Responsiveness of the individual work performance questionnaire  

PubMed Central

Background Individual work performance is an important outcome measure in studies in the workplace. Nevertheless, its conceptualization and measurement has proven challenging. To overcome limitations of existing scales, the Individual Work Performance Questionnaire (IWPQ) was recently developed. The aim of the current study was to gain insight into the responsiveness of the IWPQ. Methods Data were used from the Be Active & Relax randomized controlled trial. The aim of the trial was to investigate the effectiveness of an intervention to stimulate physical activity and relaxation of office workers, on need for recovery. Individual work performance was a secondary outcome measure of the trial. In total, 39 hypotheses were formulated concerning correlations between changes on the IWPQ scales and changes on similar constructs (e.g., presenteeism) and distinct constructs (e.g., need for recovery) used in the trial. Results 260 Participants completed the IWPQ at both baseline and 12 months of follow-up. For the IWPQ scales, 23%, 15%, and 38%, respectively, of the hypotheses could be confirmed. In general, the correlations between change scores were weaker than expected. Nevertheless, at least 85% of the correlations were in the expected direction. Conclusions Based on results of the current study, no firm conclusions can be drawn about the responsiveness of the IWPQ. Several reasons may account for the weaker than expected correlations. Future research on the IWPQ’s responsiveness should be conducted, preferably in other populations and intervention studies, where greater changes over time can be expected. PMID:24885593

Increasing response rates to postal questionnaires: systematic review  

PubMed Central

Objective To identify methods to increase response to postal questionnaires. Design Systematic review of randomised controlled trials of any method to influence response to postal questionnaires. Studies reviewed 292 randomised controlled trials including 258?315 participants Intervention reviewed 75 strategies for influencing response to postal questionnaires. Main outcome measure The proportion of completed or partially completed questionnaires returned. Results The odds of response were more than doubled when a monetary incentive was used (odds ratio 2.02; 95% confidence interval 1.79 to 2.27) and almost doubled when incentives were not conditional on response (1.71; 1.29 to 2.26). Response was more likely when short questionnaires were used (1.86; 1.55 to 2.24). Personalised questionnaires and letters increased response (1.16; 1.06 to 1.28), as did the use of coloured ink (1.39; 1.16 to 1.67). The odds of response were more than doubled when the questionnaires were sent by recorded delivery (2.21; 1.51 to 3.25) and increased when stamped return envelopes were used (1.26; 1.13 to 1.41) and questionnaires were sent by first class post (1.12; 1.02 to 1.23). Contacting participants before sending questionnaires increased response (1.54; 1.24 to 1.92), as did follow up contact (1.44; 1.22 to 1.70) and providing non-respondents with a second copy of the questionnaire (1.41; 1.02 to 1.94). Questionnaires designed to be of more interest to participants were more likely to be returned (2.44; 1.99 to 3.01), but questionnaires containing questions of a sensitive nature were less likely to be returned (0.92; 0.87 to 0.98). Questionnaires originating from universities were more likely to be returned than were questionnaires from other sources, such as commercial organisations (1.31; 1.11 to 1.54). Conclusions Health researchers using postal questionnaires can improve the quality of their research by using the strategies shown to be effective in this systematic review. What is already known on this topicPostal questionnaires are widely used in the collection of data in epidemiological studies and health researchNon-response to postal questionnaires reduces the effective sample size and can introduce biasWhat this study addsThis systematic review includes more randomised controlled trials than any previously published review or meta-analysis no questionnaire responseThe review has identified effective ways to increase response to postal questionnairesThe review will be updated regularly in the Cochrane Library PMID:12016181

Maximising response to postal questionnaires – A systematic review of randomised trials in health research  

PubMed Central

Background Postal self-completion questionnaires offer one of the least expensive modes of collecting patient based outcomes in health care research. The purpose of this review is to assess the efficacy of methods of increasing response to postal questionnaires in health care studies on patient populations. Methods The following databases were searched: Medline, Embase, CENTRAL, CDSR, PsycINFO, NRR and ZETOC. Reference lists of relevant reviews and relevant journals were hand searched. Inclusion criteria were randomised trials of strategies to improve questionnaire response in health care research on patient populations. Response rate was defined as the percentage of questionnaires returned after all follow-up efforts. Study quality was assessed by two independent reviewers. The Mantel-Haenszel method was used to calculate the pooled odds ratios. Results Thirteen studies reporting fifteen trials were included. Implementation of reminder letters and telephone contact had the most significant effect on response rates (odds ratio 3.7, 95% confidence interval 2.30 to 5.97 p = <0.00001). Shorter questionnaires also improved response rates to a lesser degree (odds ratio 1.4, 95% confidence interval 1.19 to 1.54). No evidence was found that incentives, re-ordering of questions or including an information brochure with the questionnaire confer any additional advantage. Conclusion Implementing repeat mailing strategies and/or telephone reminders may improve response to postal questionnaires in health care research. Making the questionnaire shorter may also improve response rates. There is a lack of evidence to suggest that incentives are useful. In the context of health care research all strategies to improve response to postal questionnaires require further evaluation. PMID:16504090

Reliability and validity of a Mental Health System Responsiveness Questionnaire in Iran  

PubMed Central

Background The Health System Responsiveness Questionnaire is an instrument designed by the World Health Organization (WHO) in 2000 to assess the experience of patients when interacting with the health care system. This investigation aimed to adapt a Mental Health System Responsiveness Questionnaire (MHSRQ) based on the WHO concept and evaluate its validity and reliability to the mental health care system in Iran. Design In accordance with the WHO health system responsiveness questionnaire and the findings of a qualitative study, a Farsi version of the MHSRQ was tailored to suit the mental health system in Iran. This version was tested in a cross-sectional study at nine public mental health clinics in Tehran. A sample of 500 mental health services patients was recruited and subsequently completed the questionnaire. Item missing rate was used to check the feasibility while the reliability of the scale was determined by assessing the Cronbach's alpha and item total correlations. The factor structure of the questionnaire was investigated by performing confirmatory factor analysis (CFA). Results The results showed a satisfactory feasibility since the item missing value was lower than 5.2%. With the exception of access domain, reliability of different domains of the questionnaire was within a desirable range. The factor loading showed an acceptable unidimentionality of the scale despite the fact that three items related to access did not perform well. The CFA also indicated good fit indices for the model (CFI=0.99, GFI=0.97, IFI=0.99, AGFI=0.97). Conclusions In general, the findings suggest that the Farsi version of the MHSRQ is a feasible, reliable, and valid measure of the mental health system responsiveness in Iran. Changes to the questions related to the access domain should be considered in order to improve the psychometric properties of the measure. PMID:25079288

Meta-analysis of randomised trials of monetary incentives and response to mailed questionnaires  

PubMed Central

Study objective: To quantify the increase in mailed questionnaire response attributable to a monetary incentive. Design: A systematic search for randomised controlled trials of monetary incentives and mailed questionnaire response was conducted. For each trial identified, logistic regression was used to estimate the odds ratio for response per $0.01 incentive increase. Odds ratios were pooled in a series of random effect meta-analyses stratified by the minimum and maximum amounts offered. Piecewise logistic regression was used to estimate the odds ratio for response per $0.01 increase given in each of five incentive ranges. Setting: Populations in several developed countries, predominantly the USA. Participants: 85 671 randomised participants from 88 trials. Main results: The pooled odds ratios for response per $0.01 incentive decreased monotonically as the maximum amount of incentive offered increased. The piecewise logistic regression model estimated that for incentive amounts up to $0.50, each additional $0.01 increased the odds of response by about 1% (pooled OR = 1.012, 95%CI 1.007 to 1.016). The effects on response above $0.50 were smaller and decreased monotonically in the ranges: $0.50–0.99, $1–1.99, $2–4.99, $5.00 and over, but remained statistically significant up to $5. Conclusions: This meta-analysis of the best available evidence shows that monetary incentives increase mailed questionnaire response. Researchers should include small amounts of money with mailed questionnaires rather than give no incentive at all. PMID:16234429

A procedure for removing the effect of response bias errors from waterfowl hunter questionnaire responses  

USGS Publications Warehouse

Response bias errors are studied by comparing questionnaire responses from waterfowl hunters using four large public hunting areas with actual hunting data from these areas during two hunting seasons. To the extent that the data permit, the sources of the error in the responses were studied and the contribution of each type to the total error was measured. Response bias errors, including both prestige and memory bias, were found to be very large as compared to non-response and sampling errors. Good fits were obtained with the seasonal kill distribution of the actual hunting data and the negative binomial distribution and a good fit was obtained with the distribution of total season hunting activity and the semi-logarithmic curve. A comparison of the actual seasonal distributions with the questionnaire response distributions revealed that the prestige and memory bias errors are both positive. The comparisons also revealed the tendency for memory bias errors to occur at digit frequencies divisible by five and for prestige bias errors to occur at frequencies which are multiples of the legal daily bag limit. A graphical adjustment of the response distributions was carried out by developing a smooth curve from those frequency classes not included in the predictable biased frequency classes referred to above. Group averages were used in constructing the curve, as suggested by Ezekiel [1950]. The efficiency of the technique described for reducing response bias errors in hunter questionnaire responses on seasonal waterfowl kill is high in large samples. The graphical method is not as efficient in removing response bias errors in hunter questionnaire responses on seasonal hunting activity where an average of 60 percent was removed.

The Korean version of the Carpal Tunnel Questionnaire. Cross cultural adaptation, reliability, validity and responsiveness.  

PubMed

The purpose of this study was to translate and culturally adapt the Carpal Tunnel Questionnaire to produce an equivalent Korean version. A total of 53 patients completed the Korean version of the Carpal Tunnel Questionnaire pre-operatively and 3 months after open carpal tunnel release. All 53 also completed the Korean version of the Disabilities of Arm, Shoulder, and Hand questionnaire pre-operatively and 3 months post-operatively. Reliability was measured by determining the test-retest reliability and internal consistency. Test-retest reliability was assessed using intraclass correlation coefficients and paired t-tests, and internal consistency using Cronbach's alpha coefficients. Pearson correlation analysis was carried out on the Korean version of the Carpal Tunnel Questionnaire scores and the Korean version of the Disabilities of Arm, Shoulder, and Hand scores to assess construct validity. Responsiveness was evaluated using effect sizes and standardized response means. The reliability of the Korean version of the Carpal Tunnel Questionnaire was good. The scores in the Korean version of the Disabilities of Arm, Shoulder, and Hand strongly correlated with the scores in the Korean version of the Carpal Tunnel Questionnaire. Standardized response mean and effect size were both large for the Korean version of the Carpal Tunnel Questionnaire. The study shows that the Korean version of the Carpal Tunnel Questionnaire is a reliable, valid and responsive instrument for measuring outcomes in carpal tunnel syndrome. PMID:25005562

A prospective study of response error in food history questionnaires: implications for foodborne outbreak investigation.  

PubMed Central

To explore the problem of response error in food history data, a prospective study examined the validity of food questionnaire data obtained five days after the study meal. Unobtrusive observation of 64 persons selecting two different foods at a buffet-style luncheon were compared with subsequent histories of food consumption. The predictive value of a positive response was 0.73 for one food and 0.82 for the second food. The response error measures obtained were then applied to data from a published foodborne outbreak to illustrate the impact of predictive value positive and predictive value negative levels on the significance of a food-illness association. Public health workers engaged in food questionnaire administration and analysis must consider response error and should explore methods of reducing this problem through attention to both interviewer-respondent interaction and questionnaire design.

Responsiveness of the Multiple Sclerosis International Quality of Life questionnaire to disability change: a longitudinal study  

PubMed Central

Background Responsiveness, defined as the ability to detect a meaningful change, is a core psychometric property of an instrument measuring quality of life (QoL) rarely reported in multiple sclerosis (MS) studies. Objective To assess the responsiveness of the Multiple Sclerosis International Quality of Life (MusiQoL) questionnaire to change in disability over 24 months, defined by change in the Expanded Disability Status Scale (EDSS) score. Methods Patients with MS were enrolled into a multicenter, longitudinal observational study. QoL was assessed using both the MusiQoL and the 36-Item Short-Form (SF-36) instruments at baseline and every 6 months thereafter up to month 24; neurological assessments, including EDSS score, were performed at each evaluation. Results The 24-month EDSS was available for 524 patients. In the 107 worsened patients, two specific dimensions of MusiQoL, the sentimental and sexual life and the relationships with health care system dimensions, and ‘physical’ scores of SF-36 showed responsiveness. Conclusions Whereas specific dimensions of MusiQoL identified EDSS changes, the MusiQoL index did not detect disability changes in worsened MS patients in a 24-month observational study. Future responsiveness validation studies should include longer follow-up and more representative samples. PMID:23895207

A qualitative evaluation of questions and responses from five occupational questionnaires developed to assess exposures.  

PubMed

Questionnaires are increasingly being used in the workplace to assess exposures to chemicals and other agents. Although the literature contains much information on questionnaire design in general, little information is available on the challenges related to questionnaires applied to the occupational setting. Questionnaires on dry cleaning workers, nurses, farmers, car mechanics, and truck drivers were administered to a total of 25 people currently performing one of these jobs. After asking each question, the interviewer probed to identify the difficulties the respondents had in answering the questions. Overall, the respondents were able to answer the questions. Problems were found, however, with particular questions that reduced the effectiveness of the questionnaire. These included the use of unclear terms, questions open to multiple interpretations, difficult computational requirements (e.g., asking for averages for highly variable tasks), ineffective transitions between topics, and overlapping response categories. This type of testing is a crucial part of questionnaire development and can be used to effectively identify potential problems with questions and, therefore, improve them to enhance collection of higher-quality data for assessments of occupational exposures.

Development and validation of a questionnaire to evaluate medical students' and residents' responsibility in clinical settings.  

PubMed

There is a shortage of quantitative measures for assessing the concept of responsibility as a fundamental construct in medical education, ethics and professionalism in existing literature. This study aimed to develop an instrument for measuring responsibility in both undergraduate and graduate medical students during clinical training. Instrument content was based on literature review and mainly qualitative data obtained from a published grounded theory research. The draft questionnaire (Persian version) was then validated and revised with regard to face and content validity. The finalized 41-item questionnaire consists of four domains that were identified using factor analysis. Test-retest reliability and internal consistency were also assessed. Test-retest reliability was rather high, ranging between 0.70 and 0.75 for all domains. Cronbach's alpha coefficients were 0.75 - 0.76 for all domains and 0.90 for the composite scale of the whole questionnaire. Correlations between the four domains of the instrument were also satisfactory (r ? 0.47 for most domains). The correlation between each domain and the composite scale was higher than its correlation with other domains (r ? 0.79 for most domains). The instrument demonstrated good construct and internal validity, and can be suitable for measuring the concept of responsibility in practice in different groups of undergraduate and graduate medical trainees (MTs).

Background: Assessment of quality-of-life (QOF) as an outcome measure after deep brain stimulation (DBS) surgery in patients with Parkinson’s disease (PD) need a valid, reliable and responsive instrument. The aim of the current study was to determine responsiveness of validated Persian version of PD questionnaire with 39-items (PDQ-39) after DBS surgery in patients with PD. Methods: Eleven patients with PD, who were candidate for DBS operation between May 2012 and June 2013 were assessed. PDQ-39 and short-form questionnaire with 36-items (SF-36) were used. To assess responsiveness of PDQ-39 standardized response mean (SRM) was used. Results: Mean age was 51.8 (8.8) and all of the patients, but just one were male (10 patients). Mean duration of the disease was 8.7 (2.1) years. Eight patients were categorized as moderate using Hoehn and Yahr (H and Y) classification. All patients had a better H and Y score compared with the baseline evaluation (3.09 vs. 0.79). The amount of SRM was above 0.70 for all domains means a large responsiveness for PDQ-39. Conclusion: Persian version of PDQ-39 has an acceptable responsiveness and could be used to assess as an outcome measure to evaluate the effect of therapies on PD.

The reliability, validity, and preliminary responsiveness of the Eye Allergy Patient Impact Questionnaire (EAPIQ)  

PubMed Central

Background The Eye Allergy Patient Impact Questionnaire (EAPIQ) was developed based on a pilot study conducted in the US and focus groups with eye allergy sufferers in Europe. The purpose of this study was to present the results of the psychometric validation of the EAPIQ. Methods One hundred forty six patients from two allergy clinics completed the EAPIQ twice over a two-week period during the fall and winter allergy seasons, along with concurrent measures of health status, work productivity, and utility. Construct validity, reliability (internal consistency and test-retest), concurrent, known-group, and clinical validities, and responsiveness of the EAPIQ were assessed. Known-group validity was assessed by comparing EAPIQ scale scores between patients grouped according to their self-rating of ocular allergy severity (no symptoms, very mild, mild, moderate, severe, very severe). Clinical validity was assessed by assessing differences in EAPIQ scores between groups of patients rated by their clinician as non-symptomatic, mild, moderate, and severe. Results and Discussion Results from the validation study suggested the deletion of 14 of 43 items (including embedded questions) that required patients to complete the percentage of time they were troubled by something (daily activity limitations/emotional troubles). These items yielded a significant amount of missing or inconsistent data (50%). The resulting factor analysis suggested four domains: symptoms, daily life impact, psychosocial impact, and treatment satisfaction. When included as separate scales, the symptom-bother and symptom-frequency scales were highly correlated (> 0.9). As a consequence, and due to superior discriminative validity, the symptom bother and frequency items were summed. All items met the tests for item convergent validity (item-scale correlation = 0.4). The success rate for item discriminant validity testing was 97% (item-scale correlation greater with own scale than with any other). The criterion for internal consistency reliability (alpha coefficient ? 0.70) was met for all EAPIQ scales (range 0.89–0.93), as was the criterion for test-retest reliability (intraclass correlation [ICC] ? 0.70). Largely moderate correlations between the scales of the EAPIQ and the mini Rhinoconjunctivitis Quality of Life Questionnaire (miniRQLQ) and low correlations with the Health Utilities Index 2/3 (HUI2/3) were indicative of satisfactory concurrent validity. The EAPIQ symptoms, Daily Life Impact, and Psychosocial Impact scales were able to distinguish between patients differing in eye allergy symptom severity, as rated by patients and clinicians, providing evidence of satisfactory known-group and clinical validities, respectively. Preliminary analyses indicated the EAPIQ Symptoms, Daily Life Impact, and Psychosocial Impact scales to be responsive to changes in eye allergies. Conclusion Following item reduction, construct validity, reliability, concurrent validity, known-group validity, and preliminary responsiveness were satisfactory for the EAPIQ in this population of ocular allergy patients.

Appropriate questionnaires for knee arthroplasty. Results of a survey of 3600 patients from The Swedish Knee Arthroplasty Registry.  

PubMed

The Swedish Knee Arthroplasty Registry (SKAR) has recorded knee arthroplasties prospectively in Sweden since 1975. The only outcome measure available to date has been revision status. While questionnaires on health outcome may function as more comprehensive endpoints, it is unclear which are the most appropriate. We tested various outcome questionnaires in order to determine which is the best for patients who have had knee arthroplasty as applied in a cross-sectional, discriminative, postal survey. Four general health questionnaires (NHP, SF-12, SF-36 and SIP) and three disease/site-specific questionnaires (Lequesne, Oxford-12, and WOMAC) were tested on 3600 patients randomly selected from the SKAR. Differences were found between questionnaires in response rate, time required for completion, the need for assistance, the efficiency of completion, the validity of the content and the reliability. The mean overall ranks for each questionnaire were generated. The SF-12 ranked the best for the general health, and the Oxford-12 for the disease/site-specific questionnaires. These two questionnaires could therefore be recommended as the most appropriate for use with a large knee arthroplasty database in a cross-sectional population. PMID:11341416

Patients’ responses to transient ischaemic attack symptoms: a cross-sectional questionnaire study in Australian general practices  

PubMed Central

Background Consensus guidelines for transient ischaemic attack (TIA) recommend urgent investigation and management, but delays in management occur and are attributable to patient and health system factors. Aim To establish general practice patients’ anticipated responses to TIA symptoms, and associations of appropriate responses. Design and setting A cross-sectional questionnaire-based study in Australian general practices. Method Consecutive patients attending general practices completed questionnaires that contained the Stroke Action Test (STAT) adapted for TIA about demographic, health system use, and stroke risk factors. STAT elicits appropriate or inappropriate anticipated responses to 28 symptom complexes. Anticipated actions in-hours and out-of-hours were elicited. Associations of independent variables with adapted-STAT scores were tested with multiple linear regression. Results There were 854 participants (response rate 76.9%). Urgent healthcare-seeking responses to transient neurological symptoms ranged from 96.8% for right-sided weakness with dysphasia to 59.1% for sudden dizziness. Associations of higher adapted-STAT scores were older age, Indigenous status, previous after-hours services use, self-perception of health as poor, and familiarity with a stroke public awareness campaign. A personal or family history of stroke, smoking status, and time of event (in-hours/out-of-hours) were not significantly associated with adapted-STAT scores. Conclusion Most general practice attendees expressed intentions to seek health care urgently for most symptoms suggestive of TIA, with highest levels of urgency observed in high stroke-risk scenarios. Intentions were not associated with a number of major risk factors for TIA and might be improved by further educational interventions, either targeted or at population level. PMID:25548313

Occupational health risks of pathologists - results from a nationwide online questionnaire in Switzerland  

PubMed Central

Background Pathologists are highly trained medical professionals who play an essential part in the diagnosis and therapy planning of malignancies and inflammatory diseases. Their work is associated with potential health hazards including injuries involving infectious human tissue, chemicals which are assumed to be carcinogenic or long periods of microscope and computer work. This study aimed to provide the first comprehensive assessment of the health situation of pathologists in Switzerland. Methods Pathologists in Switzerland were contacted via the Swiss Society of Pathologists and asked to answer an ethically approved, online anonymous questionnaire comprising 48 questions on occupational health problems, workplace characteristics and health behaviour. Results 163 pathologists participated in the study. Forty percent of pathologists reported musculoskeletal problems in the previous month. The overall prevalence was 76%. Almost 90% of pathologists had visual refraction errors, mainly myopia. 83% of pathologists had experienced occupational injuries, mostly cutting injuries, in their professional career; more than one fifth of participants reported cutting injuries in the last year. However, long lasting injuries and infectious diseases were rare. Depression and burnout affected every eighth pathologist. The prevalence of smoking was substantially below that of the general Swiss population. Conclusions The results of this study suggest that more care should be taken in technical and personal protective measures, ergonomic workplace optimisation and reduction of work overload and work inefficiencies. Despite the described health risks, Swiss pathologists were optimistic about their future and their working situation. The high rate of ametropia and psychological problems warrants further study.

Craving and Subjective Responses to Alcohol Administration: Validation of the Desires for Alcohol Questionnaire in the Human Laboratory  

PubMed Central

Objective: The abbreviated Desires for Alcohol Questionnaire (DAQ) is a self-report assessment of craving comprising the following subscales: (a) strong desires/intentions to drink, (b) negative reinforcement, and (c) positive reinforcement and ability to control drinking. Although the DAQ is sensitive to changes in alcohol craving precipitated by alcohol administration and/or cue exposure, no studies to date have examined the relationship between DAQ scores and subjective responses to alcohol. This study addresses this gap in the literature by testing the relationship between subjective responses to alcohol during alcohol administration and DAQ scores assessed 1 month later. Method: Individuals with alcohol dependence (n = 32) completed a randomized, single-blinded, intravenous alcohol administration in the laboratory in which subjective responses to the alcohol were measured, followed by a visit to the laboratory 1 month later to complete the DAQ. Results: Analyses revealed robust associations between DAQ scores and alcohol craving during alcohol administration (partial correlations: r = .43–.50, ps < .01), with the exception of the positive reinforcement subscale (r = .20, p = .30). Subjective intoxication and sedation were only associated with the negative reinforcement subscale of the DAQ (r = .38, p < .05 and r = .33, p < .05, respectively). Conclusions: Craving, captured by the DAQ, is reliably and positively associated with alcohol-induced craving. The DAQ is also associated with specific dimensions of subjective responses to alcohol. These results support the clinical utility of the DAQ, particularly in large samples where experimental manipulations may not be feasible. PMID:23948540

Knowledge and Behaviour of Young People Concerning Fertility Risks – Results of a Questionnaire  

PubMed Central

Purpose: The aim of this study was, in the light of the increasing number of involuntarily childless couples, to investigate the state of knowledge of young people of fertile age about the risks for fertility disorders and their own risk behaviour. In addition, we wanted to check for a relationship between these aspects and the motives for wanting children, individual personality traits and psychological status. Materials and Methods: 498 women and men between the ages of 18 and 30 years participated in an anonymous survey. The sample consisted of 153 medical students, 190 students from other faculties and 155 vocational trainees. Their knowledge was tested by way of open questions on reproduction. The sum total from relevant life-style factors was used to estimate their risk-taking behaviour. Their psychic states were examined using the Health Questionnaire for Patients “Gesundheitsfragebogen für Patienten” PHQ-D, in addition the Leipzig Questionnaire on Motives for Wanting Children “Der Leipziger Fragebogen zu Kinderwunschmotiven” and the short version of the “Big Five Inventory” BFI-K were used. Results: The participants were aware of the risks for fertility disorders but did not always correctly assess their influence on fertility. Their knowledge about reproduction was rather low (on average 6.3 from 16 points). Medical students had a significantly higher state of knowledge and exhibited less risky behaviour as compared to the other two groups. Depressiveness and risky behaviour correlated positively and emotional aspects played the major role in attitudes towards having children. Risk behaviour was best predicted by the variables depressiveness, low level of knowledge and the feeling of being restricted in personal life by children. Discussion: Lack of knowledge on the topics fertility and reproduction could be a reason for risky behaviour and thus have a negative impact on lifestyle factors relating to fertility. Young people are aware of the risk factors that may affect fertility but do not always act accordingly. Primary prevention or, respectively, health promotion is thus necessary to prevent further increases in the number of infertile couples. PMID:24771934

[Responsiveness to the change in the Work Performance Questionnaire (Spanish version) in a working population].  

PubMed

The objective of this paper is to examine the responsiveness of the Work Role Functioning Questionnaire (Spanish version) ( WRFQ-SpV) so that it could be used in evaluative studies. For this purpose a longitudinal survey was performed. Combinations of distributions-and anchor- based approaches were used. Five hypotheses were tested, examining validity of change scores. The consensus-based standards for the selection of health status measurement instruments (COSMIN) guided the study design. One hundred and two participants (mean age, 47.3 years; SD=10.3 years) completed the WRFQ-SpV twice, within a mean interval of 3.7 ( SD=1.8) months. Four hypotheses were confirmed and one was rejected . It was verified that the WRFQ-SpV was able to detect (true) changes over time. In conclusion, suggestive evidence about the possible use if the WRFQ-SpV with evaluative purposes was provided. More research is needed to examine the instrument responsiveness for groups whose health is stable or deteriorates. PMID:24851276

The influence of labels associated with anchor points of Likert-type response scales in survey questionnaires.  

PubMed

Survey questionnaires are among the most used data gathering techniques in the social sciences researchers' toolbox and many factors can influence respondents' answers on items and affect data validity. Among these factors, research has accumulated which demonstrates that verbal and numeric labels associated with item's response categories in such questionnaire may influence substantially the way in which respondents operate their choices within the proposed response format. In line with these findings, the focus of this article is to use Andrich's Rating scale model to illustrate what kind of influence the quantifier adverb "totally," used to label or emphasize extreme categories, could have on respondents' answers.

Trait emotional intelligence refers to a constellation of emotional self-perceptions located at the lower levels of personality hierarchies. In 2 studies, we sought to examine the psychometric properties of the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF; Petrides, 2009) using item response theory (IRT). Study 1 (N= 1,119, 455 men) showed that most items had good discrimination and threshold parameters and high item information values. At the global level, the TEIQue-SF showed very good precision across most of the latent trait range. Study 2 (N= 866, 432 men) used similar IRT techniques in a new sample based on the latest version of the TEIQue-SF (version 1.50). Results replicated Study 1, with the instrument showing good psychometric properties at the item and global level. Overall, the 2 studies suggest the TEIQue-SF can be recommended when a rapid assessment of trait emotional intelligence is required. PMID:20706931

Knowledge, attitudes and behavior of Italian mothers towards oral health: questionnaire validation and results of a pilot study  

PubMed Central

Summary Aims The study is focused on the analysis of knowledge, attitudes and behaviors of Italian mothers in regards to their oral health, deepening the understanding of how the initiation of habits and behaviors for a healthy lifestyle may influence the empowerment process of their children. Methods The questionnaire was composed by 14 sections and has been conducted using an online questionnaire on the mothers association’s website. Reliability analysis was tested and content validity was evaluated using Cronbach’s alpha to check internal consistency with the intention to obtain no misunderstanding results. Statistical analysis was performed through SPSS 19.0. Results The total number of the compiled questionnaires was 192. The highest value of the Cronbach’s alpha is obtainable in Section 13 (Quality of Life in relation to dental health between 8–17 years old kids) with a value of 0.998 (on 5 items). The total value of the Cronbach’s alpha considering the part of questionnaire dedicated only to the mothers that have more than 18 years old children is 0.490 on 116 items. Considering all the sections of the questionnaire on 134 items and 127 questions, we get an alpha value of 0.784. Conclusions The questionnaire for the mothers showed a good reliability in the pilot study and it seems it made good results in terms of internal coherence and validity. The online administration allowed the opportunity to optimize the data collection avoiding complications with papers and it offers potentially, a tool able to rapidly gather a vast sample in which to perfect other studies.

The responsiveness of the uterine fibroid symptom and health-related quality of life questionnaire (UFS-QOL)  

PubMed Central

Background A number of noninvasive alternatives to hysterectomy have become available as treatments for uterine fibroids. These alternative therapies, however, may not relieve all symptoms. Consequently, the need for patient-reported outcomes to assess symptom reduction of uterine fibroids has become increasingly important to evaluate the clinical success of patients who choose these alternative therapies. The purpose of the study was to examine the responsiveness of the Uterine Fibroid Symptom and Health-Related Quality of Life Questionnaire (UFS-QOL) with treatment of uterine fibroids. Methods The responsiveness of the UFS-QOL was assessed as a post-hoc analysis of patients treated with MRI-guided focused ultrasound thermal ablation (MRgFUS) for uterine fibroids. The UFS-QOL and SF-36 were completed at baseline and months 1, 3, and 6. Patient perceived overall treatment effect (OTE) was assessed at month 3, while satisfaction with treatment was collected at month 6. The responsiveness of the UFS-QOL was examined using effect sizes and change scores by patient-reported overall treatment effect and satisfaction. Results A total of 102 women with complete UFS-QOL data were included in the analysis; the mean age was 45 years and 79% were Caucasian. From baseline to 6 months, significant improvements were observed in UFS-QOL Symptom Severity and all Health-Related Quality of Life (HRQL) subscale scores (p < 0.0001). When examining change in general health status over the 6-month follow-up period, significant improvements were noted in all 8 SF-36 subscales. The UFS-QOL was highly responsive with subscale effect sizes ranging from 0.74 for Sexual Function to -1.9 for Symptom Severity. Improvements in UFS-QOL subscales were associated with patient perceptions of perceived benefit and treatment satisfaction. Conclusion The UFS-QOL is responsive to treatment for uterine fibroids and is a useful outcome measure for uterine-sparing uterine fibroid treatments. PMID:19014505

What Explains Usage of Mobile Physician-Rating Apps? Results From a Web-Based Questionnaire  

PubMed Central

Background Consumers are increasingly accessing health-related information via mobile devices. Recently, several apps to rate and locate physicians have been released in the United States and Germany. However, knowledge about what kinds of variables explain usage of mobile physician-rating apps is still lacking. Objective This study analyzes factors influencing the adoption of and willingness to pay for mobile physician-rating apps. A structural equation model was developed based on the Technology Acceptance Model and the literature on health-related information searches and usage of mobile apps. Relationships in the model were analyzed for moderating effects of physician-rating website (PRW) usage. Methods A total of 1006 randomly selected German patients who had visited a general practitioner at least once in the 3 months before the beginning of the survey were randomly selected and surveyed. A total of 958 usable questionnaires were analyzed by partial least squares path modeling and moderator analyses. Results The suggested model yielded a high model fit. We found that perceived ease of use (PEOU) of the Internet to gain health-related information, the sociodemographic variables age and gender, and the psychographic variables digital literacy, feelings about the Internet and other Web-based applications in general, patients’ value of health-related knowledgeability, as well as the information-seeking behavior variables regarding the amount of daily private Internet use for health-related information, frequency of using apps for health-related information in the past, and attitude toward PRWs significantly affected the adoption of mobile physician-rating apps. The sociodemographic variable age, but not gender, and the psychographic variables feelings about the Internet and other Web-based applications in general and patients’ value of health-related knowledgeability, but not digital literacy, were significant predictors of willingness to pay. Frequency of using apps for health-related information in the past and attitude toward PRWs, but not the amount of daily Internet use for health-related information, were significant predictors of willingness to pay. The perceived usefulness of the Internet to gain health-related information and the amount of daily Internet use in general did not have any significant effect on both of the endogenous variables. The moderation analysis with the group comparisons for users and nonusers of PRWs revealed that the attitude toward PRWs had significantly more impact on the adoption and willingness to pay for mobile physician-rating apps in the nonuser group. Conclusions Important variables that contribute to the adoption of a mobile physician-rating app and the willingness to pay for it were identified. The results of this study are important for researchers because they can provide important insights about the variables that influence the acceptance of apps that allow for ratings of physicians. They are also useful for creators of mobile physician-rating apps because they can help tailor mobile physician-rating apps to the consumers’ characteristics and needs. PMID:24918859

Prescription stimulant expectancies in recreational and medical users: results from a preliminary expectancy questionnaire.  

PubMed

Given the rise of prescription stimulant misuse, examination of effect expectancies could prove helpful. The Prescription Stimulant Expectancy Questionnaire (PSEQ) was designed to explore positive and negative prescription stimulant-related expectancies. In 2006, 157 participants nationwide completed an Internet survey of prescription stimulant use, attention-deficit/hyperactivity disorder symptoms, and expectancies. Multiple regressions demonstrate that positive, but not negative expectancies, predicted frequency of use. Recreational and medical users were classified by hierarchical cluster analysis. Recreational users reported fewer positive and negative expectancies than medical users. Implications and limitations are discussed. Future research is warranted on prescription stimulant expectancies and the utility of the PSEQ. PMID:19938932

What counselling do patients with ankylosing spondylitis receive? Results of a questionnaire survey.  

PubMed

This questionnaire survey of 71 patients with ankylosing spondylitis (members of the National Ankylosing Spondylitis Society of the UK) revealed that a substantial proportion of patients were apparently not told of several aspects of their illness by their doctors such as likely cause(s), familial clustering, role of HLA tissue typing and diet (appropriately). Only a small percentage (4.2%) were counselled to actively seek screening for close family members. As HLA B27 presence is not diagnostic of ankylosing spondylitis, and it cannot be prevented or arrested even if diagnosed at onset or early stages, routine screening of close family members cannot be justified at present.

Why German farmers have their animals vaccinated against Bluetongue virus serotype 8: Results of a questionnaire survey.  

PubMed

In response to the Bluetongue disease epidemic in 2006-2007, Germany started in 2008 a country-wide mandatory vaccination campaign. By 2009 the number of new outbreaks had decreased so that vaccination became voluntary in 2010. We conducted a questionnaire survey in cattle and sheep farms in three German federal states, namely North-Rhine Westphalia, Rhineland Palatinate and Saxony-Anhalt to estimate the vaccination uptake in 2010, the intention to vaccinate in 2011 and the main determinants of refusal or acceptance to do so. The results showed that 42.8% (40.6-45.1) of the cattle farmers and 33.8% (31.8-35.8) of the sheep farmers had their animals vaccinated in 2010, whereas 40.7% (38.5-43.0) of cattle and 37.93% (35.8-40.1) sheep farmers expressed their intention to vaccinate in 2011. The main reasons mentioned for having animals vaccinated against BTV-8 were ability to export animals, prevention of production losses, subsidized vaccination, and recommendation by the veterinarian. Motives for refusing vaccination were presumed low risk of infection, costs, absence of clinical BT symptoms, presumed negative cost-benefit ratio, and negative experience with previous vaccination events (side effects). We assume that in order to increase farmers' motivation to have their animals immunized against BTV-8, (1) the vaccination needs to be subsidized, (2) combined vaccines with several different BT serotypes or even other diseases should be available and (3) farmers need to be better informed about the safety and benefit of vaccination.

Acne as seen by adolescents: results of questionnaire study in 852 French individuals.  

PubMed

Acne can have an important psychological impact. We surveyed 852 adolescents aged 12-25 years about their knowledge of acne and its treatment in a non-medical context. The study involved a questionnaire administered to callers to a youth telephone helpline in France. Callers were categorized into those who currently had acne, those who had had acne previously, and those who had never had acne. Most respondents (66.2%) had experienced acne symptoms, which were mild in 50.2% of cases and severe in 16% of cases. Often, acne had been long-lasting (>12 months in 49.6% of cases). Many thought that gender, excess weight, eating dairy products, and physical activity did not influence acne, and that frequent washing could improve acne. Eating chocolate and snacks, smoking cigarettes, sweating, not washing, touching/squeezing spots, eating fatty foods, using make-up, pollution, and menstruation were thought to worsen acne. The majority (80.8%) did not believe acne to be a disease, but rather a normal phase of adolescence, yet 69.3% agreed it should be treated. There was a preference for topical vs. systemic treatment. Many (38.6%) of the respondents with acne had not consulted a physician. Almost two-thirds of respondents wanted more information about acne. Providing more information about acne might increase the likelihood of them consulting a physician and getting better treatment for the condition. PMID:21611685

Results of a 2011 national questionnaire for investigation of mean glandular dose from mammography in Japan.  

PubMed

Diagnostic reference levels (DRLs) for mammography have yet to be created in Japan. A national questionnaire investigation into radiographic conditions in Japan was carried out for the purpose of creating DRLs. Items investigated included the following: tube voltage; tube current; current-time product; source-image distance; craniocaudal view; automatic exposure control (AEC) settings; name of mammography unit; image receptor system (computed radiography (CR), flat panel detector (FPD), or film/screen (F/S)); and supported or unsupported monitor diagnosis (including monitor resolution). Estimation of the mean glandular dose (MGD) for mammography was performed and compared with previous investigations. The MGD was 1.58(0.48) mGy, which did not significantly differ from a 2007 investigation. In relation to image receptors, although no difference in average MGD values was observed between CR and FPD systems, F/S systems had a significantly decreased value compared to both CR and FPDs. Concerning digital systems (FPDs), the MGD value of the direct conversion system was significantly higher than the indirect conversion system. No significant difference in MGD value was evident concerning type of monitor diagnosis for either the CR or the FPD digital systems; however, hard copies were used more often in CR. No significant difference in the MGD value was found in relation to monitor resolution. This report suggests ways to lower the doses patients undergoing mammography receive in Japan, and serves as reference data for 4.2 cm compressed breast tissue of 50% composition DRLs. Furthermore, our findings suggest that further optimisation of FPD settings can promote a reduction in the MGD value. PMID:24334729

Validity of a questionnaire measuring the world health organization concept of health system responsiveness with respect to perinatal services in the dutch obstetric care system.  

