion, quality and clarity of user interface, and motivation to participate in follow-up PROQOL-HIV electronic assessments. Questionnaire version and administration order effects (N=59 complete cases) were not significant at the 5% level, and no interaction was found between these 2 factors (P=.94). Reliability indexes were acceptable, with Pearson correlations greater than .7 and ICCs ranging from .708 to .939; scores were not statistically different between the two versions. A total of 63 (79%) complete patients' survey reports were available, and 55% of patients (30/55) reported being satisfied and interested in electronic assessment of their HRQL in clinical follow-up. Individual ratings of PROQOL-HIV user interface (85%-100% of positive responses) confirmed user interface clarity and usability.

    This study aims to adapt and validate the Spanish version of the Osteoarthritis Knee and Hip Quality of Life (OAKHQOL) questionnaire. The OAKHQOL was adapted into Spanish using a forward-backward translation methodology. The Spanish version was then validated in a prospective, mixed-design study of 759 patients with hip or knee osteoarthritis (OA). Patients completed the OAKHQOL, Short Form 36 (SF-36), Western Ontario and McMaster Universities Osteoarthritis Index, and the EQ-5D. The internal consistency was evaluated using Cronbach's alpha. Convergent validity was assessed by examining correlations between the OAKHQOL and other patient-reported instruments; known groups' validity was assessed by determining the capacity of the OAKHQOL to discriminate between patients with different levels of disease severity measured using the Lequesne Index. Test-retest reliability was evaluated by calculating the intraclass correlation coefficient (ICC) for all OAKHQOL domains in 409 stable patients with OA. Responsiveness was evaluated by calculating effect sizes among 129 patients undergoing hip or knee replacement. Cronbach's alpha for the five domains of the OAKHQOL ranged from 0.60 to 0.93 while ICCs ranged from 0.75 to 0.81 for all domains except the two social domains. Statistically significant differences (p < 0.001) were observed between patients with different degrees of disease severity on all domains except "social support". The instrument showed convergent validity among hypothesized domains (p < 0.001). Results of the study supported that the Spanish version OAKHQOL questionnaire was a valid instrument to measure health-related quality of life in patients with OA of the lower limb.

    The Stark questionnaire measures health-related quality of life (QoL) using pictures almost exclusively. It is supplemented by a minimum of words. It comprises a mental and a physical health component. A German sample of n = 500 subjects, age and gender stratified, filled out the Stark Qol questionnaire along with various other questionnaires via internet. The physical component shows good reliability (Cronbach's alpha = McDonalds Omega = greatest lower bound = .93), the mental component can be improved (Cronbach's alpha = .63, McDonalds Omega = .72, greatest lower bound = .77). Confirmatory factor analysis shows a good fit (Bentlers CFI = .97). Construct validity was proven. The Stark QoL is a promising new development in measuring QoL, it is a short and easy to apply questionnaire. Additionally, it is particularly promising for international research.

    The relative weighting on traits within breeding goals are generally determined by bio-economic models or profit functions. While such methods have generally delivered profitability gains to producers, and are being expanded to consider non-market values, current approaches generally do not consider the numerous and diverse stakeholders that affect, or are affected, by such tools. Based on principles of respondent anonymity, iteration, controlled feedback and statistical aggregation of feedback, a Delphi study was undertaken to gauge stakeholder opinion of the importance of detailed milk quality traits within an overall dairy breeding goal for profit, with the aim of assessing its suitability as a complementary, participatory approach to defining breeding goals. The questionnaires used over two survey rounds asked stakeholders: (a) their opinion on incorporating an explicit sub-index for milk quality into a national breeding goal; (b) the importance they would assign to a pre-determined list of milk quality traits and (c) the (relative) weighting they would give such a milk quality sub-index. Results from the survey highlighted a good degree of consensus among stakeholders on the issues raised. Similarly, revelation of the underlying assumptions and knowledge used by stakeholders to make their judgements illustrated their ability to consider a range of perspectives when evaluating traits, and to reconsider their answers based on the responses and rationales given by others, which demonstrated social learning. Finally, while the relative importance assigned by stakeholders in the Delphi survey (4% to 10%) and the results of calculations based on selection index theory of the relative emphasis that should be placed on milk quality to halt any deterioration (16%) are broadly in line, the difference indicates the benefit of considering more than one approach to determining breeding goals. This study thus illustrates the role of the Delphi technique, as a complementary

    Chronic obstructive pulmonary disease reduces functional capacity, which is strongly correlated with the morbidity and mortality of patients. The BODE index considers the multifactorial nature of the disease, including the functional capacity measured by the 6-min walk test (6MWT), and this index predicts the mortality in patients with chronic obstructive pulmonary disease. Our aim was to assess whether association exists between the original BODE index and the modified BODE index by replacing the 6MWT with the scores from the Pulmonary Functional Status and Dyspnea Questionnaire-Modified version (PFSDQ-M), Human Activity Profile (HAP) questionnaire, and the results of the Glittre ADL Test (TGlittre). Twenty-eight subjects diagnosed with chronic obstructive pulmonary disease underwent the 6MWT and TGlittre and responded to the PFSDQ-M and HAP questionnaires. Four BODE index scores were obtained: 1 calculated by using the original method (ie, using the 6MWT) and 3 others calculated by using the results obtained from the TGlittre, PFSDQ-M, and HAP (the modified BODE index scores). High levels of association were observed between the original BODE index and the BODE TGlittre (R = 0.824, P ≤ .0001), BODE PFSDQ-M (R = 0.803, P ≤ .0001), and BODE HAP (R = 0.500, P ≤ .0001). The BODE TGlittre, and BODE PFSDQ-M may be used as alternatives to the 6MWT when physical space is not available to perform the 6MWT or when the condition of a patient does not allow performance of the 6MWT.

    Background: Since there is no disease-specific instrument for measuring quality-of-life (QOL) in Ostomy patients in Persian language. Aim: This study was designed to translate and evaluate the validity and reliability of City of Hope-quality of life-Ostomy questionnaire (COH-QOL-Ostomy questionnaire). Subjects and Methods: This study was designed as cross-sectional study. Reliability of the subscales and the summary scores were demonstrated by intra-class correlation coefficients. Pearson's correlations of an item with its own scale and other scales were calculated to evaluated convergent and discriminant validity. Clinical validity was also evaluated by known-group comparisons. Results: Cronbach's alpha coefficient for all subscales was about 0.70 or higher. Results of interscale correlation were satisfactory and each subscale only measured a single and specified trait. All subscales met the standards of convergent and discriminant validity. Known group comparison analysis showed significant differences in social and spiritual well-being. Conclusion: The findings confirmed the reliability and validity of Persian version of COH-QOL-Ostomy questionnaire. The instrument was also well received by the Iranian patients. It can be considered as a valuable instrument to assess the different aspects of health related quality-of-life in Ostomy patients and used in clinical research in the future. PMID:25221719

    This study was carried out to evaluate the psychometric properties of an Iranian translation of the Work Ability Index (WAI) questionnaire. In this methodological study, nurses and healthcare workers aged 40 years and older who worked in educational hospitals in Ahvaz (236 workers) in 2010, completed the questionnaire and 60 of the workers filled out the WAI questionnaire for the second time to ensure test-retest reliability. Forward-backward method was applied to translate the questionnaire from English into Persian. The psychometric properties of the Iranian translation of the WAI were assessed using the fallowing tests: Internal consistency (to test reliability), test-retest analysis, exploratory factor analysis (construct validity), discriminate validity by comparing the mean WAI score in two groups of the employees that had different levels of sick leave, criterion validity by determining the correlation between the Persian version of short form health survey (SF-36) and WAI score. Cronbach's alpha coefficient was estimated to be 0.79 and it was concluded that the internal consistency was high enough. The intraclass correlation coefficient was recognized to be 0.92. Factor analysis indicated three factors in the structure of the work ability including self-perceived work ability (24.5% of the variance), mental resources (22.23% of the variance), and presence of disease and health related limitation (18.55% of the variance). Statistical tests showed that this questionnaire was capable of discriminating two groups of employees who had different levels of sick leave. Criterion validity analysis showed that this instrument and all dimensions of the Iranian version of SF-36 were correlated significantly. Item correlation corrective for overlap showed the items tests had a good correlation except for one. The finding of the study showed that the Iranian version of the WAI is a reliable and valid measure of work ability and can be used both in research and practical

    Questionnaires measuring health-related quality of life are difficult to perform and obtain for patients and professionals. Computerised tools are now available to collect this information. The objective of this study was to assess the ability of patients undergoing total knee replacement to fill in health-related quality-of-life questionnaires using a telematic platform. Ninety eight consecutive patients undergoing total knee arthroplasty were included. Participants were given an access code to enter the website where they had to respond to 2 questionnaires (SF8 and the reduced WOMAC), and 3 additional questions about the difficulty in completing the questionnaires. A total of 98 patients agreed to participate: 45 males and 53 females (mean age 72.7 years). Fourteen did not agree to participate due to lack of internet access. Of the final 84 participants, 50% entered the website, and only 36 answered all questions correctly. Of the patients who answered the questionnaire, 80% were helped by a relative or friend, and 22% reported difficulty accessing internet. The use of telematic systems to respond to health-related quality of life questionnaires should be used cautiously, especially in elderly population. It is likely that the population they are directed at is not prepared to use this type of technology. Therefore, before designing telematics questionnaires it must be ensured that they are completed properly. Copyright © 2014 SECOT. Published by Elsevier Espana. All rights reserved.

    Audiometric tests provide information about hearing in otitis media with effusion (OME). Questionnaires can supplement this information by supporting clinical history-taking as well as potentially providing a standardized and comprehensive assessment of the impact of the disease on a child. There are many possible candidate questionnaires. This study aimed to assess the quality and usability of parent / child questionnaires in OME assessment. Fifteen, published questionnaires, commonly used in audiological departments (Auditory Behaviour in Everyday Life (ABEL), Children's Auditory Performance Scale (CHAPS), Children's Home Inventory for Listening Difficulties (CHILD), Children's Outcome Worksheets (COW), Evaluation of Children's Listening and Processing Skills (ECLiPS), Early Listening Function (ELF), Fisher's Auditory Problem Checklist (FAPC), Hearing Loss 7 (HL-7), Listening Inventory for Education- Revised (LIFE-R Student), Listening Inventory for Education UK Individual Hearing Profile (LIFE-UK IHP), LittlEARS Auditory Questionnaire (LittlEARS), Listening Situations Questionnaire (LSQ), Otitis Media 6 (OM-6), Quality of Life in Children's Ear Problems (OMQ-14), Parents' Evaluation of Aural/Oral Performance of Children (PEACH) were assessed according to the following 8 criteria: conceptual clarity, respondent burden, reliability, validity, normative data, item bias, ceiling/ floor effects, and administrative burden. ECLiPS, LittlEARS and PEACH scored highest overall based on the assessment criteria established for this study. None of the questionnaires fully satisfied all 8 criteria. Although all questionnaires assessed issues considered to be of at least adequate relevance to OME, the majority had weaknesses with respect to the assessment of psychometric properties, such as item bias, floor/ceiling effects or measurement reliability and validity.

    To critically appraise and compare the measurement properties of the original versions of neck-specific questionnaires. Bibliographic databases were searched for articles concerning the development or evaluation of the measurement properties of an original version of a self-reported questionnaire, evaluating pain and/or disability, which was specifically developed or adapted for patients with neck pain. The methodological quality of the selected studies and the results of the measurement properties were critically appraised and rated using a checklist, specifically designed for evaluating studies on measurement properties. The search strategy resulted in a total of 3,641 unique hits, of which 25 articles, evaluating 8 different questionnaires, were included in our study. The Neck Disability Index is the most frequently evaluated questionnaire and shows positive results for internal consistency, content validity, structural validity, hypothesis testing, and responsiveness, but a negative result for reliability. The other questionnaires show positive results, but the evidence for each measurement property is mostly limited, and at least 50% of the information on measurement properties per questionnaire is lacking. Our findings imply that studies of high methodological quality are needed to properly assess the measurement properties of the currently available questionnaires. Until high quality studies are available, we recommend using these questionnaires with caution. There is no need for the development of new neck-specific questionnaires until the current questionnaires have been adequately assessed.

    An attempt has been made to develop water quality index (WQI), using six water quality parameters pH, dissolved oxygen, biochemical oxygen demand, electrical conductivity, nitrate nitrogen and total coliform measured at three different stations along the Sabarmati river basin from the year 2005 to 2008. Rating scale is developed based on the tolerance limits of inland waters and health point of view. Weighted arithmetic water quality index method was used to find WQI along the stretch of the river basin. It was observed from this study that the impact of human activity and sewage disposal in the river was severe on most of the parameters. The station located in highly urban area showed the worst water quality followed by the station located in moderately urban area and lastly station located in a moderately rural area. It was observed that the main cause of deterioration in water quality was due to the high anthropogenic activities, illegal discharge of sewage and industrial effluent, lack of proper sanitation, unprotected river sites and urban runoff.

    This study aimed to evaluate the reliability and validity of the Korean version of the Mini-Sleep Questionnaire-Insomnia in Korean college students. A total of 470 students from six nursing colleges in South Korea participated in the study. The translation and linguistic validation of the Mini-Sleep Questionnaire-Insomnia was performed based on guidelines. The Pittsburgh Sleep Quality Index and the Perceived Stress Scale were used to validate the measure. Cronbach α, item-total correlation for internal consistency reliability and intraclass correlation coefficient for test-retest reliability were evaluated. Exploratory factor analysis for construct validity, Pearson's correlation with the Pittsburgh Sleep Quality Index and the Perceived Stress Scale for concurrent validity, and the receiver operating character curve for predictive validity were assessed. The 4-item Mini-Sleep Questionnaire-Insomnia had a Cronbach α of .69 and the item-total correlations were higher than .30. Cronbach α increased to .73 if the item assessing the use of sleeping pills and tranquilizers was deleted. This item had marked skewness and kurtosis issues. Factor analysis indicated unidimensionality, explaining 53.0% of the total variance. The measure showed high test-retest reliability (i.e., intraclass correlation coefficient = .84), acceptable concurrent validity (r with the Pittsburg Sleep Quality Index = .69; r with the Perceived Stress Scale = .31) and predictive validity [area under curve = .85; 95% confidence interval (0.81, 0.90)]. The Mini-Sleep Questionnaire-Insomnia showed acceptable reliability and validity. Yet, the limited distribution in sleep medications warrants further evaluations in the clinical population.

    To critically review conceptual frameworks for available patient-reported outcome (PRO) questionnaires in men having radical prostatectomy (RP), psychometrically evaluate each questionnaire, and identify whether each is appropriate for use at the level of the individual patient. We searched PubMed, the Reports and Publications database of the University of Oxford Patient-Reported Outcomes Measurement Group and the website of the International Consortium for Health Outcomes Measurement (ICHOM) for psychometric reviews of prostate cancer-specific PRO questionnaires. From these we identified relevant questionnaires and critically appraised the conceptual content, guided by the Wilson and Cleary framework and psychometric properties, using well established criteria. The searches found four reviews and one recommendation paper. We identified seven prostate cancer-specific PROs: the Expanded Prostate Cancer Index Composite-26 (EPIC-26), Expanded Prostate Cancer Index Composite-50 (EPIC-50), University of California-Los Angeles Prostate Cancer Index (UCLA-PCI), Functional Assessment of Cancer Therapy - Prostate Cancer Subscale (FACT-P PCS), European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - prostate specific 25-item (EORTC QLQ-PR25), Prostate Cancer - Quality of Life (PC-QoL), and Symptom Tracking and Reporting (STAR). Six out of seven measures purported to measure health-related quality of life (HRQL), but items focused strongly on urinary and sexual symptoms/functioning. The remaining questionnaire (STAR) claimed to assess functional recovery after RP. The psychometric evidence for these questionnaires was incomplete and variable in quality; none had evidence that they were appropriate for use with individual patients. Several questionnaires provide the basis of measures of urinary and/or sexual symptoms/functioning. Further work should explore other aspects of HRQL that are important for men having RP.

    Objective To develop and validate the Adult Hypopituitarism Questionnaire (AHQ) as a disease-specific, self-administered questionnaire for evaluation of quality of life (QOL) in adult patients with hypopituitarism. Methods We developed and validated this new questionnaire, using a standardized procedure which included item development, pilot-testing and psychometric validation. Of the patients who participated in psychometric validation, those whose clinical conditions were judged to be stable were asked to answer the survey questionnaire twice, in order to assess test-retest reliability. Results Content validity of the initial questionnaire was evaluated via two pilot tests. After these tests, we made minor revisions and finalized the initial version of the questionnaire. The questionnaire was constructed with two domains, one psycho-social and the other physical. For psychometric assessment, analyses were performed on the responses of 192 adult patients with various types of hypopituitarism. The intraclass correlations of the respective domains were 0.91 and 0.95, and the Cronbach’s alpha coefficients were 0.96 and 0.95, indicating adequate test-retest reliability and internal consistency for each domain. For known-group validity, patients with hypopituitarism due to hypothalamic disorder showed significantly lower scores in 11 out of 13 sub-domains compared to those who had hypopituitarism due to pituitary disorder. Regarding construct validity, the domain structure was found to be almost the same as that initially hypothesized. Exploratory factor analysis (n = 228) demonstrated that each domain consisted of six and seven sub-domains. Conclusion The AHQ showed good reliability and validity for evaluating QOL in adult patients with hypopituitarism. PMID:22984490

    Rheumatologists and other caregivers can learn from patients’ experiences with the quality of care that can be measured with the CQ-index Rheumatoid Arthritis (CQ-index RA) survey. Patients with RA (n = 590) received this survey were they rated their actual experiences and what they find important in rheumatic healthcare. Descriptive analyses and psychometric methods were used to test the reliability. The response rate was 69%. The items in the pilot instrument could be grouped into 10 scales (α ranged from 0.77 to 0.94). The most important quality aspects according to patients concerned the alertness when prescribing medication. Providing patients with information on a special website of the hospital about RA was the highest quality improvement aspect. The results of this study show that the CQ-index RA is a reliable instrument for quality assessment from the patients’ perspective. The instrument provides rheumatologists and other caregivers with feedback for service improvement initiatives.

    To provide an up-to-date assessment of the quality of commonly recommended questionnaires for measuring symptom severity and quality of life in women with urinary incontinence and also to consider their application to practice. Urinary incontinence is a common problem for women. In addition to various physical symptoms, there is a known effect on quality of life. Psychometrically robust questionnaires are reported to be the best way to measure an individual's perceptions of symptom severity and quality of life, and a number of different ones are recommended for use in international and national guidance, which can be confusing for clinicians. Moreover, there are concerns over the applicability of some of these instruments in clinical practice. An evaluative review was carried out examining selected questionnaires measuring symptom severity and/or quality of life. Selection of questionnaires for inclusion in the review was based on the recommendations of evidence-based guidance, followed by systematic scrutiny of the characteristics of the individual recommended questionnaires. Thirteen questionnaires were included in the review, of which three appeared to 'outperform' the remainder in terms of their psychometric properties and other characteristics. This review provides the most up-to-date and comprehensive analysis of the quality and applicability of the included questionnaires and offers the practitioner advice on which to select for use in practice. This review aims to help the practitioner choose a questionnaire based on a sound evaluation of the quality of the questionnaire and its applicability to the clinical setting. © 2013 John Wiley & Sons Ltd.

    ABSTRACT OBJECTIVE: To develop a Diet Quality Index Adapted for Pregnant Women (IQDAG) and to evaluate its relation with the characteristics of women treated at the Brazilian Unified Health System. METHODS: The data on food intake come from a cross-sectional study carried out with 785 adult pregnant women in the city of Ribeirão Preto, state of São Paulo, Brazil, between 2011 and 2012. The index was based on the recommendations of the Brazilian Ministry of Health, previous national dietary indexes, and the new Dietary Guidelines for the Brazilian Population. We used the ANOVA, Kruskal-Wallis, and chi-square tests to describe the quality of the diet according to the characteristics of the mother. RESULTS: The IQDAG has nine components, and it is represented by three food groups (in servings/1,000 kcal), five nutrients, and a moderator component. A high proportion of pregnant women reached the maximum score for the components of legumes and vegetables. However, few women reached the maximum score for consumption of fresh fruits, fiber, omega-3, calcium, folate, iron, and ultra-processed foods. We verified a better quality of diet among older and eutrophic pregnant women who reported practicing more physical activity and taking dietary supplements. We also observed the highest index score among women with higher intake of carbohydrates, proteins, vitamins C, E, and A, and minerals calcium, folate, and iron, as well as among those with lower intake of total fats and saturated fats. CONCLUSIONS: This dietary index is unprecedented in incorporating the recommendation of the new Dietary Guidelines for the Brazilian Population regarding the moderation of the consumption of ultra-processed foods. It was useful in evaluating the quality of the diet of pregnant women and we verified a higher score among older and eutrophic women who reported a healthy lifestyle. Strategies are needed to promote a higher consumption of fresh fruits, foods high in fiber, omega-3, calcium

    To translate and validate the Pittsburgh Sleep Quality Index (PSQI), a standardized self-administered questionnaire for the assessment of subjective sleep quality into the Urdu language. Validation study. Mayo Hospital, Lahore, from March to April 2012. The PSQI was translated into Urdu following standard guidelines. The final Urdu version (PSQI-U) was administered to 200 healthy volunteers comprising medical students, nursing staff and doctors. Inter-item correlation was assessed by calculating Cronbach alpha. Correlation of component scores with global score was assessed by calculating Spearman correlation coefficient. Correlation between global PSQI-U scores at baseline with global scores for each PSQI-U and PSQI-E at 4-week interval was evaluated by calculating Spearman correlation coefficient. Moreover, scores on individual items of the scale at baseline were compared with respective scores after 4-week by t-test. One hundred and eighty five (185) participants completed the PSQI-U at baseline. The Cronbach alpha for PSQI-U was 0.56. Scores on individual components of the PSQI-U and composite scores were all highly correlated with each other (all p-values < 0.01). Composite scores for PSQI-U at baseline and PSQI-E at 4-week interval were also highly correlated with each other (Spearman correlation coefficient 0.74, p-value < 0.01) indicating good linguistic interchangeability. Composite scores for PSQI-U at baseline and at 4-week interval were positively correlated with each other (Spearman correlation coefficient 0.70, p < 0.01) indicating good test-retest reliability. The PSQI-U is a valid and reliable instrument for the assessment of sleep quality. It shows good linguistic interchangeability and test-retest reliability in comparison to the original English version when applied to individuals who speak the Urdu language. The PSQI-U can be a tool either for clinical management or research.

    In photon brachytherapy (BT), experimental dosimetry is needed to verify treatment plans if planning algorithms neglect varying attenuation, absorption or scattering conditions. The detector's response is energy dependent, including the detector material to water dose ratio and the intrinsic mechanisms. The local mean photon energy E¯(r) must be known or another equivalent energy quality parameter used. We propose the brachytherapy photon radiation quality indexQ(BT)(E¯), to characterize the photon radiation quality in view of measurements of distributions of the absorbed dose to water, Dw, around BT sources. While the external photon beam radiotherapy (EBRT) radiation quality index Q(EBRT)(E¯)=TPR10(20)(E¯) is not applicable to BT, the authors have applied a novel energy dependent parameter, called brachytherapy photon radiation quality index, defined as Q(BT)(E¯)=Dprim(r=2cm,θ0=90°)/Dprim(r0=1cm,θ0=90°), utilizing precise primary absorbed dose data, Dprim, from source reference databases, without additional MC-calculations. For BT photon sources used clinically, Q(BT)(E¯) enables to determine the effective mean linear attenuation coefficient μ¯(E) and thus the effective energy of the primary photons Eprim(eff)(r0,θ0) at the TG-43 reference position Pref(r0=1cm,θ0=90°), being close to the mean total photon energy E¯tot(r0,θ0). If one has calibrated detectors, published E¯tot(r) and the BT radiation quality correction factor [Formula: see text] for different BT radiation qualities Q and Q0, the detector's response can be determined and Dw(r,θ) measured in the vicinity of BT photon sources. This novel brachytherapy photon radiation quality indexQ(BT) characterizes sufficiently accurate and precise the primary photon's penetration probability and scattering potential. Copyright © 2016.

    Individuals with Parkinson's disease (PD) may exhibit some degree of change in swallowing dynamics during the course of the disease. These changes can affect their physical, functional and emotional quality of life. To develop a quality of life and swallowing questionnaire for individuals with PD. The first version of the questionnaire comprised 29 items taken from the accounts of 50 patients treated over a 2-month period at Sarah Hospital in Salvador, Bahia, Brazil. A committee of 10 experts in the field analyzed the content and reduced the questionnaire to 28 questions. The questionnaire was then administered to 140 PD patients and 47 healthy individuals. A factor analysis of the items guided the drafting of the final questionnaire, which consisted of 19 items grouped into four factors, encompassing physical, functional and emotional aspects. A test-retest assessment was conducted with 44 individuals with PD. The internal consistency, estimated by the mean of Cronbach's alpha coefficient, varied between 0.71 (domain 3) and 0.94 (domain 1) in the test and between 0.69 (domain 3) and 0.95 (domain 1) in the retest. The correlation coefficient in the test/retest comparison was high and significant, demonstrating that the measurement was stable. A significant difference was observed between the PD group and the comparison group. The questionnaire developed is a valid, statistically appropriate and clinically effective self-administered instrument for individuals with PD. © 2018 Royal College of Speech and Language Therapists.

    Background: Along with the rapid growth of technology its related tools such as computer, monitors and video display terminals (VDTs) grow as well. Based on the studies, the most common complaint reported is of the VDT users. Methods: This study attempts to design a proper tool to assess the visual fatigue of the VDT users. First draft of the questionnaire was prepared after a thorough study on the books, papers and similar questionnaires. The validity and reliability of the questionnaire was confirmed using the content validity index (CVI) beside that of the Cronbach's Coefficient Alpha. Then, a cross-sectional study was carried out on 248 of the VDT users in different professions. A theoretical model with four categories of symptoms of visual fatigue was derived from the previous studies and questionnaires. Having used the AMOS16 software, the construct validity of the questionnaire was evaluated using the confirmatory factor analysis. The correlation co-efficiency of the internal domains was calculated using the SPSS 11.5 software. To assess the quality check index and determining the visual fatigue levels, visual fatigue of the VDT users was measured by the questionnaire and visual fatigue meter (VFM) device. Cut-off points were identified by receiver operating characteristic curves. Results: CVI and reliability co-efficiency were both equal to 0.75. Model fit indices including root mean of squared error approximation, goodness of fit index and adjusted goodness of fit index were obtained 0.026, 0.96 and 0.92 respectfully. The correlation between the results measured with the questionnaire and VFM-90.1 device was −0.87. Cut-off points of the questionnaire were 0.65, 2.36 and 3.88. The confirmed questionnaire consists of four main areas: Eye strain (4 questions), visual impairment (5 questions) and the surface impairment of the eye (3 questions) and the out of eye problems (3 questions). Conclusions: The visual fatigue questionnaire contains 15 questions and

    To assess the acceptability, reliability, validity, and responsiveness of the Chinese Asthma Quality of Life Questionnaire (C-AQLQ) in a sample of Chinese asthma patients. The C-AQLQ and Short Form 36 Health Survey (SF-36) scales were administered to patients at baseline and 3 months later. Asthma severity condition and lung function were evaluated. Necessary data were gathered to assess the psychometric properties such as the feasibility, internal consistency, test-retest reliability, structural validity, discriminant validity, convergent validity, and responsiveness of the C-AQLQ. One hundred and thirty-seven patients completed the investigation. The Cronbach's alpha coefficient for the total scale was 0.96. Factor analysis yielded five factors that generally corresponded to the five proposed subscales. Patients with mild asthma reported higher scores than patients with moderate/severe asthma on all subscales other than environmental stimuli. Lung function measurement and the asthma severity score correlated significantly with domains of the C-AQOL but with fewer domains of the SF-36. The questionnaire detected within-subject changes in patients' asthma status during follow-up. Results indicated preliminary support that the C-AQLQ is a reliable, valid, discriminating, and responsive measure of quality of life in Chinese asthma patients. It is more sensitive than the generic SF-36 in detecting differences in asthma severity.

    Study Design  Retrospective reliability and validity study. Objective  To validate a recently translated Russian language version of the Oswestry Disability Index (R-ODI) using standardized methods detailed from previous validations in other languages. Methods  We included all subjects who were seen in our spine surgery clinic, over the age of 18, and fluent in the Russian language. R-ODI was translated by six bilingual people and combined into a consensus version. R-ODI and visual analog scale (VAS) questionnaires for leg and back pain were distributed to subjects during both their initial and follow-up visits. Test validity, stability, and internal consistency were measured using standardized psychometric methods. Results Ninety-seven subjects participated in the study. No change in the meaning of the questions on R-ODI was noted with translation from English to Russian. There was a significant positive correlation between R-ODI and VAS scores for both the leg and back during both the initial and follow-up visits ( p  < 0.01 for all). The instrument was shown to have high internal consistency (Cronbach α = 0.82) and moderate test-retest stability (interclass correlation coefficient = 0.70). Conclusions  The R-ODI is both valid and reliable for use among the Russian-speaking population in the United States.

    The aim of this study was to define a new indicator for the quality of wastewaters that are released into the environment. A quality index is proposed for wastewater samples in terms of the inertness of wastewater samples toward enzyme activity. This involves taking advantage of the sensitivity of enzymes to pollutants that may be present in the waste samples. The effect of wastewater samples on the rate of a number of different enzyme-catalyzed reactions was measured, and the results for all the selected enzymes were analyzed in an integrated fashion (multi-enzymatic sensor). This approach enabled us to define an overall quality index, the "Impact on Enzyme Function" (IEF-index), which is composed of three indicators: i) the Synoptic parameter, related to the average effect of the waste sample on each component of the enzymatic sensor; ii) the Peak parameter, related to the maximum effect observed among all the effects exerted by the sample on the sensor components; and, iii) the Interference parameter, related to the number of sensor components that are affected less than a fixed threshold value. A number of water based samples including public potable tap water, fluids from urban sewage systems, wastewater disposal from leather, paper and dye industries were analyzed and the IEF-index was then determined. Although the IEF-index cannot discriminate between different types of wastewater samples, it could be a useful parameter in monitoring the improvement of the quality of a specific sample. However, by analyzing an adequate number of waste samples of the same type, even from different local contexts, the profile of the impact of each component of the multi-enzymatic sensor could be typical for specific types of waste. The IEF-index is proposed as a supplementary qualification score for wastewaters, in addition to the certification of the waste's conformity to legal requirements. Copyright © 2013 Elsevier Ltd.

    In the field of intellectual disabilities (ID), the quality of life concept has been developing rapidly in Chinese societies including Hong Kong, mainland China and Taiwan. However, there is a lack of locally validated instruments to measure the quality of life of people with ID. The study reported in this paper attempted to validate the Chinese Quality of Life Questionnaire - Intellectual Disabilities adapted from the Quality of Life Questionnaire developed by Schalock & Keith. People with mild/moderate ID aged 15 years or above were recruited from special schools, skills centres, community service units and residential units in different regions of Hong Kong. A number of procedures were followed including reliability tests, factor analysis, content validity and construct validity. A total of 359 participants were recruited for the study. Factor analysis was conducted according to the rotated component matrix method, in which 23 items were extracted from the original 40-item version of the Quality of Life Questionnaire and three domains (renamed satisfaction, competence and daily choice making/interpersonal relations) were observed. The items in each domain were shown to have factor loadings ranging from 0.42 to 0.90. Construct validity tests indicated the positive nature of the relationship between earnings, and that self-determination and social interaction increase with more independent living environments and less segregated work environments achieving higher scores (P<0.000, P<0.01 and P<0.05 respectively). The scale also achieved a good degree of reliability (Cronbach's α=0.79). Initial validity tests indicated that the Chinese Quality of Life Questionnaire - Intellectual Disabilities may be a useful instrument for measuring the quality of life of Chinese people with ID. Cultural issues are discussed and recommendations for future research and service development are made. © 2011 The Authors. Journal of Intellectual Disability Research © 2011 Blackwell

    Quality of life (QoL) assessment questionnaires can be burdensome to advanced cancer patients, thus necessitating the need for shorter assessment instruments than traditionally available. We compare three shortened QoL questionnaires in regards to their characteristics, validity, and reliability. A literature search was conducted to identify studies that employed or discussed three abridged QoL questionnaires: the European Organization for Research and Treatment of Cancer Quality of Life Core 15-Palliative Care (EORTC QLQ-C15-PAL), the Functional Assessment of Cancer Therapy-General-7 (FACT-G7), and the Functional Assessment of Chronic Illness Therapy-Palliative Care-14 (FACIT-PAL-14). Articles that discussed questionnaire length, intended use, scoring procedure, and validation were included. The 7-item FACT-G7 is the shortest instrument, whereas the EORTC QLQ-C15-PAL and the FACIT-PAL-14 contain 14 and 15 items, respectively. All three questionnaires have similar recall period, item organization, and subscale components. Designed as core questionnaires, all three maintain content and concurrent validity of their unabridged original questionnaires. Both the EORTC QLQ-C15-PAL and the FACT-G7 demonstrate good internal consistency and reliability, with Cronbach's α ≥0.7 deemed acceptable. The developmental study for the FACIT-PAL-14 was published in 2013 and subsequent validation studies are not yet available. The EORTC QLQ-C15-PAL and the FACT-G7 were found to be reliable and appropriate for assessing health-related QoL issues-the former for palliative cancer patients and the latter for advanced cancer patients receiving chemotherapy. Conceptually, the FACIT-PAL-14 holds promise to cover social and emotional support issues that are not completely addressed by the other two questionnaires; however, further validation is needed.

    Fibromyalgia is a painful syndrome characterized by widespread chronic pain and associated symptoms with a negative impact on quality of life. Considering the subjectivity of quality of life measurements, the aim of this study was to verify the discriminating power of two quality of life questionnaires in patients with fibromyalgia: the generic Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the specific Fibromyalgia Impact Questionnaire (FIQ). A cross-sectional study was conducted on 150 participants divided into Fibromyalgia Group (FG) and Control Group (CG) (n=75 in each group). The participants were evaluated using the SF-36 and the FIQ. The data were analyzed by the Student t-test (α=0.05) and inferential analysis using the Receiver Operating Characteristics (ROC) Curve--sensitivity, specificity and area under the curve (AUC). The significance level was 0.05. The sample was similar for age (CG: 47.8 ± 8.1; FG: 47.0 ± 7.7 years). A significant difference was observed in quality of life assessment in all aspects of both questionnaires (p<0.05). Higher sensibility, specificity and AUC were obtained by the FIQ (96%, 96%, 0.985, respectively), followed by the SF-36 (88%, 89% and 0.948 AUC). The FIQ presented the highest sensibility, specificity and AUC showing the most discriminating power. However the SF-36 is also a good instrument to assess quality of life in fibromyalgia patients, and we suggest that both should be used in parallel because they evaluate relevant and complementary aspects of quality of life.

    To identify the questionnaires used to assess refractive surgery outcomes, assess the available questionnaires in regard to their psychometric properties, validity, and reliability, and evaluate the performance of the available questionnaires in measuring refractive surgery outcomes. An extensive literature search was done on PubMed, MEDLINE, Scopus, CINAHL, Cochrane, and Web of Science databases to identify articles that described or used at least one questionnaire to assess refractive surgery outcomes. The information on content quality, validity, reliability, responsiveness, and psychometric properties was extracted and analyzed based on an extensive set of quality criteria. Eighty-one articles describing 27 questionnaires (12 refractive error-specific, including 4 refractive surgery-specific, 7 vision-but-non-refractive, and 8 generic) were included in the review. Most articles (56, 69.1%) described refractive error-specific questionnaires. The Quality of Life Impact of Refractive Correction (QIRC), the Quality of Vision (QoV), and the Near Activity Visual Questionnaire (NAVQ) were originally constructed using Rasch analysis; others were developed using the Classical Test Theory. The National Eye Institute Refractive Quality of Life questionnaire was the most frequently used questionnaire, but it does not provide a valid measurement. The QoV, QIRC, and NAVQ are the three best existing questionnaires to assess visual symptoms, quality of life, and activity limitations, respectively. This review identified three superior quality questionnaires for measuring different aspects of quality of life in refractive surgery. Clinicians and researchers should choose a questionnaire based on the concept being measured with superior psychometric properties. [J Refract Surg. 2017;33(6):416-424.].

    Background The purpose of the present study was to assess the vision-related quality of life (QOL) of visually impaired patients using the Japanese 11-item National Eye Institute Visual Function Questionnaire (VFQ-J11). Comparisons with the 25-item version (VFQ-25) and the EuroQoL Index using a large group of patients with various degrees of impairments and various causative diseases were performed. Methods A total of 232 visually impaired Japanese patients were recruited from six ophthalmology departments in Japan. Information on ophthalmic findings and patient backgrounds was collected, and information on QOL and utility assessments was collected from the patients by means of survey questionnaires. Results The average age of patients was 69.6±14.3 years. Both the vision-related QOL scores (VFQ-25 composite and VFQ-J11) were significantly associated with better and worse visual acuity (VA) in visually impaired subjects (all P<0.01). VFQ-J11 was comparable to VFQ-25 regardless of causative diseases. VFQ-25 composite and the VFQ-J11 scores were concurrently associated with a range of systemic medical disorders. EuroQoL Index had a significant association with better eye VA (P<0.01), but not with worse eye VA, or any systemic disorders. Conclusion VFQ-J11 provides valid data on vision-related QOL and is less of a burden for patients with vision problems. PMID:27784982

    The spatial and temporal variation of water quality in the urban area of the Puebla Valley aquifer was evaluated using historical and present data obtained during this investigation. The current study assessed water quality based on the Water Quality Index developed by the Canadian Council of Ministers of the Environment (CCME-WQI), which provides a mathematical framework to evaluate the quality of water in combination with a set of conditions representing quality criteria, or limits. This index is flexible regarding the type and number of variables used by the evaluation given that the variables of interest are selected according to the characteristics and objectives of development, conservation and compliance with regulations. The CCME-WQI was calculated using several variables that assess the main use of the wells in the urban area that is public supply, according to criteria for human use and consumption established by Mexican law and international standards proposed by the World Health Organization. The assessment of the index shows a gradual deterioration in the quality of the aquifer over time, as the amount of wells with excellent quality have decreased and those with lower index values (poor quality) have increased throughout the urban area of the Puebla Valley aquifer. The parameters affecting groundwater quality are: total dissolved solids, sulfate, calcium, magnesium and total hardness.

    The impact of strabismus on visual function, self-image, self-esteem, and social interactions decrease health-related quality of life (HRQoL).The purpose of this study was to evaluate and refine the adult strabismus quality of life questionnaire (AS-20) by using Rasch analysis among Chinese adult patients with strabismus. We evaluated the fitness of the AS-20 with Rasch model in Chinese population by assessing unidimensionality, infit and outfit, person and item separation index and reliability, response ordering, targeting and differential item functioning (DIF). The overall AS-20 did not demonstrate unidimensional; however, it was achieved separately in the two Rasch-revised subscales: the psychosocial subscale (11 items) and the function subscale (9 items). The features of good targeting, optimal item infit and outfit, and no notable local dependence were found for each of the subscales. The rating scale was appropriate for the psychosocial subscale but a reduction to four response categories was required for the function subscale. No significant DIF were revealed for any demographic and clinical factors (e.g., age, gender, and strabismus types). The AS-20 was demonstrated by Rasch analysis to be a rigorous instrument for measuring health-related quality of life in Chinese strabismus patents if some revisions were made regarding the subscale construct and response options.

    Physical functioning is a core outcome domain to be measured in nonspecific low back pain (NSLBP). A panel of experts recommended the Roland-Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI) to measure this domain. The original 24-item RMDQ and ODI 2.1a are recommended by their developers. The purpose of this study was to evaluate whether the 24-item RMDQ or the ODI 2.1a has better measurement properties than the other to measure physical functioning in adult patients with NSLBP. Bibliographic databases (MEDLINE, Embase, CINAHL, SportDiscus, PsycINFO, and Google Scholar), references of existing reviews, and citation tracking were the data sources. Two reviewers selected studies performing a head-to-head comparison of measurement properties (reliability, validity, and responsiveness) of the 2 questionnaires. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used to assess the methodological quality of these studies. The studies' characteristics and results were extracted by 2 reviewers. A meta-analysis was conducted when there was sufficient clinical and methodological homogeneity among studies. Nine articles were included, for a total of 11 studies assessing 5 measurement properties. All studies were classified as having poor or fair methodological quality. The ODI displayed better test-retest reliability and smaller measurement error, whereas the RMDQ presented better construct validity as a measure of physical functioning. There was conflicting evidence for both instruments regarding responsiveness and inconclusive evidence for internal consistency. The results of this review are not generalizable to all available versions of these questionnaires or to patients with specific causes for their LBP. Based on existing head-to-head comparison studies, there are no strong reasons to prefer 1 of these 2 instruments to measure physical functioning in patients with NSLBP, but studies of higher

    Background and Aims: Acne vulgaris affects about 85% of adolescents, often extending into adulthood. Psychosocial impact of acne on health-related quality of life (QoL) has been identified, but it remains under-evaluated, especially in Indian patients. This study was aimed to assess the impact of acne and its sequelae on the QoL. Materials and Methods: This was a hospital-based, prospective, cross-sectional study done between June and November 2014 on 114 consenting patients above 15 years of age with acne vulgaris. Acne vulgaris and its sequelae were graded, and QoL was assessed by using Dermatology Life Quality Index (DLQI) questionnaire. Results: Most cases (64%) were between 15 and 20 years. Females (57%) outnumbered males. Facial lesions (61.4%) and grade II acne were most common. Mean DLQI score was 7.22. DLQI scores were statistically influenced by the age of the patient, duration and grade of acne, acne scar, and postacne hyperpigmentation. Conclusion: This study showed significant impairment of QoL in acne patients. Assurance and counseling along with early treatment of acne vulgaris are important to reduce disease-related psychosocial sequelae and increase the efficacy of treatment. PMID:27057015

    Several generic questionnaires have been used to measure quality of life in patients with Osteoarthritis (OA) since few instruments have been developed specifically for OA and none was developed for Spanish speaking patients. The purpose of the study was to validate and adapt to Spanish the French questionnaire AMICAL to measure quality of life in patients with hip and knee OA. Transversal, analytical study. The validation process was performed in phases: translation from French to Spanish, translated version analysis by a multidisciplinary expert team, application of a pilot test to patients to evaluate grammatical and content equivalence, blind back translation, and analysis. The questionnaire was applied to hip and knee OA patients, together with the SF-36 questionnaire, as well as the WOMAC and the Lequesne indexes. The reproducibility was evaluated applying the questionnaire after 72hours. The clinimetric analysis was calculated with SPSS 16.0. One hundred patients with hip OA and 100 patients with knee OA, radiological stages ii-iii, were included to evaluate homogeneity. Sixty-five patients with hip OA and 65 patients with knee OA were included to evaluate consistency. The final sample included 100 hip and 100 patients knee OA patients to estimate homogeneities and 65 patients were evaluated to estimate consistency. Mean (SD) age of patients with hip and knee OA, was 56.34 ± 13 and 60.1 ± 9.2, respectively. Sixty seven percent and 79.8% were female, respectively. Cronbach' alpha for AMICAL was 0.946 and 0.999, for hip OA and knee OA, respectively; and test-retest reliability using the intraclass correlation coefficients was 0.979 and 0.998, respectively. There was also a significant correlation with all the instruments (P<.05), except with the Lequesne index (r-0.383). The Spanish version of AMICAL questionnaire keep the clinimetric properties, homogeneity, and consistency, and has a good correlation with other instruments. Consequently, it is reliable

    Several so-called casting indices are available for objective evaluation of plaster cast quality. The present study sought to investigate four of these indices (gap index, padding index, Canterbury index, and three-point index) as compared to a reference standard (cast index) for evaluation of plaster cast quality after closed reduction of pediatric displaced distal forearm fractures. Forty-three radiographs from patients with displaced distal forearm fractures requiring manipulation were reviewed. Accuracy, sensitivity, specificity, false-positive probability, false-negative probability, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were calculated for each of the tested indices. Comparison among indices revealed diagnostic agreement in only 4.7% of cases. The strongest correlation with the cast index was found for the gap index, with a Spearman correlation coefficient of 0.94. The gap index also displayed the best agreement with the cast index, with both indices yielding the same result in 79.1% of assessments. When seeking to assess plaster cast quality, the cast index and gap index should be calculated; if both indices agree, a decision on quality can be made. If the cast and gap indices disagree, the padding index can be calculated as a tiebreaker, and the decision based on the most frequent of the three results. Calculation of the three-point index and Canterbury index appears unnecessary. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Our aim was to translate the Quality of Life in Essential Tremor Questionnaire (QUEST) advanced by Troster (2005) and to analyse the validity and reliability of this questionnaire. Two hundred twelve consecutive patients with essential tremor (ET) and forty-three control subjects were included in the study. Permission for the translation and validation of the QUEST scale was obtained. The translation was performed according to the guidelines provided by the publisher. After the translation, the final version of the scale was administered to both groups to determine its reliability and validity. The QUEST Physical, Psychosocial, communication, Hobbies/leisure and Work/finance scores were 0.967, 0.968, 0.933, 0.964 and 0.925, respectively. There were good correlations between each of the QUEST scores that were indicative of good internal consistency. Additionally, we observed that all of the QUEST scores were most strongly related to the right and left arms (p=0.0001). However, we observed that all of the QUEST scores were weakly related to the voice, head and right leg (p=0.0001). These findings support the notion that the Turkish version of the Quality of Life in Essential Tremor (QUEST) questionnaire is a valid and reliable tool for the assessment of the quality of life of patients with ET.

    Objectives. An environmental quality index (EQI) for all counties in the United States is under development to explore the relationship between environmental insults and human health. The EQI is potentially useful for investigators researching health disparities to account for other concurrent environmental conditions. This article focused on the identification and assessment of data sources used in developing the EQI. Data source strengths, limitations, and utility were addressed. Methods. Five domains were identified that contribute to environmental quality: air, water, land, built, and sociodemographic environments. An inventory of possible data sources was created. Data sources were evaluated for appropriate spatial and temporal coverage and data quality. Results. The overall data inventory identified multiple data sources for each domain. From the inventory (187 sources, 617 records), the air, water, land, built environment, and sociodemographic domains retained 2, 9, 7, 4, and 2 data sources for inclusion in the EQI, respectively. However, differences in data quality, geographic coverage, and data availability existed between the domains. Conclusions. The data sources identified for use in the EQI may be useful to researchers, advocates, and communities to explore specific environmental quality questions. PMID:21836111

    In this study we describe the translation and psychometric evaluation of the Dutch Individualized Neuromuscular Quality of Life (INQoL) questionnaire. Backward and forward translation of the questionnaire was executed, and psychometric properties were assessed on the basis of reliability and validity. Two hundred six patients were included in the study. Reliability analyses resulted in Cronbach alpha values of >0.70 for all subdomains. Known-group validity showed a significant correlation between INQoL scores and severity as well as age for the majority of subdomains. Item-total correlation for overall quality of life was satisfactory. Concurrent validity with the SF-36 and EQ-5D was good (range of Spearman correlation coefficients -0.43 to -0.76). This study resulted in a questionnaire that is appropiate for use in the Dutch-speaking population to measure quality of life among patients with a wide variety of muscle disorders.

