    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

    Background The new Global Obstructive Lung Disease (GOLD) guidelines advice to focus treatment in Chronic Obstructive Pulmonary Disease (COPD) on improvement of functional state, prevention of disease progression and minimization of symptoms. So far no validated questionnaires are available to measure symptom and functional state in daily clinical practice. The aim of this study was to develop and validate the Clinical COPD Questionnaire (CCQ). Methods Qualitative research with patients and clinicians was performed to generate possible items to evaluate clinical COPD control. Thereafter, an item reduction questionnaire was sent to 77 international experts. Sixty-seven experts responded and the 10 most important items, divided into 3 domains (symptoms, functional and mental state) were included in the CCQ (scale: 0 = best, 6 = worst). Results Cross-sectional data were collected from 119 subjects (57 COPD, GOLD stage I-III; 18 GOLD stage 0 and 44 (ex)smokers). Cronbach's ? was high (0.91). The CCQ scores in patients (GOLD 0-III) were significantly higher than in healthy (ex)smokers. Furthermore, significant correlations were found between the CCQ total score and domains of the SF-36 (? = 0.48 to ? = 0.69) and the SGRQ (? = 0.67 to ? = 0.72). In patients with COPD, the correlation between the CCQ and FEV1%pred was ? =-0.49. Test-retest reliability was determined in 20 subjects in a 2-week interval (Intra Class Coefficient = 0.94). Thirty-six smokers with and without COPD showed significant improvement in the CCQ after 2 months smoking cessation, indicating the responsiveness of the CCQ. Conclusion The CCQ is a self-administered questionnaire specially developed to measure clinical control in patients with COPD. Data support the validity, reliability and responsiveness of this short and easy to administer questionnaire. PMID:12773199

  13. Designing questionnaires: healthcare survey to compare two different response scales

    2014-01-01

    Background A widely discussed design issue in patient satisfaction questionnaires is the optimal length and labelling of the answering scale. The aim of the present study was to compare intra-individually the answers on two response scales to five general questions evaluating patients’ perception of hospital care. Methods Between November 2011 and January 2012, all in-hospital patients at a Swiss University Hospital received a patient satisfaction questionnaire on an adjectival scale with three to four labelled categories (LS) and five redundant questions displayed on an 11-point end-anchored numeric scale (NS). The scales were compared concerning ceiling effect, internal consistency (Cronbach’s alpha), individual item answers (Spearman’s rank correlation), and concerning overall satisfaction by calculating an overall percentage score (sum of all answers related to the maximum possible sum). Results The response rate was 41% (2957/7158), of which 2400 (81%) completely filled out all questions. Baseline characteristics of the responders and non-responders were similar. Floor and ceiling effect were high on both response scales, but more pronounced on the LS than on the NS. Cronbach’s alpha was higher on the NS than on the LS. There was a strong individual item correlation between both answering scales in questions regarding the intent to return, quality of treatment and the judgement whether the patient was treated with respect and dignity, but a lower correlation concerning satisfactory information transfer by physicians or nurses, where only three categories were available in the LS. The overall percentage score showed a comparable distribution, but with a wider spread of lower satisfaction in the NS. Conclusions Since the longer scale did not substantially reduce the ceiling effect, the type of questions rather than the type of answering scale could be addressed with a focus on specific questions about concrete situations instead of general questions. Moreover, the low correlation in questions about information provision suggests that only three possible response choices are insufficient. Further investigations are needed to find a more sensitive scale discriminating high-end ratings. Otherwise, a longitudinal within-hospital or a cross-sectional between-hospital comparison of patient care is questionable. PMID:25086869

    Background Data for health surveys are often collected using either mailed questionnaires, telephone interviews or a combination. Mode of data collection can affect the propensity to refuse to respond and result in different patterns of responses. The objective of this paper is to examine and quantify effects of mode of data collection in health surveys. Methods A stratified sample of 4,000 adults residing in Denmark was randomised to mailed questionnaires or computer-assisted telephone interviews. 45 health-related items were analyzed; four concerning behaviour and 41 concerning self assessment. Odds ratios for more positive answers and more frequent use of extreme response categories (both positive and negative) among telephone respondents compared to questionnaire respondents were estimated. Tests were Bonferroni corrected. Results For the four health behaviour items there were no significant differences in the response patterns. For 32 of the 41 health self assessment items the response pattern was statistically significantly different and extreme response categories were used more frequently among telephone respondents (Median estimated odds ratio: 1.67). For a majority of these mode sensitive items (26/32), a more positive reporting was observed among telephone respondents (Median estimated odds ratio: 1.73). The overall response rate was similar among persons randomly assigned to questionnaires (58.1%) and to telephone interviews (56.2%). A differential nonresponse bias for age and gender was observed. The rate of missing responses was higher for questionnaires (0.73 – 6.00%) than for telephone interviews (0 – 0.51%). The "don't know" option was used more often by mail respondents (10 – 24%) than by telephone respondents (2 – 4%). Conclusion The mode of data collection affects the reporting of self assessed health items substantially. In epidemiological studies, the method effect may be as large as the effects under investigation. Caution is needed when comparing prevalences across surveys or when studying time trends.

    OBJECTIVES. Low response rates to voluntary surveys raise questions about how representative the responses are. We compared the behavior and attitudes of responders, willing and reluctant, and nonresponders to anonymous questionnaires about behaviors that might expose participants to the human immunodeficiency virus (HIV). METHODS. Questionnaires were sent to 1080 Danish adults 18 through 59 years including explicit questions about sexual acts and illegal drug use. Identical questionnaires were sent to 3600 other Danes, similarly chosen; packets sent to these persons included cards to be returned separately informing us that they had responded. Questionnaires were sent twice more to nonresponders, who, if they then responded, were considered reluctant responders. One hundred nonresponders were telephoned and asked why they had refused to respond. RESULTS. Enclosing return cards did not affect initial response rate, but prompting boosted replies from 52% to 73%. However, behaviors were generally similar among initial and reluctant responders. One third of nonresponders agreed to respond if we wished (total potential response: 82%). In general, the reasons for nonresponse did not suggest that the life-styles of nonresponders placed them at risk for HIV infection. CONCLUSIONS. This method provides a simple, inexpensive approach to improving response rates and learning about the biases of reluctant responders and nonresponders. PMID:1443301

    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

  18. A confidence interval approach to investigating non-response bias and monitoring response to postal questionnaires.

    STUDY OBJECTIVE--The aim was to develop an alternative method of investigating non-response bias in postal surveys, including a method of calculating a final full (100%) coverage confidence interval which avoids the wide intervals of existing approaches. DESIGN AND SETTING--As part of a two stage survey of disablement in the community, a first phase postal questionnaire was sent to 25,168 households in Calderdale, West Yorkshire, England. Confidence intervals were calculated to investigate the precision of estimates using a "no bias" model, where the prevalence in non-responders is assumed to be the same as in responders. RESPONDENTS--A total of 21,889 postal questionnaires were returned (87%), representing households containing 42,826 people aged 16 years and over. This was achieved by the original post (1st wave, 57% response); two further postal follow ups (2nd and 3rd waves, taking the response to 73% and 81% respectively), the latter including a small personal call back; and a final postal follow up (the 4th wave). RESULTS--The cumulative estimated prevalence of those with dependence was plotted as the survey progressed. The final wave full coverage estimated prevalence for those aged 16-64 years was 12.8 per 1000 with 95% confidence intervals of 11.3-14.4 per 1000. The integrity of this estimate holds as long as the true prevalence in non-responders is within the calculated non-response confidence interval under the no bias assumption, 9.7-16.0 per 1000 people. This latter interval represents the tolerance of prevalence in non-responders implied by the no bias assumption. CONCLUSIONS--The findings have general implications for monitoring non-response bias in postal screening questionnaires. The confidence interval approach developed in this paper offers an alternative to existing regression based estimates, giving an indication of the range of prevalence amongst non-responders that could be tolerated before the no bias assumption used by the model is breached. It is suggested that this approach can be used to determine both the extent of bias, and to aid decision making about the appropriate juncture to terminate follow up. It highlights the potential, particularly in the context of a computerised survey operation, of methodological investigation occurring simultaneously with survey operation. PMID:1828494

    1958-01-01

    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.