PubMed

BackgroundThe concept of responsiveness, introduced by the World Health Organization (WHO), addresses non-clinical aspects of health service quality that are relevant regardless of provider, country, health system or health condition. Responsiveness refers to ¿aspects related to the way individuals are treated and the environment in which they are treated¿ during health system interactions. This paper assesses the psychometric properties of a newly developed responsiveness questionnaire dedicated to evaluating maternal experiences of perinatal care services, called the Responsiveness in Perinatal and Obstetric Health Care Questionnaire (ReproQ), using the eight-domain WHO concept.MethodsThe ReproQ was developed between October 2009 and February 2010 by adapting the WHO Responsiveness Questionnaire items to the perinatal care context. The psychometric properties of feasibility, construct validity, and discriminative validity were empirically assessed in a sample of Dutch women two weeks post partum.ResultsA total of 171 women consented to participation. Feasibility: the interviews lasted between 20 and 40 minutes and the overall missing rate was 8%. Construct validity: mean Cronbach¿s alphas for the antenatal, birth and postpartum phase were: 0.73 (range 0.57-0.82), 0.84 (range 0.66-0.92), and 0.87 (range 0.62-0.95) respectively. The item-own scale correlations within all phases were considerably higher than most of the item-other scale correlations. Within the antenatal care, birth care and post partum phases, the eight factors explained 69%, 69%, and 76% of variance respectively. Discriminative validity: overall responsiveness mean sum scores were higher for women whose children were not admitted. This confirmed the hypothesis that dissatisfaction with health outcomes is transferred to their judgement on responsiveness of the perinatal services.ConclusionsThe ReproQ interview-based questionnaire demonstrated satisfactory psychometric properties to describe the quality of perinatal care in the Netherlands, with the potential to discriminate between different levels of quality of care. In view of the relatively small sample, further testing and research is recommended. PMID:25465053

Government/industry response to questionnaire on space mechanisms/tribology technology needs  

NASA Technical Reports Server (NTRS)

President Bush has proposed that the U.S. undertake an ambitious mission of manned and robotic exploration of the solar system. This mission will require advanced mechanical moving components, such as bearings, gears, seals, lubricants, etc. There has been concern in the NASA community that the current technology level in these mechanical component/tribology areas may not be adequate to meet the goals of such a mission. To attempt to answer this, NASA-Lewis has sent out a questionnaire to government and industry workers (who have been involved in space mechanism research, design, and implementation) to ask their opinion if the current space mechanisms technology (mechanical components/tribology) is adequate to meet future NASA Missions needs and goals. If they deemed that the technology base inadequate, they were asked to specify the areas of greatest need. The unedited remarks of those who responded to the survey are presented.

The use of intraosseous anesthesia among endodontists: results of a questionnaire.  

PubMed

The purpose of this study was to investigate the use of supplemental intraosseous (IO) anesthesia among endodontists in the United States. The study also looked at the types of anesthetic solutions commonly used for IO anesthesia and in which diagnostic conditions IO anesthesia is used. A Web-based survey of 2,528 active members of the American Association of Endodontists was sent out by e-mail. Data from 833 respondents were collected with a response rate of 33%. It was discovered that 94.77% of the respondents used some form of IO anesthesia, with the periodontal ligament injection (PDL) being the most commonly administered (49.78%). Symptomatic irreversible pulpitis is the pulpal diagnosis for which respondents most often use some form of IO anesthesia (61.99%), and 2% lidocaine with epinephrine 1:100,000 is the most common anesthetic solution used in IO anesthesia (37.62%). Although more than half of the respondents use some form of IO anesthesia more than twice a week, newer IO anesthesia delivery systems such as Stabident (Fairfax Dental, San Francisco, CA) and X-Tip (Dentsply International, Johnson City, TN) are used less often than the PDL injection.

Measuring Client Experiences in Maternity Care under Change: Development of a Questionnaire Based on the WHO Responsiveness Model  

PubMed Central

Background Maternity care is an integrated care process, which consists of different services, involves different professionals and covers different time windows. To measure performance of maternity care based on clients' experiences, we developed and validated a questionnaire. Methods and Findings We used the 8-domain WHO Responsiveness model, and previous materials to develop a self-report questionnaire. A dual study design was used for development and validation. Content validity of the ReproQ-version-0 was determined through structured interviews with 11 pregnant women (?28 weeks), 10 women who recently had given birth (?12 weeks), and 19 maternity care professionals. Structured interviews established the domain relevance to the women; all items were separately commented on. All Responsiveness domains were judged relevant, with Dignity and Communication ranking highest. Main missing topic was the assigned expertise of the health professional. After first adaptation, construct validity of the ReproQ-version-1 was determined through a web-based survey. Respondents were approached by maternity care organizations with different levels of integration of services of midwives and obstetricians. We sent questionnaires to 605 third trimester pregnant women (response 65%), and 810 women 6 weeks after delivery (response 55%). Construct validity was based on: response patterns; exploratory factor analysis; association of the overall score with a Visual Analogue Scale (VAS), known group comparisons. Median overall ReproQ score was 3.70 (range 1–4) showing good responsiveness. The exploratory factor analysis supported the assumed domain structure and suggested several adaptations. Correlation of the VAS rating and overall ReproQ score (antepartum, postpartum) supported validity (r = 0.56; 0.59, p<0.001 Spearman's correlation coefficient). Pre-stated group comparisons confirmed the expected difference following a good vs. adverse birth outcome. Fully integrated organizations performed slightly better (median = 3.78) than less integrated organizations (median = 3.63; p<0.001). Participation rate of women with a low educational level and/or a non-western origin was low. Conclusions The ReproQ appears suitable for assessing quality of maternity care from the clients' perspective. Recruitment of disadvantaged groups requires additional non-digital approaches.

Initial pain management plans in response to severe pain indicators on oncology clinic previsit questionnaires  

PubMed Central

BACKGROUND: The issue of how to address patient pain in the outpatient setting remains challenging. At the London Regional Cancer Program (London, Ontario), patients complete the Edmonton Symptom Assessment System (ESAS) before most visits. OBJECTIVES: To perform a chart review assessing the frequency and, if applicable, the type of a clinical care plan that was developed if a patient indicated pain ?7 on a 10-point scale. METHODS: The charts of 100 eligible sequential outpatient visits were reviewed and the initial pain management approaches were documented. RESULTS: Between December 2011 and May 2012, visits by 7265 unique patients included 100 eligible visits (pain ?7 of 10). In 83 cases, active pain management plans, ranging from counselling to hospital admission, were proposed. Active pain management plans were more likely if the cause was believed to be cancer/treatment related: 63 of 65 (96.9%) versus 20 of 35 (57.1%, noncancer/unknown pain cause); P<0.001. There were no differences depending on cancer treatment intent or medical service. CONCLUSIONS: Active pain management plans were documented in 83% of visits. However, patients who reported severe pain that was assessed as benign or unknown in etiology received intervention less frequently, perhaps indicating that oncologists either consider themselves less responsible for noncancer pain, or believe that pain chronicity may lead to a higher ESAS pain score without indicating a need for acute intervention. Further study is needed to determine the subsequent effect of the care plans on patient-reported ESAS pain scores at future clinic visits. PMID:25101336

[Is there a link between the mercury release of amalgam fillings and the results of psychological questionnaires?].  

PubMed

Amalgam as a dental filling material shows excellent material property. It is fast, easy and economical to implement. Evidence for the release of mercury (Hg) from amalgam fillings was given in a number of studies. Mercury release from amalgam dental fillings is often claimed to be a possible cause of unspecific chronic symptoms such as chronic fatigue, headache and migraine. The present study explored relationships between the mercury release from amalgam fillings and the results of psychological questionnaires. The urine of 126 men and women in the age range of 16 to 76 years was examined. 45 participants did not present any amalgam restorations. The mercury released into the urine was measured by using cold-vapour AAS. The results of the study show that chronic mercury exposure, in the low concentration range, is not linked with chronic subjective symptoms. PMID:20052827

[Changes of working responsibilities and intentions of industrial physicians who are graduates of University of Occupational and Environmental Health, Japan, in 2001 and 2008 questionnaire analyses].  

PubMed

To investigate the working responsibilities and intentions of industrial physicians who are graduates of University of Occupational and Environmental Health, Japan (UOEH), we performed a questionnaire survey in 2008 and compared the results with those of 2001. To industrial physicians belonging to a company or occupational health organization, we dispatched a questionnaire and asked them to return it with an answer. The items to investigate included their careers and working activities and their intentions to their responsibilities. We obtained the following results. 1. The dissatisfaction with salary and official position was mostly reduced to 24.7% from 29.2% and 19.7% from 29.9%. 2. The practical duty of medical examination of workers and the subsequent management was decreased to 51.5% from 74.7%, while mental health support and the advice on severe health issues such as excess work death were increased to 85.6% from 54.5% and 32.4% from 22.1%. 3. Concerning the working status of industrial physicians, the ratio of the answer of "The industrial physician duties are not positively evaluated by his or her company" was decreased to 23.1% from 32.5%. The investigation of 2008 revealed that the situation of UOEH graduated industrial physicians was substantially improved concerning the dissatisfaction with salary and official position, as compared with the study of 7 years before.

The post-investigation questionnaire (PIO-R): a practical instrument to assess erectile response after intracavernous injection.  

PubMed

Erectile response to intracavernous pharmacological stimulation is highly susceptible to stress and anxiety provoked by the test-situation. To reduce false-positive diagnosis of veno-occlusive dysfunction and to limit the need for high-dosage pharmacotesting, we developed the Post-Investigation Questionnaire (PIQ-R), a self-report instrument to assess erectile response to pharmacological stimulation after the patient has left the office. In this study veno-occlusive sufficiency was not demonstrated in 80 of 105 patients with erectile dysfunction at the time of pharmaco-penile duplex ultrasonography. PIQ-R detected sufficient erectile response in 40 of these patients, thus reducing false-positive diagnosis of veno-occlusive dysfunction by 50%. We also found that reports of sexual activity after investigation increased interest in auto-injection therapy. PIQ-R is a practical self-report measure to assess erectile response after clinical pharmacotesting, and to more carefully select patients for auto-injection therapy. PMID:8858391

Determinants of patient satisfaction with hospital health care in psychiatry: results based on the SATISPSY-22 questionnaire  

PubMed Central

Background The aim of our study was to identify patient- and care-related factors that are associated with patients’ satisfaction with psychiatric hospital care, using a specific, self-administered questionnaire based exclusively on the patient’s point of view: the Satisfaction with Psychiatry Care Questionnaire-22 (SATISPSY-22). Methods This cross-sectional study was conducted in the psychiatric departments of two French public university teaching hospitals. The data collected included sociodemographic information, clinical characteristics, care characteristics, and the SATISPSY-22. A multivariate analysis using multiple linear regressions was performed to determine the variables potentially associated with satisfaction levels. Results Two hundred seventy patients were enrolled in our study. Only one moderate association was found between satisfaction and sociodemographic characteristics: the personal experience dimension with age (?=0.15). Clinical improvement was moderately associated with higher global satisfaction (?=?0.15), higher satisfaction with quality of care (?=?0.19), and higher satisfaction with food (?=?0.18). Stronger associations with satisfaction were found for care characteristics, particularly the therapeutic alliance with all of the satisfaction dimensions (?, 0.20–0.43) except food, and for seclusion with global satisfaction (?=?0.33) and personal experience (?=?0.32). Patients with previous hospitalization also had a higher level of satisfaction with quality of care compared with patients who were admitted for the first time (?=?0.15). Conclusion This study has identified a number of potential determinants of satisfaction. The therapeutic relationship and seclusion were the most important features associated with a patient’s satisfaction. These factors might be amenable through intervention, which, in turn, might be expected to improve satisfaction, patients’ management, and health outcomes in psychiatric hospitals. PMID:25368515

The Questionnaire for Urinary Incontinence Diagnosis (QUID): Validity and Responsiveness to Change in Women Undergoing Non-Surgical Therapies for Treatment of Stress Predominant Urinary Incontinence  

PubMed Central

Aims The Questionnaire for Urinary Incontinence Diagnosis (QUID), a 6-item urinary incontinence (UI) symptom questionnaire, was developed and validated to distinguish stress and urge UI. This study’s objective was to evaluate QUID validity and responsiveness when used as a clinical trial outcome measure. Methods Participants enrolled in a multi-center trial of non-surgical therapy (continence pessary, pelvic floor muscle training or combined) for stress-predominant UI completed baseline and 3-month diaries, the Urinary Distress Inventory (UDI) and QUID. Data from all treatment groups were pooled. QUID internal consistency (Cronbach’s ?) and convergent/discriminant validity (Pearson correlations) were evaluated. Responsiveness to change was assessed with 3-month score outcomes and distribution-based measurements. Results 444 women (mean age 50) were enrolled with stress (N=200) and mixed (N=244) UI; 344 had 3-month data. Baseline QUID Stress and Urge scores (both scaled 0-15, larger values indicating worse UI) were 8.4 ± 3.2 and 4.5 ± 3.3, respectively. Internal consistency of QUID Total, Stress and Urge scores was 0.75, 0.64 and 0.87, respectively. QUID Stress scores correlated moderately with UDI-Stress scores (r=0.68, p<0.0001) and diary stress UI episodes (r=0.41, p<0.0001). QUID Urge scores correlated moderately with UDI-Irritative scores (r=0.68, p<0.0001) and diary urge UI episodes (r=0.45, p<0.0001). 3-month QUID Stress and Urge scores improved (4.1 ± 3.4 and 2.2 ± 2.7, both p<0.0001). QUID Stress score Effect Size (1.3) and Standardized Response Mean (1.2) suggested a large change after therapy. Conclusion The QUID has acceptable psychometric characteristics and may be used as a UI outcome measure in clinical trials. PMID:19787711

How to compare scores from different depression scales: equating the Patient Health Questionnaire (PHQ) and the ICD-10-Symptom Rating (ISR) using Item Response Theory.  

PubMed

A wide range of questionnaires for measuring depression are available. Item Response Theory models can help to evaluate the questionnaires exceeding the boundaries of Classical Test Theory and provide an opportunity to equate the questionnaires. In this study after checking for unidimensionality, a General Partial Credit Model was applied to data from two different depression scales [Patient Health Questionnaire (PHQ-9) and ICD-10-Symptom Rating (ISR)] obtained in clinical settings from a consecutive sample, including 4517 observations from a total of 2999 inpatients and outpatients of a psychosomatic clinic. The precision of each questionnaire was compared and the model was used to transform scores based on the assumed underlying latent trait. Both instruments were constructed to measure the same construct and their estimates of depression severity are highly correlated. Our analysis showed that the predicted scores provided by the conversion tables are similar to the observed scores in a validation sample. The PHQ-9 and ISR depression scales measure depression severity across a broad range with similar precision. While the PHQ-9 shows advantages in measuring low or high depression severity, the ISR is more parsimonious and also suitable for clinical purposes. Furthermore, the equation tables derived in this study enhance the comparability of studies using either one of the instruments, but due to substantial statistical spread the comparison of individual scores is imprecise.

A reliable, valid and responsive questionnaire to score the impact of knee complaints on work following total knee arthroplasty: the WORQ.  

PubMed

The Work, Osteoarthritis or joint-Replacement Questionnaire (WORQ) was developed to assess physical difficulty experienced in work before or following total knee arthroplasty (TKA). Thirteen questions were designed. The WORQ was tested for internal consistency by factor analysis, internal reliability (Crohnbach's ?), and construct validity. A test-retest reproducibility was performed for analyzing standard error of measurement (SEM agreement), reliability (ICC) and smallest detectable change (SDC) in individuals and groups. Lastly responsiveness (standardized response means [SRM]), floor and ceiling effects and interpretability (minimal important change [MIC]) were analyzed. It is shown that the WORQ is a reliable, valid and responsive questionnaire that can be used to evaluate the impact of knee complaints following TKA on patients' ability to work. PMID:24581898

Validity and responsiveness of EuroQol-5 dimension (EQ-5D) versus Short Form-6 dimension (SF-6D) questionnaire in chronic pain  

PubMed Central

Background Assessments of health-related quality of life and particularly utility values are important components of health economic analyses. Several instruments have been developed to measure utilities. However no consensus has emerged regarding the most appropriate instrument within a therapeutic area such as chronic pain. The study compared two instruments – EQ-5D and SF-6D – for their performance and validity in patients with chronic pain. Methods Pooled data from three randomised, controlled clinical trials with two active treatment groups were used. The included patients suffered from osteoarthritis knee pain or low back pain. Differences between the utility measures were compared in terms of mean values at baseline and endpoint, Bland–Altman analysis, correlation between the dimensions, construct validity, and responsiveness. Results The analysis included 1977 patients, most with severe pain on the Numeric Rating Scale. The EQ-5D showed a greater mean change from baseline to endpoint compared with the SF-6D (0.43 to 0.58 versus 0.59 to 0.64). Bland–Altman analysis suggested the difference between two measures depended on the health status of a patient. Spearmans rank correlation showed moderate correlation between EQ-5D and SF-6D dimensions. Construct validity showed both instruments could differentiate between patient subgroups with different severities of adverse events and analgesic efficacies but larger differences were detected with the EQ-5D. Similarly, when anchoring the measures to a disease-specific questionnaire – Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) – both questionnaires could differentiate between WOMAC severity levels but the EQ-5D showed greater differences. Responsiveness was also higher with the EQ-5D and for the subgroups in which improvements in health status were expected or when WOMAC severity level was reduced the improvements with EQ-5D were higher than with SF-6D. Conclusions This analysis showed that the mean EQ-5D scores were lower than mean SF-6D scores in patients with chronic pain. EQ-5D seemed to have higher construct validity and responsiveness in these patients. PMID:23815777

PubMed

We sent out questionnaires to examine how caregivers, who are involved in caring home dementia patients, effectively reduce their stresses by blogging. A total of 39 caregivers(13 males and 26 females)filled out a questionnaire(write-in free descriptive type)by E-mail. What was it that you gained from blogging to reduce a stress from the work ? The responses to that question were: (1) social support, (2) coping with stress, and (3) perception of the event. These answers appeared to be agreed with the crisis theory of Aguilera. In the situation where a lot of stresses were involved, it was clear that blogging was an effective way to reduce a stress for caregivers who were involved in caring dementia patients at home.

Survey of construction workers repeatedly exposed to chlorine over a three to six month period in a pulpmill: II. Follow up of affected workers by questionnaire, spirometry, and assessment of bronchial responsiveness 18 to 24 months after exposure ended.  

PubMed Central

OBJECTIVE--The aim was to determine the prevalence of persistent respiratory symptoms and bronchial hyper-responsiveness due to reactive airways dysfunction syndrome in a population of construction workers at moderate to high risk of developing the syndrome, at an interval of 18 to 24 months after multiple exposures to chlorine gas during renovations to a pulp and paper mill. DESIGN AND PARTICIPANTS--71 of 289 exposed workers (25%) were identified on the basis of an exposure and the onset of respiratory symptoms shortly after this event (moderate to high risk). A standardised respiratory questionnaire was first presented, followed by spirometry and a methacholine inhalation test on those whose questionnaire suggested the persistence of respiratory symptoms. RESULTS--64 of 71 (90%) subjects completed the respiratory questionnaire at the time of the follow up. The questionnaire suggested a persistence of respiratory symptoms in 58 of the 64 workers (91%). Of the 58 subjects, 51 underwent spirometry and assessment of bronchial responsiveness. All of them used bronchodilators as required (not regularly) and four required inhaled anti-inflammatory preparations. Sixteen had bronchial obstruction (forced expiratory volume in one second) (FEV1 < 80% predicted) and 29 showed significant bronchial hyper-responsiveness. CONCLUSION--Of the subjects (n = 71) who were at moderate to high risk of developing reactive airways dysfunction syndrome after being exposed to chlorine and were seen 18 to 24 months after exposure ended, 58 (82%) still had respiratory symptoms, 16 (23%) had evidence of bronchial obstruction, and 29 (41%) had bronchial hyper-responsiveness.

[Evaluation of the nutritional status and feeding patterns of 3-7 year old children --results of a questionnaire].  

PubMed

Questionnaire studies on feeding patterns and nutritional status of 822 pre-school children (age 3-7) in different regions of Poland were performed between June 1999 and January 2000. Nutritional status was evaluated on the basis of anthropometric indices - height, body weight, body mass index (BMI) and BMI z-score. The mode of feeding was evaluated on the basis of recall of 24-hours menus. Average daily food rations and their nutritional value were calculated from the questionnaires data. Quantity and number of meals were also evaluated. In a group of 402 boys the average height was between 75-90 percentiles and body mass (50-75 percentiles). In 420 girls the average height was about the 90 percentile (age 3-4) and between 75-90 percentiles (age 5-7). The study showed that normal BMI z-score was found in 75% of children, underweight in 16.5% overweight and obesity in 8.5%. Feeding patterns showed great than differences. It was found that meat, fat, sweets and sugar content in daily food rations exceeded the recommended for pre-school children, but the vegetables intake was lower than recommended. Vitamins A and C deficiency in average daily rations didn't occur. The fat intake provided 36% of total energy, whereas carbohydrates (without lactose and starch) - about 20%. This can have inhibitory effect on microelements (Fe, Zn) absorption. Attention must be paid to the choice of products and the wrong distribution of total energy intake in daily rations. The habits of snack eating between the meals were reported in 91% of children. These snacks consisted of fruits, chips, french fries, sweets and sandwiches. These products provides 232 kcal +/- 171 kcal/day. PMID:11381151

Planck 2013 results. IX. HFI spectral response  

E-print Network

The Planck HFI spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment prior to launch. The main goal of the spectral transmission tests is to measure the relative spectral response (including the level of out-of-band signal rejection) of all HFI detectors to a known source of electromagnetic radiation individually. This was determined by measuring the output of all detection channels for radiation propagated through a continuously scanned polarizing Fourier transform spectrometer. As there is no on-board spectrometer within HFI, the ground-based spectral response experiments provide the definitive data set for the relative spectral calibration of the HFI.

Planck 2013 results. IX. HFI spectral response  

NASA Astrophysics Data System (ADS)

The Planck High Frequency Instrument (HFI) spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment prior to launch. The main goal of the spectral transmission tests was to measure the relative spectral response (includingthe level of out-of-band signal rejection) of all HFI detectors to a known source of electromagnetic radiation individually. This was determined by measuring the interferometric output of a continuously scanned Fourier transform spectrometer with all HFI detectors. As there is no on-board spectrometer within HFI, the ground-based spectral response experiments provide the definitive data set for the relative spectral calibration of the HFI. Knowledge of the relative variations in the spectral response between HFI detectors allows for a more thorough analysis of the HFI data. The spectral response of the HFI is used in Planck data analysis and component separation, this includes extraction of CO emission observed within Planck bands, dust emission, Sunyaev-Zeldovich sources, and intensity to polarization leakage. The HFI spectral response data have also been used to provide unit conversion and colour correction analysis tools. While previous papers describe the pre-flight experiments conducted on the Planck HFI, this paper focusses on the analysis of the pre-flight spectral response measurements and the derivation of data products, e.g. band-average spectra, unit conversion coefficients, and colour correction coefficients, all with related uncertainties. Verifications of the HFI spectral response data are provided through comparisons with photometric HFI flight data. This validation includes use of HFI zodiacal emission observations to demonstrate out-of-band spectral signal rejection better than 108. The accuracy of the HFI relative spectral response data is verified through comparison with complementary flight-data based unit conversion coefficients and colour correction coefficients. These coefficients include those based upon HFI observations of CO, dust, and Sunyaev-Zeldovich emission. General agreement is observed between the ground-based spectral characterization of HFI and corresponding in-flight observations, within the quoted uncertainty of each; explanations are provided for any discrepancies.

Paper to Electronic Questionnaires: Effects on Structured Questionnaire Forms  

NASA Technical Reports Server (NTRS)

With the use of computers, paper questionnaires are being replaced by electronic questionnaires. The formats of traditional paper questionnaires have been found to effect a subject's rating. Consequently, the transition from paper to electronic format can subtly change results. The research presented begins to determine how electronic questionnaire formats change subjective ratings. For formats where subjects used a flow chart to arrive at their rating, starting at the worst and middle ratings of the flow charts were the most accurate but subjects took slightly more time to arrive at their answers. Except for the electronic paper format, starting at the worst rating was the most preferred. The paper and electronic paper versions had the worst accuracy. Therefore, for flowchart type of questionnaires, flowcharts should start at the worst rating and work their way up to better ratings.

Self-reports of HIV risk factors by patients at a sexually transmitted disease clinic: audio vs written questionnaires.  

PubMed Central

OBJECTIVES. The purpose of this study was to determine how the method of assessment affects patient report of human immunodeficiency virus (HIV) risks. METHODS. Patients at a sexually transmitted disease clinic randomly received either a written self-administered questionnaire or an audio self-administered questionnaire delivered by cassette player and headset. These questionnaires were followed by face-to-face interviews. RESULTS. Audio questionnaires had fewer missing responses than written questionnaires. Audio questionnaires also identified more unprotected vaginal intercourse and sexual partners suspected or known to have HIV infection or acquired immunodeficiency syndrome than did written questionnaires. Although both the audio and written questionnaires identified more risks than the face-to-face interviews, the difference in the mean number of reported risks between the audio questionnaires and the face-to-face interviews was greater than that between the written questionnaires and the face-to-face interviews. CONCLUSIONS. Audio questionnaires may obtain more complete data and identify more HIV risk than written questionnaires. Research is warranted about whether audio questionnaires overcome barriers to the completion and accuracy of HIV risk surveys. This study emphasizes the need to elucidate the relative strengths and weaknesses of written questionnaires, audio questionnaires, and face-to-face interviews for HIV risk assessment. PMID:8179044

Conversion of Questionnaire Data  

SciTech Connect

During the survey, respondents are asked to provide qualitative answers (well, adequate, needs improvement) on how well material control and accountability (MC&A) functions are being performed. These responses can be used to develop failure probabilities for basic events performed during routine operation of the MC&A systems. The failure frequencies for individual events may be used to estimate total system effectiveness using a fault tree in a probabilistic risk analysis (PRA). Numeric risk values are required for the PRA fault tree calculations that are performed to evaluate system effectiveness. So, the performance ratings in the questionnaire must be converted to relative risk values for all of the basic MC&A tasks performed in the facility. If a specific material protection, control, and accountability (MPC&A) task is being performed at the 'perfect' level, the task is considered to have a near zero risk of failure. If the task is performed at a less than perfect level, the deficiency in performance represents some risk of failure for the event. As the degree of deficiency in performance increases, the risk of failure increases. If a task that should be performed is not being performed, that task is in a state of failure. The failure probabilities of all basic events contribute to the total system risk. Conversion of questionnaire MPC&A system performance data to numeric values is a separate function from the process of completing the questionnaire. When specific questions in the questionnaire are answered, the focus is on correctly assessing and reporting, in an adjectival manner, the actual performance of the related MC&A function. Prior to conversion, consideration should not be given to the numeric value that will be assigned during the conversion process. In the conversion process, adjectival responses to questions on system performance are quantified based on a log normal scale typically used in human error analysis (see A.D. Swain and H.E. Guttmann, 'Handbook of Human Reliability Analysis with Emphasis on Nuclear Power Plant Applications,' NUREG/CR-1278). This conversion produces the basic event risk of failure values required for the fault tree calculations. The fault tree is a deductive logic structure that corresponds to the operational nuclear MC&A system at a nuclear facility. The conventional Delphi process is a time-honored approach commonly used in the risk assessment field to extract numerical values for the failure rates of actions or activities when statistically significant data is absent.

"Would you accept having your DNA profile inserted in the National Forensic DNA database? Why?" Results of a questionnaire applied in Portugal.  

PubMed

The creation and expansion of forensic DNA databases might involve potential threats to the protection of a range of human rights. At the same time, such databases have social benefits. Based on data collected through an online questionnaire applied to 628 individuals in Portugal, this paper aims to analyze the citizens' willingness to donate voluntarily a sample for profiling and inclusion in the National Forensic DNA Database and the views underpinning such a decision. Nearly one-quarter of the respondents would indicate 'no', and this negative response increased significantly with age and education. The overriding willingness to accept the inclusion of the individual genetic profile indicates an acknowledgement of the investigative potential of forensic DNA technologies and a relegation of civil liberties and human rights to the background, owing to the perceived benefits of protecting both society and the individual from crime. This rationale is mostly expressed by the idea that all citizens should contribute to the expansion of the National Forensic DNA Database for reasons that range from the more abstract assumption that donating a sample for profiling would be helpful in fighting crime to the more concrete suggestion that everyone (criminals and non-criminals) should be in the database. The concerns with the risks of accepting the donation of a sample for genetic profiling and inclusion in the National Forensic DNA Database are mostly related to lack of control and insufficient or unclear regulations concerning safeguarding individuals' data and supervising the access and uses of genetic data. By providing an empirically-grounded understanding of the attitudes regarding willingness to donate voluntary a sample for profiling and inclusion in a National Forensic DNA Database, this study also considers the citizens' perceived benefits and risks of operating forensic DNA databases. These collective views might be useful for the formation of international common ethical standards for the development and governance of DNA databases in a framework in which the citizens' perspectives are taken into consideration.

I like it when my partner holds my hand: development of the Responses and Attitudes to Support during Pain questionnaire (RASP)  

PubMed Central

Social support can have beneficial effects on psychological and physiological well-being. During acute bodily pain, however, the effects of social support on pain are mixed. This variability may be due to the multifaceted nature of both pain and social support, as well as individual differences. In this paper, we present the development, psychometric assessment, and initial validation of the first self-report measure designed to address this variability in the general population; the Responses and Attitudes to Support during Pain questionnaire (RASP). The RASP includes questions on social support from the romantic partner as well as healthcare professionals (HCPs) and addresses different types of social support and pain responses. The development and validation of the RASP comprised four studies. In Study 1, a preliminary RASP version was completed by 179 healthy individuals regarding any type of acute pain. In Study 2, the reduced RASP was completed by 256 women with experiences of menstrual pain. Principal component analysis indicated a 22-item solution with five underlying dimensions reflecting General Partner Support, Emotional Support from HCPs, Anxiety in the Context of HCPs, Pain Behaviors during Partner Support, and Distraction by the Partner. Construct validity was assessed using a measure of adult attachment style. The RASP showed good validity and test-retest reliability. In Study 3, the 5-factor model received initial support through confirmatory factor analysis in a new sample of 120 individuals with recent musculoskeletal pain. Study 4 provided additional validation of the RASP in a sample of 180 individuals responding in reference to acute back pain. Overall, the RASP is a valid and reliable measure for assessing individual differences in attitudes and responses to social support in relation to acute pain. PMID:25285083

Psychometric evaluation of the SF-36 (v.2) questionnaire in a probability sample of Brazilian households: results of the survey Pesquisa Dimensões Sociais das Desigualdades (PDSD), Brazil, 2008  

PubMed Central

Background In Brazil, despite the growing use of SF-36 in different research environments, most of the psychometric evaluation of the translated questionnaire was from studies with samples of patients. The purpose of this paper is to examine if the Brazilian version of SF-36 satisfies scaling assumptions, reliability and validity required for valid interpretation of the SF-36 summated ratings scales in the general population. Methods 12,423 individuals and their spouses living in 8,048 households were selected from a stratified sample of all permanent households along the country to be interviewed using the Brazilian SF-36 (version 2). Psychometric tests were performed to evaluate the scaling assumptions based on IQOLA methodology. Results Data quality was satisfactory with questionnaire completion rate of 100%. The ordering of the item means within scales clustered as hypothesized. All item-scale correlations exceeded the suggested criteria for reliability with success rate of 100% and low floor and ceiling effects. All scales reached the criteria for group comparison and factor analysis identified two principal components that jointly accounted for 67.5% of the total variance. Role emotional and vitality were strongly correlated with physical and mental components, respectively, while social functioning was moderately correlated with both components. Role physical and mental health scales were, respectively, the most valid measures of the physical and mental health component. In the comparisons between groups that differed by the presence or absence of depression, subjects who reported having the disease had lower mean scores in all scales and mental health scale discriminated best between the two groups. Among those healthy and with one, two or three and more chronic illness, the average scores were inverted related to the number of diseases. Body pain, general health and vitality were the most discriminating scales between healthy and diseased groups. Higher scores were associated with individuals of male sex, age below 40 years old and high schooling. Conclusions The Brazilian version of SF-36 performed well and the findings suggested that it is a reliable and valid measure of health related quality of life among the general population as well as a promising measure for research on health inequalities in Brazil.

Towards socially inclusive research: An evaluation of telephone questionnaire administration in a multilingual population  

PubMed Central

Background Missing data may bias the results of clinical trials and other studies. This study describes the response rate, questionnaire responses and financial costs associated with offering participants from a multilingual population the option to complete questionnaires over the telephone. Methods Design: Before and after study of two methods of questionnaire completion. Participants and Setting: Seven hundred and sixty five pregnant women from 25 general practices in two UK inner city Primary Care Trusts (PCTs) taking part in a cluster randomised controlled trial of offering antenatal sickle cell and thalassaemia screening in primary care. Two hundred and four participants did not speak English. Sixty one women were offered postal questionnaire completion only and 714 women were offered a choice of telephone or postal questionnaire completion. Outcome measures: (i) Proportion of completed questionnaires, (ii) attitude and knowledge responses obtained from a questionnaire assessing informed choice. Results The response rate from women offered postal completion was 26% compared with 67% for women offered a choice of telephone or postal completion (41% difference 95% CI Diff 30 to 52). For non-English speakers offered a choice of completion methods the response rate was 56% compared with 71% for English speakers (95% CI Diff 7 to 23). No difference was found for knowledge by completion method, but telephone completion was associated with more positive attitude classifications than postal completion (87 vs 96%, 95% CI diff 0.006 to 15). Compared with postal administration the additional costs associated with telephone administration were £3.90 per questionnaire for English speakers and £71.60 per questionnaire for non English speakers. Conclusion Studies requiring data to be collected by questionnaire may obtain higher response rates from both English and non-English speakers when a choice of telephone or postal administration (and where necessary, an interpreter)is offered compared to offering postal administration only. This approach will, however, incur additional research costs and uncertainty remains about the equivalence of responses obtained from the two methods. PMID:18237377

Do we practice evidence based medicine with regard to drain usage in knee arthroplasty? Results of a questionnaire of BASK members.  

PubMed

Clinical governance requires our clinical practice to be evidence based. We wished to see if British Orthopaedic surgeons are using the current evidence with regards to the use of drains in knee arthroplasty. A questionnaire was faxed to all UK members of BASK to ascertain their current practice regarding the use of drains in knee arthroplasty and the rationale for their drain policy. The study suggests that the majority of practising members of BASK do not practice evidence based medicine with regard to the use of drains in knee arthroplasty. PMID:14629946

[Results of questionnaire on decision-making to treat advanced non-small cell lung cancer based on American and European practical guidelines].  

PubMed

During 2009, practical routine guidelines for advanced non-small cell lung cancer used in Europe or USA were updated because the clinical benefits of molecular target agents were confirmed through several pivotal clinical trials. These molecular target agents appeared in guidelines which became available in Japan by the end of 2009. We made a questionnaire for decision-making to treat advanced non-small cell lung cancer based on these practical guidelines. Oncologists of lung cancer working in the Shinjuku area of Tokyo in Japan were eligible. Between March 15th and April 9th in 2010, 28 oncologists from 12 departments in 7 hospitals completed this questionnaire. Most of them made the global standard decision-making according to the new guidelines, including new proposals such as usage of epidermal growth factor receptor-tyrosine kinase inhibitors. There were 3 differences from the guidelines. 1)Platinum doublets were selected even in 2nd- or 3rd-line treatment because of the expected tumor shrinkage. 2)Single cytotoxic agents were selected even for 3rd-line treatment. The tendency of a backward shift in decision-making was observed. 3)There were few selections of regimens including bevacizumab because of medical systems such as DPC(Diagnosis Procedure Combination)that is Japanese DRG(Diagnosis-Related Group)/PPS(Prospective Payment System).

OBJECTIVE: To investigate the psychometric properties of a cardiovascular extension of an existing utility-based quality of life questionnaire (Health Measurement Questionnaire). The new instrument has been named the Utility Based Quality of life--Heart questionnaire, or UBQ-H. DESIGN: Explored the test-retest reliability, construct validity, and responsiveness of the UBQ-H. PATIENTS: A sample of 322 patients attending cardiac outpatient clinics were recruited from two large metropolitan teaching hospitals. A second sample of 1112 patients taking part in the LIPID trial was also used to investigate the validity and responsiveness of the UBQ-H. RESULTS: Ninety per cent of all UBQ-H questionnaires were returned, and item completion rates were high (median of less than 1% missing or N/A answers). Cronbach's alpha measure of internal consistency for the scales ranged between 0.79- 0.91, and each item was also most strongly correlated with its hypothesised domain than alternative domains. The intra-class test- retest reliability of the UBQ-H scales ranged from 0.65 to 0.81 for patients with stable health. Results supported the construct validity of the UBQ-H. The UBQ-H was significantly correlated with other information on quality of life (for example, General Health Questionnaire) as anticipated. The instrument was able to distinguish between contrasted groups of patients (for example, with versus without symptoms of dyspnoea, prior myocardial infarction versus none, etc), and was responsive to changes in health associated with adverse events requiring hospitalisation. CONCLUSIONS: The modifications made to the Health Measurement Questionnaire has resulted in an assessment designed for cardiovascular patients that has proved to be both reliable and valid.   PMID:10562879

Review of bubble detector response characteristics and results from space.  

PubMed

A passive neutron-bubble dosemeter (BD), developed by Bubble Technology Industries, has been used for space applications. Both the bubble detector-personal neutron dosemeter and bubble detector spectrometer have been studied at ground-based facilities in order to characterise their response due to neutrons, heavy ion particles and protons. This technology was first used during the Canadian-Russian collaboration aboard the Russian satellite BION-9, and subsequently on other space missions, including later BION satellites, the space transportation system, Russian MIR space station and International Space Station. This paper provides an overview of the experiments that have been performed for both ground-based and space studies in an effort to characterise the response of these detectors to various particle types in low earth orbit and presents results from the various space investigations.

Current test results for the Athena radar responsive tag  

NASA Astrophysics Data System (ADS)

Sandia National Laboratories has teamed with General Atomics and Sierra Monolithics to develop the Athena tag for the Army's Radar Tag Engagement (RaTE) program. The radar-responsive Athena tag can be used for Blue Force tracking and Combat Identification (CID) as well as data collection, identification, and geolocation applications. The Athena tag is small (~4.5" x 2.4" x 4.2"), battery-powered, and has an integral antenna. Once remotely activated by a Synthetic Aperture Radar (SAR) or Moving Target Indicator (MTI) radar, the tag transponds modulated pulses to the radar at a low transmit power. The Athena tag can operate Ku-band and X-band airborne SAR and MTI radars. This paper presents results from current tag development testing activities. Topics covered include recent field tests results from the AN/APY-8 Lynx, F16/APG-66, and F15E/APG-63 V(1) radars and other Fire Control radars. Results show that the Athena tag successfully works with multiple radar platforms, in multiple radar modes, and for multiple applications. Radar-responsive tags such as Athena have numerous applications in military and government arenas. Military applications include battlefield situational awareness, combat identification, targeting, personnel recovery, and unattended ground sensors. Government applications exist in nonproliferation, counter-drug, search-and-rescue, and land-mapping activities.