    Assessing physician performance is important for the purposes of measuring and improving quality of service and reducing healthcare delivery costs. In recent years, physician performance scorecards have been used to provide feedback on individual measures; however, one key challenge is how to develop a composite quality index that combines multiple measures for overall physician performance evaluation. A controversy arises over establishing appropriate weights to combine indicators in multiple dimensions, and cannot be easily resolved. In this study, we proposed a generic unsupervised learning approach to develop a single composite index for physician performance assessment by using non-negative principal component analysis. We developed a new algorithm named iterative quadratic programming to solve the numerical issue in the non-negative principal component analysis approach. We conducted real case studies to demonstrate the performance of the proposed method. We provided interpretations from both statistical and clinical perspectives to evaluate the developed composite ranking score in practice. In addition, we implemented the root cause assessment techniques to explain physician performance for improvement purposes. Copyright © 2012 John Wiley & Sons, Ltd.

    Quality of life (QOL) in children with cerebral palsy (CP) needs to be measure by CP-specific questionnaire. CP-QOL questionnaire is being used for this purpose. The aim is to determine the QOL in Indian children with CP using CP-QOL questionnaire and to correlate QOL scores with demographic details of the patient. Subjects were parents of 50 children (4-12 years) attending child development center of Guru Teg Bahadur Hospital were enrolled. The parent-proxy version of the CP-QOL questionnaire translated into Hindi was administered by one author. Scoring and analysis were performed as per specified method. Cronbach's alpha was calculated for each domain for validation. Effect of clinical and demographic profile on QOL was analyzed. CP-QOL questionnaire was administered to 50 parents of CP children (32 males, 18 females). The overall QOL score of the children studied was computed to be 38.29 ± 5.2. Age and maternal education had a significant bearing on the QOL of the children ( P < 0.05). Type of CP, gender, and epilepsy did not affect the QOL significantly ( P > 0.05). Good internal consistency and reliability were found in the domains of social well-being and acceptance, functioning, participation, and physical health (Cronbach's alpha >0.7). Access to services, pain, and impact of disability and family health showed a weak correlation with Cronbach's alpha <0.7. QOL in children with CP was compromised. The CP-QOL questionnaire can be used to measure QOL in Indian children with CP.

    The purposes of the study were to investigate and evaluate the differences detected by the patients between the traditional orthognathic approach and the surgery-first one in terms of level of satisfaction and quality of life. A total of 30 patients who underwent orthognathic surgery for correction of malocclusions were selected and included in this study. Fifteen patients were treated with the conventional orthognathic surgery approach, and 15 patients with the surgery-first approach. Variables were assessed through the Orthognathic Quality of Life Questionnaire and the Oral Health Impact Profile questionnaire and analyzed with 2-way repeated-measures analysis of variance. The results showed significant differences in terms of the Orthognathic Quality of Life Questionnaire (P <0.001) and the Oral Health Impact Profile (P <0.001) scores within groups between the first and last administrations of both questionnaires. Differences in the control group between first and second administrations were also significant. Questionnaire scores showed an immediate increase of quality of life after surgery in the surgery-first group and an initial worsening during orthodontic treatment in the traditional approach group followed by postoperative improvement. This study showed that the worsening of the facial profile during the traditional orthognathic surgery approach decompensation phase has a negative impact on the perception of patients' quality of life. Surgeons should consider the possibility of a surgery-first approach to prevent this occurrence. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc.

    The impact of sarcopenia on quality of life is currently assessed by generic tools. However, these tools may not detect subtle effects of this specific condition on quality of life. The aim of this study was to develop a sarcopenia-specific quality of life questionnaire (SarQoL, Sarcopenia Quality of Life) designed for community-dwelling elderly subjects aged 65 years and older. Participants were recruited in an outpatient clinic in Liège, Belgium. Sarcopenic subjects aged 65 years or older. The study was articulated in the following four stages: (i) Item generation-based on literature review, sarcopenic subjects' opinion, experts' opinion, focus groups; (ii) Item reduction-based on sarcopenic subjects' and experts' preferences; (iii) Questionnaire generation-developed during an expert meeting; (iv) Pretest of the questionnaire-based on sarcopenic subjects' opinion. The final version of the questionnaire consists of 55 items translated into 22 questions rated on a 4-point Likert scale. These items are organised into seven domains of dysfunction: Physical and mental health, Locomotion, Body composition, Functionality, Activities of daily living, Leisure activities and Fears. In view of the pretest, the SarQoL is easy to complete, independently, in ∼10 min. The first version of the SarQoL, a specific quality of life questionnaire for sarcopenic subjects, has been developed and has been shown to be comprehensible by the target population. Investigations are now required to test the psychometric properties (internal consistency, test-retest reliability, divergent and convergent validity, discriminant validity, floor and ceiling effects) of this questionnaire. © The Author 2015.

    This review article aims to analyse whether patient feedback and questionnaires improve quality of care. It is recognized that patients cannot assess the medical competence of the clinician, yet patient experience provides an insight into the process of care through the patients’ eyes. Patient experience measures are more reliable for use to assess quality than patient satisfaction surveys. It is inappropriate to use patient satisfaction surveys as a basis for remuneration of dentists within the NHS. Patient Reported Outcome Measures (PROMs) have been a successful measure of patient experience in medicine and their introduction to dentistry needs to be considered. Clinical relevance: This article will enable clinicians to understand the importance of patient experience measures as a more reliable way of improving the quality of clinical care than patient satisfaction surveys.

    Obesity is a public health problem that disproportionately affects low-income populations. Moreover, participation in Supplemental Nutrition Assistance Program (SNAP) has been associated with obesity among low-income women. The goal of this study was to determine the impact of intrapersonal, home environment, community and social factors on diet quality and body mass index (BMI) of low-income women participating in SNAP. This study also aimed to examine the role of these factors in mediating the relationship between food insecurity and diet quality, and BMI. A total of 152 women receiving SNAP benefits were recruited from low-income neighborhood centers and housing communities, and administered a demographics questionnaire, the United States adult food security scale, food frequency questionnaire, and multi-dimensional home environment scale (MHES). They also were measured for height and weight to calculate BMI. The Dietary Guidelines Adherence Index 2015 was used to measure diet quality. Regression analyses were conducted to determine the MHES subscales that were significant predictors of diet quality and BMI. The Preacher and Hayes mediation model was used to evaluate the mediation of the relationship between food insecurity and diet quality, and BMI by the MHES. Emotional eating resistance and favorable social eating behaviors were positively associated with diet quality; whereas emotional eating resistance, lower availability of unhealthy food at home, neighborhood safety and favorable social eating behaviors were inversely associated with BMI in women participating in SNAP. The MHES significantly mediated the relationship between food insecurity and BMI. These results emphasize the importance of intrapersonal, home environment, community and social factors in mediating the relationship between food insecurity and BMI in low-income women.

    The aim of this study was to test the psychometric properties of a short questionnaire for work-related stress entitled Work Well index (WWi) and its interaction with different variables of self-reported health. An online survey was conducted in a sample of 1,218 employees (51% female) in four countries of an international insurance company. Internal consistency reliability, factorial validity, convergent validity and criterion validity of the 10-item WWi were analyzed. Good internal consistency reliability of the WWi was obtained (Cronbach's α coefficient = 0.85). Confirmatory factor analysis showed a satisfactory model fit of the data (AGFI = 0.92). The WWi was highly correlated to conceptually close constructs such as demand-control, effort-reward imbalance and workplace social capital (p < 0.001). Moreover, the 10-item WWi was significantly (p < 0.001) associated with elevated risk of self-rated health, absenteeism, presenteeism and depression (odds ratio 1.63, 1.36, 2.08, 2.95, respectively). We conclude that this short questionnaire is a reliable and valid instrument measuring psychosocial stress at work. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    Increasing numbers of programs are addressing the specific needs of homeless people with schizophrenia in terms of access to housing, healthcare, basic human rights and other domains. Although quality of life scales are being used to evaluate such programs, few instruments have been validated for people with schizophrenia and none for people with schizophrenia who experience major social problems such as homelessness. The aim of the present study was to validate the French version of the S-QoL a self-administered, subjective quality of life questionnaire specific to schizophrenia for people with schizophrenia who are homeless. In a two-step process, the S-QoL was first administered to two independent convenience samples of long-term homeless people with schizophrenia in Marseille, France. The objective of the first step was to analyse the psychometric properties of the S-QoL. The objective of the second step was to examine, through qualitative interviews with members of the population in question, the relevance and acceptability of the principle quality of life indicators used in the S-QoL instrument. Although the psychometric characteristics of the S-QoL were found to be globally satisfactory, from the point of view of the people being interviewed, acceptability was poor. Respondents frequently interrupted participation complaining that questionnaire items did not take into account the specific context of life on the streets. Less intrusive questions, more readily understandable vocabulary and greater relevance to subjects' living conditions are needed to improve the S-QoL questionnaire for this population. A modular questionnaire with context specific sections or specific quality of life instruments for socially excluded populations may well be the way forward.

    Public reporting of patient and graft outcomes in a national registry and close Centers for Medicare and Medicaid Services oversight has resulted in transplantation being a highly regulated surgical discipline. Despite this, transplantation surgery lacks comprehensive tracking and reporting of perioperative quality measures. Therefore, the aim of this study was to determine the association between a kidney transplantation centers' perioperative quality benchmarking and graft and patient outcomes. This was an analysis of 2011 aggregate data compiled from 2 national datasets that track outcomes from member hospitals and transplantation centers. The transplantation centers included in this study were composed of accredited US kidney transplantation centers that report data through the national registry and are associate members of the University HealthSystem Consortium. A total of 16,811 kidney transplantations were performed at 236 centers in the United States in 2011, of which 10,241 (61%) from 93 centers were included in the analysis. Of the 6 perioperative quality indicators, 3 benchmarked metrics were significantly associated with a kidney transplantation center's underperformance: mean ICU length of stay (C-statistic 0.731; p = 0.002), 30-day readmissions (C-statistic 0.697; p = 0.012) and in-hospital complications (C-statistic 0.785; p = 0.001). The composite quality index strongly correlated with inadequate center performance (C-statistic 0.854; p < 0.001, R(2) = 0.349). The centers in the lowest quartile of the quality index performed 2,400 kidney transplantations in 2011, which led to 2,640 more hospital days, 4,560 more ICU days, 120 more postoperative complications, and 144 more patients with 30-day readmissions, when compared with centers in the 3 higher-quality quartiles. An objective index of a transplantation center's quality of perioperative care is significantly associated with patient and graft survival. Copyright © 2014 American College of

    The way in which the quality of life related to health (HRQoL) is affected by the nutritional status of the patient is a subject of constant interest and permanent debate. The purpose of the present paper is to review those studies that relate HRQoL to nutritional status and examine the tools (questionnaires) that they use to investigate this relationship. A critical review of published studies was carried out via an investigation of the following databases: MEDLINE (via PubMed); EMBASE; The Cochrane Library; Cumulative Index to Nursing and Allied Health Literature (CINAHL); Institute for Scientific Information (ISI) Web of Science; Latin American and Caribbean Health Sciences Literature (LILACS); Spanish Health Sciences Bibliographic Index (IBECS). The search was carried out from the earliest date possible until July 2007.The medical subject heading terms used were 'quality of life', 'nutritional status' and 'questionnaires'. The articles had to contain at least one questionnaire that evaluated quality of life. Twenty-eight documents fulfilling the inclusion criteria were accepted, although none of them used a specific questionnaire to evaluate HRQoL related to nutritional status. However, some of them used a combination of generic questionnaires with the intention of evaluating the same. Only three studies selectively addressed the relationship between nutritional status and quality of life, this evaluation being performed not by means of specific questionnaires but by statistical analysis of data obtained via validated questionnaires.

    Background: Due to the lack of objective measures for assessing tinnitus, its clinical evaluation largely relies on the use of questionnaires and psychoacoustic tests. A global assessment of tinnitus burden would largely benefit from holistic approaches that not only incorporate measures of tinnitus but also take into account associated fears, emotional aspects (stress, anxiety, and depression), and quality of life. In Sweden, only a few instruments are available for assessing tinnitus, and the existing tools lack validation. Therefore, we translated a set of questionnaires into Swedish and evaluated their reliability and validity in a group of tinnitus subjects. Methods: We translated the English versions of the Tinnitus Functional Index (TFI), the Fear of Tinnitus Questionnaire (FTQ), the Tinnitus Catastrophizing Scale (TCS), the Perceived Stress Questionnaire (PSQ-30), and the Tinnitus Sample Case History Questionnaire (TSCHQ) into Swedish. These translations were delivered via the internet with the already existing Swedish versions of the Tinnitus Handicap Inventory (THI), the Hospital Anxiety and Depression Scale (HADS), the Hyperacusis Questionnaire (HQ), and the World Health Organization Quality of Life questionnaire (WHOQoL-BREF). Psychometric properties were evaluated by means of internal consistency [Cronbach's alpha (α)] and test-retest reliability across a 9-week interval [Intraclass Correlation Coefficient (ICC), Cohen's kappa] in order to establish construct as well as clinical validity using a sample of 260 subjects from a population-based cohort. Results: Internal consistency was acceptable for all questionnaires (α > 0.7) with the exception of the "social relationships" subscale of the WHOQoL-BREF. Test-retest reliability was generally acceptable (ICC > 0.70, Cohens kappa > 0.60) for the tinnitus-related questionnaires, except for the TFI "sense of control" subscale and 15 items of the TSCHQ.

    To evaluate the use of a short questionnaire to assess diet quality in older adults. Cross-sectional study. Hertfordshire, UK. 3217 community-dwelling older adults (59-73 years). Diet was assessed using an administered food frequency questionnaire (FFQ); two measures of diet quality were defined by calculating participants' 'prudent diet' scores, firstly from a principal component analysis of the data from the full FFQ (129 items) and, secondly, from a short version of the FFQ (including 24 indicator foods). Scores calculated from the full and short FFQ were compared with nutrient intake and blood concentrations of vitamin C and lipids. Prudent diet scores calculated from the full FFQ and short FFQ were highly correlated (0.912 in men, 0.904 in women). The pattern of associations between nutrient intake (full FFQ) and diet scores calculated using the short and full FFQs were very similar, both for men and women. Prudent diet scores calculated from the full and short FFQs also showed comparable patterns of association with blood measurements: in men and women, both scores were positively associated with plasma vitamin C concentration and serum HDL; in women, an inverse association with serum triglycerides was also observed. A short food-based questionnaire provides useful information about the diet quality of older adults. This simple tool does not require nutrient analysis, and has the potential to be of value to non-specialist researchers.

    Quality of life is an important outcome measurement in objectifying the current health status or therapy effects in patients with oropharyngeal dysphagia. In this study, the validity and reliability of the Dutch version of the Deglutition Handicap Index (DHI) and the MD Anderson Dysphagia Inventory (MDADI) have been determined for oncological patients with oropharyngeal dysphagia. At Maastricht University Medical Center, 76 consecutive patients were selected and asked to fill in three questionnaires on quality of life related to oropharyngeal dysphagia (the SWAL-QOL, the MDADI, and the DHI) as well as a simple one-item visual analog Dysphagia Severity Scale. None of the quality-of-life questionnaires showed any floor or ceiling effect. The test-retest reliability of the MDADI and the Dysphagia Severity Scale proved to be good. The test-retest reliability of the DHI could not be determined because of insufficient data, but the intraclass correlation coefficients were rather high. The internal consistency proved to be good. However, confirmatory factor analysis could not distinguish the underlying constructs as defined by the subscales per questionnaire. When assessing criterion validity, both the MDADI and the DHI showed satisfactory associations with the SWAL-QOL (reference or gold standard) after having removed the less relevant subscales of the SWAL-QOL. In conclusion, when assessing the validity and reliability of the Dutch version of the DHI or the MDADI, not all psychometric properties have been adequately met. In general, because of difficulties in the interpretation of study results when using questionnaires lacking sufficient psychometric quality, it is recommended that researchers strive to use questionnaires with the most optimal psychometric properties.

    Patient experience is an established indicator of quality of care. Validated tools that measure both experiences and priorities are lacking for chronic dialysis care, hampering identification of negative experiences that patients actually rate important. We developed two Consumer Quality (CQ) index questionnaires, one for in-centre haemodialysis (CHD) and the other for peritoneal dialysis and home haemodialysis (PHHD) care. The instruments were validated using exploratory factor analyses, reliability analysis of identified scales and assessing the association between reliable scales and global ratings. We investigated opportunities for improvement by combining suboptimal experience with patient priority. Sixteen dialysis centres participated in our study. The pilot CQ index for CHD care consisted of 71 questions. Based on data of 592 respondents, we identified 42 core experience items in 10 scales with Cronbach's α ranging from 0.38 to 0.88; five were reliable (α ≥ 0.70). The instrument identified information on centres' fire procedures as the aspect of care exhibiting the biggest opportunity for improvement. The pilot CQ index PHHD comprised 56 questions. The response of 248 patients yielded 31 core experience items in nine scales with Cronbach's α ranging between 0.53 and 0.85; six were reliable. Information on kidney transplantation during pre-dialysis showed most room for improvement. However, for both types of care, opportunities for improvement were mostly limited. The CQ index reliably and validly captures dialysis patient experience. Overall, most care aspects showed limited room for improvement, mainly because patients participating in our study rated their experience to be optimal. To evaluate items with high priority, but with which relatively few patients have experience, more qualitative instruments should be considered.

    Inflammatory bowel disease (IBD) has a significant impact on health-related quality of life (HRQOL). This study aims to investigate the variables which can be attributed to HRQOL in IBD patients. Seventy-one patients filled in IBD questionnaire (IBDQ-32), Pittsburgh sleep quality index questionnaire, and sociodemographic questionnaire. Disease activity was assessed by Crohn's disease activity index (CDAI) and ulcerative colitis activity index (UCAI). The correlations of sleep quality, sociodemographic variables, and disease characteristics with IBDQ were investigated. IBDQ-32 mean score was lower in patients who had hospitalization ( P = 0.01), poor sleep quality ( P < 0.001), anemia ( P = 0.03), more severe disease ( P = 0.01), and those who had not consumed folic acid ( P = 0.01) relative to their counterparts. A multivariate regression analysis identified the predictors of decreased HRQOL as not consuming folic acid ( P = 0.008), poor sleep quality ( P = 0.014), and disease severity ( P = 0.043). Impaired HRQOL was significantly associated with poor sleep quality, lack of folic acid consumption, and disease severity in IBD patients. Therefore, evaluation of folic acid level and efficacy of its supplementation in prospective studies is recommended. Treatment of sleep disturbance with pharmacological agents and nonpharmacological methods should be kept in mind as well.

Two-phase measure development study. 5144 patient care units in 857 United States hospitals participating in the National Database of Nursing Quality Indictors ® during the year 2013. The Pressure Ulcer and Fall Rate Quality Composite Index was developed in two phases. In Phase 1 the formula was generated using a utility function and generalized penalty analysis. Experts with experience in healthcare quality measurement provided the point of indicator equivalence. In Phase 2 initial validity evidence was gathered based on hypothesized relationships between the Pressure Ulcer and Fall Rate Quality Composite Index and other variables using two-level (unit, hospital) hierarchical linear mixed modeling. The Pressure Ulcer and Fall Rate Quality Composite Index=100-PUR-FR, where PUR is pressure ulcer rate and FR is total fall rate. Higher scores indicate better quality. Bland-Altman plots demonstrated agreement between pairs of experts and provided evidence for inter-rater reliability of the formula. The validation process demonstrated that higher registered nurse skill mix, higher percent of registered nurses with a baccalaureate in nursing or higher degree, higher percent of registered nurses with national specialty certification, and lower percent of hours supplied by agency staff were significantly associated with higher Pressure Ulcer and Fall Rate Quality Composite Index scores.

    Purpose  To translate into Portuguese, culturally adapt and validate the Uterine Fibroid Symptom - Quality of Life (UFS-QoL) questionnaire for Brazilian women with uterine leiomyoma. Methods  Initially, the UFS-QoL questionnaire was translated into Brazilian Portuguese in accordance with international standards, with subsequent cultural, structural, conceptual and semantic adaptations, so that patients were able to properly answer the questionnaire. Fifty patients with uterine leiomyoma and 19 patients without the disease, confirmed by abdominal pelvic examination and/or transvaginal ultrasound, were selected at the outpatient clinics of the Department of Gynecology of the Universidade Federal de São Paulo (Unifesp). The UFS-QoL questionnaire was administered to all women twice on the same day, with two different interviewers, with an interval of 15 minutes between interviews. After 15 days, the questionnaire was re-administered by the first interviewer. Reliability (internal consistency and test-retest), construct and discriminative validity were tested to ratify the questionnaire.

    The comprehensive water quality identification index method is able to assess the general water quality situation comprehensively and represent the water quality classification; water environment functional zone achieves pollution level and standard objectively and systematically. This paper selects 3 representative zones along deep-water channel of Guangzhou port and applies comprehensive water quality identification index method to calculate sea water quality monitoring data for different selected zones from year 2006 to 2014, in order to investigate the temporal variation of water quality along deep-water channel of Guangzhou port. The comprehensive water quality level from north to south presents an increased trend, and the water quality of the three zones in 2014 is much better than in 2006. This paper puts forward environmental protection measurements and suggestions for Pearl River Estuary, provides data support and theoretical basis for studied sea area pollution prevention and control.

    Rheumatoid arthritis (RA) afflicts approximately 1.5 million American adults and is a major cause of disability. As disease severity worsens, individuals with RA may experience functional decline that can impact dietary intake. The objective of this study is to assess the diet quality of individuals with RA using the Healthy Eating Index (HEI)-2010 and examine associations between diet quality and disease activity and functional status. This cross-sectional study assessed diet quality and disease activity and functional status in adults with RA. Participants completed seven-day weighed food records, which were scored using the HEI-2010. Participants had a fasting blood draw and completed the Multidimensional Health Assessment Questionnaire to determine disease activity and functional status. The mean age of individuals with RA ( N = 84) was 53 ± 14 years, and 86.9% were female. The mean HEI-2010 total score was 58.7 ± 15.9, with 7.1% of participants scoring "good", 58.3% "fair", and 34.5% "poor". Most participants did not adhere to recommended intakes of total fruit, total vegetables, whole grains, fatty acids, refined grains, sodium, and empty calories. An unadjusted multiple linear regression model found duration of morning stiffness and C-reactive protein concentration to be significant variables to inversely predict HEI-2010 total score. The diet quality of many individuals with RA needs improvement and may be related to functional disability associated with RA. Healthcare providers should encourage individuals with RA to meet dietary guidelines and maintain a healthy diet. Moreover, healthcare providers should be aware of the potential impacts of functional disability on diet quality in individuals with RA.

    Chronic non-specific lung disease (CNSLD) encompasses asthma as well as chronic obstructive pulmonary disease (COPD). Recently in health care, there has been increasing awareness in the functional, psychological and social aspects of the health of patients; their quality of life (QOL). Quality-of-life research addressing CNSLD patients has been rather underdeveloped for a long period of time. Recently, however, the importance of QOL is being increasingly recognized, and several research groups have started to study QOL in CNSLD patients in more detail. This paper describes the construction of a disease-specific QOL instrument for patients with mild to moderately severe CNSLD. Items relating to several domains of QOL were listed, and 171 CNSLD patients in general practice were asked how much of a problem each item had been (assessed on a seven-point Likert scale). After applying an item-selection procedure, a uni-dimensional QOL questionnaire was constructed consisting of 55 items divided into seven domain subscales: breathing problems, physical problems, emotions, situations triggering or enhancing breathing problems, general activities, daily and domestic activities, and social activities, relationships and sexuality. Reliability estimates of the domain subscales of the constructed questionnaire varied from 0.68 to 0.89, and was 0.92 for the QOL for Respiratory Illness Questionnaire (QOL-RIQ) total scale. A first impression of the construct validity of the questionnaire was gained by investigation of the relationship between the QOL domain subscales and several indicators of illness severity, as well as the relative contribution of illness severity variables, background characteristics and symptoms to QOL, using regression analysis. Further research to validate the questionnaire to a greater extent (construct validity, test-retest reliability and responsiveness to change) is currently taking place.

    Psoriasis severity varies by body region, with each affected region having a different impact on patient quality of life (QoL). The aim of this study was to assess the impact of changes in the Psoriasis Area and Severity Index (PASI) scores by body region on QoL in patients with psoriasis after treatment. A total of 100 patients with psoriasis were recruited to the study. All patients completed the generic EuroQol-5D instrument and two specific QoL measures, Dermatology Life Quality Index (DLQI) and Psoriasis Disability Index (PDI) at the beginning of the study, and 50 patients successfully completed the same questionnaires four weeks after the end of the treatment. Clinical severity was assessed using PASI total score and PASI body region (head, trunk, arms, and legs) scores. QoL improved after treatment, and PASI improvements on visible body regions (head, legs, and arms) showed significant correlation with the most sub-areas of the Visual Analog Scale (EQ VAS), DLQI, and PDI. Multiple linear regression analysis revealed that PASI improvement (particularly on the head), sex, age, and disease duration were predictors of QoL score changes for most domains of the three instruments. Improvement of psoriasis in visible body regions has an appreciable influence on QoL improvement, and may positively affect treatment success in patients with psoriasis.

    The Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) are questionnaires used to assess sleep quality and excessive daytime sleepiness in clinical and population-based studies. The present study aimed to evaluate the construct validity and factor structure of the PSQI and ESS questionnaires among young adults in four countries (Chile, Ethiopia, Peru and Thailand). A cross-sectional study was conducted among 8,481 undergraduate students. Students were invited to complete a self-administered questionnaire that collected information about lifestyle, demographic, and sleep characteristics. In each country, the construct validity and factorial structures of PSQI and ESS questionnaires were tested through exploratory and confirmatory factor analyses (EFA and CFA). The largest component-total correlation coefficient for sleep quality as assessed using PSQI was noted in Chile (r = 0.71) while the smallest component-total correlation coefficient was noted for sleep medication use in Peru (r = 0.28). The largest component-total correlation coefficient for excessive daytime sleepiness as assessed using ESS was found for item 1 (sitting/reading) in Chile (r = 0.65) while the lowest item-total correlation was observed for item 6 (sitting and talking to someone) in Thailand (r = 0.35). Using both EFA and CFA a two-factor model was found for PSQI questionnaire in Chile, Ethiopia and Thailand while a three-factor model was found for Peru. For the ESS questionnaire, we noted two factors for all four countries. Overall, we documented cross-cultural comparability of sleep quality and excessive daytime sleepiness measures using the PSQI and ESS questionnaires among Asian, South American and African young adults. Although both the PSQI and ESS were originally developed as single-factor questionnaires, the results of our EFA and CFA revealed the multi- dimensionality of the scales suggesting limited usefulness of the global PSQI and ESS scores

    A cross-cultural translation of the Vespid Allergy Quality of Life Questionnaire (VQLQ) to the Portuguese population (VQLQ-P) was performed, assessing its applicability in wasp and in non-beekeeper bee venom allergic patients. Additionally, we evaluated a Visual Analogue Scale (VAS) to estimate hymenoptera allergy interference with daily life. Methods. Cross-cultural translation was performed according to recommendations. The final VQLQ-P version, the Expectation of Outcome questionnaire (EoQ), EQ-5D and VAS were applied to wasp (n = 19) and non-beekeeper bee venom allergic patients (n = 30). Results. VQLQ-P significantly correlated with EoQ, (r = 0.76, p < 0.01), EQ-5D (usual activities and anxiety / depression dimensions) and VAS, with a good internal consistency (Cronbach α = 0.88) in wasp allergic individuals. VQLQ-P and EoQ correlation was also high (r = 0.67, p < 0.01) in bee allergy. Conclusion. The VQLQ-P is a valuable tool to evaluate quality of life impairment in Portuguese hymenoptera venom allergic individuals.

    The Biotic Index was developed in Western Countries in response to the need in water quality evaluation. This method analysis is based on the classification of aquatic macrobenthos as a bioindicator for clean and polluted water. The aim of this study is to compare the analysis of Cikapundung river using 6 different Biotic Indexes. BI Shannon-Weiner, Belgian Biological Index (BBI), Family Biotic Index (FBI), Biological Monitoring Working Party (BMWP), Biological Monitoring Working Party-Average Score Per Taxon (BMWP-ASPT), and A Scoring System for Macroinvertebrate in Australian River (A SIGNAL). Those analysis are compared with Physical Water Index (CPI) which is developed in Indonesia. The result shows that a decreasing water quality is detected upstream to downstream of Cikapundung River. However, based on the CPI analysis result, the BMWP-ASPT biotic index analysis is more comprehensive than other BI in explaining Cikapundung water quality.

    The aim of the study was to compare the efficacy of instruments to assess quality of life (QoL) in patients with moderate to severe persistent allergic rhinitis (PAR) vs intermittent allergic rhinitis (IAR). There were 106 patients with PAR and 99 with IAR and 50 healthy subjects in the control group. Questionnaire results were obtained using the Medical Outcomes Survey Short Form 36 (SF-36), a visual analog scale (VAS), and the rhinoconjunctivitis quality of life questionnaire (RQLQ) and were analyzed using correlational analysis. Correlations between the total scores and most domains of the 3 questionnaires were stronger in patients with PAR than in those with IAR, although the difference between groups was significant only for the RQLQ (P < .01). The QoL was worse in the PAR subgroup than in the IAR subgroup in the domains of social functioning in the SF-36 and for items of sleeping problems and activity limitations in the RQLQ. There were significant correlations between RQLQ and VAS-eye symptoms in the PAR subgroup but not in the IAR subgroup. The 3 questionnaires differentiated patients with AR from the healthy population, with significant but weak correlation with each other. The correlations were higher in patients with PAR than in those with IAR. The moderate to severe PAR has a greater effect on quality of life than IAR. Eye symptoms affected the QoL more in patients with PAR than in those with IAR. Copyright © 2011 Elsevier Inc. All rights reserved.

    This study aimed to develop a self-administered, multidimensional, poverty-related quality of life (PQoL) questionnaire for individuals seeking care in emergency departments (EDs): the PQoL-17. The development of the PQoL was undertaken in three steps: item generation, item reduction, and validation. The content of the PQoL was derived from 80 interviews with patients seeking care in EDs. Using item response and classical test theories, item reduction was performed in 3 EDs on 300 patients and validation was completed in 10 EDs on 619 patients. The PQoL contains 17 items describing seven dimensions (self-esteem/vitality, psychological well-being, relationships with family, relationships with friends, autonomy, physical well-being/access to care, and future perception). The seven-factor structure accounted for 75.1% of the total variance. This model showed a good fit (indices from the LISREL model: root mean square error of approximation, 0.055; comparative fit index, 0.97; general fit index, 0.96; standardized root mean square residual, 0.058). Each item achieved the 0.40 standard for item internal consistency, and Cronbach α coefficients were >0.70. Significant associations with socioeconomic and clinical indicators showed good discriminant and external validity. Infit statistics ranged from 0.82 to 1.16. The PQoL-17 presents satisfactory psychometric properties and can be completed quickly, thereby fulfilling the goal of brevity sought in EDs. Copyright © 2014 Elsevier Inc. All rights reserved.

    The aim of this study was to produce a drinking water assessment tool for operators of small distribution systems. A drinking water quality index (DWQI) was developed and applied to small systems based on the water quality index of the Canadian Council of Ministers of Environment. The drinking water quality index was adapted to specific needs by creating four drinking water quality scenarios. First, the temporal and spatial dimensions of drinking water quality variability were taken into account. The DWQI was designed to express global drinking water quality according to different monitoring frequencies. Daily, monthly, and seasonal assessment was also considered. With the data made available, it was possible to use the index as a spatial monitoring tool and express water quality in different points in the distribution system. Moreover, adjustments were made to prioritize the type of contaminant to monitor. For instance, monitoring contaminants with acute health effects led to a scenario based on daily measures, including easily accessible and affordable water quality parameters. On the other hand, contaminants with chronic effects, especially disinfection by-products, were considered in a seasonal monitoring scenario where disinfection by-product reference values were redefined according to their seasonal variability. A sensitivity analysis was also carried out to validate the index. Globally, the DWQI developed is adapted to the needs of small systems. In fact, expressing drinking water quality using the DWQI contributes to the identification of problematic periods and segments in the distribution system. Further work may include this index in the development of a customized decision-making tool for small-system operators and managers.

    The aim of this study was to validate the Acoustic Voice Quality Index 03.01 (AVQIv3) and the Acoustic Breathiness Index (ABI) in the Spanish language. Concatenated voice samples of continuous speech (cs) and sustained vowel (sv) from 136 subjects with dysphonia and 47 vocally healthy subjects were perceptually judged for overall voice quality and breathiness severity. First, to reach a higher level of ecological validity, the proportions of cs and sv were equalized regarding the time length of 3 seconds sv part and voiced cs part, respectively. Second, concurrent validity and diagnostic accuracy were verified. A moderate reliability of overall voice quality and breathiness severity from 5 experts was used. It was found that 33 syllables as standardization of the cs part, which represents 3 seconds of voiced cs, allows the equalization of both speech tasks. A strong correlation was revealed between AVQIv3 and overall voice quality and ABI and perceived breathiness severity. Additionally, the best diagnostic outcome was identified at a threshold of 2.28 and 3.40 for AVQIv3 and ABI, respectively. The AVQIv3 and ABI showed in the Spanish language valid and robust results to quantify abnormal voice qualities regarding overall voice quality and breathiness severity.

    The objective of this study is to validate an existing health-related quality of life questionnaire for patients with synkinesis in facial palsy for implementation in the Dutch language and culture. The Synkinesis Assessment Questionnaire was translated into the Dutch language using a forward-backward translation method. A pilot test with the translated questionnaire was performed in 10 patients with facial palsy and 10 normal subjects. Finally, cross-cultural adaption was accomplished at our outpatient clinic for facial palsy. Analyses for internal consistency, test-retest reliability, and construct validity were performed. Sixty-six patients completed the Dutch Synkinesis Assessment Questionnaire and the Dutch Facial Disability Index. Cronbach's α, representing internal consistency, was 0.80. Test-retest reliability was 0.53 (Spearman's correlation coefficient, P < 0.01). Correlations with the House-Brackmann score, Sunnybrook score, Facial Disability Index physical function, and social/well-being function were -0.29, 0.20, -0.29, and -0.32, respectively. Correlation with the Sunnybrook synkinesis subscore was 0.50 (Spearman's correlation coefficient). The Dutch Synkinesis Assessment Questionnaire shows good psychometric values and can be implemented in the management of Dutch-speaking patients with facial palsy and synkinesis in the Netherlands. Translation of the instrument into other languages may lead to widespread use, making evaluation, and comparison possible among different providers.

    Air quality indices based on the maximum of sub-indices of pollutants are easy to produce and help quantify the degree of air pollution. However, they discount the additive effects of multiple pollutants and are only sensitive to changes in highest sub-index. We propose a simple and concise method to construct an air quality index that takes into account additive effects of multiple pollutants and evaluate the extent to which this index predicts health effects. We obtained concentrations of four criteria pollutants: particulate matter with aerodynamic diameter ≤ 10μm (PM 10 ), sulphur dioxide (SO 2 ), nitrogen dioxide (NO 2 ) and ozone (O 3 ) and daily admissions to Hong Kong hospitals for cardiovascular and respiratory diseases for all ages and those 65 years or older for years 2001-2012. We derived sub-indices of the four criteria pollutants, calculated by normalizing pollutant concentrations to their respective short-term WHO Air Quality Guidelines (WHO AQG). We aggregated the sub-indices using the root-mean-power function with an optimal power to form an overall air quality index. The optimal power was determined by minimizing the sum of over- and under-estimated days. We then assessed associations between the pollution bands of the index and cardiovascular and respiratory admissions using a time-stratified case-crossover design adjusted for ambient temperature, relative humidity and influenza epidemics. Further, we conducted case-crossover analyses using the Hong Kong air quality data with the respective standards and classification of pollution bands of the China Air Quality Index (AQI), the United Kingdom Daily AQI (DAQI), and the United States Environmental Protection Agency (USEPA) AQI. The mean concentrations of PM 10 and SO 2 based on maximum 3-h mean exceeded the WHO AQG by 37% and 50%, respectively. We identified the combined condition of observed high-pollution days as either at least one pollutant > 1.5×WHO AQG or at least two pollutants > 1.0

    2016-08-01

    As telehealth applications emerge, the need for accurate and reliable biosignal quality indices has increased. One typical modality used in remote patient monitoring is the electrocardiogram (ECG), which is inherently susceptible to several different noise sources, including environmental (e.g., powerline interference), experimental (e.g., movement artifacts), and physiological (e.g., muscle and breathing artifacts). Accurate measurement of ECG quality can allow for automated decision support systems to make intelligent decisions about patient conditions. This is particularly true for in-home monitoring applications, where the patient is mobile and the ECG signal can be severely corrupted by movement artifacts. In this paper, we propose an innovative ECG quality index based on the so-called modulation spectral signal representation. The representation quantifies the rate of change of ECG spectral components, which are shown to be different from the rate of change of typical ECG noise sources. The proposed modulation spectral-based quality index, MS-QI, was tested on 1) synthetic ECG signals corrupted by varying levels of noise, 2) single-lead recorded data using the Hexoskin garment during three activity levels (sitting, walking, running), 3) 12-lead recorded data using conventional ECG machines (Computing in Cardiology 2011 dataset), and 4) two-lead ambulatory ECG recorded from arrhythmia patients (MIT-BIH Arrhythmia Database). Experimental results showed the proposed index outperforming two conventional benchmark quality measures, particularly in the scenarios involving recorded data in real-world environments.

    Melasma has been shown to have a significant emotional and psychologic effect on affected patients. Although this pigmentary disorder is thought to be more prevalent among Latinos, the effect of melasma on quality of life (QOL) in this population is unknown. The goals of this study were to translate and culturally adapt the previously validated Melasma QOL (MELASQOL) scale into Spanish language, to confirm the new scale's reliability and validity, and to administer the scale to characterize melasma's effect on the health-related QOL of Spanish language-speaking Latino patients. Cross-cultural adaptation of the original questionnaire was performed using previously established guidelines. After pretesting the questionnaire in a group of 30 patients, it was tested in a group of 112 patients recruited from a community outpatient clinic. A Spanish-language health-related QOL assessment battery was also administered for validation purposes. The degree of melasma was determined on clinical examination by the investigator using the Melasma Area and Severity Index. Cross-cultural adaptation of the questionnaire was successful in producing a working and understandable Spanish-language version of the MELASQOL. The Spanish-language MELASQOL scale was internally reliable and demonstrated construct and content validity. The Spanish-language MELASQOL scores of patients with little to no formal education were significantly higher than those with at least a seventh-grade education. Scores were proportional to the length of time a patient had lived with melasma and were higher in patients who had previously sought treatment. Spanish-language MELASQOL score and Melasma Area and Severity Index were shown to be moderately correlated, but no differences were seen according to patient age, marital status, employment, or coexisting medical or psychiatric conditions. Limitations are a lack of data regarding socioeconomic status and limitation to Mexican and Central American female patients

    To develop a questionnaire measuring sexual mental health of Tibetan university students. A draft questionnaire was developed with reference to the Sexual Civilization Survey for University Students of New Century and other published literature, and in consultation with experts. The questionnaire was tested in 230 students. Exploratory factor analyses with principal component and varimax orthogonal rotation were performed. Common factors with a > 1 eigenvalues and ≥ 3 loaded items (factor loading ≥ 0.4) were retained. Items with a < 0.4 factor loading, < 0.2 commonality, or falling into a common factor with < 3 items were excluded. The revised questionnaire was administered in another sample of 481 university students. Cronbach's α and split-half reliabilities were estimated. Confirmatory factor analyses were performed to test the construct validity of the questionnaire. Four rounds of exploratory factor analyses reduced the draft questionnaire items from 39 to 34 with a 7-factor structure. The questionnaire had a Cronbach's α of 0.920, 0.898, 0.812, 0.844, 0.787, 0.684, 0.703, and 0.608, and a Spearman-Brown coefficient of 0.763, 0.867, 0.742, 0838, 0.746, 0.822, 0.677, and 0.564 for the overall questionnaire and its 7 domains, respectively, suggesting good internal reliability. The structural equation of confirmatory factor analysis fitted well with the raw data: fit index χ²/df 3.736; root mean square residual (RMR) 0.081; root mean square error of approximation (RMSEA = 0.076; goodness of fit index (GFI) 0.805; adjusted goodness of fit index (AGFI) 0.770; normed fit index (NFI) = 0.774; relative fit index (RFI) 0.749; incremental fit index (IFI) 0.824; non-normed fit index (NNFI) = 0.803; comparative fit index (CFI) = 0.823; parsimony goodness of fit index (PGFI) = 0.684; parsimony normed fit index (PNFI) = 0.698; parsimony comparative fit index (PCFI) = 0.742, suggesting good construct validity of the questionnaire.

    The aim of this study was to assess the validity and interpretability of different preference-based questionnaires (generic 5-level EuroQol five-dimensional questionnaire [EQ-5D-5L], cancer-specific Quality of Life Questionnaire Preference-Based Measure, and European Organization of Randomized Controlled Trials 8 Dimension [EORTC-8D]) in patients with acute leukemia. Patients who participated in Hemato-Oncologie voor Volwassenen Nederland (HOVON - the Haemato Oncology Foundation for Adults in the Netherlands) clinical trials between 1999 and 2011 at a single hospital were invited to complete the questionnaires. Interpretability was evaluated by the frequency of incomplete data and highest and lowest possible scores. Content validity was evaluated by exploring the health-related quality-of-life domains included in the questionnaires. Construct validity was assessed using correlations with other quality-of-life scales (EQ-visual analogue scale score and global quality-of-life scale of the EORTC Quality of Life Questionnaire) and ability to distinguish between patients with different health statuses. Questionnaires were returned by 89% (111 of 125) of the patients. Six to seven respondents did not return full questionnaires. Perfect health on the EQ-5D-5L was reported by 32 respondents and many of them (N = 17) did report health problems on other questionnaires. All questionnaires were strongly correlated (range 0.61-0.78) with other quality-of-life scales and yielded substantially different utility values for patients with different health statuses. Nevertheless, the disease-specific preference-based questionnaires showed greater discriminatory power. Although the Quality of Life Questionnaire Preference-Based Measure and the EORTC-8D appear to have better validity, this study does not provide any strong evidence against the use of the EQ-5D-5L for measuring quality-of-life utilities in acute leukemia. However, our findings need to be confirmed in larger longitudinal

Questionnaire items were written on the basis of the 6 domains of everyday living affected by nystagmus that were elicited by previous semistructured interviews conducted with 21 people with nystagmus. After consultation with 8 nystagmus experts, 37 items were administered to 206 people with nystagmus. Factor analysis was used to identify latent factors among the items and identify items to propose new nystagmus QOL scales. Cronbach's alpha was used to assess the internal reliability of the new scales. To assess for discriminate and concurrent validity between the new nystagmus scales and an existing vision-related QOL tool, the Visual Function Questionnaire-25 (VFQ-25) was administered to 42 additional participants. Questionnaire response scores on nystagmus-specific QOL items. The factor analysis revealed the retention of 29 items to form a measure comprising 2 distinct subscales reflecting "personal and social" and "physical and environmental" functioning as relating to nystagmus-specific QOL. The Cronbach's alpha coefficients for the "personal and social" functioning scale and "physical and environmental" functioning were 0.95 and 0.93, respectively. Tests for validity of the measure, consistent with a priori predictions, when compared with the VFQ-25, revealed the "physical and environmental" subscale showed concurrent validity (0.88), whereas the "personal and social" subscale was demonstrated to have discriminative validity (0.81). We have developed a 29-item, nystagmus-specific QOL questionnaire (NYS-29) based on eudaimonic aspects of well-being with subscales that address not only physical functioning but also psycho-social issues. The NYS-29 is

    Background. The ReproQuestionnaire (ReproQ) measures the client’s experience with maternity care, following the WHO responsiveness model. In 2015, the ReproQ was appointed as national client experience questionnaire and will be added to the national list of indicators in maternity care. For using the ReproQ in quality improvement, the questionnaire should be able to identify best and worst practices. To achieve this, ReproQ should be reliable and able to identify relevant differences. Methods and Findings. We sent questionnaires to 17,867 women six weeks after labor (response 32%). Additionally, we invited 915 women for the retest (response 29%). Next we determined the test–retest reliability, the Minimally Important Difference (MID) and six known group comparisons, using two scorings methods: the percentage women with at least one negative experience and the mean score. The reliability for the percentage negative experience and mean score was both ‘good’ (Absolute agreement = 79%; intraclass correlation coefficient = 0.78). The MID was 11% for the percentage negative and 0.15 for the mean score. Application of the MIDs revealed relevant differences in women’s experience with regard to professional continuity, setting continuity and having travel time. Conclusions. The measurement characteristics of the ReproQ support its use in quality improvement cycle. Test–retest reliability was good, and the observed minimal important difference allows for discrimination of good and poor performers, also at the level of specific features of performance.

    Healthy dietary patterns have been linked positively with health and longevity. However, prospective studies in diverse populations in the United States addressing dietary patterns and mortality are limited. We assessed the ability of the following 4 diet-quality indexes [the Healthy Eating Index-2010 (HEI-2010), the Alternative HEI-2010 (AHEI-2010), the alternate Mediterranean diet score (aMED), and the Dietary Approaches to Stop Hypertension (DASH)] to predict the reduction in risk of mortality from all causes, cardiovascular disease (CVD), and cancer. White, African American, Native Hawaiian, Japanese American, and Latino adults (n = 215,782) from the Multiethnic Cohort completed a quantitative food-frequency questionnaire. Scores for each dietary index were computed and divided into quintiles for men and women. Mortality was documented over 13-18 y of follow-up. HRs and 95% CIs were computed by using adjusted Cox models. High HEI-2010, AHEI-2010, aMED, and DASH scores were all inversely associated with risk of mortality from all causes, CVD, and cancer in both men and women (P-trend < 0.0001 for all models). For men, the HEI-2010 was consistently associated with a reduction in risk of mortality for all causes (HR: 0.75; 95% CI: 0.71, 0.79), CVD (HR: 0.74; 95% CI: 0.69, 0.81), and cancer (HR: 0.76; 95% CI: 0.70, 0.83) when lowest and highest quintiles were compared. In women, the AHEI and aMED showed large reductions for all-cause mortality (HR: 0.78; 95% CI: 0.74, 0.82), the AHEI showed large reductions for CVD (HR: 0.76; 95% CI: 0.69, 0.83), and the aMED showed large reductions for cancer (HR: 0.84; 95% CI: 0.76, 0. 92). These results, in a US multiethnic population, suggest that consuming a dietary pattern that achieves a high diet-quality index score is associated with lower risk of mortality from all causes, CVD, and cancer in adult men and women. © 2015 American Society for Nutrition.

    Consumer Quality Index questionnaires are used to assess quality of care from patients' experiences. To provide insight into the agreement about quality of pharmaceutical care, measured both by a patient questionnaire and video observations. Pharmaceutical encounters in four pharmacies were video-recorded. Patients completed a questionnaire based upon the Consumer Quality Index Pharmaceutical Care after the encounter containing questions about patients' experiences regarding information provision, medication counseling, and pharmacy staff's communication style. An observation protocol was used to code the recorded encounters. Agreement between video observation and patients' experiences was calculated. In total, 109 encounters were included for analysis. For the domains "medication counseling" and "communication style", agreement between patients' experiences and observations was very high (>90%). Less agreement (45%) was found for "information provision", which was rated more positive by patients compared to the observations, especially for the topic, encouragement of patients' questioning behavior. A questionnaire is useful to assess the quality of medication counseling and pharmacy staff's communication style, but might be less suitable to evaluate information provision and pharmacy staff's encouragement of patients' questioning behavior. Although patients may believe that they have received all necessary information to use their new medicine, some information on specific instructions was not addressed during the encounter. When using questionnaires to get insight into information provision, observations of encounters are very informative to validate the patient questionnaires and make necessary adjustments.