  3. Do incentives, reminders or reduced burden improve healthcare professional response rates in postal questionnaires? two randomised controlled trials

    PubMed Central

    2012-01-01

    Background Healthcare professional response rates to postal questionnaires are declining and this may threaten the validity and generalisability of their findings. Methods to improve response rates do incur costs (resources) and increase the cost of research projects. The aim of these randomised controlled trials (RCTs) was to assess whether 1) incentives, 2) type of reminder and/or 3) reduced response burden improve response rates; and to assess the cost implications of such additional effective interventions. Methods Two RCTs were conducted. In RCT A general dental practitioners (dentists) in Scotland were randomised to receive either an incentive; an abridged questionnaire or a full length questionnaire. In RCT B non-responders to a postal questionnaire sent to general medical practitioners (GPs) in the UK were firstly randomised to receive a second full length questionnaire as a reminder or a postcard reminder. Continued non-responders from RCT B were then randomised within their first randomisation to receive a third full length or an abridged questionnaire reminder. The cost-effectiveness of interventions that effectively increased response rates was assessed as a secondary outcome. Results There was no evidence that an incentive (52% versus 43%, Risk Difference (RD) -8.8 (95%CI ?22.5, 4.8); or abridged questionnaire (46% versus 43%, RD ?2.9 (95%CI ?16.5, 10.7); statistically significantly improved dentist response rates compared to a full length questionnaire in RCT A. In RCT B there was no evidence that a full questionnaire reminder statistically significantly improved response rates compared to a postcard reminder (10.4% versus 7.3%, RD 3 (95%CI ?0.1, 6.8). At a second reminder stage, GPs sent the abridged questionnaire responded more often (14.8% versus 7.2%, RD ?7.7 (95%CI ?12.8, -2.6). GPs who received a postcard reminder followed by an abridged questionnaire were most likely to respond (19.8% versus 6.3%, RD 8.1%, and 9.1% for full/postcard/full, three full or full/full/abridged questionnaire respectively). An abridged questionnaire containing fewer questions following a postcard reminder was the only cost-effective strategy for increasing the response rate (£15.99 per response). Conclusions When expecting or facing a low response rate to postal questionnaires, researchers should carefully identify the most efficient way to boost their response rate. In these studies, an abridged questionnaire containing fewer questions following a postcard reminder was the only cost-effective strategy. An increase in response rates may be explained by a combination of the number and type of contacts. Increasing the sampling frame may be more cost-effective than interventions to prompt non-responders. However, this may not strengthen the validity and generalisability of the survey findings and affect the representativeness of the sample. PMID:22891875

    The shortage of future forensic pathologists is a serious problem both in Japan and overseas. In Japan, however, factors such as government budget cuts and increasing the autopsy rates, make the condition even worse. In an attempt to improve this situation, we implemented a questionnaire survey to investigate the particular features necessary when selecting a career in forensic medicine. As a preliminary study, we sent the questionnaire along with an anonymous answer sheet to all forensic pathologists with a degree in medicine M.D., who were affiliated with universities in Hokkaido and the Tohoku district of Japan as of August 2011. Thirteen physicians in nine universities (response rate 77.8%) returned the answer sheet. Characteristics of participants are listed below: years of experience, board specialty and number of years as board certified specialists, percentage of work effort spent on autopsy practice, the time when they decided to work as a forensic pathologist, the time when to best recommend forensic pathologist as a career, and crucial factors in choosing the specialty of forensic medicine. As a result of this research, we've revealed the importance of undergraduate medical education or the effect on the role models. Furthermore, we've also extracted miscellaneous comments, such as standardization of minimum requirements. In our study, we' ve found some clues to increase future candidates in the field forensic medicine. However, we must collect further samples for our questionnaire survey to validate the study, and, as a future project, we must also address this problem at the congress of forensic medicine.

    A postal questionnaire study was carried out in an urban general practice to determine the effect of the introductory letter being sent by the participants' own general practitioner compared with that from a letter sent directly from a research unit. By sequential sampling 409 individuals aged between 40 and 59 were assigned to one of two groups. The people in one group were written to by their own general practitioner and those in the other by a doctor from a research unit. Husbands and wives were paired and were always sent the same letter. A second letter was sent to nonresponders after one month. The response rate to the general practitioner was significantly higher than that to the doctor in the research unit (85% compared with 75%) and differed by age and sex. The results have important implications for other research workers and suggest that general practitioners are in a key position in the conduct of medical and epidemiological research. PMID:3933719

    2015-08-01

    A paper/pencil instrument, adapted from Miller and colleagues' (1991) Helpful Responses Questionnaire (HRQ), was developed to assess clinician skill with core communicative aspects involved in delivering contingency management (CM). The instrument presents a single vignette consisting of six points of client dialogue to which respondents write 'what they would say next.' In the context of an implementation/effectiveness hybrid trial, 19 staff clinicians at an opiate treatment program completed serial training outcome assessments before, following, and three months after CM training. Assessments included this adaptation of the HRQ, a multiple-choice CM knowledge test, and a recorded standardized patient encounter scored for CM skillfulness. Study results reveal promising psychometric properties for the instrument, including strong scoring reliability, internal consistency, concurrent and predictive validity, test-retest reliability and sensitivity to training effects. These preliminary findings suggest the instrument is a viable, practical method to assess clinician skill in communicative aspects of CM delivery. PMID:25770870

    The aim of this study was to determine the responsiveness, Minimal Important Difference (MID) and Minimal Detectable Change (MDC) scores of the shortened Disability Arm Shoulder Hand (QuickDASH) questionnaire. Participants (n = 35) were recruited from private physiotherapy practices. Participants completed the QuickDASH questionnaire on two occasions; the first prior to treatment and the second at discharge or at six weeks post baseline, whichever event occurred first. The participants also completed a Global Change in Status Questionnaire (GSCQ). Responsiveness across treatment to discharge or at six weeks post initial visit was analysed by calculating the Effect Size (ES) and Standardised Response Mean (SRM). The MID was calculated using an anchor based approach and the MDC score was based upon calculations of the standard error of measurement (SEM). The results indicated that responsiveness was high (ES = 1.02, SRM = 1.1). The MID was 19 points while the MDC was 11 points. These results provide evidence that the QuickDASH is a responsive instrument when utilised in patients seen in private practice over a typical treatment interval. PMID:20434942

    A preliminary draft questionnaire concerning community response to sonic booms was developed. Interviews were conducted in two communities that had experienced supersonic overflights of the SR-71 airplane for several years. Even though the overflights had ceased about 6 months prior to the interviews, people clearly remembered hearing sonic booms. A total of 22 people living in central Utah and 23 people living along Idaho/Washington state border took part in these interviews. The draft questionnaire was constantly modified during the study in order to evaluate different versions. Questions were developed which related to annoyance, startle, sleep disturbance, building vibration, and building damage. Based on the data collected, a proposed community response survey response instrument was developed for application in a full-scale sonic boom study.