Clinical trial participants’ experiences of completing questionnaires: a qualitative study  

PubMed Central

Objectives To improve clinical study developments for elderly populations, we aim to understand how they transfer their experiences into validated, standardised self-completed study measurement instruments. We analysed how women (mean 78±8?years of age) participating in a randomised controlled trial (RCT) cognised study instruments used to evaluate outcomes of the intervention. Setting The interview study was nested in an RCT on chronic neck pain using common measurement instruments situated in an elderly community in Berlin, Germany, which comprised of units for independent and assisted-living options. Participants The sample (n=20 women) was selected from the RCT sample (n=117, 95% women, mean age 76 (SD±8)?years). Interview participants were selected using a purposive sampling list based on the RCT outcomes. Outcomes We asked participants about their experiences completing the RCT questionnaires. Interviews were analysed thematically, then compared with the questionnaires. Results Interviewees had difficulties in translating complex experiences into a single value on a scale and understanding the relationship of the questionnaires to study aims. Interviewees considered important for the trial that their actual experiences were understood by trial organisers. This information was not transferrable by means of the questionnaires. To rectify these difficulties, interviewees used strategies such as adding notes, adding response categories or skipping an item. Conclusions Elderly interview participants understood the importance of completing questionnaires for trial success. This led to strategies of completing the questionnaires that resulted in ‘missing’ or ambiguous data. To improve data collection in elderly populations, educational materials addressing the differential logics should be developed and tested. Pilot testing validated instruments using cognitive interviews may be particularly important in such populations. Finally, when the target of an intervention is a subjective experience, it seems important to create a method by which participants can convey their personal experiences. These could be nested qualitative studies. Trial registration number ISRCTN77108101807. PMID:24662446

Development of a "Steps Questionnaire".  

PubMed

Thousands of men and women have begun their recovery from alcoholism through the support of Alcoholics Anonymous (AA) and its well-known "12-Step" program. The purpose of the present study was to develop a scale to measure alcoholics' levels of agreement with the first three of AA's 12 Steps and to test the relationship between sobriety and belief in these three steps. Using both factor analysis and Rasch analysis, two versions of a "Steps Questionnaire" were developed. A 96-member subset of the original subject pool was assessed quarterly for 1 year following inpatient treatment to determine the predictive validity of the questionnaire. The results of this study suggested that agreement with AA's first three steps can be measured and that agreement with AA's first step correlates with number of sober days posttreatment. The dichotomization of Steps Questionnaire scores into total agreement versus partial agreement with Step 1, and from this the reduction of uncertainty in the prediction of abstention over a lengthy follow-up period, provides support for AA's contention that total surrender to one's powerlessness over alcohol is part of the process of achieving abstention.

Development and validation of the Newcastle laryngeal hypersensitivity questionnaire  

PubMed Central

Background Laryngeal hypersensitivity may be an important component of the common disorders of laryngeal motor dysfunction including chronic refractory cough, pdoxical vocal fold movement (vocal cord dysfunction), muscle tension dysphonia, and globus pharyngeus. Patients with these conditions frequently report sensory disturbances, and an emerging concept of the ‘irritable larynx’ suggests common features of a sensory neuropathic dysfunction as a part of these disorders. The aim of this study was to develop a Laryngeal Hypersensitivity Questionnaire for patients with laryngeal dysfunction syndromes in order to measure the laryngeal sensory disturbance occurring in these conditions. Methods The 97 participants included 82 patients referred to speech pathology for behavioural management of laryngeal dysfunction and 15 healthy controls. The participants completed a 21 item self administered questionnaire regarding symptoms of abnormal laryngeal sensation. Factor analysis was conducted to examine correlations between items. Discriminant analysis and responsiveness to change were evaluated. Results The final questionnaire comprised 14 items across three domains: obstruction, pain/thermal, and irritation. The questionnaire demonstrated significant discriminant validity with a mean difference between the patients with laryngeal disorders and healthy controls of 5.5. The clinical groups with laryngeal hypersensitivity had similar abnormal scores. Furthermore the Newcastle Laryngeal Hypersensitivity Questionnaire (LHQ) showed improvement following behavioural speech pathology intervention with a mean reduction in LHQ score of 2.3. Conclusion The Newcastle Laryngeal Hypersensitivity Questionnaire is a simple, non-invasive tool to measure laryngeal pesthesia in patients with laryngeal conditions such as chronic cough, pdoxical vocal fold movement (vocal cord dysfunction), muscle tension dysphonia, and globus pharyngeus. It can successfully differentiate patients from healthy controls and measure change following intervention. It is a promising tool for use in clinical research and practice. PMID:24552215

Validation of a Questionnaire to Screen for Shift Work Disorder  

PubMed Central

Study Objective: At least 15% of the full-time work force is shift workers. Working during the overnight hours, early morning start times, and variable or rotating schedules present a challenge to the circadian system, and these shifts are associated with adverse health and safety consequences. Shift work disorder (SWD), a primary (circadian rhythm) sleep disorder indicated by excessive daytime sleepiness and/or insomnia associated with a shiftwork schedule, is under-recognized by primary care physicians. We sought to develop and validate a questionnaire to screen for high risk of SWD in a shift working population. Design: Shift workers completed a 26-item questionnaire and were evaluated by a sleep specialist (physician) who diagnosed them as either positive or negative for SWD. The physician assessment of SWD was guided by a flow chart that operationalized the ICSD-2 criteria for SWD. Setting: 18 sleep clinics in the USA. Patients or Participants: 311 shift workers. Interventions: Not applicable. Measurements and Results: Responses to the items in the questionnaire were entered into a series of discrimination function analyses to determine the diagnostic value of the items and the fewest number of questions with the best predictive value. The function was then cross-validated. A final 4-item questionnaire has 89% positive predictive value and 62% negative predictive value (sensitivity = 0.74; specificity = 0.82). Conclusions: This Shiftwork Disorder Screening Questionnaire may be appropriate for use in primary care settings to aid in the diagnosis of SWD.

Interaction between gas cooking and GSTM1 null genotype in bronchial responsiveness: results from the European Community Respiratory Health Survey  

PubMed Central

Background Increased bronchial responsiveness is characteristic of asthma. Gas cooking, which is a major indoor source of the highly oxidant nitrogen dioxide, has been associated with respiratory symptoms and reduced lung function. However, little is known about the effect of gas cooking on bronchial responsiveness and on how this relationship may be modified by variants in the genes GSTM1, GSTT1 and GSTP1, which influence antioxidant defences. Methods The study was performed in subjects with forced expiratory volume in one second at least 70% of predicted who took part in the multicentre European Community Respiratory Health Survey, had bronchial responsiveness assessed by methacholine challenge and had been genotyped for GSTM1, GSTT1 and GSTP1-rs1695. Information on the use of gas for cooking was obtained from interviewer-led questionnaires. Effect modification by genotype on the association between the use of gas for cooking and bronchial responsiveness was assessed within each participating country, and estimates combined using meta-analysis. Results Overall, gas cooking, as compared with cooking with electricity, was not associated with bronchial responsiveness (?=?0.08, 95% CI ?0.40 to 0.25, p=0.648). However, GSTM1 significantly modified this effect (? for interaction=?0.75, 95% CI ?1.16 to ?0.33, p=4×10?4), with GSTM1 null subjects showing more responsiveness if they cooked with gas. No effect modification by GSTT1 or GSTP1-rs1695 genotypes was observed. Conclusions Increased bronchial responsiveness was associated with gas cooking among subjects with the GSTM1 null genotype. This may reflect the oxidant effects on the bronchi of exposure to nitrogen dioxide. PMID:24613990

COMPARISON OF RESPONSE OF 9977 TEST PACKAGES TO ANALYTICAL RESULTS  

SciTech Connect

Each of the hypothetical accident test cases for the 9977 prototypes was included in the battery of finite element structural analyses performed for the package. Comparison of the experimental and analytical results provides a means of confirming that the analytical model correctly represents the physical behavior of the package. The ability of the analytical model to correctly predict the performance of the foam overpack material for the crush test is of particular interest. The dissipation of energy in the crushing process determines the deceleration of the package upon impact and the duration of the impact. In addition, if the analytical model correctly models the foam behavior, the predicted deformation of the package will match that measured on the test articles. This study compares the deformations of the test packages with the analytical predictions. In addition, the impact acceleration and impact duration for the test articles are compared with those predicted by the analyses.

Incongruent abstract stimulus-response bindings result in response interference: FMRI and EEG evidence from visual object classification priming.  

PubMed

Stimulus repetition often leads to facilitated processing, resulting in neural decreases (repetition suppression) and faster RTs (repetition priming). Such repetition-related effects have been attributed to the facilitation of repeated cognitive processes and/or the retrieval of previously encoded stimulus-response (S-R) bindings. Although previous research has dissociated these two forms of learning, their interaction in the brain is not fully understood. Utilizing the spatial and temporal resolutions of fMRI and EEG, respectively, we examined a long-lag classification priming paradigm that required response repetitions or reversals at multiple levels of response representation. We found a repetition effect in occipital/temporal cortex (fMRI) that was time-locked to stimulus onset (EEG) and robust to switches in response, together with a repetition effect in inferior pFC (fMRI) that was time-locked to response onset (EEG) and sensitive to switches in response. The response-sensitive effect occurred even when changing from object names (words) to object pictures between repetitions, suggesting that S-R bindings can code abstract representations of stimuli. Most importantly, we found evidence for interference effects when incongruent S-R bindings were retrieved, with increased neural activity in inferior pFC, demonstrating that retrieval of S-R bindings can result in facilitation or interference, depending on the congruency of response between repetitions.

Development of the young spine questionnaire  

PubMed Central

Background Back pain in children is common and early onset of back pain has been shown to increase the risk of back pain significantly in adulthood. Consequently, preventive efforts must be targeted the young population but research relating to spinal problems in this age group is scarce. Focus has primarily been on the working age population, and therefore specific questionnaires to measure spinal pain and its consequences, specifically aimed at children and adolescents are absent. The purpose of this study was to develop a questionnaire for schoolchildren filling this gap. Methods The Young Spine Questionnaire (YSQ) was developed in three phases – a conceptualisation, development and testing phase. The conceptualisation phase followed the Wilson and Cleary model and included questions regarding spinal prevalence estimates, pain frequency and intensity, activity restrictions, care seeking behaviour and influence of parental back trouble. Items from existing questionnaires and the “Revised Faces Pain Scale” (rFPS) were included during the development phase. The testing phase consisted of a mixed quantitative and qualitative iterative method carried out in two pilot tests using 4th grade children and focusing on assessment of spinal area location and item validity. Results The testing phase resulted in omission of the pain drawings and the questions and answer categories were simplified in several questions. Agreement between the questionnaire prevalence estimates and the interviews ranged between 83.7% (cervical pain today) and 97.9% (thoracic pain today). To improve the understanding of the spinal boundaries we added bony landmarks to the spinal drawings after pilot test I. This resulted in an improved sense of spinal boundary location in pilot test II. Correlations between the rFPS and the interview pain score ranged between 0.67 (cervical spine) and 0.79 (lumbar spine). Conclusions The Young Spine Questionnaire contains questions that assess spinal pain and its consequences. The items have been tested for content understanding and agreement between questionnaire scores and interview findings among target respondents. These preliminary results suggest that the YSQ is feasible, has content validity and is a well understood questionnaire to be used in studies of children aged 9 to 11 years. PMID:23758965

Psychometric properties evaluation of a new ergonomics-related job factors questionnaire developed for nursing workers.  

PubMed

The objectives of this study were to develop a questionnaire that evaluates the perception of nursing workers to job factors that may contribute to musculoskeletal symptoms, and to evaluate its psychometric properties. Internationally recommended methodology was followed: construction of domains, items and the instrument as a whole, content validity, and pre-test. Psychometric properties were evaluated among 370 nursing workers. Construct validity was analyzed by the factorial analysis, known-groups technique, and convergent validity. Reliability was assessed through internal consistency and stability. Results indicated satisfactory fit indices during confirmatory factor analysis, significant difference (p < 0.01) between the responses of nursing and office workers, and moderate correlations between the new questionnaire and Numeric Pain Scale, SF-36 and WRFQ. Cronbach's alpha was close to 0.90 and ICC values ranged from 0.64 to 0.76. Therefore, results indicated that the new questionnaire had good psychometric properties for use in studies involving nursing workers. PMID:24931478

The MPC&A Questionnaire  

SciTech Connect

The questionnaire is the instrument used for recording performance data on the nuclear material protection, control, and accountability (MPC&A) system at a nuclear facility. The performance information provides a basis for evaluating the effectiveness of the MPC&A system. The goal for the questionnaire is to provide an accurate representation of the performance of the MPC&A system as it currently exists in the facility. Performance grades for all basic MPC&A functions should realistically reflect the actual level of performance at the time the survey is conducted. The questionnaire was developed after testing and benchmarking the material control and accountability (MC&A) system effectiveness tool (MSET) in the United States. The benchmarking exercise at the Idaho National Laboratory (INL) proved extremely valuable for improving the content and quality of the early versions of the questionnaire. Members of the INL benchmark team identified many areas of the questionnaire where questions should be clarified and areas where additional questions should be incorporated. The questionnaire addresses all elements of the MC&A system. Specific parts pertain to the foundation for the facility's overall MPC&A system, and other parts pertain to the specific functions of the operational MPC&A system. The questionnaire includes performance metrics for each of the basic functions or tasks performed in the operational MPC&A system. All of those basic functions or tasks are represented as basic events in the MPC&A fault tree. Performance metrics are to be used during completion of the questionnaire to report what is actually being done in relation to what should be done in the performance of MPC&A functions.

Translation into Portuguese of questionnaires to assess knee injuries.  

PubMed

The aim of this systematic review was to review the quality of the translation and the measurement properties from questionnaires that assess injuries of the knee. We included questionnaires that were developed in foreign language and have been translated and validated into Portuguese. The databases used were CINAHL, SPORTDiscus, LILACS, PUBMED and SCIELO and the final search resulted in a total of 868 studies included, from which 16 were eligible. Most included questionnaires presented all steps expected in a translation process; however there were some deficiencies in measurement properties among the questionnaires. The VISA-P Brazil was the best questionnaire when analyzing translation process and measurement properties tested. It was the only questionnaire that tested all measurement properties investigated and presented adequate values for all of them. KOS-ADLS was the best questionnaire translated to Portuguese from Portugal. Among all, the VISA-P Brazil is the best questionnaire to be used with Brazilian Portuguese speakers when the condition is related to patellar tendinopathy and the LEFS is the best questionnaire for other general conditions of the knee. For Portuguese from Portugal, the best questionnaire is the KOS-ADLS, and like the LEFS it does not target any specific injury. PMID:24453685

NCI developed a new instrument called the NHANES Food Frequency Questionnaire (formerly called Food Propensity Questionnaire) and supported its application in the National Health and Nutrition Examination Survey (NHANES). This instrument collects much of the same information as a food frequency questionnaire (FFQ), but without asking about portion size. The resulting data can be employed in the NCI usual dietary intakes model as covariates. By not asking about portion size, the NHANES FFQ requires less respondent burden than other FFQs.

An empirical comparison of the St George's Respiratory Questionnaire (SGRQ) and the Chronic Respiratory Disease Questionnaire (CRQ) in a clinical trial setting  

PubMed Central

BACKGROUND—The Chronic Respiratory Questionnaire (CRQ) and the St George's Respiratory Questionnaire (SGRQ) are the two most widely used quality of life questionnaires in chronic obstructive pulmonary disease (COPD). A study was undertaken to compare directly the self-administered version of the CRQ and the SGRQ with respect to feasibility, internal consistency, validity, and sensitivity to changes resulting from bronchodilator therapy.?METHODS—One hundred and forty four patients with moderate or severe COPD were randomly assigned to receive three months of treatment with either salmeterol, salmeterol + ipratropium bromide, or placebo. Quality of life was measured at baseline and after 12 weeks of treatment.?RESULTS—The proportions of missing values per patient were low for both questionnaires (0.54% for the CRQ and 2% for the SGRQ). The internal consistency was good for both questionnaires (Cronbach's ? coefficients ?0.84 for the CRQ and ?0.76 for the SGRQ). Factor analysis confirmed the original domain structure of the CRQ but not of the SGRQ. Correlations with forced expiratory volume in one second (FEV1) % predicted and peak expiratory flow rate (PEFR) were low for both questionnaires but better for the SGRQ than for the CRQ. The ability to discriminate between subjects with different levels of FEV1 was somewhat better for the SGRQ. The correlations with symptom scores were comparable for both questionnaires. Cross sectionally, the scores of the two questionnaires were moderately to highly correlated (coefficients ranged from 0.35 to 0.72). Longitudinally, these correlations were lower (coefficients ranged from 0.17 to 0.54) but were still significant. The CRQ total and emotions score and the SGRQ symptoms score were the most responsive to change. The SGRQ symptoms domain was the only domain where the improvement in patients receiving combination treatment crossed the threshold for clinical relevance.?CONCLUSIONS—Since this analysis of reliability, validity, and responsiveness to change did not clearly favour one instrument above the other, the choice between the CRQ and the SGRQ can be based on other considerations such as the required sample size or the availability of reference values.??

Tablet, Web-Based, or Paper Questionnaires for Measuring Anxiety in Patients Suspected of Breast Cancer: Patients' Preferences and Quality of Collected Data  

PubMed Central

Background Electronic applications are increasingly being used in hospitals for numerous purposes. Objective Our aim was to assess differences in the characteristics of patients who choose paper versus electronic questionnaires and to evaluate the data quality of both approaches. Methods Between October 2012 and June 2013, 136 patients participated in a study on diagnosis-induced stress and anxiety. Patients were asked to fill out questionnaires at six different moments during the diagnostic phase. They were given the opportunity to fill out the questionnaires on paper or electronically (a combination of tablet and Web-based questionnaires). Demographic characteristics and completeness of returned data were compared between groups. Results Nearly two-thirds of patients (88/136, 64.7%) chose to fill out the questionnaires on paper, and just over a third (48/136, 35.3%) preferred the electronic option. Patients choosing electronic questionnaires were significantly younger (mean 47.3 years vs mean 53.5 in the paper group, P=.01) and higher educated (P=.004). There was significantly more missing information (ie, at least one question not answered) in the paper group during the diagnostic day compared to the electronic group (using a tablet) (28/88 vs 1/48, P<.001). However, in the week after the diagnostic day, missing information was significantly higher in the electronic group (Web-based questionnaires) compared to the paper group (41/48 vs 38/88, P<.001). Conclusions Younger patients and patients with a higher level of education have a preference towards filling out questionnaires electronically. In the hospital, a tablet is an excellent medium for patients to fill out questionnaires with very little missing information. However, for filling out questionnaires at home, paper questionnaires resulted in a better response than Web-based questionnaires. PMID:25364951

Smallpox Still Haunts Scientists: Results of a Questionnaire-Based Inquiry on the Views of Health Care and Life Science Experts and Students on Preserving the Remaining Variola Virus Stocks  

PubMed Central

The World Health Organization (WHO) declared eradication of the dreadful disease “smallpox” in 1980. Though the disease has died down, the causative virus “variola” has not, as it has been well preserved in two high security laboratories—one in USA and another in Russia. The debate on whether the remaining stocks of the smallpox virus should be destroyed or not is ongoing, and the World Health Assembly (WHA) in 2011 has decided to postpone the review on this debate to the 67th WHA in 2014. A short questionnaire-based inquiry was organized during a one-day stem cell meeting to explore the views of various health care and life science specialists especially students on this aspect. Among the 200 participants of the meeting, only 66 had answered the questionnaire. 60.6% of participants who responded to the questionnaire were for preserving the virus for future reference, while 36.4% of the participants were for destroying the virus considering the magnitude with which it killed millions. However, 3% of the respondents were not able to decide on any verdict. Therefore, this inquiry expresses the view that “what we cannot create, we do not have the right to destroy.” PMID:23970838

Sexual behavioral abstine HIV/AIDS questionnaire: Validation study of an Iranian questionnaire  

PubMed Central

Background: This study was designed to assess the validity and reliability of the designed sexual, behavioral abstinence, and avoidance of high-risk situation questionnaire (SBAHAQ), with an aim to construct an appropriate development tool in the Iranian population. Materials and Methods: A descriptive–analytic study was conducted among female undergraduate students of Tehran University, who were selected through cluster random sampling. After reviewing the questionnaires and investigating face and content validity, internal consistency of the questionnaire was assessed by Cronbach's alpha. Explanatory and confirmatory factor analysis was conducted using SPSS and AMOS 16 Software, respectively. Results: The sample consisted of 348 female university students with a mean age of 20.69 ± 1.63 years. The content validity ratio (CVR) coefficient was 0.85 and the reliability of each section of the questionnaire was as follows: Perceived benefit (PB; 0.87), behavioral intention (BI; 0.77), and self-efficacy (SE; 0.85) (Cronbach's alpha totally was 0.83). Explanatory factor analysis showed three factors, including SE, PB, and BI, with the total variance of 61% and Kaiser–Meyer–Olkin (KMO) index of 88%. These factors were also confirmed by confirmatory factor analysis [adjusted goodness of fitness index (AGFI) = 0.939, root mean square error of approximation (RMSEA) = 0.039]. Conclusion: This study showed the designed questionnaire provided adequate construct validity and reliability, and could be adequately used to measure sexual abstinence and avoidance of high-risk situations among female students.

Measurement Properties of a Park Use Questionnaire  

PubMed Central

We determined the criterion validity and test-retest reliability of a brief park use questionnaire. From five US locations, 232 adults completed a brief survey four times and wore a global positioning system (GPS) monitor for three weeks. We assessed validity for park visits during the past week and during a usual week by examining agreement between frequency and duration of park visits reported in the questionnaire to the GPS monitor results. Spearman correlation coefficients (SCC) were used to measure agreement. For past week park visit frequency and duration, the SCC were 0.62–0.65 and 0.62–0.67, respectively. For usual week park visit frequency and duration, the SCC were 0.40–0.50 and 0.50–0.53, respectively. Usual park visit frequency reliability was 0.78–0.88 (percent agreement 69%–82%) and usual park visit duration was 0.75–0.84 (percent agreement 64%–73%). These results suggest that the questionnaire to assess usual and past week park use had acceptable validity and reliability. PMID:23853386

Electroporation mediated DNA vaccination directly to a mucosal surface results in improved immune responses.  

PubMed

In vivo electroporation (EP) has been shown to be a highly efficient non-viral method for enhancing DNA vaccine delivery and immunogenicity, when the site of immunization is the skin or muscle of animals and humans. However, the route of entry for many microbial pathogens is via the mucosal surfaces of the human body. We have previously reported on minimally invasive, surface and contactless EP devices for enhanced DNA delivery to dermal tissue. Robust antibody responses were induced following vaccine delivery in several tested animal models using these devices. Here, we investigated extending the modality of the surface device to efficiently deliver DNA vaccines to mucosal tissue. Initially, we demonstrated reporter gene expression in the epithelial layer of buccal mucosa in a guinea pig model. There was minimal tissue damage in guinea pig mucosal tissue resulting from EP. Delivery of a DNA vaccine encoding influenza virus nucleoprotein (NP) of influenza H1N1 elicited robust and sustained systemic IgG antibody responses following EP-enhanced delivery in the mucosa. Upon further analysis, IgA antibody responses were detected in vaginal washes and sustained cellular immune responses were detected in animals immunized at the oral mucosa with the surface EP device. This data confirms that DNA delivery and EP targeting mucosal tissue directly results in both robust and sustainable humoral as well as cellular immune responses without tissue damage. These responses are seen both in the mucosa and systemically in the blood. Direct DNA vaccine delivery enhanced by EP in mucosa may have important clinical applications for delivery of prophylactic and therapeutic DNA vaccines against diseases such as HIV, HPV and pneumonia that enter at mucosal sites and require both cellular and humoral immune responses for protection.

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  

PubMed Central

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 psychological variables. Among the longer disease-specific questionnaires, only the AQLQ emerged as predictor of ED visits in asthma patients (OR: 0.9; p?=?.002; AUC 0.727). In the second year of follow-up, none of HRQoL questionnaires predicted exacerbations. Conclusions AQ20 predicts exacerbations in asthma and CCQ predicts ED visits in COPD in the first year of follow-up. Their predictive ability is similar to or even higher than that of longer disease-specific questionnaires. PMID:23706146

The development of a questionnaire to describe science teacher communication behavior in Taiwan and Australia  

NASA Astrophysics Data System (ADS)

Teachers contribute enormously to a positive social climate in science classes, particularly through their communication with students. This article describes the development and validation of a questionnaire, the Teacher Communication Behavior Questionnaire (TCBQ) (see pp. 723-726), which assesses student perceptions of the following five important teacher behaviors: Challenging, Encouragement and Praise, Non-Verbal Support, Understanding and Friendly, and Controlling. The TCBQ was administered to 1202 students from 30 classes in Taiwan and to 301 students from 12 classes in Australia. The reliability and factorial validity of the TCBQ were found to be satisfactory for both the Taiwanese and Australian data. To further validate the questionnaire and understand the differences in teacher behavior according to the perceptions of students from the two countries, a qualitative approach was used. Students were interviewed (two from each of five classes) in both Taiwan and Australia. The interview questions focused on these students' responses to selected questionnaire items. The results obtained from the interviews supported and helped explain the quantitative results. In an application of the TCBQ in both countries, students' perceptions on four of the scales of the TCBQ were associated with their attitudes to their science classes.

Good agreement between questionnaire and administrative databases for health care use and costs in patients with osteoarthritis  

PubMed Central

Background Estimating costs is essential to the economic analysis of health care programs. Health care costs are often captured from administrative databases or by patient report. Administrative records only provide a partial representation of health care costs and have additional limitations. Patient-completed questionnaires may allow a broader representation of health care costs; however the validity and feasibility of such methods have not been firmly established. This study was conducted to assess the validity and feasibility of using a patient-completed questionnaire to capture health care use and costs for patients with osteoarthritis, and to compare the research costs of the data-capture methods. Methods We designed a patient questionnaire and applied it in a clinical trial. We captured equivalent data from four administrative databases. We evaluated aspects of the questionnaire's validity using sensitivity and specificity, Lin's concordance correlation coefficient (?c), and Bland-Altman comparisons. Results The questionnaire's response rate was 89%. Acceptable sensitivity and specificity levels were found for all types of health care use. The numbers of visits and the majority of medications reported by patients were in agreement with the database-derived estimates (?c > 0.40). Total cost estimates from the questionnaire agreed with those from the databases. Patient-reported co-payments agreed with administrative records with respect to GP office transactions, but not pharmaceutical co-payments. Research costs for the questionnaire-based method were less than one-third of the costs for the databases method. Conclusion A patient-completed questionnaire is feasible for capturing health care use and costs for patients with osteoarthritis, and data collected using it mostly agree with administrative databases. Caution should be exercised when applying unit costs and collecting co-payment data. PMID:21489280

Polish adaptation of Bad Sobernheim Stress Questionnaire-Brace and Bad Sobernheim Stress Questionnaire-Deformity.  

PubMed

Bad Sobernheim Stress Questionnaire-Brace and Bad Sobernheim Stress Questionnaire-Deformity are relatively new tools aimed at facilitating the evaluation of long-term results of therapy in persons with idiopathic scoliosis undergoing conservative treatment. To use these tools properly in Poland, they must be translated into Polish and adapted to the Polish cultural settings. The process of cultural adaptation of the questionnaires was compliant with the guidelines of International Quality of Life Assessment (IQOLA) Project. In the first stage, two independent translators converted the originals into Polish. Stage two, consisted of a comparison of the originals and two translated versions. During that stage, the team of two translators and authors of the project identified differences in those translations and created a combination of the two. In the third stage, two independent translators, who were native speakers of German, translated the adjusted version of the Polish translation into the language of the original document. At the last stage, a commission composed of: specialists in orthopedics, translators, a statistician and a psychologist reviewed all translations and drafted a pre-final version of the questionnaires. Thirty-five adolescent girls with idiopathic scoliosis who were treated with Cheneau brace were subjected to the questionnaire assessment. All patients were treated in an out-patient setting by a specialist in orthopedics at the Chair and Clinic of Orthopedics and Traumatology. Median age of patients was 14.8 SD 1.5, median value of the Cobb's angle was 27.8 degrees SD 7.4. 48.6% of patients had thoracic scoliosis, 31.4% had thoracolumbar scoliosis, and 20% patients had lumbar scoliosis. Median results obtained by means of the Polish version of BSSQ-Brace and BSSQ-Deformity questionnaires were 17.9 SD 5.0 and 11.3 SD 4.7, respectively. Internal consistency of BSSQ-Brace and BSSQ-Deformity was at the level of 0.80 and 0.87, whereas the value of the absolute stability factor was 0.82 and 0.88. Overall, the Polish versions of the BSSQ-Brace and BSSQ-Deformity Questionnaires are characterized by high values of internal consistency factor and absolute stability factor. Following the process of adaptation, the authors obtained a tool that is instrumental in clinical evaluations and complies with methodological criteria. PMID:19669802

‘How Poor Are You?’ – A Comparison of Four Questionnaire Delivery Modes for Assessing Socio-Economic Position in Rural Zimbabwe  

PubMed Central

Background Assessing socio-economic position can be difficult, particularly in developing countries. Collection of socio-economic data usually relies on interviewer-administered questionnaires, but there is little research exploring how questionnaire delivery mode (QDM) influences reporting of these indicators. This paper reports on results of a trial of four QDMs, and the effect of mode on poverty reporting. Methods This trial was nested within a community-randomised trial of an adolescent reproductive health intervention conducted in rural Zimbabwe. Participants were randomly allocated to one of four QDMs (three different self-administered modes and one interviewer-administered mode); a subset was randomly selected to complete the questionnaire twice. Questions covered three socio-economic domains: i) ownership of sellable and fixed assets; ii) ability to afford essential items; and iii) food sufficiency. Statistical analyses assessed the association between QDM and reporting of poverty, and compared the extent of response agreement between questionnaire rounds. Results 96% (n?=?1483) of those eligible took part; 395 completed the questionnaire twice. Reported levels of poverty were high. Respondents using self-administered modes were more likely to report being unable to afford essential items and having insufficient food. Among those completing the questionnaire twice using different modes, higher levels of poverty and food insufficiency were reported when they completed the questionnaire using a self-administered mode. Conclusion These data suggest that QDM plays a significant role in how different socio-economic indicators are reported, and reminds us to consider the mode of collection when identifying indicators to determine socio-economic position.

Postnatal episodic ozone results in persistent attenuation of pulmonary and peripheral blood responses to LPS challenge  

PubMed Central

Early life is a dynamic period of growth for the lung and immune system. We hypothesized that ambient ozone exposure during postnatal development can affect the innate immune response to other environmental challenges in a persistent fashion. To test this hypothesis, we exposed infant rhesus macaque monkeys to a regimen of 11 ozone cycles between 30 days and 6 mo of age; each cycle consisted of ozone for 5 days (0.5 parts per million at 8 h/day) followed by 9 days of filtered air. Animals were subsequently housed in filtered air conditions and challenged with a single dose of inhaled LPS at 1 yr of age. After completion of the ozone exposure regimen at 6 mo of age, total peripheral blood leukocyte and polymorphonuclear leukocyte (PMN) numbers were reduced, whereas eosinophil counts increased. In lavage, total cell numbers at 6 mo were not affected by ozone, however, there was a significant reduction in lymphocytes and increased eosinophils. Following an additional 6 mo of filtered air housing, only monocytes were increased in blood and lavage in previously exposed animals. In response to LPS challenge, animals with a prior history of ozone showed an attenuated peripheral blood and lavage PMN response compared with controls. In vitro stimulation of peripheral blood mononuclear cells with LPS resulted in reduced secretion of IL-6 and IL-8 protein in association with prior ozone exposure. Collectively, our findings suggest that ozone exposure during infancy can result in a persistent effect on both pulmonary and systemic innate immune responses later in life. PMID:21131396

The Comparative Validity of Interactive Multimedia Questionnaires to Paper-Administered Questionnaires for Beverage Intake and Physical Activity: Pilot Study  

PubMed Central

Background Brief, valid, and reliable dietary and physical activity assessment tools are needed, and interactive computerized assessments (ie, those with visual cues, pictures, sounds, and voiceovers) can reduce administration and scoring burdens commonly encountered with paper-based assessments. Objective The purpose of this pilot investigation was to evaluate the comparative validity and reliability of interactive multimedia (IMM) versions (ie, IMM-1 and IMM-2) compared to validated paper-administered (PP) versions of the beverage intake questionnaire (BEVQ-15) and Stanford Leisure-Time Activity Categorical Item (L-Cat); a secondary purpose was to evaluate results across two education attainment levels. Methods Adults 21 years or older (n=60) were recruited to complete three laboratory sessions, separated by three to seven days in a randomly assigned sequence, with the following assessments–demographic information, two IMM and one paper-based (PP) version of the BEVQ-15 and L-Cat, health literacy, and an IMM usability survey. Results Responses across beverage categories from the IMM-1 and PP versions (validity; r=.34-.98) and the IMM-1 and IMM-2 administrations (reliability; r=.61-.94) (all P<.001) were significantly correlated. Paired t tests revealed significant differences in sugar-sweetened beverage (SSB) grams and kcal (P=.02 and P=.01, respectively) and total beverage kcal (P=.03), on IMM-1 and IMM-2; however, comparative validity was demonstrated between IMM-2 and the PP version suggesting familiarization with the IMM tool may influence participant responses (mean differences: SSB 63 grams, SEM 87; P=.52; SSB 21 kcal, SEM 33; P=.48; total beverage 65 kcal, SEM 49; P=.19). Overall mean scores between the PP and both IMM versions of the L-Cat were different (both P<.001); however, responses on all versions were correlated (P<.001). Differences between education categories were noted at each L-Cat administration (IMM-1: P=.008; IMM-2: P=.001; PP: P=.002). Major and minor themes from user feedback suggest that the IMM questionnaires were easy to complete, and relevant to participants' typical beverage choices and physical activity habits. Conclusions In general, less educated participants consumed more total beverage and SSB energy, and reported less engagement in physical activity. The IMM BEVQ-15 appears to be a valid and reliable measure to assess habitual beverage intake, although software familiarization may increase response accuracy. The IMM-L-Cat can be considered reliable and may have permitted respondents to more freely disclose actual physical activity levels versus the paper-administered tool. Future larger-scale investigations are warranted to confirm these possibilities. PMID:24148226

Behavioural, emotional, and cognitive responses in European disasters: results of survivor interviews.  

PubMed

In the European multi-centre study BeSeCu (Behaviour, Security, Culture), interviews were conducted in seven countries to explore survivors' emotional, behavioural, and cognitive responses during disasters. Interviews, either in groups or one-to-one, were convened according to type of event: collapse of a building; earthquake; fire; flood; and terror attack. The content analysis of interviews resulted in a theoretical framework, describing the course of the events, behavioural responses, and the emotional and cognitive processing of survivors. While the environmental cues and the ability to recognise what was happening varied in different disasters, survivors' responses tended to be more universal across events, and most often were adaptive and non-selfish. Several peri-traumatic factors related to current levels of post-traumatic stress were identified, while memory quantity did not differ as a function of event type or post-traumatic stress. Time since the event had a minor effect on recall. Based on the findings, several suggestions for emergency training are made. PMID:24325239

Non-local spatial frequency response of photopolymer materials containing chain transfer agents: II. Experimental results  

NASA Astrophysics Data System (ADS)

In part I of this paper the non-local photo-polymerization driven diffusion model was extended to include the kinetics of chain transfer and re-initiation, in order to analyse the effects of chain transfer agents on the system kinetics and to study their use in reducing the average polymer chain length in free-radical based photopolymer materials. Based on these results, it is proposed that one possible way to improve the material response at high spatial frequency is the addition of chain transfer agents. In this paper, the validity of the proposed model is examined by applying it to fit experimental data for an acrylamide/polyvinyl alcohol (AA/PVA) layer containing two different types of chain transfer agent (CTA): sodium formate (HCOONa) and 1-mercapto-2-propanol (CH3CH(OH)CH2SH). The effects on decreasing the average polymer chain length formed, by the addition of chain transfer agent, which in turn reduces the non-local response of the material, are demonstrated. These reductions are shown to be accompanied by improved high spatial frequency response. Key material parameters are extracted by numerically fitting experimentally measured refractive index modulation growth curves using the model. Further independent experimental confirmation of the reduction in the average polymer molecular weight is provided using a diffusion based holographic technique.

Neurobehavioural test results and exposure to inorganic mercury: in search of dose-response relations.  

PubMed

The aim of the analysis was, in general, to find a way to summarise results of studies in search of exposure-response relationships and, in particular, to ask whether an exposure-response relationship can be ascertained for neurobehavioural studies on occupational mercury exposure. Eighteen studies dealing with human mercury exposure and examining 1,106 exposed and 1,105 control subjects were included in the analysis. Effect sizes were calculated for each of the single neuropsychological test results on cognitive and motor performance and were considered in relation to mean current concentrations of exposure. The total of effect sizes demonstrated a correlation to exposure in the range of r=0.50. Additional analyses showed that the influence of mercury on psychological functions was different and that results on motor performance compared with memory and attention revealed the greatest impairment in mercury-exposed workers. Implications for the reversibility of impairments could be discussed because three of the studies examined subjects whose exposure had ceased. Besides the usefulness of the approach, it became obvious that the available 18 studies are a small sample, even when non-dimensional effect-sizes are used; hence, not all psychological domains covered by tests could be analysed.

Systematic development and validation of a theory-based questionnaire to assess toddler feeding.  

PubMed

This paper describes the development and validation of a 27-item caregiver-reported questionnaire on toddler feeding. The development of the Toddler Feeding Behavior Questionnaire was based on a theory of interactive feeding that incorporates caregivers' responses to concerns about their children's dietary intake, appetite, size, and behaviors rather than relying exclusively on caregiver actions. Content validity included review by an expert panel (n = 7) and testing in a pilot sample (n = 105) of low-income mothers of toddlers. Construct validity and reliability were assessed among a second sample of low-income mothers of predominately African-American (70%) toddlers aged 12-32 mo (n = 297) participating in the baseline evaluation of a toddler overweight prevention study. Internal consistency (Cronbach's ?: 0.64-0.87) and test-retest (0.57-0.88) reliability were acceptable for most constructs. Exploratory and confirmatory factor analyses revealed 5 theoretically derived constructs of feeding: responsive, forceful/pressuring, restrictive, indulgent, and uninvolved (root mean square error of approximation = 0.047, comparative fit index = 0.90, standardized root mean square residual = 0.06). Statistically significant (P < 0.05) convergent validity results further validated the scale, confirming established relations between feeding behaviors, toddler overweight status, perceived toddler fussiness, and maternal mental health. The Toddler Feeding Behavior Questionnaire adds to the field by providing a brief instrument that can be administered in 5 min to examine how caregiver-reported feeding behaviors relate to toddler health and behavior.