    To determine whether night shift workers have a poorer diet quality and sleep quality when compared with day shift nurses. There is a dearth of research investigating the association between diet quality and sleep quality of day and night shift nurses. Data on nurses (n = 103) working either a day or night shift from two Midwestern hospitals were obtained from August 2015 to February 2016. The instruments used were the Diet History Questionnaire and the Pittsburg Sleep Quality Index. Independent samples t-tests were used to examine differences in diet and sleep quality by work shift schedule. There were no statistically significant differences between nurses working day or night shift and sleep quality (P = 0.0684), as well as diet quality (P = 0.6499). There was a significant difference between both body mass index (P = 0.0014) and exercise (P = 0.0020) with regard to diet quality. Body mass index and sleep quality were also significantly associated (P = 0.0032). Our study found no differences between day and night shift with regard to sleep and diet quality among nurses. Deliberate health initiatives and wellness programmes specifically targeting nurses are needed to increase knowledge about maintaining a healthy lifestyle while working as a nurse, whether it is day or night shift. © 2017 John Wiley & Sons Ltd.

  7. Validation of the self regulation questionnaire as a measure of health in quality of life research

    2009-01-01

    Objectives Several epidemiological studies address psychosomatic 'self regulation' as a measure of quality of life aspects. However, although widely used in studies with a focus on complementary cancer treatment, and recognized to be associated with better survival of cancer patients, it is unclear what the 'self regulation' questionnaire exactly measures. Design and setting In a sample of 444 individuals (27% healthy, 33% cancer, 40% other internal diseases), we performed reliability and exploratory factor analyses, and correlated the 16-item instrument with external measures such as the Hospital Anxiety and Depression Scale, the Herdecke Quality of Life questionnaire, and autonomic regulation questionnaire. Results The 16-item pool had a very good internal consistency (Cronbach's alpha = 0.948) and satisfying/good (rrt = 0.796) test-retest reliability after 3 months. Exploratory factor analysis indicated 2 sub-constructs: (1) Ability to change behaviour in order to reach goals, and (2) Achieve satisfaction and well-being. Both sub-scales correlated well with quality of life aspects, particularly with Initiative Power/Interest, Social Interactions, Mental Balance, and negatively with anxiety and depression. Conclusions The Self Regulation Questionnaire (SRQ) was found to be a valid and reliable tool which measures unique psychosomatic abilities. Self regulation deals with competence and autonomy and can be regarded as a problem solving capacity in terms of an active adaptation to stressful situations to restore wellbeing. The tool is an interesting option to be used particularly in complementary medicine research with a focus on behavioural modification. PMID:19541580

    Sexual dysfunction has been demonstrated to be related to a poor quality of life. These dysfunctions are especially prevalent among men. This cross-sectional study aimed to investigate the psychometric properties of the Persian translation of the Sexual Quality of Life–Male (SQOL-M), translated and adapted to measure sexual quality of life among Iranian men. Forward–backward procedures were applied in translating the original SQOL-M into Persian, and then the psychometric properties of the Persian translation of the SQOL-M were studied. A total of 181 participants (23-60 years old) were included in the study. Validity was assessed by construct validity using confirmatory factor analysis, convergent validity, and content validity. The international index of erectile function (IIEF) and the work ability index were used to study the convergent validity. Reliability was evaluated through internal consistency and test–retest reliability analyses. The results from confirmatory factor analysis confirmed a one-factor solution for the Persian version of the SQOL-M. Content validity of the translated measure was endorsed by 10 specialists. Pearson correlations indicated that work ability index score, dimensions of the IIEF, and the IIEF total score were positively correlated with the Persian version of the SQOL-M (p < .001). Reliability evaluation indicated a high internal consistency and test–retest reliability. The Cronbach’s alpha coefficient and intraclass correlation coefficients were .96 and .95, respectively. Results indicated that the Persian version of the SQOL-M has good to excellent psychometric properties and can be used to assess the sexual quality of life among Iranian men. PMID:26856758

    Nurse/patient relationship as a complex interrelation or as an interaction of the factor patient and factor nurse has been a subject of a number of studies during the past ten years. Nurse/patient communication is a special entity, usually observed within a framework of the wider nurse/patient relationship. In that regard, we wanted to develop a standardized questionnaire that could reliably measure the quality of communication between nurse and patient, and be used by nurses. The main goal of this study was to develop and evaluate construct validity of the Nurse Quality of Communication with Patient Questionnaire (NQCPQ), as well as to evaluate its reliability. The goal was also to establish a measure of inter-raters reliability, using two repeated measurements of results by items and scores of the NQCPQ, on the same observed units by two assessors. The starting NQCPQ that consists of 25 items, was filled in by two groups of nurses. Each nurse was questioned during morning and afternoon shifts, in order to evaluate their communication with hospitalized patients, using marks from 1 to 6. To evaluate construct validity, we used the analysis of main components, while reliability was assessed using intraclass correlation coefficient and Cronbach-alpha coefficient. To evaluate interraters reliability, we used Pearson correlation coefficient. Using a group of 118 patients, we explained 86% of the unknown, regarding the investigated phenomenon (communication nurse/patient), using one component by which we separated 6 items of the questionnaire. Inter-item correlation (alpha) in this component was 0.96. Pearson correlation coefficient was highly significant, value 0.7 by item, and correlation coefficient for scores at repeated measurements was 0.84. NQCPQ is 6-item instrument with high construct validity. It can be used to measure quality of nurse/patient communication in a simple, fast and reliable way. It could contribute to more adequate research and defining of this

    Good medicinal herbs, good drugs. Good evaluation method and indices are the prerequisite of good medicinal herbs. However, there exist numerous indices for quality evaluation and control in Chinese medicinal materials. However, most of these indices are non-interrelated each other, as well as having little relationship with efficiency and safety. The results of different evaluatior methods may not be consistent, even contradictory. Considering the complex material properties of Chinese medicinal materials, single method and index is difficult to objectively and comprehensively reflect the quality. Therefore, it is essential to explore the integrated evaluation methods. In this paper, oriented by the integrated evaluation strategies for traditional Chinese medicine quality, a new method called integrated quality index (IQI) by the integration of empirical evaluation, chemical evaluation, and biological evaluation was proposed. In addition, a study case of hypertoxic herb Aconitum carmichaelii Debx. was provided to explain this method in detail. The results suggested that in the view of specifications, the average weight of Jiangyou aconite was the greatest, followed by Weishan aconite, Butuo aconite, Hanzhong aconite, and Anxian aconite; from the point of chemical components, Jiangyou aconite had the characteristic with strong efficacy and weak toxicity, next was Hanzhong aconite, Butuo aconite, Weishan aconite, and Anxian aconite; taking toxicity price as the index, Hanzhong aconite and Jiangyou aconite have the lower toxicity, while Butuo aconite, Weishan aconite, and Anxian aconite have the relatively higher one. After the normalization and integration of evaluation results, we calculated the IQI value of Jiangyou aconite, Hanzhong aconite, Butuo aconite, Weishan aconite, and Anxian aconite were 0.842 +/- 0.091, 0.597 +/- 0.047, 0.442 +/- 0.033, 0.454 +/- 0.038, 0.170 +/- 0.021, respectively.

    Patient-relevant outcome measures are essential for high-quality clinical research, and quality-of-life (QoL) tools are the current standard. Currently, there is no validated children's acute cough-specific QoL questionnaire. The objective of this study was to develop and validate the Parent-proxy Children's Acute Cough-specific QoL Questionnaire (PAC-QoL). Using focus groups, a 48-item PAC-QoL questionnaire was developed and later reduced to 16 items by using the clinical impact method. Parents of children with a current acute cough (<2 weeks) at enrollment completed 2 validated cough score measures, the preliminary 48-item PAC-QoL, and 3 other questionnaires (the State Trait Anxiety Inventory [STAI], the Short-Form 8-item 24-hour recall Health Survey [SF-8], and the Depression, Anxiety, and Stress 21-item Scale [DASS21]). All measures were repeated on days 3 and 14. The median age of the 155 children enrolled was 2.3 years (interquartile range, 1.3-4.6). Median cough duration at enrollment was 3 days (interquartile range, 2-5). The reduced 16-item scale had high internal consistency (Cronbach α = 0.95). Evidence for repeatability and criterion validity was shown by significant correlations between the domains and total PAC-QoL scores and the SF-8 (r = -0.36 and -0.51), STAI (r = -0.27 and -0.39), and DASS21 (r = -0.32 and -0.41) scales on days 0 and 3, respectively. The final PAC-QoL questionnaire was sensitive to change over time, with changes significantly relating to changes in cough score measures (P < .001). The 16-item PAC-QoL is a reliable and valid outcome measure that assesses QoL related to childhood acute cough at a given time point and reflects changes in acute cough-specific QoL over time.

    The aim of this study was to examine measurement equivalence of the newly developed Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) across age, sex, and time in a representative sample of children with newly diagnosed epilepsy. Data come from 373 children enrolled in the Health-related Quality of Life in Children with Epilepsy Study (HERQULES), a multisite prospective cohort study. Measurement equivalence was examined using a multiple-group confirmatory factor analysis framework, whereby increasingly stringent parameter constraints are imposed on the model. Comparison groups were stratified based on age (4-7 years vs. 8-12 years), sex (male vs. female), and time (measurement of health-related quality of life at diagnosis vs. 24 months later). The QOLCE-55 demonstrated measurement equivalence at the level of strict invariance for each model tested--age: χ(2) (3,123) = 4,097.3, p < 0.001; Comparative Fit Index (CFI) = 0.968; Root Mean Square Error of Approximation (RMSEA) = 0.042 (0.038, 0.045); sex: χ(2) (3,124) = 4,188.3, p < 0.001; CFI = 0.964; RMSEA = 0.044 (0.040, 0.047); and time: χ(2) (3,121) = 5,185.0, p < 0.001; CFI = 0.965; RMSEA = 0.046 (0.043, 0.048). These findings suggest that items comprising the QOLCE-55 are perceived similarly among groups stratified by age, sex, and time and provide further evidence supporting the validity of the scale in children with epilepsy. Health professionals and researchers should be confident that group comparisons made using the QOLCE-55 are unbiased and that any group differences detected are meaningful; that is, not related to differences in the interpretation of items by informants. Future research replicating these findings is encouraged. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

    A metric of efficiency, a function of the ratio of quality to cost per patient, will allow the health care system to better measure the impact of specific reforms and compare the effectiveness of each. To develop and evaluate an efficiency index that estimates the performance of an ophthalmologist's practice as a function of cost, number of patients receiving care, and quality of care. Retrospective review of 36 ophthalmology subspecialty practices from October 2011 to September 2012 at a university-based eye institute. The efficiency index (E) was defined as a function of adjusted number of patients (N(a)), total practice adjusted costs (C(a)), and a preliminary measure of quality (Q). Constant b limits E between 0 and 1. Constant y modifies the influence of Q on E. Relative value units and geographic cost indices determined by the Centers for Medicare and Medicaid for 2012 were used to calculate adjusted costs. The efficiency index is expressed as the following: E = b(N(a)/C(a))Q(y). Independent, masked auditors reviewed 20 random patient medical records for each practice and filled out 3 questionnaires to obtain a process-based quality measure. The adjusted number of patients, adjusted costs, quality, and efficiency index were calculated for 36 ophthalmology subspecialties. The median adjusted number of patients was 5516 (interquartile range, 3450-11,863), the median adjusted cost was 1.34 (interquartile range, 0.99-1.96), the median quality was 0.89 (interquartile range, 0.79-0.91), and the median value of the efficiency index was 0.26 (interquartile range, 0.08-0.42). The described efficiency index is a metric that provides a broad overview of performance for a variety of ophthalmology specialties as estimated by resources used and a preliminary measure of quality of care provided. The results of the efficiency index could be used in future investigations to determine its sensitivity to detect the impact of interventions on a practice such as training

    A discussion and analysis of factors that contribute to nurses' happiness index can be useful in developing effective interventions to improve nurses' enthusiasm, sense of honor and pride and to improve the efficiency and quality of medical services. In this study, 206 registered nurses at the 2011 annual encounter for 12 Hanchuan hospitals completed a questionnaire survey that covered three aspects of the well-being index and thus served as a comprehensive well-being and general information tool. Based on their index score, the nurses' overall happiness level was moderate. The dimensions of the happiness index are listed in descending order of their contribution to the nurses' comprehensive happiness levels: health concerns, friendly relationships, self-worth, altruism, vitality, positive emotions, personality development, life satisfaction and negative emotions. Four variables (positive emotion, life satisfaction, negative emotions, and friendly relationships) jointly explained 47.80% of the total variance of the happiness index; positive emotions had the greatest impact on the happiness index. Appropriate nursing interventions can improve nurses' happiness index scores, thereby increasing nurses' motivation and promoting the development of their nursing practice.

    To assess the procedures of translation, cross-cultural adaptation, and measurement properties of breast cancer-specific quality-of-life questionnaires. Searches were conducted in the databases MEDLINE, EMBASE, CINAHL, and SciELO using the keywords: "Questionnaires," "Quality of life," and "Breast cancer." The studies were analyzed in terms of methodological quality according to the guidelines for the procedure of cross-cultural adaptation and the quality criteria for measurement properties of questionnaires. We found 24 eligible studies. Most of the articles assessed the translation and measurement properties of the instrument EORTC QLQ-BR23. Description about translation and cross-cultural adaptation was incomplete in 11 studies. Translation and back translation were the most tested phases, and synthesis of the translation was the most omitted phase in the articles. Information on assessing measurement properties was provided incompletely in 23 articles. Internal consistency was the most tested property in all of the eligible articles, but none of them provided information on agreement. Construct validity was adequately tested in only three studies that used the FACT-B and QLQ-BR23. Eight articles provided information on reliability; however, only four found positive classification. Responsiveness was tested in four articles, and ceiling and floor effects were tested in only three articles. None of the instruments showed fully adequate quality. There is limited evidence on cross-cultural adaptations and measurement properties; therefore, it is recommended that caution be exercised when using breast cancer-specific quality-of-life questionnaires that have been translated, adapted, and tested.

    The Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire is the most validated and the most specific tool for measuring the quality of life of patients with constipation. Over 120 million people live in countries whose official language is Persian. There is no reported Persian version of the PAC-QOL questionnaire yet. The aim of this study was to translate and culturally adapt the PAC-QOL questionnaire and to assess its reliability and validity among Persian patients with chronic constipation. Following the translation and cultural adaptation of the PAC-QOL questionnaire to Persian, 100 patients (mean±SD age=40.51±13.67) with constipation were recruited for validity measurement and 20 patients were re-examined for reliability. Content validity was assessed based on the opinions of an expert committee and the floor/ceiling effect. Construct validity was evaluated according to the hypothesis test. The SF-36 questionnaire was used for concurrent criterion validity, intra-class correlation coefficient for reliability, and Cronbach's alpha for internal consistency. The content validity of the PAC-QOL questionnaire was proven, and there was no floor/ceiling effect. Construct validity also was confirmed based on the hypothesis test. The overall Cronbach's alpha of the PAC-QOL questionnaire was 0.92 (range=0.72-0.92), and the overall intra-class correlation coefficient of the questionnaire was 0.88 (range=0.69-0.87). The correlation between the SF-36 and PAC-QOL questionnaires was moderate. The Persian version of the PAC-QOL questionnaire demonstrated good validity and reliability properties in chronic constipation. Accordingly, Persian researchers and clinicians can benefit from this questionnaire in further research and assessment of treatment outcomes.

    An illustrated version of the Dermatology Life Quality Index (DLQI) was developed in order to improve the ease with which this standard questionnaire is answered. To compare the illustrated version with the text-only version of the DLQI. The two versions were administered to 206 patients attending Dermatology outpatient clinics. The time taken to complete either the illustrated or the text-only version was noted in 52 additional patients. One hundred and ninety-one of 206 patients completed both questionnaires satisfactorily. Their mean DLQI scores were 6.4 (median 4.0, lower quartile 1.0, upper quartile 11.0) for the illustrated version and 6.3 (median 4.0, lower quartile 1.0, upper quartile 10.0) for the text-only version. For the 98 patients who answered the illustrated version first, the mean DLQI scores were 6.9 (median 4.0, lower quartile 1.9, upper quartile 11.9) for the illustrated version and 6.4 (median 4.0, lower quartile 1.8, upper quartile 11.0) for the text-only version. For the 93 patients who answered the text-only version first, the mean DLQI scores were 5.9 (median 4.0, lower quartile 1.7, upper quartile 10.2) for the illustrated version and 6.2 (median 5.0, lower quartile 0.5, upper quartile 9.5) for the text-only version. The median time taken to complete the text-only version was 124 s (mean +/- SD 126 +/- 65, n = 27) and 88 s (mean +/- SD 101 +/- 52, n = 25) for the illustrated version (P = 0.08). There was a very close correlation (r = 0.98) between the scores of the text-only and the illustrated versions; 82.2% of patients either scored the same or had a DLQI score difference of only 1. One hundred and seven (59.8%) patients preferred using the illustrated version and 66 (36.9%) preferred the text-only version. One hundred and four (57.5%) found the illustrated version easier to use. The illustrated version was superior to the text-only version in terms of patient preference and ease of use, but it was not possible to demonstrate exact

    Using paper questionnaires to measure quality of care from the perspective of the patient is a time consuming procedure resulting in very slow feedback. Response rates are low and patients who cannot read the local language are usually excluded. To investigate the applicability of an electronic questionnaire by evaluating the response rate. To study whether computer-based continuous monitoring could elucidate reasons for parents being less satisfied with care and treatment and to compare parent satisfaction with the results of a study performed in 2003. Parents were asked to assess the quality of care and treatment by answering questions on a touch-screen computer. The questions, which were translated into seven languages, corresponded to the indicators selected by the department for monitoring parents' satisfaction. The system was developed in cooperation with a software company. A total of 780 parents answered (69%). Of these, 2% parents answered in a foreign language. The main reasons for being less satisfied were perceived difficulties in getting in contact with the staff, having experienced unnecessary long waiting time and having the impression that the nurses did not have enough time. Significant improvements in satisfaction had occurred as compared to a study from 2003. By using electronic questionnaires, it was possible to focus on the small percentage of parents not satisfied, to identify reasons for being less satisfied and to respond immediately to the feedback from the parents. Electronic surveys produce a satisfactory response rates.

    Fibromyalgia syndrome (FMS) is a painful condition of unknown etiology, highly prevalent, and associated with other conditions, which causes great impact on daily life and quality of life. To assess, due to the multifactorial character of the FMS, the discriminating power of instruments used to identify good indicators of self-assessment and self-knowledge. This is a descriptive, exploratory, comparative, cross-sectional study with quantitative approach, and sample comprising a treatment group (T), diagnosed with FMS (n = 63) and a control group (C), undergoing interconsultation at the Pain Outpatient Clinic (n = 75). The following instruments were used: Fibromyalgia Impact Questionnaire (FIQ); visual analogue scale (VAS); McGill Pain Questionnaire; and the Post-Sleep Inventory (PSI). To evaluate the quality of life, Medical Outcomes Study 12-item Short-Form Health Survey (SF-12) was used. In the two groups, female gender predominated. The mean age of the sample was 42.3 ± 4.3 years, 45% were married, and the average schooling was 8 ± 3.5 years. The mean duration of pain was 3.2 years, and a mean time of two years were required for the clinical diagnosis of FMS in group T. Group T had higher levels of pain, anxiety, and depression, worse quality of sleep, less flexibility, and worse quality of life, although some of these symptoms were also present in group C. All instruments had good discriminating power (P < 0.05), especially FIQ, VAS and PSI, whose areas under the ROC curve were greater.

    The CAQI or Common Air Quality Index was proposed to facilitate the comparison of air quality in European cities in real-time. There are many air quality indices in use in the world. All are somewhat different in concept and presentation and comparing air quality presentations of cities on the internet was virtually impossible. The CAQI and the accompanying website www.airqualitynow.eu and app were proposed to overcome this problem in Europe. This paper describes the logic of making an index, in particular the CAQI and its update with a grid for PM2.5. To assure a smooth transition to the new calculation scheme we studied the behaviour of the index before and after the changes. We used 2006 Airbase data from 31 urban background and 27 street stations all across Europe (that were monitoring PM2.5 in 2006). The CAQI characterises a city by a roadside and urban background situation. It also insists on a minimum number of pollutants to be included in the calculation. Both were deemed necessary to improve the basis for comparing one city to another. A sensitivity analysis demonstrates the comparative behaviour of the street and urban background stations and presents the sensitivity of the CAQI outcome to the pollutants included in its calculation. © 2013.

    Despite its shortcomings, the Fibromyalgia Impact Questionnaire (FIQ) is widely used to assess clinical symptoms and measure therapeutic changes in patients with fibromyalgia (FM). Recently, the revised version of the FIQ (FIQR) was released. In this study, we validated the Korean version of the FIQR and evaluated whether the revised version is superior to the original version in reflecting the physical function and quality of life of these patients. Seventy-nine patients with FM were invited to complete a questionnaire that included the original FIQ, FIQR, Multidimensional Health Assessment Questionnaire (MDHAQ), Rheumatology Attitudes Index (RAI), and Medical Outcome Study Short-Form 36 (SF-36). The test-retest reliability was assessed in 55 patients after 1 week, and the Spearman coefficients were 0.604-0.825 and Cronbach's alpha was 0.948 (95% confidence interval 0.930-0.964). The FIQR was significantly correlated with the pain visual analogue scale (VAS), fatigue VAS, RAI, MDHAQ, and physical and mental component summary scores of the SF-36. The FIQR was more strongly associated with the MDHAQ and SF-36 scores than with the original FIQ. Our study showed that the FIQR is a reliable, valid instrument for assessing patients with FM and performs better in the prediction of physical function and health status than the original version. © 2015 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    Numerous supplements are used by sportspeople. They are not always appropriate for the individual or the sports activity and may do more harm than good. Vitamin and mineral supplements are unnecessary if the energy intake is sufficient to maintain body weight and derives from a diet with an adequate variety of foods. The study objectives were to evaluate the main nutrients used as supplements in sports and to propose a nutritional quality index (NQI) that enables sportspeople to optimize their use of supplements and detect and remedy possible nutritional deficits. A nutritional study was performed in 485 sportspeople recruited from Centros Andaluces de Medicina del Deporte, (CAMD). All completed socio-demographic, food frequency, and lifestyle questionnaires. The nutritional quality of their diet and need for supplementation were evaluated by scoring their dietary intake with and without supplementation, yielding two NQI scores (scales of 0-21 points) for each participant. A superior mean NQI score was obtained when the supplements taken by participants were not included (16. 28 (SD of 3.52)) than when they were included (15.47 (SD: 3.08)), attributable to an excessive intake of some nutrients through supplementation. These results indicate that sportspeople with a varied and balanced diet do not need supplements, which appear to offer no performance benefits and may pose a health risk.

    Sarcopenia, defined by a progressive and generalized loss of muscle mass and muscle function, is associated with many harmful clinical consequences. Several studies have reported the impact of sarcopenia on health-related quality of life (HRQoL) using generic quality of life (QoL) questionnaires. The results of these observational studies are quite heterogenous. Indeed, generic tools may not be able to detect subtle effects of sarcopenia on QoL. Recently, a sarcopenia-specific HRQoL questionnaire was developed and validated in a population of sarcopenic subjects to more accurately assess the impact of sarcopenia on QoL. Areas covered: The purpose of this review is to present evidence regarding the impact of sarcopenia on QoL and to introduce a new specific HRQoL questionnaire, the SarQoL®. Expert commentary: The self-administered SarQoL®, initially developed in French, comprises 55 items translated into 22 questions. The questionnaire has been shown to be understandable, valid, consistent, and reliable and can therefore be recommended for clinical and research purposes. The questionnaire is now available in 11 different languages with another 20 translations in progress. The instrument's sensitivity to change still needs to be assessed in future longitudinal studies.

    Health-related quality of life has been related to physical activity, sedentary behavior, and sleep among children from developed nations. These relationships have rarely been assessed in developing nations, nor have behaviors been considered in their true context, as mutually exclusive and exhaustive parts of the movement behavior composition. This study aimed to explore whether children's health-related quality of life is related to their movement behavior composition and if the relationship differs according to human development index. Children aged 9-11 years (n = 5855), from the 12-nation cross-sectional observational International Study of Childhood Obesity, Lifestyle and the Environment 2011-2013, self-reported their health-related quality of life (KIDSCREEN-10). Daily movement behaviors were from 24-h, 7-day accelerometry. Isometric log-ratio mixed-effect linear models were used to calculate estimates for difference in health-related quality of life for the reallocation of time between daily movement behaviors. Children from countries of higher human development index reported stronger positive relationships between health-related quality of life and moderate-to-vigorous physical activity, relative to the remaining behaviors (r = 0.75, p = 0.005) than those from lower human development index countries. In the very high human development index strata alone, health-related quality of life was significantly related to the movement behavior composition (p = 0.005), with moderate-to-vigorous physical activity (relative to remaining behaviors) being positively associated with health-related quality of life. The relationship between children's health-related quality of life and their movement behaviors is moderated by their country's human development index. This should be considered when 24-h movement behavior guidelines are developed for children around the world.

    A range of questionnaires have been used to assess health-related quality of life (HRQOL) in bronchiectasis. A systematic review was conducted to evaluate their psychometric properties and assess associations between HRQOL and clinical measures. Five electronic databases were searched. Studies eligible for inclusion were those that investigated the validity of HRQOL questionnaires and/or their association with other outcomes in adults with bronchiectasis. Patients with cystic fibrosis were excluded. The identified questionnaires were assessed for convergent, discriminant and cross-cultural translation validity; missing data, floor and ceiling effects, internal consistency, responsiveness and test-retest reliability. A meta-analysis was conducted to estimate the strength of associations between HRQOL and clinical measures. From 1918 studies identified, 43 studies were included in the systematic review, of which 38 were suitable for the meta-analysis. Nine HRQOL questionnaires were identified, with the most widely used being: St George's Respiratory Questionnaire, Leicester Cough Questionnaire, Quality of Life-Bronchiectasis and Short Form-36. HRQOL questionnaires had moderate to good internal consistency and good test-retest reliability. Only 8 of 18 studies that used translated HRQOL questionnaires reported or referred to the validity of the translated questionnaire. There was a stronger correlation (mean r (95% CI)) between HRQOL and subjective outcome measures, such as dyspnoea (0.55 (0.41 to 0.68)) and fatigue (0.42 (0.23 to 0.58)) compared with objective measures; exercise capacity (-0.41 (-0.54 to -0.24)), FEV1% predicted (-0.31 (-0.40 to -0.23)) and extent of bronchiectasis on CT scan (0.35 (0.03 to 0.61)); all p<0.001. This review supports most HRQOL questionnaires used in bronchiectasis have good psychometric properties. There was a weak to moderate association between HRQOL and objective outcome measures. This suggests that HRQOL questionnaires assess a

    Vertigo and dizziness, which are major symptoms of diseases affecting the vestibular system, drastically impair patients' health-related quality of life (QoL). Patient's perspectives are thus essential to symptom assessment. We sought to make a critical review of published questionnaires measuring vertigo or dizziness, and/or their impact on QoL. Twenty-nine articles reporting the validation or use in clinical trials of vertigo- or dizziness-specific questionnaires were identified over the 1991-2004 period, and reviewed using a methodological and a Patient-Reported Outcomes specific checklist. Questionnaires were classified into three categories according to content: QoL (or handicap), mixed (assessing both symptoms and QoL), and symptom questionnaires. Four QoL, three mixed questionnaires, two symptoms, and one Meniere's disease-specific questionnaire were identified. QoL questionnaire validation was usually not complete. The structural validity of the Dizziness Handicap Inventory is not established, although this questionnaire is considered to be the reference questionnaire in the QoL domain. Moreover, QoL questionnaires were not very specific to vertigo or dizziness. Similarly, the Vertigo Handicap Questionnaire appeared to have the most pertinent content, but its validation remains to be completed. Mixed questionnaires have the same imperfections. The Vertigo, Dizziness, Imbalance (VDI) Questionnaire had the best validation score from the checklist, but its responsiveness appears to be weak. Regarding symptom questionnaires, the European Evaluation of Vertigo questionnaire evaluated the five major symptoms of vestibular syndrome satisfactorily. The present literature review failed to find any relevant and validated questionnaire assessing the impact of vertigo or dizziness on QoL.

    Introduction Consumer Quality Index questionnaires are used to assess quality of care from patients’ experiences. Objective To provide insight into the agreement about quality of pharmaceutical care, measured both by a patient questionnaire and video observations. Methods Pharmaceutical encounters in four pharmacies were video-recorded. Patients completed a questionnaire based upon the Consumer Quality Index Pharmaceutical Care after the encounter containing questions about patients’ experiences regarding information provision, medication counseling, and pharmacy staff’s communication style. An observation protocol was used to code the recorded encounters. Agreement between video observation and patients’ experiences was calculated. Results In total, 109 encounters were included for analysis. For the domains “medication counseling” and “communication style”, agreement between patients’ experiences and observations was very high (>90%). Less agreement (45%) was found for “information provision”, which was rated more positive by patients compared to the observations, especially for the topic, encouragement of patients’ questioning behavior. Conclusion A questionnaire is useful to assess the quality of medication counseling and pharmacy staff’s communication style, but might be less suitable to evaluate information provision and pharmacy staff’s encouragement of patients’ questioning behavior. Although patients may believe that they have received all necessary information to use their new medicine, some information on specific instructions was not addressed during the encounter. When using questionnaires to get insight into information provision, observations of encounters are very informative to validate the patient questionnaires and make necessary adjustments.

    Consumption patterns are changing globally. As a result both researchers and policy makers require simple, easy to use measures of diet quality. The Healthy Eating Index (HEI) was developed as a single, summary measure of diet quality. The original HEI was a ten component index based on the US Dietary Guidelines and the Food Guide Pyramid. Research on the HEI indicates that the index correlates significantly with the RDA's for a range of nutrients and with an individual's self-rating of their diet. The revised HEI provides a more disaggregated version of the original index based on the 2005 Dietary Guidelines for Americans. Within each of the five major food groups, some foods are more nutrient dense than others. Nutrient Density algorithms have been developed to rate foods within food groups. The selection of the most nutrient dense foods within food groups lead to a dietary pattern with a higher HEI. The implications of using the HEI and nutrient density to develop interventions are discussed in this presentation.

    The postoperative quality of recovery-40 (QoR-40) is one of the most frequently used tools to assess the quality of recovery after surgery. The aim of the current study was to translate, culturally adapt, and validate the QoR-40 questionnaire in Arabic. A systematic translation process was used to translate the original English QoR-40 into Arabic. After the pilot study, the translated version was validated among patients who underwent different types of surgeries. The reliability (using internal consistency) and validity of our translated Arabic version was examined. To investigate the responsiveness of the translated QoR-40, the questionnaire was administered five times among the same group of patients (once before surgery as baseline measure, and four times after surgery, up to 1 week after surgery). A total of 182 participants (7 men, 175 women) were included in the study. The QoR-40 total scale and all subscales showed excellent internal consistencies over time, with the exception of the QoR-40 pain subscale at postoperative day 1. The QoR-40 total and subscale scores were inversely associated with patients' self-report pain scores but positively correlated with patients' self-report recovery scores. Patients' QoR-40 total, comfort, emotions, and physical subscale scores increased over time after surgery, indicating a general trend of recovery over time. Patients' scores in the QoR-40 pain and support subscales remained stable over time, suggesting no substantial changes were reported in these two domains. Quality of recovery was also found to be related to patients' ages, American Society of Anesthesiologists Physical Status, and the extent of surgery (major vs. minor). Most patients found the Arabic QoR-40 questions to be clear and easy to understand and thought the questionnaire items covered all their problem areas regarding their quality of recovery. Our translated version of QoR-40 was reliable and valid for use among Arabic-speaking patients. In addition

    Proper assessment of air quality status in an atmosphere based on limited observations is an essential task for meeting the goals of environmental management. A number of classification methods are available for estimating the changing status of air quality. However, a discrepancy frequently arises from the quality criteria of air employed and vagueness or fuzziness embedded in the decision making output values. Owing to inherent imprecision, difficulties always exist in some conventional methodologies like air quality index when describing integrated air quality conditions with respect to various pollutants parameters and time of exposure. In recent years, the fuzzy logic-based methods have demonstrated to be appropriated to address uncertainty and subjectivity in environmental issues. In the present study, a methodology based on fuzzy inference systems (FIS) to assess air quality is proposed. This paper presents a comparative study to assess status of air quality using fuzzy logic technique and that of conventional technique. The findings clearly indicate that the FIS may successfully harmonize inherent discrepancies and interpret complex conditions.

    The Restinga Forest is a set of plant communities in mosaic, determined by the characteristics of their substrates as a result of depositional processes and ages. In this complex mosaic are the physiognomies of restinga forests of high-stage regeneration (high restinga) and middle stage of regeneration (low restinga), each with its plant characteristics that differentiate them. Located on the coastal plains of the Brazilian coast, suffering internal influences both the continental slopes, as well as from the sea. Its soils come from the Quaternary and are subject to constant deposition of sediments. The climate in the coastal type is tropical (Köppen). This work was conducted in four locations: (1) Anchieta Island, Ubatuba, (2) Juréia-Itatins Ecological Station, Iguape, (3) Vila das Pedrinhas, Comprida Island; and (4) Cardoso Island, Cananeia. The soil samples were collect at a depths of 0 to 5, 0-10, 0-20, 20-40 and 40 to 60cm for the chemical and physical analysis. Were studied the additive and pondering additive models to evaluate soil quality. It was concluded: a) the comparative additive model produces quantitative results and the pondering additive model quantitative results; b) as the pondering additive model, the values of Soil Quality Index (SQI) for soils under forest of restinga are low and realistic, demonstrating the small plant biomass production potential of these soils, as well as their low resilience; c) the values of SQI similar to areas with and without restinga forest give quantitative demonstration of the restinga be considered as soil phase; d) restinga forest, probably, is maintained solely by the cycling of nutrients in a closed nutrient cycling; e) for the determination of IQS for soils under restinga vegetation the use of routine chemical analysis is adequate. Keywords: Model, restinga forest, Soil Quality Index (SQI).

    In the past few decades, Indoor Air Pollution (IAP) has become a primary concern to the point. It is increasingly believed to be of equal or greater importance to human health compared to ambient air. However, due to the lack of comprehensive indices for the integrated assessment of indoor air quality (IAQ), we aimed to develop a novel, Fuzzy-Based Indoor Air Quality Index (FIAQI) to bridge the existing gap in this area. We based our index on fuzzy logic, which enables us to overcome the limitations of traditional methods applied to develop environmental quality indices. Fifteen parameters, including the criteria air pollutants, volatile organic compounds, and bioaerosols were included in the FIAQI due mainly to their significant health effects. Weighting factors were assigned to the parameters based on the medical evidence available in the literature on their health effects. The final FIAQI consisted of 108 rules. In order to demonstrate the performance of the index, data were intentionally generated to cover a variety of quality levels. In addition, a sensitivity analysis was conducted to assess the validity of the index. The FIAQI tends to be a comprehensive tool to classify IAQ and produce accurate results. It seems useful and reliable to be considered by authorities to assess IAQ environments.

    Background Few quality of life (QOL) assessment tools are available for children with specific chronic conditions, and none have been designed specifically for children with hearing loss (HL). A validated hearing-related QOL questionnaire could help clinicians determine whether an intervention is beneficial and whether one intervention is better than another. Purpose To examine QOL in children with HL and assess the validity, reliability, and factor structure of a new measure, the Hearing Environments and Reflection on Quality of Life (HEAR-QL) questionnaire. Research Design A descriptive and correlational study of a convenience sample of children. Study Sample Participants included 35 children with unilateral HL, 45 with bilateral HL, and 35 siblings with normal hearing. Data Collection and Analysis Children 7-12 years old were recruited by mail from a tertiary-care pediatric otolaryngology practice and the local county's Special School District. With parent consent, children completed the validated Pediatric Quality of Life Inventory™ (PedsQL™) 4.0 and a 35-item HEAR-QL questionnaire. The factor structure of the HEAR-QL was determined through principal components analysis (PCA), and mean scores were computed for each subscale and the total HEAR-QL. Three weeks following return of the initial questionnaires, a second HEAR-QL questionnaire was sent to participants to assess test-retest reliability. Both PedsQL and HEAR-QL scores were compared between children with and without HL, between children with unilateral and bilateral HL, and between children who used and did not use a hearing device using analysis of variance. Sensitivity and specificity were calculated for both the HEAR-QL and PedsQL. A multivariable, hierarchical linear regression analysis was conducted with independent variables associated with HEAR-QL in unadjusted tests. Results Using exploratory PCA, the 35-item HEAR-QL was reduced to 26 items (Cronbach's α=0.97; sensitivity 91% and specificity

    To determine the minimal clinically important difference (MCID) of the Dermatology Life Quality Index (DLQI) and its responsiveness to change in inflammatory skin diseases. A longitudinal study: at stage 1, patients completed the DLQI and a disease severity global question; at stage 2, a global rating of change in quality of life (QoL; Global Rating of Change Questionnaire, GRCQ) was added and used as an anchor to measure the MCID of the DLQI. 192 patients completed stage 1 and 107 completed stage 2. The mean DLQI score at stage 1 was 9.8 and 7.4 at stage 2 with a mean change of 2.4 (p < 0.0001). 31 patients experienced a 'small change' in their QoL (±3 and ±2) on the GRCQ. The mean corresponding change in DLQI scores was 3.3, which is regarded as the approximate MCID. Previous estimates of the MCID of the DLQI have varied from 3 to 5. Although this study demonstrated a MCID of 3.3, we recommend that the MCID in inflammatory skin diseases should be 4. © 2015 S. Karger AG, Basel.

    Obesity not only increases risk for morbidity/mortality, but also impacts the quality of life of obese individuals. In the United States, black women have the highest prevalence of obesity of any other group with approximately 80% of black women over age 20 having a body mass index (BMI) ≥25 kg/m2. We aimed to examine the association between BMI and quality of life in this high risk population compared to this association in white women, using the Impact of Weight on Quality of Life (IWQOL)-Lite questionnaire. Data from 172 black women (mean BMI= 35.7; age=40.5) and 171 white women (mean BMI= 35.5; age=40.4) were collected between 2000 and 2010 analyzed in 2010. The mean IWQOL-Lite total score was 81.6 for black women compared to 66.9 for white women, a statistically significant difference. Hierarchical linear regression models revealed a significant BMI-by-race interaction indicating that the relationship between BMI and IWQOL-Lite score was moderated by race. Our findings suggest notable differences in weight-related quality of life in black and white women. At similar BMIs, black women consistently reported better quality of life than white women on all IWQOL-Lite subscales. The greatest difference in IWQOL-Lite scores between black and white women was seen in the self-esteem subscale. Additional research is needed to understand how to incorporate the weight perspectives of black women into weight management messages and interventions. PMID:28286583

    To identify a simplified factor structure for the PROQOL-human immunodeficiency virus (HIV) questionnaire to improve the measurement of the health-related quality of life (HRQL) of HIV-positive patients in clinical care and research settings. HRQL data were collected using the eight-dimension PROQOL-HIV questionnaire from 2,537 patients (VESPA2 study). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) validated a simpler four-factor structure and assessed measurement invariance (MI). Multigroup analysis assessed the effect of sex, age, and antiretroviral therapy (ART) on the resulting factor scores. Correlations with symptom and Short Form (SF)-12 self-reports assessed convergent validity. Item analysis, EFA, and CFAs confirmed the validity [comparative fit index (CFI), 0.948; root mean square error of approximation, 0.064] and reliability (α's ≥ 0.8) of four dimensions: physical health and symptoms, health concerns and mental distress, social and intimate relationships, and treatment-related impact. Strong MI was demonstrated across sex and age (decrease in CFI <0.01). A multiple-cause multiple-indicator model indicated that HRQL correlated as expected with sex, age, and the ART status. Correlations of HRQL, symptom reports, and SF-12 scores evidenced convergent validity criterion. The simplified factor structure and scoring scheme for PROQOL-HIV will allow clinicians to monitor with greater reliability the HRQL of patients in clinical care and research settings.

    Eating behaviours play a crucial role in the development of obesity. To conduct a psychometric analysis of the Three-Factor Eating Questionnaire-R21 and to investigate the correlates of obesogenic eating behaviours among males. Participants of the cross-sectional questionnaire-based study were male university students (n = 239, mean of age: 20.3 years, SD = 2.78 years). self-reported body weight and body height, Three-Factor Eating Questionnaire-R21, Trait Anxiety Scale of the State-Trait Anxiety Inventory. Results of confirmatory factor analysis supported the theoretical model of the Three-Factor Eating Questionnaire-R21 (χ 2 (186) = 366.1, p<0.001, CFI = 0.959, TLI = 0.954, RMSEA = 0.064). Internal consistency of the scales was adequate (Cronbach's α: 0.79-0.88). Body Mass Index and trait anxiety showed significant, positive associations with eating behaviours, such as uncontrolled eating, cognitive restraint, and emotional eating. Results support the construct validity and reliability of the Three-Factor Eating Questionnaire-R21 among males and highlight the importance of taking psychological factors into account in the prevention of obesity.

    The aim of this study was the translation, cross-cultural adaptation, and validation of the Sleep Apnea Quality of Life Index (SAQLI) in Persian-speaking patients with obstructive sleep apnea (OSA). Ninety-six patients with OSA completed a series of questionnaires including SAQLI, Epworth Sleepiness Scale (ESS),10-item Functional Outcomes of Sleep Questionnaire (FOSQ-10), and Medical Outcome Survey Short form 12 (SF-12) for assessment of reliability, validity, and responsiveness of Persian version of SAQLI. The Persian version of SAQLI had a very good internal consistency and also demonstrated good test-retest reliability. Concurrent validity was confirmed by significant correlations with ESS, FOSQ-10 and SF-12 subscale scores. Comparison of SAQLI scores in groups of patients categorized by ESS showed the high discriminative power of this instrument. However, there was no significant difference in the SAQLI scores of patients with mild, moderate, and severe sleep apnea. The results of sensitivity to change verified that the SAQLI was able to detect changes after continuous positive airway pressure (CPAP) treatment. The findings of this study indicate that the Persian version of SAQLI is a reliable, valid, and responsive measure for evaluation of quality of life in patients with OSA.

    Overactive bladder syndrome is a common syndrome in the world in both men and women. Correct diagnosis and accurate measurement of symptoms severity and also quality of life of patients is necessary to ensure proper treatment and to facilitate sound relationships among patients, researchers and doctors. The International Consultation on Incontinence Questionnaire in Over Active Bladder (ICIQ-OAB) questionnaire is a concise and strong tool to evaluate the symptoms of OAB and their effects on patients' quality of life and treatment results. The objective of this study was to translate and validate a simple and strong tool that could be used in clinics and research. First, the original British English questionnaire was translated into Persian by two bilingual and originally Persian-speaking translators. Then the Persian version was back translated to English and a native English speaker studied and compared the questionnaire with the original version. At the end, the translated and corrected Persian version was finalized by a research team. Content validity of the items and ensuring that the questions could convey the main concept to readers was assessed through Modified Content Validity Index (MCVI). Reliability was calculated by Cronbach's α coefficient. Internal Consistency of the questionnaire with the calculation of Kendall correlation coefficient were evaluated by performing test-retest in 50 participants. The modified content validity index was > 0.78 for all of the questions. Cronbach's α coefficient was calculated 0.76 for all of the participants. Kendall correlation coefficient was calculated for test-re-test assessment 0.66. Both of which indicates the reliability of this questionnaire. Persian version of ICIQ-OAB questionnaire is a simple and strong tool for research, treatment and screening purposes. © 2014 Wiley Publishing Asia Pty Ltd.

    The CareGiver Oncology Quality of Life (CarGOQoL) questionnaire, a 29-item, multidimensional, self-administered questionnaire, was validated using a large French sample. We reported the linguistic validation process and the metric validity of the English version of CarGOQoL in the United- States. The translation process consisted of 3 consecutive steps: forward-backward translation, acceptability testing, and cognitive interviews. The psychometric testing was applied to caregivers of consecutive patients with representative cancers who were recruited from the Regional Cancer Center in northwestern Pennsylvania. All individuals completed the CarGOQoL at baseline, day- 30, and day- 90. Internal consistency, reliability, external validity, reproducibility, and sensitivity to change were tested. The translated version was validated on a total of 87 American cancer caregivers. The dimensions of the CarGOQoL generally demonstrated a high internal consistency (Cronbach's alpha > 0.70 for all but four domain scores). External validity testing revealed that the CarGOQoL index score correlated significantly with all SF-36 dimension scores except the physical composite score (Pearson's correlation: 0.28-0.70). Reproducibility was satisfactory at day- 30 (intraclass correlation coefficient: 0.46-0.94) and day- 90 (0.43-0.92). Four specific dimensions of CarGOQoL showed responsiveness: the Psychological well-being, the Relationships with health care system, the Social support and the Finances. The American version of the CarGOQoL constitutes a useful instrument to measure QoL in caregivers of cancer patients in the United- States.

    Optical quality glass having a selected refractive index is produced by a two stage drying process. A gel is produced using sol-gel chemistry techniques and first dried by controlled evaporation until the gel volume reaches a pre-selected value. This pre-selected volume determines the density and refractive index of the finally dried gel. The gel is refilled with solvent in a saturated vapor environment, and then dried again by supercritical extraction of the solvent to form a glass. The glass has a refractive index less than the full density of glass, and the range of achievable refractive indices depends on the composition of the glass. Glasses having different refractive indices chosen from an uninterrupted range of values can be produced from a single precursor solution.

    Vitiligo is a multi-factorial pigmentary skin disorder. Recently, the importance of emotional and psychological issues is proposed in incidence, progression, relapse and remission of vitiligo. There are limited studies conducted in developing countries, which assess life quality of patients with vitiligo. The aim of this study was the application and evaluation of a disease-specific quality of life index in Iranian patients, for the first time. This cross-sectional biphasic study was conducted on 25 patients as a pilot and another 173 patients as the main study group, in Razi Hospital, Tehran, Iran, 2013-2014. Persian version of Vitiligo Quality of Life index (VitiQoL) was developed with backward-forward method. Based on the pilot study, the validity and reliability were assessed. The Vitiligo Area and Score Index (VASI), VitiQoL, and their relationship, demographic and clinical characteristic of patients were measured. The Mean and standard deviation of the VitiQoL score was 30.5 ± 14.5 (range 0-60 in Persian version). There was a significant relationship between VASI score and VitiQoL (p = 0.015, r = 0.187). Confirmatory factor analysis revealed three important factors within VitiQoL: participation limitation, stigma, and behavior. In subscale analysis based on behavior factor, female patients had poorer quality of life (p = 0.02). Concomitant psychiatric problems, e.g. anxiety and depression, were not associated with QOL; however, they were near to being meaningful (p = 0.06, r = 0.14). VitiQoL is a valid index in estimating life quality of vitiligo patients and has proper relation to disease severity. Focusing on patient's life quality is an important entity in the management of vitiligo patients; relevant supportive group-based consultations and therapies are also important arms when approaching vitiligo.