    Background Improving questionnaire response rates is an everlasting issue for research. Today, the Internet can easily be used to collect data quickly. However, collecting data on the Internet can lead to biased samples because not everyone is able to access or use the Internet. The older population, for example, is much less likely to use the Internet. The Patient-Reported Outcomes Following Initial Treatment and Long-Term Evaluation of Survivorship (PROFILES) registry offers a platform to collect Web-based and paper questionnaires and to try different measures to improve response rates. Objective In this study, our aim was to study the influence of two methods of invitation on the response rate. Our second aim was to examine the preference of questionnaire mode of administration (paper or Web-based) for the older patient in particular. Methods To test these two invitational methods, 3406 colorectal cancer patients between ages 18 and 85 years received an invitation containing an access code for the Web-based questionnaire. They could also request a paper questionnaire with an included reply card (paper-optional group). In contrast, 179 randomly selected colorectal cancer patients received a paper questionnaire with the invitation (paper-included group). They could also choose to fill out the Web-based questionnaire with the included access code. Results Response rates did not differ between the paper-optional and the paper-included groups (73.14%, 2491/3406 and 74.9%, 134/179, P=.57). In the paper-optional group, online response was significantly higher when compared to the paper-included group (41.23%, 1027/2491 vs 12.7%, 17/134, P<.001). The majority of online respondents responded after the first invitation (95.33%, 979/1027), which was significantly higher than the paper respondents (52.19%, 764/1464, P<.001). Respondents aged 70 years and older chose to fill out a paper questionnaire more often (71.0%, 677/954). In the oldest age group (?80 years), 18.2% (61/336) of the respondents filled out a Web-based questionnaire. Conclusions The lack of difference in response rates between invitation modes implies that researchers can leave out a paper questionnaire at invitation without lowering response rates. It may be preferable not to include a paper questionnaire because more respondents then will fill out a Web-based questionnaire, which will lead to faster available data. However, due to respondent preference, it is not likely that paper questionnaires can be left out completely in the near future. PMID:25953059

    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. PMID:25632334

    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).

    Objective Millions of patients suffer from the disabling hand manifestations of rheumatoid arthritis (RA), yet few hand-specific instruments are validated in this population. Our objective is to assess the reliability, validity, and responsiveness of the Michigan Hand Questionnaire (MHQ) in RA patients. Methods At enrollment and at 6 months, 128 RA patients with severe subluxation of the metacarpophalangeal joints completed the MHQ, a 37-item questionnaire with 6 domains: function, activities of daily living (ADL), pain, work, aesthetics, and satisfaction. Reliability was measured using Spearman correlation coefficients (r) between time periods. Internal consistency was measured using Cronbach’s ?. Construct validity was measured by correlating MHQ responses with the Arthritis Impact Measurement Scale 2 (AIMS2). Responsiveness was measured by calculating standardized response means between time periods. Results The MHQ demonstrated good test-retest reliability (r = 0.66, p<0.001). Cronbach’s ? scores were high for ADL (?=0.90), function (?=0.87), aesthetics (?=0.79), and satisfaction (?=0.89), indicating redundancy. The MHQ correlated well with AIMS2 responses. Function (r=?0.63), ADL (r=?0.77), work (r=?0.64), pain (r=0.59), and summary score (r=?0.74) were correlated with the physical domain. Affect was correlated with ADL (r=?0.47), work (r=?0.47), pain (r=0.48), and summary score (r=?0.53). Responsiveness was excellent among arthroplasty patients: function (SRM=1.42), ADL (SRM=0.89), aesthetics (SRM=1.23), satisfaction (SRM=1.76), and summary score (SRM=1.61). Conclusions The MHQ is easily administered, reliable and valid to measure rheumatoid hand function, and can be used to measure outcomes in rheumatoid hand disease. PMID:20521331

    Objectives: Lifetime occupational history (OH) questionnaires often use open-ended questions to capture detailed information about study participants’ jobs. Exposure assessors use this information, along with responses to job- and industry-specific questionnaires, to assign exposure estimates on a job-by-job basis. An alternative approach is to use information from the OH responses and the job- and industry-specific questionnaires to develop programmable decision rules for assigning exposures. As a first step in this process, we developed a systematic approach to extract the free-text OH responses and convert them into standardized variables that represented exposure scenarios. Methods: Our study population comprised 2408 subjects, reporting 11991 jobs, from a case–control study of renal cell carcinoma. Each subject completed a lifetime OH questionnaire that included verbatim responses, for each job, to open-ended questions including job title, main tasks and activities (task), tools and equipment used (tools), and chemicals and materials handled (chemicals). Based on a review of the literature, we identified exposure scenarios (occupations, industries, tasks/tools/chemicals) expected to involve possible exposure to chlorinated solvents, trichloroethylene (TCE) in particular, lead, and cadmium. We then used a SAS macro to review the information reported by study participants to identify jobs associated with each exposure scenario; this was done using previously coded standardized occupation and industry classification codes, and a priori lists of associated key words and phrases related to possibly exposed tasks, tools, and chemicals. Exposure variables representing the occupation, industry, and task/tool/chemicals exposure scenarios were added to the work history records of the study respondents. Our identification of possibly TCE-exposed scenarios in the OH responses was compared to an expert’s independently assigned probability ratings to evaluate whether we missed identifying possibly exposed jobs. Results: Our process added exposure variables for 52 occupation groups, 43 industry groups, and 46 task/tool/chemical scenarios to the data set of OH responses. Across all four agents, we identified possibly exposed task/tool/chemical exposure scenarios in 44–51% of the jobs in possibly exposed occupations. Possibly exposed task/tool/chemical exposure scenarios were found in a nontrivial 9–14% of the jobs not in possibly exposed occupations, suggesting that our process identified important information that would not be captured using occupation alone. Our extraction process was sensitive: for jobs where our extraction of OH responses identified no exposure scenarios and for which the sole source of information was the OH responses, only 0.1% were assessed as possibly exposed to TCE by the expert. Conclusions: Our systematic extraction of OH information found useful information in the task/chemicals/tools responses that was relatively easy to extract and that was not available from the occupational or industry information. The extracted variables can be used as inputs in the development of decision rules, especially for jobs where no additional information, such as job- and industry-specific questionnaires, is available.

    Purpose: Several treatment options are available for patients with prostate cancer. Applicable and valid self-assessment instruments for assessing health-related quality of life (HRQOL) are of paramount importance. The aim of this study was to explore the validity and responsiveness of the intestinal part of the prostate cancer-specific questionnaire QUFW94. Methods and Materials: The content of the intestinal part of QUFW94 was examined by evaluation of experienced clinicians and reviewing the literature. The psychometric properties and responsiveness were assessed by analyzing HRQOL data from the randomized study Scandinavian Prostate Cancer Group 7 (SPCG)/Swedish Association for Urological Oncology 3 (SFUO). Subscales were constructed by means of exploratory factor analyses. Internal consistency was assessed by Cronbach's alpha. Responsiveness was investigated by comparing baseline scores with the 4-year posttreatment follow-up. Results: The content validity was found acceptable, but some amendments were proposed. The factor analyses revealed two symptom scales. The first scale comprised five items regarding general stool problems, frequency, incontinence, need to plan toilet visits, and daily activity. Cronbach's alpha at 0.83 indicated acceptable homogeneity. The second scale was less consistent with a Cronbach's alpha at 0.55. The overall responsiveness was found to be very satisfactory. Conclusion: Two scales were identified in the bowel dimension of the QUFW94; the first one had good internal consistency. The responsiveness was excellent, and some modifications are suggested to strengthen the content validity.

    The CODE questionnaire (COPD detection questionnaire), a simple, binary response scale (yes/no), screening questionnaire, was developed for the identification of patients with chronic obstructive pulmonary disease (COPD). We conducted a survey of 468 subjects with a smoking history in 10 public hospitals in Argentina. Patients with a previous diagnosis of COPD, asthma and other respiratory illness were excluded. Items that measured conceptual domains in terms of characteristics of symptoms, smoking history and demographics data were considered. 96 (20.5%) subjects had a diagnosis of COPD according to the 2010 Global Initiative for Chronic Obstructive Lung Disease strategy document. The variables selected for the final questionnaire were based on univariate and multivariate analyses and clinical criteria. Finally, we selected the presence or absence of six variables (age ?50?years, smoking history ?30?pack-years, male sex, chronic cough, chronic phlegm and dyspnoea). Of patients without any of these six variables (0 points), none had COPD. The ability of the CODE questionnaire to discriminate between subjects with and without COPD was good (the area under the receiver operating characteristic curve was 0.75). Higher scores were associated with a greater probability of COPD. The CODE questionnaire is a brief, accurate questionnaire that can identify smoking individuals likely to have COPD. PMID:26028643

    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.