Worldwide patterns of bronchodilator responsiveness: results from the Burden of Obstructive Lung Disease study  

PubMed Central

Rationale Criteria for a clinically significant bronchodilator response (BDR) are mainly based on studies in patients with obstructive lung diseases. Little is known about the BDR in healthy general populations, and even less about the worldwide patterns. Methods 10?360 adults aged 40?years and older from 14 countries in North America, Europe, Africa and Asia participated in the Burden of Obstructive Lung Disease study. Spirometry was used before and after an inhaled bronchodilator to determine the distribution of the BDR in population-based samples of healthy non-smokers and individuals with airflow obstruction. Results In 3922 healthy never smokers, the weighted pooled estimate of the 95th percentiles (95% CI) for bronchodilator response were 284?ml (263 to 305) absolute change in forced expiratory volume in 1 s from baseline (?FEV1); 12.0% (11.2% to 12.8%) change relative to initial value (%?FEV1i); and 10.0% (9.5% to 10.5%) change relative to predicted value (%?FEV1p). The corresponding mean changes in forced vital capacity (FVC) were 322?ml (271 to 373) absolute change from baseline (?FVC); 10.5% (8.9% to 12.0%) change relative to initial value (?FVCi); and 9.2% (7.9% to 10.5%) change relative to predicted value (?FVCp). The proportion who exceeded the above threshold values in the subgroup with spirometrically defined Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage 2 and higher (FEV1/FVC <0.7 and FEV1% predicted <80%) were 11.1%, 30.8% and 12.9% respectively for the FEV1-based thresholds and 22.6%, 28.6% and 22.1% respectively for the FVC-based thresholds. Conclusions The results provide reference values for bronchodilator responses worldwide that confirm guideline estimates for a clinically significant level of BDR in bronchodilator testing.

Validity and reliability of activities coaching context questionnaire  

PubMed Central

Background: Learning in a clinical environment is an inseparable part of a training program in medical education. To evaluate the quality of training in a clinical environment, a comprehensive questionnaire which is adjusted for local purposes is essential. This study was conducted to determine the validity and reliability of Activities Coaching Context (ACC)-questionnaire from the perspective of residents and students in a clinical learning environment. Methods: This was a cross-sectional study conducted with 65 residents and students of Semnan University of Medical Sciences. The Content Validity of the questionnaire was confirmed by the judgment of a panel of ten experts in medical education. The construct validity of the questionnaire was determined by factor analysis. Data were collected and analyzed by SPSS16. Results: The ratio and index of content validity calculated by experts’ view were quite acceptable (0.31 and 0.7, respectively). Construct validity was examined by factor analysis which confirmed seven first order factors. Cronbach’s Alfa coefficient revealed a high degree of internal consistency (0.932). The reliability of the questionnaire was measured by test - retest (0.9). Conclusions: The ACC questionnaire appeared to be a valid, reliable and also appropriate tool to evaluate the educational quality of a clinical learning environment. PMID:25405107

Factorial invariance of the Patient Health Questionnaire and Generalized Anxiety Disorder Questionnaire  

PubMed Central

Objectives The UK's Improving Access to Psychological Therapies (IAPT) programme uses the Patient Health Questionnaire Depression Scale (PHQ-9; Kroenke, Spitzer, & Williams, 2001, J. Gen. Intern. Med., 16, 606) and Generalized Anxiety Disorder Scale (GAD-7; Spitzer et al., 2006, Arch. Intern. Med., 166, 1092) to assess patients' symptoms of depression and anxiety respectively. Data are typically collected via telephone or face-to-face; however, no study has statistically investigated whether the questionnaires' items operate equivalently across these modes of data collection. This study aimed to address this omission. Methods & Results Questionnaire data from patients registered with an IAPT service in London (N = 23,672) were examined. Confirmatory factor analyses suggested that unidimensional factor structures adequately matched observed face-to-face and telephone data for the PHQ-9 and GAD-7. Invariance analyses revealed that while the PHQ-9 had equivalent factor loadings and latent means across data collection methods, the GAD-7 had equivalent factor loadings but unequal latent means. In support of the scales' convergent validity, positive associations between scores on the PHQ-9 and GAD-7 emerged. Conclusions With the exception of the GAD-7's latent means, the questionnaires' factor loadings and latent means were equivalent. This suggests that clinicians may meaningfully compare PHQ-9 data collected face-to-face and by telephone; however, such comparisons with the GAD-7 should be done with caution. Practitioner points The PHQ-9 and GAD-7's factor loadings were equivalent across data collection methods. Only the PHQ-9's latent means were equivalent across data collection methods. Clinicians may be confident collecting PHQ-9 data by telephone and face-to-face and, then, comparing such data. Caution is recommended when determining clinical effectiveness using telephone and face-to-face GAD-7 data. More psychometric research is warranted. PMID:24117915

Reliability and validity of Leicester Cough Questionnaire Korean version.  

PubMed

The Leicester Cough Questionnaire (LCQ) is a self-administered questionnaire developed in England and validated for reliability. We developed a Korean translation of this questionnaire by applying a sequential forward and backward translation approach. The purpose of this study is to validate the Korean version of the LCQ (LCQ-K) in Korean patients with chronic cough. A multicenter prospective study was undertaken with 100 chronic cough patients who consented to participate in the study. The LCQ-K includes eight physical items, seven psychological items, and four social items. Visual analog scale (VAS) of cough, Borg Cough Scale (BCS), and Short Form-36 (SF-36) were used as external comparators. Participants included 52 women and 48 men with ages ranging from 18 years to 69 years. The concurrent validity comparing LCQ-K to VAS, BCS, and SF-36 yielded statistically significant Pearson correlation coefficients. The LCQ-K showed good reliability in three domains, with Cronbach's ? coefficients ranging from 0.84 to 0.87 (total: 0.91). Test-retest reliability was investigated with single measure intraclass correlation coefficients, which were found to be practically and statistically significant (p = 0.005). Responsiveness was validated by effective size ranging from 1.16 to 1.40 in each domain. LCQ-K is a reliable, valid, and responsive disease-specific questionnaire for assessing symptoms and quality of life of Korean patients with chronic cough. PMID:24906688

Evaluation of a gastrointestinal symptoms questionnaire.  

PubMed

Questionnaires are widely used instruments to monitor gastrointestinal (GI) symptoms. However, few of these questionnaires have been formally evaluated. We sought to evaluate our GI symptoms questionnaire in terms of clarity and reproducibility. Primary care patients referred for open access Helicobacter pylori urea breath testing reported GI symptoms (type+severity) and demographic information by written questionnaire. In an interview, patients gave a personal description of the meaning of the GI symptoms on the questionnaire. Patients' descriptions of GI symptoms were compared with current definitions. Symptom severity scores were compared before and after, interview versus questionnaire. Of the 45 patients included, 19 (42%) described all symptoms correctly, whereas 17 (38%) described one symptom incorrectly. None of the patients made more than three mistakes. Regurgitation was the most common incorrectly described symptom (16 patients [36%]), whereas the other individual symptoms were well explained. Symptom severities before the interview, after the interview and reported by questionnaire (mean value+/-SEM) were 2.1 +/- 0.2, 2.1 +/- 0.2, and 1.5 +/- 0.2 points on a 7-point Likert scale (0-6), respectively. Mean severity reported by interview (95% CI) was 1.4 (1.3-1.5) times higher than reported by questionnaire (P < .05). In conclusion, the GI symptom questionnaire is understandable and has good reproducibility for measuring the presence of GI symptoms, although symptom severity is consistently rated higher when reported by interview.

Validation of the Turkish version of the quality of recovery-40 questionnaire  

PubMed Central

Background The Quality of Recovery-40 questionnaire (QoR-40) is a self-rated questionnaire used to assess the postoperative recovery quality and health status of patients in the early stages following surgery; however, there is no Turkish version of the QoR-40. The aim of this study was to assess the reliability, validity, and responsiveness of the Turkish version of the QoR-40 (QoR-40 T). Methods After the approval of the ethics committee, a total of 137 patients completed the questionnaire during the preoperative period, on the third day, and one month after surgery. The quality of life was evaluated by using a health-related quality of life questionnaire (Short-Form Health Survey-36; SF-36) on the third day and one month after surgery. Reliability, feasibility, and validity were assessed to validate the QoR-40 T. Results The Cronbach’s alpha of the global QoR-40 T on the third day after surgery was 0.936. A positive moderate correlation was obtained between the physical comfort, emotional state, physical independence, and pain dimensions of the QoR-40 T and the physical component summary, mental health, physical functioning, and bodily pain subscales of the SF-36 on the third day after surgery, respectively (physical comfort - physical component summary, ??=?0.292, p?=?0.001; emotional state - mental health, ??=?0.252, p?=?0.003; physical independence - physical functioning, ??=?0.340, p?responsive mean of the total QoR-40 T was 0.62. Conclusions The QoR-40 T showed satisfactory reliability and validity in evaluating the quality of recovery after surgery in the Turkish population. PMID:24428925

Cognitive interviews guide design of a new CAM patient expectations questionnaire  

PubMed Central

Background No consistent relationship exists between pre-treatment expectations and therapeutic benefit from various complementary and alternative medicine (CAM) therapies in clinical trials. However, many different expectancy measures have been used in those studies, with no validated questionnaires clearly focused on CAM and pain. We undertook cognitive interviews as part of a process to develop and validate such a questionnaire. Methods We reviewed questions about expectations of benefits of acupuncture, chiropractic, massage, or yoga for pain. Components of the questions – verbs, nouns, response options, terms and phrases describing back pain – were identified. Using seven different cognitive interview scripts, we conducted 39 interviews to evaluate how individuals with chronic low back pain understood these individual components in the context of expectancy questions for a therapy they had not yet received. Chosen items were those with the greatest agreement and least confusion among participants, and were closest to the meanings intended by the investigators. Results The questionnaire drafted for psychometric evaluation had 18 items covering various domains of expectancy. “Back pain” was the most consistently interpreted descriptor for this condition. The most understandable response options were 0-10 scales, a structure used throughout the questionnaire, with 0 always indicating no change, and 10 anchored with an absolute descriptor such as “complete relief”. The use of words to describe midpoints was found to be confusing. The word “expect” held different and shifting meanings for participants. Thus paired items comparing “hope” and “realistically expect” were chosen to evaluate 5 different aspects of treatment expectations (back pain; back dysfunction and global effects; impact of back pain on specific areas of life; sleep, mood, and energy; coping). “Impact of back pain” on various areas of life was found to be a consistently meaningful concept, and more global than “interference”. Conclusions Cognitive interviews identified wordings with considerable agreement among both participants and investigators. Some items widely used in clinical studies had different meanings to participants than investigators, or were confusing to participants. The final 18-item questionnaire is undergoing psychometric evaluation with goals of streamlining as well as identifying best items for use when questionnaire length is constrained. PMID:24460709

The ARSQ: the athletes' received support questionnaire.  

PubMed

To address calls for context-specific measurement of social support, this article reports the development of the Athletes' Received Support Questionnaire (ARSQ) and demonstrates initial evidence for its validity. Across four studies there was support for a four-dimensional structure reflecting emotional, esteem, informational, and tangible received support. There was also support for unidimensional and higher-order models. Further, Study 3 provided some support for convergent validity, with significant correlations between the corresponding dimensions of the ARSQ and the Inventory of Socially Supportive Behaviors. Study 4 provided evidence for the nomological validity of the ARSQ. Emotional and esteem support significantly predicted self-confidence and positive affect, and tangible support significantly moderated the relationship between stress and negative affect. Collectively, these results provide initial evidence for the validity of the ARSQ, and offer researchers flexibility to adopt either a multidimensional or aggregated approach to measuring received support.

In an effort to extend the validity of the Fear Questionnaire (FQ) in a sample of patients with high levels of blood/injury phobia, the FQ responses of 255 injured workers with chronic pain were subjected to confirmatory factor analysis. Results indicated that an intercorrelated three-factor model of the FQ provided a better fit to the data than unidimensional, two-factor, hierarchical three-factor, or categorical three-factor models. These findings provide further support for the factorial validity of the FQ and the corresponding multidimensional theory of fear. PMID:10356649

An emotion-differentiated perspective on empathy with the emotion specific empathy questionnaire  

PubMed Central

Empathy refers to the thoughts and feelings of one individual in response to the observed (emotional) experiences of another individual. Empathy, however, can occur toward persons experiencing a variety of emotions, raising the question of whether or not empathy can be emotion specific. This paper discusses theoretical and empirical support for the emotion specificity of empathy. We present a new measure, the Emotion Specific Empathy questionnaire, which assesses affective and cognitive empathy for the six basic emotions. This paper presents the measure's psychometric qualities and demonstrates, through a series of models, the discriminant validity between emotion specific empathies suggesting empathy is emotion specific. Results and implications are discussed. PMID:25071632

Salix response to different flow regimes in controlled experiments: first results  

NASA Astrophysics Data System (ADS)

Dams and water management for hydropower production, agriculture and other human activities alter the natural flow regime of rivers. The new river hydrograph components depend on the type of impoundment and the policy of regulation but such a different flow regime will likely affect the riparian environment. The main challenge in order to define sustainable flow releases is to quantify hydrological effects in terms of geomorphology and ecosystem response. A considerable lack of knowledge still affects the link hydrology-ecology and inadequate flow rules (e.g., minimal or residual flows) are consequently still widespread: further research in this direction is urgently required. We present an experiment, which aims to investigate the effects of different water stage regimes on riparian vegetation (salix Viminalis cuttings) development in a temperate region (Switzerland). This work describes the installation setup, together with the first results concerning the first of the two scheduled seasons of campaign. Sixty Salix cuttings were planted in non-cohesive sandy-gravel sediment within 1 meter tall plastic pots installed outside in the EPFL campus. After grouping them in three batteries, the water level within them has been varying following three river regimes simulated by adjusting the water level within the pots by means of an automatic hydraulic system. The three water level regimes reproduce a natural flow regime, a minimum residual flow policy, which only conserves peaks during flooding conditions, and an artificial regime conserving only low frequencies (e.g., seasonality) of the natural dynamic. The natural flow regime of the first battery has been applied for two months to the entire system; the three regimes above said started in June 2012. This triggered a plant response transitory regime, which we monitored by measuring plant growth, soil and atmospheric variables. Particularly, measures concern with branches development leaves photosynthesis and fluorescence, together with pictures of each plant. Sap flow was measured for thirty cuttings using a time resolution of thirty minutes, whereas psychrometers measuring the water potential were sampling data every fifteen minutes. Soil moisture and meteo data have also been collected as essential drivers of plant response: these data as well as sap flow measurements can be later compared to a similar field installation along Thur River (Switzerland). After the first season of measurement, in 2012, part of the cuttings have been carefully removed and further analyzed as far as the below ground biomass is concerned. Strong differences in terms of stress and growth performances were observed in correspondence of the transitional phase, following the alterations of the natural flow regime. A later adjustment in the roots distribution allowed survivors to re-sprout and to withstand new conditions.

Vessel noise affects beaked whale behavior: results of a dedicated acoustic response study.  

PubMed

Some beaked whale species are susceptible to the detrimental effects of anthropogenic noise. Most studies have concentrated on the effects of military sonar, but other forms of acoustic disturbance (e.g. shipping noise) may disrupt behavior. An experiment involving the exposure of target whale groups to intense vessel-generated noise tested how these exposures influenced the foraging behavior of Blainville's beaked whales (Mesoplodon densirostris) in the Tongue of the Ocean (Bahamas). A military array of bottom-mounted hydrophones was used to measure the response based upon changes in the spatial and temporal pattern of vocalizations. The archived acoustic data were used to compute metrics of the echolocation-based foraging behavior for 16 targeted groups, 10 groups further away on the range, and 26 non-exposed groups. The duration of foraging bouts was not significantly affected by the exposure. Changes in the hydrophone over which the group was most frequently detected occurred as the animals moved around within a foraging bout, and their number was significantly less the closer the whales were to the sound source. Non-exposed groups also had significantly more changes in the primary hydrophone than exposed groups irrespective of distance. Our results suggested that broadband ship noise caused a significant change in beaked whale behavior up to at least 5.2 kilometers away from the vessel. The observed change could potentially correspond to a restriction in the movement of groups, a period of more directional travel, a reduction in the number of individuals clicking within the group, or a response to changes in prey movement.

Results and lessons learned from radiological/nuclear emergency response exercise held in Québec, Canada.  

PubMed

The Ministry of Sustainable Development, Environment and Parks of Québec (Ministère du Développement durable, de l'Environnement et des Parcs du Québec-MDDEP) held a 3-d provincial nuclear emergency response exercise in September 2008 that saw participation from Canadian provincial and federal departments. Nuclear emergency exercises are regularly held in Québec, given the presence of the Gentilly-2 nuclear power plant situated in Bécancour on the St. Lawrence River. The significance of this exercise is that it marks the first exercise held in Canada where environmental samples spiked with relevant radioisotopes were analyzed during the exercise, both on-site and remotely, and where the results of those analyses had a direct impact on the decisions made during the exercise. Following the exercise, samples were sent to two other laboratories that are part of the Canadian National Nuclear Laboratory Network for analysis, providing the first intercomparison exercise for the Network. The results of the analysis of the air and drinking water samples, as well as the lessons learned during the exercise, are presented and discussed in this article. PMID:22470003

Background Depression and anxiety are two common normal responses to a chronic disease such as glaucoma. This study analysed the measurement properties of the depression screening instrument - Patient Health Questionnaire-9 (PHQ-9) using Rasch analysis to determine if it can be used as a measure. Methods In this hospital-based cross-sectional study, the PHQ-9 was administered to primary glaucoma adults attending a glaucoma clinic of a tertiary eye care centre, South India. All patients underwent a comprehensive clinical evaluation. Patient demographics and sub-type of glaucoma were abstracted from the medical record. Rasch analysis was used to investigate the following properties of the PHQ-9: behaviour of the response categories, measurement precision (assessed using person separation reliability, PSR; minimum recommended value 0.80), unidimensionality (assessed using item fit [0.7–1.3] and principal components analysis of residuals), and targeting. Results 198 patients (mean age ± standard deviation ?=?59.83±12.34 years; 67% male) were included. The native PHQ-9 did not fit the Rasch model. The response categories showed disordered thresholds which became ordered after category reorganization. Measurement precision was below acceptable limits (0.62) and targeting was sub-optimal (?1.27 logits). Four items misfit that were deleted iteratively following which a set of five items fit the Rasch model. However measurement precision failed to improve and targeting worsened further (?1.62 logits). Conclusions The PHQ-9, in its present form, provides suboptimal assessment of depression in patients with glaucoma in India. Therefore, there is a need to develop a new depression instrument for our glaucoma population. A superior strategy would be to use the item bank for depression but this will also need to be validated in glaucoma patients before deciding its utility. PMID:24999659

Watershed Responses to Changes In Mercury Loading: Results from the Terrestrial Aspects of the METAALICUS Project  

NASA Astrophysics Data System (ADS)

The METAALICUS project is a whole-ecosystem experiment specifically designed to quantify the magnitude and timing of the watershed response to a change in mercury (Hg) loading. A decade ago, when the US and many other countries began to consider Hg-specific emission regulations, many doubted the effectiveness of such actions since terrestrial soils and aquatic sediments were already ubiquitously contaminated, and would potentially sustain mercury loading to aquatic indefinitely. To address this question, a multi-national team of scientists was formed to devise a whole-ecosystem, Hg-dosing study, whereby Hg would be deliberately added to an entire watershed - The Mercury Experiment to Assess Atmospheric Loadings in Canada and the US (METAALICUS) project, conducted at the Experimental Lakes Area (ELA), northwestern Ontario, Canada. Whole-ecosystem manipulation studies have a distinct advantage over small-scale (lab scale) studies, in that all the ecosystem components, natural processes and complexities within watersheds are accounted for. This paper focuses on the terrestrial (upland forest and wetland) aspects of METAALICUS project, with particular emphasis on assessing the long-term response to a change in Hg loading. A very unique aspect of the METAALICUS project called for the use of three different stable isotopes to be applied to the lake, forests and wetland, respectively. This experimental approach not only allowed for the direct observation of responses (time and space) to changes in loading, but also provides never before realized resolution of pathways and processes of mercury in a watershed. Mercury additions to the terrestrial components of the watershed were initiated in 2001 and continued through 2006, at a rate of about 5x measured current atmospheric deposition. Since this time, METAALICUS has become a mercury reduction experiment, and thus we have been monitoring of the response to a Hg load cessation. During the loading phase of the project, the majority of the terrestrially applied Hg isotopes were distributed approximately equally among three major compartments: soils, plants (tree canopy and ground vegetation), and losses to emissions from soil and plant surfaces. Much less (about 1%) isotope was measured in runoff that flowed into the downstream lake. With each successive annual dose the isotope pool in soils steadily increased, while the forest canopy and emission fluxes pools had comparatively low carryover from year to year. Within two years of loading cessation, isotope concentrations in canopy and emission fluxes were negligible and about half of the total isotope load was found in soils. Isotope concentrations in runoff gradually increased during the loading phase, and continued to increase for 1-2 years after loading ceased, suggesting significant translocation from compartments above the forest floor. Three years subsequent to cessation, isotope concentrations in soils have remained steady, and generally reflect the Hg abundance of the overall soil pool. Models calibrated to these results will be very useful for scenario testing to evaluate long-term recovery of lakes with significant watershed Hg contributions.

Evaluation of a wind-tunnel gust response technique including correlations with analytical and flight test results  

NASA Technical Reports Server (NTRS)

A wind tunnel technique for obtaining gust frequency response functions for use in predicting the response of flexible aircraft to atmospheric turbulence is evaluated. The tunnel test results for a dynamically scaled cable supported aeroelastic model are compared with analytical and flight data. The wind tunnel technique, which employs oscillating vanes in the tunnel throat section to generate a sinusoidally varying flow field around the model, was evaluated by use of a 1/30 scale model of the B-52E airplane. Correlation between the wind tunnel results, flight test results, and analytical predictions for response in the short period and wing first elastic modes of motion are presented.

An informant questionnaire for detecting Alzheimer's disease: are some items better than others?  

PubMed

A decline in everyday cognitive functioning is important for diagnosing dementia. Informant questionnaires, such as the informant questionnaire on cognitive decline in the elderly (IQCODE), are used to measure this. Previously, conflicting results on the IQCODEs ability to discriminate between Alzheimer's disease (AD), mild cognitive impairment (MCI), and cognitively healthy elderly were found. We aim to investigate whether specific groups of items are more useful than others in discriminating between these patient groups. Informants of 180 AD, 59 MCI, and 89 patients with subjective memory complaints (SMC) completed the IQCODE. To investigate the grouping of questionnaire items, we used a two-dimensional graded response model (GRM).The association between IQCODE, age, gender, education, and diagnosis was modeled using structural equation modeling. The GRM with two groups of items fitted better than the unidimensional model. However, the high correlation between the dimensions (r=.90) suggested unidimensionality. The structural model showed that the IQCODE was able to differentiate between all patient groups. The IQCODE can be considered as unidimensional and as a useful addition to diagnostic screening in a memory clinic setting, as it was able to distinguish between AD, MCI, and SMC and was not influenced by gender or education.

Development and Validation of the Cognitive Behavioral Physical Activity Questionnaire.  

PubMed

Abstract Purpose . Develop and demonstrate preliminary validation of a brief questionnaire aimed at assessing social cognitive determinants of physical activity (PA) in a college population. Design . Quantitative and observational. Setting . A midsized northeastern university. Subjects . Convenience sample of 827 male and female college students age 18 to 24 years. Measures . International Physical Activity Questionnaire and a PA stage-of-change algorithm. Analysis . A sequential process of survey development, including item generation and data reduction analyses by factor analysis, was followed with the goal of creating a parsimonious questionnaire. Structural equation modeling was used for confirmatory factor analysis and construct validation was confirmed against self-reported PA and stage of change. Validation analyses were replicated in a second, independent sample of 1032 college students. Results . Fifteen items reflecting PA self-regulation, outcome expectations, and personal barriers explained 65% of the questionnaire data and explained 28.6% and 39.5% of the variance in total PA and moderate-to-vigorous-intensity PA, respectively. Scale scores were distinguishable across the stages of change. Findings were similar when the Cognitive Behavioral Physical Activity Questionnaire (CBPAQ) was tested in a similar and independent sample of college students (40%; R(2) moderate-to-vigorous-intensity PA = .40; p < .001). Conclusion . The CBPAQ successfully explains and predicts PA behavior in a college population, warranting its incorporation into future studies aiming at understanding and improving on PA behavior in college students.

Individual significance of olfaction: development of a questionnaire.  

PubMed

Clinical experience shows that the individual significance of olfactory function varies between subjects. In order to estimate these individual differences we developed a questionnaire to study the subjective importance of the sense of smell. Questions were arranged within three subscales: association with olfactory sensations, application of the sense of smell, and the readiness to draw consequences from the olfactory perception. The questionnaire was shown to be time efficient, suitable for normosmic subjects and patients with hyposmia or anosmia. It exhibited a good internal reliability (Cronbach's Alpha = 0.77). First results in 123 subjects indicate that the subjective importance of the sense of smell stays at the same level throughout life-span despite of a decreased olfactory sensitivity. Furthermore, women reported a higher importance of olfaction. It is hoped that this questionnaire will contribute to clarify, for example, cross-cultural differences in the perception of odours.

Biological responses to space: results of the experiment ``exobiological unit'' of ERA on EURECA I  

NASA Astrophysics Data System (ADS)

Spores of different strains of Bacillus subtilis and the Escherichia coli plasmid pUC19 were exposed to selected conditions of space (space vacuum and/or defined wavebands and intensities of solar ultraviolet radiation) in the experiment ER 161 ``Exobiological Unit'' of the Exobiology Radiation Assembly (ERA) on board of the European Retrievable Carrier (EURECA). After the approximately 11 months lasting mission, their responses were studied in terms of survival, mutagenesis in the his (B. subtilis) or lac locus (pUC19), induction of DNA strand breaks, efficiency of DNA repair systems, and the role of external protective agents. The data were compared with those of a simultaneously running ground control experiment. The survival of spores treated with the vacuum of space, however shielded against solar radiation, is substantially increased, if they are exposed in multilayers and/or in the presence of glucose as protective, whereas all spores in ``artificial meteorites'', i.e. embedded in clays or simulated Martian soil, are killed. Vacuum treatment leads to an increase of mutation frequency in spores, but not in plasmid DNA. Extraterrestrial solar ultraviolet radiation is mutagenic, induces strand breaks in the DNA and reduces survival substantially; however, even at the highest fluences, i.e. 3 x 10^8 Jm^-2, a small but significant fraction of spores survives the insolation. Action spectroscopy confirms results of previous space experiments of a synergistic action of space vacuum and solar UV radiation with DNA being the critical target.

Development and validation of the living with pulmonary hypertension questionnaire in pulmonary arterial hypertension patients  

PubMed Central

Background The Living with Pulmonary Hypertension questionnaire (LPH) was adapted from the Minnesota Living with Heart Failure Questionnaire for use in patients with pulmonary arterial hypertension (PAH). Study objectives were to confirm the face and content validity, to assess the structure and psychometric properties, and provide guidance for the interpretation of the LPH. Methods A qualitative interview study was conducted with PAH patients in the US (n=12), Germany (n=14) and France (n=12) to evaluate the face and content validity of the LPH. Psychometric validation was performed using blinded data from a double blind, Phase III, clinical trial (n=196). Validation analyses were performed on baseline and week 12 (visit 6/last visit) data and included evaluation of: item response distributions, quality of completion, construct validity, reliability, clinical validity and responsiveness. Analyses to provide an estimation of the Minimal Important Difference (MID) for the LPH scores were performed. Results Cognitive debriefing interviews with 38 PAH patients indicated that the most commonly reported PAH symptoms and impacts are covered by LPH items. Patients found the LPH questionnaire relevant and comprehensive to their experience. Some suggestions were made to enhance the face validity of the LPH. The content validity of the questionnaire was supported. Results of the psychometric validation analyses (n=190) indicated that the LPH Emotional and Physical scores met the criteria for convergent and discriminant validity; for the total score all but two items met the test for item convergent validity. Internal consistency reliability was demonstrated by Cronbach’s alpha values of >0.70 for all LPH scores. The LPH Physical and Total scores discriminated between World Health Organisation (WHO) Functional classes and 6 Minute walk test distances, indicating clinical validity and were also responsive to change in clinical severity, as measured by change in WHO functional class and Borg CR 10 Scale. Further investigation is required to confirm the responsiveness of the Emotional score. Estimation of MID using distribution-based methods indicated a change of 3 points for the sub-scales and 7 for the total score to be clinically meaningful. Conclusion The LPH is a valid and reliable instrument that meets FDA criteria. PMID:24088389

Screening Questionnaires for Parkinsonism: A Systematic Review  

PubMed Central

Parkinson’s disease (PD) is a common, treatable movement disorder that often remains undiagnosed despite clinically manifest symptoms. Screening for parkinsonism could lead to improved detection and earlier treatment, and facilitate research studies of PD prevalence. In order to determine the feasibility of screening, this study evaluated the validity of previously developed screening questionnaires. We systematically searched online databases PubMed and EMBASE for English-language studies published between 1980 and 2009. In each database a “Parkinson(s) disease” or “parkinsonism” term was combined with a screening term (“screening instrument,” screening questionnaire,” “screen” or “prevalence survey”) and a validity term (“validation,” “sensitivity” and “specificity”). Included studies reported the psychometric properties of at least one self-report questionnaire for parkinsonism. Twenty-seven studies met the inclusion criteria. From these studies, 9 screening questionnaires were identified. Sensitivity and specificity estimates varied widely. Sensitivity estimates were as high as 100% when questionnaires were tested among previously diagnosed PD patients and included a high number of parkinsonism-specific items, but were as low as 48% when tested among early cases in a community-based sample. Specificity estimates were lower, ranging from 22–100%. An older sample, presence of multiple co-morbid conditions and lower literacy led to lower specificity estimates. Higher specificity estimates were seen when the screening questionnaires were administered by a physician. Screening questionnaires can detect symptomatic parkinsonism. However, the performance of these questionnaires varied based on the individual items, study sample, and method of administration. The performance of screening questionnaires in the detection of early or mild parkinsonism was modest. PMID:21930414

The human response to artificial gravity in a weightless environment: Results from the Neurolab centrifugation experiments  

NASA Astrophysics Data System (ADS)

On Earth, afferent otolith activity encodes head tilt with respect to gravity, as well as head linear acceleration. The vector sum of head acceleration and gravity, termed gravito-inertial acceleration (GIA), is used by the vestibular system to generate the perception of vertical, ocular counter-rolling (OCR), and vertical or roll components of nystagmus, which orient the axis of eye velocity towards alignment with the GIA. Head tilt is not sensed by the otoliths in microgravity, but the otoliths are still activated by translation. It has therefore been proposed that the brain reinterprets tilt-related otolith information as translation during space flight. During the 1998 Neurolab mission, 4 astronauts were exposed to inter-aural (IA) and body vertical (Z-axis) centripetal accelerations of 0.5 and 1-g by rotation in an off-axis centrifuge. During rotation, binocular 3D eye movements were measured using a video technique with the subject in darkness and while viewing an optokinetic stimulus. On Earth, 1-g centrifugation tilts the GIA 45° with respect to the head, and pre-flight perception of roll tilt was 35°. By flight day 5, all astronauts perceived ~90° of roll tilt in response to a constant 1-g IA linear acceleration. This tilt angle was under-reported early in flight, and over-estimated on return to Earth, possibly due to adaptation of otolith and/or somatosensory function during transition to the new gravitational states. Tilt perception was proportionally lower during 0.5-g centrifugation, both pre-flight (20°) and in-flight (46°). Similar results were obtained for pitch tilt perception during Z-axis centrifugation. The magnitude of OCR in response to the GIA during IA centrifugation was unchanged in microgravity, and was proportional to the centripetal acceleration. This suggests that both OCR and roll tilt perception are strongly dependent on the magnitude of IA linear acceleration, as in microgravity there is no body vertical (Z-axis) linear acceleration. The axis of eye velocity during both horizontal optokinetic nystagmus and angular acceleration in darkness tended to align with the GIA, as on Earth. In space, low frequency otolith information is not reinterpreted as translation, and constant 1-g linear acceleration is sensed as being equivalent to gravity. .

Development of the Comprehensive General Parenting Questionnaire for caregivers of 5-13 year olds  

PubMed Central

Background Despite the large number of parenting questionnaires, considerable disagreement exists about how to best assess parenting. Most of the instruments only assess limited aspects of parenting. To overcome this shortcoming, the “Comprehensive General Parenting Questionnaire” (CGPQ) was systematically developed. Such a measure is frequently requested in the area of childhood overweight. Methods First, an item bank of existing parenting measures was created assessing five key parenting constructs that have been identified across multiple theoretical approaches to parenting (Nurturance, Overprotection, Coercive control, Behavioral control, and Structure). Caregivers of 5- to 13-year-olds were asked to complete the online survey in the Netherlands (N?=?821), Belgium (N?=?435) and the United States (N?=?241). In addition, a questionnaire regarding personality characteristics (“Big Five”) of the caregiver was administered and parents were asked to report about their child’s height and weight. Factor analyses and Item-Response Modeling (IRM) techniques were used to assess the underlying parenting constructs and for item reduction. Correlation analyses were performed to assess the relations between general parenting and personality of the caregivers, adjusting for socio-economic status (SES) indicators, to establish criterion validity. Multivariate linear regressions were performed to examine the associations of SES indicators and parenting with child BMI z-scores. Additionally, we assessed whether scores on the parenting constructs and child BMI z-scores differed depending on SES indicators. Results The reduced questionnaire (62 items) revealed acceptable fit of our parenting model and acceptable IRM item fit statistics. Caregiver personality was related as hypothesized with the GCPQ parenting constructs. While correcting for SES, overprotection was positively related to child BMI. The negative relationship between structure and BMI was borderline significant. Parents with a high level of education were less likely to use overly forms of controlling parenting (i.e., coercive control and overprotection) and more likely to have children with lower BMI. Based on several author review meetings and cognitive interviews the questionnaire was further modified to an 85-item questionnaire. Conclusions The GCPQ may facilitate research exploring how parenting influences children’s weight-related behaviors. The contextual influence of general parenting is likely to be more profound than its direct relationship with weight status. PMID:24512450

The VSQ: a questionnaire to measure vulvovaginal symptoms in postmenopausal women  

PubMed Central

Objective The purpose of this study was to develop a vulvovaginal symptoms questionnaire (VSQ) to study symptoms, emotions, life-impact, and sexual-impact of vulvovaginal symptoms in postmenopausal women. Methods We developed questionnaire focused on vulvovaginal symptoms based on modifications to the Skindex-16, a validated questionnaire to measure the impact of skin disease. We then recruited postmenopausal women seeking routine gynecologic care to test the psychometric properties of the VSQ. Test-retest reliability was assessed 2 to 4 weeks after their initial recruitment and measured utilizing intra-class coefficients. Four distinct a priori scales of the VSQ were developed: symptoms, emotions, life-impact, and sexual-impact. Confirmatory factor analysis was performed to verify the four a priori scales by evaluating the goodness-of-fit of a final confirmatory factor analysis model. The internal consistency of the scales was assessed through the calculation of Cronbach’s ? coefficient. Results The VSQ is a 21-item written questionnaire with four scales, symptoms, emotions, life-impact, and sexual impact. One hundred twenty postmenopausal women participated in the psychometric validation of the VSQ. The test-retest reliability the four scales measured by intra-class coefficients were 0.75, 0.60, 0.55, and 0.65 for symptoms, emotions, life-impact and sexual-impact. The goodness-of –fit of the confirmatory factor response model was confirmed. Cronbach’s ? coefficients were 0.76, 0.87, 0.83, and 0.82 for the scales. Conclusion The VSQ is a reliable and internal consistent instrument to measure vulvovaginal symptoms in postmenopausal women. PMID:23481118

Evaluating the organisational climate in Italian public healthcare institutions by means of a questionnaire  

PubMed Central

Background By means of the ICONAS project, the Healthcare Agency of an Italian Region developed, and used a standardised questionnaire to quantify the organisational climate. The aims of the project were (a) to investigate whether the healthcare institutions were interested in measuring climate, (b) to estimate the range of applicability and reliability of the instrument, (c) to analyse the dimensions of climate among healthcare personnel, (d) to assess the differences among employees with different contractual positions. Methods The anonymous questionnaire containing 50 items, each with a scale from 1 to 10, was offered to the healthcare organisations, to be compiled during ad hoc meetings. The data were sent to the central project coordinator. The differences between highly specialised staff (mostly physicians) and other employees were assessed after descriptive statistical analysis of the single items. Both Principal Component Analysis and Factor Analysis were used. Results Ten healthcare organisations agreed to partecipate. The questionnaire was completed by 8691 employees out of 13202. The mean value of organisational climate was 4.79 (range 1–10). There were significant differences among single items and between the 2 groups of employees. Multivariate methods showed: (a) one principal component explained > 40% of the variance, (b) 7 factors summarised the data. Conclusion Italian healthcare institutions are interested in assessing organisational phenomena, especially after the reforms of the nineties. The instrument was found to be applicable and suitable for measuring organisational climate. Administration of the questionnaire leads to an acceptable response rate. Climate can be discribed by means of 7 underlying dimensions. PMID:17519007

Can we identify response markers to antihypertensive drugs? First results from the IDEAL Trial.  