    Due to the increased prevalence of obesity in many countries, the number of bariatric surgeries is increasing. They are considered the most effective treatment for obesity. In the postoperative there may be difficulties with the quality of alimentation, tolerance to various types of food, as well as vomiting and regurgitation. Few surveys are available to assess these difficulties in the postoperative. To perform a systematic literature review about food tolerance in patients undergoing bariatric surgery using the questionnaire "Quality of Alimentation", and compare the results between different techniques. A descriptive-exploratory study where the portals Medline and Scielo were used. The following headings were used in english, spanish and portuguese: quality of alimentation, bariatric surgery and food tolerance. A total of 88 references were found, 14 used the questionnaire "Quality of Alimentation" and were selected. In total, 2745 patients were interviewed of which 371 underwent to gastric banding, 1006 to sleeve gastrectomy, 1113 to Roux-en-Y gastric bypass, 14 to biliopancreatic diversion associated with duodenal switch, 83 were non-operated obese, and 158 non-obese patients. The questionnaire showed good acceptability. The biliopancreatic diversion with duodenal switch had the best food tolerance in the postoperative when compared to other techniques, but it was evaluated in a single article with a small sample. The longer the time after the operation, the better is the food tolerance. Comparing the sleeve gastrectomy and the Roux-en-Y gastric bypass, there are still controversial results in the literature. The gastric banding had the worst score of food tolerance among all the techniques evaluated. The questionnaire is easy and fast to assess the food tolerance in patients after bariatric surgery. Biliopancreatic diversion with duodenal switch had the best food tolerance in the postoperative when compared to sleeve gastrectomy and the Roux-en-Y gastric

    Little is known about the effects of noninvasive ventilation (NIV) on sleep quality in amyotrophic lateral sclerosis (ALS). We aim to evaluate the long-term effects of NIV on sleep quality and quality of life in patients with ALS. In this prospective observational study, 13 ALS patients were followed for one year after initiating NIV. We evaluated sleep quality, quality of life and functional status with several questionnaires: Epworth sleepiness Scale (ESS), Pittsburg sleep quality index (PSQI), Short Form 36 Health Questionnaire (SF-36), McGill Quality of Life questionnaire (McGillQoL) and revised Amyotrophic Lateral Sclerosis Functional Rating Scale scores (ALSFRS-R). Median and interquartile range (IQR) at the start of NIV was 59 (53-65) years. The ALSFRS-R at start was 30 (24-37) (median, IQR), with three patients having severe bulbar impairment (ALSFRS-R-bulbar ≤ 9). The P a CO 2 at start of NIV treatment was 48 (43-52) mmHg (median, IQR). During the one-year follow-up period, a significant decrease in the ALSFRS-R was observed. The impact of NIV in a short term (1 month) revealed a statistically significant decrease in ESS, decrease in total PSQI and of four PSQI subscales and improvement of almost all subscales of the McGill questionnaire. Long-term analyses (9 months to 1 year) revealed that amelioration in ESS and total PSQI was sustained. We conclude that accurately titrated NIV in ALS patients can stabilize sleep quality and quality of life for at least one year, despite significant disease progression.

    The development and validation of questionnaires for evaluating quality of life (QoL) has become an important area of research. However, there is a proliferation of non-validated measuring instruments in the health setting that do not contribute to advances in scientific knowledge. To present, through the analysis of available validated questionnaires, a checklist of the practical aspects of how to carry out the cross-cultural adaptation of QoL questionnaires (generic, or disease-specific) so that no step is overlooked in the evaluation process, and thus help prevent the elaboration of insufficient or incomplete validations. We have consulted basic textbooks and Pubmed databases using the following keywords quality of life, questionnaires, and gastroenterology, confined to «validation studies» in English, Spanish, and Portuguese, and with no time limit, for the purpose of analyzing the translation and validation of the questionnaires available through the Mapi Institute and PROQOLID websites. A checklist is presented to aid in the planning and carrying out of the cross-cultural adaptation of QoL questionnaires, in conjunction with a glossary of key terms in the area of knowledge. The acronym DSTAC was used, which refers to each of the 5 stages involved in the recommended procedure. In addition, we provide a table of the QoL instruments that have been validated into Spanish. This article provides information on how to adapt QoL questionnaires from a cross-cultural perspective, as well as to minimize common errors.

    The Walking Impairment Questionnaire (WIQ) is a short, easy to complete, disease-specific questionnaire to assess intermittent claudication. A Spanish version of the WIQ for Hispanic Americans has recently been validated in Texas, but it needs to be validated for European Spanish people. After translation and cultural adaptation of the WIQ, 920 patients with intermittent claudication (ankle brachial index < 0.9) completed two questionnaires (Spanish version of the WIQ and European Quality of Life 5 Dimension [EQ-5D]). The validity of the WIQ was determined by correlating WIQ and EQ-5D. Test-retest reliability and internal consistency were determined using the intra-class correlation coefficient (ICC) and Cronbach's alpha, respectively. The three domains of the WIQ were moderately correlated with the EQ-5D health outcome (r = 0.54 to 0.60; p < 0.001). Test-retest reliabilities ranged from ICC = 0.89 to 0.91 and internal consistency (Cronbach's alpha = 0.92) was high. The Spanish version of the WIQ for European Spanish patients was valid and reproducible, suggesting that it could be used in Spanish patients with intermittent claudication.

    The aim of this study was to validate the newly developed shortened Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) in a sample of children with drug-resistant epilepsy. Data came from 136 children enrolled in the Impact of Pediatric Epilepsy Surgery on Health-Related Quality of Life Study (PEPSQOL), a multicenter prospective cohort study. Confirmatory factor analysis was used to assess the higher-order factor structure of the QOLCE-55. Convergent and divergent validity was assessed by correlating subscales of the KIDSCREEN-27 with the QOLCE-55. Measurement equivalence of the QOLCE-55 was evaluated using multiple-group confirmatory factor analysis of children with drug-resistant epilepsy from PEPSQOL versus children with new-onset epilepsy from HERQULES (Health-Related Quality of Life in Children with Epilepsy Study). The higher-order factor structure of the QOLCE-55 demonstrated adequate fit: Comparative Fit Index (CFI) = 0.948; Tucker-Lewis Index (TLI) = 0.946; Root Mean Square of Approximation (RMSEA) = 0.060 (90% confidence interval [CI] 0.054-0.065); Weighted Root Mean Square Residuals (WRMR) = 1.247. Higher-order factor loadings were strong, ranging from λ = 0.74 to 0.81. Internal consistency reliability was excellent (α = 0.97, subscales α > 0.82). QOLCE-55 subscales demonstrated moderate to strong correlations with similar subscales of the KIDSCREEN-27 (ρ = 0.43-0.75) and weak to moderate correlations with dissimilar subscales (ρ = 0.25-0.42). The QOLCE-55 demonstrated partial measurement equivalence at the level of strict invariance - χ 2 (2,823) = 3,727.9, CFI = 0.961, TLI = 0.962, RMSEA = 0.049 (0.044, 0.053), WRMR = 1.834. The findings provide support for the factor structure of the QOLCE-55 and contribute to its robust psychometric profile as a reliable and valid measure. Researchers and health practitioners should consider the QOLCE-55 as a viable option for reducing respondent burden when assessing health-related quality of life

    To ensure optimal clinical performance of digital mammography, it is necessary to obtain images with high spatial resolution and low noise, keeping radiation exposure as low as possible. These requirements directly affect the interpretation of radiologists. The quality of a digital image should be assessed using objective measurements. In general, these methods measure the similarity between a degraded image and an ideal image without degradation (ground-truth), used as a reference. These methods are called Full-Reference Image Quality Assessment (FR-IQA). However, for digital mammography, an image without degradation is not available in clinical practice; thus, an objective method to assess the quality of mammograms must be performed without reference. The purpose of this study is to present a Normalized Anisotropic Quality Index (NAQI), based on the Rényi entropy in the pseudo-Wigner domain, to assess mammography images in terms of spatial resolution and noise without any reference. The method was validated using synthetic images acquired through an anthropomorphic breast software phantom, and the clinical exposures on anthropomorphic breast physical phantoms and patient's mammograms. The results reported by this noreference index follow the same behavior as other well-established full-reference metrics, e.g., the peak signal-to-noise ratio (PSNR) and structural similarity index (SSIM). Reductions of 50% on the radiation dose in phantom images were translated as a decrease of 4dB on the PSNR, 25% on the SSIM and 33% on the NAQI, evidencing that the proposed metric is sensitive to the noise resulted from dose reduction. The clinical results showed that images reduced to 53% and 30% of the standard radiation dose reported reductions of 15% and 25% on the NAQI, respectively. Thus, this index may be used in clinical practice as an image quality indicator to improve the quality assurance programs in mammography; hence, the proposed method reduces the subjectivity

    The aim of this research was to examine the association between body mass index, physical activity, adherence to the Mediterranean diet, and health-related quality of life in a sample of Spanish adolescents. The study involved 456 adolescents aged between 11 and 14 years. They completed questionnaires on the Mediterranean diet (KIDMED), physical activity (Physical Activity Questionnaire for Older Children [PAQ-C]), and quality of life (KIDSCREEN-27). Body mass index was calculated. Hierarchical linear regression analyses were used to determine whether health-related quality of life could be predicted by the measured variables. The variables were analyzed in a stepwise manner, with Mediterranean diet entered in the first step, body mass index in the second, and physical activity in the third. Mediterranean diet accounted for 4.6% of the variance in adolescent's health-related quality of life, with higher adherence to the Mediterranean diet predicting higher health-related quality of life-scores. Body mass index accounted for a further 4.1% of the variance, with a higher body mass index predicting lower health-related quality of life scores. Finally, physical activity explained an additional 11.3% of the variance, with a higher level of physical activity being associated with higher health-related quality of life scores. Together, these variables explained 20% of the variance in the adolescents' health-related quality of life. Physical activity, body mass index, and adherence to the Mediterranean diet are important components to consider when targeting improvements in the health-related quality of life of adolescents, with physical activity representing the component with the greatest influence.

    To compare the visual function and the answers to a questionnaire of quality of life of patients wearing a progressive contact lens or eyeglasses. The Focus Progressive contact lens had been fitted in 35 patients with far visual acuity with progressive-addition eyeglasses equal to zero (log MAR) and near J1 (Jaeger). The far and near visual acuities and the measurement of contrast sensitivity were compared when the patients were wearing the eyeglasses or the contact lens and the patients' results of the scores of the quality of life questionnaire (NEI VFQ-25) were analyzed statistically considering the type of ametropy and the age. The far and near visual acuities and the contrast sensitivity measurement were worse with the contact lens than with eyeglasses. The answers to the questionnaire did not differ when were comparing the same patients wearing eyeglasses or contact lens, no matter the type of ametropy. The myopic and the hyperopic subgroups had worse answers to the quality of life questionnaire when corrected with the contact lens than with eyeglasses, both with age equal to or less than their median. The visual function was worse with the contact lens. The type of ametropy did not influence the answers to the quality of life questionnaire considering the optical correction, but age did.

    Spinal deformities are commonly associated with poor health-related quality of life (HRQOL). Several questionnaires (eg, Scoliosis Research Society-24 [SRS-24] and Scoliosis Research Society-22 [SRS-22]) have been developed to evaluate HRQOL in these conditions. In adults as well as during growth, the HRQOL is considered one of the most relevant outcomes of both conservative and surgical treatments. Rasch analysis is a powerful statistical technique for developing high-quality and valid questionnaires. The SRS-24 and SRS-22 have been evaluated using the Rasch analysis but showed poor measurement properties. Thus, a proper measure of HRQOL in people with a spine condition is still missing. This study aimed to develop a new questionnaire that is totally Rasch consistent for measuring the HRQOL in young people with a spine condition. This is a cross-sectional study for developing a new HRQOL measure. A total of 402 participants with adolescent idiopathic scoliosis or Scheuermann juvenile kyphosis were included in the study. The outcome measure used was the Italian Spine Youth Quality of Life (ISYQOL) questionnaire. The study consisted of different stages: a conventional approach content analysis, an opinion poll among clinicians trained in spine deformities, and the Rasch analysis (partial credit model). The Rasch analysis showed that all items of the ISYQOL questionnaire had ordered thresholds and a good fit to the model. Differential item functioning was present for Item 1, with bracing only, and was solved with a conventional items splitting procedure. The ISYQOL item map spans an adequate range of HRQOL. The principal component analysis for Rasch residuals showed, in practical terms, the ISYQOL unidimensionality. The reliability of ISYQOL was high enough so that approximately three significantly different levels of HRQOL could be discerned. Two questionnaire versions were provided for patients with and without the brace, respectively. ISYQOL is the first HRQOL

    The aim of this study was to conduct a systematic review of self-administered knee-disability functional assessment questionnaires adapted to Spanish, analysing the quality of the transcultural adaptation procedure and the psychometric properties of the new version. A search was conducted in the main biomedical databases to find knee-function assessment scales adapted into Spanish, in order to assess their questionnaire adaptation process as well as their psychometric properties. Ten scales were identified; 3 for lower limb: 2 for any type of pathologies (Lower Limb Functional Index [LLFI]; Lower Extremity Functional Scale [LEFS]) and 1 specific for arthrosis (Arthrosis des Membres Inférieurs et Qualité de vie [AMICAL]); Other 3 for knee and hip pathologies (Western Ontario and McMaster Universities Osteoarthritis [WOMAC] index; Osteoarthritis Knee and Hip Quality of Life [OAKHQOL] questionnaire; Hip and Knee Questionnaire [HKQ]), and other 4 for knee: 2 general scales (Knee Injury and Osteoarthritis Outcome Score [KOOS]; Knee Society Clinical Rating System [KSS]) and 2 specifics (Victorian Institute of Sport Assessment [VISA-P] questionnaire for patients with patellar tendinopathy and Kujala Score for patellofemoral pain). The transcultural adaptation procedure was satisfactory, albeit somewhat less rigorous for HKQ and LLFI. In no study were all psychometric properties assessed. Reliability was analyzed in all cases, except in KSS. Validity was measured in all questionnaires. The transcultural adaptation procedure was satisfactory and the psychometric properties analysed were similar to both the original version and other versions adapted to other languages.

    Utilization indices exist to measure quantity of prenatal care, but currently there is no published instrument to assess quality of prenatal care. The purpose of this study was to develop and test a new instrument, the Quality of Prenatal Care Questionnaire (QPCQ). Data for this instrument development study were collected in five Canadian cities. Items for the QPCQ were generated through interviews with 40 pregnant women and 40 health care providers and a review of prenatal care guidelines, followed by assessment of content validity and rating of importance of items. The preliminary 100-item QPCQ was administered to 422 postpartum women to conduct item reduction using exploratory factor analysis. The final 46-item version of the QPCQ was then administered to another 422 postpartum women to establish its construct validity, and internal consistency and test-retest reliability. Exploratory factor analysis reduced the QPCQ to 46 items, factored into 6 subscales, which subsequently were validated by confirmatory factor analysis. Construct validity was also demonstrated using a hypothesis testing approach; there was a significant positive association between women's ratings of the quality of prenatal care and their satisfaction with care (r = 0.81). Convergent validity was demonstrated by a significant positive correlation (r = 0.63) between the "Support and Respect" subscale of the QPCQ and the "Respectfulness/Emotional Support" subscale of the Prenatal Interpersonal Processes of Care instrument. The overall QPCQ had acceptable internal consistency reliability (Cronbach's alpha = 0.96), as did each of the subscales. The test-retest reliability result (Intra-class correlation coefficient = 0.88) indicated stability of the instrument on repeat administration approximately one week later. Temporal stability testing confirmed that women's ratings of their quality of prenatal care did not change as a result of giving birth or between the early postpartum

    Backgrounds/Objectives A discussion and analysis of factors that contribute to nurses’ happiness index can be useful in developing effective interventions to improve nurses’ enthusiasm, sense of honor and pride and to improve the efficiency and quality of medical services. Methods In this study, 206 registered nurses at the 2011 annual encounter for 12 Hanchuan hospitals completed a questionnaire survey that covered three aspects of the well-being index and thus served as a comprehensive well-being and general information tool. Results Based on their index score, the nurses’ overall happiness level was moderate. The dimensions of the happiness index are listed in descending order of their contribution to the nurses’ comprehensive happiness levels: health concerns, friendly relationships, self-worth, altruism, vitality, positive emotions, personality development, life satisfaction and negative emotions. Four variables (positive emotion, life satisfaction, negative emotions, and friendly relationships) jointly explained 47.80% of the total variance of the happiness index; positive emotions had the greatest impact on the happiness index. Conclusions Appropriate nursing interventions can improve nurses’ happiness index scores, thereby increasing nurses’ motivation and promoting the development of their nursing practice. PMID:26680594

  6. A ranking index for quality assessment of forensic DNA profiles forensic DNA profiles

    PubMed Central

    2010-01-01

    Background Assessment of DNA profile quality is vital in forensic DNA analysis, both in order to determine the evidentiary value of DNA results and to compare the performance of different DNA analysis protocols. Generally the quality assessment is performed through manual examination of the DNA profiles based on empirical knowledge, or by comparing the intensities (allelic peak heights) of the capillary electrophoresis electropherograms. Results We recently developed a ranking index for unbiased and quantitative quality assessment of forensic DNA profiles, the forensic DNA profile index (FI) (Hedman et al. Improved forensic DNA analysis through the use of alternative DNA polymerases and statistical modeling of DNA profiles, Biotechniques 47 (2009) 951-958). FI uses electropherogram data to combine the intensities of the allelic peaks with the balances within and between loci, using Principal Components Analysis. Here we present the construction of FI. We explain the mathematical and statistical methodologies used and present details about the applied data reduction method. Thereby we show how to adapt the ranking index for any Short Tandem Repeat-based forensic DNA typing system through validation against a manual grading scale and calibration against a specific set of DNA profiles. Conclusions The developed tool provides unbiased quality assessment of forensic DNA profiles. It can be applied for any DNA profiling system based on Short Tandem Repeat markers. Apart from crime related DNA analysis, FI can therefore be used as a quality tool in paternal or familial testing as well as in disaster victim identification. PMID:21062433

    Skin toxicity (hand-foot syndrome/hand-foot skin reaction, HFS/R) related to antineoplastic therapy is a significant issue in oncology practice, with potentially large impacts on health-related quality of life (HRQL). A patient-reported questionnaire, the hand-foot skin reaction and quality of life (HF-QoL) questionnaire was developed to measure the HFS/R symptoms associated with cancer therapeutic agents and their effect on daily activities. The validity and reliability of the HF-QoL questionnaire was tested in a randomized trial of capecitabine with sorafenib/placebo in 223 patients with locally advanced/metastatic breast cancer. Other measures completed included patient ratings of condition severity, the Functional Assessment of Cancer Therapy-Breast cancer (FACT-B), and the clinician-rated National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 3.0, hand-foot skin reaction grade. The psychometric properties of the HF-QoL tested included structural validity, internal consistency, construct validity, discriminant validity, and responsiveness. Finally, the minimal clinically important difference (MCID) was estimated. The HF-QoL instrument comprises a 20-item symptom scale and an 18-item daily activity scale. Each scale demonstrated excellent measurement properties and discriminated between NCI-CTCAE grade and patient-rated condition severity with large effect sizes. The daily activity scale had excellent internal consistency and correlated with the FACT-B and HF-QoL symptom scores. Both HF-QoL scale scores increased linearly with increasing patient-rated condition severity. The MCIDs were estimated as 5 units for daily activities and 8 units for symptoms mean scores. The HF-QoL was sensitive to symptoms and HRQL issues associated with HFS/R among participants treated with capecitabine with and without sorafenib. The HF-QoL appears suitable for assessing the HRQL impairment associated with HFS/R to cancer therapies. Skin

    This study analyzes the psychometric properties of the Portuguese version of the Quality of Life Questionnaire (QOL-Q; Quality of Life Questionnaire Manual - 1993 Manual and 2004 Revision. 2004, IDS Publishing Company, Worthington, OH; Schalock & Keith 2004). The analysis of the factorial structure was carried out on a sample of 304 adults with intellectual disabilities, through the use of confirmatory (CFA) and exploratory (EFA) factor analysis. The relationships of the QOL-Q with life satisfaction and self-concept measures were determined in groups composed of respectively 72 and 78 adults with intellectual disabilities. Confirmatory factorial analysis indicated a poor adjustment of the original factor structure to the Portuguese data. EFA indicated the existence of four factors, which include 30 items, and that were also supported by CFA. The total score of the QOL-Q revealed a reduced correlation with life satisfaction, and a moderate correlation with the self-concept. The Portuguese version of the QOL-Q shows satisfactory psychometric properties, but also some limitations. © 2012 Blackwell Publishing Ltd.

    Success in the remediation of mine spoil depends largely on the selection of appropriate tree species. The impacts of remediation on mine soil quality cannot be sufficiently assessed by individual soil properties. However, combination of soil properties into an integrated soil quality index provides a more holistic status of reclamation potentials of tree species. Remediation potentials of four tree species (Acacia auriculiformis, Cassia siamea, Dalbergia sissoo, and Leucaena leucocephala) were studied on reclaimed coal mine overburden dumps of Jharia coalfield, Dhanbad, India. Soil samples were collected under the canopies of the tree species. Comparative studies on the properties of soils in the reclaimed and the reference sites showed improvements in soil quality parameters of the reclaimed site: coarse fraction (-20.4%), bulk density (-12.8%), water holding capacity (+0.92%), pH (+25.4%), EC (+2.9%), cation exchange capacity (+46.6%), organic carbon (+91.5%), N (+60.6%), P (+113%), K (+19.9%), Ca (+49.6%), Mg (+12.2%), Na (+19.6%), S (+46.7%), total polycyclic aromatic hydrocarbons (-71.4%), dehydrogenase activity (+197%), and microbial biomass carbon (+115%). Principal component analysis (PCA) was used to identify key mine soil quality indicators to develop a soil quality index (SQI). Selected indicators include: coarse fraction, pH, EC, soil organic carbon, P, Ca, S, and dehydrogenase activity. The indicator values were converted into a unitless score (0-1.00) and integrated into SQI. The calculated SQI was significantly (P<0.001) correlated with tree biomass and canopy cover. Reclaimed site has 52-93% higher SQI compared to the reference site. Higher SQI values were obtained for sites reclaimed with D.sissoo (+93.1%) and C.siamea (+86.4%). Copyright © 2015 Elsevier B.V.

    Coeliac disease (CD) is a chronic immune-mediated disease in genetically susceptible individuals, induced by ingested gluten. The treatment for CD is a lifelong gluten-free diet (GFD). The GFD involves restrictions in diet that may impact on a person's Health-Related Quality of Life (HRQoL). The aim of the present study was to develop the Coeliac Disease Quality of Life questionnaire (CDQL): a comprehensive CD-specific HRQoL measure that can be completed by children, adolescents, and adults or by proxy. The questionnaire was developed in three phases. In phase 1, focus group methods and qualitative analysis of verbatim transcripts generated CD-specific items for a prototype instrument to sensitively captured patient concerns. In phase 2, CD patients completed the prototype CDQL. The questionnaire was refined through analysis of data and cognitive interviewing. In phase 3, the final version of the CDQL was answered by Danish respondents. The psychometric properties of the CDQL were assessed, and the HRQoL data were analyzed. The CDQL was completed by 422 respondents. The CDQL has 12 patient background items, 2 generic HRQoL items, and 30 CD-specific HRQoL item. The CD-specific HRQoL items were distributed on eight scales with acceptable to excellent reliability. Comprehensiveness and understandability was shown by feedback from cognitive interviewing from children, adolescents, and adults. Content validity was ensured by involving patients and clinicians in the development of the questionnaire. Sensitivity of the questionnaire was demonstrated in differences found between children, adolescents, and adult's perception of their HRQoL in relation to having CD. The CDQL comprehensively measures HRQoL in CD, and is psychometrically robust. The questionnaire may prove useful in tracking HRQoL in CD across age groups.

    The aim of this study was to develop and evaluate the validity and reliability of a quality-of-life (QoL) questionnaire for patients with oral potentially malignant disorders (OPMDs). For item generation, 15 personal interviews and three focus group discussions were conducted with OPMD patients existing QoL questionnaires were reviewed, and inputs from specialist clinicians (n = 10) were considered. Data collected from patients were analyzed by using NVivo. This led to the identification of themes, item writing, scaling, item reduction, formatting, and pretesting of the newly developed questionnaire. The validity and reliability of the questionnaire were assessed in a separate sample of 300 patients (150 each of patients with OPMD and healthy individuals). Sixty items were generated from the qualitative data and by reviewing existing questionnaires. After item reduction, the final questionnaire comprised 20 questions, which could be categorized under four domains. Exploratory factor analysis revealed a four-factor structure conforming to the four domains. The OPMD QoL questionnaire exhibited good discriminant and convergent validity, with OPMD patients reporting poorer QoL compared with healthy individuals and correlating significantly with existing questionnaires designed for similar purposes respectively. Our OPMD QoL questionnaire was found to be valid and reliable. We recommend that it be applied in epidemiologic and treatment studies of these disorders. Copyright © 2016 Elsevier Inc.

    In the last decades, several instruments have been used to evaluate the impact of oral health problems on the oral health-related quality of life (OHRQoL) of individuals. However, some instruments lack thorough methodological validation or present conceptual differences that hinder comparisons with instruments. Thus, it can be difficult to clinicians and researchers to select a questionnaire that accurately reflect what are really meaningful to individuals. This short communication aimed to discuss the importance of use an appropriate checklist to select an instrument with a good methodological quality. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was developed to provide tools for evidence-based instrument selection. The COSMIN checklist comprises ten boxes that evaluate whether a study meets the standard for good methodological quality and two additional boxes to meet studies that use the Item Response Theory method and general requirements for results generalization, resulting in four steps to be followed. In this way, it is required at least some expertise in psychometrics or clinimetrics to a wide-ranging use of this checklist. The COSMIN applications include its use to ensure the standardization of cross-cultural adaptations and safer comparisons between measurement studies and evaluation of methodological quality of systematic reviews of measurement properties. Also, it can be used by students when training about measurement properties and by editors and reviewers when revising manuscripts on this topic. The popularization of COSMIN checklist is therefore necessary to improve the selection and evaluation of health measurement instruments.

    All six ecosystem initiatives evolved from many years of federal, provincial, First Nation, local government and community attention to the stresses on sensitive habitats and species, air and water quality, and the consequent threats to community livability. This paper assesses water quality aspect for the ecosystem initiatives and employs newly developed Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) which provides a convenient mean of summarizing complex water quality data that can be easily understood by the public, water distributors, planners, managers and policy makers. The CCME WQI incorporates three elements: Scope - the number of water quality parameters (variables) not meeting water quality objectives (F(1)); Frequency - the number of times the objectives are not met (F(2)); and Amplitude. the extent to which the objectives are not met (F(3)). The index produces a number between 0 (worst) to 100 (best) to reflect the water quality. This study evaluates water quality of the Mackenzie - Great Bear sub-basin by employing two modes of objective functions (threshold values): one based on the CCME water quality guidelines and the other based on site-specific values that were determined by the statistical analysis of the historical data base. Results suggest that the water quality of the Mackenzie-Great Bear sub-basin is impacted by high turbidity and total (mostly particulate) trace metals due to high suspended sediment loads during the open water season. Comments are also provided on water quality and human health issues in the Mackenzie basin based on the findings and the usefulness of CCME water quality guidelines and site specific values.

    The MacNew health-related quality of life questionnaire was designed to assess feelings about how heart disease affects their daily physical, emotional and social functioning in patients with 1 of the 3 major coronary artery diagnoses, stable coronary artery disease (CAD) with angina, ST-elevation myocardial infarction (STEMI), and ischemic heart failure (HF). The aim of this study was to determine the reliability and validity of the Polish version of the MacNew in patients with CAD. Patients with CAD completed a self-report sociodemographic and clinical ques-tionnaire: the MacNew, the Short-Form 36 Health Survey, and HADS at baseline; 10% of the patients completed each questionnaire 2 weeks later. We studied patients with stable CAD with angina (n = 115), with STEMI (n = 112), and with ischemic HF (n = 105). Internal consistency reliability was demonstrated with Cronbach's a from 0.86 to 0.95 for the MacNew global scale and subscales. The original 3-factor structure was confirmed for the Polish version of the MacNew explaining 53.5% of the variance. Convergent validity of similar MacNew and SF-36 subscales was confirmed in the total group and in each diagnosis. Discriminant validity with the SF-36 health transition was fully confirmed in the total group and in patients with HF and partially confirmed in patients with stable CAD with angina or myocardial infarction. The Polish MacNew health-related quality of life questionnaire can be recommended in patients with stable CAD with angina, myocardial infarction and HF.

    Background: In the past few decades, Indoor Air Pollution (IAP) has become a primary concern to the point. It is increasingly believed to be of equal or greater importance to human health compared to ambient air. However, due to the lack of comprehensive indices for the integrated assessment of indoor air quality (IAQ), we aimed to develop a novel, Fuzzy-Based Indoor Air Quality Index (FIAQI) to bridge the existing gap in this area. Methods: We based our index on fuzzy logic, which enables us to overcome the limitations of traditional methods applied to develop environmental quality indices. Fifteen parameters, including the criteria air pollutants, volatile organic compounds, and bioaerosols were included in the FIAQI due mainly to their significant health effects. Weighting factors were assigned to the parameters based on the medical evidence available in the literature on their health effects. The final FIAQI consisted of 108 rules. In order to demonstrate the performance of the index, data were intentionally generated to cover a variety of quality levels. In addition, a sensitivity analysis was conducted to assess the validity of the index. Results: The FIAQI tends to be a comprehensive tool to classify IAQ and produce accurate results. Conclusion: It seems useful and reliable to be considered by authorities to assess IAQ environments. PMID:27114985

    The Children's Dermatology Life Quality Index (CDLQI) evaluates the impact of skin diseases on the patient's quality of life. The purpose of the study was to translate and to validate the CDLQI into Serbian. The CDLQI was translated into Serbian following international recommendations for translation and cultural adaptation. The validation study was carried out on a large cohort of secondary schoolchildren who self-reported acne. Translating the CDLQI consisted of forward translation, reconciliation, back translation, back-translation review, and cognitive debriefing. The good internal consistency of the scale was demonstrated with a Cronbach alpha coefficient of 0.87. A Spearman correlation coefficient of 0.66 between the CDLQI and the Cardiff Acne Disability Index (CADI) was deemed satisfactory to demonstrate concurrent validity. The translation, cross-cultural adaptation, and psychometric qualities of the CDLQI were satisfactory, enabling its application in clinical practice and future studies.

    OBJECTIVE To describe development and initial psychometric testing of an owner-reported questionnaire designed to standardize measurement of general quality of life (QOL) in dogs with cancer. DESIGN Key-informant interviews, questionnaire development, and field trial. SAMPLE Owners of 25 dogs with cancer for item development and pretesting and owners of 90 dogs with cancer for reliability and validity testing. PROCEDURES Standard methods for development and testing of questionnaire instruments intended to measure subjective states were used. Items were generated, selected, scaled, and pretested for content, meaning, and readability. Response items were evaluated with exploratory factor analysis and by assessing internal consistency (Cronbach α) and convergence with global QOL as determined with a visual analog scale. Preliminary tests of stability and responsiveness were performed. RESULTS The final questionnaire-which was named the Canine Owner-Reported Quality of Life (CORQ) questionnaire-contained 17 items related to observable behaviors commonly used by owners to evaluate QOL in their dogs. Several items pertaining to physical symptoms performed poorly and were omitted. The 17 items were assigned to 4 factors-vitality, companionship, pain, and mobility-on the basis of the items they contained. The CORQ questionnaire and its factors had high internal consistency (Cronbach α = 0.68 to 0.90) and moderate to strong correlations (r = 0.49 to 0.71) with global QOL as measured on a visual analog scale. Preliminary testing indicated good test-retest reliability and responsiveness to improvements in overall QOL. CONCLUSIONS AND CLINICAL RELEVANCE The CORQ questionnaire was a valid, reliable owner-reported questionnaire that measured general QOL in dogs with cancer and showed promise as a clinical trial outcome measure for quantifying changes in individual dog QOL occurring in response to cancer treatment and progression.

    Background Multi attribute utility instruments (MAUIs) are preference-based measures that comprise a health state classification system (HSCS) and a scoring algorithm that assigns a utility value to each health state in the HSCS. When developing a MAUI from a health-related quality of life (HRQOL) questionnaire, first a HSCS must be derived. This typically involves selecting a subset of domains and items because HRQOL questionnaires typically have too many items to be amendable to the valuation task required to develop the scoring algorithm for a MAUI. Currently, exploratory factor analysis (EFA) followed by Rasch analysis is recommended for deriving a MAUI from a HRQOL measure. Aim To determine whether confirmatory factor analysis (CFA) is more appropriate and efficient than EFA to derive a HSCS from the European Organisation for the Research and Treatment of Cancer’s core HRQOL questionnaire, Quality of Life Questionnaire (QLQ-C30), given its well-established domain structure. Methods QLQ-C30 (Version 3) data were collected from 356 patients receiving palliative radiotherapy for recurrent/metastatic cancer (various primary sites). The dimensional structure of the QLQ-C30 was tested with EFA and CFA, the latter informed by the established QLQ-C30 structure and views of both patients and clinicians on which are the most relevant items. Dimensions determined by EFA or CFA were then subjected to Rasch analysis. Results CFA results generally supported the proposed QLQ-C30 structure (comparative fit index =0.99, Tucker–Lewis index =0.99, root mean square error of approximation =0.04). EFA revealed fewer factors and some items cross-loaded on multiple factors. Further assessment of dimensionality with Rasch analysis allowed better alignment of the EFA dimensions with those detected by CFA. Conclusion CFA was more appropriate and efficient than EFA in producing clinically interpretable results for the HSCS for a proposed new cancer-specific MAUI. Our findings suggest

    2009-01-01

    Background Chronic kidney disease (CKD) is a serious public health problem in Taiwan and the world. The most effective, affordable treatments involve early prevention/detection/intervention, requiring screening. Successfully implementing CKD programs requires good patient participation, affected by patient perceptions of screening service quality. Service quality improvements can help make such programs more successful. Thus, good tools for assessing service quality perceptions are important. Aim: to investigate using a modified SERVQUAL questionnaire in assessing patient expectations, perceptions, and loyalty towards kidney disease screening service quality. Method 1595 kidney disease screening program patients in Taichung City were requested to complete and return a modified kidney disease screening SERVQUAL questionnaire. 1187 returned them. Incomplete ones (102) were culled and 1085 were chosen as effective for use. Paired t-tests, correlation tests, ANOVA, LSD test, and factor analysis identified the characteristics and factors of service quality. The paired t-test tested expectation score and perception score gaps. A structural equation modeling system examined satisfaction-based components' relationships. Results The effective response rate was 91.4%. Several methods verified validity. Cronbach's alpha on internal reliability was above 0.902. On patient satisfaction, expectation scores are high: 6.50 (0.82), but perception scores are significantly lower 6.14 (1.02). Older patients' perception scores are lower than younger patients'. Expectation and perception scores for patients with different types of jobs are significantly different. Patients higher on education have lower scores for expectation (r = -0.09) and perception (r = -0.26). Factor analysis identified three factors in the 22 item SERVQUAL form, which account for 80.8% of the total variance for the expectation scores and 86.9% of the total variance for the satisfaction scores.

    Methods: Systematic literature searches were performed to identify self administered shoulder disability questionnaires. A checklist was developed to evaluate and compare the clinimetric quality of the instruments. Results: Two reviewers identified and evaluated 16 questionnaires by our checklist. Most studies were found for the Disability of the Arm, Shoulder, and Hand scale (DASH), the Shoulder Pain and Disability Index (SPADI), and the American Shoulder and Elbow Surgeons Standardised Shoulder Assessment Form (ASES). None of the questionnaires demonstrated satisfactory results for all properties. Most questionnaires claim to measure several domains (for example, pain, physical, emotional, and social functioning), yet dimensionality was studied in only three instruments. The internal consistency was calculated for seven questionnaires and only one received an adequate rating. Twelve questionnaires received positive ratings for construct validity, although depending on the population studied, four of these questionnaires received poor ratings too. Seven questionnaires were shown to have adequate test-retest reliability (ICC >0.70), but five questionnaires were tested inadequately. In most clinimetric studies only small sample sizes (n<43) were used. Nearly all publications lacked information on the interpretation of scores. Conclusion: The DASH, SPADI, and ASES have been studied most extensively, and yet even published validation studies of these instruments have limitations in study design, sample sizes, or evidence for dimensionality. Overall, the DASH received the best ratings for its clinimetric properties. PMID:15020324

    In clinical translational research and molecular in vitro diagnostics, a major challenge in the detection of genetic mutations is overcoming artefactual results caused by the low-quality of formalin-fixed paraffin-embedded tissue (FFPET)-derived DNA (FFPET-DNA). Here, we propose the use of an 'internal quality control (iQC) index' as a criterion for judging the minimum quality of DNA for PCR-based analyses. In a pre-clinical study comparing the results from droplet digital PCR-based EGFR mutation test (ddEGFR test) and qPCR-based EGFR mutation test (cobas EGFR test), iQC index ≥ 0.5 (iQC copies ≥ 500, using 3.3 ng of FFPET-DNA [1,000 genome equivalents]) was established, indicating that more than half of the input DNA was amplifiable. Using this criterion, we conducted a retrospective comparative clinical study of the ddEGFR and cobas EGFR tests for the detection of EGFR mutations in non-small cell lung cancer (NSCLC) FFPET-DNA samples. Compared with the cobas EGFR test, the ddEGFR test exhibited superior analytical performance and equivalent or higher clinical performance. Furthermore, iQC index is a reliable indicator of the quality of FFPET-DNA and could be used to prevent incorrect diagnoses arising from low-quality samples.

    The aim of the study was to evaluate the clinical reliability of subjective sleep evaluation, based on sleep and psychometric questionnaires, by comparing the results with those obtained with laboratory-based video-polysomnography (V-PSG). Thirty consecutive Huntington disease (HD) patients were enrolled. Subjective evaluation of sleep included the Pittsburgh Sleep Quality Index (PSQI), the sleep questionnaire for HD (HDQ), the Epworth Sleepiness Scale, the Bologna questionnaire for sleepiness (BQ), the Berlin questionnaire, and the RBD questionnaire; the International Restless Legs Syndrome Study Group scale was administered to patients with positive screening. The psychometric evaluation included the Zung Anxiety Scale, the short form of the Beck Depression Inventory, and the Maudsley Obsessive-Compulsive Inventory. All patients underwent V-PSG. In sleepiness evaluation, the Epworth score was above the cutoff in 6 subjects, and the BQ detected a "high risk" of sleepiness in 7 cases. The results were concordant in 24 and discordant in 5 cases. In the evaluation of sleep quality, the PSQI score was above the cutoff in 18 subjects. According to the HDQ, 10 subjects were poor sleepers. The results were concordant with the PSQI in 20 subjects. All comparisons between scale scores and PSG results showed poor or totally absent concordance between subjective and objective measures. The subjective evaluation of sleep in HD patients shows a poor correlation with PSG results. © 2017 S. Karger AG, Basel.

    In order to evaluate the water quality of one of the most polluted urban river in Malaysia, the Penchala River, performance of eight biotic indices, Biomonitoring Working Party (BMWP), BMWP Thai , BMWP Viet , Average Score Per Taxon (ASPT), ASPT Thai , BMWP Viet , Family Biotic Index (FBI), and Singapore Biotic Index (SingScore), was compared. The water quality categorization based on these biotic indices was then compared with the categorization of Malaysian Water Quality Index (WQI) derived from measurements of six water physicochemical parameters (pH, BOD, COD, NH 3 -N, DO, and TSS). The river was divided into four sections: upstream section (recreational area), middle stream 1 (residential area), middle stream 2 (commercial area), and downstream. Abundance and diversity of the macroinvertebrates were the highest in the upstream section (407 individual and H' = 1.56, respectively), followed by the middle stream 1 (356 individual and H' = 0.82). The least abundance was recorded in the downstream section (214 individual). Among all biotic indices, BMWP was the most reliable in evaluating the water quality of this urban river as their classifications were comparable to the WQI. BMWPs in this study have strong relationships with dissolved oxygen (DO) content. Our results demonstrated that the biotic indices were more sensitive towards organic pollution than the WQI. BMWP indices especially BMWP Viet were the most reliable and could be adopted along with the WQI for assessment of water quality in urban rivers.

    Patient Safety is a major public health problem worldwide and is responsibility of all those involved in health care. Establishing a Safety Culture has proved to be a factor that favors the integration of work teams, communication and construction of clear procedures in various organizations. Promote a culture of safety depends on several factors, such as organization, work unit and staff. Objective assessment of these factors will help to identify areas for improvement and establish strategic lines of action. [corrected] To adapt, validate and calibrate the questionnaire Culture of Quality in Health Services (CQHS) in Mexican population. A cross with a stratified representative sample of 522 health workers. The questionnaire was translated and adapted from Singer's. Content was validated by experts, internal consistency, confirmatory factorial validity and item calibration with Samejima's Graded Response Model. Convergent and divergent construct validity was confirmed from the CQHS, item calibration showed that the questionnaire is able to discriminate between patients and represent different levels of the hypothesized dimensions with greater accuracy and lower standard error. The CQHS is a valid and reliable instrument to assess patient safety culture in hospitals in Mexico. Copyright © 2013 SECA. Published by Elsevier Espana. All rights reserved.

    Only a few reports in the literature have described the use of specific instruments for assessing the quality of life in adolescents and young adults with cleft lip and palate (CLP). This condition markedly affects their lifestyle, even after surgical treatment. In the present study, we aimed to develop a quality-of-life assessment tool specifically designed for such patients with CLP. Our multidisciplinary team created a questionnaire focused on the physical, psychological, and social satisfaction of adolescents and young adults with CLP, which was adapted from 3 dimensions of the 36-item Short-Form Health Survey. The questionnaire was administered to a randomized sample of 40 adolescents and young adults (aged 16-24 years) with CLP who had completed treatment protocols and 40 (aged 16-24 years) who were not affected by CLP. The statistical results stated that the questionnaire had good reliability and validity; the Cronbach α coefficient was found to be 0.944. Moreover, factorial analysis confirmed the presence of 3 subscales that were the fundamental components of this questionnaire, which is consistent with the areas theoretically proposed and from which the items were designed and selected. Thus, we validated our novel questionnaire that was administered in the present study and proved its consistency. However, further investigations on a larger population would be useful to confirm these findings.

    To determine the psychological and social effects of kidney donation on kidney donors by using the short-form 36-item health survey (SF-36) as the quality-of-life questionnaire. A total of 104 living donor nephrectomies have been performed at Kobe University Hospital and Nishinomiya Prefectural Hospital. We mailed the questionnaires to donors or handed them out directly at the outpatient clinic. The first part of the questionnaire consisted of the SF-36 (limitations on physical functioning because of health problems) and the second part consisted of 15 questions about donation-related stress, expenses incurred, physical changes, and pre-existing factors such as relationship to the recipients. The SF-36 and the questionnaire about donor satisfaction were completed by 69 donors (48 women and 21 men; mean age 52.1 +/- 8.2 years), only 6 of whom (9%) reported minor complications with the donor operation. The SF-36 scores of our donors were not significantly different from that of the general U.S. population and U.S. donors. In some categories (physical functioning, role-physical, bodily pain, general health, vitality, and mental health), our donors scored slightly higher than the U.S. general population. Although 97% of the donors would make the same choice again, 3% believed that donating had had a negative impact on their health, and 16% reported negative financial consequences. The quality of life for kidney donors was not affected by donor nephrectomy. Living kidney transplantation seems to be suitable for the rescue of patients with end-stage renal disease. Better psychological and technical preparation for surgery and more consistent follow-up may reduce the negative outcomes even further.

    Exposure to deadlines at work is increasing in several countries and may affect health. We aimed to investigate cross-sectional and longitudinal associations between frequency of difficult deadlines at work and sleep quality. Study participants were knowledge workers, drawn from a representative sample of Danish employees who responded to a baseline questionnaire in 2006 (n = 363) and a follow-up questionnaire in 2007 (n = 302). Frequency of difficult deadlines was measured by self-report and categorized into low, intermediate, and high. Sleep quality was measured with a Total Sleep Quality Score and two indexes (Awakening Index and Disturbed Sleep Index) derived from the Karolinska Sleep Questionnaire. Analyses on the association between frequency of deadlines and sleep quality scores were conducted with multiple linear regression models, adjusted for potential confounders. In addition, we used multiple logistic regression models to analyze whether frequency of deadlines at baseline predicted caseness of sleep problems at follow-up among participants free of sleep problems at baseline. Frequent deadlines were cross-sectionally and longitudinally associated with poorer sleep quality on all three sleep quality measures. Associations in the longitudinal analyses were greatly attenuated when we adjusted for baseline sleep quality. The logistic regression analyses showed that frequent deadlines at baseline were associated with elevated odds ratios for caseness of sleep problems at follow-up, however, confidence intervals were wide in these analyses. Frequent deadlines at work were associated with poorer sleep quality among Danish knowledge workers. We recommend investigating the relation between deadlines and health endpoints in large-scale epidemiologic studies. Copyright © 2011 Wiley Periodicals, Inc.

    Background Lung cancer is one of the leading causes of cancer deaths. Treatment goals are the relief of symptoms and the increase of overall survival. With the rising number of treatment alternatives, the need for comparable assessments of health-related quality of life (HRQoL) parameters grows. The aim of this paper was to identify and describe measurement instruments applied in lung cancer patients under drug therapy. Methods We conducted a systematic literature review at the beginning of 2011 using the electronic database Pubmed. Results A total of 43 studies were included in the review. About 17 different measurement instruments were identified, including 5 generic, 5 cancer-specific, 4 lung cancer-specific and 3 symptom-specific questionnaires. In 29 studies at least 2 instruments were used. In most cases these were cancer and lung cancer-specific ones. The most frequently used instruments are the EORTC QLQ-C30 and its lung cancer modules LC13 or LC17. Only 5 studies combined (lung) cancer-specific questionnaires with generic instruments. Conclusions The EORTC-C30 and EORTC-LC13 are the most frequently used health-related quality of life measurement instruments in pharmacological lung cancer trials. PMID:23680096

    Short, self-report symptom questionnaires are useful in routine clinical situations for assessing the progress of disorders and the influence of interventions. The Voice Handicap Index-10 (VHI-10) and Vocal Performance Questionnaire (VPQ) are brief self-reported assessments of voice pathology, apparently useful in the general voice clinic population. Little is known of the structure or internal consistency of either tool, nor whether they correlate. This study carried out a substantial, systematic evaluation of their performance in the Laryngology office setting. 330 adult (222 women, 108 men) voice clinic attenders completed the VHI and the VPQ. The VHI-10 and VPQ each had a large, single principal component, high internal consistency, and were highly correlated (disattenuated r=0.91). The VHI-10 and the VPQ are similar, short, convenient, internally-consistent, unidimensional tools. The total VHI-10 or VPQ score is a good overall indicator of the severity of voice disorders.