    Carbon monoxide (CO) poisoning results in not only severe psychoneurological disorders, but can also cause secondary delayed psychoneurological disorders. Therefore, timely and appropriate treatment in the acute stage is crucial to prevent such direct neurological damage and secondary disorders. However, various conflicting results have been reported in studies of CO poisoning treatment, and the efficacy of hyperbaric oxygen therapy (HBO2T) for CO poisoning has not been established. This retrospective multi-institutional study was performed by the questionnaire in 1667 cases of acute CO poisoning in Japan. The effectiveness of HBO2T for CO poisoning was evaluated based on prognoses in cases and various classes of hospital based on the grade of their positive stance regarding HBO2T. The results showed that the prognosis in the group treated with HBOT was significantly better than that in the group treated with normobaric oxygen therapy (NBO2T) (P < 0.01), thus confirming the effectiveness of HBO2T for CO poisoning. Furthermore, while hospitals were separated into three groups according to their indication criteria for HBO2T, the ineffective ratio of NBO2T was dependent on the indication criteria, even though the effective ratio of HBO2T was the same in all three groups. In conclusion, a retrospective multi-institutional study showed that HBO2T is an effective form of therapy for CO poisoning. PMID:22530447

    Background Spirituality has become a subject of interest in health care as it is was recognized to have the potential to prevent, heal or cope with illness. There is less doubt that values and goals are important contributors to life satisfaction, physical and psychological health, and that goals are what gives meaning and purpose to people's lives. However, there is as yet but limited understanding of how patients themselves view the impact of spirituality on their health and well-being, and whether they are convinced that their illness may have "meaning" to them. To raise these questions and to more precisely survey the basic attitudes of patients with severe diseases towards spirituality/religiosity (SpR) and their adjustment to their illness, we developed the SpREUK questionnaire. Methods In order to re-validate our previously described SpREUK instrument, reliability and factor analysis of the new inventory (Version 1.1) were performed according to the standard procedures. The test sample contained 257 German subjects (53.3 ± 13.4 years) with cancer (51%), multiple sclerosis (24%), other chronic diseases (16%) and patients with acute diseases (7%). Results As some items of the SpREUK construct require a positive attitude towards SpR, these items (item pool 2) were separated from the others (item pool 1). The reliability of the 15-item the construct derived from the item pool 1 respectively the 14-item construct which refers to the item pool 2 both had a good quality (Cronbach's alpha = 0.9065 resp. 0.9525). Factor analysis of item pool 1 resulted in a 3-factor solution (i.e. the 6-item sub-scale 1: "Search for meaningful support"; the 6-item sub-scale 2: "Positive interpretation of disease"; and the 3-item sub-scale 3: "Trust in external guidance") which explains 53.8% of variance. Factor analysis of item pool 2 pointed to a 2-factor solution (i.e. the 10-item sub-scale 4: "Support in relations with the External life through SpR" and the 4-item sub-scale 5: "Support of the Internality through SpR") which explains 58.8% of variance. Generally, women had significantly higher SpREUK scores than male patients. Univariate variance analyses revealed significant associations between the sub-scales and SpR attitude and the educational level. Conclusions The current re-evaluation of the SpREUK 1.1 questionnaire indicates that it is a reliable, valid measure of distinct topics of SpR that may be especially useful of assessing the role of SpR in health related research. The instrument appears to be a good choice for assessing a patients interest in spiritual concerns which is not biased for or against a particular religious commitment. Moreover it addresses the topic of "positive reinterpretation of disease" which seems to be of outstanding importance for patients with life-changing diseases. PMID:15705195

    Liquid redox sulfur recovery processes represent an important category of methods currently in use for removing H2S and recovering elemental sulfur from gaseous streams. The Gas Research Institute has been funding research on the complex chemistry of these processes in order to improve their performance and reliability and to evaluate the environmental effects of discharge streams. Since little information is publicly available about the environmental, health, and safety (EH S) practices in operating plants, a questionnaire was developed to gather such information. The questionnaire addressed many of the data gaps in the literature and included five sections; general information, gaseous wastes and odors, liquid waste handling, sulfur and solid waste handling, and chemical handling/housekeeping/maintenance. The EH S questionnaire was distributed to every liquid redox plant that could be identified from literature references and lists supplied by process vendors and from contacts made at GRI-sponsored liquid redox conferences. A total of 59 questionnaires were mailed to plants, and 20 completed questionnaires were returned. Based on the survey responses, the following areas have been recommended for further research: solution blowdown and disposal, sulfur purification, health and safety practices, and regulatory issues.

    International surveys of occupational injuries among seafarers have so far been missing. It was the aim to test the method of self-report of injuries and length of time at risk during the latest duty period and second to study the injury incidence rate among seafarers by use of the method. A pilot study was conducted (n = 1068) in Finland, Denmark, the Philippines, Croatia and Spain using self-completed questionnaires with questions about the person, the ship, the duration of latest duty period and injuries. The duration of the self-reporting duty period was in the Danish part compared with information from the crew register of the Maritime Authority. For seafarers from merchant ships in the Danish sub-study there was acceptable correspondence between the information from the seafarers and the Maritime Authority, but not when referring to ferries and non-specified types of ship. Unadjusted and adjusted injury incidence rates-ratios (IRRs) based on number of injuries per number of work hours were calculated. Adjusted IRRs for ordinary seamen/officers: IRR = 2.43 (95% CI: 1.25-4.72); for age < 35/35+ years: IRR = 1.97 (1.02-3.81); length of tour: 117 days or longer compared with < 117 days: IRR = 0.46 (95% CI: 0.22-0.95); 57-70 working hours per week compared with < 57 h: IRR = 1.26 (0.48-3.29), 71+h compared with < 57 h: IRR = 2.12 (0.84-5.36). Non-significant IRRs >1.00 were found for ships under 10,000 GT compared with larger ships and for own flagged ships compared with ships under flag of convenience. In conclusion, more than 70 h of work per week was related to a higher rate of injuries for seafarers on merchant ships, but the result was not statistically significant. Self-report of the duration of the latest tour of duty is useful for seafarers from merchant ships with short-term employments, but not for ferries and other, non-specified types of ship with other or permanent employment.

    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

    There is currently no uniform definition of cutaneous lupus erythematosus (CLE) upon which to base a study population for observational and interventional trials. A preliminary questionnaire was derived from and sent to a panel of CLE experts which demonstrated consensus agreement that (1) there is a need for new definitions for CLE (2) CLE is distinct from systemic lupus erythematosus and that a CLE grouping scheme should remain apart from current systemic lupus erythematosus schema (3) current CLE grouping schemes are inadequate around communication, prognostic information and to meet the needs of researchers, clinicians, patients and payers.

    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

    A questionnaire was sent to the 590 members of the European Society of Intensive Care Medicine to define both the current practices and the opinions of these specialists on various ethical issues. The answers from 242 (41%) European members were collected and analysed. The first part of the questionnaire was designed to define the criteria for admission to Intensive Care throughout Europe. Admissions to the ICU were generally or commonly limited by the number of available beds according to 57% of the respondents and sometimes or almost never according to 41% (100/242). Bed availability in the ICU was especially limited in Spain, Portugal, Italy and the United Kingdom. Despite limited bed availability, two thirds of the respondents did admit patients who were thought to have little or no hope of survival other than for a few weeks. When asked about what ought to be done in these circumstances, the number of respondents who supported the admission of such terminal patients to ICU was halved. These data illustrate the heterogeneity of admission practices in Europe and stress the need for all ICUs to define a policy for admission. The second part was designed to assess the information given to patients in the ICU. Only 24 (10%) of the respondents stated that they always delivered complete information to their patients and only 31 (13%) thought they should do so. When an iatrogenic incident occurred, only 39 (16%) claimed to relate exactly what had happened, to the patient or their relatives but 121 (50%) thought they should. Informed consent was usually required for surgery or gastroscopy and the administration of a new medication. PMID:2358559

    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.