PubMed

Current antihypertensive strategies do not take into account that individual characteristics may influence the magnitude of blood pressure (BP) reduction. Guidelines promote trial-and-error approaches with many different drugs. We conducted the Identification of the Determinants of the Efficacy of Arterial blood pressure Lowering drugs (IDEAL) Trial to identify factors associated with BP responses to perindopril and indapamide. IDEAL was a cross-over, double-blind, placebo-controlled trial, involving four 4-week periods: indapamide, perindopril and two placebo. Eligible patients were untreated, hypertensive and aged 25-70 years. The main outcome was systolic BP (SBP) response to drugs. The 112 participants with good compliance had a mean age of 52. One in every three participants was a woman. In middle-aged women, the SBP reduction from drugs was -11.5?mm?Hg (indapamide) and -8.3?mm?Hg (perindopril). In men, the response was significantly smaller: -4.8?mm?Hg (indapamide) and -4.3 (perindopril) (P for sex differences 0.001 and 0.015, respectively). SBP response to perindopril decreased by 2?mm?Hg every 10 years of age in both sexes (P=0.01). The response to indapamide increased by 3?mm?Hg every 10 years of age gradient in women (P=0.02). Age and sex were important determinants of BP response for antihypertensive drugs in the IDEAL population. This should be taken into account when choosing drugs a priori. PMID:24739801

Validation of a Persian Version of Motorcycle Rider Behavior Questionnaire  

PubMed Central

In Iran, road traffic injuries are the first cause of burden of disease and motorcyclists are the most vulnerable road users. Elliot and colleagues developed the “Motorcycle Rider Behavior Questionnaire” (MRBQ), on the basis of Reason’s “Driver Behavior Questionnaire” (DBQ) in 2007. The purpose of this study was to assess the validity and reliability of a Persian version of MRBQ. The 43-item MRBQ was adapted to Persian according to translation-back translation method. The questionnaire was significantly revised after assessment of content validity. In the revised version, 10 items of original MRBQ were deleted and 15 new items were added. The revised MRBQ was used in a survey of 518 motorcyclists. To assess the construct validity of MRBQ, we used Buss-Perry Aggression questionnaire concurrently on all of the subjects. After three weeks, we carried out the retest study on 119 out of 518 subjects. The mean age of the subjects was 32.5 years (SD=8.8). All of the participants were male with mean of 9.3 years of motorcycle riding experience (SD=7.3). Principal Components Analysis (PCA) showed six subscales: “Speed Violations”, “Traffic Errors”, “Safety Violations”, “Traffic Violations”, “Stunts” and “Control Errors”, which accounted for 36.44% of total variance together. For each of these subscales, Cronbach’s Alpha was between 0.79 to 0.91. Intraclass Correlation Coefficient for six subscales and total questionnaire were from 0.73 to 0.91. There were significant correlations between MRBQ subscales and subscales of Buss-Perry aggression questionnaire. The results indicated that the 48-item Persian version of MRBQ is a suitable measure for studying motorcyclists’ behavior. PMID:22105387

Measuring the effects of online health information for patients: Item generation for an e-health impact questionnaire  

PubMed Central

Objective The internet is a valuable resource for accessing health information and support. We are developing an instrument to assess the effects of websites with experiential and factual health information. This study aimed to inform an item pool for the proposed questionnaire. Methods Items were informed through a review of relevant literature and secondary qualitative analysis of 99 narrative interviews relating to patient and carer experiences of health. Statements relating to identified themes were re-cast as questionnaire items and shown for review to an expert panel. Cognitive debrief interviews (n = 21) were used to assess items for face and content validity. Results Eighty-two generic items were identified following secondary qualitative analysis and expert review. Cognitive interviewing confirmed the questionnaire instructions, 62 items and the response options were acceptable to patients and carers. Conclusion Using a clear conceptual basis to inform item generation, 62 items have been identified as suitable to undergo further psychometric testing. Practice implications The final questionnaire will initially be used in a randomized controlled trial examining the effects of online patient's experiences. This will inform recommendations on the best way to present patients’ experiences within health information websites. PMID:23598293

Development and validity of a questionnaire to test the knowledge of primary care personnel regarding nutrition in obese adolescents  

PubMed Central

Background In light of its epidemic proportions in developed and developing countries, obesity is considered a serious public health issue. In order to increase knowledge concerning the ability of health care professionals in caring for obese adolescents and adopt more efficient preventive and control measures, a questionnaire was developed and validated to assess non-dietitian health professionals regarding their Knowledge of Nutrition in Obese Adolescents (KNOA). Methods The development and evaluation of a questionnaire to assess the knowledge of primary care practitioners with respect to nutrition in obese adolescents was carried out in five phases, as follows: 1) definition of study dimensions 2) development of 42 questions and preliminary evaluation of the questionnaire by a panel of experts; 3) characterization and selection of primary care practitioners (35 dietitians and 265 non-dietitians) and measurement of questionnaire criteria by contrasting the responses of dietitians and non-dietitians; 4) reliability assessment by question exclusion based on item difficulty (too easy and too difficult for non-dietitian practitioners), item discrimination, internal consistency and reproducibility index determination; and 5) scoring the completed questionnaires. Results Dietitians obtained higher scores than non-dietitians (Mann–Whitney U test, P?questionnaire criteria. Items were discriminated by correlating the score for each item with the total score, using a minimum of 0.2 as a correlation coefficient cutoff value. Item difficulty was controlled by excluding questions answered correctly by more than 90% of the non-dietitian subjects (too easy) or by less than 10% of them (too difficult). The final questionnaire contained 26 of the original 42 questions, increasing Cronbach’s ? value from 0.788 to 0.807. Test-retest agreement between respondents was classified as good to very good (Kappa test, >0.60). Conclusion The KNOA questionnaire developed for primary care practitioners is a valid, consistent and suitable instrument that can be applied over time, making it a promising tool for developing and guiding public health policies.

Treatment with sirolimus results in complete responses in patients with autoimmune lymphoproliferative syndrome  

PubMed Central

Summary We hypothesized that sirolimus, an mTOR inhibitor, may be effective in patients with autoimmune lymphoproliferative syndrome (ALPS) and treated patients who were intolerant to or failed other therapies. Four patients were treated for autoimmune cytopenias; all had a rapid complete or near complete response. Two patients were treated for autoimmune arthritis and colitis, demonstrating marked improvement. Three patients had complete resolution of lymphadenopathy and splenomegaly and all patients had a reduction in double negative T cells, a population hallmark of the disease. Based on these significant responses, we recommend that sirolimus be considered as second-line therapy for patients with steroid-refractory disease. PMID:19208097

Pregnancy in Multiple Sclerosis: A Questionnaire Study  

PubMed Central

Background Multiple sclerosis (MS) preferentially affects females at childbearing age. For this reason patients and treating physicians were frequently confronted with questions concerning family planning, pregnancy and birth. Objective The aim of this study was to evaluate the expertise about pregnancy related topics in multiple sclerosis of neurologists in private practice. Methods We developed a survey with 16 multiple choice questions about pregnancy related topics and sent it to neurologists in private practice in Berlin, Germany. Results 56 completed questionnaires were sent back. 54% of all questions were answered correctly, 21% of the questions were answered with “I don’t know”. Correct answers were more often given by physicians who treat more than 400 MS patients per year (p?=?0.001). Further positive associations were found for assumed relevance of the topic (p?=?0.002) and the degree of counseling (p<0.001). Conclusion To provide a comprehensive counseling, MS patients with desire for children should be counseled by physicians with a lot of experience in MS treatment. PMID:24901447

The Manchester–Oxford Foot Questionnaire (MOXFQ)  

PubMed Central

Objectives The Manchester–Oxford Foot Questionnaire (MOXFQ) is a validated 16-item, patient-reported outcome measure for evaluating outcomes of foot or ankle surgery. The original development of the instrument identified three domains. This present study examined whether the three domains could legitimately be summed to provide a single summary index score. Methods The MOXFQ and Short-Form (SF)-36 were administered to 671 patients before surgery of the foot or ankle. Data from the three domains of the MOXFQ (pain, walking/standing and social interaction) were subjected to higher order factor analysis. Reliability and validity of the summary index score was assessed. Results The mean age of the participants was 52.8 years (sd 15.68; 18 to 89). Higher order principle components factor analysis produced one factor, accounting for 74.7% of the variance. The newly derived single index score was found to be internally reliable (? = 0.93) and valid, achieving at least moderate correlations (r ? 0.5, p < 0.001) with related (pain/function) domains of the SF-36. Conclusions Analyses indicated that data from the MOXFQ can be presented in summary form. The MOXFQ summary index score (MOXFQ-Index) provides an overall indication of the outcomes of foot and ankle surgery. Furthermore, the single index reduces the number of statistical comparisons, and hence the role of chance, when exploring MOXFQ data. PMID:23673374

A questionnaire-based survey of errors in diagnostic histopathology throughout the United Kingdom.  

PubMed Central

AIMS: To obtain a crude estimate of the rate at which consultant histopathologists become aware of errors in their work, and to gather information about the circumstances under which errors are made. METHODS: A postal questionnaire was sent to all consultant histopathologists (1021) in the United Kingdom. RESULTS: There was a 19.8% response to the questionnaire (202 returned). 119 pathologists reported 244 errors, 82 from within the preceding year. 42% of these errors had affected patient management. Pathologists usually blamed human error or excessive workload; however, data analysis did not reveal an excess of responses from laboratories with heavy workloads. A disproportionately large proportion of errors appear to be made in samples from the lymphoreticular system and by locum consultant pathologists. CONCLUSIONS: This study undoubtedly suffered from reporting bias, but the figures suggest that a typical pathologist probably becomes aware of having made a serious diagnostic error approximately once per year. A larger, more systematic study of the circumstances under which errors are likely to occur appears to be justified but would require significant resources because of the large sample size required.

Wild edible plants of Belarus: from Rostafi?ski’s questionnaire of 1883 to the present  

PubMed Central

Background Belarus is an Eastern European country, which has been little studied ethnobotanically. The aim of the study was to compare largely unpublished 19th century sources with more contemporary data on the use of wild food plants. Methods The information on 19th century uses is based on twelve, mainly unpublished, responses to Józef Rostafi?ski’s questionnaire from 1883, and the newly discovered materials of the ethnographer Micha? Federowski, who structured his data according to Rostafi?ski’s questionnaire and documented it with voucher specimens. Rostafi?ski’s questionnaire was concerned mainly with Polish territories, but for historical reasons this also encompassed a large part of Belarus, and we analyzed only the twelve responses (out of the few hundred Rostafi?ski obtained), which concerned the present Belarus. These data were compared with a few 20th century ethnographic sources, and our own 40 interviews and questionnaires from Belarus. Results and discussion 58 taxa of wild food plants used in the 19th century were identified. Some of them are still used in modern Belarus, others are probably completely forgotten. In the 19th century several species of wild greens were widely used for making soups. Apart from Rumex, other wild greens are now either forgotten or rarely used. The list of species used in the 20th and 21st century encompasses 67 taxa. Nearly half of them were mentioned by Rostafi?ski’s respondents. The list of fruit species has not changed much, although in the 19th century fruits were mainly eaten raw, or with dairy or floury dishes, and now apart from being eaten raw, they are incorporated in sweet dishes like jams or cakes. Modern comparative data also contain several alien species, some of which have escaped from cultivation and are gathered from a semi-wild state, as well as children's snacks, which were probably collected in the 19th century but were not recorded back then. Conclusion The responses to Rostafi?ski from 1883 present extremely valuable historical material as the use of wild food plants in Belarus has since undergone drastic changes, similar to those, which have taken place in other Eastern European countries.

Validation of a self-administered questionnaire for assessing occupational and environmental exposures of pregnant women  

SciTech Connect

The present investigation sought to determine whether a self-administered questionnaire could be used to obtain occupational information from pregnant women attending the obstetrical clinics at the University of California, San Francisco from July to November 1986. The authors compared the accuracy of responses of 57 women on the self-administered questionnaire with those obtained on a detailed clinical interview by an occupational health professional. The self-administered questionnaire and the clinical interview included information on the woman's job title, the type of company she worked for, the level of physical activity, her exposures on the job and at home, and her partner's occupation. The authors also examined whether the validity of the self-administered questionnaire could be improved on review by an industrial hygienist. The questionnaire took less than 20 minutes to complete, with over 90% of the women answering three-quarters of it. It was substantially accurate in obtaining information on number of hours worked during pregnancy, type of shift worked, and stress level in the workplace; exposure to radiation, video display terminals, fumes, gases, and cigarette smoke in the workplace; and exposure to pesticides, paint, and cigarette smoke at home. On those variables for which the responses on the self-administered questionnaire were less accurate, review by the industrial hygienist improved the level of accuracy considerably. These findings suggest that a self-administered questionnaire can be used to obtain valid information from pregnant women attending a prenatal clinic.

Response Modeling of Lightweight Charring Ablators and Thermal Radiation Testing Results  

NASA Technical Reports Server (NTRS)

Under NASA's In-Space Propulsion/Aerocapture Program, ARA conducted arc-jet and thermal-radiation ablation test series in 2003 for advanced development, characterization, and response modeling of SRAM-20, SRAM-17, SRAM-14, and PhenCarb-20 ablators. Testing was focused on the future Titan Explorer mission. Convective heating rates (CW) were as high as 153 W/sq cm in the IHF and radiation rates were 100 W/sq cm in the Solar Tower Facility. The ablators showed good performance in the radiation environment without spallation, which was initially a concern, but they also showed higher in-depth temperatures when compared to analytical predictions based on arc-jet thermal-ablation response models. More testing in 2003 is planned in both of these facility to generate a sufficient data base for Titan TPS engineering.

Recombinant rabies virus expressing IFN?1 enhanced immune responses resulting in its attenuation and stronger immunogenicity.  

PubMed

Several studies have shown that type 1 interferons (IFNs) exert multiple biological effects on both innate and adaptive immune responses. Here, we investigated the pathogenicity and immunogenicity of recombinant rabies virus (RABV) expressing canine interferon ?1 (rHEP-CaIFN?1). It was shown that Kun Ming (KM) mice that received a single intramuscular immunization with rHEP-CaIFN?1 had an earlier increase and a higher level of virus-neutralizing antibody titers compared with immunization of the parent HEP-Flury. A challenge experiment further confirmed that more mice that were immunized with rHEP-CaIFN?1 survived compared with mice immunized with the parent virus. Quantitative real-time PCR indicated that rHEP-CaIFN?1 induced a stronger innate immune response, especially the type 1 IFN response. Flow cytometry was conducted to show that rHEP-CaIFN?1 recruited more activated B cells in lymph nodes and CD8 T cells in the peripheral blood, which is beneficial to achieve virus clearance in the early infective stage.

Fed State Prior to Hemorrhagic Shock and Polytrauma in a Porcine Model Results in Altered Liver Transcriptomic Response  

PubMed Central

Hemorrhagic shock is a leading cause of trauma-related mortality in both civilian and military settings. Resuscitation often results in reperfusion injury and survivors are susceptible to developing multiple organ failure (MOF). The impact of fed state on the overall response to shock and resuscitation has been explored in some murine models but few clinically relevant large animal models. We have previously used metabolomics to establish that the fed state results in a different metabolic response in the porcine liver following hemorrhagic shock and resuscitation. In this study, we used our clinically relevant model of hemorrhagic shock and polytrauma and the Illumina HiSeq platform to determine if the liver transcriptomic response is also altered with respect to fed state. Functional analysis of the response to shock and resuscitation confirmed several typical responses including carbohydrate metabolism, cytokine inflammation, decreased cholesterol synthesis, and apoptosis. Our findings also suggest that the fasting state, relative to a carbohydrate prefed state, displays decreased carbohydrate metabolism, increased cytoskeleton reorganization and decreased inflammation in response to hemorrhagic shock and reperfusion. Evidence suggests that this is a consequence of a shrunken, catabolic state of the liver cells which provides an anti-inflammatory condition that partially mitigates hepatocellar damage.

[Internal statistical validation of a quality of life questionnaire].  

PubMed

In this paper we present two different statistical approaches to evaluate the psychometric properties of a quality of life questionnaire. First the study of the factorial structure is briefly exposed. Then we present the unidimensional classical models. They are based on the linear relationship between the observed score and the true score. The definition of the reliability was first addressed in this classical framework. Its estimation with the Cronbach alpha coefficient is one important feature of the evaluation of an instrument. More recently, modern response theory gives a better statistical framework to deal with unidimensional latent traits. These models describe the probability of positive answer to an item as a function of the actual value of the latent trait and an item parameter. We expose the principles of the Rasch model: hypothesis, estimations methods and fit tests. Finally practical applications to the validation process of a questionnaire are explored with data from a study of a short French version of the SIP questionnaire. PMID:10673591

Sources of nonresponse to the Federal Waterfowl Hunter Questionnaire Survey  

USGS Publications Warehouse

Response rates to the Federal Waterfowl Hunter Questionnaire Survey (WHQS) have declined since the 1950's, suggesting that harvest estimates may be biased. Consequently, we investigated reasons for WHQS nonresponse using surveys of waterfowl hunters in Arkansas, California, Louisiana, Minnesota, New Jersey, and Texas [USA]. Sampling frames were constructed using lists of buyers of state hunting licenses or state duck stamps. We mailed questionnaires to 16,452 randomly selected hunters, with 2 follow-up mailings at 3-week intervals. Questionnaires were completed by 8,812 respondents, and a further 587 interviews were conducted by telephone. Post offices accounted for between 53.7% (Minn.) and 92.8% (N.J.) of federal waterfowl duck stamp sales, and stores accounted for most other sales. Of hunters who bought a federal waterfowl stamp from sample post offices, between 16.7% (Minn.) and 40.0% (Ark.) reported receiving a WHQS contact card. Of those receiving contact cards, between 30.0% (N.J.) and 64.3% (La. and Tex.) reported returning them. Because survey coverage of the target population is poor, we recommend that a new sampling frame be developed for the WHQS.

Measuring quality of life in psoriasis: the CALIPSO questionnaire.  

PubMed

In dermatology, several instruments are available to measure health-related quality of life (HRQoL) of patients. They vary in content emphasis and in the extent to which their measurement properties have been investigated and reported. In this study, we summarized five dermatology- and psoriasis-specific HRQoL questionnaires into a new psoriasis-specific questionnaire, the Comprehensive Appraisal of Life Impact of PSOriasis (CALIPSO). The questionnaires were completed by 936 patients with a diagnosis of psoriasis. Rasch's unidimensional measurement model was used to verify the construct validity and the operational characteristics of each instrument separately. The items with the best performance according to the Rasch model were selected. The final 30 items constitute the CALIPSO. Responses are given on a 3-point scale: "never", "sometimes/quite frequently", "often/all the time". The properties of the CALIPSO now need to be verified through the analysis of new data from different populations of people with psoriasis. In future, clinicians may use it without having to decide amongst several competing scales, to evaluate HRQoL in patients with psoriasis. PMID:21245022

Self-reported responsiveness to direct-to-consumer drug advertising and medication use: results of a national survey  

PubMed Central

Background Direct-to-consumer (DTC) marketing of pharmaceuticals is controversial, yet effective. Little is known relating patterns of medication use to patient responsiveness to DTC. Methods We conducted a secondary analysis of data collected in national telephone survey on knowledge of and attitudes toward DTC advertisements. The survey of 1081 U.S. adults (response rate = 65%) was conducted by the Food and Drug Administration (FDA). Responsiveness to DTC was defined as an affirmative response to the item: "Has an advertisement for a prescription drug ever caused you to ask a doctor about a medical condition or illness of your own that you had not talked to a doctor about before?" Patients reported number of prescription and over-the-counter (OTC) medicines taken as well as demographic and personal health information. Results Of 771 respondents who met study criteria, 195 (25%) were responsive to DTC. Only 7% respondents taking no prescription were responsive, whereas 45% of respondents taking 5 or more prescription medications were responsive. This trend remained significant (p trend .0009) even when controlling for age, gender, race, educational attainment, income, self-reported health status, and whether respondents "liked" DTC advertising. There was no relationship between the number of OTC medications taken and the propensity to discuss health-related problems in response to DTC advertisements (p = .4). Conclusion There is a strong cross-sectional relationship between the number of prescription, but not OTC, drugs used and responsiveness to DTC advertising. Although this relationship could be explained by physician compliance with patient requests for medications, it is also plausible that DTC advertisements have a particular appeal to patients prone to taking multiple medications. Outpatients motivated to discuss medical conditions based on their exposure to DTC advertising may require a careful medication history to evaluate for therapeutic duplication or overmedication.

Identifying Provider Beliefs Related to Contingency Management Adoption Using the Contingency Management Beliefs Questionnaire  

PubMed Central

Background Contingency management (CM) is a widely recognized empirically-supported addiction treatment; however, dissemination and adoption of CM into routine clinical practice has been slow. Assessment of beliefs about CM may highlight key barriers and facilitators of adoption and inform dissemination efforts. In the present study, we developed a 35-item questionnaire (Contingency Management Beliefs Questionnaire; CMBQ) assessing CM beliefs and examined the relation of these beliefs to clinician characteristics and clinical practices. Methods The web-based study was completed by 617 substance abuse treatment providers. We examined the factor structure using exploratory factor analysis (EFA) in a randomly selected half-sample (n =318) and evaluated the generalizability of the solution using confirmatory factor analysis (CFA) in the second half-sample (n = 299). Results EFA results suggested a 3-factor solution with 32 items retained; factors represented general barriers, training-related barriers, and pro-CM items. CFA results supported the solution, and reliability was good within each half-sample (? = .88 and 0.90). Therapeutic approach, years experience in addictions field, perception of CM’s research support, prior CM training, and CM adoption interest were significantly associated with the factors. Conclusions Overall, participants viewed CM favorably yet endorsed barriers, indicating a need for more extensive and targeted response to the most common misperceptions in dissemination efforts.

Stimuli-responsive topological change of microstructured surfaces and the resultant variations of wetting properties.  

PubMed

It is now well established that topological microstructures play a key role in the physical properties of surfaces. Stimulus-induced variations of topological microstructure should therefore lead to a change in the physical properties of microstructured responsive surfaces. In this paper, we demonstrate that roughness changes alter the wetting properties of responsive organic surfaces. Oriented nematic liquid crystalline elastomers (LCEs) are used to construct the microstructured surfaces via a replica molding technique. The topological microstructure of the surfaces covered with micropillars changes with temperature, due to the reversible contraction of the LCE pillars along the long axis at the nematic-to-isotropic phase transition. This is directly observed for the first time under environmental scanning electron microscopy (E-SEM). A high boiling point liquid, glycerol, is used to continuously monitor the contact angle change with temperature. The glycerol contact angle of the microstructured surfaces covered with small pillars decreases from 118° at room temperature to 80° at 140 °C, corresponding to a transition from Cassie state to Wenzel state.

Lacustrine responses to decreasing wet mercury deposition rates: results from a case study in northern Minnesota  

USGS Publications Warehouse

We present a case study comparing metrics of methylmercury (MeHg) contamination for four undeveloped lakes in Voyageurs National Park to wet atmospheric deposition of mercury (Hg), sulfate (SO4–2), and hydrogen ion (H+) in northern Minnesota. Annual wet Hg, SO4–2, and H+ deposition rates at two nearby precipitation monitoring sites indicate considerable decreases from 1998 to 2012 (mean decreases of 32, 48, and 66%, respectively). Consistent with decreases in the atmospheric pollutants, epilimnetic aqueous methylmercury (MeHgaq) and mercury in small yellow perch (Hgfish) decreased in two of four lakes (mean decreases of 46.5% and 34.5%, respectively, between 2001 and 2012). Counter to decreases in the atmospheric pollutants, MeHgaq increased by 85% in a third lake, whereas Hgfish increased by 80%. The fourth lake had two disturbances in its watershed during the study period (forest fire; changes in shoreline inundation due to beaver activity); this lake lacked overall trends in MeHgaq and Hgfish. The diverging responses among the study lakes exemplify the complexity of ecosystem responses to decreased loads of atmospheric pollutants.

Transient Treg-cell depletion in adult mice results in persistent self-reactive CD4(+) T-cell responses.  

PubMed

Depletion of Foxp3(+) CD4(+) regulatory T cells (Treg) in adults results in chronic inflammation and autoimmune disease. However, the impact of transient Treg-cell depletion on self-reactive responses is poorly defined. Here, we studied the effect of transient depletion of Treg cells on CD4(+) T-cell responses to endogenous self-antigens. Short-term ablation of Treg cells in mice resulted in rapid activation of CD4(+) T cells, increased percentage of IFN-?(+) and Th17 cells in lymphoid organs, and development of autoimmune gastritis. To track self-reactive responses, we analyzed the activation of naïve gastric-specific CD4(+) T cells. There was a dramatic increase in proliferation and acquisition of effector function of gastric-specific T cells in the stomach draining LNs of Treg-cell-depleted mice, compared with untreated mice, either during Treg-cell depletion or after Treg-cell reconstitution. Moreover, the hyperproliferation of gastric-specific T cells in the Treg-cell-ablated mice was predominantly antigen-dependent. Transient depletion of Treg cells resulted in a shift in the ratio of peripheral:thymic Treg cells in the reemerged Treg-cell population, indicating an altered composition of Treg cells. These findings indicate that transient Treg-cell depletion results in ongoing antigen-driven self-reactive T-cell responses and emphasize the continual requirement for an intact Treg-cell population.

Pain and Functional Impairment 1 Year After Inguinal Herniorrhaphy: A Nationwide Questionnaire Study  

PubMed Central

Objective To determine the incidence of groin pain 1 year after inguinal herniorrhaphy and to assess the influence of chronic groin pain on function. Summary Background Data The reported incidence of chronic pain after inguinal herniorrhaphy varies from 0% to 37%. No cross-sectional cohort studies with high follow-up rates have addressed this problem, and there is a lack of assessment of the functional consequences of chronic groin pain after herniorrhaphy. Methods Two sets of self-administered questionnaires were mailed 1 year after surgery. The first established the incidence of chronic groin pain. The second characterized the pain and the effect of the pain on the function of those reporting pain. The study population comprised patients older than age 18 years registered in the Danish Hernia Database who underwent surgery between February 1, 1998, and March 31, 1998. Results The response rate to the first questionnaire was 80.8%. Pain in the groin area was reported by 28.7%, and 11.0% reported that pain was interfering with work or leisure activity. Older patients had a lower incidence of pain. There were no differences in the incidence of pain with regard to the different types of hernia, the different types of surgical repairs, or the different types of anesthesia. The second questionnaire was returned by 83%. Of these, 46 (4%) reported constant pain. The intensity of pain while at rest was moderate or severe in 40 (3%); with physical activity, pain was moderate or severe in 91 (8%). Impairment of specific daily activities as a result of pain was reported by 194 (16.6%). Pain characteristics were predominantly sensory, with a low use of affective terms. Conclusion One year after inguinal hernia repair, pain is common (28.7%) and is associated with functional impairment in more than half of those with pain. These factors should be addressed when discussing the need for surgical intervention for an inguinal hernia. PMID:11141218

Does one result trump all others? A response to Magurran, Irving and Henderson  

PubMed Central

Magurran, Irving and Henderson (1997) have reported that a population of European minnows, Phoxinus phoxinus, did not show an obvious behavioural fright reaction when they were presented with conspecific skin extract in a wild situation. Fish from the same population show a strong response when tested in aquaria. From these data the authors conclude that the fright reaction may be contingent on such factors as assessed risk and hunger. From this reasonable hypothesis they progress to the assertion that the Schreckstoff of ostariophysan fishes should not be considered an alarm pheromone. Much of their paper is devoted to arguments supporting their hypothesis that Schreckstoff cannot operate as an alarm pheromone. I argue that it is appropriate and adaptive to respond to alarm signals in a contingent manner, and attempt to answer the various arguments regarding the validity of terming Schreckstoff an alarm pheromone.

Cross-cultural adaptation and validation of the VISA-A questionnaire for German-speaking Achilles tendinopathy patients  

Microsoft Academic Search

BACKGROUND: Achilles tendinopathy is the predominant overuse injury in runners. To further investigate this overload injury in transverse and longitudinal studies a valid, responsive and reliable outcome measure is demanded. Most questionnaires have been developed for English-speaking populations. This is also true for the VISA-A score, so far representing the only valid, reliable, and disease specific questionnaire for Achilles tendinopathy.

International Physical Activity Questionnaire (IPAQ) and New Zealand Physical Activity Questionnaire (NZPAQ): A doubly labelled water validation  

PubMed Central

Background Accurate measurement of physical activity is a pre-requisite for monitoring population health and for evaluating effective interventions. The International Physical Activity Questionnaire (IPAQ) is used as a comparable and standardised self-report measure of habitual physical activity of populations from different countries and socio-cultural contexts. The IPAQ has been modified to produce a New Zealand physical activity questionnaire (NZPAQ). The aim of this study was to validate the IPAQ and NZPAQ against doubly labelled water (DLW). Method: Total energy expenditure (TEE) was measured over a 15-day period using DLW. Activity-related energy expenditure (AEE) was estimated by subtracting the energy expenditure from resting metabolic rate and thermic effect of feeding from TEE. The IPAQ (long form) and NZPAQ (short form) were completed at the end of each 7-day period. Activity-related energy expenditure (IPAQAEE and NZPAQAEE) was calculated from each questionnaire and compared to DLWAEE. Results Thirty six adults aged 18 to 56 years (56% female) completed all measurements. Compared to DLWAEE, IPAQAEE and NZPAQAEE on average underestimated energy expenditure by 27% and 59%, respectively. There was good agreement between DLWAEE and both IPAQAEE and NZPAQAEE at lower levels of physical activity. However there was marked underestimation of questionnaire-derived energy expenditure at higher levels of activity. Conclusion Both the IPAQ and NZPAQ instruments have a demonstrated systematic bias toward underestimation of physical activity-related energy expenditure at higher levels of physical activity compared to DLW. Appropriate calibration factors could be used to correct for measurement error in physical activity questionnaires and hence improve estimation of AEE. PMID:18053188

The pornography craving questionnaire: psychometric properties.  

PubMed

Despite the prevalence of pornography use, and recent conceptualization of problematic use as an addiction, we could find no published scale to measure craving for pornography. Therefore, we conducted three studies employing young male pornography users to develop and evaluate such a questionnaire. In Study 1, we had participants rate their agreement with 20 potential craving items after reading a control script or a script designed to induce craving to watch pornography. We dropped eight items because of low endorsement. In Study 2, we revised both the questionnaire and cue exposure stimuli and then evaluated several psychometric properties of the modified questionnaire. Item loadings from a principal components analysis, a high internal consistency reliability coefficient, and a moderate mean inter-item correlation supported interpreting the 12 revised items as a single scale. Correlations of craving scores with preoccupation with pornography, sexual history, compulsive internet use, and sensation seeking provided support for convergent validity, criterion validity, and discriminant validity, respectively. The enhanced imagery script did not impact reported craving; however, more frequent users of pornography reported higher craving than less frequent users regardless of script condition. In Study 3, craving scores demonstrated good one-week test-retest reliability and predicted the number of times participants used pornography during the following week. This questionnaire could be applied in clinical settings to plan and evaluate therapy for problematic users of pornography and as a research tool to assess the prevalence and contextual triggers of craving among different types of pornography users.

Transplant physicians' perceptions of cord blood transplantation in Korea: a questionnaire survey  

PubMed Central

Background Although bone marrow (BM) or mobilized peripheral blood (PB) is frequently used as the source of hematopoietic stem cells, hematopoietic stem cell transplantation (HSCT) using cord blood (CB) is gradually gaining popularity in many countries. However, BM or PB is still preferred over CB in Korea. Therefore, we tried to assess the awareness of CB transplantation (CBT) among domestic HSCT physicians and develop strategies for boosting its utilization by administering questionnaires to some of these physicians. Methods A direct questionnaire survey was conducted using the "Audience Response System" among 301 members who attended the annual meeting of the Korean Society of Blood and Marrow Transplantation. The data were analyzed for only 67 board certified physicians who were directly involved in HSCT activities. Results The poor outcomes resulting from insufficient experience in CBT was designated by the physicians as the main reason for the low domestic implementation of HSCT using CB. Other reasons identified in the survey were distrust in the quality and management of domestic CB and the high cost of obtaining CB. Conclusion Increasing the use of donated CB would foremost require increasing the inventory of donated CB containing a sufficient cell number for CBT and securing structured quality control of the CB banks. In addition, it would be necessary to minimize CB supply costs and continue to provide academic data, including CBT guidelines, so that clinicians could perform CBT with more confidence.

Non-response of cortisol during stressful exposure therapy in patients with obsessive-compulsive disorder--preliminary results.  

PubMed

Exposure with response prevention (ERP) is an established treatment for patients with obsessive-compulsive disorder (OCD) and also an interesting model to characterize neuroendocrine response to psychological stress. However, so far few studies have assessed hypothalamic-pituitary-adrenocortical (HPA) function during ERP and results are inconsistent. In 15 patients with OCD we repeatedly measured salivary cortisol and subjective units of distress (SUD) on two consecutive afternoons. The first day served as a comparison condition; on the second day the very first session of ERP took place. While SUD were significantly increased during ERP versus the comparison day, salivary cortisol was statistically indistinguishable between ERP and comparison conditions before, during and after ERP. Thus, despite considerable psychological stress no increase of cortisol was observed. This response pattern to ERP in OCD patients needs further research. PMID:22578822

The ChromaGen contact lens system: colour vision test results and subjective responses.  

PubMed

The ChromaGen lens system is designed to enhance colour perception in colour vision deficiency (CVD). To investigate its efficacy, 14 CVD subjects were prescribed ChromaGen contact lenses. Colour vision tests (Ishihara, Farnsworth Munsell D-15, Farnsworth Lantern) were administered at baseline, lens dispensing, and after a 2-week lens-wearing trial during which subjective responses were recorded daily using visual analogue scales. ChromaGen lenses significantly reduced ishihara error rates (p < 0.001; ANOVA), particularly for deutan subjects. There was also a significant reduction in errors (p < 0.005) on the D-15 test. Conversely, lens wear had no significant effect on Farnsworth Lantern test performance. Subjectively, subjects reported enhanced colour perception, but poor vision in dim light. Judgement of distance and motion were only slightly affected. We conclude that ChromaGen lenses may enhance subjective colour experience and assist in certain colour-related tasks, but are not indicated as an aid for CVD in occupations with colour vision-related restrictions.

Response of lead-acid batteries to chopper-controlled discharge: Preliminary results  

NASA Technical Reports Server (NTRS)

The preliminary results of simulated electric vehicle, chopper, speed controller discharge of a battery show energy output losses up to 25 percent compared to constant current discharges at the same average discharge current of 100 amperes. These energy losses are manifested as temperature rises during discharge, amounting to a two-fold increase for a 400-ampere pulse compared to the constant current case. Because of the potentially large energy inefficiency, the results suggest that electric vehicle battery/speed controller interaction must be carefully considered in vehicle design.

This study reports on the development of the Multicultural Personality Questionnaire-Short Form among 511 participants. Using a split-sample scale validation design, Study 1 (N = 260) employed a principal component analysis and rigorous item selection criteria to extract a 40-item short form (MPQ-SF) from the original 91-item Multicultural Personality Questionnaire (MPQ; van der Zee & van Oudenhoven, 2000, 2001). In Study 2 (N = 251), the MPQ-SF was subjected to confirmatory factor analysis and resulted in a reasonably good fit to the data (comparative fit index = .94; root mean squared error of approximation = .066). Satisfactory coefficient alphas and high correlations with the original scales were found. Moreover, relationships with related scales were largely in the predicted direction. Specific directions for follow-up research are posited. PMID:22966866

Objective: To establish norms for sexual functioning questionnaire (SFQ) in Indian population. Materials and Methods: 100 male subjects, diagnosed with depressive disorder and currently in a state of clinical remission for a period of at least 4 weeks were evaluated on SFQ and Arizona Sexual Experience Questionnaire (ASEX). Result: By using receiver operating characteristics (ROC) curves a score of 14 was considered to be a cutoff for sexual dysfunction as per SFQ. This cutoff yielded a sensitivity of 91.7% and specificity of 86.4% for the detection of sexual dysfunction. The PPV of the instrument at this cutoff was 87%. Conclusion: A cutoff of 14 should be used to define sexual dysfunction as per SFQ. PMID:25336774

Late radiation responses in man: Current evaluation from results from Hiroshima and Nagasaki  

NASA Astrophysics Data System (ADS)

Among the late effects of exposure to the atomic bombings of Hiroshima and Nagasaki, none looms larger than radiation related malignancies. Indeed, the late effects of A-bomb radiation on mortality appear to be limited to an increase in malignant tumors. At present, it can be shown that cancers of the breast, colon, esophagus, lungs, stomach, thyroid, and urinary tract as well as leukemia and multiple myeloma increase in frequency with an increase in exposure. No significant relationship to radiation can as yet be established for malignant lymphoma, nor cancers of the rectum, pancreas or uterus. Radiation induced malignancies other than leukemia seem to develop proportionally to the natural cancer rate for the attained age. For specific age-at-death intervals, both relative and absolute risks tend to be higher for those of younger age at the time of bombing. Other late effects include radiation-related lenticular opacities, disturbances of growth among those survivors still growing at the time of exposure, and mental retardation and small head sizes among the in utero exposed. Chromosomal abnormalities too are more frequently encountered in the peripheral leucocytes of survivors, and this increase is functionally related to their exposure. Some uncertainty continues to surround both the quantity and quality of the radiation released by these two nuclear devices, particularly the Hiroshima bomb. A recent reassessment suggests that the gamma radiation estimates which have been used in the past may be too low at some distances and the neutron radiation estimates too high at all distances; moreover, the energies of the neutrons released now appear ``softer'' than previously conjectured. These uncertainties not sufficiently large, however, to compromise the reality of the increased frequency of malignancy, but make estimates of the dose response, particularly in terms of gamma and neutron exposures, tentative.

Nonresponse patterns in the Federal Waterfowl Hunter Questionnaire Survey  

USGS Publications Warehouse

I analyzed data from the 1984 and 1986 Federal Waterfowl Hunter Questionnaire Survey (WHQS) to estimate the rate of return of name and address contact cards, to evaluate the efficiency of the Survey's stratification scheme, and to investigate potential sources of bias due to nonresponse at the contact card and questionnaire stages of the Survey. Median response at the contact card stage was 0.200 in 1984 and 0.208 in 1986, but was lower than 0.100 for many sample post offices. Large portions of the intended sample contributed little to the final estimates in the Survey. Differences in response characteristics between post office size strata were detected, but size strata were confounded with contact card return rates; differences among geographic zones within states were more pronounced. Large biases in harvest and hunter activity due to nonresponse were not found; however, consistent smaller magnitude biases were found. Bias in estimates of the proportion of active hunters was the most pronounced effect of nonresponse. All of the sources of bias detected would produce overestimates of harvest and activity. Redesigning the WHQS, including use of a complete list of waterfowl hunters and resampling nonrespondents, would be needed to reduce nonresponse bias.