    Recent changes within community pharmacy have seen a shift towards some pharmacies providing "value-added" services. However, providing high levels of service is resource intensive yet revenues from dispensing are declining. Of significance therefore, is how consumers perceive service quality (SQ). However, at present there are no validated and reliable instruments to measure consumers' perceptions of SQ in Australian community pharmacies. The aim of this study was to build a theory-grounded model of service quality (SQ) in community pharmacies and to create a valid survey instrument to measure consumers' perceptions of service quality. Stage 1 dealt with item generation using theory, prior research and qualitative interviews with pharmacy consumers. Selected items were then subjected to content validity and face validity. Stages 2 and 3 included psychometric testing among English-speaking adult consumers of Australian pharmacies. Exploratory factor analysis was used for item reduction and to explain the domains of SQ. In stage 1, item generation for SQ initially generated 113 items which were then refined, through content and face validity, down to 61 items. In stage 2, after subjecting the questionnaire to psychometric testing on the data from the first pharmacy (n = 374), the use of the primary dimensions of SQ was abandoned leaving 32 items representing 5 domains of SQ. In stage 3, the questionnaire was subject to further testing and item reduction in 3 other pharmacies (n = 320). SQ was best described using 23 items representing 6 domains: 'health and medicines advice', 'relationship quality', 'technical quality', 'environmental quality', 'non-prescription service', and 'health outcomes'. This research presents a theoretically-grounded and robust measurement scale developed for consumer perceptions of SQ in a community pharmacy. Copyright © 2018. Published by Elsevier Inc.

    To evaluate and determine prognostic factors of 5-year quality of life in patients with early rheumatoid arthritis (RA). A cohort of 191 patients with RA and disease duration < 1 year was prospectively followed over 5 years. The outcome measure was quality of life as assessed by the Arthritis Impact Measurement Scales 2 (AIMS2). Univariate analysis, then stepwise multiple logistic regression, was used to find independent baseline prognostic variables. After accounting for death, loss of followup, and missing data, 158 patients (82.72%) were included in the analysis. The mean AIMS2 physical, symptom, psychological, social interaction, and work scores after 5 years were 1.6 (range 0-6.88), 4.0 (0-10), 3.48 (0-9.22), 4.06 (0-8.69), and 1.87 (0-8.13), respectively. The AIMS2 physical component was significantly correlated with Health Assessment Questionnaire (HAQ) score at 5 years. Logistic regression analysis revealed that the baseline values able to predict the 5-year physical, psychological, symptom, social interaction, and work status were, respectively: HAQ score and erythrocyte sedimentation rate (ESR), body mass index (BMI), HAQ; erosion score and sex, HAQ; ESR and anti-perinuclear antibody; matrix metalloproteinase-3 (MMP3) level, joint space narrowing, and tender joint scores; HAQ score and age. The multidimensional structure of the AIMS2 allowed us to assess the 5-year health-related quality of life in early RA. Using this instrument as an outcome variable, prognostic factors were selected and varied widely depending on the evaluated domain. The baseline HAQ score was the best predictive factor of 4 of the 5 domains of the AIMS2.

    To develop and determine the reliability and validity of a vision-specific quality-of-life instrument (TL-VSQOL) designed to assess the impact of distance and near vision impairment in adults living in Timor-Leste. A vision-specific quality-of-life questionnaire was developed, piloted, and administered to 704 Timorese aged >or=40 years during a population-based eye health rapid assessment. Rasch analysis was performed on the data of 457 participants with presenting near vision worse than N8 (78.5%) and/or distance vision worse than 6/18 (69.8%). Unidimensionality, item fit to the model, response category performance, differential item functioning, and targeting of items to participants were assessed. Initially, the questionnaire lacked fit to the Rasch model. Removal of two items concerning emotional well-being resulted in a fit of the data (overall item-trait interaction: chi(2) (df) = 81 (51); mean (SD) person and item fit residual values: -0.30 (1.02) and -0.32 (1.46), and good targeting of person ability and item difficulty was evident. Poorer distance and near visual acuities were significantly associated with worse quality-of-life scores (P < 0.001). Person separation reliability was substantial (0.93), indicating that the instrument can discriminate between groups with normal and impaired vision. All 17 items were free of differential item functioning, and there was no evidence of multidimensionality. This 17-item TL-VSQOL has high reliability, construct, and criterion validity and effective targeting. It can effectively assess the impact on quality of life of adult Timorese with distance and near vision impairment. The TL-VSQOL could be adapted for use in other low-resource settings.

    To evaluate the reliability and validity of the improved version of the Patient Generated Index (PGI) in patients with low back pain. The PGI was administered to 90 patients attending care in 1 of 6 institutions in Norway and evaluated for reliability and validity. The questionnaire was given out to 61 patients for re-test purposes. The PGI was completed correctly by 80 (88.9%) patients and, of the 61 patients responding to the re-test, 50 (82.0%) completed both surveys correctly. PGI scores were approximately normally distributed, with a median of 40 (range 80), where 100 is the best possible quality of life. There were no floor or ceiling effects. The 5 most frequently listed areas affecting quality of life were pain, sleep, stiffness, socializing and housework. The test-retest intraclass correlation coefficient was 0.73. The smallest detectable changes for individual and group purposes were 32.8 and 4.6, respectively. The correlations between PGI scores and other instrument scores followed a priori hypotheses of low to moderate correlations. The PGI has evidence for reliability and validity in Norwegian patients with low back pain at the group level and may be considered for application in intervention studies when a comprehensive evaluation of quality of life is important. However, the smallest detectable change, of approximately 30 points, may be considered too large for individual purposes in clinical applications.

    Novel bibliometric indexes (commonly known as altmetrics) are gaining interest within the scientific community and might represent an important alternative measure of research quality and output. We evaluate how these new metrics correlate with established bibliometric indexes such as the impact factor (IF), currently used as a measure of scientific production as well as a criterion for scientific research funding, and how they might be helpful in assessing the impact of research. We calculated altmetrics scores for all the articles published at our institution during a single year and examined the correlation between altmetrics scores and IFs as a measure of research quality and impact in all departments. For all articles from the various departments published in a single year, the altmetrics score and the sum of all IFs showed a strong and significant correlation (Spearman's rho 0.88). The correlation was significant also when the major components of altmetrics, including Facebook, Twitter and Mendeley, were analyzed. The implementation of altmetrics has been found to be easy and effective at both the researcher and librarian levels. The novel bibliographic index altmetrics is consistent and reliable and can complement or be considered a valid alternative to standard bibliometric indexes to benchmark output and quality of research for academic and funding purposes.

    In Entre Ríos (Argentina), rice cultivation is carried out mainly in Vertisols. Several factors, such as the use of sodium bicarbonate waters for irrigation, the excessive tillage required, and the lack of proper planning for land use, mainly regarding the crop sequence, cause serious impacts on the soil and have an effect on sustainable agriculture. Thus, the development of methodologies to detect these impacts has become a priority. The aim of this study was to standardize soil quality indicators (SQI) and integrate them into an index to evaluate the impacts of the rice production system on soil, at the farm scale. The study was conducted in farms of the traditional rice cultivation area of Entre Ríos province, Argentina. We evaluated a minimum data set consisting of six indicators: structural stability and percolation, total organic matter content (TOM), exchangeable sodium content (ESC), electrical conductivity of saturation extract (ECe) and reaction of the soil (pH). From a database from 75 production lots, we determined the reference values, i.e. limits to ensure the maintenance of long-term productivity and the allowable thresholds for each indicator. The indicators were standardized and integrated into a soil quality index. Five ranges of soil quality were established: very low, low, moderate, high and very high, depending on the values assigned to each SQI. This index allowed differentiating the impact of different crop sequences and showed that the increased participation of rice crop in the rotation resulted in a deterioration of the soil structure due to the decrease in the TOM and to the cumulative increase in ESC caused by the sodium bicarbonate water used for irrigation. Soil management strategies should aim to increase TOM values and to reduce the input of sodium to the exchange complex. A rotation with 50% to 60% of pasture and 40 to 50% of agriculture with a participation of rice lower than 20 to 25% would allow the sustainability of the

    Quality of life (QoL) studies in heart transplant recipients (HTRs) using validated, quantitative, self-report questionnaires have reported poor QoL in approximately 20% of patients. This consecutive mixed methods study compared self-report questionnaires, the Medical Outcomes Study 36-item Short Form Health Survey (MOS SF-36) and the Atkinson Life Satisfaction Scale, with phenomenologically informed audiovisual (AV) qualitative interview data in 27 medically stable HTRs (70% male; age 53 ± 13.77 years; time since transplant 4.06 ± 2.42 years). Self-report questionnaire data reported poor QoL and more distress compared with previous studies and normative population samples; in contrast, 52% of HTRs displayed pervasive distress according to visual methodology. Using qualitative methods to assess QoL yields information that would otherwise remain unobserved by the exclusive use of quantitative QOL questionnaires.

    Patients with voice-related disorders are often treated by a multidisciplinary team including assessment by patient-reported outcome measures. The present paper aims at documenting the importance of including general health-related quality of life (HRQoL) measures to clinical investigations. The participants (N = 80 larynx cancer, N = 32 recurrent palsy, N = 23 dysfunctional, N = 75 degenerative/inflammation, N = 19 various) were included consecutively at the laryngology clinic at Haukeland University Hospital. In addition, HRQoL data were included from one national group with laryngectomies (N = 105), one group with various patients formerly treated for head and neck squamous cell carcinoma (N = 96), and one population-based reference group (N = 1956). Obtained were the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ), the Voice Handicap Index (VHI), and the Eysenck Personality Inventory (EPI) neuroticism scores. By analysis of variance, we have determined significant dependence of groups analyzing the sum global QoL/health index (F = 9.47; P <0.001), the functional HRQoL sum score (F 5,2373  = 7.14, P <0.001), and the symptom sum HRQoL scores (F 7,2381  = 8.13; P <0.001). In particular, patients with recurrent palsy and laryngeal cancer had lowered HRQoL. At the index levels, in particular dyspnea scores, were scored depending on larynx disease group (F 7,2288  = 24.4; P <0.001). The VHI score correlated with the EORTC H&N35 "speech" index with a common variance of 52%. VHI scores correlated with level of neuroticism with 8% common variance (P <0.001) and EORTC scores with 22% (P <0.001). In particular, among patients with voice-related disease, those with recurrent palsy and laryngeal cancer had lower HRQoL. Furthermore, the HRQoL and VHI scores were inversely tied to neuroticism.

    Skin conditions affect the quality of life (QoL) of patients and their family. To assess family members' QoL, a questionnaire uniquely designed for family members is necessary. We translated the Family Dermatology Life Quality Index (FDLQI), originally created and validated by Basra et al., into Japanese, and evaluated its reliability and validity. For psychometric evaluations, 150 dermatology patients and their family members were included. The Japanese version of the FDLQI showed high test-retest reliability (intraclass correlation coefficient = 0.95) and internal consistency reliability (Cronbach's alpha = 0.86). FDLQI scores significantly correlated with DLQI scores (r = 0.58, P < 0.01, Spearman's rho) and global question (GQ) which measured the patient's skin condition on a visual analog scale (r = 0.36, P < 0.01). Family members of patients with inflammatory skin diseases showed higher FDLQI scores than those with isolated lesions, but the difference was not statistically significant (P = 0.062, Mann-Whitney U-test). Responsiveness to change was demonstrated in a group in which the patient's skin condition was assessed as improved (n = 37, r = 0.46, P < 0.01) but not in that in which it became worse. The difference of the change between the two groups was statistically significant (P < 0.01). Additionally, the change in FDLQI scores and GQ were significantly correlated (r = 0.40, P < 0.01). Exploratory factor analysis suggested essential unidimensionality of the instrument. We showed acceptable validity and responsiveness of this Japanese version of FDLQI. Further clinical epidemiological studies are required to confirm this. © 2017 Japanese Dermatological Association.

    This paper proposes algorithms for iris segmentation, quality enhancement, match score fusion, and indexing to improve both the accuracy and the speed of iris recognition. A curve evolution approach is proposed to effectively segment a nonideal iris image using the modified Mumford-Shah functional. Different enhancement algorithms are concurrently applied on the segmented iris image to produce multiple enhanced versions of the iris image. A support-vector-machine-based learning algorithm selects locally enhanced regions from each globally enhanced image and combines these good-quality regions to create a single high-quality iris image. Two distinct features are extracted from the high-quality iris image. The global textural feature is extracted using the 1-D log polar Gabor transform, and the local topological feature is extracted using Euler numbers. An intelligent fusion algorithm combines the textural and topological matching scores to further improve the iris recognition performance and reduce the false rejection rate, whereas an indexing algorithm enables fast and accurate iris identification. The verification and identification performance of the proposed algorithms is validated and compared with other algorithms using the CASIA Version 3, ICE 2005, and UBIRIS iris databases.

    An approach to measuring environmental quality and trends in coal mining and industrial areas was attempted in this work. For this purpose, the establishment of a reference scale characterizing the status of environmental quality is proposed by developing an Environmental Quality Index (EQI). The methodology involves three main components: social research, the opinion of environmental experts, and the combination of new or existing indices. A survey of public opinion was carried out to identify the main environmental problems in the region of interest. Environmental experts carried out a survey, and the weights of specific environmental problems were obtained through a fuzzy Delphi method and pairwise comparison. The weight attributed to each environmental problem was computed, using new or existing indices (subindices) in the relevant literature. The EQI comprises a combination of the subindices with their own weights. The methodology was applied to a heavily industrialized coal basin in northwestern Macedonia, Greece. The results show that the new index may be used as a reliable tool for evaluating environmental quality in different areas. In addition, the study of EQI trends on an interannual basis can provide useful information on the efficiency of environmental policies already implemented by the responsible authorities.

    Developing professional values among nursing students is important because values are a significant predictor of the quality care that will be provided, the clients' recognition, and consequently the nurses' job satisfaction. The literature analysis showed that there is only one validated tool available in Turkish that examines both the personal and the professional values of nursing students. The aim of this study was to assess the reliability and validity of the Salford-Scott Nursing Values Questionnaire in Turkish. This study was a Turkish linguistic and cultural adaptation of a research tool. Participants and research context: The sample of this study consisted of 627 undergraduate nursing students from different geographical areas of Turkey. Two questionnaires were used for data collection: a socio-demographic form and the Salford-Scott Nursing Values Questionnaire. For the Salford-Scott Nursing Values Questionnaire, construct validity was examined using factor analyses. Ethical considerations: The study was approved by the Cumhuriyet University Faculty of Medicine Research Ethics Board. Students were informed that participation in the study was entirely voluntary and anonymous. Item content validity index ranged from 0.66 to 1.0, and the total content validity index was 0.94. The Kaiser-Meyer-Olkin measure of sampling was 0.870, and Bartlett's test of sphericity was statistically significant (x 2 = 3108.714, p < 0.001). Construct validity was examined using factor analyses and the six factors were identified. Cronbach's alpha was used to assess the internal consistency reliability and the value of 0.834 was obtained. Our analyses showed that the Turkish version of Salford-Scott Nursing Values Questionnaire has high validity and reliability.

    To analyse the psychometric properties of the Cervantes scale short-form (SF) in the peri- and post-menopausal periods. Outpatients women 45-65 years with menstrual problems associated with the climacteric syndrome were analysed. Original and SF versions of the Cervantes scale were administered along with the EuroQol-5D (EQ-5D) and work productivity and activity impairment questionnaire (WPAI) scales. Conceptual model, burden of administration, feasibility, reliability, criteria validity and construct validity were assessed. 317 women [55.7±5.3 years (mean±standard deviation)] were recruited: 75.4% were post- and 22.3% were peri-menopausal. The Cervantes-SF was completed in 2.5±1.6min, and 86% answered all items. Cronbach's α was 0.820, and ranged from 0.510 (Aging) to 0.918 (Vasomotor Symptoms) for individual dimensions. The scale structure matched the structure of the original version, χ(2)/(degrees of freedom)=3.6, Comparative Fit Index=0.848, Tucker-Lewis Index=0.850, and root mean square error of approximation=0.099, although differences were found between sexual activity statuses. Criteria validity was good (r=0.890), concurrent validity was congruent with a priori hypothesis using either the EQ-5D or the WPAI scales. The scale discriminated significantly the severity of both vasomotor and genital climacteric associated symptoms. The Cervantes-SF has shown good psychometric properties for measuring Health related quality of life in peri- and post-menopausal women who regularly attended gynaecology clinics in Spain.

    Determining suitability and vulnerability of groundwater quality for irrigation use is a key alarm and first aid for careful management of groundwater resources to diminish the impacts on irrigation. This study was conducted to determine the overall suitability of groundwater quality for irrigation use and to generate their spatial distribution maps in Elala catchment, Northern Ethiopia. Thirty-nine groundwater samples were collected to analyze and map the water quality variables. Atomic absorption spectrophotometer, ultraviolet spectrophotometer, titration and calculation methods were used for laboratory groundwater quality analysis. Arc GIS, geospatial analysis tools, semivariogram model types and interpolation methods were used to generate geospatial distribution maps. Twelve and eight water quality variables were used to produce weighted overlay and irrigation water quality index models, respectively. Root-mean-square error, mean square error, absolute square error, mean error, root-mean-square standardized error, measured values versus predicted values were used for cross-validation. The overall weighted overlay model result showed that 146 km2 areas are highly suitable, 135 km2 moderately suitable and 60 km2 area unsuitable for irrigation use. The result of irrigation water quality index confirms 10.26% with no restriction, 23.08% with low restriction, 20.51% with moderate restriction, 15.38% with high restriction and 30.76% with the severe restriction for irrigation use. GIS and irrigation water quality index are better methods for irrigation water resources management to achieve a full yield irrigation production to improve food security and to sustain it for a long period, to avoid the possibility of increasing environmental problems for the future generation.

    We examined the relationship between body mass index (BMI) and measures of tenderness, quality of life, and physical functioning in female fibromyalgia (FMS) patients. A random sample of 100 female FMS patients from a database of 550 FMS individuals was interviewed and assessed according to a structured questionnaire that included FMS-related symptoms, measures of tenderness (point count and dolorimetry), quality of life (SF-36), physical functioning, and BMI. Weight was defined as normal, overweight, and obesity according to BMI. Twenty-seven percent of the FMS patients had normal BMI, 28% were overweight, and 45% were obese. BMI was negatively correlated with quality of life (r = -0.205, P = 0.044) and tenderness threshold (r = -0.238, P = 0.021) and positively correlated with physical dysfunctioning (r = 0.202, P = 0.047) and point count (r = 0.261, P = 0.011). Obese FMS patients display higher pain sensitivity and lower levels of quality of life. In designing studies that explore factors affecting tenderness, BMI should be included in addition to sex, age, etc.

    Background Quality of life (QOL) and its measurement in cancer patients is becoming increasingly important. Breast cancer diagnosis and treatment are often associated with psychological distress and reduced QoL. In Arabic-speaking countries, QoL of patients with cancer is inadequately studied. The aim of this study was to test the reliability and validity of the Moroccan Arabic version of the European Organization for Research and Treatment of Cancer (EORTC) Breast Cancer-Specific Quality of Life Questionnaire (QLQ-BR23). Methods After translation and cross-cultural adaptation, the questionnaire was tested on breast cancer patients. The participants’ number for the test and the retest were 105 and 37 respectively. Internal consistency was tested using Cronbach’s alpha coefficient (α), the test-retest reliability using intraclass correlation coefficients (ICC). Construct validity was assessed by examining item-convergent and divergent validity. Results The questionnaire was administered to 105 patients. The mean age of patients was 48 years (SD: 16), 62.9% were married. 68.6% of all participants lived in urban area. The average time to complete the QLQ- BR23 was 15 min. Cronbach’s alpha coefficient, were all >0.7, with the exception of breast symptoms and arm symptoms. All items exceeded the 0.4 criterion for convergent validity except item 20 and 23 related to pain and skin problems in the affected breast respectively. Conclusion In general, the findings of this study indicated that the Moroccan Arabic version of the EORTC QLQ-BR23 is a reliable and valid supplementary measure of the QOL in breast cancer patients and can be used in clinical trials and studies of outcome research in oncology.

    The COMQ-12 questionnaire has been elaborated to evaluate the deterioration in the quality of life of the subjects suffering from chronic suppurative otitis media (CSOM) based on the reports of the patients themselves. This questionnaire is of special interest in that it allows to register the complaints of the patients stated by them in the order of priority beginning from those that are responsible for the most pronounced manifestations of the impairment in the quality of life. It, in turn, helps the medical practitioner to rationally organize the treatment of a concrete patient taking into consideration his or her individual expectations. At the current stage of the development and adaptation of the COMQ-12 questionnaire, the main emphasis is placed on the search for the possible range of the key scores and their normal values allowing to characterize the quality of life in the healthy population. The objective of the present work was to estimate the potential of the COMQ-12 questionnaire for the evaluation of the quality of life among the subjects having no signs of chronic suppurative otitis media. A total of 60 healthy volunteers were recruited for the study and asked to fill up the questionnaire. The following information was selected for the subsequent analysis: sex and age of the respondents, experience with having any ear-related problems other than those related to chronic suppurative otitis media in the course of the lifetime. The patients presenting with chronic suppurative otitis media were excluded from the study. The score values ranged from 0 to 14 among the entire set of the respondents (mean 3.55). The resulting score of the respondents' condition was 5 and less in 75% of the cases; it achieved 10 and less out of the possible maximum of 60 scores in 95% of the participants of the study. It is concluded that the application of the COMQ-12 questionnaire helps to concentrate the attention of the medical specialists on the subjects whose health

    The Adult Carer Quality of Life questionnaire (AC-QoL) is a reliable and valid instrument used to assess the quality of life (QoL) of adult family caregivers. We explored the psychometric properties and tested the reliability and validity of a Chinese version of the AC-QoL with reliability and validity testing in 409 Chinese stroke caregivers. We used item-total correlation and extreme group comparison to do item analysis. To evaluate its reliability, we used a test-retest reliability approach, intraclass correlation coefficient (ICC), together with Cronbach’s alpha and model-based internal consistency index; to evaluate its validity, we used scale content validity, confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) via principal component analysis with varimax rotation. We found that the CFA did not in fact confirm the original factor model and our EFA yielded a 31-item measure with a five-factor model. In conclusions, although some items performed differently in our analysis of the original English language version and our Chinese language version, our translated AC-QoL is a reliable and valid tool which can be used to assess the quality of life of stroke caregivers in mainland China. Chinese version AC-QoL is a comprehensive and good measurement to understand caregivers and has the potential to be a screening tool to assess QoL of caregiver. PMID:29131845

    The short form of impact of weight on quality of life (IWQOL)-Lite is a 31-item, self-report, obesity-specific measure of health-related quality of life (HRQOL) that consists of a total score and scores on each of five scales--physical function, self-esteem, sexual life, public distress, and work--and that exhibits strong psychometric properties. This study was undertaken in order to assess test-retest reliability and discriminant validity in a heterogeneous sample of individuals not in treatment. Individuals were recruited from the community to complete questionnaires that included the IWQOL-Lite, SF-36, Rosenberg self-esteem (RSE) scale, Marlowe-Crowne social desirability scale, global ratings of quality of life, and sexual functioning and public distress ratings. Persons currently enrolled in weight loss programs or with a body mass index (BMI) of less than 18.5 were dropped from the analyses, leaving 341 females and 153 males for analysis, with an average BMI of 27.4. For test-retest reliability, 112 participants completed the IWQOL-Lite again. ANOVA revealed significant main effects for BMI for all IWQOL-Lite scales and total score. Females showed greater impairment than males on all scales except public distress. Internal consistency ranged from 0.816 to 0.944 for IWQOL-Lite scales and was 0.958 for total score. Test-retest reliability ranged from 0.814 to 0.877 for scales and was 0.937 for total score. Internal consistency and test-retest results for overweight/obese subjects were similar to those obtained for the total sample. There was strong evidence for convergent and discriminant validity of the IWQOL-Lite in overweight/obese subjects. As in previous studies conducted on treatment-seeking obese persons, the IWQOL-Lite appears to be a reliable and valid measure of obesity-specific quality of life in overweight/obese persons not seeking treatment.

    Objectives. To assess the validity, reliability, and responsiveness to change of a patient self-reported questionnaire combining the Widespread Pain Index and the Symptom Severity Score as well as construct outcome measures and comorbidities assessment in fibromyalgia patients. Methods. The PROMs-FM was conceptualized based on frameworks used by the WHO Quality of Life tool and the PROMIS. Initially, cognitive interviews were conducted to identify item pool of questions. Item selection and reduction were achieved based on patients as well as an interdisciplinary group of specialists. Rasch and internal consistency reliability analyses were implemented. The questionnaire included the modified ACR criteria main items (Symptom Severity Score and Widespread Pain Index), in addition to assessment of functional disability, quality of life (QoL), review of the systems, and comorbidities. Every patient completed HAQ and EQ-5D questionnaires. Results. A total of 146 fibromyalgia patients completed the questionnaire. The PROMs-FM questionnaire was reliable as demonstrated by a high standardized alpha (0.886–0.982). Content construct assessment of the functional disability and QoL revealed significant correlation (p < 0.01) with both HAQ and EQ-5D. Changes in functional disability and QoL showed significant (p < 0.01) variation with diseases activity status in response to therapy. There was higher prevalence of autonomic symptoms, CVS risk, sexual dysfunction, and falling. Conclusions. The developed PROMs-FM questionnaire is a reliable and valid instrument for assessment of fibromyalgia patients. A phased treatment regimen depending on the severity of FMS as well as preferences and comorbidities of the patient is the best approach to tailored patient management. PMID:27190648

    The objective of the present study was to evaluate the quality of general health information in Spanish language web pages, and the official Regional Services web pages from the different Autonomous Regions. It is a cross-sectional study. We have used a previously validated questionnaire to study the present state of the health information on Internet for a lay-user point of view. By mean of PageRank (Google®), we obtained a group of webs, including a total of 65 health web pages. We applied some exclusion criteria, and finally obtained a total of 36 webs. We also analyzed the official web pages from the different Health Services in Spain (19 webs), making a total of 54 health web pages. In the light of our data, we observed that, the quality of the general information health web pages was generally rather low, especially regarding the information quality. Not one page reached the maximum score (19 points). The mean score of the web pages was of 9.8±2.8. In conclusion, to avoid the problems arising from the lack of quality, health professionals should design advertising campaigns and other media to teach the lay-user how to evaluate the information quality.

    In recent years, the growth of population and increase of the industries around the tributaries of Yamchi Dam basin have led to deterioration of dam water quality. This study aimed to evaluate the quality of the Yamchi Dam basin water, which is used for drinking and irrigation consumptions using Canadian Water Quality Index (CWQI) model, and to determine the main water pollution sources of this basin. Initially, nine sampling stations were selected in the sensitive locations of the mentioned basin's tributaries, and 12 physico-chemical parameters and 2 biological parameters were measured. The CWQI for drinking consumptions was under 40 at all the stations indicating a poor water quality for drinking consumptions. On the other hand, the CWQI was 62-100 for irrigation at different stations; thus, the water had an excellent to fair quality for irrigation consumptions. Almost in all the stations, the quality of irrigation and drinking water in cold season was better. Besides, for drinking use, total coliform and fecal coliform had the highest frequency of failure, and total coliform had the maximum deviation from the specified objective. For irrigation use, total suspended solids had the highest frequency of failure and deviation from the objective in most of the stations. The pisciculture center, aquaculture center, and the Nir City wastewater discharge were determined as the main pollution sources of the Yamchi Dam basin. Therefore, to improve the water quality in this important surface water resource, urban and industrial wastewater treatment prior to disposal and more stringent environmental legislations are recommended.

    In the latest 2015 Quality of Death Index, Singapore managed to move SIX steps forward from 18 th to the 12 th position. This advancement has been hard-won, with victories to improve the level of palliative care such as creating awareness of palliative service, improving coordinated care and growing an adequate capacity to meet the demand of care in our fast -growing ageing population. But it hasn't always been easy. Despite being a first world country, Asian societies like Singapore have inherited taboos regarding public dialogue about death and dying. Such dialogue is traditionally avoided. However, through years of continual effort in improving the standard of palliative care delivery, redesigning education module, creating public awareness and improving funding system, Singapore's palliative care providers have improved the lives of those with life-limiting illnesses. Nevertheless, the government will continue to improve and work toward achieving single digits in the next ranking of the Quality of Death Index.

    The Canadian Diabetes Association recommends that people with diabetes choose foods with low-glycemic index (GI). This study developed a questionnaire measuring Theory of Planned Behaviour (TPB) constructs relative to consuming a low-GI diet by people with diabetes so as to achieve a better understanding of which TPB constructs, demographic characteristics and diabetes-related variables best predict intention to consume a low-GI diet. A questionnaire to measure intentions to consume a low-GI diet was developed based on TPB constructs and was administered to 369 adults (30 to 75 years) with type 1 or type 2 diabetes. Responses were analyzed using multiple linear regression. More than 90% of participants (mean age, 56.5±10.8 years; mean body mass index, 30.5±7.2 kg/m(2)) cited reduction and maintenance of healthy blood glucose levels as an advantage of eating low-GI foods. Older age, higher income, female gender, having type 2 diabetes, diabetes treatment (diet only) and understanding of the GI were positively associated with intention to eat a low-GI diet. TPB constructs that significantly predicted intentions to eat a low-GI diet were instrumental attitude (beta = 0.24, p<0.001); subjective norms (beta = 0.13, p=0.007); and perceived behavioural control (beta = 0.55, p<0.001). This new questionnaire is a valid tool to assess TPB constructs contributing to intentions to eat a low-GI diet by people with diabetes. Future studies that use this questionnaire can shed light on how TPB concepts in clinical practice can help people with diabetes to change their dietary intake.

    Cerebellar ataxia comprises a group of debilitating diseases that are the result of progressive cerebellar degeneration. Recent studies suggest that, like other neurodegenerative diseases, sleep impairments are common in cerebellar ataxia. In light of the role of sleep in mood regulation and cognition, we sought to assess interactions between sleep, cognition, and affect in individuals with cerebellar ataxia. A survey of 176 individuals with cerebellar ataxia was conducted. The battery of instruments included a modified International Cooperative Ataxia Rating Scale, Pittsburgh Sleep Quality Index, Restless Leg Syndrome Questionnaire, REM Behavior Disorder Questionnaire, Beck Depression Inventory, Epworth Sleepiness Scale, and a Composite Cognitive Questionnaire. Fifty-one percent of individuals indicated significant sleep disturbances on the Pittsburgh Sleep Quality Index, 73% of participants had two or more symptoms of restless leg syndrome, and 88% had two or more symptoms of REM behavior disorder. Ataxia severity, based on the modified International Cooperative Ataxia Rating Scale, predicted scores on the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale and REM Behavior Disorder Questionnaire. Median split analyses revealed that cognitive function appeared to be reduced and depressive symptoms were greater for those individuals with poor subjective sleep quality and severe RLS. Importantly, sleep appears to play a mediatory role between disease severity and depressive symptoms. These results suggest that disturbed sleep may have detrimental effects on cognition and affect in individuals with cerebellar ataxia. While objective measures are needed, such results suggest that treating sleep deficits in these individuals may improve cognitive and mental health as well as overall quality of life.

    The Paediatric Quality of Life Inventory (PedsQL™) questionnaire is a widely used, generic instrument designed for measuring health-related quality of life (HRQoL); however, it is not preference-based and therefore not suitable for cost-utility analysis. The Child Health Utility Index-9 Dimension (CHU-9D), however, is a preference-based instrument that has been primarily developed to support cost-utility analysis. This paper presents a method for estimating CHU-9D index scores from responses to the PedsQL™ using data from a randomised controlled trial of prednisolone therapy for treatment of childhood corticosteroid-sensitive nephrotic syndrome. HRQoL data were collected from children at randomisation, week 16, and months 12, 18, 24, 36 and 48. Observations on children aged 5 years and older were pooled across all data collection timepoints and were then randomised into an estimation (n = 279) and validation (n = 284) sample. A number of models were developed using the estimation data before internal validation. The best model was chosen using multi-stage selection criteria. Most of the models developed accurately predicted the CHU-9D mean index score. The best performing model was a generalised linear model (mean absolute error = 0.0408; mean square error = 0.0035). The proportion of index scores deviating from the observed scores by <  0.03 was 53%. The mapping algorithm provides an empirical tool for estimating CHU-9D index scores and for conducting cost-utility analyses within clinical studies that have only collected PedsQL™ data. It is valid for children aged 5 years or older. Caution should be exercised when using this with children younger than 5 years, older adolescents (>  13 years) or patient groups with particularly poor quality of life. 16645249.

    "Vespid Allergy Quality of Life Questionnaire (VQLQ)" has been used to assess psychological burden of disease. The aim of this study was to evaluate validity, reliability and responsiveness to interventions of the Turkish version. The Turkish language Questionnaire (VQLQ-T) was administered to 81 patients with bee allergy and 65 patients with vespid allergy from different groups to achieve cross-sectional validation. To establish longitudinal validity, the questionnaire was administered to 36 patients treated with venom immunotherapy. The cross-sectional validation in patients with vespid venom allergy showed a correlation coefficient of 0.97 (Cronbach α). Spearman's correlation coefficient of the pretreatment VQLQ-T score with Expectation of Outcome (EoO) questionnaire score was 0.55 (p < 0.001). After treatment, correlation between VQLQ-T score and EoO score was 0.64 (p = 0.003) in these patients. The cross-sectional instrument validation for non-beekeepers with bee venom allergy yielded a correlation coefficient of 0.96 (Cronbach α). Spearman's correlation coefficient between pretreatment VQLQ-T score and EoO score was 0.47 (p < 0.001) and after treatment, correlation between VQLQ-T score and EoO score was 0.78 (p = 0.008) in these patients. These findings indicate cross-sectional validity of VQLQ-T. In the longitudinal validation, there was a positive correlation between EoO and VQLQ-T with a correlation coefficient of 0.562 (p < 0.001). While mean (±SD) VQLQ-T score was 5.27 (±1.29) in pretreatment, it was 2.78 (±1.01) after treatment (p < 0.001). The correlation between the mean change in VQLQ-T score and the mean change in EoO score was 0.42 (p = 0.011). The Turkish version of VQLQ-T enables measurement of Quality of Life (QoL) in patients with either vespid or bee venom allergy. Furthermore, responsiveness of this instrument demonstrates the questionnaire's ability to detect changes over time.

    To produce a cross-culturally adapted and validated Turkish version of The Core Outcome Measure Index (COMI) Back questionnaire. Ninety-six Turkish-speaking patients with non-specific low back pain (LBP) were recruited from orthopedic and physical therapy outpatient clinics in a public hospital. They completed a booklet of questionnaires containing Turkish version of COMI, adjectival pain scale, Roland Morris disability questionnaire, European 5 Dimension Questionnaire and brief version of World Health Organization Quality of Life Questionnaire. Within following 7-14 days, 67 patients, reported no or minimal changes in their back pain status, completed the Turkish COMI again to assess reproducibility. Data quality was good with very few missing answers. COMI summary index score displayed 3% floor effects and no ceiling effects. The correlations between the COMI summary index score and each of the full instrument whole scores were found to be excellent to very good (ρ = - 0.81 to 0.74). Reliability expressed as intraclass correlation coefficient (ICC) was 0.95 (95% CI 0.91-0.97). Standard error of measurement (SEM agreement ) was acceptable at 0.41 and the minimum detectable change (MDC 95% ) was 1.14. Turkish version of the COMI has acceptable psychometric properties. It is a valid and reliable instrument and cross-culturally adapted, in accordance with established guidelines, for the use by Turkish-speaking patients. It can be recommended for use in evaluation of patients with chronic LBP in daily practice, in international multicenter studies and in spine registry systems.

    The clinical relevance of Health-Related Quality of Life (HRQoL) in meningioma patients has been increasingly acknowledged in recent years. Various questionnaires have been used. However, almost none of these questionnaires has been particularly developed for and/or validated in this patient group. Therefore, the aim of this study was to assess the relevance and comprehensiveness of existing HRQoL questionnaires used in meningioma research and to assess the agreement between patients and health care professionals (HCPs) on the most relevant and important HRQoL issues. A systematic literature search, following the PRISMA statement, was conducted to identify all HRQoL questionnaires used in meningioma research. Semi-structured interviews were organized with patients and HCPs to (1) assess the relevance of all issues covered by the questionnaires (score 0-3: not relevant-highly relevant), (2) assess the ten most important issues, and (3) identify new relevant HRQoL issues. Fourteen different questionnaires were found in the literature, comprising 140 unique issues. Interviews were conducted with 20 patients (median age 57, 71% female) and 10 HCPs (4 neurosurgeons, 2 neurologists, 2 radiotherapists, 1 rehabilitation specialist, 1 neuropsychologist; median experience 13 years). Meningioma patients rated 17-80% of the issues in each of the questionnaires as relevant, HCPs 90-100%. Patients and HCPs agreed on the relevance of only 49 issues (35%, Cohen's kappa: 0.027). Both patients and HCPs considered lack of energy the most important issue. Patients and HCPs suggested five additional relevant issues not covered by current HRQoL questionnaires. Existing HRQoL questionnaires currently used in meningioma patients do not fully cover all relevant issues to these patients. Agreement between patients and HCPs on the relevance of issues was poor. Both findings support the need to develop and validate a meningioma-specific HRQoL questionnaire.

    Irritable Bowel Syndrome (IBS) is one of the most common gastrointestinal disorders particularly affecting the quality of life (QOL). Evaluating QOL in IBS patients is a valuable method of defining a psychobiological pattern of disease. Various disease specific and general instruments are now available to measure health-related QOL (HRQOL) in IBS patients. Though, no comparison has been made between these tools especially in non-western countries. We aimed to compare QOL measures between two specific and general QOL questionnaires in a sample of Iranian IBS patients. A total of 250 IBS patients were diagnosed based on Rome III criteria (mean age 29.6 ± 9.6 years). HRQOL was assessed using disease specific quality of life for IBS (IBS-QOL) and generic World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaires. Patients also completed Speilberger`s "State/Trait Anxiety Inventory" and "Beck Depression Inventory-II" for the evaluation of anxiety and depression symptoms. The severity of symptoms was independently associated with HRQOL in patients using WHOQOL-BREF and IBS-QOL (r = -0.48 and -0.39 respectively, P < 0.001). In linear regression analysis, a strong correlation was observed between the HRQOL scores of IBS-QOL and the WHOQOL-BREF questionnaires (standard β = 0.86 (95%CI: 1.15 - 1.44), P value < 0.001). Controlling for anxiety and depression symptoms did not influence the strength of observed correlation. The WHOQOL-BREF is a psychometrically sound, rapid and convenient instrument whose HRQOL measure is as valid and accurate as the disease-specific IBS-QOL questionnaire. It seems reasonable to use the WHOQOL-BREF alongside the IBS-QOL.

    To develop an instrument to measure subjective quality of vision: the Quality of Vision (QoV) questionnaire. A 30-item instrument was designed with 10 symptoms rated in each of three scales (frequency, severity, and bothersome). The QoV was completed by 900 subjects in groups of spectacle wearers, contact lens wearers, and those having had laser refractive surgery, intraocular refractive surgery, or eye disease and investigated with Rasch analysis and traditional statistics. Validity and reliability were assessed by Rasch fit statistics, principal components analysis (PCA), person separation, differential item functioning (DIF), item targeting, construct validity (correlation with visual acuity, contrast sensitivity, total root mean square [RMS] higher order aberrations [HOA]), and test-retest reliability (two-way random intraclass correlation coefficients [ICC] and 95% repeatability coefficients [R(c)]). Rasch analysis demonstrated good precision, reliability, and internal consistency for all three scales (mean square infit and outfit within 0.81-1.27; PCA >60% variance explained by the principal component; person separation 2.08, 2.10, and 2.01 respectively; and minimal DIF). Construct validity was indicated by strong correlations with visual acuity, contrast sensitivity and RMS HOA. Test-retest reliability was evidenced by a minimum ICC of 0.867 and a minimum 95% R(c) of 1.55 units. The QoV Questionnaire consists of a Rasch-tested, linear-scaled, 30-item instrument on three scales providing a QoV score in terms of symptom frequency, severity, and bothersome. It is suitable for measuring QoV in patients with all types of refractive correction, eye surgery, and eye disease that cause QoV problems.

    The school canteen provides a substantial proportion of the daily nutritional intake for many children. There are nutritional standards for school meals, however, it is still difficult to assess the dietary quality. To design a questionnaire for assessing the dietary quality of school meals, quickly and easily. A dietary questionnaire (COMES) was designed on the basis of the current recommendations. COMES consist of 15 items related to the food-frequency and to other characteristics of school meals. Then, a longitudinal prospective study was performed in order to analyze, with COMES, 36 school meals of 4 catering companies from Castilla y León during the academic years 2006-2007 to 2010-2011. Differences in dietary quality menus according to the management system of catering companies (in situ vs. transported) were analyzed by using the Mann-Whitney and the Kruskal-Wallis tests. The significance was reached at p <0,05. The frequency intake of meat, dairy and prepared products was higher to the recommended in 97,2%, 94,4% and 27,8% of the analyzed menus, respectively. By contrast, the frequency intake of fish, fruit, legume, and vegetable garnishes were lower to the recommended in 83,3%, 94,4%, 91,7% and 75% of menus, respectively. Nevertheless, recommendations established by our consensus document for school meals are complied for all food groups, except for dairy and fruits. The variety of foods and culinary techniques were appropriate. No significant differences were found in the COMES score according to the management system (p=0,87), although catering system provides higher dietary quality. A new tool to assess quickly and easily the nutritional quality of school meals has been proposed. The assessment of the frequency intake of the most problematic foods for schoolchildren with this scale is much more demanding than the current recommendations. Even so, menus analyzed showed an acceptable quality in terms of variety of foods and culinary techniques, although

    The purpose was to investigate how physical function is assessed in people with musculoskeletal disorders (MSD) in the neck. Specifically, we aimed to determine: (1) Which questionnaires are used to assess physical function in people with MSD in the neck? (2) What do those questionnaires measure? (3) What are the measurement properties of the questionnaires? A systematic review was performed to identify questionnaires and psychometric evaluations. The content of the questionnaires was categorized according to the International Classification of Function, Disability and Health, and the psychometric properties were quality-rated using the COnsensus-based Standards for the selection of health Measurement INstruments checklist. Ten questionnaires and 32 articles evaluating measurement properties were analyzed. Most questionnaires covered only the components body functions and activity and participation, more often activity participation than body function. Internal consistency was adequate in most questionnaires, whereas responsiveness was generally low. Neck Disability Index was most evaluated, but the evaluations of all questionnaires tended to cover most properties in the checklist. The questionnaires differed substantially in items and extent to which their psychometric properties had been evaluated. Focus of measurement was on activities in daily life rather than physical function as such. Implications for Rehabilitation To provide early diagnostics and effective treatment for patients with neck disorders, valid and reliable instruments that measure relevant aspects of the disorders are needed. This paper presents an overview of content and quality of questionnaires used to assess physical function in neck disorders, which may facilitate informed decisions about which measurement instruments to use when evaluating the course of neck disorders. Most of the questionnaires need more testing to judge the quality, however the NDI was the most frequently tested

To evaluate the quality of life in patients with CVID using the questionnaire SF -36. A descriptive cross-sectional survey included 23 patients diagnosed with CVID, belonging to the Immunodeficiency Clinic Service of Allergology and Clinical Immunology in CMN Siglo XXI, IMSS. The questionnaire SF- 36 validated in Spanish was applied. descriptive statistics with simple frequencies and percentages, inferential statistics: Fisher exact test and ANOVA to compare means. The study involved 23 patients, 14 women (60%) and 9 men (40%), mean age 38.6 ± 14.7 years. The highest score was obtained in 83% emotional role. Dimensions with further deterioration in both genders were: 54% general health, vitality 59% and physical performance 72%. No differences were found regarding gender. The only issue in which statistically significant differences were found in patients with more than 3 comorbidities was change in health status in the past year (p=0.007). Patients with severe comorbidities, such as haematologicaloncological (leukemias, lymphomas, neoplasms), and pulmonary (severe bronchiectasis) showed further deterioration in the aspects of physical performance 73% and 64% emotional role. 65% of patients reported an improvement in health status in 74% in the last year. Adult patients with CVID show deterioration in different dimensions, particularly in the areas of general health, vitality and physical performance. Patients with severe comorbidities such as leukemia, lymphomas, malignancies and severe bronchiectasis show further deterioration in some aspects of quality of life, especially in physical performance and emotional role.

    2014-01-01

    Background A more comprehensive estimate of environmental quality would improve our understanding of the relationship between environmental conditions and human health. An environmental quality index (EQI) for all counties in the U.S. was developed. Methods The EQI was developed in four parts: domain identification; data source acquisition; variable construction; and data reduction. Five environmental domains (air, water, land, built and sociodemographic) were recognized. Within each domain, data sources were identified; each was temporally (years 2000–2005) and geographically (county) restricted. Variables were constructed for each domain and assessed for missingness, collinearity, and normality. Domain-specific data reduction was accomplished using principal components analysis (PCA), resulting in domain-specific indices. Domain-specific indices were then combined into an overall EQI using PCA. In each PCA procedure, the first principal component was retained. Both domain-specific indices and overall EQI were stratified by four rural–urban continuum codes (RUCC). Higher values for each index were set to correspond to areas with poorer environmental quality. Results Concentrations of included variables differed across rural–urban strata, as did within-domain variable loadings, and domain index loadings for the EQI. In general, higher values of the air and sociodemographic indices were found in the more metropolitan areas and the most thinly populated areas have the lowest values of each of the domain indices. The less-urbanized counties (RUCC 3) demonstrated the greatest heterogeneity and range of EQI scores (−4.76, 3.57) while the thinly populated strata (RUCC 4) contained counties with the most positive scores (EQI score ranges from −5.86, 2.52). Conclusion The EQI holds promise for improving our characterization of the overall environment for public health. The EQI describes the non-residential ambient county-level conditions to which residents are

    To develop and test a user-friendly questionnaire for rapidly assessing quality of life (QOL) in thyroid eye disease (TED). A three-item questionnaire, the TED-QOL, was designed and compared to the 16-item Graves Ophthalmopathy (GO)-QOL and the nine-item GO-Quality of Life Scale (QLS). 100 patients with TED were administered all three questionnaires on two occasions. Results were compared to clinical severity scores (Vision, Inflammation, Strabismus, Appearance (VISA) classification). Main outcomes were construct and criterion validity, test-retest reliability, duration, comprehension and completion rates. TED-QOL correlated strongly with the other questionnaires for corresponding items (Pearson correlation: appearance 0.71, 0.62; functioning 0.69, 0.66; overall QOL 0.53). Test-retest analysis demonstrated good reliability for all three questionnaires (intraclass correlations: TED-QOL 0.81, 0.74, 0.87; GO-QOL 0.81, 0.82; GO-QLS 0.74, 0.86, 0.67). TED-QOL was significantly faster to complete (1.6 min vs GO-QOL 3.1 min, GO-QLS 2.7 min, p<0.0001) and had a higher completion rate (100% vs GO-QOL 78%, GO-QLS 94%). There was only moderate correlation between items on all three questionnaires and VISA scores. The TED-QOL is rapid and easy to complete and analyse and has similar validity and reliability to longer questionnaires. All questionnaires showed only moderate correlation with disease severity, emphasising the discrepancy between objective and subjective assessments and the importance of measuring both.