    2014-01-01

    Four studies created malingering and response bias scales for a new test battery, the Attachment and Clinical Issues Questionnaire (ACIQ). In the first calibration study, a new approach to identifying fake good and fake bad respondents was outlined. In Study 2, this scale was cross validated in a within-subjects design that also found only weak correlations between the scales of the ACIQ and measures of social desirability. The third study developed a method violator scale (one who responds randomly to the content of the scales due to carelessness, low IQ, etc.). It was tested by Monte Carlo and empirical studies. The fourth study combined the two cross validation studies to offer clear cutoffs for the practitioner. These studies successfully led to the creation of malingering and response bias scales for the ACIQ and also introduced new methods that could be adapted to other instruments. PMID:24846785

    1996-06-01

    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

  8. The ChQoL questionnaire: an Italian translation with preliminary psychometric results for female oncological patients

    PubMed Central

    2010-01-01

    Background in Occidental languages, no widely accepted questionnaire is available which deals with health related quality of life from the specific point of view of Traditional Chinese Medicine (TCM). Some psychometric tools of this kind are available in Chinese. One of them is the Chinese Quality of Life questionnaire (ChQoL). It comprises 50 items, subdivided in 3 Domains and 13 Facets. The ChQoL was built from scratch on the basis of TCM theory. It is therefore specifically valuable for the TCM practitioner. This paper describes our translation into Italian of the ChQoL, its first application to Occidental oncological patients, and some of its psychometric properties. Methods a translation scheme, originally inspired by the TRAPD procedure, is developed. This scheme focuses on comprehensibility and clinical usefulness more than on linguistic issues alone. The translated questionnaire is tested on a sample of 203 consecutive female patients with breast cancer. Shapiro-Wilk normality tests, Fligner-Killeen median tests, exploratory Two-step Cluster Analysis, and Tukey's test for non-additivity are applied to study the outcomes. Results an Italian translation is proposed. It retains the TCM characteristics of the original ChQoL, it is intelligible to Occidental patients who have no previous knowledge of TCM, and it is useful for daily clinical practice. The score distribution is not Normal, and there are floor and ceiling effects. A Visual Analogue Scale is identified as a suitable choice. A 3-point Likert scale can also efficiently describe the data pattern. The original scales show non-additivity, but an Anscombe-Tukey transformation with ? = 1.5 recovers additivity at the Domain level. Additivity is enhanced if different ? are adopted for different Facets, except in one case. Conclusions the translated questionnaire can be adopted both as a filing system based on TCM and as a source of outcomes for clinical trials. A Visual Analogue Scale is recommended, but a simpler 3-point Likert scale also suitably fits data. When estimating missing data, and when grouping items within Domain in order to build a summary Domain index, an Anscombe-Tukey transformation should be applied to the raw scores. PMID:20868514

    Background The most commonly used survey methods are self-administered questionnaires, telephone interviews, and a mixture of both. But until now evidence out of randomised controlled trials as to whether patient responses differ depending on the survey mode is lacking. Therefore this study assessed whether patient responses to surveys depend on the mode of survey administration. The comparison was between mailed, self-administered questionnaires and telephone interviews. Methods A four-armed, randomised controlled two-period change-over design. Each patient responded to the same survey twice, once in written form and once by telephone interview, separated by at least a fortnight. The study was conducted in 2003/2004 in Germany. 1087 patients taking part in the German Acupuncture Trials (GERAC cohort study), who agreed to participate in a survey after completing acupuncture treatment from an acupuncture-certified family physician for headache, were randomised. Of these, 823 (664 women) from the ages of 18 to 83 (mean 51.7) completed both parts of the study. The main outcome measure was the comparison of the scores on the 12-Item Short-Form Health Survey (SF-12) and the Graded Chronic Pain Scale (GCPS) questionnaire for the two survey modes. Results Computer-aided telephone interviews (CATI) resulted in significantly fewer missing data (0.5%) than did mailed questionnaires (2.8%; p < 0.001). The analysis of equivalence revealed a difference between the survey modes only for the SF-12 mental scales. On average, reported mental status score was 3.5 score points (2.9 to 4.0) lower on the self-administered questionnaire compared to the telephone interview. The order of administration affected results. Patients who responded to the telephone interview first reported better mental health in the subsequent paper questionnaire (mean difference 2.8 score points) compared to those who responded to the paper questionnaire first (mean difference 4.1 score points). Conclusion Despite the comparatively high cost of telephone interviews, they offer clear advantages over mailed self-administered questionnaires as regards completeness of data. Only items concerning mental status were dependent on the survey mode and sequence of administration. Items on physical status were not affected. Normative data for standardized telephone questionnaires could contribute to a better comparability with the results of the corresponding standardized paper questionnaires. PMID:18034900

    Participants in the College of American Pathologists' Mycobacteriology E proficiency testing survey in 1993 were asked to complete a questionnaire addressing mycobacterial test methods, test volume, and frequency of detection of drug-resistant Mycobacterium tuberculosis (MTB). A similar questionnaire had been distributed in 1992. The population responding to the 1993 questionnaire changed, because of a shift of small hospitals to the limited Mycobacteriology E1 survey, and the format of some questions was altered, so a direct comparison of 1992 and 1993 responses was not always possible. Among participants who answered the questions in both years, there was a significant increase in the use of the fluorochrome stain (57% in 1992, 61% in 1993), BACTEC TB for culture (34% in 1992, 38% in 1993) and susceptibility testing (51% in 1992, 61% in 1993), and DNA probes for identification (30% in 1992, 51% in 1993). The percentage of participants who processed respiratory specimens at least seven times per week increased from 9% in 1992 to 13% in 1993, and the percentage processing five times per week increased from 68 to 72%. The percentage of respondents who reported an identification of MTB within 21 days of specimen receipts and susceptibility test results within 28 days in 1992 and 1993 increased from 30 to 41% and from 12 to 19%, respectively. In regard to resistant MTB, 177 institutions in 1991 and 291 in 1992 reported resistance to isoniazid, and 114 in 1991 and 187 in 1992 reported resistance to both isoniazid and rifampin. Laboratorians are to be applauded for using the more rapid mycobacterial testing methods; however, given that tuberculosis remains a problem, this trend must continue. PMID:7714200

    Background The proportion of Japanese workers experiencing intense worry or stress during working life is in excess of 60%, and the incidence of psychiatric disorders and suicide due to psychological burden from work duties is increasing. To confirm whether the stress response measured by the Brief Job Stress Questionnaire (BJSQ) can identify risk for depression, a cohort study was conducted to evaluate whether the stress response measured by BJSQ was associated with the onset of depression. Methods A total of 1,810 participants aged 20–70 years in 2005 completed the stress response of the BJSQ and were followed-up until August, 2007 by examining sick pay records. Depression was defined by a description in sick pay records that included “depression” or “depressive symptoms” as a reason for sick leave according to a physician's medical certificate. The participants were divided into quartiles (Ql, Q2, Q3, and Q4) according to the total stress response score of BJSQ at baseline. Furthermore, the participants were divided into a higher score category (Q4) and a lower score category (Q1–Q3). Risk ratios of the stress response of the BJSQ for onset of depression were calculated using a multivariable Cox proportional hazard model. Results Among 1,810 participants, 14 developed depression during a mean of 1.8 years of follow-up. The risk ratio was 2.96 (95% confidence interval [CI], 1.04–8.42, p for trend?=?0.002) when the higher stress response score category of BJSQ was compared with the low stress response score category for sick leave due to depression. After adjusting for gender, age, marital status, and having children, the risk ratios were similar to no adjustment. Conclusions These findings suggest that the stress response measured by the BJSQ can demonstrate risk for the onset of depression. PMID:23424656

  16. Re-evaluating a vision-related quality of life questionnaire with item response theory (IRT) and differential item functioning (DIF) analyses