Earth is speaking: listen her! On-line questionnaire about anomalous geological and biological phenomena  

NASA Astrophysics Data System (ADS)

Earthquakes can be associated with non-seismic phenomena which may manifest many weeks before and after the main shock. These phenomena are characterized by ground fractures and soil liquefactions at surface often coupled with degassing events, chemical alterations of water and soils, changes in temperature and/or waters level in the epicentral area. Further manifestations include radio disturbances and light emissions. On the other hand, anomalous behavior of animals has been reported to occur before environmental changes. The co-occurrence of several phenomena may be considered as a signal of subsurface changes, and their analysis may be used as possible forecast indicators for seismic events, landslides, damages in infrastructure (e.g., dam) and groundwaters contamination. In order to obtain an accurate statistical analysis of these factors, a pre-crisis large database over a prolonged period of time is a pre-requisite. To this end, we elaborated a questionnaire for the population to pick up signs about anomalous phenomena like as: animal behavior, geological manifestations, effect on vegetation, degassing, changes on aquifers, wells and springs. After the January 25, 2013, mainshock (ML 4.8) in the Garfagnana seismic district, the Bagni di Lucca Municipality was selected as pilot site for testing this questionnaire. The complexity, variety and extension of this territory (165 kmq) sound suitable for this project. Bagni di Lucca is located in the southern border of the Garfagnana seismogenic source, characterized by the carbonate Mesozoic sequences and the Tertiary terrigenous sedimentary deposits of the Tuscan Nappe. The questionnaire was published on Bagni di Lucca web site (https://docs.google.com/file/d/0Bzw3vOYX47XoTGltTVJRbkJuajA/edit) in collaboration with Municipal Commitee, Local Civil Protection and Local Red Cross, and sent by ordinary mail to the citizenry. It is possible to answer to the questionnaire, also anonymously, direct on line (https://docs.google.com/forms/d/1LVNVQFzMoJJfNxp2eSPAc4pcwj4_qIdbAnvbCWGyXy8/viewform?pli=1), calling the Local Civil Protection or Local Red Cross, and by mail. In a second time, an application for Smartphone and Tablets will be developed to allow a faster reply. The questionnaire, constituted by eleven questions and organized in four macro-themes (i.e. animal behavior, geological factors, vegetation anomalies and hydrogeological changes) has been published in June 2013 and will remain on-line for several years. Indeed, the social perception is not fully trustworthy during and soon after an earthquake. So far this is the first attempt to acquire data during quiescent times for comparison with post-seismic ones. This approach may provide clues to identify phenomena properly linked to the event. This questionnaire can be a useful tool to educate population not only about earthquake precursors but also to recognize the "Earth language". Submitted testimonies will be statistically analyzed evidencing the specific responses to the different phenomena in space and time. On the basis of obtained results the questionnaire project could be extended to national level.

NASA Astrophysics Data System (ADS)

Permafrost or perennially frozen ground is an important part of the terrestrial cryosphere; roughly one quarter of Earth's land surface is underlain by permafrost. As it is a thermal phenomenon, its characteristics are highly dependent on climatic factors. The impact of the currently observed warming, which is projected to persist during the coming decades due to anthropogenic CO2 input, certainly has effects for the vast permafrost areas of the high northern latitudes. The quantification of these effects, however, is scientifically still an open question. This is partly due to the complexity of the system, where several feedbacks are interacting between land and atmosphere, sometimes counterbalancing each other. Moreover, until recently, many global circulation models (GCMs) lacked the sufficient representation of permafrost physics in their land surface schemes. In order to assess the response of permafrost to projected climate change for the 21st century, the land surface scheme of the Max-Planck-Institute for Meteorology, JSBACH, has recently been equipped with the important physical processes for permafrost studies, and was driven globally with bias corrected climate data, thereby spanning a period from 1850 until 2100. The applied land surface scheme JSBACH now considers the effects of freezing and thawing of soil water for both energy and water cycles, thermal properties depending on soil water and ice contents, and soil moisture movement being influenced by the presence of soil ice. To address the uncertainty range arising through different greenhouse gas concentrations as well as through different climate realisations when using various climate models, combinations of two Representative Concentration Pathways (RCPs) and two GCMs were used as driving data. In order to focus only on the climatic impact on permafrost, effects due to feedbacks between climate and permafrost (namely via carbon fluxes between land and atmosphere) are excluded in the experiments. Differences between future time slices and today's climate are analysed. The effect in relevant variables, such as permafrost extent, depth of the Active Layer, ground temperature, and amount of soil carbon, is investigated. The experiments (as well as the development of JSBACH with respect to permafrost soil physics) are part of the European project PAGE21, where a focus is set on interactions between the changing climate and its impact on permafrost, especially for the 21st century.

Measurement properties of the Wheelchair Skills Test - Questionnaire for powered wheelchair users.  

PubMed

Abstract Purpose: To evaluate the test-retest reliability, concurrent validity and responsiveness of the Wheelchair Skills Test - Questionnaire (WST-Q) Version 4.1 for powered wheelchair users. Methods: A volunteer sample of 72 community-dwelling, experienced powered wheelchair users, ranging in age from 50 to 77 years, participated in this study. Participants completed measures at baseline and 1 month later. Results: Mean?±?standard deviation total percentage WST-Q scores at baseline and 1 month were 83.7%?±?10.9 and 86.3%?±?10.0 respectively. Cronbach's alpha was 0.90 and the 1 month test-retest intraclass correlation coefficient (ICC1,1) was 0.78 (confidence interval: 0.68-0.86). There were no floor or ceiling effects. Percentages of agreement between baseline and 1 month for individual skills ranged from 72.2% to 100%. The correlations between the WST-Q and the objective Wheelchair Skills Test (WST), WheelCon and Life Space Assessment were r?=?0.65, r?=?0.47 and r?=?0.47 respectively. The standard error of measurement (SEM) and smallest real difference (SRD) were 5.0 and 6.2 respectively. Conclusion: The WST-Q 4.1 has high internal consistency, strong test-retest reliability and strong support for concurrent validity and responsiveness. Implications for Rehabilitation: There is evidence of reliability, validity and responsiveness of the Wheelchair Skills Test - Questionnaire (WST-Q) among experienced older adult powered wheelchair users. The WST-Q can be used to measure powered wheelchair skills, guide intervention and measure change over time. PMID:25411057

Response of benthic insect species to changes in stream velocity resulting from stripmining disturbance  

SciTech Connect

Increased stream velocity resulting from increased runoff may cause considerable alterations in benthic communities. Stream velocity in disturbed watersheds can exceed tolerance limits of even the most resistant species. Increased velocities may also adversely impact benthic communities by increasing bedload movement, thus destroying habitats or physically abrading individuals. Studies are underway to document bedload movement and effects on benthic communities in mining disturbed streams. Additional studies are being initiated to determine if there are additive effects from the combination of increased stream velocity and sediment movement.

Reliability of a self-reported health questionnaire in a periodontal disease study.  

PubMed

This study assesses the reliability of a self-reported health questionnaire completed by 413 subjects aged 25-74 yr in the Erie County Periodontal Disease (ECPD) Study. Specific questions on general and oral health conditions were completed by each subject during a first visit and at a follow-up examination 2 yr later, and the two compared. Results showed that the overall measure of agreement between the two visits is substantial (average kappa, kappa = 0.80). Variation by gender and age were minimal. Questions regarding allergy to medications, oral treatment, reason for tooth extraction, health symptoms and history of systemic diseases exhibited high levels of agreement (kappa ranged from 0.71-0.90). Information on vitamin and mineral intake yielded kappa = 0.63. Oral conditions scored the lowest but were still acceptable (kappa = 0.57). These findings indicate that there were no significant discrepancies in self-reported responses to the health questionnaire used in the ECPD Study. Although the information provided by the subject may not be as accurate as compared to laboratory testing, it is nevertheless a reliable source of information which can be utilized cost-effectively in research studies.

Views of senior UK doctors about working in medicine: questionnaire survey  

PubMed Central

Summary Objectives We surveyed the UK medical qualifiers of 1993. We asked closed questions about their careers; and invited them to give us comments, if they wished, about any aspect of their work. Our aim in this paper is to report on the topics that this senior cohort of UK-trained doctors who work in UK medicine raised with us. Design Questionnaire survey Participants 3479 contactable UK-trained medical graduates of 1993. Setting UK. Main outcome measures Comments made by doctors about their work, and their views about medical careers and training in the UK. Method Postal and email questionnaires. Results Response rate was 72% (2507); 2252 were working in UK medicine, 816 (36%) of whom provided comments. Positive comments outweighed negative in the areas of their own job satisfaction and satisfaction with their training. However, 23% of doctors who commented expressed dissatisfaction with aspects of junior doctors’ training, the impact of working time regulations, and with the requirement for doctors to make earlier career decisions than in the past about their choice of specialty. Some doctors were concerned about government health service policy; others were dissatisfied with the availability of family-friendly/part-time work, and we are concerned about attitudes to gender and work-life balance. Conclusions Though satisfied with their own training and their current position, many senior doctors felt that changes to working hours and postgraduate training had reduced the level of experience gained by newer graduates. They were also concerned about government policy interventions. PMID:25408920

Psychometric properties of the Questionnaire for Secondary Traumatization  

PubMed Central

Background During the past several years, there has been a growing interest in the negative effects that providing therapy may have on therapists. Of special interest is a phenomenon called secondary traumatization, which can arise while working with traumatized clients. To develop a simple screening tool for secondary traumatization, a quantitative assessment instrument was constructed using a data-driven approach based on qualitative interviews with affected trauma therapists as well as experienced supervisors in trauma therapy. Objective The aim of the current study was to analyze the psychometric properties of the newly developed Questionnaire for Secondary Traumatization (FST) acute and lifetime version and to determine the most appropriate scoring procedure. Method To this end, three independent samples of psychotherapists (n=371), trauma therapists in training (n=80), and refugee counselors (n=197) filled out an online questionnaire battery. Data structure was analyzed using factor analyses, cluster analyses, and reliability analyses. Results Factor analyses yielded a six-factor structure for both the acute and the lifetime version with only a small number of items loading on differing factors. Cluster analyses suggested a single scale structure of the questionnaire. The FST total score showed good internal consistencies across all three samples, while internal consistency of the six extracted factors was mixed. Conclusion With the FST, a reliable screening instrument for acute and lifetime secondary traumatization is now available which is free of charge and yields a sum score for quick evaluation. The six-factor structure needs to be verified with confirmatory factor analyses. PMID:24427450

Development and Validation of the Pregnancy and Infant Orientation Questionnaire  

PubMed Central

The purpose of this current study was the construction, scaling, and scale validation of a self-report questionnaire assessing biographical information and motivation for pregnancy and infant care in men and women with disorders of sex development or other gender variations of potential clinical relevance. The overall design of the questionnaire and the initial item pool were derived from related clinical and research experience. Collection of pilot data and, where appropriate, scale construction (via principal components analyses) were based on Canadian convenience samples of heterosexual (HET) and non-HET men and women (N=414). A sample of gender-dysphoric (GDYS) men and women (n=45) was added for validity analysis. Validation of the resulting scales was based on the demonstration of expected scale differences between HET men and women, as well as between HET, non-HET, and GDYS men and between HET, non-HET, and GDYS women, and was successful with one exception. This study concludes that this new questionnaire, in addition to its descriptive sections, provides several distinct scales related to desires for child bearing and child rearing and has good psychometric properties.

Validation of an asthma questionnaire for use in healthcare workers  

PubMed Central

Background Previous studies have described increased occurrence of asthma among healthcare workers, but to our knowledge there are no validated survey questionnaires with which to study this occupational group. Aims To develop, validate, and refine a new survey instrument on asthma for use in epidemiological studies of healthcare workers. Methods An initial draft questionnaire, designed by a multidisciplinary team, used previously validated questions where possible; the occupational exposure section was developed by updating health services specific chemical lists through hospital walk?through surveys and review of material safety data sheets. A cross?sectional validation study was conducted in 118 non?smoking subjects, who also underwent bronchial challenge testing, an interview with an industrial hygienist, and measurement of specific IgE antibodies to common aeroallergens. Results The final version consisted of 43 main questions in four sections. Time to completion of the questionnaire ranged from 13 to 25 minutes. Test–retest reliability of asthma and allergy items ranged from 75% to 94%, and internal consistency for these items was excellent (Cronbach's ? ? 0.86). Against methacholine challenge, an eight item combination of asthma related symptoms had a sensitivity of 71% and specificity of 70%; against a physician diagnosis of asthma, this same combination showed a sensitivity of 79% and specificity of 98%. Agreement between self?reported exposures and industrial hygienist review was similar to previous studies and only moderate, indicating the need to incorporate more reliable methods of exposure assessment. Against the aerollergen panel, the best combinations of sensitivity and specificity were obtained for a history of allergies to dust, dust mite, and animals. Conclusions Initial evaluation of this new questionnaire indicates good validity and reliability, and further field testing and cross?validation in a larger healthcare worker population is in progress. The need for development of more reliable occupational exposure assessment methods that go beyond self?report is underscored. PMID:16497858

Small business needs assessment: a comparison of dental educators' responses with SBDC survey results.  

PubMed

A primary focus of dental education is to teach students the knowledge, skills, and values essential for practicing dentistry. However, the preparation of dentists to manage a business is frequently cited as inadequate. A survey was prepared to assess teachers' opinions of business instructional topics: challenges; desired training; employee benefits; learning resources; importance of business topics; and appropriateness of time allocations. The purpose of this project is to compare opinions of teachers of dental practice management with key management aspects reported for service businesses by the Small Business Development Center (SBDC). Practice management teachers from forty-eight (89 percent) schools responded to the survey. They indicated that several challenges confronting dentists are similar to other service businesses. Dentists, however, rank customer relations appreciably higher. In order of importance of teaching topics, the practice management teachers rank ethics and personnel management as a high priority and planning as a low priority. Awareness of the similarities and differences in the perceptions of practice management teachers and businesspeople may result in instructional improvements. PMID:11569602

Frequency—response analysis of central vestibular unit activity resulting from rotational stimulation of the semicircular canals  

PubMed Central

1. The neural response of semicircular canal-dependent units in the vestibular nuclei of cats has been examined over a frequency range of sinusoidal rotation extending from 0·004 to 0·9 Hz. 2. Frequency—response analysis indicates that, over the range examined, the information contained in the neural signal received by the brain stem was similar to that expected from the mechanical end-organ. 3. Over the experimental frequency range, the relation between neural response and mechanical stimulus was found to be dominated by a single time constant of about 4 sec, such that two response regions can be defined above and below a stimulus frequency of ¼ rad/sec (? ? Hz). 4. Above this frequency the information content of the neural signal tends towards that of angular velocity and below that frequency it tends towards that of angular acceleration. 5. It is inferred (a) that the so-called `long' time constant of the cat's horizontal canal is about 4 sec and (b) that during most normal head movements containing frequencies below about 1 Hz the informational mode of neural signals generated in the canal and received in the brain stem probably tends towards that of head angular velocity. 6. This seems appropriate for the generation of vestibulo-ocular reflex compensation for head movement and for reflex damping (negative velocity feed-back) of unintended head and body movements. 7. The average neural gain of central unit responses is estimated at 1264 action potentials/sec, per degree of cupular deflexion. This high value reflects the very small angles of cupular deflexion assessed on the basis of physical characteristics of the canal. 8. The results permit a rough estimate of the elastic restoring coefficient of the cupula in the horizontal canal as 2·05 × 10-3 dyne. cm. PMID:4333863

Long-term changes in cognitive bias and coping response as a result of chronic unpredictable stress during adolescence  

PubMed Central

Animals that experience adverse events in early life often have life-long changes to their physiology and behavior. Long-term effects of stress during early life have been studied extensively, but less attention has been given to the consequences of negative experiences solely during the adolescent phase. Adolescence is a particularly sensitive period of life when regulation of the glucocorticoid “stress” hormone response matures and specific regions in the brain undergo considerable change. Aversive experiences during this time might, therefore, be expected to generate long-term consequences for the adult phenotype. Here we investigated the long-term effects of exposure to chronic unpredictable stress during adolescence on adult decision-making, coping response, cognitive bias, and exploratory behavior in rats. Rats exposed to chronic unpredictable stress (e.g., isolation, crowding, cage tilt) were compared to control animals that were maintained in standard, predictable conditions throughout development. Unpredictable stress during adolescence resulted in a suite of long-term behavioral and cognitive changes including a negative cognitive bias [F(1, 12) = 5.000, P < 0.05], altered coping response [T(1, 14) = 2.216, P = 0.04], and accelerated decision-making [T(1, 14) = 3.245, P = 0.01]. Exposure to chronic stress during adolescence also caused a short-term increase in boldness behaviors; in a novel object test 15 days after the last stressor, animals exposed to chronic unpredictable stress had decreased latencies to leave a familiar shelter and approach a novel object [T(1, 14) = 2.240, P = 0.04; T(1, 14) = 2.419, P = 0.03, respectively]. The results showed that stress during adolescence has long-term impacts on behavior and cognition that affect the interpretation of ambiguous stimuli, behavioral response to adverse events, and how animals make decisions.

Readability of patient-reported outcome questionnaires for use with persons with swallowing disorders.  

PubMed

The purposes of this study were to examine the readability of published patient-related outcome (PRO) questionnaires for persons with swallowing problems, and to compare the readability results to existing data about average reading levels of English-speaking adults living in the United States. A search was conducted to identify published PRO questionnaires related to swallowing problems that traditionally are completed by patients in a self-administered format. Reading grade levels were analyzed separately for four different swallowing-related PRO questionnaires using the Flesch Reading Ease, FOG, and FORCAST formulas as computed by a readability calculations software package. Descriptive statistics were also computed across the questionnaires. The results of this study demonstrate that all four PRO questionnaires exceeded the fifth- to sixth-grade reading levels recommended by health literacy experts regardless of the formula applied. In the demand for standardization of swallowing-related quality-of-life assessment tools, developers should consider readability as another testable construct, since poor readability may affect validity, reliability, and sensitivity. The swallowing clinician should consider the average reading level needed to understand a particular PRO questionnaire when administering it to a patient or his or her proxy. Developers of PRO questionnaires should consider the reading level of respondents and include information about this when reporting psychometric data. PMID:22038114

Measuring determinants of implementation behavior: psychometric properties of a questionnaire based on the theoretical domains framework  

PubMed Central

Background To be able to design effective strategies to improve healthcare professionals’ implementation behaviors, a valid and reliable questionnaire is needed to assess potential implementation determinants. The present study describes the development of the Determinants of Implementation Behavior Questionnaire (DIBQ) and investigates the reliability and validity of this Theoretical Domains Framework (TDF)-based questionnaire. Methods The DIBQ was developed to measure the potential behavioral determinants of the 12-domain version of the TDF (Michie et al., 2005). We identified existing questionnaires including items assessing constructs within TDF domains and developed new items where needed. Confirmatory factor analysis was used to examine whether the predefined structure of the TDF-based questionnaire was supported by the data. Cronbach’s alpha was calculated to assess internal consistency reliability of the questionnaire, and domains’ discriminant validity was investigated. Results We developed an initial questionnaire containing 100 items assessing 12 domains. Results obtained from confirmatory factor analysis and Cronbach’s alpha resulted in the final questionnaire consisting of 93 items assessing 18 domains, explaining 63.3% of the variance, and internal consistency reliability values ranging from .68 to .93. Domains demonstrated good discriminant validity, although the domains ‘Knowledge’ and ‘Skills’ and the domains ‘Skills’ and ‘Social/professional role and identity’ were highly correlated. Conclusions We have developed a valid and reliable questionnaire that can be used to assess potential determinants of healthcare professional implementation behavior following the theoretical domains of the TDF. The DIBQ can be used by researchers and practitioners who are interested in identifying determinants of implementation behaviors in order to be able to develop effective strategies to improve healthcare professionals’ implementation behaviors. Furthermore, the findings provide a novel validation of the TDF and indicate that the domain ‘Environmental context and resources’ might be divided into several environment-related domains.

WHO quality of life-BREF 26 questionnaire: reliability and validity of the Persian version and compare it with Iranian diabetics quality of life questionnaire in diabetic patients.  

PubMed

There are several tools for the assessment of quality of life (QOL) in diabetes mellitus. In the current research, two standard questionnaires for evaluating of QOL were selected. First one was a questionnaire from the World Health Organization quality of life (WHOQOL-BREF 26) and the second one, The Iranian diabetics quality of life (IRDQOL). The first aim of this study was to reliability and validity of the Persian Version of WHOQOL-BREF 26. The second aims compare it with IRDQOL questionnaire in diabetic patients. A random sample of Iranian adult outpatient diabetics (n=387) was selected and they completed the WHOQOL and IRDQOL assessment instruments. In addition HbA1c was measured in these patients by calorimetric method. Data analysis was carried out by the use of T-test, Spearman correlation coefficient, Pearson's correlation coefficient. Data analysis based on Pearson correlations in the two questionnaires showed all subscales and total QOL have highly acceptable test-retest reliability. Comparison of total QOL and similar domains in the two questionnaires showed physical domain score in IRDQOL was lower than in WHOQOL and it was significant (P<.0001). Total QOL is more highly correlated with social domain and environmental domain in IRDQOL and WHOQOL, respectively. In IRDQOL, spiritual domain is not correlated with physical domain. Calculated parameters of reliability in the questionnaires indicated that stability present promising results in total QOL. In this study, WHOQOL domains have a logical relationship between glycemic control and QOL, but this logical relationship cannot be found in IRDQOL questionnaire. In IRDQOL spiritual domain is a very unreliable domain. We recommend more questions to be added spiritual domain in IRDQOL questionnaire and also distribution of items to be some how equal in four domains. By these, it may help to find some rational relations between afore-mentioned domains and glycemic control. PMID:21481660

Electronic pelvic floor assessment questionnaire: a systematic review.  

PubMed

Quality of life can be seriously affected by pelvic floor disorders and a range of other coexisting symptoms. The electronic patient assessment questionnaire (ePAQ®) is a validated tool that can be used for the assessment of pelvic floor disorders. The authors aimed to systematically review all the studies that had used ePAQ for assessment of pelvic-floor-related quality of life. The delivery of evidence-based care is paramount and dependent on a precise, detailed clinical history. A pelvic floor questionnaire is an effective way of assessing the effect of pelvic floor dysfunction on quality of life. A thorough literature search was conducted in November 2013 using various search engines. A total of 15 articles were found. Four of these articles were excluded as ePAQ had not been used and the remaining 11 articles summarised. The main themes drawn from the studies were: screening and diagnostic uses, treatment prioritisation, treatment response and miscellaneous/qualitative data. The findings illustrate that the pelvic floor assessment version of ePAQ is a useful tool in assessing patients before and after receiving pelvic floor treatment. PMID:25303001

A self-report comorbidity questionnaire for haemodialysis patients  

PubMed Central

Background Patients with end-stage renal disease (ESRD) have multiple comorbid conditions. Obtaining comorbidity data from medical records is cumbersome. A self-report comorbidity questionnaire is a useful alternative. Our aim in this study was to examine the predictive value of a self-report comorbidity questionnaire in terms of survival in ESRD patients. Methods We studied a prospective cross-sectional cohort of 282 haemodialysis (HD) patients in a single centre. Participants were administered the self-report questionnaire during an HD session. Information on their comorbidities was subsequently obtained from an examination of the patient’s medical records. Levels of agreement between parameters derived from the questionnaire, and from the medical records, were examined. Participants were followed-up for 18 months to collect survival data. The influence on survival of comorbidity scores derived from the self-report data (the Composite Self-report Comorbidity Score [CSCS]) and from medical records data - the Charlson Comorbidity Index [CCI] were compared. Results The level of agreement between the self-report items and those obtained from medical records was almost perfect with respect the presence of diabetes (Kappa score ? 0.97), substantial for heart disease and cancer (? 0.62 and ? 0.72 respectively), moderate for liver disease (? 0.51), only fair for lung disease, arthritis, cerebrovascular disease, and depression (? 0.34, 0.35, 0.34 and 0.29 respectively). The CSCS was strongly predictive of survival in regression models (Nagelkerke R2 value 0.202), with a predictive power similar to that of the CCI (Nagelkerke R2 value 0.211). The influences of these two parameters were additive in the models – suggesting that these parameters make different contributions to the assessment of comorbidity. Conclusion This self-report comorbidity questionnaire is a viable tool to collect comorbidity data and may have a role in the prediction of short-term survival in patients with end-stage renal disease on haemodialysis. Further work is required in this setting to refine the tool and define its role. PMID:25135668

Contributing factors to influenza vaccine uptake in general hospitals: an explorative management questionnaire study from the Netherlands  

PubMed Central

Background The influenza vaccination rate in hospitals among health care workers in Europe remains low. As there is a lack of research about management factors we assessed factors reported by administrators of general hospitals that are associated with the influenza vaccine uptake among health care workers. Methods All 81 general hospitals in the Netherlands were approached to participate in a self-administered questionnaire study. The questionnaire was directed at the hospital administrators. The following factors were addressed: beliefs about the effectiveness of the influenza vaccine, whether the hospital had a written policy on influenza vaccination and how the hospital informed their staff about influenza vaccination. The questionnaire also included questions about mandatory vaccination, whether it was free of charge and how delivered as well as the vaccination campaign costs. The outcome of this one-season survey is the self-reported overall influenza vaccination rate of health care workers. Results In all, 79 of 81 hospitals that were approached were willing to participate and therefore received a questionnaire. Of these, 42 were returned (response rate 52%). Overall influenza vaccination rate among health care workers in our sample was 17.7% (95% confidence interval: 14.6% to 20.8%). Hospitals in which the administrators agreed with positive statements concerning the influenza vaccination had a slightly higher, but non-significant, vaccine uptake. There was a 9% higher vaccine uptake in hospitals that spent more than €1250,- on the vaccination campaign (24.0% versus 15.0%; 95% confidence interval from 0.7% to 17.3%). Conclusions Agreement with positive statements about management factors with regard to influenza vaccination were not associated with the uptake. More economic investments were related with a higher vaccine uptake; the reasons for this should be explored further. PMID:23259743

Evaluation of a Validated Food Frequency Questionnaire for Self-Defined Vegans in the United States  

PubMed Central

This study aimed to develop and validate a de novo food frequency questionnaire for self-defined vegans in the United States. Diet histories from pilot samples of vegans and a modified ‘Block Method’ using seven selected nutrients of concern in vegan diet patterns, were employed to generate the questionnaire food list. Food frequency responses of 100 vegans from 19 different U.S. states were obtained via completed mailed questionnaires and compared to multiple telephone-conducted diet recall interviews. Computerized diet analyses were performed. Correlation coefficients, t-tests, rank, cross-tabulations, and probability tests were used to validate and compare intake estimates and dietary reference intake (DRI) assessment trends between the two methods. A 369-item vegan-specific questionnaire was developed with 252 listed food frequency items. Calorie-adjusted correlation coefficients ranged from r = 0.374 to 0.600 (p < 0.001) for all analyzed nutrients except calcium. Estimates, ranks, trends and higher-level participant percentile placements for Vitamin B12 were similar with both methods. Questionnaire intakes were higher than recalls for most other nutrients. Both methods demonstrated similar trends in DRI adequacy assessment (e.g., significantly inadequate vitamin D intake among vegans). This vegan-specific questionnaire can be a useful assessment tool for health screening initiatives in U.S. vegan communities. PMID:25006856

Global 3-D imaging of mantle conductivity based on inversion of observatory C-responses—II. Data analysis and results  

NASA Astrophysics Data System (ADS)

The global 3-D electrical conductivity distribution in the mantle (in the depth range between 400 and 1600 km) is imaged by inverting C-responses estimated on a global net of geomagnetic observatories. Very long time-series (up to 51 years; 1957-2007) of hourly means of three components of the geomagnetic field from 281 geomagnetic observatories are collected and analysed. Special attention is given to data processing in order to obtain unbiased C-responses with trustworthy estimates of experimental errors in the period range from 2.9 to 104.2 d. After careful inspection of the obtained C-responses the data from 119 observatories are chosen for the further analysis. Squared coherency is used as a main quality indicator to detect (and then to exclude from consideration) observatories with a large noise-to-signal ratio. During this analysis we found that—along with the C-responses from high-latitude observatories (geomagnetic latitudes higher than 58°)—the C-responses from all low-latitude observatories (geomagnetic latitudes below 11°) also have very low squared coherencies, and thus cannot be used for global induction studies. We found that the C-responses from the selected 119 mid-latitude observatories show a huge variability both in real and imaginary parts, and we investigated to what extent the ocean effect can explain such a scatter. By performing the systematic model calculations we conclude that: (1) the variability due to the ocean effect is substantial, especially at shorter periods, and it is seen for periods up to 40 d or so; (2) the imaginary part of the C-responses is to a larger extent influenced by the oceans; (3) two types of anomalous C-response behaviour associated with the ocean effect can be distinguished; (4) to accurately reproduce the ocean effect a lateral resolution of 1°× 1° of the conductance distribution is needed, and (5) the ocean effect alone does not explain the whole variability of the observed C-responses. We also detected that part of the variability in the real part of the C-responses is due to the auroral effect. In addition we discovered that the auroral effect in the C-responses reveals strong longitudinal variability, at least in the Northern Hemisphere. Europe appears to be the region with smallest degree of distortion compared with North America and northern Asia. We found that the imaginary part of the C-responses is weakly affected by the auroral source, thus confirming the fact that in the considered period range the electromagnetic (EM) induction from the auroral electrojet is small. Assuming weak dependence of the auroral signals on the Earth's conductivity at considered periods, and longitudinal variability of the auroral effect, we developed a scheme to correct the experimental C-responses for this effect. With these developments and findings in mind we performed a number of regularized 3-D inversions of our experimental data in order to detect robust features in the recovered 3-D conductivity images. Although differing in details, all our 3-D inversions reveal a substantial level of lateral heterogeneity in the mantle at the depths between 410 and 1600 km. Conductivity values vary laterally by more than one order of magnitude between resistive and conductive regions. The maximum lateral variations of the conductivity have been detected in the layer at depths between 670 and 900 km. By comparing our global 3-D results with the results of independent global and semi-global 3-D conductivity studies, we conclude that 3-D conductivity mantle models produced so far are preliminary as different groups obtain disparate results, thus complicating quantitative comparison with seismic tomography or/and geodynamic models. In spite of this, our 3-D EM study and most other 3-D EM studies reveal at least two robust features: reduced conductivity beneath southern Europe and northern Africa, and enhanced conductivity in northeastern China.

The natural vegetation responses to the groundwater change resulting from ecological water conveyances to the lower Tarim River.  

PubMed

This paper takes the ecological water conveyance project (EWCP) that transfers water from the Bosten Lake, to Daxihaizi Reservoir, and finally to the Taitema Lake as a case study to analyze the dynamic change of the groundwater depth, the vegetation responses to the elevation of the groundwater depth as well as the relationship between the groundwater depth and the natural vegetation. The results from many years' monitoring in field indicate: (1) the groundwater depth has been elevating gradually with the increase in the times of watering and the elevation range has been expanding continuously in the lower reaches of Tarim River. Correspondingly, the natural vegetation has a favorable response to the elevation of the groundwater depth. The change of the natural vegetation has accordance with that of the groundwater depth. Such facts not only show that groundwater is a key factor to the growth of the native vegetation but also prove it is feasible that the degraded ecosystem can be restored and protected by the EWCP; (2) the results of analysis of the spatial-temporal response of the natural vegetation to watering reveals that the beneficial influence of the EWCP on the ecosystem in the lower Tarim River is a long-term process; (3) in terms of the function and structure of ecosystem after watering in the lower reaches of Tarim River, the EWCP does not still reach the goal of ecological restoration at a large spatial scale at present. Based on such monitoring results, some countermeasures and suggestions for the future restoration strategy are proposed so as to provide a theoretical basis for restoring and protecting the ecosystem in Tarim River, and meanwhile it can also provide some scientific references for implementing the similar ecological projects in other areas.

Effect of a metallized chamber upon the field response of a kicker magnet: simulations results and analytical calculations  

E-print Network

Metallized racetrack vacuum chambers will be used in the pulsed magnets of the Austrian cancer therapy and research facility, MedAustron. It is important that the metallization does not unduly degrade field rise and fall times or the flattop of the field pulse in the kicker magnets. This was of particular concern for a tune kicker magnet, which has a specified rise and fall time of 100 ns. The impact of the metallization, upon the transient field response, has been studied using Finite Element Method (FEM) simulations: the dependency of the field response to the metallization thickness and resistivity are presented in this paper and formulae for the field response, for a ramped transient excitation current, are given. An equivalent circuit for the metallization allows the effect of an arbitrary excitation to be studied, with a circuit simulator, and the circuit optimized. Furthermore, results of simulations of the effect of a magnetic brazing collar, located between the ceramic vacuum chamber and flange, of t...

A Review of Quality of Life Measures in Dry Eye Questionnaires  

PubMed Central

Purpose Dry eye disease (DED) is an ocular disease that affects 5% to 17% of the US population. Because of the negative effects of DED on patients’ quality of life (QOL), disease-specific questionnaires that assess QOL in patients with dry eyes are essential in the monitoring and management of this chronic ocular condition. This review provides clinicians and researchers with a summary of the current questionnaires available for assessing QOL in patients with dry eyes. Methods A systematic review of the literature was performed in March 2013. Results There are only 2 validated, reliable dry eye questionnaires with QOL measures currently available for clinic use: the Ocular Surface Disease Index (OSDI) and the Impact of Dry Eye on Everyday Life questionnaire (IDEEL). Multiple other dry eye questionnaires assess some degree of QOL, but they have either not been tested for validity and reliability or are limited in QOL measures they assess. Conclusions The OSDI and IDEEL are validated, reliable disease-specific questionnaires that assess QOL measures in patients with DED. Because of its extensive development process and multiple QOL measures, the IDEEL offers a more thorough assessment of the effect of DED on QOL for clinical trials, whereas the OSDI may be the more convenient option for clinical use as a result of its shorter completion time. Other questionnaires used to assess QOL in DED (eg, 25-item National Eye Institute Visual Function Questionnaire and Texas Eye Research and Technology Center DEQ) are fairly limited in this assessment. Finally, because of the negative effects of DED on QOL, this review emphasizes the importance of including QOL measures in future questionnaires for the monitoring and management of DED.

Complement Opsonization of HIV-1 Results in Decreased Antiviral and Inflammatory Responses in Immature Dendritic Cells via CR3  

PubMed Central

Immature dendritic cells (iDCs) in genital and rectal mucosa may be one of the first cells to come into contact with HIV-1 during sexual transmission of virus. HIV-1 activates the host complement system, which results in opsonization of virus by inactivated complement fragments, for example, iC3b. We investigated antiviral and inflammatory responses induced in human iDCs after exposure to free HIV-1 (F-HIV), complement-opsonized HIV-1 (C-HIV), and complement and Ab–opsonized HIV-1 (CI-HIV). F-HIV gave rise to a significantly higher expression of antiviral factors such as IFN-?, myxovirus resistance protein A, and IFN-stimulated genes, compared with C-HIV and CI-HIV. Additionally, F-HIV induced inflammatory factors such as IL-1?, IL-6, and TNF-?, whereas these responses were weakened or absent after C-HIV or CI-HIV exposure. The responses induced by F-HIV were TLR8-dependent with subsequent activation of IFN regulatory factor 1, p38, ERK, PI3K, and NF-?B pathways, whereas these responses were not induced by C-HIV, which instead induced activation of IFN regulatory factor 3 and Lyn. This modulation of TLR8 signaling was mediated by complement receptor 3 and led to enhanced infection. The impact that viral hijacking of the complement system has on iDC function could be an important immune evasion mechanism used by HIV-1 to establish infection in the host. PMID:25252956

Predicting response to initial therapy with interferon plus ribavirin in chronic hepatitis C using serum HCV RNA results during therapy.  

PubMed

In patients with chronic hepatitis C, 48 weeks of therapy with interferon (IFN) plus ribavirin results in a sustained virologic response of 40%. Preliminary analysis suggests that measuring HCV RNA at week 24, rather than week 12, might provide the best prediction of treatment response. To assess the clinical utility of serum HCV RNA determinations at different times during therapy as a predictor of a sustained virologic response we evaluated 912 treatment-naïve patients. Patients were randomized to receive IFN-alpha2b, 3 million units (MU) three times weekly (tiw), for 24 or 48 weeks with either ribavirin or placebo, and then followed for 24 weeks. Serum HCV RNA was measured at weeks 4 and 12 in patients treated for 24 weeks; at 4, 12, and 24 weeks during therapy in those treated for 48 weeks, and week 24 post-therapy in all patients. Sustained response was defined as loss of serum HCV RNA at week 24 follow-up. Other patients were considered virologic nonresponders. For patients receiving 48 weeks of combination therapy, detectable serum HCV RNA at week 24 predicted nonresponse (positive predictive value) in 99% of patients compared to 89% at week 12. In patients treated for 24 weeks, testing at week 12 was more predictive of nonresponse than testing at week 4 in the combination-therapy group but not in the monotherapy group. Hence, for combination therapy, testing for serum HCV RNA as a predictor of nonresponse is most accurate at week 24 of therapy; a positive test correctly identified 99% of nonresponders.

Chronic cough – assessment of treatment efficacy based on two questionnaires  

PubMed Central

Introduction Efficacy of chronic cough treatment is ambiguous. The aim of the study was to analyze chronic cough alleviation after specific treatment and the relationship between cough etiology and treatment efficacy. Material and methods A stepwise diagnostic approach was used to diagnose cough etiology in non-smoking adults with chronic cough. In all patients specific treatment was applied. Two different questionnaires – a visual analog scale and a 5-degree scale – were used to assess cough severity before and after 4-6 months of treatment. Results A significant correlation between pre-treatment and post-treatment results of both questionnaires was found (Spearman coefficient 0.43, p = 0.0003 and 0.73, p < 0.0001, respectively). Baseline questionnaire analysis revealed no differences in cough severity between patients with different cough causes or multiple cough causes. Although specific treatment resulted in a significant decrease of cough severity in the entire group, only partial improvement was noted. According to the visual analogue scale, a decrease of cough severity by at least 50% was achieved only in 54.4% of patients (37/68). Similarly, satisfactory improvement was noted in only 54.4% (37/68) of patients when using the 5-point scale. There were three sub-groups of patients, in whom no relevant decrease of cough severity was observed despite treatment: patients with 1. three coexisting cough causes, 2. non-asthmatic eosinophilic bronchitis, and 3. chronic idiopathic cough. Conclusions Cough severity does not depend on its etiology. Efficacy of chronic cough treatment in non-smoking patients is only moderate. PMID:25395948

[FIMA - Questionnaire for Health-Related Resource Use in an Elderly Population: Development and Pilot Study].  

PubMed

Due to demographic trends towards an ageing population resource use of health care will increase. By collecting health-related costs via questionnaires, the impact of socio-economic variables and other medical factors can be examined. In addition, only patient reported resource use accounts for out-of-pocket payments. Thus, it is necessary to develop an appropriate tool to collect the health-related resource use in an elderly population.The development of the FIMA (questionnaire for the use of medical and non-medical services in old age) was carried out in 6 steps. These included the determination of necessary questionnaire contents based on a literature review and the wording and layout were defined. Finally the questionnaire was tested in a pilot study and was modified.All direct medical and non-medical resource use excluding transportation and time costs were recorded. Productivity losses were not included. The recall time frames differed according to resource categories (7 days, 3 months, 12 months). For the pilot study, 63 questionnaires were analysed. The response rate was 69%. The questionnaire took an average of 21?min to complete. Three quarters of respondents completed the questionnaire without help and 90% rated the difficulty as easy or even very simple. There was good agreement between self-reported health-related quality of life and the resource use of nursing and domestic help (phi coefficient values between 0.52 and 0.58).The FIMA is a generic questionnaire which collects the health-related resource use within the older population groups.