    AIMS The aims were to develop and validate a new Prescription Quality Index (PQI) for the measurement of prescription quality in chronic diseases. METHODS The PQI were developed and validated based on three separate surveys and one pilot study. Criteria were developed based on literature search, discussions and brainstorming sessions. Validity of the criteria was examined using modified Delphi method. Pre-testing was performed on 30 patients suffering from chronic diseases. The modified version was then subjected to reviews by pharmacists and clinicians in two separate surveys. The rater-based PQI with 22 criteria was then piloted in 120 patients with chronic illnesses. Results were analysed using SPSS version 12.0.1 RESULTS Exploratory principal components analysis revealed multiple factors contributing to prescription quality. Cronbach's α for the entire 22 criteria was 0.60. The average intra-rater and inter-rater reliability showed good to moderate stability (intraclass correlation coefficient 0.76 and 0.52, respectively). The PQI was significantly and negatively correlated with age (correlation coefficient −0.34, P < 0.001), number of drugs in prescriptions (correlation coefficient −0.51, P < 0.001) and number of chronic diseases/conditions (correlation coefficient −0.35, P < 0.001). CONCLUSIONS The PQI is a promising new instrument for measuring prescription quality. It has been shown that the PQI is a valid, reliable and responsive tool to measure quality of prescription in chronic diseases. PMID:20840442

    This paper reports a study to test validity and internal consistency of the audit diabetes-dependent quality of life questionnaire in the Slovak population and to evaluate its usefulness in the context of education of people with diabetes. The individualised instruments designed to measure individuals' perceptions of the impact of diabetes on their quality of life may be helpful to identify individuals' preferences, motivational deficits in diabetes management and to tailor individual treatment strategies. Survey. After linguistic validation, the structure of the questionnaire was tested using factor analysis on 104 patients who were recruited from the National Institute of Endocrinology and Diabetology in Lubochna. Internal consistency was evaluated by computing Cronbach's alpha. Clinical variables related to the quality of life were analysed using one-way ANOVA, multifactor ANOVA, Pearson's and Spearman's rank correlation coefficients. A one-dimensional scale structure was supported and internal consistency was high (alpha = 0.93). Variance in impact of diabetes on quality of life was explained by age, presence of late complications and type of insulin regimen. The audit diabetes-dependent quality of life is culturally appropriate, valid and reliable in the sample of Slovak patients attending the educational programme. Our results agreed with previous European and Asian studies supporting its usefulness in the context of diabetes self-management education. Individualised diabetes-specific quality of life measures allow better understanding of patients' treatment preferences and, consequently, more effective prioritizing and targeting of appropriate educational interventions. This instrument may be useful in routine clinical practice and as an outcome measure for international clinical research trials evaluating effectiveness of educational programmes.

    Quality of life (QoL) is still assessed using paper-based and fixed-length questionnaires, which is one reason why QoL measurements have not been routinely implemented in clinical practice. Providing new QoL measures that combine computer technology with modern measurement theory may enhance their clinical use. The aim of this study was to develop a QoL multidimensional computerized adaptive test (MCAT), the SQoL-MCAT, from the fixed-length SQoL questionnaire for patients with schizophrenia. In this multicentre cross-sectional study, we collected sociodemographic information, clinical characteristics (i.e., duration of illness, the PANSS, and the Calgary Depression Scale), and quality of life (i.e., SQoL). The development of the SQoL-CAT was divided into three stages: (1) multidimensional item response theory (MIRT) analysis, (2) multidimensional computerized adaptive test (MCAT) simulations with analyses of accuracy and precision, and (3) external validity. Five hundred and seventeen patients participated in this study. The MIRT analysis found that all items displayed good fit with the multidimensional graded response model, with satisfactory reliability for each dimension. The SQoL-MCAT was 39% shorter than the fixed-length SQoL questionnaire and had satisfactory accuracy (levels of correlation >0.9) and precision (standard error of measurement <0.55 and root mean square error <0.3). External validity was confirmed via correlations between the SQoL-MCAT dimension scores and symptomatology scores. The SQoL-MCAT is the first computerized adaptive QoL questionnaire for patients with schizophrenia. Tailored for patient characteristics and significantly shorter than the paper-based version, the SQoL-MCAT may improve the feasibility of assessing QoL in clinical practice.

    The aim of our study was to investigate the quality of life of patients undergoing cleft lip or cleft lip and palate as well as the perception of quality of life of patients perceived by their parents slot. Fifty-one adolescents and young adults (29 boys and 22 girls) who underwent cleft lip (FL 22) or lip and palate (CLP 29) and their parents have received psychological and surgical joint consultation. The minimum age for inclusion was 10 years (mean age 15.5 years). A quality of life questionnaire (VSP-A) "children" was given between 10 and 11 years and a questionnaire "adolescents" beyond. Parents have them answered a questionnaire of perceived quality of life of their children. The results were analyzed and compared to a control population (Statistics Student test). Perceived parents lived in relation to their children was obtained through the study of linear regression curves. The response rate to the questionnaires was 66.7% for parents, 85.7% for children and 63.6% for teenagers. The quality of life of the patients was assessed by the patients to 65.1/100 on average. The index of overall quality of life was superimposed on the control population (p=0.66). Perceived quality of life of patients by their parents was fairly close to the quality of life described by patients (66.5). On the areas of family, education, recreation, quality index was proportionately less than for other areas. For each of these areas, parents overestimated the quality of life of their child. Compared to the control group the fields of education, leisure, vitality quality index were significantly lower in the/FL population P. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    The aim of the SINERGE study was to assess the impact of nocturnal heartburn on quality of life, sleep, and productivity. Ambulatory patients >/=18 years old and classified as defined cases of nocturnal heartburn (n=337), nonnocturnal heartburn (n=139), uncontrolled hypertension (n=198), and symptomatic depression (n=104) were included in this cross-sectional study. Information on age, gender, body mass index, and comorbidity was collected and the following validated questionnaires were applied: SF-12, Pittsburgh Sleep Quality Index, and Work Productivity and Activity Impairment questionnaire. The prevalence of primary care consultation for heartburn and nocturnal heartburn was 4.7% and 1.9%, respectively. Health-related quality of life, sleep, and productivity were significantly impaired in patients with frequent nocturnal heartburn symptoms as compared with those of the patients without nocturnal symptoms or patients with hypertension. Nocturnal heartburn poses a considerable burden for the sufferer because of the impact on quality of life, sleep, and daily activities.

    Over the past decades, the number of childhood obesity cases has increased significantly, which led to an increase in the number of adults suffering from degenerative diseases such as diabetes mellitus (DM). Glucomannan-Enriched Soy Milk Ice Cream (GSMIC) may prevent obesity in children. The aim of the study was to test the level of carbohydrates, protein, fat, dietary fiber, glycemic index, glycemic load, and organoleptic quality of GSMIC. This experiment used a completely randomized design to test three formulations of glucomannan flour and soy milk (0.5%, 1.5%, and 2.5%). The products were tested for nutritional composition, and evaluated on glycemic index, glycemic load, and organoleptic quality. GSMIC 2.5% had higher levels of dietary fiber and high carbohydrate, protein, and fat content compared to ice cream (3.99%, 30.7%, 1.50%, 1.33%, respectively). The glycemic index of ice cream and 2.5% GSMIC were 75.83 (75%) and 51.48 (51%), respectively, while the glycemic load of ice cream and 2.5% GSMIC were 9.04 and 11.61, respectively. Based on the organoleptic analysis, formulation preferred by the panellists was 2.5% glucomannan flour. Glucomannan flour affected the level of carbohydrates, protein, fat, dietary fiber, glycemic index, glycemic load, and organoleptic quality in soy milk ice cream.

    Purpose To examine the congruence between polysomnography obstructive apnea hypopnea index (OAHI) and parent reported obstructive sleep apnea (OSA) symptoms in 6-to-11 year-old children with juvenile idiopathic arthritis (JIA) and controls; and to compare fatigue and quality of life in JIA and control children based on OAHI and OSA symptoms. Methods Sixty-eight children with JIA and 75 controls and a parent participated. Children underwent one night of polysomnography in a sleep laboratory. Parents completed the sleep-related breathing disorders scale - Pediatric Sleep Questionnaire (PSQ), and both children and parents completed the Pediatric Quality of Life Generic Core Scale and the Multidimensional Fatigue scale. Results In JIA, 86% who met the OAHI clinical criteria for OSA (≥ 1.5) were above the PSQ OSA symptom cut-off score with a sensitivity of 0.86 and a specificity of 0.28. In the control group, 63% who met the OAHI clinical criteria for OSA, were above the PSQ OSA symptom cut-off score, with a sensitivity of 0.63 and a specificity of 0.42. All children above both the clinical criteria for OAHI and OSA symptom cut-off score had the most impaired quality of life and greater fatigue compared to those below both the clinical criteria for OAHI and the OSA symptom cut-off score. Conclusion Children who meet clinical criteria for OSA and also scored high on a parent reported screening tool for OSA symptoms had the most impaired quality of life and more fatigue. The PSQ has potential to identify children at risk for OSA. PMID:27987106

    The aim of this study was to adapt the Australian Quality of Life in Childhood Epilepsy Questionnaire (QOLCE) and determine its psychometric properties in a North American population. Participants were North American families with children diagnosed with epilepsy. Parents were asked to complete the American QOLCE (USQOLCE) and the Child Health Questionnaire (CHQ). Seventy-one families completed the USQOLCE. The internal consistency reliability of the subscales was good. USQOLCE subscales correlated highly with theoretically similar subscales contained in the CHQ. Theoretically dissimilar subscales on the two instruments did not correlate as well. USQOLCE correlated significantly with a parental rating of seizure severity and an independent measure of degree of postoperative seizure control. This study demonstrated that the USQOLCE is suitable for a North American population with evidence of its reliability and validity including its sensitivity to seizure burden.

    Chronic obstructive pulmonary disease (COPD) is increasingly recognized as a multicomponent disease with systemic consequences and effects on quality of life. Single measures such as lung function provide a limited reflection of how the disease affects patients. Composite measures have the potential to account for many of the facets of COPD. To derive and validate a multicomponent assessment tool of COPD severity that is applicable to all patients and health care settings. The index was derived using data from 375 patients with COPD in primary care. Regression analysis led to a model explaining 48% of the variance in health status as measured by the Clinical COPD Questionnaire with four components: dyspnea (D), airflow obstruction (O), smoking status (S), and exacerbation frequency (E). The DOSE Index was validated in cross-sectional and longitudinal samples in various health care settings in Holland, Japan, and the United Kingdom. The DOSE Index correlated with health status in all data sets. A high DOSE Index score (> or = 4) was associated with a greater risk of hospital admission (odds ratio, 8.3 [4.1-17]) or respiratory failure (odds ratio, 7.8 [3.4-18.3]). The index predicted exacerbations in the subsequent year (P < or = 0.014). The DOSE Index is a simple, valid tool for assessing the severity of COPD. The index is related to a range of clinically important outcomes such as health care consumption and predicts future events.

    Patient-reported outcomes are becoming increasingly important when investigating results of patient and disease management. In sacral tumor, the symptoms of patients can vary substantially; therefore, no single questionnaire can adequately account for the full spectrum of symptoms and disability. The purpose of this study is to analyze redundancy within the current sacral tumor survey and make a recommendation for an updated version based on the results and patient and expert opinions. A survey study from a tertiary care orthopedic oncology referral center was used. The patient sample included 70 patients with sacral tumors (78% chordoma). The following 10 questionnaires included in the current sacral tumor survey were evaluated: the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Item short form, PROMIS Pain Intensity short form, PROMIS Pain Interference short form, PROMIS Neuro-QOL v1.0 Lower Extremity Function short form, PROMIS v1.0 Anxiety short form, the PROMIS v1.0 Depression short form, the International Continence Society Male short form, the Modified Obstruction-Defecation Syndrome questionnaire, the PROMIS Sexual Function Profile v1.0, and the Stoma Quality of Life tool. We performed an exploratory factor analysis to calculate the possible underlying latent traits. Spearman rank correlation coefficients were used to measure to what extent the questionnaires converged. We hypothesized the existence of six domains based on current literature: mental health, physical health, pain, gastrointestinal symptoms, sexual function, and urinary incontinence. To assess content validity, we surveyed 32 patients, 9 orthopedic oncologists, 1 medical oncologist, 1 radiation oncologist, and 1 orthopedic oncology nurse practitioner with experience in treating sacral tumor patients on the relevance of the domains. Reliability as measured by Cronbach alpha ranged from 0.65 to 0.96. Coverage measured by floor and ceiling effects ranged from 0% to 52

    Sexual dysfunction is a common experience in women with fibromyalgia. However, the physiopathology of this association is unclear. We aimed to evaluate whether sleep disturbance has an influence on sexual function in women with fibromyalgia. Fifty-four sexually active premenopausal women with fibromyalgia were enrolled in the study. The following questionnaires were used: the Female Sexual Function Index (FSFI), the Pittsburgh Sleep Quality Index (PSQI), the Fibromyalgia Impact Questionnaire (FIQ) and the Beck Depression Inventory (BDI). Appropriate statistical analyses were used by using SPSS 18. The mean FSFI score was 25.344 ± 6.52 and showed no correlation with age, body mass index, BDI or duration of fibromyalgia. However, a positive correlation between sexual dysfunction and low sleep quality was found (r=0.43; P=0.001). In addition, the median FSFI score was 29.2 (27.2-32.4) in patients with higher sleep quality (PSQI⩽5), whereas it was 21.4 (18.9-25.3) in patients with lower sleep quality (PSQI>5) (P<0.001). There was a positive correlation between sexual dysfunction and symptoms of fibromyalgia as indicated by a higher FIQ score (r=0.37; P=0.006). Sexual dysfunction in female patients with fibromyalgia may be due to low sleep quality. Treatment of the sleep disorder may improve female sexual function.

    New methods, based on soil microarthropods for soil quality evaluation have been proposed by some Authors. Soil microarthropods demonstrated to respond sensitively to land management practices and to be correlated with beneficial soil functions. QBS Index (QBS-ar) is calculated on the basis of microarthropod groups present in a soil sample. Each biological form found in the sample receives a score from 1 to 20 (eco-morphological index, EMI), according to its adaptation to soil environment. The objective of this study was to evaluate the effect of various rotation systems and sampling periods on soil biological quality index, in paddy soils. For the purpose of this study surface soil samples (0-15 cm depth) were collected from different rotation systems (rice-rice-rice, soya-rice-rice, fallow-rice and pea-soya-rice) with three replications, and four sampling times in April (after field preparation), June (after seedling), August (after tillering stage) and October (after rice harvesting). The study area is located in paddy soils of Verona area, Northern Italy. Soil microarthropods from a total of 48 samples were extracted and classified according to the Biological Quality of Soil Index (QBS-ar) method. In addition soil moisture, Cumulative Soil Respiration and pH were measured in each site. More diversity of microarthropod groups was found in June and August sampling times. T-test results between different rotations did not show significant differences while the mean difference between rotation and different sampling times is statistically different. The highest QBS-ar value was found in the fallow-rice rotation in the forth soil sampling time. Similar value was found in soya-rice-rice rotation. Result of linear regression analysis indicated that there is significant correlation between QBS-ar values and Cumulative Soil Respiration.

To validate the English SarQoL®, we assessed its validity (discriminative power, construct validity), reliability (internal consistency, test-retest reliability) and floor/ceiling effects. the SarQoL® questionnaire was translated without any major difficulties. Results indicated a good discriminative power (lower score of quality of life for sarcopenic subjects, P = 0.01), high internal consistency (Cronbach's alpha of 0.88), consistent construct validity (high correlations found with domains related to mobility, usual activities, vitality, physical function and low correlations with domains related to anxiety, self-care, mental health and social problems) and excellent test-retest reliability (intraclass coefficient correlation of 0.95, 95%CI 0.92-0.97). Moreover, no floor/ceiling has been found. a valid SarQoL® English questionnaire is now available and can be used with confidence to better assess the disease burden associated with sarcopenia. It could also be used as a treatment outcome indicator in research. © The Author 2016. Published by Oxford University Press on behalf of the British Geriatrics Society.

    To explore young women's health-related quality of life (HRQOL) and investigate whether menstrual and menarche experiences and objectification predict mental and physical health components of HRQOL. Menstruation plays a fundamental role in female biology, in women's relationship to their bodies and consequently in women's health and their HRQOL. Cross-sectional explorative survey design. A questionnaire that included the SF-36v2, the Self-objectification Questionnaire (SOQ), the Body Surveillance and Body Shame subscales of the Objectified Body Consciousness Scale, the Belief and Attitudes Towards Menstruation Questionnaire (four subscales), and questions on menarche and menstruation was administered at the end of 2013 to 319 Icelandic women who represented the population by age. The SF-36v2 includes eight dimensions addressing the mental and physical components of HRQOL. Scores are presented as raw data scores and scores based on standardised score of American women and range from 0 to 100 with higher scores indicating better HRQL. A hierarchical multiple linear regression model was employed to calculate significant predictors of mental and physical health components of HRQOL. Mean raw data scores on SF36-v2 dimensions ranged from 54.7 to 91.5. The participants scored below the standardised, mean norm-based score for all dimensions. Secrecy of menstruation, experience of body shame and pain during menstruation predicted worse mental HRQOL. To believe in the proscriptive role and the unpleasantness of menstruation, experience of body shame, medication for menstrual pain and not holding a university education predicted worse physical HRQOL. These two models explained 30% and 22% of the variance of the mental and physical components of SF36-v2, respectively. Young women's mental and physical HRQOL is influenced by the specific context of their lives. Women's health education should take into account the various relationships women may have with their bodies. © 2017

    A review has been made to understand the hydrogeochemical behaviour of groundwater through statistical analysis of long term water quality data (year 2005-2013). Water Quality Index ( WQI), descriptive statistics, Hurst exponent, fractal dimension and predictability index were estimated for each water parameter. WQI results showed that majority of samples fall in moderate category during 2005-2013, but monitoring site four falls under severe category (water unfit for domestic use). Brownian time series behaviour (a true random walk nature) exists between calcium (Ca^{2+}) and electric conductivity (EC); magnesium (Mg^{2+}) with EC; sodium (Na+) with EC; sulphate (SO4^{2-}) with EC; total dissolved solids (TDS) with chloride (Cl-) during pre- (2005-2013) and post- (2006-2013) monsoon season. These parameters have a closer value of Hurst exponent ( H) with Brownian time series behaviour condition (H=0.5). The result of times series analysis of water quality data shows a persistent behaviour (a positive autocorrelation) that has played a role between Cl- and Mg^{2+}, Cl- and Ca^{2+}, TDS and Na+, TDS and SO4^{2-}, TDS and Ca^{2+} in pre- and post-monsoon time series because of the higher value of H (>1). Whereas an anti-persistent behaviour (or negative autocorrelation) was found between Cl- and EC, TDS and EC during pre- and post-monsoon due to low value of H. The work outline shows that the groundwater of few areas needs treatment before direct consumption, and it also needs to be protected from contamination.

    We analyzed fluctuation in Beijing's air quality over 328 days, based on air quality grades and air quality data from 35 atmospheric monitoring stations. Our results show the air over Beijing is subject to pollution 152 days of the year, or 46.34%. Among all pollutants, fine particulates, solid or liquid, 2.5 μm or less in size (PM2.5), appeared most frequently as the primary pollutant: 249 days, or 76% of the sample year (328 days). Nitrogen dioxide (NO2) and coarse particulates (PM10) cause the least pollution, appearing only 7 and 3 days, or 2 and 1% of the sample year, respectively. In Beijing, fine particulates like PM2.5 vary seasonally: 154.54 ± 18.60 in winter > 145.22 ± 18.61 in spring > 140.16 ± 20.76 in autumn > 122.37 ± 13.42 in summer. Air quality is best in August and worst in December, while various districts in Beijing experience different air quality. To be specific, from south to north and from west to east, air quality tends to improve. Meteorological elements have a constraining effect on air pollutants, which means there is a linear correlation between the air quality index and humidity, rainfall, wind speed, and temperature. Under a typical pollution scenario, the higher the air quality index (AQI) value, the lower the wind speed and the greater the relative humidity; the lower the AQI value, the higher the wind speed and lower the relative humidity. Analysis of influencing factors reveals that the air pollution is mainly particulate matter produced by burning coal, vehicle emissions, volatile oils and gas, fast development of food services, emissions from the surrounding region, and natural dust clouds formed in arid areas to the northwest. Topography affects the distribution of meteorological conditions, in turn varying air quality over the region from one location to another. Human activities also exercise impact on urban air quality with dual functions.

    The European Union Water Framework Directive requires the achievement of environmental objectives for the ecological quality of water bodies. A comparable implementation of the Directive throughout member countries of the European Union is necessary to verify equal protection of surface waters. The Directive specifies that member states determine ecological quality by means of biological indices. To improve comparability of water quality assessment, this research carried out an intercalibration trial between the Slovak Saprobic Index and the Italian protocol of the Extended Biotic Index, as part of a cooperative program between Italy and the Slovak Republic. When assessing streams with no or low pollution, statistics showed similar results for both methods. In contrast, the comparison of indices was not accurate in the case of severely affected waters. Reliable conversion formulas are feasible to transform the Italian Extended Biotic Index into the Slovak Saprobic Index, and not vice versa.

    The comparison with National Ambient Air Quality Standards does not always depict a true picture of the Air Quality Status of a study area. As an alternative an index that measures depreciation in Air Quality on more realistic terms has been proposed and applied to the ambient air monitoring data collected from some areas of Korba Coalfields in India. Results have been discussed in detail to illustrate the application of the proposed index and utility in bringing out more realistic air quality assessment.

    Psoriatic arthritis (PsA) has a strong negative impact on the quality of life of patients. The Psoriatic Arthritis Quality of Life (PsAQoL) questionnaire is a disease-specific instrument developed to measure the quality of life in patients with PsA. The aims of this study were to culturally adapt the questionnaire for Portugal and evaluate its reliability and validity in patients with PsA. The original UK English version of the PsAQoL was translated into Portuguese by a bilingual and lay panel. Structured cognitive debriefing interviews were conducted with ten PsA patients. The Portuguese PsAQoL was subsequently applied to PsA patients followed at the Rheumatology Department of Centro Hospitalar do Baixo Vouga, E.P.E. To assess reproducibility, 30 patients with PsA completed the Portuguese PsAQoL on two occasions, 2 weeks apart. A larger sample was recruited to determine internal consistency and construct validity. The Nottingham Health Profile (NHP) was used as a comparator instrument. Translation and adaptation were successful. Cronbach´s alpha for the Portuguese version of the PsAQoL was 0.91 and the test-retest reliability was 0.93. The PsAQoL could distinguish between groups of patients defined by self-reported general health status, self-reported severity of PsA and flare of arthritis. There was a positive correlation between the total score of the PsAQoL and each of the sections of the NHP. The Portuguese version of the PsAQoL was found to be relevant, understandable and easy to complete, reliable and valid.

    The aim was to develop and test a questionnaire for use in telephone interviews concerning patient evaluation of geriatric care and rehabilitation. Instrument development was performed comprising qualitative interviews, construction of items, content validation, pilot study and data collection for evaluation of care and rehabilitation, clinical utility, reliability and construct validity. Qualitative interviews were performed with 12 elderly participants. The qualitative interviews formed the basis for the construction of 45 items. An expert panel performed a content validation of the questionnaire resulting in a revised version. A pilot study comprised 29 participants recently discharged from geriatric wards and the main data collection comprised 221 participants. Inclusion criteria were being able to perform a telephone interview and willingness to participate. Clinical utility was examined through questions to the interviewers, answered in writing. Cronbach's alpha coefficient was 0.79. According to a factor analysis and the evaluation of clinical utility, the underlying dimensions of the final revised questionnaire concern 'Respect and safety', 'Information and participation' and 'Rehabilitation interventions', scored in 18 items. In addition, one global item concerns satisfaction with care, resulting in 19 items in total. The revised questionnaire was named PaPeR, Patient Perspective on care and Rehabilitation. The questionnaire is considered valid, reliable and judged to have good clinical utility. The time consumption for the telephone interview is about 10-20 minutes. The questionnaire is useful in defining areas for potential quality improvement in geriatric wards.

    Work-related stressors are associated with low sleep quality. However, few studies have reported an association between role stressors and sleep quality. To elucidate the association between role stressors (including role conflict and ambiguity) and sleep quality. Cross-sectional study of daytime workers whose sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Work-related stressors, including role stressors, were assessed using the Generic Job Stress Questionnaire (GJSQ). The association between sleep quality and work-related stressors was investigated by logistic regression analysis. A total of 243 participants completed questionnaires were received (response rate 71%); 86 participants reported poor sleep quality, based on a global PSQI score ≥6. Multivariable logistic regression analysis revealed that higher role ambiguity was associated with global PSQI scores ≥6, and that role conflict was significantly associated with sleep problems, including sleep disturbance and daytime dysfunction. These results suggest that high role stress is associated with low sleep quality, and that this association should be considered an important determinant of the health of workers.

    Air quality is closely related to quality of life. Air pollution forecasting plays a vital role in air pollution warnings and controlling. However, it is difficult to attain accurate forecasts for air pollution indexes because the original data are non-stationary and chaotic. The existing forecasting methods, such as multiple linear models, autoregressive integrated moving average (ARIMA) and support vector regression (SVR), cannot fully capture the information from series of pollution indexes. Therefore, new effective techniques need to be proposed to forecast air pollution indexes. The main purpose of this research is to develop effective forecasting models for regional air quality indexes (AQI) to address the problems above and enhance forecasting accuracy. Therefore, two hybrid models (EMD-SVR-Hybrid and EMD-IMFs-Hybrid) are proposed to forecast AQI data. The main steps of the EMD-SVR-Hybrid model are as follows: the data preprocessing technique EMD (empirical mode decomposition) is utilized to sift the original AQI data to obtain one group of smoother IMFs (intrinsic mode functions) and a noise series, where the IMFs contain the important information (level, fluctuations and others) from the original AQI series. LS-SVR is applied to forecast the sum of the IMFs, and then, S-ARIMA (seasonal ARIMA) is employed to forecast the residual sequence of LS-SVR. In addition, EMD-IMFs-Hybrid first separately forecasts the IMFs via statistical models and sums the forecasting results of the IMFs as EMD-IMFs. Then, S-ARIMA is employed to forecast the residuals of EMD-IMFs. To certify the proposed hybrid model, AQI data from June 2014 to August 2015 collected from Xingtai in China are utilized as a test case to investigate the empirical research. In terms of some of the forecasting assessment measures, the AQI forecasting results of Xingtai show that the two proposed hybrid models are superior to ARIMA, SVR, GRNN, EMD-GRNN, Wavelet-GRNN and Wavelet-SVR. Therefore, the

    to obtain a valid and reliable GERD-QOL questionnaire for Indonesian application. at the initial stage, the GERD-QOL questionnaire was first translated into Indonesian language and the translated questionnaire was subsequently translated back into the original language (back-to-back translation). The results were evaluated by the researcher team and therefore, an Indonesian version of GERD-QOL questionnaire was developed. Ninety-one patients who had been clinically diagnosed with GERD based on the Montreal criteria were interviewed using the Indonesian version of GERD-QOL questionnaire and the SF 36 questionnaire. The validity was evaluated using a method of construct validity and external validity, and reliability can be tested by the method of internal consistency and test retest. the Indonesian version of GERD-QOL questionnaire had a good internal consistency reliability with a Cronbach Alpha of 0.687-0.842 and a good test retest reliability with an intra-class correlation coefficient of 0.756-0.936; p<0.05). The questionnaire had also been demonstrated to have a good validity with a proven high correlation to each question of SF-36 (p<0.05). the Indonesian version of GERD-QOL questionnaire has been proven valid and reliable to evaluate the quality of life of GERD patients.

    Validation of the PROSQOLI questionnaire adapted to Spanish, pursing an instrument to evaluate, in the common clinical practice, the quality of life in patients with locally advanced or disseminated prostate cancer in our country. A cross-sectional prospective study was designed in 750 patients (150 centers) with disseminated or locally advanced prostate cancer (TNM criterion) who came to the scheduled check-up. Socio-demographic and clinical data of the participants were collected. The subjects filled out the PROSQOLI and EQ-5D questionnaires. The analysis included 561 cases that met the selection criteria. The psychometric characteristics (feasibility, validity and reliability) of the adapted PROSQOLI questionnaire were studied. Mean age was 73.63 (7.59) years. A total of 72.01% of the participants had locally advanced disease. In 28.16%, the primary treatment was radiotherapy, in 12.30% it was prostatectomy. A total of 83.48% received hormone treatment. The mean for each scale of the PROSQOLI questionnaire varied from 68.86 to 74.51. The percentage of no response was less than 3% for each scale. The percentage of subjects with minimum score in any scale was negligible, and the maximum score did not surpass 5%. Mean time to fill out the questionnaire was 109.42 (101.00) seconds. Cronbach's α coefficient was 0.937 and the total item correlation was superior to 0.7 for all the items. Correlations with the EQ-5D questionnaire were moderate. Scores on the questionnaire were associated to all the parameters studied related to the disease. The adapted questionnaire has adequate psychometric properties for its use in research and in the clinical practice. Copyright © 2011 AEU. Published by Elsevier España. All rights reserved.

    It has been shown that the biggest dissatisfier for uncomplicated cataract surgery patients is pseudophakic dysphotopsia (PD). While edge design of an intraocular lens (IOL) impacts this problem, refractive index is still controversial as to its impact. This retrospective cohort study was designed to determine the role of increasing refractive index in PD. This study was conducted at the John A. Moran Eye Center, University of Utah, USA. A retrospective chart review identified patients who received one of two hydrophobic acrylic single piece IOLs (AcrySof WF SP [SN60WF] or Tecnis SP [ZCB00]), which differed mainly by refractive index (1.55 versus 1.47). Eighty-seven patients who had received implantation of a one-piece hydrophobic acrylic IOL were enrolled. Patients were included if the surgery had been uncomplicated and took place at least a year before study participation. All eligible patients had 20/20 best corrected vision, without any disease known to impact visual quality. In addition to conducting a record review, the enrolled patients were surveyed for PD, using a modified National Eye Institute Visual Function questionnaire, as well as for overall satisfaction with visual quality. Statistical analysis demonstrated no difference between the two cohorts regarding PD, general visual function, and overall visual satisfaction. The study suggests that with the two IOLs assessed, increasing the refractive index does not increase incidence of PD or decrease overall visual satisfaction.

    This study aimed to evaluate the psychometric properties and scoring pattern of the Brazilian version of the three-factor eating questionnaire-r21 (TFEQ-R21). Data were collected from 410 undergraduate students. Confirmatory factor analysis was conducted to examine the factor structure of the TFEQ-R21. Convergent and discriminant validity also was assessed. Cluster analysis was performed to investigate scoring patterns. In assessing the quality setting, the model was considered satisfactory (χ 2 /gl = 2.24, CFI = 0.97, TLI = 0.96, RMSEA = 0.05). The instrument was also considered appropriate in relation to the discriminant and convergent validity. There was a positive correlation between body mass index and the dimensions of cognitive restraint (r s  = 0.449, p < 0.001) and emotional eating (r s  = 0.112, p = 0.023). Using cluster analysis three respondent profiles were identified. The profile "A" was associated with appropriate weight, the "B" was characterized by high scores in cognitive restraint dimension, and the cluster "C" focused individuals who had higher scores on the uncontrolled eating and emotional eating dimensions. The Brazilian version of TFEQ-R21 has adequate psychometric properties, and the identified response profiles offer a promising prospect for its use in clinical practice, in weight loss interventions.

    Even though health-related quality of life (HRQOL) is considered an important component of bariatric surgery outcome, there is a lack of HRQOL measures relevant for preoperative and postoperative patients. The objective of the current study was to develop a new instrument assessing HRQOL prior to and following bariatric surgery, entitled Quality of Life for Obesity Surgery (QOLOS) Questionnaire. Topics for the QOLOS were initially generated via open-ended interviews and focus groups with 19 postoperative bariatric surgery patients. Qualitative analysis resulted in 250 items, which were rated by patients (n = 101) and experts (n = 69) in terms of their importance. A total of 120 items were retained for further evaluation and administered to 220 preoperative patients and 219 postoperative patients. They also completed a battery of other assessments to analyze issues of construct validity. Analyses resulted in a 36-item section 1 QOLOS form targeting both preoperative and postoperative aspects across seven domains (eating disturbances, physical functioning, body satisfaction, family support, social discrimination, positive activities, partnership) and a 20-item section 2 QOLOS form focusing on postoperative concerns only (domains: excess skin, eating adjustment, dumping, satisfaction with surgery). Subscales of both sections showed acceptable to excellent internal consistency (Cronbach's α 0.72 to 0.95) and good convergent and discriminant validity. The QOLOS represents a reliable and valid instrument to assess HRQOL in preoperative and postoperative patients. Future studies should test the questionnaire in larger samples consisting of patients undergoing different types of surgery.

    Aim: The aim of this study was to examine the relation between body mass index (BMI) and functional level and health-related quality of life in children with cerebral palsy (CP). Material and Methods: Two hundred seventy-eight children with CP aged between 2 and 18 years were included in the study. The sociodemographic properties of the children were recorded. Their functional independence levels were assessed with WeeFIM and their health-related quality of life levels were assessed with the Child Health Questionnaire-Parent Form (PF-50). Approval was obtained from the ethics committee of Abant İzzet Baysal University Medical Faculty for this study (Number: 2008/100-77). Results: When classified by body mass index, 26.3% of the children had a normal body weight, 5.4% were overweight, 11.5% were obese and 56.8% had a low body weight. The rate of low body weight was higher in children with moderate and severe CP (52.7% and 53.8%, respectively), while the rate of obesity was higher in children with mild CP who could walk (7.1%). A significant difference was found in children with CP with a normal body weight, overweight children with CP, obese children with CP and children with CP with a low body weight in terms of the total WeeFIM score and the variables of quality of life including physical functionality and role/social limitations because of physical health (p<0.05). In the correlation analysis, a positive correlation was found between WeeFIM and BMI and the subdimensions of role/social limitations because of emotional or behavioral difficulties, pain and discomfort and self-esteem (p<0.05). Conclusions: Our results showed that BMI affected functional independence and health-related quality of life in children with CP and this was more prominent in children who had severe CP and low BMI values. More studies are needed in this area. PMID:26078648

    Background High quality care is crucial in ensuring that women and newborns receive interventions that may prevent and treat birth-related complications. As facility deliveries increase in developing countries, there are concerns about service quality. Observation is the gold standard for clinical quality assessment, but existing observation-based measures of obstetric quality of care are lengthy and difficult to administer. There is a lack of consensus on quality indicators for routine intrapartum and immediate postpartum care, including essential newborn care. This study identified key dimensions of the quality of the process of intrapartum and immediate postpartum care (QoPIIPC) in facility deliveries and developed a quality assessment measure representing these dimensions. Methods and Findings Global maternal and neonatal care experts identified key dimensions of QoPIIPC through a modified Delphi process. Experts also rated indicators of these dimensions from a comprehensive delivery observation checklist used in quality surveys in sub-Saharan African countries. Potential QoPIIPC indices were developed from combinations of highly-rated indicators. Face, content, and criterion validation of these indices was conducted using data from observations of 1,145 deliveries in Kenya, Madagascar, and Tanzania (including Zanzibar). A best-performing index was selected, composed of 20 indicators of intrapartum/immediate postpartum care, including essential newborn care. This index represented most dimensions of QoPIIPC and effectively discriminated between poorly and well-performed deliveries. Conclusions As facility deliveries increase and the global community pays greater attention to the role of care quality in achieving further maternal and newborn mortality reduction, the QoPIIPC index may be a valuable measure. This index complements and addresses gaps in currently used quality assessment tools. Further evaluation of index usability and reliability is needed. The

    Goals of the current study were to (1) conduct initial validation of a new Paradoxical Vocal Fold Movement Disorder Screening Questionnaire (PVFMD-SQ); (2) determine if symptom-based questionnaires can discriminate between patients with confirmed PVFMD and those with diagnosed uncontrolled asthma without clinical suspicion for PVFMD; and (3) determine if a new questionnaire with diagnostic specificity could be created from a combination of significant items on previously validated questionnaires. This is a prospective, case-controlled study of patients with PVFMD only and asthma only, who completed five questionnaires: Dyspnea Index, Reflux Symptom Index, Voice Handicap Index-10, Sino-Nasal Questionnaire, and PVFMD-SQ. Factor analysis was completed on the new PVFMD-SQ, and the discrimination ability of selected factors was assessed by receiver operating characteristics curve. The factor with the greatest discriminatory ability was selected to create one diagnostic questionnaire, and scores for each participant were calculated to estimate how well the factor correlated with a PVFMD or asthma diagnosis. Mean scores on all questionnaires were compared to test their discriminatory ability. Patients with PVFMD showed greater voice handicap and reflux symptoms than patients with asthma. A 15-item one-factor questionnaire was developed from the original PVFMD-SQ, with a sensitivity of 89% and specificity of 73% for diagnosing asthma versus PVFMD. The combined questionnaires resulted in four factors, none of which showed discriminatory ability between PVFMD and asthma. This study represents the first time that a patient symptom-based screening tool has shown diagnostic sensitivity to differentiate PVFMD from asthma in a cohort of symptomatic patients.

    The aim of this study was to evaluate the validity and reliability of the Main Meal Quality Index when applied on the UK population. The indicator was developed to assess meal quality in different populations, and is composed of 10 components: fruit, vegetables (excluding potatoes), ratio of animal protein to total protein, fiber, carbohydrate, total fat, saturated fat, processed meat, sugary beverages and desserts, and energy density, resulting in a score range of 0-100 points. The performance of the indicator was measured using strategies for assessing content validity, construct validity, discriminant validity and reliability, including principal component analysis, linear regression models and Cronbach's alpha. The indicator presented good reliability. The Main Meal Quality Index has been shown to be valid for use as an instrument to evaluate, monitor and compare the quality of meals consumed by adults in the United Kingdom.

    Health-related quality of life is usually reported for specific rather than heterogeneous populations such as those treated in routine anesthesia practice. The 8-item short-form generic health-related quality-of-life questionnaire (SF-8) is a candidate instrument for this setting. The authors evaluated the feasibility, reliability, validity, and responsiveness to change of the Spanish version of SF-8 in a population-based surgical cohort. Recruiting patients from a large population-based study of risk factors for pulmonary complications, before surgery, the authors administered the 1-week recall SF-8 to 2,991 patients undergoing nonobstetric elective or emergency surgery in 59 hospitals, each of which collected data on seven randomly assigned days in 2006. The SF-8 was administered again 3 months later. Reliability was evaluated using the Cronbach alpha coefficient and validity by comparing physical and mental component summary SF-8 scores with clinical variables. Responsiveness after surgery was evaluated using the standardized response mean. Cronbach alpha for the overall test was 0.92. Physical and mental component summary scores and all individual scores were lower (worse quality of life) in women (P < 0. 01) and decreased with age (P < 0.01). Preoperative scores were lower for those in worse clinical condition (higher body mass index, American Society of Anesthesiologists physical status class, or surgical risk scores), with preoperative respiratory symptoms, and in emergency situations (P < 0.01). The standardized response mean ranged from 0.1 to 0.5. The SF-8 is a feasible, reliable, valid, and responsive instrument for assessing health-related quality of life in a broad-spectrum surgical population.

    To determine the measurement properties of the Persian language version of the Graves orbitopathy quality of life questionnaire (GO-QOL). Following a systematic translation and cultural adaptation process, 141 consecutive unselected thyroid eye disease (TED) patients answered the Persian GO-QOL and underwent complete ophthalmic examination. The questionnaire was again completed by 60 patients on the second visit, 2-4 weeks later. Construct validity (cross-cultural validity, structural validity and hypotheses testing), reliability (internal consistency and test-retest reliability), and floor and ceiling effects of the Persian version of the GO-QOL were evaluated. Furthermore, Rasch analysis was used to assess its psychometric properties. Cross-cultural validity was established by back-translation techniques, committee review and pretesting techniques. Bi-dimensionality of the questionnaire was confirmed by factor analysis. Construct validity was also supported through confirmation of 6 out of 8 predefined hypotheses. Cronbach's α and intraclass correlation coefficient (ICC) were 0.650 and 0.859 for visual functioning and 0.875 and 0.896 for appearance subscale, respectively. Mean quality of life (QOL) scores for visual functioning and appearance were 78.18 (standard deviation, SD, 21.57) and 56.25 (SD 26.87), respectively. Person reliabilities from the Rasch rating scale model for both visual functioning and appearance revealed an acceptable internal consistency for the Persian GO-QOL. The Persian GO-QOL questionnaire is a valid and reliable tool with good psychometric properties in evaluation of Persian-speaking patients with TED. Applying Rasch analysis to future versions of the GO-QOL is recommended in order to perform tests for linearity between the estimated item measures in different versions.

    There are few specific evaluation forms for evaluating the quality of life among patients with chronic constipation. Our study aimed to determine the validity and reliability of the translated Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire for the Turkish population because evidence of its reliability and validity is required to justify its use in other studies and clinical practice. This study included 154 patients with constipation who were treated at the Department of Gastroenterology, Dokuz Eylül University Hospital between January and June 2012. The translated PAC-QOL questionnaire was completed by patients at the clinic and also at a 2-week follow-up to test its reliability. Cronbach's alpha coefficient (internal consistency) was 0.91 (good) for the translated PAC-QOL questionnaire. Time validity was evaluated using the intraclass correlation coefficient (ICC) method, and the ICC value for all questions was confirmed as 0.68 at the 2-week follow-up. The validity of the tool in the study group was evaluated using factor analysis, and the results were highly significant (Kaiser-Meyer-Olkin value: 0.857; Bartlett's test: p=0.001). Questions were categorized according to six factors based on the factor analysis, and these factors explained 65.1% of the total variation. For hypothesis verification of the tool, the correlation coefficient for PAC-QOL and PAC Symptoms (PAC-SYM) was r=0.577 (p<0.001), whereas the correlation coefficient for PAC-QOL and constipation severity score was r=0.457 (p<0.001). The PAC-QOL questionnaire was reliable, although not valid because of the limited sample group.

    To examine the association between a dietary fat quality index (FQI), and the risk of incident cardiovascular events or deaths in the Seguimiento Universidad de Navarra (SUN) cohort. Longitudinal analysis during 10.1 years of median follow-up. Cox models were used to estimate adjusted hazard ratios (HR) of incident cardiovascular diseases (CVD) according to tertiles of FQI and of different fat subtypes. University of Navarra, Spain. 19,341 middle-aged adults. Fat intake was measured with a validated food-frequency questionnaire. The FQI was calculated according to the ratio: (monounsaturated+polyunsaturated) / (saturated+trans fatty acids). We observed 140 incident cases of CVD. No association was found for FQI (HR=0.94, 95 %CI 0.61-1.47 for the highest vs the lowest tertile, p for trend=0.884). No significant associations were found for different dietary fat subtypes on CVD risk. The results suggest no clear association between a higher FQI and a higher amount of energy from fat and incidence of CVD (p for interaction: 0.259 and p for trend only among participants with a percentage of energy from fat ≥35% of total energy: 0.272). In this Mediterranean cohort, the FQI was not associated with cardiovascular events. A "heart-healthy diet" should focus its attention on dietary fat sources and should use an overall dietary pattern approach, rather than limiting the focus on fat subtypes. More research is needed to validate dietary advice on specific fatty acids intake or saturated fatty acids replacements for reducing CVD risk.

One hundred and fifty-five CEOs and 155 quality managers. One hundred and fifty-five randomly selected acute care hospitals in seven European countries (Czech Republic, France, Germany, Poland, Portugal, Spain and Turkey). Main outcome measure(s) Three constructs reflecting quality management based on questionnaire and audit data: (i) Quality Management System Index, (ii) Quality Management Compliance Index and (iii) Clinical Quality Implementation Index. The main predictor was whether quality performance was on the executive board's agenda. Discussing quality performance at executive board meetings more often was associated with a higher quality management system score (regression coefficient b = 2.53; SE = 1.16; P = 0.030). We found a trend in the associations of discussing quality performance with quality compliance and clinical quality implementation. PEP did not modify these relationships. Having quality as an item on the executive board's agenda allows them to review and discuss quality performance more often in order to improve their hospital's quality management. Generally, and as this study found, having quality on the executive board's agenda matters.

  16. 'Equivalence' and the translation and adaptation of health-related quality of life questionnaires.

    The increasing use of health-related quality of life (HRQOL) questionnaires in multinational studies has resulted in the translation of many existing measures. Guidelines for translation have been published, and there has been some discussion of how to achieve and assess equivalence between source and target questionnaires. Our reading in this area had led us, however, to the conclusion that different types of equivalence were not clearly defined, and that a theoretical framework for equivalence was lacking. To confirm this we reviewed definitions of equivalence in the HRQOL literature on the use of generic questionnaires in multicultural settings. The literature review revealed: definitions of 19 different types of equivalence; vague or conflicting definitions, particularly in the case of conceptual equivalence; and the use of many redundant terms. We discuss these findings in the light of a framework adapted from cross-cultural psychology for describing three different orientations to cross-cultural research: absolutism, universalism and relativism. We suggest that the HRQOL field has generally adopted an absolutist approach and that this may account for some of the confusion in this area. We conclude by suggesting that there is an urgent need for a standardized terminology within the HRQOL field, by offering a standard definition of conceptual equivalence, and by suggesting that the adoption of a universalist orientation would require substantial changes to guidelines and more empirical work on the conceptualization of HRQOL in different cultures.

    We performed the French translation and cross-cultural adaptation of the Severe Respiratory Insufficiency (SRI) questionnaire. Written and validated in German, this questionnaire evaluates health-related quality of life in patients treated with domiciliary ventilation for chronic respiratory failure. Four bilingual German-French translators and a linguist were recruited to produce translations and back-translations of the questionnaire constituted of 49 items in seven domains. Two successive versions were generated and compared to the original questionnaire. The difficulty of the translation and the naturalness were quantified for each item using a 1-10 scale and their equivalence to their original counterpart was graded from A to C. The translated questionnaire was finally tested in a pilot study, which included 15 representative patients. The difficulty of the first translation and the first back-translation was respectively quantified as 2.5 (range 1-5.5) and 1.5 (range 1-6) on the 10-point scale (P=0.0014). The naturalness and the equivalence of 8/49 items were considered as insufficient, which led to the production of a second translation and a second back-translation. The meanings of two items needed clarification during the pilot study. The French translation of the SRI questionnaire represents a new instrument for clinical research in patients treated with domiciliary ventilation for chronic respiratory failure. Its validity needs to be tested in a multicenter study. Copyright © 2012 SPLF. Published by Elsevier Masson SAS. All rights reserved.

    Cough is a prominent symptom across a range of common chronic respiratory diseases and impacts considerably on patient health status. We undertook a cross-sectional comparison of scores from two cough-specific health-related quality of life (HRQoL) questionnaires, the Leicester Cough Questionnaire (LCQ), and the Cough Quality of Life Questionnaire (CQLQ), together with a generic HRQoL measure, the EuroQol. Questionnaires were administered to and spirometry performed on 147 outpatients with chronic cough (n = 83), COPD (n = 18), asthma (n = 20), and bronchiectasis (n = 26). There was no significant difference in the LCQ and CQLQ total scores between groups (p = 0.24 and p = 0.26, respectively). Exploratory analyses of questionnaire subdomains revealed differences in psychosocial issues and functional impairment between the four groups (p = 0.01 and p = 0.05, respectively). CQLQ scores indicated that chronic coughers have more psychosocial issues than patients with bronchiectasis (p = 0.03) but less functional impairment than COPD patients (p = 0.04). There was a significant difference in generic health status across the four disease groups (p = 0.04), with poorest health status in COPD patients. A significant inverse correlation was observed between CQLQ and LCQ in each disease group (chronic cough r = - 0.56, p < 0.001; COPD r = - 0.49, p = 0.04; asthma r = - 0.94, p < 0.001; and bronchiectasis r = - 0.88, p < 0.001). There was no correlation between cough questionnaire scores and FEV(1) in any group, although a significant correlation between EuroQol visual analog scale component and FEV(1) (r = 0.639, p = 0.004) was observed in COPD patients. Cough adversely affects health status across a range of common respiratory diseases. The LCQ and CQLQ can each provide important additional information concerning the impact of cough.