    PubMed Central

    2011-01-01

    Background For the Low Vision Quality Of Life questionnaire (LVQOL) it is unknown whether the psychometric properties are satisfactory when an item response theory (IRT) perspective is considered. This study evaluates some essential psychometric properties of the LVQOL questionnaire in an IRT model, and investigates differential item functioning (DIF). Methods Cross-sectional data were used from an observational study among visually-impaired patients (n = 296). Calibration was performed for every dimension of the LVQOL in the graded response model. Item goodness-of-fit was assessed with the S-X2-test. DIF was assessed on relevant background variables (i.e. age, gender, visual acuity, eye condition, rehabilitation type and administration type) with likelihood-ratio tests for DIF. The magnitude of DIF was interpreted by assessing the largest difference in expected scores between subgroups. Measurement precision was assessed by presenting test information curves; reliability with the index of subject separation. Results All items of the LVQOL dimensions fitted the model. There was significant DIF on several items. For two items the maximum difference between expected scores exceeded one point, and DIF was found on multiple relevant background variables. Item 1 'Vision in general' from the "Adjustment" dimension and item 24 'Using tools' from the "Reading and fine work" dimension were removed. Test information was highest for the "Reading and fine work" dimension. Indices for subject separation ranged from 0.83 to 0.94. Conclusions The items of the LVQOL showed satisfactory item fit to the graded response model; however, two items were removed because of DIF. The adapted LVQOL with 21 items is DIF-free and therefore seems highly appropriate for use in heterogeneous populations of visually impaired patients. PMID:21888648

    Background Chronic kidney disease is an increasing health problem worldwide and in its final stage (stage V) can only be treated by renal replacement therapy, mostly hemodialysis. Hemodialysis has a major influence on the everyday life of patients and many patients report dissatisfaction with treatment. Little is known about which aspects of treatment are considered important by hemodialysis patients. The objective of this study was to rate the relative importance of different outcomes for hemodialysis patients and to analyze whether the relative importance differed among subgroups of patients. Patients and methods Within the framework of a yearly questionnaire which is distributed among patients receiving hemodialysis by the largest hemodialysis provider in Germany, we assessed the relative importance of 23 outcomes as rated on a discrete visual analog scale. Descriptive statistics were used to rank the outcomes. Subgroup analyses were performed using Mann–Whitney U or Kruskal–Wallis tests. Results Questionnaires of 4,518 hemodialysis patients were included in the analysis. The three most important outcomes were safety of treatment, health-related quality of life, and satisfaction with care. Further important outcomes were hospital stays, accompanying symptoms, hemodialysis duration, and the improvement or preservation of a good emotional state. Age, profession, and education had the strongest influence on relevant differences of preferences for outcomes; no relevant influence of sex or comorbidity was observed. Conclusion Outcomes concerning the delivery or provision of care and aspects influencing quality of life are rated by patients to be at least as important as clinical outcomes. Many of the outcomes judged to be important by the patients are not regularly considered in research, evaluation studies, or quality programs. PMID:26170634

    2015-01-01

    Notwithstanding the wide use of the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF) as a brief assessment of trait emotional intelligence (TEI), the psychometric properties of this measure have not been systematically examined. This article reports on research conducted to evaluate the latent structure underlying TEIQue-SF item data and test the gender invariance of scores as critical initial steps in determining the psychometric robustness of the inventory. In doing so, the article demonstrates an application of exploratory structural equation modeling as an alternative to the more restrictive independent clusters model of confirmatory factor analysis for examining factorially complex personality data. On the basis of 476 responses to the TEIQue-SF, evidence was obtained for the multidimensionality of the inventory reflected in a retained correlated traits solution. Tests of gender invariance revealed equivalence of item factor loadings, intercepts, uniquenesses, correlated uniquenesses, and the factor variance-covariance matrix, but not latent means. Men were found to be moderately higher on self-control and sociability than women, whereas women scored marginally higher on emotionality than men. No significant gender differences were found on mean levels of well-being. The benefits of the multidimensionality of the TEIQue-SF, limitations of the study, and directions for future research are discussed. PMID:25774661

    Objectives : To study variations in Canadian clinical practice patterns for the management of ANCA-associated vasculitis (AAV) and identify points to consider for the development of national recommendations. Material and Methodology : A 30-item needs assessment questionnaire was sent to all members of the Canadian Vasculitis network (CanVasc), Canadian Rheumatology Association (CRA), Canadian Thoracic Society (CTS) and Canadian Society of Nephrology (CSN). Respondent characteristics, practice patterns, concerns and expectations were analyzed. Results : Among 132 physicians who followed at least 1 vasculitis patient and responded to the survey, 39% stated that they felt confident in their management of AAV. Several variations in practice were observed regarding diagnostic procedure, induction and maintenance treatments and use of biologics; some were due to logistic constraints (difficulties in access to some specific tests, drugs or care; lack of health care coverage for the costs). The top 5 topics for which recommendations are expected involve treatment for remission induction, maintenance, refractory disease, and relapse as well as biologics. Conclusion : Practice variations identified in this needs assessment survey will serve to formulate key questions for the development of CanVasc recommendations. PMID:25893028

    Summary Background As a consequence of the German Transfusion Act and the corresponding Hemotherapeutic Guidelines of the German Medical Association, the National Advisory Committee Blood approved a recommendation (votum 29) in 2003 to specify students’ training in transfusion medicine, hemotherapy, and hemostasis. The objective of this study was to assess the current status of teaching in these fields. Methods A questionnaire-based evaluation was performed at the medical schools in Germany (n = 34). Responses were analyzed by descriptive criteria, except for weekly semester hours of teaching. Results Responses were obtained from 30 medical faculties (88%). Among them, 18 had conducted votum 29 (12 ‘completely’, 6 ‘essentially’), while 7 had done so only ‘in part’ and 5 ‘not at all’. 13 of 30 sites (43%) reported that no faculty-related curriculum in transfusion medicine and hemostasis (hemotherapy) exists. At 28 of 30 medical schools (93%), teaching in transfusion medicine, hemotherapy, and hemostasis is integrated into cross-curricular topics of interdisciplinary programs, including lectures. The corresponding semester hours of teaching per week ranged from 0.5 to 12 h/week. Conclusion Votum 29 is incompletely established. Consequently, academic teaching in transfusion medicine, hemotherapy, and hemostasis requires structural and conceptual improvement to fulfill legal specifications and regulatory constraints.

  3. Results from the translation and adaptation of the Iranian Short-Form McGill Pain Questionnaire (I-SF-MPQ): preliminary evidence of its reliability, construct validity and sensitivity in an Iranian pain population

    PubMed Central

    2011-01-01

    Background The Short Form McGill Pain Questionnaire (SF-MPQ) is one of the most widely used instruments to assess pain. The aim of this study was to translate and culturally adapt the questionnaire for Farsi (the official language of Iran) speakers in order to test its reliability and sensitivity. Methods We followed Guillemin's guidelines for cross-cultural adaption of health-related measures, which include forward-backward translations, expert committee meetings, and face validity testing in a pilot group. Subsequently, the questionnaire was administered to a sample of 100 diverse chronic pain patients attending a tertiary pain and rehabilitation clinic. In order to evaluate test-retest reliability, patients completed the questionnaire in the morning and early evening of their first visit. Finally, patients were asked to complete the questionnaire for the third time after completing a standardized treatment protocol three weeks later. Intraclass correlation coefficient (ICC) was used to evaluate reliability. We used principle component analysis to assess construct validity. Results Ninety-two subjects completed the questionnaire both in the morning and in the evening of the first visit (test-retest reliability), and after three weeks (sensitivity to change). Eight patients who did not finish treatment protocol were excluded from the study. Internal consistency was found by Cronbach's alpha to be 0.951, 0.832 and 0.840 for sensory, affective and total scores respectively. ICC resulted in 0.906 for sensory, 0.712 for affective and 0.912 for total pain score. Item to subscale score correlations supported the convergent validity of each item to its hypothesized subscale. Correlations were observed to range from r2 = 0.202 to r2 = 0.739. Sensitivity or responsiveness was evaluated by pair t-test, which exhibited a significant difference between pre- and post-treatment scores (p < 0.001). Conclusion The results of this study indicate that the Iranian version of the SF-MPQ is a reliable questionnaire and responsive to changes in the subscale and total pain scores in Persian chronic pain patients over time.