Reliability of the Strengths and Difficulties Questionnaire in Japanese Preschool Children Aged 4–6 Years  

PubMed Central

Background The Strengths and Difficulties Questionnaire (SDQ) has been widely used as a brief behavioral screening. The aim of this study was to examine the internal consistency and test-retest reliability of the 3- to 4-year-old version of the SDQ (SDQ 3–4) in Japanese preschool children. Methods The SDQ 3–4 was administered to 754 parents who had 4- to 6-year-old children attending kindergartens or childcare centers in Wako City, Japan, at 2 different times (Time 1 and Time 2) over a 2-week interval between June and July 2012. Cronbach’s ? and correlation coefficients were used to examine internal consistency and test-retest reliability, respectively. Results Of 393 parents who returned their responses at Time 1 (response rate 52.1%), 383 were used for analysis after excluding 10 responses with missing data. Their children’s mean age was 4.7 (standard deviation 0.7) years. The internal consistency (Cronbach’s ?) was good for the total difficulties score (0.74) and the prosocial behavior scale (0.70). However, it was slightly worse for the emotional symptoms, conduct problems, and hyperactivity scales (0.61–0.66) and poor for the peer problems scale (0.45). Of the 383 included respondents at Time 1, 211 parents returned their responses at Time 2 (response rate: 55.1%). Test-retest reliability (correlation coefficients) was good (0.73–0.82), except for the peer problems scale (0.58). Conclusions The results support the reliability of the SDQ 3–4 being satisfactory for the total difficulties score and prosocial behavior scale and being acceptable for the emotional symptoms, conduct problems, and hyperactivity scales in Japanese preschool children aged 4–6 years.

The development and psychometric properties of the selective mutism questionnaire.  

PubMed

Research on selective mutism (SM) has been limited by the absence of standardized, psychometrically sound assessment measures. The purpose of our investigation was to present two studies that examined the factor structure and initial reliability and validity of the Selective Mutism Questionnaire (SMQ), a 17-item parent report measure of failure to speak related to SM. Study 1 (N = 589) utilized an Internet sample of parents of children ages 3 to 11 to demonstrate that the SMQ has a theoretically and clinically meaningful factor structure accounting for a significant portion of variance in responses with good internal consistency. Study 2 (N = 66) supported the validity of the SMQ in that scores discriminated clinic-referred children with SM from children with other anxiety disorders. Scores on the SMQ were correlated with measures of several theoretically and clinically important dimensions. PMID:18470781

The nonlinear elastic response of suspensions of rigid inclusions in rubber: I—An exact result for dilute suspensions  

NASA Astrophysics Data System (ADS)

A solution is constructed for the problem of the overall elastic response of ideal (Gaussian or, equivalently, Neo-Hookean) rubber reinforced by a dilute isotropic distribution of rigid particles under arbitrarily large deformations. The derivation makes use of a novel iterative homogenization technique in finite elasticity that allows to construct exact solutions for the homogenization problem of two-phase nonlinear elastic composites with particulate microstructures. The solution is fully explicit for axisymmetric loading, but is otherwise given in terms of an Eikonal partial differential equation in two variables for general loading conditions. In the limit of small deformations, it reduces to the classical Einstein-Smallwood result for dilute suspensions of rigid spherical particles. The solution is further confronted to 3D finite-element simulations for the large-deformation response of a rubber block containing a single rigid spherical inclusion of infinitesimal size. The two results are found to be in good agreement for all loading conditions. We conclude this work by devising a closed-form approximation to the constructed solution which is remarkably accurate and — as elaborated in Part II — proves particularly amenable as a fundamental building block to generate approximate solutions for suspensions with finite concentration of particles.

The seasonal response of the Held-Suarez climate model to prescribed ocean temperature anomalies. I - Results of decadal integrations  

NASA Technical Reports Server (NTRS)

Anomalies in ocean surface temperature have been identified as possible causes of variations in the climate of particular seasons or as a source of interannual climatic variability, and attempts have been made to forecast seasonal climate by using ocean temperatures as predictor variables. However, the seasonal atmospheric response to ocean temperature anomalies has not yet been systematically investigated with nonlinear models. The present investigation is concerned with ten-year integrations involving a model of intermediate complexity, the Held-Suarez climate model. The calculations have been performed to investigate the changes in seasonal climate which result from a fixed anomaly imposed on a seasonally varying, global ocean temperature field. Part I of the paper provides a report on the results of these decadal integrations. Attention is given to model properties, the experimental design, and the anomaly experiments.

Assessing the safety attitudes questionnaire (SAQ), German language version in Swiss university hospitals - a validation study  

PubMed Central

Background Improving patient safety has become a major focus of clinical care and research over the past two decades. An institution’s patient safety climate represents an essential component of ensuring a safe environment and thereby can be vital to the prevention of adverse events. Covering six patient safety related factors, the Safety Attitudes Questionnaire (SAQ) is a validated and widely used instrument to measure the patient safety climate in clinical areas. The objective of this study was to assess the psychometric properties of the German language version of the SAQ. Methods A survey was carried out in two University Hospitals in Switzerland in autumn 2009 where the SAQ was distributed to a sample of 406 nurses and physicians in medical and surgical wards. Following the American Educational Research Association guidelines, we tested the questionnaire validity by levels of evidence: content validity, internal structure and relations to other variables. Confirmatory factor analysis was used to examine factor structure. Cronbach’s alphas and inter-item correlations were calculated to examine internal consistency reliability. Results A total of 319 questionnaires were completed representing an overall response rate of 78.6%. For three items, the item content validity index was <0.75. Confirmatory factor analysis showed acceptable model fit (RMSEA = 0.045; CFI = 0.944) for the six-factor model. Additional exploratory factor analysis could not identify a better factor model. SAQ factor scores showed positive correlations with the Safety Organizing Scale (r = .56 - .72). The SAQ German version showed moderate to strong internal consistency reliability indices (Cronbach alpha = .65 - .83). Conclusions The German language version of the SAQ demonstrated acceptable to good psychometric properties and therefore shows promise to be a sound instrument to measure patient safety climate in Swiss hospital wards. However, the low item content validity and large number of missing responses for several items suggest that improvements and adaptations in translation are required for select items, especially within the perception of management scale. Following these revisions, psychometric properties should reassessed in a randomly selected sample and hospitals and departments prior to use in Swiss hospital settings. PMID:24016183

A nationwide postal questionnaire survey: the presence of airway guidelines in anaesthesia department in Sweden  

PubMed Central

Background In Sweden, airway guidelines aimed toward improving patient safety have been recommended by the Swedish Society of Anaesthesia and Intensive Care Medicine. Adherence to evidence-based airway guidelines is known to be generally poor in Sweden. The aim of this study was to determine whether airway guidelines are present in Swedish anaesthesia departments. Methods A nationwide postal questionnaire inquiring about the presence of airway guidelines was sent out to directors of Swedish anaesthesia departments (n?=?74). The structured questionnaire was based on a review of the Swedish Society of Anaesthesia and Intensive Care voluntary recommendations of guidelines for airway management. Mean, standard deviation, minimum/maximum, percentage (%) and number of general anaesthesia performed per year as frequency (n), were used to describe, each hospital type (university, county, private). For comparison between hospitals type and available written airway guidelines were cross tabulation used and analysed using Pearson’s Chi-Square tests. A p- value of less than 0 .05 was judged significant. Results In total 68 directors who were responsible for the anaesthesia departments returned the questionnaire, which give a response rate of 92% (n 68 of 74). The presence of guidelines showing an airway algorithm was reported by 68% of the departments; 52% reported having a written patient information card in case of a difficult airway and guidelines for difficult airways, respectively; 43% reported the presence of guidelines for preoperative assessment; 31% had guidelines for Rapid Sequence Intubation; 26% reported criteria for performing an awake intubation; and 21% reported guidelines for awake fibre-optic intubation. A prescription for the registered nurse anaesthetist for performing tracheal intubation was reported by 24%. The most frequently pre-printed preoperative elements in the anaesthesia record form were dental status and head and neck mobility. Conclusions Despite recommendations from the national anaesthesia society, the presence of airway guidelines in Swedish anaesthesia departments is low. From the perspective of safety for both patients and the anaesthesia staff, airway management guidelines should be considered a higher priority. PMID:24708670

Geriatrics in medical students’ curricula: questionnaire-based analysis  

PubMed Central

Background Demographic development is accompanied by an increasingly aging society. Concerning medical education, the treatment of older people as well as the scientific research and exploration of ageing aspects in the coming years need to be considered. Aim of the study was to ascertain medical students’ knowledge, interest, and attitudes regarding older patients and geriatric medicine. Methods Each participant completed a self-designed questionnaire. This questionnaire was based on three validated internationally recognised questionnaires (“Facts on Aging Quiz – FAQ”, “Expectations Regarding Aging – ERA” and the “Aging Semantic Differential – ASD”). The inquiry and survey were performed at the beginning of the summer term in 2012 at the University of Regensburg Medical School. Results A total of n?=?184/253 (72.7%) students participated in this survey. The results of the FAQ 25+ showed that respondents were able to answer an average of M?=?20.4 of 36 questions (56.7%) correctly (Median, Md?=?21; SD ±6.1). The personal attitudes and expectations of ageing averaged M?=?41.2 points on the Likert-scale that ranged from 0 to 100 (Md?=?40.4; SD ±13.7). Respondents’ attitudes towards the elderly (ASD 24) averaged M?=?3.5 points on the Likert-scale (range 1–7, Md 3.6, SD ±0.8). Conclusions In our investigation, medical students’ knowledge of ageing was comparable to previous surveys. Attitudes and expectations of ageing were more positive compared to previous studies. Overall, medical students expect markedly high cognitive capacities towards older people that can actively prevent cognitive impairment. However, medical students’ personal interest in medicine of ageing and older people seems to be rather slight. PMID:25062568

Experimental and theoretical studies of spectral alteration in ultrasonic waves resulting from nonlinear elastic response in rock  

SciTech Connect

Experiments in rock show a large nonlinear elastic wave response, far greater than that of gases, liquids and most other solids. The large response is attributed to structural defects in rock including microcracks and grain boundaries. In the earth, a large nonlinear response may be responsible for significant spectral alteration at amplitudes and distances currently considered to be well within the linear elastic regime.

Psychometric analysis of the Sexual Interest Cardsort Questionnaire.  

PubMed

Reliability, measured by Cronbach's coefficient alpha, and concurrent validity, measured by Pearson's r and polychoric correlation coefficients, were evaluated in this study. A sample of 371 sexual offenders referred to the Behavioral Medicine Institute of Atlanta for evaluation of sexual interests and behaviors by the courts were assessed using the Sexual Interest Cardsort Questionnaire (SI), a self-report measure of deviant and nondeviant sexual interest, as well as indicator variables obtained from classifications assigned by clinicians as a result of 2 hour-long, semistructured clinical interviews. Internal consistency of 75 items from the SI ranged from 0.71 to 0.96, across 15 categories of sexual interest and behavior. Additionally, the SI was shortened utilizing Cronbach's alphas to maintain a high level of internal consistency. The resulting questionnaire, the shortened SI (SIS), had 45 items and 15 categories. Cronbach's alpha ranged from 0.78 to 0.97. Utilizing Pearson's r and polychoric correlation coefficients, significant correlations were found for the 11 sexually deviant categories of the SI and indicator variables, and the 10 sexually deviant categories of the SIS and indicator variables. The SI and SIS showed a high level of reliability and concurrent validity. Clinical and research issues pertaining to the clinical assessment of male sexual offenders utilizing self-report and clinical interview data, both obtained as the result of comprehensive evaluations, are discussed.

Validation of the Mayo Sleep Questionnaire to Screen for REM Sleep Behavior Disorder in a Community-Based Sample  

PubMed Central

Objective: To validate a questionnaire focused on REM sleep behavior disorder (RBD) in a community-based sample. Background: RBD is a parasomnia manifested by recurrent dream enactment behavior during REM sleep. While confirmation of RBD requires the presence of REM sleep without atonia on polysomnography (PSG), a screening measure for RBD validated in older adults would be desirable for clinical and research purposes. Methods: We had previously developed the Mayo Sleep Questionnaire (MSQ) to screen for the presence of RBD and other sleep disorders. We assessed the validity of the MSQ by comparing the responses of subjects' bed partners with the findings on PSG. All subjects recruited from 10/04 to 12/08 in the Mayo Clinic Study of Aging—a population-based study of aging in Olmsted County, Minnesota—who had also undergone a previous PSG were the focus of this analysis. Results: The study sample included 128 subjects (104 male; median age 77 years [range 67-90]), with the following clinical diagnoses at baseline assessment: normal (n = 95), mild cognitive impairment (n = 30), and mild Alzheimer disease (n = 3). Nine (5%) subjects had RBD based on history and PSG evidence of REM sleep without atonia. The core question on recurrent dream enactment behavior yielded sensitivity (SN) of 100% and specificity (SP) of 95% for the diagnosis of RBD. The profile of responses on four additional subquestions on RBD improved specificity. Conclusions: These data suggest that the MSQ has adequate SN and SP for the diagnosis of RBD among elderly subjects in a community-based sample.

Psychometric properties of the national eye institute refractive error correction quality-of-life questionnaire among Iranian patients  

PubMed Central

Background and Aim: To evaluate the psychometric properties of the national Eye Institute refractive error correction quality of life questionnaire (NEI-RQL-42) among Iranian patients with refractive errors. Materials and Methods: Two samples of patients (n1 = 296, n2 = 95) were consecutively selected from the eye clinic of the Boo-Ali Hospital, Qazvin. A forward-backward procedure was conducted to translate and cross-culturally adapt the Iranian version of the NEI-RQL-42. A homogeneity, stability, and reliability test was conducted for the first sample after a two-week interval. Convergent validity was computed using the correlation between the NEI-RQL-42 subscale scores, National Eye Institute-Visual Functioning Questionnaire (NEI-VFQ-25), and the Short Form-36 (SF-36). Furthermore, Known-group analysis was performed, to determine the discriminant validity between the subgroups of patients with hyperopia, emmetropia, and myopia. Responsiveness to clinical change was tested by administering NEI-RQL-42 on the second sample that was scheduled for surgery. Results: Homogeneity was satisfactory with the Cronbach’s alpha coefficients ranging between 0.70 and 0.92. The 13 subscales of the NEI-RQL-42 showed a considerable stability in intra-class-correlation (ICC) ranging between 0.70 and 0.89. Positive correlation coefficients were found among all subscales of the NEI-RQL-42 and the other quality-of-life instruments (NEI-VFQ-25 and SF-36). The NEI-VFQ-25 displayed excellent discriminant validity to differentiate the subgroups of patients, and was found to be responsive to change after the surgical correction at three months. Conclusions: The Iranian version of the NEI-RQL-42 is a valid and reliable instrument to assess refractive error correction quality-of-life in Iranian patients. Moreover this questionnaire can be used to evaluate the effectiveness of interventions in patients with refractive errors. PMID:23772124

Mechanisms driving ocean carbon cycle response to rising atmospheric CO2: results from the Community Earth System Model, version 1  

NASA Astrophysics Data System (ADS)

We present results from simulations conducted with the Community Earth System Model, version 1 (CESM1 (BGC)), which includes marine ecosystem dynamics and ocean biogeochemistry. We consider fully-coupled 21st century integrations, forced with Representative Concentration Pathway (RCP) projections of radiatively-active atmospheric constituents. We characterize climate-carbon feedbacks on ocean CO2 fluxes in these integrations, using control simulations that include the atmospheric CO2 transient as a boundary condition for sea-air fluxes, but its radiative effects (and those of other transients) are turned off. In RCP8.5 under a constant climate, the ocean carbon sink for anthropogenic CO2 began to stabilize around 2080, due to nonlinearities in carbonate chemistry. Climate change caused further reductions in the ocean carbon sink, such that by 2100, the ocean absorbed about 1 Pg C yr-1 less than under constant climate conditions. The carbon cycle response to climate change differed regionally. The North Atlantic was most strongly affected in a relative sense, experiencing a reduction in uptake due to climate change in excess of 40% by 2100. Strong freshwater forcing in the Subpolar gyre and Labrador Sea regions caused diminished deep convection, which curtailed the supply of nutrients, thereby forcing reductions in biological carbon export and diminished CO2 uptake. The Southern Ocean, by contrast, experienced a smaller, relative climate-induced reduction in CO2 uptake: less than 20%. In this region, climate change caused a poleward shift and intensification of the westerly winds, which enhanced the upper cell of the meridional overturning circulation; concomitant changes, however, resulted in a reduction in Antarctic Bottom Water formation. Shifting circulation patterns resulted in a net reduction in the resolved advective transport of carbon out of the surface ocean; increased eddy-induced mixing exacerbated this effect: eddy-induced mixing is parameterized (responsive to winds) and a net source of carbon to the surface of the Southern Ocean. Since the Southern Ocean is characterized by ample surface nutrient, reductions in vertical resupply due to enhanced stratification resulted in little change to biological export flux. Climate change caused a reduction in eastern equatorial Pacific outgassing, predominantly driven by enhanced biological production; the mechanisms for this are complex. Stratification resulted in greater macronutrient limitation in regions upstream of the eastern equatorial Pacific upwelling zone. Reduced production in these regions resulted in decreased iron utilization, thereby alleviating iron limitation in the eastern equatorial Pacific upwelling region.

Psychometric Properties of the Nurses Work Functioning Questionnaire (NWFQ)  

PubMed Central

Objectives The Nurses Work Functioning Questionnaire (NWFQ) is a 50-item self-report questionnaire specifically developed for nurses and allied health professionals. Its seven subscales measure impairments in the work functioning due to common mental disorders. Aim of this study is to evaluate the psychometric properties of the NWFQ, by assessing reproducibility and construct validity. Methods The questionnaire was administered to 314 nurses and allied health professionals with a re-test in 112 subjects. Reproducibility was assessed by the intraclass correlations coefficients (ICC) and the standard error of measurement (SEM). For construct validity, correlations were calculated with a general work functioning scale, the Endicott Work Productivity Scale (EWPS) (convergent validity) and with a physical functioning scale (divergent validity). For discriminative validity, a Mann Whitney U test was performed testing for significant differences between subjects with mental health complaints and without. Results All subscales showed good reliability (ICC: 0.72–0.86), except for one (ICC?=?0.16). Convergent validity was good in six subscales, correlations ranged from 0.38–0.62. However, in one subscale the correlation with the EWPS was too low (0.22). Divergent validity was good in all subscales based on correlations ranged from (?0.06)–(?0.23). Discriminative validity was good in all subscales, based on significant differences between subjects with and without mental health complaints (p<0.001–p?=?0.003). Conclusion The NWFQ demonstrates good psychometric properties, for six of the seven subscales. Subscale “impaired decision making” needs improvement before further use. PMID:22087231

HIF-1? depletion results in SP1-mediated cell cycle disruption and alters the cellular response to chemotherapeutic drugs.  

PubMed

Hypoxia inducible factor (HIF) is the major transcription factor involved in the regulation of the cellular response to hypoxia, or low oxygen tensions. Even though HIF-1 function is mostly studied following hypoxic stress, well oxygenated areas of several diseased tissues have detectable levels of this transcription factor. Therefore, it is surprising how little is known about the function of HIF in normoxia. This study seeks to fill this gap. Using transient HIF-1? knockdown, as well as, stable cell lines generated using short hairpin RNAs (shRNA), we have further characterized the role of HIF-1? in normoxia. Our data reveals that knockdown of HIF-1? results in a significant increase in cells in the G1 phase of the cell cycle. We find that HIF-1? depletion increases the protein and mRNA of both p21 and p27. p21 is induced via, at least in part, p53-independent but SP1-dependent mechanisms. Interestingly, HIF-1? knockdown also alters the cellular response to chemotherapeutic agents. These data have important implications in not only for the further understanding of HIF-1?, a major transcription factor, but also for the use of HIF-targeted and combination therapies in cancer treatment.

Involving patients in detecting quality gaps in a fragmented healthcare system: development of a questionnaire for Patients' Experiences Across Health Care Sectors (PEACS)  

PubMed Central

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

Millennial scale system impulse response of polar climates - deconvolution results between ? 18O records from Greenland and Antarctica  

NASA Astrophysics Data System (ADS)

Deconvolution has long been used in science to recover real input given a system's impulse response and output. In this study, we applied spectral division deconvolution to select, polar, ? 18O time series to investigate the possible relationship between the climates of the Polar Regions, i.e. the equivalent to a climate system's ';impulse response.' While the records may be the result of nonlinear processes, deconvolution remains an appropriate tool because the two polar climates are synchronized, forming a Hilbert transform pair. In order to compare records, the age models of three Greenland and four Antarctica records have been matched via a Monte Carlo method using the methane-matched pair GRIP and BYRD as a basis for the calculations. For all twelve polar pairs, various deconvolution schemes (Wiener, Damped Least Squares, Tikhonov, Kalman filter) give consistent, quasi-periodic, impulse responses of the system. Multitaper analysis reveals strong, millennia scale, quasi-periodic oscillations in these system responses with a range of 2,500 to 1,000 years. These are not symmetric, as the transfer function from north to south differs from that of south to north. However, the difference is systematic and occurs in the predominant period of the deconvolved signals. Specifically, the north to south transfer function is generally of longer period than the south to north transfer function. High amplitude power peaks at 5.0ky to 1.7ky characterize the former, while the latter contains peaks at mostly short periods, with a range of 2.5ky to 1.0ky. Consistent with many observations, the deconvolved, quasi-periodic, transfer functions share the predominant periodicities found in the data, some of which are likely related to solar forcing (2.5-1.0ky), while some are probably indicative of the internal oscillations of the climate system (1.6-1.4ky). The approximately 1.5 ky transfer function may represent the internal periodicity of the system, perhaps even related to the periodicity of the thermo-haline circulation (THC). Simplified models of the polar climate fluctuations are shown to support these findings.

Developing questionnaires for educational research: AMEE Guide No. 87  

PubMed Central

In this AMEE Guide, we consider the design and development of self-administered surveys, commonly called questionnaires. Questionnaires are widely employed in medical education research. Unfortunately, the processes used to develop such questionnaires vary in quality and lack consistent, rigorous standards. Consequently, the quality of the questionnaires used in medical education research is highly variable. To address this problem, this AMEE Guide presents a systematic, seven-step process for designing high-quality questionnaires, with particular emphasis on developing survey scales. These seven steps do not address all aspects of survey design, nor do they represent the only way to develop a high-quality questionnaire. Instead, these steps synthesize multiple survey design techniques and organize them into a cohesive process for questionnaire developers of all levels. Addressing each of these steps systematically will improve the probabilities that survey designers will accurately measure what they intend to measure. PMID:24661014

The SF36 health survey questionnaire: an outcome measure suitable for routine use within the NHS?  

PubMed Central

OBJECTIVE--To assess the validity, reliability, and acceptability of the short form 36 (SF 36) health survey questionnaire (a shortened version of a battery of 149 health status questions) as a measure of patient outcome in a broad sample of patients suffering from four common clinical conditions. DESIGN--Postal questionnaire, followed up by two reminders at two week intervals. SETTING--Clinics and four training practices in north east Scotland. SUBJECTS--Over 1700 patients aged 16-86 with one of four conditions--low back pain, menorrhagia, suspected peptic ulcer, or varicose veins--and a comparison sample of 900 members of the general population. MAIN OUTCOME MEASURES--The eight scales within the SF36 health profile. RESULTS--The response rate exceeded 75% in the patient population (1310 respondents). The SF36 satisfied rigorous psychometric criteria for validity and internal consistency. Clinical validity was shown by the distinctive profiles generated for each condition, each of which differed from that in the general population in a predictable manner. Furthermore, SF36 scores were lower in referred patients than in patients not referred and were closely related to general practitioners' perceptions of severity. CONCLUSIONS--These results provide support for the SF36 as a potential measure of patient outcome within the NHS. The SF36 seems acceptable to patients, internally consistent, and a valid measure of the health status of a wide range of patients. Before it can be used in the new health service, however, its sensitivity to changes in health status over time must also be tested. PMID:8518640

Construction of a questionnaire for readiness to reconcile in victims of human rights violations  

PubMed Central

Background Post-conflict reconciliation is supposed to have a positive impact on survivors of war and conflict. However, knowledge is limited as validated questionnaires to assess individual readiness to reconcile in the context of human rights violations are still missing. Objectives This study aimed to develop and pilot-test a questionnaire to assess individual readiness to reconcile in victims of human rights violations. Methods The questionnaire was developed and pilot-tested in a sample of 60 adult Kurdish refugees from Turkey. In addition to the questionnaire, trauma exposure, Posttraumatic Stress Disorder (PTSD), depression, anxiety, perceived emotional closeness to the Kurdish people as well as the participants’ ability to differentiate between perpetrators and the people in general were assessed in structured interviews, and their associations with readiness to reconcile were analyzed. Results Factor and item analysis resulted in an 18-item questionnaire with three subscales (openness to interactions; absence of feelings of revenge; openness to conflict resolution). Cronbach's ? for the subscales ranged from 0.74 to 0.90, explaining 61% of the total variance. The ability to differentiate between perpetrators and people in general and perceived emotional closeness were the best predictors for readiness to reconcile. The level of trauma exposure was not linked to readiness to reconcile. Although readiness to reconcile was negatively related to PTSD, depression and anxiety, none of these associations reached statistical significance. Conclusions The questionnaire appears to be a reliable measure with good psychometric properties. Further validations in different samples are needed. PMID:22893837

Environmental education curriculum evaluation questionnaire: A reliability and validity study  

NASA Astrophysics Data System (ADS)

The intention of this research project was to bridge the gap between social science research and application to the environmental domain through the development of a theoretically derived instrument designed to give educators a template by which to evaluate environmental education curricula. The theoretical base for instrument development was provided by several developmental theories such as Piaget's theory of cognitive development, Developmental Systems Theory, Life-span Perspective, as well as curriculum research within the area of environmental education. This theoretical base fueled the generation of a list of components which were then translated into a questionnaire with specific questions relevant to the environmental education domain. The specific research question for this project is: Can a valid assessment instrument based largely on human development and education theory be developed that reliably discriminates high, moderate, and low quality in environmental education curricula? The types of analyses conducted to answer this question were interrater reliability (percent agreement, Cohen's Kappa coefficient, Pearson's Product-Moment correlation coefficient), test-retest reliability (percent agreement, correlation), and criterion-related validity (correlation). Face validity and content validity were also assessed through thorough reviews. Overall results indicate that 29% of the questions on the questionnaire demonstrated a high level of interrater reliability and 43% of the questions demonstrated a moderate level of interrater reliability. Seventy-one percent of the questions demonstrated a high test-retest reliability and 5% a moderate level. Fifty-five percent of the questions on the questionnaire were reliable (high or moderate) both across time and raters. Only eight questions (8%) did not show either interrater or test-retest reliability. The global overall rating of high, medium, or low quality was reliable across both coders and time, indicating that the questionnaire can discriminate differences in quality of environmental education curricula. Of the 35 curricula evaluated, 6 were high quality, 14 were medium quality and 15 were low quality. The criterion-related validity of the instrument is at current time unable to be established due to the lack of comparable measures or a concretely usable set of multidisciplinary standards. Face and content validity were sufficiently demonstrated.

Psychometric Evaluation of the Persian Version of the ‘Aging Male Scales’ Questionnaire  

PubMed Central

Background: Men, much like women, are faced with age-related menopause-like symptoms as they age. In recent years, increasing attention has been drawn to clinical research into elderly men and their health-related quality of life. The Aging Male Scales (AMS) questionnaire is an international tool for assessing the health-related quality of life in elderly men. Hence far this questionnaire has not been subjected to psychometric assessment in Iran. This study aims to evaluate the validity and reliability of the Persian version of the AMS questionnaire specific to the health of elderly men in Iran. Methods: To validate this instrument, a cross-sectional study was conducted on 521 healthy Iranian men aged 40-65 years old, who attended the blood transfusion center clinic between February 2011 and June 2012. The English version of the AMS questionnaire was translated to Persian and then back-translated. To determine the reliability of the AMS questionnaire, internal consistency was evaluated and test-retest was done. The questionnaire was validated using convergent and structural validity methods. To assess the factor structure of the questionnaire, a correlation matrix of questions and domains was used. Results: Cronbach's alpha was higher than 0.7 (0.73-0.88) in all domains. A Pearson's correlation coefficient of 0.87 between pretest and posttest indicated a high correlation and an acceptable reliability. The convergent validity of the questionnaire was found acceptable by calculating the correlation between the domains and items-total correlation ranging 0.40-0.85, except for question 14 that had a 0.28 correlation with the whole test. The criterion-related validity of the questionnaire in the psychological domain was confirmed with the “two-item Patient Health Questionnaire” (r = 0.63, P < 0.001). Conclusions: According to the results, the Persian version of the AMS questionnaire has high validity and reliability and may be used to assess the health-related quality of life of men between 40 and 65 years old.

Designing and Validation a Visual Fatigue Questionnaire for Video Display Terminals Operators  

PubMed Central

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 has a very remarkable validity and reliability. Using this questionnaire and its findings, one will be able to identify, assess and finally prevent the effective factors of VDT users’ visual fatigue. PMID:25104995

Functional Gastrointestinal Disorders Diagnosed by Rome III Questionnaire in Korea  

PubMed Central

Background/Aims Rome criteria classifying functional gastrointestinal disorder (FGID) were updated. The aims of this study were to assess the spectra of FGID and to evaluate the applicability of Rome III criteria in Korea. Methods New patients who visited 2 primary clinics and 2 tertiary care hospitals were consecutively invited to complete questionnaires. These consisted of questionnaires for FGID based on Rome III criteria and symptom checklist-90-revised for somatization, depression and anxiety. Results A total of 786 patients was participated. Among them, FGID was observed in 49.7%. In the patients with FGID, functional dyspepsia was most common (46.0%) followed by irritable bowel syndrome (IBS, 40.2%). Functional dyspepsia was most common both in the primary care clinics and tertiary care hospitals. Postprandial distress syndrome was the most common subtype and the frequency of epigastric pain syndrome was low. There were few responders for constipation as Bristol types 1 and 2 and for diarrhea as types 6 and 7 in subtype classification using the Bristol Stool Form Scale. Thereby, unspecified IBS defined by stool form was unexpectedly common in 43.9% of IBS, whereas unspedified IBS defined by Rome III definition was 5.1%. Patients with overlap FGIDs had higher score of anxiety, depression or somatization. Conclusions FGIDs were common both in primary care clinics and tertiary care hospitals of Korea. Overlap FGIDs is still common by Rome III criteria, which may limits its wide application. PMID:21860820

Development and initial validation of the Performance Skills Questionnaire (PSQ).  

PubMed

The objectives of this study was to develop and test the psychometric properties of the Performance Skills Questionnaire (PSQ), addressed to measure performance skills of preschoolers, as reported by their parents. Participants included 231 children ranging in age from 4 to 6 years old, with mild to moderate developmental disabilities and 240 children without disabilities at same age range. Internal consistency, test-retest, construct validity, and divergent and convergent validity were assessed. The PSQ has shown good internal reliability, and temporal stability. Construct validity was supported by factor analysis which yielded 3 factors that explained almost 52% of the total variance. Significant differences were found between known groups. Convergent and divergent validity were supported by significant correlations with Visual-Motor Integration (VMI) test, and the Children Participation Questionnaire (CPQ). The PSQ is a unique tool that measures performance skills based on preschool children's everyday function. Results provide evidence in support of the PSQ as a reliable and psychometrically sound instrument. PMID:19709854

The development of the predisposition to dehydration questionnaire.  

PubMed

The role played by hydration in general health and well-being is an emerging public health issue, yet there are few tools available to monitor its status in large populations. The aim was therefore to develop a questionnaire that assesses individual differences in the tendency to lose body fluid in a warm environment and hence become dehydrated. Fifty-three subjects sat in a room at 30?°C for four hours and changes in mood and measures of hydration were monitored. There were marked individual differences in the loss of body mass that differed from 0.24% to 2.39%. Females who reported habitually drinking a lot had more water in their diet and at baseline the osmolality of urine was lower. After being subject to heat, those who reported habitually drinking more produced more urine, had a lower urine osmolality at the end of the study, and overall more body mass was lost. Females who reported that they responded badly to heat were more confused, unsure and depressed after four hours at 30?°C. In males those reporting that they habitually drank to a greater extent had more water in the diet, and also those who dealt badly with heat habitually drank more. It was concluded that particularly in females, questionnaire measures were able to predict changes in hydration that result from a warm environment. PMID:25477317

Patient-reported physical activity questionnaires: A systematic review of content and format  

PubMed Central

Background Many patients with chronic illness are limited in their physical activities. This systematic review evaluates the content and format of patient-reported outcome (PRO) questionnaires that measure physical activity in elderly and chronically ill populations. Methods Questionnaires were identified by a systematic literature search of electronic databases (Medline, Embase, PsychINFO & CINAHL), hand searches (reference sections and PROQOLID database) and expert input. A qualitative analysis was conducted to assess the content and format of the questionnaires and a Venn diagram was produced to illustrate this. Each stage of the review process was conducted by at least two independent reviewers. Results 104 questionnaires fulfilled our criteria. From these, 182 physical activity domains and 1965 items were extracted. Initial qualitative analysis of the domains found 11 categories. Further synthesis of the domains found 4 broad categories: 'physical activity related to general activities and mobility', 'physical activity related to activities of daily living', 'physical activity related to work, social or leisure time activities', and '(disease-specific) symptoms related to physical activity'. The Venn diagram showed that no questionnaires covered all 4 categories and that the '(disease-specific) symptoms related to physical activity' category was often not combined with the other categories. Conclusions A large number of questionnaires with a broad range of physical activity content were identified. Although the content could be broadly organised, there was no consensus on the content and format of physical activity PRO questionnaires in elderly and chronically ill populations. Nevertheless, this systematic review will help investigators to select a physical activity PRO questionnaire that best serves their research question and context. PMID:22414164

The Heritability of Cluster B Personality Disorders Assessed both by Personal Interview and Questionnaire  

PubMed Central

Whereas the heritability of common personality traits has been firmly established, the results of the few published studies on personality disorders (PDs) are highly divergent, with some studies finding high heredity and others very low. A problem with assessing personality disorders by means of interview is errors connected with interviewer bias. A way to overcome the problem is to use self-report questionnaires in addition to interviews. This study used both interview and questionnaire for assessing DSM-IV Cluster B personality disorders: antisocial personality disorder (APD), borderline (BPD), narcissistic (NPD), and histrionic (HPD). We assessed close to 2,800 twins from the Norwegian Institute of Public Health Twin Panel using a self-report questionnaire and, a few years later, the Structured Interview for DSM-IV Personality (SIDP-IV). Items from the self-report questionnaire that best predicted the PDs captured by the interview were then selected. Measurement models combining questionnaire and interview information were applied and were fitted using Mx. Whereas the heritability of Cluster B PDs assessed by interview was around .30, and around .40–.50 when assessed by self-report questionnaire, the heritability of the convergent latent factor, including information from both interview and self-report questionnaire was .69 for APD, .67 for BPD, .71 for NPD, and .63 for HPD. As is usually found for personality, the effect of shared-in families (familial) environment was zero. In conclusion, when both interview and self-report questionnaire are taken into account, the heritability of Cluster B PD appears to be in the upper range of previous findings for mental disorders.

Amazon Forest Response to Changes in Rainfall Regime: Results from an Individual-Based Dynamic Vegetation Model  

NASA Astrophysics Data System (ADS)

The Amazon is the largest tropical rainforest in the world, and thus plays a major role on global water, energy, and carbon cycles. However, it is still unknown how the Amazon forest will respond to the ongoing changes in climate, especially droughts, which are expected to become more frequent. To help answering this question, in this thesis I developed and improved the representation of biophysical processes and photosynthesis in the Ecosystem Demography model (ED-2.2), an individual-based land ecosystem model. I also evaluated the model biophysics against multiple data sets for multiple forest and savannah sites in tropical South America. Results of this comparison showed that ED-2.2 is able to represent the radiation and water cycles, but exaggerates heterotrophic respiration seasonality. Also, the model generally predicted correct distribution of biomass across different areas, although it overestimated biomass in subtropical savannahs. To evaluate the forest resilience to droughts, I used ED-2.2 to simulate the plant community dynamics at two sites in Eastern Amazonia, and developed scenarios by resampling observed annual rainfall but increasing the probability of selecting dry years. While the model predicted little response at French Guiana, results at the mid-Eastern Amazonia site indicated substantial biomass loss at modest rainfall reductions. Also, the response to drier climate varied within the plant community, with evergreen, early-successional, and larger trees being the most susceptible. The model also suggests that competition for water during prolonged periods of drought caused the largest impact on larger trees, when insufficient wet season rainfall did not recharge deeper soil layers. Finally, results suggested that a decrease in return period of long-lasting droughts could prevent ecosystem recovery. Using different rainfall datasets, I defined vulnerability based on the change in climate needed to reduce the return period of long droughts. The most vulnerable areas would be near Southeastern edge, a large band in mid-Eastern Amazonia, Western and Northern Bolivia and areas in Eastern Peru, whereas areas in mid-Southern Amazonia could be surprisingly resilient.

Adakitic (tonalitic-trondhjemitic) magmas resulting from eclogite decompression and dehydration melting during exhumation in response to continental collision  

NASA Astrophysics Data System (ADS)

Modern adakite or adakitic rocks are thought to result from partial melting of younger and thus warmer subducting ocean crust in subduction zones, with the melt interacting with or without mantle wedge peridotite during ascent, or from melting of thickened mafic lower crust. Here we show that adakitic (tonalitic-trondhjemitic) melts can also be produced by eclogite decompression during exhumation of subducted and metamorphosed oceanic/continental crust in response to continental collision, as exemplified by the adakitic rocks genetically associated with the early Paleozoic North Qaidam ultra-high pressure metamorphic (UHPM) belt on the northern margin of the Greater Tibetan Plateau. We present field evidence for partial melting of eclogite and its products, including adakitic melt, volumetrically significant plutons evolved from the melt, cumulate rocks precipitated from the melt, and associated granulitic residues. This “adakitic assemblage” records a clear progression from eclogite decompression and heating to partial melting, to melt fractionation and ascent/percolation in response to exhumation of the UHPM package. The garnetite and garnet-rich layers in the adakitic assemblage are of cumulate origin from the adakitic melt at high pressure, and accommodate much of the Nb-Ta-Ti. Zircon SHRIMP U-Pb dating shows that partial melting of the eclogite took place at ?435-410 Ma, which postdates the seafloor subduction (>440 Ma) and temporally overlaps the UHPM (?440-425 Ma). While the geological context and the timing of adakite melt formation we observe differ from the prevailing models, our observations and documentations demonstrate that eclogite melting during UHPM exhumation may be important in contributing to crustal growth.