    The clinical evaluation system for therapeutic effects of tumor, which focuses on survival period and tumor response rate, has been proved not very proper for evaluating the therapeutic effects of traditional Chinese medicine (TCM). Quality of life (QOL) has been introduced into the effective evaluation system of TCM and integrative medicine because of its similarity in concept and extension with TCM at theory basis, syndrome differentiation-treatment, and evaluation of therapeutic effects. But there are no QOL questionnaires which can evaluate the therapeutic effects of TCM and integrative medicine precisely. This article discussed the necessity and significance of developing QOL questionnaire special for TCM.

    Background: Psychologic factors affect how patients with COPD respond to attempts to improve their self-management skills. Learned helplessness may be one such factor, but there is no validated measure of helplessness in COPD. Methods: We administered a new COPD Helplessness Index (CHI) to 1,202 patients with COPD. Concurrent validity was assessed through association of the CHI with established psychosocial measures and COPD severity. The association of helplessness with incident COPD exacerbations was then examined by following subjects over a median 2.1 years, defining COPD exacerbations as COPD-related hospitalizations or ED visits. Results: The CHI demonstrated internal consistency (Cronbach α = 0.75); factor analysis was consistent with the CHI representing a single construct. Greater CHI-measured helplessness correlated with greater COPD severity assessed by the BODE (Body-mass, Obstruction, Dyspnea, Exercise) Index (r = 0.34; P < .001). Higher CHI scores were associated with worse generic (Short Form-12, Physical Component Summary Score) and respiratory-specific (Airways Questionnaire 20) health-related quality of life, greater depressive symptoms, and higher anxiety (all P < .001). Controlling for sociodemographics and smoking status, helplessness was prospectively associated with incident COPD exacerbations (hazard ratio = 1.31; P < .001). After also controlling for the BODE Index, helplessness remained predictive of COPD exacerbations among subjects with BODE Index ≤ median (hazard ratio = 1.35; P = .01), but not among subjects with higher BODE Index values (hazard ratio = 0.93; P = .34). Conclusions: The CHI is an internally consistent and valid measure, concurrently associated with health status and predictively associated with COPD exacerbations. The CHI may prove a useful tool in analyzing differential clinical responses mediated by patient-centered attributes. PMID:19837823

    Treatment for metastatic cutaneous head and neck squamous cell carcinoma is usually multimodal and associated with morbidity. This study aimed to evaluate the impact of treatment on patients' quality of life. Cross-sectional survey of 42 patients (35 men, 7 women) at least 6 months after metastatic cutaneous head and neck squamous cell carcinoma treatment, using two standardised quality of life questionnaires: the Functional Assessment of Cancer Therapy - Head and Neck questionnaire and the Facial Disability Index, with statistical analysis to identify potential predictors of outcome. Female gender correlated with significantly lower Facial Disability Index physical function scores (p = 0.017). Alcohol consumption correlated with significantly better scores for Functional Assessment social well-being (p = 0.016), general total score (p = 0.041) and overall total score (p = 0.033), and for Facial Disability Index physical function (p = 0.034). Marital status, education, employment, chemotherapy, time from last treatment, parotidectomy and facial nerve sacrifice did not affect quality of life. The commonest patient complaints were dry mouth (76 per cent), altered voice quality and strength (55 per cent), and physical appearance (45 per cent). Female gender predicts worse quality of life, while alcohol consumption (versus none) predicted for better quality of life.

A methodological study based on 3-month follow-up data for evaluating psychometric properties of health-related quality of life (HRQOL) questionnaires. Cardiac rehabilitation center at a cardiovascular research institute. Eligible patients with HF (N=60). Exercise training in cardiac rehabilitation. The SF-36, the MacNew Heart Disease questionnaire, and the Minnesota Living With Heart Failure Questionnaire (MLHFQ) and New York Heart Association functional classification. Items from the MLHFQ and the MacNew questionnaire had acceptable correlations (r>.30, P<.05). Internal consistency and test-retest reliability were adequate at ≥0.7 for the MLHFQ subscales. Correlations for the MLHFQ and the MacNew with SF-36 similar items ranged from .28 to .50 and from .26 to .60, respectively. Similar scales from the MacNew and MLHFQ showed strong correlations at baseline and follow-up, supporting the convergent validity. Improvement in HRQOL was significant for all MLHFQ subscales (P<.001) and the MacNew emotional (P<.05) and social (P<.001) subscales. The MLHFQ demonstrated the most responsiveness to changes and discriminated disease severity the best. The follow-up scores for all MLHFQ and 2 MacNew subscales were significantly greater in patients who improved compared with those who showed no change or deteriorated. The MLHFQ was more responsive to changes of HRQOL than the MacNew questionnaire over time in patients with HF. The MacNew questionnaire was more responsive to changes than the SF-36.

    Pollution levels have been increasing in water ecosystems worldwide. A water quality index (WQI) is an available tool to approximate the quality of water and facilitate the work of decision-makers by grouping and analyzing numerous parameters with a single numerical classification system. The objective of this study was to develop a WQI for a dam used for irrigation of about 5000 ha of agricultural land. The dam, La Vega, is located in Teuchitlan, Jalisco, Mexico. Seven sites were selected for water sampling and samples were collected in March, June, July, September, and December 2014 in an initial effort to develop a WQI for the dam. The WQI methodology, which was recommended by the Mexican National Water Commission (CNA), was used. The parameters employed to calculate the WQI were pH, electrical conductivity (EC), dissolved oxygen (DO), total dissolved solids (TDS), total hardness (TH), alkalinity (Alk), total phosphorous (TP), Cl−, NO3, SO4, Ca, Mg, K, B, As, Cu, and Zn. No significant differences in WQI values were found among the seven sampling sites along the dam. However, seasonal differences in WQI were noted. In March and June, water quality was categorized as poor. By July and September, water quality was classified as medium to good. Quality then decreased, and by December water quality was classified as medium to poor. In conclusion, water treatment must be applied before waters from La Vega dam reservoir can be used for irrigation or other purposes. It is recommended that the water quality at La Vega dam is continually monitored for several years in order to confirm the findings of this short-term study. PMID:28468230

    [Purpose] Maintaining high quality of life is crucial for the rehabilitation of patients with Parkinson's disease. The quality of life scales currently in use do not assess all quality of life domains or their importance for each individual. Therefore, a new quality of life measure, the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting, was used to investigate quality of life in people with Parkinson's disease. [Subjects and Methods] Fifteen people with idiopathic Parkinson's disaese (average age = 80.0 years, standard deviation = 10.3 years, Hoehn & Yahr stages 1-4) were interviewed using the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting. Its quality of life constructs were tested by comparing them against disease-specific quality of life (39-items Parkinson's Disease Questionnaire), motor functioning (Unified Parkinson's Disease Rating Scale Part III), and activities of daily living (Barthel Index). [Results] Social connections such as "family" and "friends" were revealed as important constructs of life satisfaction. The Schedule for the Evaluation of Individual Quality of Life-Direct Weighting was not significantly correlated with the 39-items Parkinson's Disease Questionnaire, Unified Parkinson's Disease Rating Scale Part III, or Barthel Index but was significantly correlated with the "communication" dimension of the 39-items Parkinson's Disease Questionnaire. [Conclusion] The Schedule for the Evaluation of Individual Quality of Life-Direct Weighting detected various domains of quality of life, especially social relationships with family and friends. "Being heard" was also revealed as an essential component of life satisfaction, as it provides patients with a feeling of acceptance and assurance, possibly resulting in better quality of life.

  8. Development and validation of a questionnaire assessing the quality of life impact of Colour Blindness (CBQoL).

    Congenital colour vision deficiency (CVD), commonly called 'colour blindness', affects around 8% of men and 0.4% of women. Although many aspects of health (e.g. change in colour of urine) and healthcare (e.g. coloured medication, colour-coded diagnostic tests), and modern life depend upon colour coding (e.g. graphs, maps, signals), the impact of colour blindness on everyday life is not generally considered a topic of importance. This study is the first to create and validate a questionnaire measuring the quality of life (QoL) impact of being colour blind. This study consisted of two phases. Firstly, the questionnaire design and development phase was led by an expert panel and piloted on a focus group. Secondly, an online sample of 128 men and 291 women filled in the questionnaire, and the psychometric properties of the questionnaire were analysed using principal components analysis (PCA). The scores of colour blind (CB) participants and normal-sighted controls, controlling for age and sex, were compared using matched t-tests. The PCA resulted in a questionnaire with three domains (or subscales): QoL for Health & Lifestyle, QoL for Work, and QoL for Emotions. Controlling for age, there was a significantly greater negative impact on QoL for CB people than normal-sighted controls in regards to confusion over colour in various aspects of their health (p = 5 × 10 -7 ), work (p = 1.3 × 10 -7 ), and emotional life (p = 6 × 10 -5 ). Colour blindness can significantly impact quality of life for health, emotions, and especially careers. The tool developed here could be useful in future clinical studies to measure changes in CBQoL in response to therapy in conditions where colour vision is affected. We also discuss ways in which everyday problems related to colour vision might be reduced, for example, workplaces could avoid colour coding where a non-colour alternative is possible.

    Few questionnaires on outpatients' satisfaction with hospital exist. All have been constructed without giving enough room for the patient's point of view in the validation procedure. The main objective was to develop, according to psychometric standards, a self-administered generic outpatient questionnaire exploring opinion on quality of hospital care. First, a qualitative phase was conducted to generate items and identify domains using critical analysis incident technique and literature review. A list of easily comprehensible non-redundant items was defined using Delphi technique and a pilot study on outpatients. This phase involved outpatients, patient association representatives and experts. The second step was a quantitative validation phase comprised a multicenter study in 3 hospitals, 10 departments and 1007 outpatients. It was designed to select items, identify dimensions, measure reliability, internal and concurrent validity. Patients were randomized according to the place of questionnaire completion (hospital v. home) (participation rate = 65%). Third, a mail-back study on 2 departments and 248 outpatients was conducted to replicate the validation (participation rate = 57%). A 27-item questionnaire comprising 4 subscales (appointment making, reception facilities, waiting time and consultation with the doctor). The factorial structure was satisfactory (loading >0.50 on each subscale for all items, except one item). Interscale correlations ranged from 0.42 to 0.59, Cronbach alpha coefficients ranged from 0.79 to 0.94. All Item-scale correlations were higher than 0.40. Test-retest intraclass coefficients ranged from 0.69 to 0.85. A unidimensional 9-item version was produced by selection of one third of the items within each subscale with the strongest loading on the principal component and the best item-scale correlation corrected for overlap. Factors related to satisfaction level independent from departments were age, previous consultations in the department

    Background Leadership and staffing are recognised as important factors for quality of care. This study examines the effects of ward leaders' task- and relationship-oriented leadership styles, staffing levels, ratio of registered nurses and ratio of unlicensed staff on three independent measures of quality of care. Methods A cross-sectional survey of forty nursing home wards throughout Norway was used to collect the data. Five sources of data were utilised: self-report questionnaires to 444 employees, interviews with and questionnaires to 13 nursing home directors and 40 ward managers, telephone interviews with 378 relatives and 900 hours of field observations. Separate multi-level analyses were conducted for quality of care assessed by relatives, staff and field observations respectively. Results Task-oriented leadership style had a significant positive relationship with two of the three quality of care indexes. In contrast, relationship-oriented leadership style was not significantly related to any of the indexes. The lack of significant effect for relationship-oriented leadership style was due to a strong correlation between the two leadership styles (r = 0.78). Staffing levels and ratio of registered nurses were not significantly related to any of the quality of care indexes. The ratio of unlicensed staff, however, showed a significant negative relationship to quality as assessed by relatives and field observations, but not to quality as assessed by staff. Conclusions Leaders in nursing homes should focus on active leadership and particularly task-oriented behaviour like structure, coordination, clarifying of staff roles and monitoring of operations to increase quality of care. Furthermore, nursing homes should minimize use of unlicensed staff and address factors related to high ratios of unlicensed staff, like low staff stability. The study indicates, however, that the relationship between staffing levels, ratio of registered nurses and quality of care is

    The Evaluative Linguistic Framework (ELF) was developed to judge the quality of health care texts for patients, based on systemic functional linguistic theory. This approach considers key variables such as context and structure, known to be important for communication. Our objective was to adapt the ELF to evaluate the quality of self-report questionnaires. We reviewed the Health Literacy Questionnaire using the ELF. On the basis of these data, we drafted the preliminary version of the Evaluative Linguistic Framework for Questionnaires (ELF-Q) and applied it to English- and French-language versions of two arthritis self-report questionnaires and to Spanish, Dutch, and Turkish versions of an arthritis questionnaire. The developed ELF-Q was found to be effective for evaluating questionnaires in English and in four other languages. It contains nine items with new descriptions and assessment probes. These include overall organizational or generic structure of the questionnaire, metadiscourse (or text about the text), headings, rhetorical elements (function of each "move" or stage of the text in relation to the reader), the writer-reader relationship, technicality of vocabulary, lexical density (proportion of content words in the text), format, and overall judgment. We added assessment responses on a two- or three-point Likert scale to complement the assessment probes and make the intent and meaning of the probes fully explicit for the questionnaire developer or assessor. The ELF-Q is a framework practical to use for the development or assessment of any type of self-report questionnaire. Its application can identify features of a self-report questionnaire that could be improved to optimize its comprehensibility.

    The best treatment for cataract patients, which allows to restore clear vision is implanting an artificial intraocular lens (IOL). The image quality of the lens has a significant impact on the quality of patient's vision. After a long exposure the implant to aqueous environment some defects appear in the artificial lenses. The defects generated in the IOL have different refractive indices. For example, glistening phenomenon is based on light scattering on the oval microvacuoles filled with an aqueous humor which refractive index value is about 1.34. Calcium deposits are another example of lens defects and they can be characterized by the refractive index 1.63. In the presented studies it was calculated how the difference between the refractive indices of the defect and the refractive index of the lens material affects the quality of image. The OpticStudio Professional program (from Radiant Zemax, LLC) was used for the construction of the numerical model of the eye with IOL and to calculate the characteristics of the retinal image. Retinal image quality was described in such characteristics as Point Spread Function (PSF) and the Optical Transfer Function with amplitude and phase. The results show a strong correlation between the refractive indices difference and retinal image quality.

    Drinking water is susceptible to the poor quality of contaminated water affecting the health of humans. Thus, it is an essential study to investigate factors affecting groundwater quality and its suitability for drinking uses. In this paper, the entropy theory, multivariate statistics, spatial autocorrelation index, and geostatistics are applied to characterize groundwater quality and its spatial variability in the Sylhet district of Bangladesh. A total of 91samples have been collected from wells (e.g., shallow, intermediate, and deep tube wells at 15-300-m depth) from the study area. The results show that NO 3 - , then SO 4 2- , and As are the most contributed parameters influencing the groundwater quality according to the entropy theory. The principal component analysis (PCA) and correlation coefficient also confirm the results of the entropy theory. However, Na + has the highest spatial autocorrelation and the most entropy, thus affecting the groundwater quality. Based on the entropy-weighted water quality index (EWQI) and groundwater quality index (GWQI) classifications, it is observed that 60.45 and 53.86% of water samples are classified as having an excellent to good qualities, while the remaining samples vary from medium to extremely poor quality domains for drinking purposes. Furthermore, the EWQI classification provides the more reasonable results than GWQIs due to its simplicity, accuracy, and ignoring of artificial weight. A Gaussian semivariogram model has been chosen to the best fit model, and groundwater quality indices have a weak spatial dependence, suggesting that both geogenic and anthropogenic factors play a pivotal role in spatial heterogeneity of groundwater quality oscillations.

    The purpose of this study was to assess the quality of life (QOL) and voice handicap in a sample of disease-free patients who had been treated at our center with radiotherapy (RT) or surgery for early glottic cancer. QOL and voice handicap were assessed using the European Organisation for Research and Treatment of Cancer (EORTC) questionnaires Quality of Life Questionnaire-Core 30-questions (QLQ-C30) and Quality of Life Questionnaire-Head and Neck 35-questions (QLQ-H&N35) and the Voice Handicap Index (VHI). Ninety-one patients completed the questionnaires. Fifty-nine patients (65%) were treated with RT and 32 (35%) with surgery. QOL scores for the sample recorded, moderate limitations in 6 areas, and more than moderate limitations (>30 of 100) in 2 areas. Significant differences were found in emotional functioning (88.5 vs 76.6) and social contact (4.6 vs 12.1) on the EORTC questionnaires and on the VHI (6.1 vs 12.8), which favored the RT group. In this cross-sectional study, voice quality, emotional functioning, and social contact were better in the RT group. © 2014 Wiley Periodicals, Inc.

    Objective The purpose of this study was to develop and validate a generic questionnaire to evaluate experiences and reported outcomes in patients who receive treatment across a range of healthcare sectors. Design Mixed-methods design including focus groups, pretests and field test. Setting The patient questionnaire was developed in the context of a nationwide program in Germany aimed at quality improvements across the healthcare sectors. Participants For the field test, 589 questionnaires were distributed to patients via 47 general practices. Main Measurements Descriptive item analyzes non-responder analysis and factor analysis (PCA). Retest coefficients (r) calculated by correlation of sum scores of PCA factors. Quality gaps were assessed by the proportion of responders choosing a response category defined as indicating shortcomings in quality of care. Results The conceptual phase showed good content validity. Four hundred and seventy-four patients who received a range of treatment across a range of sectors were included (response rate: 80.5%). Data analysis confirmed the construct, oriented to the patient care journey with a focus on transitions between healthcare sectors. Quality gaps were assessed for the topics ‘Indication’, including shared-decision-making (6 items, 24.5–62.9%) and ‘Discharge and Transition’ (10 items; 20.7–48.2%). Retest coefficients ranged from r = 0.671 until r = 0.855 and indicated good reliability. Low ratios of item-non-response (0.8–9.3%) confirmed a high acceptance by patients. Conclusions The number of patients with complex healthcare needs is increasing. Initiatives to expand quality assurance across organizational borders and healthcare sectors are therefore urgently needed. A validated questionnaire (called PEACS 1.0) is available to measure patients' experiences across healthcare sectors with a focus on quality improvement. PMID:24758750

    OBJECTIVE Develop an index to evaluate the maternal and neonatal hospital care of the Brazilian Unified Health System. METHODS This descriptive cross-sectional study of national scope was based on the structure-process-outcome framework proposed by Donabedian and on comprehensive health care. Data from the Hospital Information System and the National Registry of Health Establishments were used. The maternal and neonatal network of Brazilian Unified Health System consisted of 3,400 hospitals that performed at least 12 deliveries in 2009 or whose number of deliveries represented 10.0% or more of the total admissions in 2009. Relevance and reliability were defined as criteria for the selection of variables. Simple and composite indicators and the index of completeness were constructed and evaluated, and the distribution of maternal and neonatal hospital care was assessed in different regions of the country. RESULTS A total of 40 variables were selected, from which 27 single indicators, five composite indicators, and the index of completeness of care were built. Composite indicators were constructed by grouping simple indicators and included the following variables: hospital size, level of complexity, delivery care practice, recommended hospital practice, and epidemiological practice. The index of completeness of care grouped the five variables and classified them in ascending order, thereby yielding five levels of completeness of maternal and neonatal hospital care: very low, low, intermediate, high, and very high. The hospital network was predominantly of small size and low complexity, with inadequate child delivery care and poor development of recommended and epidemiological practices. The index showed that more than 80.0% hospitals had a low index of completeness of care and that most qualified heath care services were concentrated in the more developed regions of the country. CONCLUSIONS The index of completeness proved to be of great value for monitoring the

    Recent rise in fraudulent disability claims in the United States has resulted in psychologists being increasingly called upon to use psychological tests to determine whether disability claims based on psychological or somatic/pain complaints are legitimate. To examine two brief measures, Modified Somatic Perception Questionnaire (MSPQ) and the Pain Disability Index (PDI), and their ability to screen for malingering in relation to the Bianchini et al. criteria for malingered pain-related disability published in The Spine Journal (2005). Examined brief self-report measures between litigating and nonlitigating pain samples. We compared 144 disability litigants, predominantly presenting a history of musculoskeletal injuries with psychiatric overlay, with 167 nonlitigating pain patients who were predominantly in treatment for chronic back pain issues and other musculoskeletal conditions. Modified Somatic Perception Questionnaire, Pain Disability Index, Minnesota Multiphasic Personality Inventory-2 Restructured Form, Test of Memory Malingering, Letter Memory Test, Victoria Symptom Validity Test, Structured Interview of Reported Symptoms-second edition, Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders somatoform disorders module. We examined a sample of 144 individuals undergoing compensation-seeking evaluations in relation to 167 nonlitigating pain patients. Group differences on both the MSPQ and PDI were calculated, as well as sensitivities, specificities, and positive and negative predictive powers for both measures at selected cutoffs. The results suggest that both the MSPQ and PDI are useful to screen for pain malingering in forensic evaluations, especially the MSPQ, which performed the best in differentiating between the groups.

    Landfill leachate generated from open MSW dumpsite can cause groundwater contamination. The impact of open dumping of MSW on the groundwater of adjacent area was studied. To assess the spatial and temporal variations in groundwater quality, samples were collected around an open MSW dumping site in Ranchi city, Jharkhand, India. Groundwater samples were analysed for various physicochemical and bacteriological parameters for 1 year. Results indicated that the groundwater is getting contaminated due to vertical and horizontal migration of landfill leachate. Extent of contamination was higher in areas closer to the landfill as indicated by high alkalinity, total dissolved solids and ammonia concentration. Metals such as lead, iron, and manganese were present at concentrations of 0.097, 0.97 and 0.36 mg/L, respectively exceeding the Bureau of Indian Standards (BIS) 10,500 for drinking water. Enterobacteriaceae were also detected in several groundwater samples and highest coliform count of 2.1×10(4) CFU/mL was recorded from a dug well. In order to determine the overall groundwater quality, water quality index (WQI) was calculated using weighted arithmetic index method and this index was further modified by coupling with the analytical hierarchy process (AHP) to get specific information. WQI values indicated that the overall groundwater quality of the region came under "poor" category while zone wise classification indicated the extent of impact of landfill leachate on groundwater.

    The questionnaire for the assessment of the voice selfconcept (FESS) contains three sub-scales indicating the personal relation with the own voice. The scales address the relationship with one's own voice, the awareness of the use of one's own voice, and the perception of the connection between voice and emotional changes. A comprehensive approach across the three scales supporting a simplified interpretation of the results was still missing. The FESS questionnaire was used in a sample of 536 German teachers. With a discrimination analysis, commonalities in the scale characteristics were investigated. For a comparative validation with voice health and psychological and physiological wellbeing, the Voice Handicap Index (VHI), the questionnaire for Work-related Behavior and Experience Patterns (AVEM), and the questionnaire for Health-related Quality of Life (SF-12) were additionally collected. The analysis provided four different groups of voice self-concept: group 1 with healthy values in the voice self-concept and wellbeing scales, group 2 with a low voice self-concept and mean wellbeing values, group 3 with a high awareness of the voice use and mean wellbeing values and group 4 with low values in all scales. The results show that a combined approach across all scales of the questionnaire for the assessment of the voice self-concept enables a more detailed interpretation of the characteristics in the voice self-concept. The presented groups provide an applicable use supporting medical diagnoses. © Georg Thieme Verlag KG Stuttgart · New York.

    To evaluate the reliability and validity of Chinese version of Quality-of-life assessment Questionnaires for Intermittent Exotropia (CIXTQ). Cross-sectional study. The original English version of the IXTQ was translated into Chinese. The final Chinese version of the IXTQ (CIXTQ) consists of 3 parts: the 12-item child CIXTQ (for children ≥5 and<8 years old and ≥8 and<18 years old, respectively, to assess their health quality of life (HRQoL)), the 12-item proxy CIXTQ (for parents to assess children's HRQoL), and the 17-item parent CIXTQ (containing functional, psychosocial, and surgery subscales; for parents to assess their HRQoL). 175 IXT children and 151 control children along with one of their parents were recruited to answer the CIXTQ. Cronbach's α coefficient and split-half reliability were used to test the internal consistency reliability of the CIXTQ. Kappa coefficient was used to assess the test-retest reliability. Scale-level content validity index/average (S-CVI/Ave) was used to evaluate the content validity of the CIXTQ. Principal component analysis (PCA) was used to verify the construct validity of the parent CIXTQ. Comparison of different CIXTQ scores in IXT patients with controls was conducted by independent-samples t test to evaluate the discriminate validity of the CIXTQ. For all scales and subscales of the CIXTQ in different age groups, the Cronbach's α ranged from 0.804 to 0.963; the split-half reliability ranged from 0.658 to 0.963 and was higher than 0.7 except for the proxy CIXTQ for children aged ≥5 and<8 years old; the test-retest reliability ranged from 0.569 to 0.944. The S-CVI/Ave of the child, proxy and parent CIXTQ was 0.988, 0.988 and 0.966, respectively. Principal factors identified by PCA for the parent CIXTQ could be regrouped into the originally described 3 subscales which was functional, social psychology and surgery in different age groups.

    The objectives of the study were to translate, validate, and verify the psychometric properties of the Portuguese version of the instrument "Pediatric Quality of Life Asthma Module" (PedsQL Asthma) culturally adapted for the Brazilian culture. After being translated to Portuguese and being culturally adapted, the questionnaire was answered by 200 asthmatic children and adolescents (aged 2-18) as well as the adults responsible for them. Validation required the use of the following instruments: PedsQL Asthma Children (applied to children and adolescents), PedsQL Asthma Parents (applied to adults responsible for children and adolescents), Pediatric Asthma Quality of Life (PAQLQ), Asthma Control Test (ACT) or Childhood Asthma Control Test (C-ACT), as well as socioeconomic and personal information questionnaires. A group of 45 clinically stable children repeated the questionnaires 15-60 days after answering the first questionnaire. Correlations between the scores of PedsQL Children and PedsQL Parents (r  =  0.67), PedsQL Children and PAQLQ (r  =  0.66), and PedsQL Parents and PAQLQ (r  =  0.64) were moderate and significant. Correlations were higher for men (r  =  0.72) when analyzing the children's and parents' answers to PedsQL according to gender. The 5- to 7-year-old age group had the strongest correlations with PAQLQ (r  =  0.79). Cronbach's alpha coefficient for PedsQL Children and Parents had values of 0.85 and 0.87, respectively. A high concordance was observed in both tests at different times, with kappa values of 0.89 and 0.87 for PedsQL Children and Parents, respectively. The instrument used in this study was considered valid, consistent, and reproducible and has acceptable psychometric properties for the Brazilian population.

    Sleep and epilepsy share a complex pathophysiological association. Juvenile myoclonic epilepsy (JME) is a common sleep-sensitive epilepsy in which the effect of seizures could have therapeutic implications in terms of sleep disturbances and seizure control. This study aimed to analyze the effect of epilepsy on sleep in patients with JME. Fifty patients on valproic acid (VPA) monotherapy, and age- and gender-matched controls were recruited into this prospective, hospital-based, case-control study after informed consent and screening for inclusion criteria. They underwent a detailed clinical assessment, electroencephalogram (EEG) and neuroimaging, and were administered validated sleep questionnaires, which included the Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI) and NIMHANS Sleep Disorders Questionnaire. The patient and control groups had identical numbers of males and females (M: F=22: 28), without any significant difference in the age and body mass index (BMI). The clinical profile of JME was similar to published literature while the prevalence of EEG abnormalities was less compared to similar studies. The mean ESS and PSQI scores and the number of subjects with abnormal scores on one or both questionnaires were significantly more in patients. Patients had a higher prevalence of sleep disturbances, insomnia and excessive daytime somnolence. No significant seizure- or treatment-related factors influencing sleep could be identified. This study, the first of its kind, revealed that patients with JME have significant sleep disturbances characterized by excessive daytime sleepiness and disturbed night sleep, despite adequate medications and good seizure control. The role of VPA in the genesis of these symptoms needs clarification. Copyright © 2012 Elsevier Inc. All rights reserved.

    Objective:: To evaluate the quality of life (QOL) of parents of children with asthma and to analyze the internal consistency of the generic QOL tool World Health Organization Quality of Life, abbreviated version (WHOQOL-BREF). Methods:: We evaluated the QOL of parents of asthmatic and healthy children aged between 8 and 16, using the generic WHOQOL-BREF questionnaire. We also evaluated the internal consistency using Cronbach's alpha (αC), in order to determine whether the tool had good validity for the target audience. Results:: The study included 162 individuals with a mean age of 43.8±13.6 years, of which 104 were female (64.2%) and 128 were married (79.0%). When assessing the QOL, the group of parents of healthy children had higher scores than the group of parents of asthmatic children in the four areas evaluated by the questionnaire (Physical, Psychological Health, Social Relationships and Environment), indicating a better quality of life. Regarding the internal consistency of the WHOQOL-BREF, values of ˛C were 0.86 points for the group of parents of asthmatic children, and 0.88 for the group of parents of healthy children. Conclusions:: Parents of children with asthma have impaired quality of life due to their children's disease. Furthermore, the WHOQOL-BREF, even as a generic tool, showed to be practical and efficient to evaluate the quality of life of parents of asthmatic children. © 2015 Sociedade de Pediatria de São Paulo.

    The aim of this study was to evaluate the associations between chronic inflammatory skin conditions and patients' emotional state and quality of life. The following self-rated questionnaires were used: Emotional State Questionnaire, a self-report scale assessing depression and anxiety symptoms; Dermatology Life Quality Index (DLQI); and RAND-36, a measure of health-related quality of life. The study group comprised 40 patients with psoriasis, 40 with eczema, 40 with acne, 15 with seborrhoeic dermatitis and 40 healthy controls. Patients with chronic skin diseases had lower DLQI and lower RAND-36 physical functioning scores, more perceived physical limitations and pain, and lower emotional well-being and general health ratings compared with the control group. In conclusion, chronic skin diseases are associated with symptoms of emotional distress, in particular insomnia and general anxiety.

    Abstract Condyloma acuminata (CA) is a sexually transmitted disease that affects quality of life (QOL). CECA10 is an English-language questionnaire for assessing QOL in patients with CA, but there is no equivalent in China. This study aimed to develop a validated and reliable Chinese version of CECA10. The Chinese CECA10 was developed from the English version by forward translation, back translation, comparison with the original, cultural adjustments, and a pre-test (5 patients). The Chinese CECA10 and EuroQol Five Dimensions Three Level Questionnaire (EQ-5D-3L) was administered to patients with CA. Content validity (item/scale content validity indexes, I-CVI/S-CVI), test–retest reliability (intraclass coefficient, ICC), internal consistency (Cronbach α), criterion validity (comparison with the Dermatology Life Quality Index, DLQL, using Spearman correlation analysis), construct validity (exploratory factor analysis), and discriminant validity (between subgroups based on number of warts, number of recurrences, or number of sites involved) were assessed. The Chinese CECA10 had good test–retest reliability (ICC = 0.98, P < .001), internal consistency (Cronbach α values of 0.88, 0.84, and 0.83 for the total questionnaire, psychological dimension, and sexual dimension, respectively), content validity (I-CVI = 1 for all items), and criterion validity (r = -0.50, P < .001). Exploratory factor analysis extracted 2 factors with a cumulative contribution of 61.75%; the factor loading with each item was >0.4. Discriminant validity was not high. The mean CECA10 and EQ-VAS scores of 211 patients with CA (28.19 ± 7.16 years; 139 males) were 34.56 ± 19.01 and 64.64 ± 19.28, respectively. The Chinese CECA10 has good reliability and validity for evaluating the QOL of Chinese patients with CA. PMID:29489693

    Multidisciplinary clinical research on childhood cancer has achieved a marked improvement in survival rate during the last two decades. Due to the increase of long-term survivors, the survey of quality of life (QOL) of cured children is essential. But methods to estimate QOL of children have not been established. We attempted to estimate the QOL of surviving patients from the responses to a questionnaire filled out by their parents. The total number of patients treated at the National Children's Hospital from 1965-1987 was 937, of which 296 patients are still surviving. Among these survivors 108 patients were selected to be surveyed because they were being followed up by our attending physicians. The originally elaborated questionnaire was sent to parents in June 1989. Seventy-eight parents responded. The questionnaire consisted of four major questions. The first was how the QOL of the child compared to that of an ordinary child. The parents circled the appropriate level of QOL determined by our scale (1 lower, 4 the same as ordinary child, 7 excellent). The average score was 5.61 showing that parents felt their child's QOL is superior to an ordinary child. The second question concerned how the present status of the child was influenced by the experience of cancer. Answers were divided into five categories as follows: 1) Good or positive (10%); 2) nothing in particular (49%); minimum (29%); negative (9%); and other (7%). The third question concerned any anxieties. Most parents had numerous anxieties about the relapse, late effects, education, job prospects, marriage and offspring and getting the latest information. The fourth question dealt with what to tell the child as to their true diagnosis. Answers were divided as follows: absolutely no (56%); yes, but in the future (23%); yes, already done (10%); and yes, through our physician; (13%). After studying the questionnaires we interviewed the parents. We noticed that the parent/child relationship was very close. A

    To translate and test the reliability and validity of the Persian version of the Caregiver Quality of Life Index-Cancer scale. Research across many countries has determined quality of life of cancer patients, but few attempts have been made to measure the quality of life of family caregivers of patients with breast cancer. The Caregiver Quality of Life Index-Cancer scale was developed for this purpose, but until now, it has not been translated into or tested in the Persian language. Methodological research design. After standard translation, the 35-item Caregiver Quality of Life Index-Cancer scale was administered to 166 Iranian family caregivers of patients with breast cancer. A confirmatory factor analysis was carried out using LISREL to test the scale's construct validity. Further, the internal consistency and convergent validity of the instrument were tested. For convergent validity, four instruments were used in the study: sense of coherence scale, spirituality perspective scale, health index and brief religious coping scale. The confirmatory factor analysis resulted in the same four-factor structure as the original, though, with somewhat different item loadings. The Persian version of the Caregiver Quality of Life Index-Cancer scales had satisfactory internal consistency (0·72-0·90). Tests of convergent validity showed that all hypotheses were confirmed. A hierarchical multiple regression analysis additionally confirmed the convergent validity between the total Caregiver Quality of Life Index-Cancer score and sense of coherence (β = 0·34), negative religious coping (β = -0·21), education (β = 0·24) and the more severe stage of breast cancer (β = 0·23), in total explaining 41% of the variance. The Persian version of the Caregiver Quality of Life Index-Cancer scale could be a reliable and valid measure in Iranian family caregivers of patients with breast cancer. The Persian version of the Caregiver Quality of Life Index-Cancer scale is simple to

    To compare the responsiveness to clinical change of five widely used preference-based health-related quality-of-life indexes in two longitudinal cohorts. Five generic instruments were simultaneously administered to 376 adults undergoing cataract surgery and 160 adults in heart failure management programs. Patients were assessed at baseline and reevaluated after 1 and 6 months. The measures were the Short Form (SF)-6D (based on responses scored from SF-36v2), Self-Administered Quality of Well-being Scale (QWB-SA), the EuroQol-5D developed by the EuroQol Group, the Health Utilities Indexes Mark 2 (HUI2) and Mark 3 (HUI3). Cataract patients completed the National Eye Institute Visual Functioning Questionnaire-25, and heart failure patients completed the Minnesota Living with Heart Failure Questionnaire. Responsiveness was estimated by the standardized response mean. For cataract patients, mean changes between baseline and 1-month follow-up for the generic indices ranged from 0.00 (SF-6D) to 0.052 (HUI3) and were statistically significant for all indexes except the SF-6D. For heart failure patients, only the SF-6D showed significant change from baseline to 1 month, whereas only the QWB-SA change was significant between 1 and 6 months. Preference-based methods for measuring health outcomes are not equally responsive to change. Copyright © 2011 Elsevier Inc. All rights reserved.

    To analyze the reliability and validity of the Spanish version of the OSA-18 quality of life questionnaire in children with apnea-hypopnea syndrome (SAHS). Children with suspected SAHS were studied with polysomnography (PSG) before and after adenotonsillectomy (AA). Age, gender, clinical data, PSG, anthropometric data, and Mallampati and Brodsky scales were analyzed. OSA-18 was administered at baseline and 3-6months post AA. After translation and backtranslation by bilingual professionals, the internal consistency, reliability, construct validity, concurrent validity, predictive validity and sensitivity to change of the questionnaire was assessed. In total, 45 boys and 15 girls were evaluated, showing BMI 18±4, neck 28±5, Brodsky (0: 7%; <25%: 12%; 25-50%: 27%; >50 to <75%: 45%; >75%: 6%), AHI 12±7 pre AA. Global Cronbach alpha was 0.91. Correlations between domains were significant except for emotional aspects, although the total scores correlated with all domains (0.50 to 0.90). The factorial analysis was virtually identical to the original structure. The total scores showed good correlation for concurrent validity (0.2-0.45). With regard to predictive validity, the questionnaire adequately differentiated levels of severity according to Mallampati (ANOVA P=.002) and apnea-hypopnea index (ANOVA P=.006). Test-retest reliability was excellent, as was sensitivity to change, both in the total scores (P<.001) and in each domain (P<.001). The Spanish adaptation of the OSA-18 and its psychometric characteristics suggest that the Spanish version is equivalent to the original and can be used in Spanish-speaking countries.

    The number of studies comparing nutritional quality of restrictive diets is limited. Data on vegan subjects are especially lacking. It was the aim of the present study to compare the quality and the contributing components of vegan, vegetarian, semi-vegetarian, pesco-vegetarian and omnivorous diets. Dietary intake was estimated using a cross-sectional online survey with a 52-items food frequency questionnaire (FFQ). Healthy Eating Index 2010 (HEI-2010) and the Mediterranean Diet Score (MDS) were calculated as indicators for diet quality. After analysis of the diet questionnaire and the FFQ, 1475 participants were classified as vegans (n = 104), vegetarians (n = 573), semi-vegetarians (n = 498), pesco-vegetarians (n = 145), and omnivores (n = 155). The most restricted diet, i.e., the vegan diet, had the lowest total energy intake, better fat intake profile, lowest protein and highest dietary fiber intake in contrast to the omnivorous diet. Calcium intake was lowest for the vegans and below national dietary recommendations. The vegan diet received the highest index values and the omnivorous the lowest for HEI-2010 and MDS. Typical aspects of a vegan diet (high fruit and vegetable intake, low sodium intake, and low intake of saturated fat) contributed substantially to the total score, independent of the indexing system used. The score for the more prudent diets (vegetarians, semi-vegetarians and pesco-vegetarians) differed as a function of the used indexing system but they were mostly better in terms of nutrient quality than the omnivores.

    The number of studies comparing nutritional quality of restrictive diets is limited. Data on vegan subjects are especially lacking. It was the aim of the present study to compare the quality and the contributing components of vegan, vegetarian, semi-vegetarian, pesco-vegetarian and omnivorous diets. Dietary intake was estimated using a cross-sectional online survey with a 52-items food frequency questionnaire (FFQ). Healthy Eating Index 2010 (HEI-2010) and the Mediterranean Diet Score (MDS) were calculated as indicators for diet quality. After analysis of the diet questionnaire and the FFQ, 1475 participants were classified as vegans (n = 104), vegetarians (n = 573), semi-vegetarians (n = 498), pesco-vegetarians (n = 145), and omnivores (n = 155). The most restricted diet, i.e., the vegan diet, had the lowest total energy intake, better fat intake profile, lowest protein and highest dietary fiber intake in contrast to the omnivorous diet. Calcium intake was lowest for the vegans and below national dietary recommendations. The vegan diet received the highest index values and the omnivorous the lowest for HEI-2010 and MDS. Typical aspects of a vegan diet (high fruit and vegetable intake, low sodium intake, and low intake of saturated fat) contributed substantially to the total score, independent of the indexing system used. The score for the more prudent diets (vegetarians, semi-vegetarians and pesco-vegetarians) differed as a function of the used indexing system but they were mostly better in terms of nutrient quality than the omnivores.

    Objectives To develop the Chinese version of the Polycystic Ovary Syndrome Health-related Quality of Life Questionnaire (Chi-PCOSQ). Research Design and Method This cross-sectional study was conducted in a medical center in Taiwan. Eighty women who met the criteria were enrolled: female, age range of 18–45 years, competent in the Chinese language, had been diagnosed with polycystic ovary syndrome (PCOS), and were regularly followed at outpatient clinics (defined as at least two outpatient visits before enrollment). The PCOSQ was translated and culturally adapted according to standard procedures. A semi-structured interview was applied to assess face validity. Exploratory factor analysis (EFA) was applied to determine scale constructs. Measurements of internal consistency via Cronbach’s α, test-retest reliability via intraclass correlation coefficient (ICC), construct validity, and discriminative validity were performed. Results Five additional items, representing the issues of acne, hair loss, and fear of getting diabetes, were incorporated into the original scale. A six-factor structure emerged as a result of the EFA, explaining 71.9% of the variance observed. The reliability analyses demonstrated satisfactory results for Cronbach’s α ranging from 0.78–0.96, and for ICC ranging from 0.73–0.86. Construct validity was confirmed by significant correlation between the domains of the Chi-PCOSQ and generic health-related quality of life (HRQoL) measures (WHOQOL-BREF, EQ-5D) and clinical parameters (body mass index, waist-hip ratio, blood pressure). The known-group analysis indicated that the Chi-PCOSQ is a discriminative tool that differentiates patients according to their HRQoL. Conclusion The Chi-PCOSQ seems internally consistent, culturally acceptable, and our preliminary evidence suggests that it may be reliable and valid. The Chi-PCOSQ is a promising assessment tool to address the HRQoL of women affected by PCOS in Chinese-speaking countries and to

    The Intermittent Exotropia Questionnaire (IXTQ) is a patient, proxy, and parental report of quality of life specific to children with intermittent exotropia. We refine the IXTQ using Rasch analysis to improve reliability and validity. Rasch analysis was performed on responses of 575 patients with intermittent exotropia enrolled from May 15, 2008, through July 24, 2013, and their parents from each of the 4 IXTQ health-related quality-of-life questionnaires (child 5 through 7 years of age and child 8 through 17 years of age, proxy, and parent questionnaires). Questionnaire performance and structure were confirmed in a separate cohort of 379 patients with intermittent exotropia. One item was removed from the 12-item child and proxy questionnaires, and response options in the 8- to 17-year-old child IXTQ and proxy IXTQ were combined into 3 response options for both questionnaires. Targeting was relatively poor for the child and proxy questionnaires. For the parent questionnaire, 3 subscales (psychosocial, function, and surgery) were evident. One item was removed from the psychosocial subscale. Resulting subscales had appropriate targeting. The Rasch-revised IXTQ may be a useful instrument for determining how intermittent exotropia affects health-related quality of life of children with intermittent exotropia and their parents, particularly for cohort studies.

    Objective Obesity and its comorbidities have emerged as a leading public health concern. Our aim was to explore the relationship between BMI and sleep patterns, including duration and disturbances. Methods A convenience sample of 515 college students completed an online survey consisting of the Pittsburgh Sleep Quality Index (PSQI), and self-reported height and weight to calculate Body Mass Index (BMI). Univariate and multivariate logistic regression analyses were performed using components of the PSQI as predictors of overweight (BMI ≥ 25). Results One-third of the participants had BMI ≥ 25, and 51% were poor-quality sleepers (PSQI > 5). Controlling for age and sex, only sleep disturbances were associated to overweight (OR=1.66, 95% CI: 1.08-2.57). Conclusions Sleep disturbances, rather than sleep duration predicted overweight among young adults; this is consistent with the most recent evidence in the literature. These findings support expanding the scope of wellness programs to promote healthy sleep among students. PMID:24933244

    Objective To assess whether there is a relationship between having quality as an item on the board's agenda, perceived external pressure (PEP) and the implementation of quality management in European hospitals. Design A quantitative, mixed method, cross-sectional study in seven European countries in 2011 surveying CEOs and quality managers and data from onsite audits. Participants One hundred and fifty-five CEOs and 155 quality managers. Setting One hundred and fifty-five randomly selected acute care hospitals in seven European countries (Czech Republic, France, Germany, Poland, Portugal, Spain and Turkey). Main outcome measure(s) Three constructs reflecting quality management based on questionnaire and audit data: (i) Quality Management System Index, (ii) Quality Management Compliance Index and (iii) Clinical Quality Implementation Index. The main predictor was whether quality performance was on the executive board's agenda. Results Discussing quality performance at executive board meetings more often was associated with a higher quality management system score (regression coefficient b = 2.53; SE = 1.16; P = 0.030). We found a trend in the associations of discussing quality performance with quality compliance and clinical quality implementation. PEP did not modify these relationships. Conclusions Having quality as an item on the executive board's agenda allows them to review and discuss quality performance more often in order to improve their hospital's quality management. Generally, and as this study found, having quality on the executive board's agenda matters. PMID:24550260

    The objective was to develop an index based on the Dutch Guidelines for a healthy Diet of 2006 that reflects dietary quality and to apply it to the Dutch National Food Consumption Survey (DNFCS) to examine the associations with micronutrient intakes. A total of 749 men and women, aged 19-30 years, contributed two 24-hour recalls and additional questionnaires in the DNFCS of 2003. The Dutch Healthy Diet index (DHD-index) includes ten components representing the ten Dutch Guidelines for a Healthy Diet. Per component the score ranges between zero and ten, resulting in a total score between zero (no adherence) and 100 (complete adherence). The mean ± SD of the DHD-index was 60.4 ± 11.5 for women and 57.8 ± 10.8 for men (P for difference = 0.002). Each component score increased across the sex-specific quintiles of the DHD-index. An inverse association was observed between the sex-specific quintiles of the DHD-index and total energy intake. Calcium, riboflavin, and vitamin E intake decreased with increasing DHD-index, an inverse association which disappeared after energy adjustment. Vitamin C showed a positive association across quintiles, also when adjusted for energy. For folate, iron, magnesium, potassium, thiamin, and vitamin B6 a positive association emerged after adjustment for energy. The DHD-index is capable of ranking participants according to their adherence to the Dutch Guidelines for a Healthy Diet by reflecting variation in nine out of ten components that constitute the index when based on two 24-hour recalls. Furthermore, the index showed to be a good measure of nutrient density of diets.