    The Strengths and Difficulties Questionnaire (SDQ) is a short behavioural screening questionnaire which can be completed in about five minutes by parents and teachers of 4- to 16-year-olds or as self-report by 11- to 16-year-olds. The English original has already been fully evaluated and is widely used in research and clinical practice. The instrument was translated into German in 1997, and several evaluative studies have since been completed. The present paper gives an overview of this novel instrument and summarizes the normative and validation studies to date. A normative study on a field sample of 930 children demonstrated that the distributions of raw scores in the German parent SDQ closely resemble those found in the English version, while a factor analysis of the German data yielded a pattern of loadings which convincingly replicated the original scale structure. Initial validation studies showed that the parent-, teacher-, and self-completed SDQ-Deu correlates well with the considerably longer German versions of the Child Behavior Checklist (CBCL) and respective teacher and self-report derivatives (TRF, YSR). Both parent-rated instruments are equally able to distinguish between a community and a clinic sample, and between subgroups with and without specified categories of disorders within a clinic sample. After discussing possible uses of the SDQ-Deu as well as similarities and differences to other scales, we conclude that the German SDQ is just as useful and valid an instrument for many clinical and research purposes as the English original.

    In December 1996, a questionnaire about farm management and parasite control measures in calves was sent to 956 randomly chosen dairy cattle farmers in The Netherlands. Another 150 farmers in the vicinity of Deventer who had vaccinated their calves in 1995 against lungworm were approached with the same questions. Our object was to investigate the consequences on worm control of the withdrawal of the lungworm vaccine from the market for reasons of possible BSE contamination of the vaccine. OF the returned questionnaires, 411 (43%) of the 'at random' group and 89 (59.3%) of the 'Deventer' group were valid. The most important data with regard to the farms of the 'at random' group (41) were: mean area 31.6 ha, mean number of calves 23, heifers 23 and milking cows 53. Sheep (mean 37) were present on 18.3% of the farms. With regard to management: 74.5% of the farmers turned the calves in their first year onto pasture, 25.5% kept them indoors. The average time on pasture was ca. 5 months. Rational grazing was practise on 81.4% of the farms, on 18.6% calves were set stocked. The first pasture of the calves was mown before turn-out on 72.9% of the farms. On 48.2% of these farms, calves were always moved to mown pastures. With regard to treatments: 33.8% of the farmers vaccinated their calves against lungworm in the years 1993, 1994 and 1995. Despite the withdrawal of the vaccine from the market in 1996, 7.2% of the farmers vaccinated their calves as recommended, with two doses, and 13.1% with a single dose. At turn-out, 41.5% of the farmers gave the calves a preventive anthelmintic treatment. Of these treatments, 66.9% were sustained of pulse release long acting device. During the grazing season, 36.6% of the farmers treated their calves. After housing 50.3% of the farmers gave a treatment. Signs of lungworm infection were noticed on 18.6% of the farms. Of the 'Deventer' group (89 farmers), 96.6% turned the calves out, Of these farmers, 86.0% had used the lungworm vaccine in 1995. In 1996, 52.7% of the farmers had vaccinated the calves:36.5% with a single dose and 16.2% with the double dose. Of the 35 farmers who did not vaccinate in 1996, 62.9% gave a preventive treatment at turn-out. Clinical signs of lungworm infection were not observed on the 12 farms which vaccinated the calves twice. On 11% of the farms which vaccinated once and on 14% of the farms which did not vaccinate, signs of lungworm infection were observed. It is concluded that more than 80% of Dutch dairy cattle farmers take appropriate measures to control gastrointestinal nematode and lungworm infections in calves in their first grazing season by grazing on aftermath, rotational grazing on mown pastures combined or not with preventive anthelmintic treatments. However, combinations of aftermath grazing and preventive treatment occurred on 30% of the farms. This may be overprotective and may prevent sufficient build up of immunity, causing worm problems at a later age. The withdrawal of the lungworm vaccine from the market did not cause a rise in lungworm problems. Some farmers did vaccinate, despite the withdrawal. The majority used other preventive treatment measures, mainly the application of long acting boli. PMID:9703617

  14. Clinical Trial Adaptation by Matching Evidence in Complementary Patient Sub-groups of Auxiliary Blinding Questionnaire Responses

    Clinical trial adaptation refers to any adjustment of the trial protocol after the onset of the trial. Such adjustment may take on various forms, including the change in the dose of administered medicines, the frequency of administering an intervention, the number of trial participants, or the duration of the trial, to name just some possibilities. The main goal is to make the process of introducing new medical interventions to patients more efficient, either by reducing the cost or the time associated with evaluating their safety and efficacy. The principal challenge, which is an outstanding research problem, is to be found in the question of how adaptation should be performed so as to minimize the chance of distorting the outcome of the trial. In this paper we propose a novel method for achieving this. Unlike most of the previously published work, our approach focuses on trial adaptation by sample size adjustment i.e. by reducing the number of trial participants in a statistically informed manner. We adopt a stratification framework recently proposed for the analysis of trial outcomes in the presence of imperfect blinding and based on the administration of a generic auxiliary questionnaire that allows the participants to express their belief concerning the assigned intervention (treatment or control). We show that this data, together with the primary measured variables, can be used to make the probabilistically optimal choice of the particular sub-group a participant should be removed from if trial size reduction is desired. Extensive experiments on a series of simulated trials are used to illustrate the effectiveness of our method. PMID:26161797

    Evidence of higher coronary heart disease mortality rates among blacks than among whites raises questions concerning differences in health care-seeking for heart disease between blacks and whites. As part of a larger project evaluating health care-seeking behavior for coronary heart disease, we interviewed hospitalized patients who had diagnoses of coronary artery disease, ischemic heart disease, chest pain, or myocardial infarction, or who were admitted to rule out myocardial infarction. The sample included 1140 white men, 347 black men, 574 white women, and 355 black women. The interview included demographic information, usual care, access to usual care, and chest pain items. Demographic and medical care access differences emerged between African-American and white participants. We also compared the prevalence of Rose Questionnaire angina between blacks and whites. Among patients who scored positively for Rose angina, black men reported more recent onset of their angina and fewer episodes during the past 6 months compared to all other groups, and they sought medical care less often compared with white men. Multiple logistic regression analyses suggest that African-American respondents were less likely to score positively for Rose angina and were less likely to seek treatment for their symptoms among those who had angina, when controlled for demographic, risk factor, and access to care variables. Blacks and whites in our sample also differed in factors associated with scoring positive for angina and seeking medical care for their symptoms, among those who reported angina. We interpret these findings as suggesting that promoting routine usual care among whites may be an important approach for increasing care-seeking for coronary heart disease symptoms. For blacks, improved coronary heart disease case identification and/or educational approaches to promote greater awareness of symptoms and of the need for seeking treatment for symptoms may be important to increase the likelihood that they will seek medical care for their symptoms.