Measuring Metacognition in Cancer: Validation of the Metacognitions Questionnaire 30 (MCQ-30)  

PubMed Central

Objective The Metacognitions Questionnaire 30 assesses metacognitive beliefs and processes which are central to the metacognitive model of emotional disorder. As recent studies have begun to explore the utility of this model for understanding emotional distress after cancer diagnosis, it is important also to assess the validity of the Metacognitions Questionnaire 30 for use in cancer populations. Methods 229 patients with primary breast or prostate cancer completed the Metacognitions Questionnaire 30 and the Hospital Anxiety and Depression Scale pre-treatment and again 12 months later. The structure and validity of the Metacognitions Questionnaire 30 were assessed using factor analyses and structural equation modelling. Results Confirmatory and exploratory factor analyses provided evidence supporting the validity of the previously published 5-factor structure of the Metacognitions Questionnaire 30. Specifically, both pre-treatment and 12 months later, this solution provided the best fit to the data and all items loaded on their expected factors. Structural equation modelling indicated that two dimensions of metacognition (positive and negative beliefs about worry) were significantly associated with anxiety and depression as predicted, providing further evidence of validity. Conclusions These findings provide initial evidence that the Metacognitions Questionnaire 30 is a valid measure for use in cancer populations. PMID:25215527

A screening questionnaire for voice problems after treatment of early glottic cancer  

SciTech Connect

Purpose: After treatment for early glottic cancer, a considerable number of patients end up with voice problems interfering with daily life activities. A 5-item screening questionnaire was designed for detection of voice impairment. The purpose of this study is to assess psychometric properties of this questionnaire in clinical practice. Methods and Materials: The questionnaire was completed by 110 controls without voice complaints and 177 patients after radiotherapy or laser surgery for early glottic cancer. Results: Based on normative data of the controls, a score of 5 or less on at least 1 of the 5 questions was considered to state overall voice impairment. Reliability of the questionnaire proved to be good. Voice impairment was reported in 44% of the patients treated with radiotherapy vs. 29% of the patients treated with endoscopic laser surgery. Conclusions: The questionnaire proved to be a reliable, valid, and feasible method to detect voice impairment in daily life. The questionnaire is easy to fill in, and interpretation is straightforward. It is useful for both radiation oncologists and otorhinolaryngologists in their follow-up of patients treated for early glottic cancer.

Assessment of Questionnaires Measuring Quality of Life in Infertile Couples: A Systematic Review  

PubMed Central

Background Infertility has potentially inappropriate effects on quality of life in infertile couples. Various general and specific questionnaires have been structured for assessing different aspects of quality of life in infertile men, women, or couples. The present systematic review was designed to assess these questionnaires and also identify different factors affecting infertile couples based on the aforesaid questionnaires. Methods The research strategy involved general and specific terms in relation to couples's infertility and their quality of life. A review was done for studies published from 1982 to 2012 that were indexed in Medline, ISI Web of Science and Scopus as well as abstract books on this subject. We also corresponded with the authors of the references in related studies for introducing more resources and references. Results In all reviewed studies, different aspects of the quality of life in couples were evaluated including sexual, psychological, social, communicational, environmental, occupational, medical, as well as economical ones. In total, after initial screening of all studies, 10 general and 2 specific questionnaires were retrieved. Although no meta-analysis was found in the review, infertility had a negative effect on quality of life in couples. Conclusion This study revealed that some general questionnaires such as SF-36 and WHO-QOL were mostly used for assessing quality of life in infertile couples and some specific questionnaires such as FERTI-QoL and Fertility Problem Inventory were rarely used. Thus, it seems that the evaluation of quality of life in infertile couples needs valid instruments for measurement. PMID:24163794

Adverse Reactions to Foods and Food Allergy: Development and Reproducibility of a Questionnaire for Clinical Diagnosis  

PubMed Central

Objective. To develop a questionnaire as a screening tool for adverse reactions to foods in children and to assess the technical reproducibility by test-retest. Methods. Reproducibility of the questionnaire was performed by the literature review, preparing the preliminary questionnaire, peer review, pretest, and retest analysis. The study of the test-retest reproducibility was cross-sectional and descriptive. Kappa coefficient was used to study the reproducibility of the questionnaire. The sample consisted of 125 2–4 year-old children from 15 daycare centers in Recife, Brazil, and interviews with parents or caregivers were used to collect data. Results. From the total children, sixty-three were boys (50.4%), forty-six were two years old (36.8%), forty-seven were three years old (37.6%), and thirty-two were four years old (25.6%). Forty caregivers reported that their child had health problems with food. Most frequently reported offending foods were milk, peanuts, shrimp, and chocolate. Nine questions showed a good Kappa index (?0,6). Conclusions. The questionnaire used needs to be resized and reshaped on the basis of the issues with good internal consistency and reproducibility. The use of a validated and reproducible questionnaire in the children represents an important contribution towards assessing an eventual rise in overt food allergy. PMID:24198840

Preliminary validation of the military low back pain questionnaire.  

PubMed

Soldiers must perform a variety of physical tasks that the civilian population does not. The Modified Oswestry Disability Index (M-ODI) is the most widely used measure of function in patients with low back pain but does not include military tasks. The Military Low Back Pain Questionnaire (MBQ) was developed by military Physical Therapists to include tasks such as wearing body armor. The purpose of this study was to provide preliminary evidence for the reliability, responsiveness, and validity of the MBQ in nondeployed Soldiers. The MBQ had good reliability compared to the M-ODI. The inter-rater correlation coefficient for the M-ODI was 0.79 and 0.75 for the MBQ. Cronbach's alpha was 0.75 and 0.85 for the M-ODI and MBQ, respectively. The minimal detectable change for the M-ODI was 21.03 and 22.97 for the MBQ. Responsiveness was assessed using a global rating of change; area under the curve for the M-ODI was 0.82 and 0.90 for the MBQ. The correlation between the M-ODI and the MBQ was r = 0.80 indicating good concurrent validity. The MBQ was as reliable as the M-ODI in an Army population. There were trends in the psychometrics suggesting the MBQ may be more sensitive to change than the M-ODI in this population. PMID:24491605

[Questionnaire survey of full-time occupational health physicians in Japan].  

PubMed

In August 1987 the University of Occupational and Environmental Health conducted a mail questionnaire survey on occupational health physicians (OHPs) located throughout Japan. The objective was to obtain preliminary information concerning the actual situation of OHPs together with their opinions on post-graduate training in this field. A summary of the results based on 187 valid responses (valid response rate = 59.4%) is as follows: 1. Age distribution of the respondents was in excess of 55 years of age (mean age of 61.4 yr), suggesting aging of the work force. 2. Comparison of the present age with period in present position revealed that a significant proportion of the respondents assumed their current position following retirement from clinical service. 3. Routine work schedules such as clinical activities and making site visits within factory tended to be influenced by the number of employees. 4. Conduct of special physical examinations on workers in hazardous environments was rated the highest among the necessary abilities of OHPs. 5. It was found that 30-34 years of age and 2-5 years of clinical experience were the minimal qualifications for a full time OHP. PMID:2754859

Use of Averaged Norbeck Social Support Questionnaire Scores  

PubMed Central

Background. Averaged Norbeck Social Support Questionnaire (NSSQ) support scores remove the influence of network size variability but may unduly lower scores for participants with large networks. Objectives. To evaluate the use of averaged NSSQ scores. Method. Pearson correlations determined if averaged scores decreased as network size increased across three samples. Then, Pearson correlations between a criterion variable and both averaged and raw support scores were computed along with the resultant power to detect a true effect. Results. Neither averaged total functional support nor averaged affect and affirmation scores decreased as sample size increased. However, averaged aid scores did decrease as network size increased. Power also increased markedly in all averaged versus raw scores except in averaged aid scores. Discussion and Conclusions. Use of averaged aid scores is not recommended. Use of all other averaged scores appears acceptable. PMID:22007323

Methamphetamine and paranoia: the methamphetamine experience questionnaire.  

PubMed

Paranoia in methamphetamine (MA) users is not well characterized or understood. To investigate this phenomenon, we created the Methamphetamine Experience Questionnaire (MEQ), and tested its reliability and validity in assessing MA-induced paranoia. We administered the MEQ to 274 MA-dependent subjects. Of the total subjects, 45% (123) first experienced paranoia with MA use; 55% did not. Obtaining or using a weapon while paranoid was common (37% and 11% of subjects with MA-induced paranoia, respectively). Test-retest and inter-rater reliability for MA-induced paranoia showed substantial agreement (kappa = .77, p < .05 and kappa = .80, p < .05, respectively). First episodes of paranoia occurred more often with intravenous use of MA, and subsequent episodes at higher doses. There was modest correlation between paranoia on the MEQ and the Brief Symptom Inventory (BSI) paranoid ideation scale (rho = .27, p < .05). As expected, there was a poor correlation between paranoia on the MEQ and the BSI depression scale (rho = .14, p = .07). The MEQ provides useful information on drug use variables that contribute to paranoia commonly associated with MA use. (Am J Addict 2010;00:1-14). PMID:20163388

Are treatment benefits in neuropathic pain reflected in the self assessment of treatment questionnaire?  

PubMed Central

Background/objective The Self Assessment of Treatment (SAT) questionnaire was developed to reflect key patient reported outcomes of Neuropathic Pain (NP) treatments. This study aimed to understand how patients perceived the relevance and ease of understanding of the questions in the SAT and to recommend modifications based on patient and clinician interviews. Methods Semi-structured interviews were conducted with clinicians and NP patients to provide information regarding treatment attributes and the impact of pain. Patients were debriefed on the SAT, a 5-item scale evaluating pain, activity level, quality of life (QoL) and satisfaction with treatment (recommend treatment and undergo treatment again). The SAT has a recall period reflecting back to the start of treatment. The qualitative analysis software ATLAS.ti 5.0 was used to analyze patient transcripts. Changes to the SAT were integrated into the questionnaire for a second round of debriefing interviews. Results Three NP clinicians and 44 patients (20 painful diabetic neuropathy, 16 HIV-associated neuropathy and 8 post herpetic neuralgia) with a mean age of 60.3 (12.3) years and an even gender distribution were interviewed. Patient treatment experience included anticonvulsants (73%), antidepressants (34%), opioids (25%), and topical medications (41%). Pain descriptors and treatment attributes were similar across the three NP groups. Pain relief was judged the most important treatment attribute, followed by ability to undertake activities. Sleep improvement was another important attribute. Activity limitations and QOL were perceived as too broad and non-specific, and were split into 3 concepts each (activity limitations was split into self care, daily and physical activities and QOL was split into sleep, emotions, and social function). A 7-day recall period was introduced. The item stem and response options were made consistent, and a baseline and follow-up questionnaires were developed (except for the satisfaction items) to enable monitoring onset of treatment benefit and change over time. Conclusions The content validity of the revised SAT was improved by the qualitative research, and NP treatment benefits are reflected in a more consistent fashion by the changes. Baseline and follow-up versions make it possible to perform assessments of change over time. PMID:23332037

The effect of an internet option and single-sided printing format to increase the response rate to a population-based study: a randomized controlled trial  

PubMed Central

Background Paper questionnaires are a common means to collect self-reported information in population-based epidemiological studies. Over the past decades, the response rates to epidemiological studies have been decreasing which can affect the selection process of eligible subjects and lead to non-response bias. Hence, research into strategies to increase questionnaire response rates is crucial. The aim of this study was therefore to explore the effectiveness of single-sided questionnaires and an internet option for response in increasing response rates to a population-based study. Methods A 2×2 factorial experiment was embedded within a large population-based study of pain and pain management. Persons in the study sample were 4600 residents in Grampian (north of Scotland) aged 25 years and over who were randomly selected from health board records. Sampled persons were randomly assigned to either receive a single-sided or double-sided questionnaire with or without an internet option to respond. The study questionnaire was distributed via post. Results The overall study response rate was 36.3%. When compared to the reference group that received no intervention (response rate?=?35.5%), the response rate changed only marginally when single-sided questionnaires were distributed (35.8%) or when an option to reply via the internet was provided (34.3%). A somewhat higher increase in response rates was achieved when both strategies were employed (39.6%). Overall, no significant effect on response rate was determined for each strategy or their interaction. Conclusions Evidence from this study suggests that neither single-sided questionnaires nor the option to reply via the internet resulted in a significant increase in response rates to population-based studies.

Cropland responses to extreme winter temperature events: results from a manipulation experiment in north-eastern Italy  

NASA Astrophysics Data System (ADS)

In the last years, several studies has focused on terrestrial ecosystem response to climate warming. Most of them have been conducted on natural ecosystems (forests or grasslands), but few have considered intensively managed ecosystems such as croplands despite of their global extension. In particular, extreme events, such as temperature changes outside the growing season (winter) when soil is not covered by plants, can have a strong impact on soil respiration, residues decomposition, yield and overall net biome production (NBP). In this study, we investigated the response of soil respiration (total and heterotrophic), aboveground NPP, yield and NBP on a soybean crop (Glycine max (L.) Merr.) due to a manipulated warmer or cooler winter. The experiment was carried out in Beano (46°00' N 13°01'E, Italy). Soil albedo and soil temperature were manipulated by covering soil surface during late winter with a layer of inert ceramized silica gravel. We tested three treatments with three replicates each: cooling (Co; white gravel), warming (W; black gravel), mix (M; black and white 4:1 gravel) and control (C; bare soil). An automated soil respiration system measured continuously total soil CO2 efflux across all the year and heterotrophic respiration after sowing in root exclusion subplots. Additionally, soil temperature profiles (0, 2.5, 5 and 10 cm depth), soil water content (between 5 and 10 cm depth) were monitored in each plot. After sowing, soybean phenological phases were periodically assessed and final yield was measured in each plot. Results showed a significant change in upper soil temperature between gravel application and canopy closure (maximum of + 5.8 °C and - 6.8 °C in the warming and cooling treatments, respectively). However, warming had only a transient effect on soil respiration (increase) before sowing. Thereafter, as soon as fresh organic matter availability decreased, soil respiration rate decreased and annual budget was not significantly different from control. On the other hand, cooling showed an annual lower soil respiration in comparison to other treatments. Thus, these results highlight the higher sensitivity of fresh organic matter to extreme and short heat waves. We also observed an anticipation in seed germination in both W and M in comparison to C (-4 days) and a delayed germination (+3 days) in Co. Moreover, seed germination, plant density and growth were increased in W and M and reduced in Co.

In the last years, several studies has focused on terrestrial ecosystem response to climate warming. Most of them have been conducted on natural ecosystems (forests or grasslands), but few have considered intensively managed ecosystems such as croplands despite of their global extension. In particular, extreme events, such as temperature changes outside the growing season (winter) when soil is not covered by plants, can have a strong impact on soil respiration, residues decomposition, yield and overall net biome production (NBP). In this study, we investigated the response of soil respiration (total and heterotrophic), aboveground NPP, yield and NBP on a soybean crop (Glycine max (L.) Merr.) due to a manipulated warmer or cooler winter. The experiment was carried out in Beano (46°00' N 13°01'E, Italy). Soil albedo and soil temperature were manipulated by covering soil surface during late winter with a layer of inert ceramized silica gravel. We tested three treatments with three replicates each: cooling (Co; white gravel), warming (W; black gravel), mix (M; black and white 4:1 gravel) and control (C; bare soil). An automated soil respiration system measured continuously total soil CO2 efflux across all the year and heterotrophic respiration after sowing in root exclusion subplots. Additionally, soil temperature profiles (0, 2.5, 5 and 10 cm depth), soil water content (between 5 and 10 cm depth) were monitored in each plot. After sowing, soybean phenological phases were periodically assessed and final yield was measured in each plot. Preliminary results showed a significant change in upper soil temperature between gravel application and canopy closure (maximum of + 5.8 °C and - 6.8 °C in the warming and cooling treatments, respectively). However, warming had only a transient effect on soil respiration (increase) before sowing. Thereafter, as soon as fresh organic matter availability decreased, soil respiration rate decreased and annual budget was not significantly different from control. On the other hand, cooling showed an annual lower soil respiration in comparison to other treatments. Thus, these results highlight the higher sensitivity of fresh organic matter to extreme and short heat waves. We also observed an anticipation in seed germination in both W and M in comparison to C (-4 days) and a delayed germination (+3 days) in Co. Moreover, seed germination, plant density and growth were increased in W and M and reduced in Co.

Multiple whole bacterial antigens in polyvalent vaccine may result in inhibition of specific responses in rainbow trout (Oncorhynchus mykiss).  

PubMed

The goal of fish vaccination today is to protect fish against multiple bacterial fish pathogens simultaneously using polyvalent vaccines. However, many immunological processes such as antigenic cross-reaction, antigenic competition, affinity maturation and antigen-induced suppression may affect the specificity, avidity and level of antibodies. Consequently, the biological function of antibodies may be markedly different from that predicted by conventional serologic tests. Here, we investigated the effects of vaccination and composition of vaccine on the plasma antibody levels, biological function of antibodies in opsonophagocytosis as well as the effects of vaccination on the blood leucocyte counts. Rainbow trout were vaccinated with saline or with two different polyvalent, mineral oil-adjuvanted vaccines. Vaccine 1 contained Aeromonas salmonicida, Listonella anguillarum and both Th and Fd serotypes of Flavobacterium psychrophilum antigens and vaccine 2 contained A. salmonicida, L. anguillarum and only Fd serotype of Fl. psychrophilum. The antibody-mediated opsonophagocytosis was determined as the respiratory burst (RB) activity of blood monocytes and granulocytes against the tested bacterial antigens. Three weeks after vaccination both vaccine groups and the control group showed increased RB activity against all bacterial strains. However, the increase in RB activities was non-specific and originated from the increased number of circulating granulocytes and monocytes. On the other hand, at 6 weeks post-vaccination both specific antibodies and antibody-dependent opsonophagocytosis appeared in both vaccine groups. However, the composition of the vaccine had a marked effect on the magnitude of specific responses. The Fd+Th vaccine enhanced the target specific opsonophagocytosis, to a lesser extent than the Fd vaccine. Both polyvalent vaccines appeared to mainly affect the numbers of circulating monocytes and our results suggest that the monocytes play a more significant role than the granulocytes in antibody-dependent opsonophagocytosis. Our results also suggest that the presented opsonophagocytic assay is an advantageous method to predict vaccine efficiency and that the number, and properties, of bacterial antigens in polyvalent vaccines should be carefully selected in order to avoid inhibitory effects of antigens on the specific response of fish.

Mechanical Disruption of Tumors by Iron Particles and Magnetic Field Application Results in Increased Anti-Tumor Immune Responses  

PubMed Central

The primary tumor represents a potential source of antigens for priming immune responses for disseminated disease. Current means of debulking tumors involves the use of cytoreductive conditioning that impairs immune cells or removal by surgery. We hypothesized that activation of the immune system could occur through the localized release of tumor antigens and induction of tumor death due to physical disruption of tumor architecture and destruction of the primary tumor in situ. This was accomplished by intratumor injection of magneto-rheological fluid (MRF) consisting of iron microparticles, in Balb/c mice bearing orthotopic 4T1 breast cancer, followed by local application of a magnetic field resulting in immediate coalescence of the particles, tumor cell death, slower growth of primary tumors as well as decreased tumor progression in distant sites and metastatic spread. This treatment was associated with increased activation of DCs in the draining lymph nodes and recruitment of both DCs and CD8(+)T cells to the tumor. The particles remained within the tumor and no toxicities were observed. The immune induction observed was significantly greater compared to cryoablation. Further anti-tumor effects were observed when MRF/magnet therapy was combined with systemic low dose immunotherapy. Thus, mechanical disruption of the primary tumor with MRF/magnetic field application represents a novel means to induce systemic immune activation in cancer. PMID:23133545

Chemical treatment response to variations in non-point pollution water quality: Results of a factorial design experiment.  

PubMed

Chemical treatment of non-point derived pollution often suffers from undesirable oscillations in purification efficiency due to variations in runoff water quality. This study examined the response of the chemical purification process to variations in water quality using a 2(k) factorial design for runoff water rich in humic substances. The four k factors evaluated and the levels applied were: organic matter as dissolved organic carbon (DOC) (20-70 mg/L), suspended solids (SS) (10-60 mg/L), initial water pH (4.5-7), and applied coagulant dosage (ferric sulphate) (35-100 mg/L). Indicators of purification efficiency were residual concentration of DOC, SS and total phosphorus (tot-P). Analysis of variance and factor effect calculations showed that the initial DOC concentration in raw water samples and its interactions with the coagulant dosage applied exerted the most significant influence on the chemical purification process, substantially affecting the residual concentration of DOC, SS and tot-P. The variations applied to the factors SS and pH only slightly affected purification efficiency. The results can be used in the design of purification systems with high organic matter load variation, e.g. peat extraction runoff. PMID:25485936

Atmosphere-Ionosphere Response to the M9 Tohoku Earthquake Revealed by Joined Satellite and Ground Observations. Preliminary Results  

NASA Technical Reports Server (NTRS)

The recent M9 Tohoku Japan earthquake of March 11, 2011 was the largest recorded earthquake ever to hit this nation. We retrospectively analyzed the temporal and spatial variations of four different physical parameters - outgoing long wave radiation (OLR), GPS/TEC, Low-Earth orbit tomography and critical frequency foF2. These changes characterize the state of the atmosphere and ionosphere several days before the onset of this earthquake. Our first results show that on March 8th a rapid increase of emitted infrared radiation was observed from the satellite data and an anomaly developed near the epicenter. The GPS/TEC data indicate an increase and variation in electron density reaching a maximum value on March 8. Starting on this day in the lower ionospheric there was also confirmed an abnormal TEC variation over the epicenter. From March 3-11 a large increase in electron concentration was recorded at all four Japanese ground based ionosondes, which return to normal after the main earthquake. We found a positive correlation between the atmospheric and ionospheric anomalies and the Tohoku earthquake. This study may lead to a better understanding of the response of the atmosphere/ionosphere to the Great Tohoku earthquake.

The feeding practices and structure questionnaire: construction and initial validation in a sample of Australian first-time mothers and their 2-year olds  

PubMed Central

Background Early feeding practices lay the foundation for children’s eating habits and weight gain. Questionnaires are available to assess parental feeding but overlapping and inconsistent items, subscales and terminology limit conceptual clarity and between study comparisons. Our aim was to consolidate a range of existing items into a parsimonious and conceptually robust questionnaire for assessing feeding practices with very young children (<3 years). Methods Data were from 462 mothers and children (age 21–27 months) from the NOURISH trial. Items from five questionnaires and two study-specific items were submitted to a priori item selection, allocation and verification, before theoretically-derived factors were tested using Confirmatory Factor Analysis. Construct validity of the new factors was examined by correlating these with child eating behaviours and weight. Results Following expert review 10 factors were specified. Of these, 9 factors (40 items) showed acceptable model fit and internal reliability (Cronbach’s ?: 0.61-0.89). Four factors reflected non-responsive feeding practices: ‘Distrust in Appetite’, ‘Reward for Behaviour’, ‘Reward for Eating’, and ‘Persuasive Feeding’. Five factors reflected structure of the meal environment and limits: ‘Structured Meal Setting’, ‘Structured Meal Timing’, ‘Family Meal Setting’, ‘Overt Restriction’ and ‘Covert Restriction’. Feeding practices generally showed the expected pattern of associations with child eating behaviours but none with weight. Conclusion The Feeding Practices and Structure Questionnaire (FPSQ) provides a new reliable and valid measure of parental feeding practices, specifically maternal responsiveness to children’s hunger/satiety signals facilitated by routine and structure in feeding. Further validation in more diverse samples is required. PMID:24898364

Hydraulic and topographic response of sand-bed rivers to woody riparian seedlings: field-scale laboratory methods and results  

NASA Astrophysics Data System (ADS)

Feedbacks between topography, flow fields and vegetation community structure are fundamental processes in many rivers. In addition, predicting seedling mortality in response to flood events requires a detailed understanding of the influence of flow on seedling scour and burial. As of yet, however, flow and sediment transport in the presence of seedlings are poorly understood. Measurements quantifying the response of topography and flow to the presence of seedlings with differing plant architectures were obtained within a field-scale meandering stream channel with a mobile sand bed (median grain size of 0.7 mm) and full experimental control over sediment and water discharge. Seedlings of Tamarix spp. (tamarisk) and Populus fremontii (cottonwood) with intact roots were installed on a point bar during low flow conditions. Flow rate was then elevated to a constant flood level, while sediment feed rate, plant density, and plant species were varied during each of eight different experimental runs. Flood conditions were maintained long enough for bar topography to reach steady state. The presence of all types of vegetation on the bar decreased the height and lateral extent of dunes migrating across the bar, thereby preventing the development of dunes as the primary mechanism of sediment transport through the bend. Time-averaged bar volume increased from bare-bed conditions when sparse tamarisk, dense tamarisk, or mixed cottonwood and tamarisk seedlings were present on the bar. The presence of dense cottonwood seedlings, however, did not result in an increase in either bar size or height, likely because an increase in steady-state turbulence intensities on the bar when dense cottonwood was present interfered with sediment deposition. Thus, differing plant architecture was an important influence on topographic evolution. In particular, it is possible that the flexibility of tamarisk seedlings causes them to behave analogously to herbaceous vegetation, sheltering the bar surface from turbulent eddies and encouraging deposition. Relationships for the influence of vegetation density and architecture on shear stress and sediment transport are suitable for incorporation into 2-D hydraulic and sediment transport models.

Development of a self-administered questionnaire to screen patients for cervical myelopathy  

PubMed Central

Background In primary care, it is often difficult to diagnose cervical myelopathy. However, a delay in treatment could cause irreversible aftereffects. With a brief and effective self-administered questionnaire for cervical myelopathy, cervical myelopathy may be screened more easily and oversight may be avoided. As there is presently no screening tool for cervical myelopathy, the aim of this study was to develop a self-administered questionnaire for the screening of cervical myelopathy. Methods A case-control study was performed with the following two groups at our university hospital from February 2006 to September 2008. Sixty-two patients (48 men, 14 women) with cervical myelopathy who underwent operative treatment were included in the myelopathy group. In the control group, 49 patients (20 men, 29 women) with symptoms that could be distinguished from those of cervical myelopathy, such as numbness, pain in the upper extremities, and manual clumsiness, were included. The underlying conditions were diagnosed as carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, tarsal tunnel syndrome, diabetes mellitus neuropathy, cervical radiculopathy, and neuralgic amyotrophy. Twenty items for a questionnaire in this study were chosen from the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire, which is a new self-administered questionnaire, as an outcome measure for patients with cervical myelopathy. Data were analyzed by univariate analysis using the chi-square test and by multiple logistic regression analysis. According to the resulting odds ratio, ?-coefficients, and p value, items were chosen and assigned a score. Results Eight items were chosen by univariate and multiple logistic regression analyses and assigned a score. The Hosmer-Lemeshow statistic showed p = 0.805. The area under the receiver operation characteristic curve was 0.86. The developed questionnaire had a sensitivity of 93.5% and a specificity of 67.3%. Conclusions We successfully developed a simple self-administered questionnaire to screen for cervical myelopathy. PMID:21092213

Quantifying the response of terrestrial carbon fluxes to future climate change: Results from CMIP5 Earth System Models simulations  

NASA Astrophysics Data System (ADS)

Quantification of the terrestrial ecosystem feedback is crucial for better prediction of future global climate-carbon cycle. However, previous studies using coupled climate-carbon models show large uncertainties of terrestrial carbon-climate feedbacks. While the largest uncertainty in feedbacks is induced by the models' responses to radiative and physiological CO2, recent studies demonstrate that the N cycle and land cover change could have significant impacts. Here, we explore the responses of carbon fluxes between atmosphere and land to various forcing using five experiments (i.e., historical, RCP45, RCP85, esmFdbk2, esmFixClim2) from 14 CMIP5 Earth System Models (ESMs). The simulated modern global net primary productivity (NPP) ranges from 46.1 Pg C yr-1 in CCSM4 to 90.8 Pg C yr-1 in MPI-ESM-LR, with an ensemble mean of 68.6 Pg C yr-1. Eleven of the fourteen ESMs substantially overestimate current global NPP as calculated from MOD17A3 dataset (53.5 ± 1.7 Pg C yr-1). All models predicted an increase of global NPP in both RCP concentration scenarios. With N limitation, CCSM4 and NorESM1-M simulated the lowest current NPP and future relative increase of NPP in RCP concentration scenarios. A comparison of the coupled and uncoupled CO2-climate experiments indicates that while the increase of NPP north of 45°N is a combined effect of CO2 fertilization and global warming, the increase of global NPP in the RCP4.5 concentration scenario is dominated by CO2 fertilization. In general, the magnitude of NPP increases caused by CO2-induced warming and/or CO2-fertilization in each model is significantly correlated with its simulated modern NPP value. Similar to NPP, the increase of terrestrial heterotrophic respiration carbon fluxes (RH) and fire emission carbon fluxes (fFire) in RCP concentration scenarios are tightly correlated with their modern intensity among the CMIP5 ESMs. Consequently, the simulated response of net ecosystem productivity (NEP = NPP - RH - fFire) in RCP scenarios is correlated with its modern magnitude. Despite different magnitudes, all ESMs predict that the land acts as a sink of carbon in both RCP scenarios without land cover change. In contrast, when including land cover change, two and five ESMs suggest that the land will become a source of carbon with the RCP4.5 and RCP8.5 scenarios, respectively. Thus, future land cover change, which is very uncertain, is consistently predicted to contribute significantly to the terrestrial carbon-climate feedback. In sum, our results suggest that (1) an accurate representation of the modern terrestrial carbon fluxes is critical to constrain future carbon-climate feedbacks and (2) in addition to CO2-fertilization and CO2-induced warming, the N cycle and land cover change are important for predicting future carbon-climate interactions.

Health status in patients with coexistent COPD and heart failure: a validation and comparison between the Clinical COPD Questionnaire and the Minnesota Living with Heart Failure Questionnaire  

PubMed Central

Background Chronic obstructive pulmonary disease (COPD) and heart failure (HF) are both common diseases that coexist frequently. Patients with both diseases have worse stable state health status when compared with patients with one of these diseases. In many outpatient clinics, health status is monitored routinely in COPD patients using the Clinical COPD Questionnaire (CCQ) and in HF patients with the Minnesota Living with Heart Failure Questionnaire (MLHF-Q). This study validated and compared which questionnaire, ie, the CCQ or the MLHF-Q, is suited best for patients with coexistent COPD and HF. Methods Patients with both COPD and HF and aged ?40 years were included. Construct validity, internal consistency, test–retest reliability, and agreement were determined. The Short-Form 36 was used as the external criterion. All questionnaires were completed at baseline. The CCQ and MLHF-Q were repeated after 2 weeks, together with a global rating of change. Results Fifty-eight patients were included, of whom 50 completed the study. Construct validity was acceptable. Internal consistency was adequate for CCQ and MLHF-Q total and domain scores, with a Cronbach’s alpha ?0.70. Reliability was adequate for MLHF-Q and CCQ total and domain scores, and intraclass correlation coefficients were 0.70–0.90, except for the CCQ symptom score (intraclass correlation coefficient 0.42). The standard error of measurement on the group level was smaller than the minimal clinical important difference for both questionnaires. However, the standard error of measurement on the individual level was larger than the minimal clinical important difference. Agreement was acceptable on the group level and limited on the individual level. Conclusion CCQ and MLHF-Q were both valid and reliable questionnaires for assessment of health status in patients with coexistent COPD and HF on the group level, and hence for research. However, in clinical practice, on the individual level, the characteristics of both questionnaires were not as good. There is room for a questionnaire with good evaluative properties on the individual level, preferably tested in a setting of patients with COPD or HF, or both. PMID:25285000

The Sensory Perception Quotient (SPQ): development and validation of a new sensory questionnaire for adults with and without autism  

PubMed Central

Background Questionnaire-based studies suggest atypical sensory perception in over 90% of individuals with autism spectrum conditions (ASC). Sensory questionnaire-based studies in ASC mainly record parental reports of their child’s sensory experience; less is known about sensory reactivity in adults with ASC. Given the DSM-5 criteria for ASC now include sensory reactivity, there is a need for an adult questionnaire investigating basic sensory functioning. We aimed to develop and validate the Sensory Perception Quotient (SPQ), which assesses basic sensory hyper- and hyposensitivity across all five modalities. Methods A total of 359 adults with (n?=?196) and without (n?=?163) ASC were asked to fill in the SPQ, the Sensory Over-Responsivity Inventory (SensOR) and the Autism-Spectrum Quotient (AQ) online.

Brazilian Portuguese Validated Version of the Cardiac Anxiety Questionnaire  

PubMed Central

Background Cardiac Anxiety (CA) is the fear of cardiac sensations, characterized by recurrent anxiety symptoms, in patients with or without cardiovascular disease. The Cardiac Anxiety Questionnaire (CAQ) is a tool to assess CA, already adapted but not validated to Portuguese. Objective This paper presents the three phases of the validation studies of the Brazilian CAQ. Methods To extract the factor structure and assess the reliability of the CAQ (phase 1), 98 patients with coronary artery disease were recruited. The aim of phase 2 was to explore the convergent and divergent validity. Fifty-six patients completed the CAQ, along with the Body Sensations Questionnaire (BSQ) and the Social Phobia Inventory (SPIN). To determine the discriminative validity (phase 3), we compared the CAQ scores of two subgroups formed with patients from phase 1 (n = 98), according to the diagnoses of panic disorder and agoraphobia, obtained with the MINI - Mini International Neuropsychiatric Interview. Results A 2-factor solution was the most interpretable (46.4% of the variance). Subscales were named "Fear and Hypervigilance" (n = 9; alpha = 0.88), and "Avoidance", (n = 5; alpha = 0.82). Significant correlation was found between factor 1 and the BSQ total score (p < 0.01), but not with factor 2. SPIN factors showed significant correlations with CAQ subscales (p < 0.01). In phase 3, "Cardiac with panic" patients scored significantly higher in CAQ factor 1 (t = -3.42; p < 0.01, CI = -1.02 to -0.27), and higher, but not significantly different, in factor 2 (t = -1.98; p = 0.51, CI = -0.87 to 0.00). Conclusions These results provide a definite Brazilian validated version of the CAQ, adequate to clinical and research settings. PMID:24145391

Research: Care Delivery Development and validation of the Diabetes Medication System Rating Questionnaire-Short Form  

PubMed Central

Aims To develop and validate a short form of the 54-item Diabetes Medication System Rating Questionnaire that maintains the domains and performance characteristics of the long-form questionnaire. Methods Data from the Diabetes Medication System Rating Questionnaire validation study were analysed to select items representing the nine scales (convenience, negative events, interference, self-monitoring of blood glucose burden, efficacy, social burden, psychological well-being, treatment satisfaction and treatment preference). The resulting 20-item Diabetes Medication System Rating Questionnaire Short-Form was administered online, with validated criterion measures of treatment satisfaction and medication adherence, with a retest within 2 weeks. Participants were US adults (N = 413) with Type 2 diabetes using oral agents alone; insulin by syringe and/or pen with or without oral agents; or glucagon-like peptide-1 agents. Most participants (82%) completed the retest. Results The median inter-item agreement of scales was 0.76 and the total composite (mean of all items except treatment preference) was 0.88. The median test-retest reliability of scales was 0.86, and of the total composite was 0.95. All statistically significant correlations between Diabetes Medication System Rating Questionnaire Short-Form scales and criterion measures of treatment satisfaction and adherence were in the expected direction. The median correlation of the Diabetes Medication System Rating Questionnaire Short-Form with corresponding criterion measures of treatment satisfaction was 0.59; the mean correlation of the same Diabetes Medication System Rating Questionnaire Short-Form measures with adherence was 0.42. The Diabetes Medication System Rating Questionnaire Short-Form scales were more powerful predictors of adherence than were the criterion measures of treatment satisfaction. The Diabetes Medication System Rating Questionnaire Short-Form scales differentiated between those taking different medications and between those using different insulin delivery devices. Conclusions This study suggests that the Diabetes Medication System Rating Questionnaire Short-Form provides a comprehensive set of measures with acceptable reliability and validity and a reduced burden of administration. What’s new? This study reports the development and validation of a short form of the Diabetes Medication System Rating Questionnaire (DMSRQ) that maintains the domains and performance of the long-form questionnaire. Like the Diabetes Medication System Rating Questionnaire, the Diabetes Medication System Rating Questionnaire-Short Form (DMSRQ-SF) has good reliability and enhanced validity relative to other comparable measures. The DMSRQ-SF has a lower burden of administration than the DMSRQ, which makes it suitable for use in clinical settings as well as research. Each of the DMSRQ-SF therapy perception items was chosen to have unique validity and applicability as a single-item measure, i.e. to assess an independent aspect of treatment satisfaction that discriminates treatments and drives global assessments of treatments.

Interpretation of the Sexual Functioning Questionnaire in the Presence of Vulvar Pain  

PubMed Central

Objective To assess whether the domains identified by items on the Sexual Functioning Questionnaire (SFQ) apply to women with vulvodynia. Study Design Forty-one women with vulvodynia and 43 asymptomatic controls, between the ages 18–70 years, were assessed with a physician evaluation and a written survey that included the SFQ. Results Women with vulvodynia had a higher likelihood of female sexual dysfunction (FSD) than did controls as indicated by five of the seven individual SFQ domains (desire, arousal-lubrication, pain, enjoyment, and partner domains, p<0.05). Scored on individual items relating to pain or penetrative sex differed more by vulvodynia presence than did items related to arousal and emotions. Compared to published SFQ psychometrics, factor analysis among women with vulvodynia demonstrated similar factor loadings in 6 of the 7 domains of the SFQ (desire, arousal-sensation, arousal-lubrication, orgasm, partner, and pain), but the enjoyment domain intermingled substantially with these other domains. Conclusions The SFQ factor structure is generally valid among women with vulvodynia. However, vulvodynia may impact responses to individual items on questions about pain and/or penetration, which may potentially result in erroneous interpretations. PMID:23595036

Generic questionnaires of QoL do not address all the especial features of ALS and therefore translation and validation of disease specific questionnaires such as Amyotrophic Lateral Sclerosis Assessment Questionnaire 40-item (ALSAQ-40) is necessary for assessment of patients with different languages. The aim of this study was to review the validation of the Persian version of the ALSAQ-40. Methods Meticulously translated ALSAQ-40 was completed by 21 ALS patients. Internal reliability was evaluated using Cronbach's alpha coefficient and item-total correlation was also used to evaluate the correlation of each question with total score. Validity was evaluated through comparison with Amyotrophic Lateral Sclerosis Functional Rating Scale-revised (ALSFRS-r) and the 36-Item Short Form Health Survey (SF-36). Results Cronbach's alpha coefficient was 0.91-0.96 for different scales of the ALSAQ-40. All the 40 questions of the questionnaire had correlation greater than 0.5. Correlation coefficient of all the related scales of the Persian version of ALSAQ-40, SF-36 and ALSFRS-r was greater than 0.59 with P value < 0.001. Conclusion Measures of the Cronbach's alpha coefficient and item-total correlation demonstrated reliability and consistency of the questionnaire, and correlation coefficients confirmed the validity of different items in the questionnaire. This study showed that the Persian version of the ALSAQ-40 is a reliable and valid questionnaire for the evaluation of QoL in ALS patients with Persian language. PMID:24250914

Investigation of Multiple Imputation in Low-Quality Questionnaire Data  

ERIC Educational Resources Information Center

The performance of multiple imputation in questionnaire data has been studied in various simulation studies. However, in practice, questionnaire data are usually more complex than simulated data. For example, items may be counterindicative or may have unacceptably low factor loadings on every subscale, or completely missing subscales may…