    Large datasets from total and dissolved metal concentrations in Flemish (Belgium) fresh water systems and the associated macroinvertebrate-based biotic index MMIF (Multimetric Macroinvertebrate Index Flanders) were used to estimate critical metal concentrations for good ecological water quality, as imposed by the European Water Framework Directive (2000). The contribution of different stressors (metals and water characteristics) to the MMIF were studied by constructing generalized linear mixed effect models. Comparison between estimated critical concentrations and the European and Flemish EQS, shows that the EQS for As, Cd, Cu and Zn seem to be sufficient to reach a good ecological quality status as expressed by the invertebrate-based biotic index. In contrast, the EQS for Cr, Hg and Pb are higher than the estimated critical concentrations, which suggests that when environmental concentrations are at the same level as the EQS a good quality status might not be reached. The construction of mixed models that included metal concentrations in their structure did not lead to a significant outcome. However, mixed models showed the primary importance of water characteristics (oxygen level, temperature, ammonium concentration and conductivity) for the MMIF. Copyright © 2014 Elsevier Ltd.

    The aims are to assess respiration-related quality of life using the St. George Respiratory Questionnaire and determine its influencing factors among patients with silicosis in China. The incidence of silicosis had an increasing trend in recent years in developing countries. Although the majority of patients with silicosis are in therapy routinely, the patients' quality of life has been impaired because silicosis cannot be cured. The study on quality of life of patients with silicosis is few, and clinical physicians have difficulty in planning to promote quality of life of patients with silicosis according to the current health situation. A cross-sectional design was used for this study. A survey was performed on patients with silicosis by face-to-face interview in the Shenyang No. 9 Hospital in China. The St. George Respiratory Questionnaire was used to assess respiration-related quality of life. In all 208 enrolled patients with silicosis, symptoms, activity and impacts scores were 56·02, 56·46 and 52·33, respectively. Lower impacts scores were found comparing with symptoms and activity ones. Patient age was associated with an expected decrease in respiration-related quality of life. Patients with longer duration of exposure had higher total scores of the St. George Respiratory Questionnaire, indicating worse quality of life. Patients with more co-morbidities reported worse quality of life. Patients with silicosis were found relatively moderate respiration-related quality of life. Shortening dust exposure, decreasing the number of co-morbidity and controlling the occurrence of pulmonary tuberculosis could improve respiration-related quality of life. As indicated by the results of this study, the number of co-morbidity negatively impact the quality of life of patients with silicosis. Clinical physicians and nurses should pay close attention to the co-morbidity to promote quality of life of patients with silicosis according to the current health situation.

    To determine the quality of prescribing in hypertension in primary and secondary health care settings using the Prescription Quality Index (PQI) tool and to assess the reliability of this tool. An observational cross-sectional study was carried out for 6 months in order to assess quality of prescribing of antihypertensive drugs using Prescription Quality Index (PQI) at four primary (PHC) and two secondary (SHC) health care facilities. Patients attending these facilities for at least 3 months were included. Complete medical history and prescriptions received were noted. Total and criteria wise PQI scores were derived for each prescription. Prescriptions were categorized as poor (score of ≤31), medium (score 32-33) and high quality (score 34-43) based on PQI total score. Psychometric analysis using factor analysis was carried out to assess reliability and validity. Total 73 hypertensive patients were included. Mean age was 61.2 ± 11 years with 35 (48%) patients above 65 years of age. Total PQI score was 26 ± 11. There was a significant difference in PQI score between PHC and SHC (P < 0.05) Out of 73 prescriptions, 43 (59%) were of poor quality with PQI score <31. The value of Cronbach's α for the entire 22 criteria of PQI was 0.71 suggesting good reliability of PQI tool in our setting. Based on PQI scores, quality of prescribing in hypertensive patients was poor, somewhat better in primary as compared to secondary health care facility. PQI is reliable for measuring prescribing quality in hypertension in Indian set up.

    Essential tremor (ET) can diminish functioning and quality of life (QOL) but generic QOL measures may be relatively insensitive to ET and its therapies. We sought to develop an ET-specific measure that might be more sensitive, acceptable to patients, relatively brief, and easily used. A sample of 200 patients (average age 70 years, range 30-91; average disease duration 15 years) rated the extent to which tremor impacts a function or state, tremor severity in various body parts, perceived health, and overall QOL. Responses to this initial questionnaire were subjected to principal components analysis (PCA). Inspection of factor coordinates, Eigenvalues, variance accounted for, and correlation matrices were used to select items for confirmatory PCA. Final scale reliability was assessed using Cronbach's alpha. Validity was evaluated by correlations between QOL scales and self-rated tremor severity. PCA of 65 initial items yielded 11 factors accounting for 71% of variance. Six factors were discarded. Two items were eliminated for not loading on a factor and 33 for perceived redundancy. Confirmatory PCA of the retained 30 items yielded an almost identical factor structure (six factors, 70% of variance accounted for, and similar item loadings). Because two factors had very few items loading on them, these two factors were combined into one scale. The final measure has five scales: Physical, Psychosocial, Communication, Hobbies/Leisure, and Work/Finance. Reliability was excellent for the whole instrument and four scales (> or =0.89), and good for the Work/Finance scale (0.79). Severity of voice and head tremor were the best correlates of Communication (0.70 and 0.35), while the Physical scale was related to right and left upper extremity tremor (0.59 and 0.56). Scales correlated more highly with patients' rating of their overall QOL than their health perception. A brief, 30-item, ET-specific QOL scale with excellent reliability was developed. Preliminary validity data are

    The revised version of the Fibromyalgia Impact Questionnaire (FIQR) is one of the most widely used specific questionnaires in FM studies. However, this questionnaire does not allow calculation of QALYs as it is not a preference-based measure. The aim of this study was to develop mapping algorithm which enable FIQR scores to be transformed into utility scores that can be used in the cost utility analyses. A cross-sectional survey was conducted. One hundred and 92 Spanish women with Fibromyalgia were asked to complete four general quality of life questionnaires, i.e. EQ-5D-5 L, 15D, AQoL-8D and SF-12, and one specific disease instrument, the FIQR. A direct mapping approach was adopted to derive mapping algorithms between the FIQR and each of the four multi-attribute utility (MAU) instruments. Health state utility was treated as the dependent variable in the regression analysis, whilst the FIQR score and age were predictors. The mean utility scores ranged from 0.47 (AQoL-8D) to 0.69 (15D). All correlations between the FIQR total score and MAU instruments utility scores were highly significant (p < 0.0001) with magnitudes larger than 0.5. Although very slight differences in the mean absolute error were found between ordinary least squares (OLS) estimator and generalized linear model (GLM), models based on GLM were better for EQ-5D-5 L, AQoL-8D and 15D. Mapping algorithms developed in this study enable the estimation of utility values from scores in a fibromyalgia specific questionnaire.

    The Medical Subject Headings (MeSH) is the National Library of Medicine (NLM) controlled vocabulary for indexing articles. Inaccuracies in the MeSH thesaurus have been reported for several areas including pharmacy. To assess the quality of pharmacy-specific MeSH assignment to articles indexed in pharmacy journals. The 10 journals containing the highest number of articles published in 2012 indexed under the MeSH 'Pharmacists' were identified. All articles published over a 5-year period (2008-2012) in the 10 previously selected journals were retrieved from PubMed. MeSH terms used to index these articles were extracted and pharmacy-specific MeSH terms were identified. The frequency of use of pharmacy-specific MeSH terms was calculated across journals. A total of 6989 articles were retrieved from the 10 pharmacy journals, of which 328 (4.7%) were articles not fully indexed and therefore did not contain any MeSH terms assigned. Among the 6661 articles fully indexed, the mean number of MeSH terms was 10.1 (SD = 4.0), being 1.0 (SD = 1.3) considered as Major MeSH. Both values significantly varied across journals. The mean number of pharmacy-specific MeSH terms per article was 0.9 (SD = 1.2). A total of 3490 (52.4%) of the 6661 articles were indexed in pharmacy journals without a single pharmacy-specific MeSH. Of the total 67193 MeSH terms assigned to articles, on average 10.5% (SD = 13.9) were pharmacy-specific MeSH. A statistically significant different pattern of pharmacy-specific MeSH assignment was identified across journals (Kruskal-Wallis P < 0.001). The quality of assignment of the existing pharmacy-specific MeSH terms to articles indexed in pharmacy journals can be improved to further enhance evidence gathering in pharmacy. Over half of the articles published in the top-10 journals publishing pharmacy literature were indexed without a single pharmacy-specific MeSH. Copyright © 2015 Elsevier Inc. All rights reserved.

    In clinical outcome assessment, the relation between performance-based measures and questionnaire ratings of the same domain is weak, but correlations between questionnaires proposed for the evaluation of different domains are strong. The present study aims to illustrate these phenomena in a group of patients with neurofibromatosis type 1 (NF1) and to propose an explanatory hypothesis. A single neuropsychologist interviewed the parents about the child's situation and current difficulties and then assessed this parental view as overall positive or overall negative. The same assessor then administered the Wechsler Intelligence Scales and neuropsychological tests to 78 children and adolescents with NF1 (5-18 years). Parents then completed the Child Behavioral Checklist (CBCL), the Conners' Parent Rating Scale, the Behavior Rating Inventory of Executive Function (BRIEF), as well as questionnaires assessing quality of life, impact of the medical disorder, and their own difficulties. All questionnaires were inter-correlated (r = 0.29 - 0.84) and associated with the overall positive or negative parental view of the child's progress (effect size = 0.41-1.46). Conversely, questionnaires were weakly or not significantly related to intelligence, cognitive measures, or clinical severity. In conclusion, the parental view of the child's progress was related to the answers to questionnaires assessing quality of life or strengths and difficulties of patients with a neurological disorder. This factor should be assessed independently and taken into account when assessing clinical outcome.

    There is a need for well-developed and validated questionnaires to measure patient reported outcomes. The Quality of Life in Hand Eczema Questionnaire (QOLHEQ) is such a validated instrument measuring disease-specific health-related quality of life in hand eczema patients. A re-validation of measurement properties is required before an instrument is used in a new population. With the objective of arriving at a guideline for translation and national validation of the QOLHEQ, we have developed the design of a reference study on how to adequately assess measurement properties of the QOLHEQ based on interdisciplinary discussions and current standards. We present a step-by-step guideline to assess translation (including cross-cultural adaptation), scale structure, validity, reproducibility, responsiveness, and interpretability. We describe which outcomes should be reported for each measurement property, and give advice on how to calculate these. It is also specified which sample size is needed, how to deal with missing data, and which cutoff values should be applied for the measurement properties assessed during the validation process. In conclusion, this guideline, presenting a reference validation study for the QOLHEQ, creates the possibility to harmonize the national validation of the various language versions of the QOLHEQ. © 2017 John Wiley & Sons A/S.

    Background Patient-reported health-related quality of life is increasingly used as an outcome measure in clinical trials and as a performance measure to evaluate quality of care. The objective of this study was to assess the psychometric properties of the Danish HeartQoL questionnaire, a core heart disease-specific health-related quality of life questionnaire, in implantable cardioverter defibrillator recipients. Design This study involved cross-sectional and test-retest study designs. Method Implantable cardioverter defibrillator recipients in the cross-sectional study completed the HeartQoL, the Short-Form 36 Health Survey, and the Hospital Anxiety and Depression Scale. The HeartQoL structure, construct-related validity (convergent and discriminative) and reliability (internal consistency) were assessed. HeartQoL reproducibility (test-retest) was assessed in an independent sample of implantable cardioverter defibrillator recipients. Results Mokken scale analysis supported the bi-dimensional structure of HeartQoL among 358 implantable cardioverter defibrillator recipients. Convergent ( r > 0.72) and discriminative validity were confirmed. The HeartQoL scales demonstrated satisfactory internal consistency (Cronbach's alpha > 0.90). Test-retest reliability (two weeks interval) was assessed in 89 implantable cardioverter defibrillator recipients and found to be acceptable for each scale (intra-class correlation > 0.90). Conclusion The Danish HeartQoL questionnaire demonstrated satisfactory key psychometric attributes of validity and reliability in this implantable cardioverter defibrillator population. This study adds support for the HeartQoL as a core heart-specific health-related quality of life questionnaire in a broad group of patients with heart disease including implantable cardioverter defibrillator recipients.

    A prospective clinical study to test and adapt a Finnish version of the Scoliosis Research Society 30 (SRS-30) questionnaire. The aim of this study was to perform cross-cultural adaptation and evaluate the validity of the adapted Finnish version of the SRS-30 questionnaire. The SRS-30 questionnaire has proved to be a valid instrument in evaluating health-related quality of life (HRQoL) in adolescent and adult population with spine deformities in the United States. Multinational availability requires cross-cultural and linguistic adaptation and validation of the instrument. The SRS-30 was translated into Finnish using accepted methods for translation of quality-of-life questionnaires. A total of 274 adult patients with degenerative radiographic sagittal spinal disorder answered the questionnaire with sociodemographic data, RAND 36-item health survey questionnaire (RAND Corp. Health, Santa Monica, CA, US), Oswestry disability index, DEPS depression scale, and Visual Analog Scale (VAS) back and leg pain scales within 2 weeks' interval. The cohort included patients with and without previous spine surgery. Internal consistency and validity were tested with Cronbach α, intraclass correlation (ICC), standard error of measurement, and Spearman correlation coefficient with 95% confidence intervals (CIs). The internal consistency of SRS-30 was good in both surgery and nonsurgery groups, with Cronbach α 0.853 (95% CI, 0.670 to 0.960) and 0.885 (95% CI, 0.854 to 0.911), respectively. The test-retest reproducibility ICC of the SRS-30 total and subscore domains of patients with stable symptoms was 0.905 (95% CI, 0.870-0.930) and 0.904 (95% CI, 0.871-0.929), respectively. The questionnaire had discriminative validity in the pain, self-image, and satisfaction with management domains compared with other questionnaires. The SRS-30 questionnaire proved to be valid and applicable in evaluating HRQoL in Finnish adult spinal deformity patients. It has two domains related to deformity

    The Mini Asthma Quality of Life Questionnaire (MiniAQLQ) is a validated disease-specific quality of life (QOL) paper (p) questionnaire. Electronic (e) versions enable inclusion of asthma QOL in electronic medical records and research databases. To validate an e-version of the MiniAQLQ, compare time required for completion of e- and p-versions, and determine which version participants prefer. Adults with stable asthma were randomized to complete either the e- or p-MiniAQLQ, followed by a 2-h rest period before completing the other version. Agreement between versions was measured using the intraclass correlation coefficient (ICC) and Bland-Altman analysis. Two participants with incomplete p-MiniAQLQ responses were excluded. Forty participants (85% female; age 47.7 +/- 14.9 years; asthma duration 22.6 +/- 16.1 years; FEV(1) 87.1 +/- 21.6% predicted) with both AQLQ scores <6.0 completed the study. Agreement between e- and p-versions for the overall score was acceptable (ICC=0.95) with no bias (difference (Delta) p-e=0.1; P=0.21). ICCs for the symptom, activity limitation, emotional function and environmental stimuli domains were 0.94, 0.89, 0.90, and 0.91 respectively. A small but significant bias (Delta=0.3; P=0.004) was noted in the activity limitation domain. Completion time was significantly longer for the e-version (3.8 +/- 1.9min versus 2.7 +/- 1.1min; P<0.0001). The majority of patients (57.5%) preferred the e-MiniAQLQ; 35% had no preference. This e-version of the MiniAQLQ is valid and was preferred by most participants despite taking slightly longer to complete. Generalizabilty may be limited in younger (12-17) and older (>65) adults.

    The European Organisation for Research and Treatment of Cancer quality of life (EORTC QL) questionnaires are used in international trials and therefore standardised translation procedures are required. This report summarises the EORTC translation procedure, recent accomplishments and challenges. Translations follow a forward-backward procedure, independently carried out by two native-speakers of the target language. Discrepancies are arbitrated by a third consultant, and solutions are reached by consensus. Translated questionnaires undergo a pilot-testing. Suggestions are incorporated into the final questionnaire. Requests for translations originate from the module developers, physicians or pharmaceutical industry, and most translations are performed by professional translators. The translation procedure is managed and supervised by a Translation Coordinator within the EORTC QL Unit in Brussels. To date, the EORTC QLQ-C30 has been translated and validated into more than 60 languages, with further translations in progress. Translations include all major Western, and many African and Asian languages. The following translation problems were encountered: lack of expressions for specific symptoms in various languages, the use of old-fashioned language, recent spelling reforms in several European countries and different priorities of social issues between Western and Eastern cultures. The EORTC measurement system is now registered for use in over 9000 clinical trials worldwide. The EORTC provides strong infrastructure and quality control to produce robust translated questionnaires. Nevertheless, translation problems have been identified. The key to improvements may lie in the particular features and strengths of the group, consisting of researchers from 21 countries representing 25 languages and include the development of simple source versions, the use of advanced computerised tools, rigorous pilot-testing, certification procedures and insights from a unique cross

    Assessment of management-induced changes in soil quality is important to sustaining high crop yield. A large diversity of cultivated soils necessitate identification development of an appropriate soil quality index (SQI) based on relative soil properties and crop yield. Whereas numerous attempts have been made to estimate SQI for major soils across the World, there is no standard method established and thus, a strong need exists for developing a user-friendly and credible SQI through comparison of various available methods. Therefore, the objective of this article is to compare three widely used methods to estimate SQI using the data collected from 72 soil samples from three on-farm study sites in Ohio. Additionally, challenge lies in establishing a correlation between crop yield versus SQI calculated either depth wise or in combination of soil layers as standard methodology is not yet available and was not given much attention to date. Predominant soils of the study included one organic (Mc), and two mineral (CrB, Ko) soils. Three methods used to estimate SQI were: (i) simple additive SQI (SQI-1), (ii) weighted additive SQI (SQI-2), and (iii) statistically modeled SQI (SQI-3) based on principal component analysis (PCA). The SQI varied between treatments and soil types and ranged between 0–0.9 (1 being the maximum SQI). In general, SQIs did not significantly differ at depths under any method suggesting that soil quality did not significantly differ for different depths at the studied sites. Additionally, data indicate that SQI-3 was most strongly correlated with crop yield, the correlation coefficient ranged between 0.74–0.78. All three SQIs were significantly correlated (r = 0.92–0.97) to each other and with crop yield (r = 0.65–0.79). Separate analyses by crop variety revealed that correlation was low indicating that some key aspects of soil quality related to crop response are important requirements for estimating SQI.

    India has one of the largest assemblages of tropical biodiversity, with its unique floristic composition of endemic species. However, current forest cover assessment is performed via satellite-based forest surveys, which have many limitations. The present study, which was performed in the Eastern Ghats, analysed the satellite-based inventory provided by forest surveys and inferred from the results that this process no longer provides adequate information for quantifying forest degradation in an empirical manner. The study analysed 21 soil properties and generated a forest soil quality index of the Eastern Ghats, using principal component analysis. Using matrix modules and geospatial technology, we compared the forest degradation status calculated from satellite-based forest surveys with the degradation status calculated from the forest soil quality index. The Forest Survey of India classified about 1.8% of the Eastern Ghats’ total area as degraded forests and the remainder (98.2%) as open, dense, and very dense forests, whereas the soil quality index results found that about 42.4% of the total area is degraded, with the remainder (57.6%) being non-degraded. Our ground truth verification analyses indicate that the forest soil quality index along with the forest cover density data from the Forest Survey of India are ideal tools for evaluating forest degradation.

    Background: Multiple diet quality scores have been used to evaluate adherence to specific dietary recommendations or to consumption of healthful foods and nutrients. It remains unknown which score can more strongly predict longitudinal changes in cardiometabolic risk factors. Objective: We aimed to determine associations of 5 diet quality scores [AHA diet score (AHA-DS), Dietary Approaches to Stop Hypertension (DASH), Healthy Eating Index (HEI)-2005, Mediterranean diet score (MeDS), and Alternative Healthy Eating Index (AHEI)] with 2-y changes in cardiometabolic risk factors in adults 45-75 y old. Methods: Data from the Boston Puerto Rican Health Study were analyzed ( n = 1194). Diet quality scores were calculated from a baseline-validated food-frequency questionnaire. Multivariable-adjusted, repeated-subjects, mixed-effects models, adjusted for baseline measures, estimated associations between each z score and 14 individual cardiometabolic factors measured at 2 y. Results: MeDS was significantly associated with lower 2-y waist circumference (β coefficient ± SE: -0.52 ± 0.26, P = 0.048); body mass index (BMI; -0.23 ± 0.08, P = 0.005); log-insulin (-0.06 ± 0.02, P = 0.005); log-homeostasis model assessment of insulin resistance (HOMA-IR; -0.05 ± 0.02, P = 0.030), and log-C-reactive protein (-0.13 ± 0.03, P = 0.0002). Similar but weaker associations were observed for the AHEI with BMI, insulin, and HOMA-IR. The AHA-DS was inversely associated with BMI (-0.17 ± 0.08, P = 0.033). Neither the HEI-2005 nor DASH was significantly associated with any variable. Traditional Puerto Rican foods consumed by individuals with high MeDSs included vegetables and meats in homemade soups, orange juice, oatmeal, beans and legumes, fish, whole milk, corn oil, and beer. Conclusions: The MeDS comprises food components and scores associated with a favorable cardiometabolic profile over 2 y in Puerto Rican adults. An overall healthy diet may be particularly beneficial for

    To analyze the contents and formats of general self-reported questionnaires on disability that are designed for and/or are widely applied in the elderly population to depict a complete picture of this field and help researchers to choose proper tools more efficiently. A broad systematic literature search was performed in September 2013 and included the following databases: MEDLINE, EMBASE, CINAHL, PsycINFO, and PROQOLID. The publication language was limited to English and Chinese. Two review authors independently performed the study selection and data extraction. All of the included instruments were extracted and classified using the International Classification of Functioning, Disability, and Health framework. Of 5569 articles retrieved from the searches and 156 articles retrieved from the pearling, 22 studies (including 24 questionnaires) fulfilled the inclusion criteria. From these, 42 different domains and 458 items were extracted. The most frequently used questionnaire was the Barthel Index followed by the Lawton and Brody Instrumental Activities of Daily Living Scale and the Katz Index of Activities of Daily Living, respectively. The contents and formats of the questionnaires varied considerably. Activities and participation were the most commonly assessed dimensions. In addition, the Activities of Daily Living, mobility and the Instrumental Activities of Daily Living Scale were the most common domains assessed among the included questionnaires. Among the 24 included questionnaires, the most frequently used questionnaires were the Barthel Index, Lawton and Brody Instrumental Activities of Daily Living Scale, and Katz Index of Activities of Daily Living. The content and format of the questionnaires varied considerably, but none of the questionnaires covered all essential dimensions of the International Classification of Functioning, Disability, and Health framework.

    Fecal incontinence can have a profound effect on quality of life. Its prevalence remains uncertain because of stigma, lack of consistent definition, and dearth of validated measures. This study was designed to develop a valid clinical and epidemiologic questionnaire, building on current literature and expertise. Patients and experts undertook face validity testing. Construct validity, criterion validity, and test-retest reliability was undertaken. Construct validity comprised factor analysis and internal consistency of the quality of life scale. The validity of known groups was tested against 77 control subjects by using regression models. Questionnaire results were compared with a stool diary for criterion validity. Test-retest reliability was calculated from repeated questionnaire completion. The questionnaire achieved good face validity. It was completed by 104 patients. The quality of life scale had four underlying traits (factor analysis) and high internal consistency (overall Cronbach alpha = 0.97). Patients and control subjects answered the questionnaire significantly differently (P < 0.01) in known-groups validity testing. Criterion validity assessment found mean differences close to zero. Median reliability for the whole questionnaire was 0.79 (range, 0.35-1). This questionnaire compares favorably with other available instruments, although the interpretation of stool consistency requires further research. Its sensitivity to treatment still needs to be investigated.

    Severe skin diseases, such as epidermolysis bullosa (EB), may have a strong impact not only on patients but also on caregivers. A specific questionnaire evaluating the family impact of dermatological conditions has been created, the Family Dermatology Life Quality Index (FDLQI), but it has not yet been translated in Italian and validated. To evaluate the burden of recessive dystrophic EB on family caregivers, using for the first time the Italian version of the FDLQI, and to validate the instrument. Patients with recessive dystrophic EB participated in a postal survey enquiring about the burden of EB on family caregivers. They completed the Family Strain Questionnaire and the FDLQI and they marked on a silhouette of the human body the skin lesion distribution. Data on 62 family caregivers were collected. The overall mean FDLQI score was 9.8. The most frequently reported problems were the time spent on looking after the patient, emotional distress, physical well-being, and increased household expenditure. FDLQI scores were higher in family caregivers of patients between 10 and 20 years. The Italian FDLQI showed high internal consistency, construct and convergent validity. Factor analysis revealed the presence of one factor structure underlying the items of the FDLQI, which explained 51.5% of the total variance, very similar to the original questionnaire (55.8%). The Italian version of the FDLQI seems to be a useful tool to evaluate the impact of EB on family caregivers. Further studies are necessary to test this instrument in other dermatological conditions. © 2012 The Authors.

    Health Related Quality of Life (HRQOL) instruments need disease and country specific validation. In Arab countries, there is no specific validated questionnaire for assessment of HRQOL in chronic kidney disease (CKD) patients. The aim of this study was to present an Arabic translation, adaptation, and the subsequent validation of the kidney disease quality of life-short form (KDQOL-SFTM) version 1.3 questionnaire in a representative series of Egyptian CKD patients. KDQOL-SFTM version 1.3 was translated into Arabic by two independent translators, and then subsequently translated back into English. After translation disparities were reconciled, the final Arabic questionnaire was tested by interviewing 100 pre-dialysis CKD (stage 1-4) patients randomly selected from outpatients attending the Nephrology clinic at the Main Alexandria University Hospital. Test re-test reliability was performed, with a subsample of 50 consecutive CKD patients, by two interviews 7 days apart and internal consistency estimated by Cronbach's α. Discriminant, concept, and construct validity were assessed. All items of SF-36 met the criterion for internal consistency and were reproducible. Of the 10 kidney disease targeted scales, only three had Cronbach's α <0.7: quality of social interaction (0.23), work status (0.28), and cognitive function (0.60). All disease specific scales were reproducible. Results from discriminant validity showed that the study questionnaire could discriminate between patients' subgroups. As for concept validity, the correlation between all domains of the questionnaire with overall health ratewas significant for all domains except for the work status, sexual function, emotional wellbeing, and role emotional. Furthermore, the correlation between the disease specific domains and the two composite summaries of SF-36 (physical and mental composite summaries) was significant for all domains except for sexual function with mental composite summary. Construct validity was

    The study of quality of life in patients with skin disorders has become more important in recent decades. In the case of lupus erythematosus, most quality-of-life studies have focused on the systemic form of the disease, with less attention being paid to the cutaneous form. The main objective of this study was to evaluate quality of life in patients with cutaneous lupus erythematosus (CLE) using a dermatology-specific questionnaire: the Dermatology Life Quality Index (DLQI). Our secondary objective was to investigate associations between DLQI scores and other aspects of the disease. Thirty-six patients with CLE completed the DLQI questionnaire. Other factors assessed were disease severity (measured using the Cutaneous Lupus Erythematosus Disease Area and Severity Index), time since diagnosis, body surface area affected, previous and current treatments, and the presence of criteria for systemic lupus erythematosus (SLE). According to the DLQI, CLE had a moderate, very large, or extremely large effect on quality of life in 50% of the patients analyzed (18/36). No significant associations were found between DLQI scores and disease severity, time since diagnosis, body surface area affected, number, type, or duration of pharmacologic treatments, or the presence or absence of SLE criteria. CLE has a significant and lasting effect on patient quality of life. This effect is probably primarily due to multiple factors, including the chronic nature of the disease, the visibility of the lesions, and the fact that they can cause disfigurement.

    Bronchiectasis can adversely affect quality of life. However, the tests examining quality of life in bronchiectasis are not sufficient. We examined the validity of a measure designed for COPD, the Seattle Obstructive Lung Disease Questionnaire (SOLQ), in bronchiectasis. In addition, we aimed to compare the quality of life of subjects with bronchiectasis and bronchial hyper-responsiveness with that of those without to identify the effective factors. We studied 78 subjects with clinically stable bronchiectasis and 41 healthy controls matched for age and sex. Subjects were assessed by the SOLQ. A detailed history, physical examination, the Medical Outcomes Study 36-Item Short Form questionnaire, the Hospital Anxiety and Depression Scale, and spirometric measurements were obtained. Cronbach α coefficients, which reflected internal consistency, were >0.70 for all SOLQ components except for treatment satisfaction. SOLQ component scores correlated with all of the component scores of the Medical Outcomes Study 36-Item Short Form questionnaire and the Hospital Anxiety and Depression Scale, confirming their concurrent validity. All SOLQ scores correlated positively with percent-of-predicted FEV1, whereas the physical function, treatment satisfaction, and emotional function correlated negatively with the exacerbation frequency in Pearson analysis. Emotional and physical functions were positively associated with percent-of-predicted FEV1 in linear regression analysis. Compared with subjects without bronchial hyper-responsiveness, those with bronchial hyper-responsiveness had lower FEV1/FVC and more exacerbations/y. Compared with bronchiectasis subjects without bronchial hyper-responsiveness, those with bronchial hyper-responsiveness had significantly lower SOLQ, physical function, and coping skills scores but not emotional function and treatment satisfaction. The SOLQ is a valid instrument for determining quality of life in subjects with bronchiectasis. Subjects with

    Background The aim of this study is to validate the questionnaire ECOS-16 (Assessment of health related quality of life in osteoporosis) for the evaluation of health related quality of life (HRQoL) in post-menopausal women with osteoporosis. Methods An observational, prospective and multi-centre study was carried out among post-menopausal women with osteoporosis in primary care centres and hospital outpatient clinics. All patients attended 2 visits: at baseline and at 6 months. In addition, the subgroup of outpatients attended another visit a month after the baseline to assess the test-retest reliability. The psychometric properties of the questionnaire were evaluated in terms of feasibility, validity (content validity and construct validity) and internal consistency in baseline, and in terms of test-retest reliability and responsiveness to change in visit at month and visit at 6 months, respectively. In all visits, ECOS-16, EUROQoL-5D (EQ-5D) and four 7-point items about health status (general health status, back pain, limitation in daily activities and emotional status) were administered, whereas only outpatients were given MINI-OQLQ (Mini Osteoporosis Quality of Life Questionnaire), besides all clinical variables; and sociodemographic variables at baseline. Results 316 women were consecutively included, 212 from primary care centres and 104 from hospital outpatient clinics. Feasibility: 94.3% of patients answered all items of the questionnaire. The mean administration time was 12.3 minutes. Validity: factor analysis suggested that the questionnaire was unidimensional. In the multivariate analysis, patients with vertebral fractures, co-morbidity and a lower education level showed to have worse HRQoL. Moderate to high correlations were found between the ECOS-16 score and the other health status questionnaires (0.47–0.82). Reliability: internal consistency (Cronbach's α) was 0.92 and test-retest reliability (ICC) was 0.80. Responsiveness to change: ECOS-16

    The study of diet quality in a population provides information for the development of programs to improve nutritional status through better directed actions. The aim of this study was to assess the reproducibility and relative validity of a Mexican Diet Quality Index (ICDMx) for the assessment of the habitual diet of adults. The ICDMx was designed to assess the characteristics of a healthy diet using a validated semi-quantitative food frequency questionnaire (FFQ-Mx). Reproducibility was determined by comparing 2 ICDMx based on FFQs (one-year interval). Relative validity was assessed by comparing the ICDMx (2nd FFQ) with that estimated based on the intake averages from dietary records (nine days). The questionnaires were answered by 97 adults (mean age in years = 27.5, SD = 12.6). Pearson (r) and intraclass correlations (ICC) were calculated; Bland-Altman plots, Cohen’s κ coefficients and blood lipid determinations complemented the analysis. Additional analysis compared ICDMx scores with nutrients derived from dietary records, using a Pearson correlation. These nutrient intakes were transformed logarithmically to improve normality (log10) and adjusted according to energy, prior to analyses. The ICDMx obtained ICC reproducibility values ranged from 0.33 to 0.87 (23/24 items with significant correlations; mean = 0.63), while relative validity ranged from 0.26 to 0.79 (mean = 0.45). Bland-Altman plots showed a high level of agreement between methods. ICDMx scores were inversely correlated (p < 0.05) with total blood cholesterol (r = −0.33) and triglycerides (r = −0.22). ICDMx (as calculated from FFQs and DRs) obtained positive correlations with fiber, magnesium, potassium, retinol, thiamin, riboflavin, pyridoxine, and folate. The ICDMx obtained acceptable levels of reproducibility and relative validity in this population. It can be useful for population nutritional surveillance and to assess the changes resulting from the implementation of nutritional

    Fibromyalgia affects 8% of the population over the age of 40 years, and 75% of the patients with fibromyalgia have poor sleep quality. To assess the effects of hydrotherapy on the physical function and sleep quality of patients with fibromyalgia. Patients were under clinical care at the UNASP Outpatient Clinic. This study assessed 60 female patients with fibromyalgia aged between 30 and 65 years. Out of the 60 patients assessed, 20 were excluded and 10 left the study because they could not comply with the time schedule. All patients completed the following questionnaires: Fibromyalgia Impact Questionnaire (FIQ); Pittsburgh Sleep Quality Index, and Epworth Sleepiness Scale. Training sessions were performed twice a week for two months, each session lasting 60 minutes. Patients' mean age was 45 years, 66% were active workers, and 34% had quit work. Right after the hydrotherapy program, the patients improved the following aspects assessed by use of the FIQ: physical function, work absenteeism, ability to do job, pain intensity, fatigue, morning tiredness, stiffness (P < 0.0001), anxiety (P = 0,0013), and depression (P < 0.0001). Sleep quality (P < 0.0001) and daytime sleepiness (P = 0.0003) also improved. Hydrotherapy improves sleep quality, physical function, professional status, psychological disorders and physical symptoms in patients with fibromyalgia.

    Researchers wishing to assess the health-related quality of life (HRQoL) of women with gynecologic cancers have a range of questionnaires to choose from. In general, disease-, treatment-, or symptom-specific questionnaires are assumed to be better able to identify between-group differences (sensitivity) and changes over time (responsiveness) than are cancer-specific or generic questionnaires. However, little work has tested this assumption in oncology. We set out to (a) identify all multidimensional HRQoL questionnaires used in studies with women with gynecologic cancer and (b) evaluate their track records in identifying minimal clinically important differences (MCIDs), with a view to making recommendations. We searched MEDLINE using the term quality of life and each gynecologic cancer type, as well as the names of identified questionnaires. We used 10% of the scale range as the threshold for an MCID. We identified 1 generic (SF-36/SF-12), 3 cancer-specific (European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire [EORTC QLQ] C30, Functional Assessment of Cancer Therapy-General [FACT-G], and short-form Cancer Rehabilitation Evaluation System [CARES-SF]), and 1 disease-specific (QOL-Ovarian Cancer Patient Version) HRQoL questionnaires and 5 disease-specific (QLQ-OV28, FACT-O for ovarian, QLQ-CX24, FACT-Cx for cervical and FACT-V for vulvar), 1 treatment-specific (FACT and Gynecologic Oncology Group-Ntx for neurotoxicity), and 2 symptom-specific (FACT-Anemia and Functional Assessment of Chronic Illness and Therapy [FACIT]-Fatigue) modules. Twenty-seven articles reported results from 26 studies in which an MCID had been identified. The FACIT's anemia and fatigue subscales were more sensitive, and the neurotoxicity subscale more sensitive and responsive than the FACT-G on at least 1 comparison. However, we found no evidence for superior performance by the FACT-G compared with the SF-36 or EORTC and FACIT disease-specific modules

    To explore the relationship between disability and functional measures with vision-specific quality of life (QoL) measures for people with hemianopia and stroke. The Behavioral Inattention Test (BIT) and the Mayo-Portland Adaptability Inventory (MPAI) were compared with scores on 2 vision-specific QoL measures, the National Eye Institute Visual Function Questionnaire (NEI VFQ-25) and Veteran Low Vision Visual Function Questionnaire (VA LV VFQ-48). Rehabilitation hospitals in Adelaide, South Australia. Stroke patients (n = 24) with homonymous hemianopia. Most of the BIT and MPAI scores were significantly associated with the NEI VFQ-25 and VA LV VFQ-48 scores. Behavioral test scores of the BIT and the MPAI total score correlated with more aspects of the QoL measures than the other components of the BIT and the MPAI. BIT and MPAI measure constructs associated with QoL for people with hemianopia following stroke. Vision-specific QoL questionnaires can complement the functional instruments by identifying the domains of difficulty, based on the instrument's subscale, that can guide rehabilitation therapists to address the person's deficit.

    Patient-reported outcome measures (PROMs) have the potential to be extremely valuable in the clinical care delivery for women who report heavy menstrual bleeding (HMB). Increasingly, studies on HMB have incorporated PROMs to evaluate the impact of bleeding on quality of life. These measures have included semiquantitative charts and pictograms, questionnaires to assess symptoms and impact on quality of life, and health-related quality of life questionnaires. Recent systematic reviews have highlighted inconsistency of outcome measurement across studies on HMB as a challenge limiting the interpretability of the body of literature and the ability to generate consensus on the relative effectiveness of treatment options. Consequently, research initiatives and international collaborations are working to harmonize outcome measurement. Harmonizing the use of questionnaires in research and clinical care has the potential to improve patient-centered care delivery for women with HMB and improve the generation of patient-focused evidence-based guidelines for the evaluation and treatment of HMB.

    Despite an increase in ENT postal questionnaires, the quality of their methodology has been questioned (Ramphul et al. in J Laryngol Otol 119:175-178, 1). This retrospective study examined whether quality and utility of such questionnaires published since 2005 has improved. Seventeen consultant postal questionnaires published between 2005 and 2012 were reviewed. Quality of questionnaires was assessed using a 30-point score based on compliance with 15 criteria previously established to evaluate postal questionnaire study-design (Ramphul et al. in J Laryngol Otol 119:175-178, 1). Citation rates were used as an indicator of utility. The specific comments made in each citing paper was reviewed providing information on whether questionnaire findings (a) had an impact on clinical practice, (b) were the citing comments positive, (c) negative or (d) non-specific. Recurrent methodological flaws were identified in all questionnaires. The average score assigned was 44 %, versus 32 % previously reported (Ramphul et al. in J Laryngol Otol 119:175-178, 1) (P < 0.01, Student's t test). The low citation rate demonstrates poor utility for postal questionnaires. Citations were general non-specific referencing with no clear indication that questionnaire findings positively impacted clinical practice. In conclusion, although the quality of ENT postal questionnaire has improved since the original study (Ramphul et al. in J Laryngol Otol 119:175-178, 1), important recurring methodological flaws still exist. The poor utility, based on low citation rates, also reflects the continued deficiencies in design quality. It is recommended that authors of questionnaire-based research should ensure that guidelines for questionnaire design are adhered in order to improve the validity of findings and hence impact on clinical practice.

    Food allergy is an emerging health problem. Several questionnaires can be used to establish health-related quality of life (HRQOL) in food allergy patients. Current questionnaires should be translated in such a way that they take account of the culture of the country in which they are to be used. Objective: To translate and perform a cross-sectional validation of the Food Allergy Quality of Life Questionnaire-Parent Form (FAQLQ-PF). The parents of 54 children diagnosed with food allergy were recruited to assess the Spanish version of the FAQLQ-PF (S-FQLQ-PF). The S-FQLQ-PF was translated into Spanish according to WHO guidelines (including a forward-backward translation). The statistical analysis showed that feasibility, reliability, and internal consistency were very good for the global S-FAQLQ-PF score and for the different domains. Assessment of construct validity indicated that S-FAQLQ-PF has reduced capacity for measurement of HRQOL in younger children. Cross-sectional validation of the S-FAQLQ-PF demonstrated that HRQOL of a Spanish pediatric population was affected by patient age, severity of symptoms, and number of reactions. HRQOL was not affected by sex, food implicated, number of foods implicated, ingestion of the implicated food, or presence of anaphylaxis. Translation into Spanish and cultural validation of the FAQLQ-PF demonstrated the influence of factors, such as patient age, severity of symptoms, and number of reactions on the HRQOL of a pediatric Spanish population.

    The "Provence Alpes Côte d'Azur" (PACA) region, in the South East of France, is one of Europe's regions most influenced by the atmospheric pollution. During the last 15 years, the industrial emissions decrease caused an evolution of the atmospheric pollution nature. Nowadays, atmospheric pollution is more and more influenced by the road traffic, the dominating pollution source in urban zones for the PACA region. Combined with this intense road traffic, the strong hot season of the Mediterranean climate contributes to the region bad air quality; it is known to be one of the worse in Europe. The recognized air pollution effects over public health include increased risk of hospital admissions and mortality by respiratory or cardiovascular diseases. The combination of these serious pollution related health hazards with senior and children vulnerabilities leads to serious sanitary concerns. Over the 1990-2005 period, we obtained, using the non-parametric Mann-Kendall test from annual mortality dataset (CépiDC), decreasing trends for Asthma (-5.00% year -1), Cardiovascular (-0.73% year -1), Ischemic (-0.69% year -1) and cerebrovascular diseases (-3.10% year -1). However, for "Other heart diseases" (+0.10% year -1) and "Respiratory" (+0.10% year -1) an increase was observed. The development of an adequate tool to understand impacts of pollution levels is of utmost importance. Different pollutants have different health endpoints, information may be lost through the use of a single index consequently, in this study we present the modified formula of air quality index, based on Cairncross's concept the Aggregate Risk Index (ARI). ARI is based on the relative risk of the well-established increased daily mortality, or morbidity, enabling an assessment of additive effects of short-term exposure to the main air pollutants: PM 2.5, PM 10, SO 2, O 3 and NO 2 in order to account for the reality of the multiple exposures impacts of chemical agents. The ARI, developed per pathology

    The purpose of the paper is to assess the groundwater quality near the landfill sites using landfill water pollution index (LWPI). In order to investigate the scale of groundwater contamination, three landfills (E, H and S) in different stages of their operation were taken into analysis. Samples of groundwater in the vicinity of studied landfills were collected four times each year in the period from 2004 to 2014. A total of over 300 groundwater samples were analysed for pH, EC, PAH, TOC, Cr, Hg, Zn, Pb, Cd, Cu, as required by the UE legal acts for landfill monitoring system. The calculated values of the LWPI allowed the quantification of the overall water quality near the landfill sites. The obtained results indicated that the most negative impact on groundwater quality is observed near the old Landfill H. Improper location of piezometer at the Landfill S favoured infiltration of run-off from road pavement into the soil-water environment. Deep deposition of the groundwater level at Landfill S area reduced the landfill impact on the water quality. Conducted analyses revealed that the LWPI can be used for evaluation of water pollution near a landfill, for assessment of the variability of water pollution with time and for comparison of water quality from different piezometers, landfills or time periods. The applied WQI (Water Quality Index) can also be an important information tool for landfill policy makers and the public about the groundwater pollution threat from landfill.

    Despite the existence of the universal right to a healthy environment, the right is being violated in some populations. The objective of the current study is to verify environmental discrimination associated with socioeconomic status in Korea, using synthetic air quality index and multiple indicators of socioeconomic status. The concentrations of NO₂(nitrogen dioxide), CO (carbon monoxide), SO₂(sulfur dioxide), PM10 (particulate matter with an aerodynamic diameter <10 μm), and O₃(ozone) in ambient air were integrated into a synthetic air quality index. Socioeconomic status was measured at individual level (income, education, number of household members, occupation, and National Basic Livelihood status) and area level (neighborhood index). The neighborhood index was calculated in the finest administrative unit (municipality) by performing standardization and integration of municipality-level data of the following: number of families receiving National Basic Livelihood, proportion of people engaged in an elementary occupation, population density, and number of service industries. Each study participant was assigned a neighborhood index value of the municipality in which they reside. Six regression models were generated to analyze the relationship between socioeconomic status and overall air pollution. All models were adjusted with sex, age, and smoking status. Stratification was conducted by residency (urban/rural). Moran's I was calculated to identify spatial clusters, and adjusted regression analysis was conducted to account for spatial autocorrelation. Results showed that people with higher neighborhood index, people living with smaller number of family members, and people with no education lived in municipalities with better overall air quality. The association differed by residency in some cases, and consideration of spatial autocorrelation altered the association. This study gives strength to the idea that environmental discrimination exists in some

    Autoimmune bullous dermatoses (AIBD) are rare, severe diseases resulting from some antibodies activity against the different adhesion structures within the skin and/or mucosa. Few studies investigated quality of life (QOL) in AIBD by generic and dermatology-specific instruments, all reporting strong impact on QOL. Recently, disease-specific measurement tools have been developed: Autoimmune Bullous Disease Quality of Life (ABQOL) and Treatment of Autoimmune Bullous Disease Quality of Life (TABQOL) questionnaires. The aim of this study was to test the reliability and validity of ABQOL and TABQOL by developing the first foreign language versions and to evaluate ABQOL and TABQOL in Polish patients. The study enrolled 80 patients from the tertiary referral center for AIBD at the outpatient clinic or on admission to the hospital. Sixty six patients completed the 17-item questionnaires of each ABQOL and TABQOL at day 0 and after 5-7 days. Both questionnaires were translated into Polish according to protocol. The internal consistency and test-retest reliability were high (Cronbach α=0.95 for ABQOL, α=0.87 for TABQOL), (R=0.98 for ABQOL, R=0.86 for TABQOL). In convergent validity, the correlation of ABQOL and TABQOL was strong (R=0.81), but low with objective disease activity scales. The strongest impact of AIBD on QOL has been observed in flares and in patients with the onset below 70 years of age. The patients with bullous pemphigoid had the highest QOL compared to other AIBD patients. The ABQOL and TABQOL are reliable and valid instruments for the assessment of QOL in AIBD.

    Medical students face new challenges at the beginning of college life, such as being responsible for oneself, an unfamiliar environment, social obligations, and academic stress, all of which influence or even heavily change their sleep quality and life, leading to sleep-related problems to some degree. This study investigated the relationship between sleep quality and behavior among students at the Inner Mongolia Medical University in China. Self-administered questionnaires were used to collect information on sociodemographic characteristics and lifestyle habits. The Pittsburgh Sleep Quality Index was also used. A total of 6044 and 6085 students completed the questionnaires in 2011 and 2013. According to the index, 27.8% (1694) of students had poor sleep quality with major risk factors being poor academic performance and interpersonal relationships in 2013. Among others, regular exercise less than three times a week, skipping breakfast, and studying in higher grades were associated with poor sleep quality. These results will help university administrators understand the risk factors of poor sleep quality among students, which can be improved through individual efforts, and provide adequate counseling and systematic education to improve their behavior and lifestyle.

    The Dietary Guideline Index, a measure of diet quality, was updated to reflect the 2013 Australian Dietary Guidelines. This paper describes the revision of the index (DGI-2013) and examines its use in older adults. The DGI-2013 consists of 13 components reflecting food-based daily intake recommendations of the Australian Dietary Guidelines. In this cross-sectional study, the DGI-2013 score was calculated using dietary data collected via an 111-item food frequency questionnaire and additional food-related behaviour questions. The DGI-2013 score was examined in Australian adults (aged 55–65 years; n = 1667 men; 1801 women) according to sociodemographics, health-related behaviours and BMI. Women scored higher than men on the total DGI-2013 and all components except for dairy. Those who were from a rural area (men only), working full-time (men only), with lower education, smoked, did not meet physical activity guidelines, and who had a higher BMI, scored lower on the DGI-2013, highlighting a group of older adults at risk of poor health. The DGI-2013 is a tool for assessing compliance with the Australian Dietary Guidelines. We demonstrated associations between diet quality and a range of participant characteristics, consistent with previous literature. This suggests that the DGI-2013 continues to demonstrate convergent validity, consistent with the original Dietary Guideline Index. PMID:26978399