    This study examined the construct validity and clinical utility of S. Nolen-Hoeksema's (1991) Response Styles Questionnaire (RSQ) Rumination scale. Eighty-eight participants with recent-onset major depressive episodes were assessed and followed for 6 months, using semistructured interviews and self-report inventories. The RSQ Rumination scale exhibited poor 6-month stability and appeared to be closely linked to participants' clinical status-mood state. The scale was significantly correlated with conceptually related constructs such as emotion-focused coping, negative affectivity-temperament, and self-criticism. However, baseline negative temperament and self-criticism predicted key aspects of the 6-month course and outcome of major depressive episodes, whereas baseline rumination did not. Finally, rumination appeared to be closely associated with the severity of the depressive episode, rather than defining a distinct clinical subtype. PMID:11556274

    Malnutrition as the cause of developing atherosclerosis is undoubtedly of major importance. For that reason, proper nutrition and eating habits among the population is of specific significance in preventive medicine. In order to establish a more pronounced food consciousness among the population of Styria, a questionnaire was issued to 1.354 persons attending the Graz Autumn Fair in 1991. The results showed above all that approximately 40% of the subjects investigated presented a disease due to malnutrition and metabolic disorder, mainly hyperlipidemia. The choice of various foods varied according to male and female tastes; roasted pork was more often a men's favourite dish (p < 0.001) while women had a prediction for vegetarian food (p < 0.001). There was, however, no difference in the choice of eating habits in persons with or without metabolic disorders. Thus, women in general do pursue a healthier consciousness was not so pronounced in man. Yet, it could not be established by means of the questionnaire that subjects with metabolic disorders showed different eating habits with respect to their disease. PMID:8212721

    In addition to the subject objective, the relationship of specified personality variables (i.e., trait anxiety, locus of control, response tendency towards threat, and denial) to behavioral and psychological responses to the threat of nuclear war were assessed. The quantitative questionnaire, titled the Nuclear Reaction Scale, was composed of items selected from issues discussed in the psychological literature on the threat of nuclear war. These issues included: psychic numbing, cognitive reality, perceptions of likelihood and survival, nuclear illusions, and attention to the threat of nuclear war. A standardization sample of 360 college students was administered the Nuclear Reaction Scale, Trait Anxiety Scale, Internal-External Locus of Control Scale, Facilitation-Inhibition Scale, and Haan Denial Scale. Three additional subsamples, identified as Military, Nuclear Freeze, and Church, were given the Nuclear Reaction Scale to assess the validity of the scale. A factor analysis of the Nuclear Reaction Scale indicated a nine-factor solution that described issues such as concern perceptions, likelihood, survivability, and control over the threat of nuclear war. A number of strong relationships existed between computed factors on the Nuclear Reaction Scale. Demographic comparisons found significant differences related to sex and political affiliation.

    Hairdressers are under a high occupational risk of developing various health disorders, particularly regarding the skin. The "SafeHair" project was implemented from 2010 to 2012, with the aim to develop health and safety standards for the prevention of occupational skin diseases in hairdressing. Croatian hairdressers participated in the project. The aim of this work was to establish the actual status of skin protection in Croatian hairdressers. Data were collected by the EvaHair questionnaire developed within the "SafeHair" project. A total of 213 questionnaires were analysed. The sample comprised 133 (64%) salon owners, 46 (22%) employees, and 31 (14%) trainees. Thirty-six (17%) subjects confirmed the presence of skin disorders in their salons in the last 3 years, and almost all of the subjects (98%) considered the prevention of occupational skin diseases important. We found a high proportion (from 40% to 50%) of non-answered questions about risk assessment. Protective gloves were mostly used when exposed to chemicals (88%), but rarely for hair washing (13%). They were available to the majority of subjects (95%), but 32% of subjects had trouble wearing them. Hairdressers with over 30 years of working experience used gloves for washing and cutting hair more frequently than those with less than 30 years of experience (p<0.05). Education on skin protection was more often provided (39%) than education on the protection of the respiratory (15%) and musculosceletal (18%) systems. A high proportion of subjects needed assistance with interpreting laws, regulations, and information about products (57%), as well as in the implementation of risk assessment methods (49%). The results indicate a need for further education on the health risks and the implementation of protective measures. This should be carried out during vocational education and later in the form of permanent education. PMID:23819939

    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

    OBJECTIVES: To determine rates of other atopic manifestations in people with peanut allergy and the prevalence of such allergy in their families. DESIGN: A survey of people with self reported peanut allergy and people referred by their general practitioner for suspected peanut allergy; survey and skin testing of 50 children with reported peanut allergy and their available first degree relatives. SUBJECTS: 622 adults and children with reported, suspected, or known peanut allergy. MAIN OUTCOME MEASURES: Prevalence of peanut allergy and other allergies in the families of people with peanut allergy. RESULTS: 622 valid completed questionnaires were returned out of the 833 questionnaires dispatched (74.7%). All forms of atopy were both more common in successive generations (P < 0.0001) and more common in maternal than paternal relatives (P < 0.0001). Peanut allergy was reported by 0.1% (3/2409) of grandparents, 0.6% (7/1213) of aunts and uncles, 1.6% (19/1218) of parents, and 6.9% (42/610) of siblings. Consumption of peanuts while pregnant or breast feeding was more common among mothers of probands aged < or = 5 years than mothers of probands aged > 5 years (P < 0.001). Age of onset correlated inversely with year of birth (r = -0.6, P < 0.001). Skin prick testing of 50 children with reported peanut allergy and their families: 7 probands (14%) had a negative result for peanut. Peanut allergy was refuted by food challenge in all those tested (5/7). No parent and 13% (5/39) of siblings had a positive result on skin prick testing for peanut. Two of these siblings had negative challenge with peanuts. The prevalence of peanut allergy in siblings is therefore 3/39 (7%). CONCLUSIONS: Peanut allergy is more common in siblings of people with peanut allergy than in the parents or the general population. Its apparently increasing prevalence may reflect a general increase of atopy, which is inherited more commonly from the mother. Peanut allergy is presenting earlier in life, possibly reflecting increased consumption of peanut by pregnant and nursing mothers. PMID:8789975

    Previous research suggests that there is a great deal of variability among older adults' response to memory training. Using latent class analysis, we examined data from the memory training arm of the Advanced Cognitive Training for Independent and Vital Elderly Trial (ACTIVE), a large randomized controlled cognitive training trial, to determine if there were distinct patterns of responsiveness to training. Additionally, we examined whether baseline demographic and cognitive factors were predictive of these response patterns. The results indicate that among memory-trained participants, there are 3 distinct response patterns, suggesting that participants gravitate toward specific mnemonic techniques. Furthermore, baseline memory and speed of processing abilities, age, and education are predictive of these distinct response patterns. Taken together, the findings suggest that we can characterize and predict older adults' response to memory training. PMID:19196693

    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.

    Background Consensus on how to adequately measure patient satisfaction with health care is limited, and has led to the development of many questionnaires with various methodological problems. The objective of this study was to develop a liver disease- and care-specific patient satisfaction instrument on the basis of previously tested methodology in patient satisfaction measurement, the so called QUOTE- series: Quality Of health care services Through the patients' Eyes. QUOTE methodology aims to standardise the measurement of satisfaction as the discrepancy between patients' needs, and the extent to which these needs are being met. Methods As part of the QUOTE methodology routine, 11 Patients with chronic liver disease from the Erasmus MC (Rotterdam, the Netherlands) participated in focus-group meetings on patient satisfaction with the provided service at the outpatient hepatology clinic. Twenty-eight other patients were invited to rank the items generated during the focus-group meetings according to importance. With this information, the QUOTE-Liver was constructed. Face validity, construct validity, content validity, and reliability of the newly developed questionnaire were assessed in a test sample of 152 patients with chronic liver disease. Results Two liver-disease specific, and the 18 items ranked as most important were included in the QUOTE-Liver. Face validity and content validity were acceptable: neither patients (n = 152) nor psychologists (n = 3) or a hepatologist suggested any extra items to be included. Construct validity was good: the overall score correlated significantly with the Visual Analogue Scale (VAS) measuring overall satisfaction (r = 0.69, p < 0.01). The reliability of the QUOTE-Liver was excellent (? = 0.90). Conclusion The QUOTE-Liver is an easy to complete instrument based on standardized state-of-the-art satisfaction measurement methodology. Preliminary evidence for its validity and reliability was demonstrated. The QUOTE-liver covers those aspects of satisfaction that CLD patients consider to be important when visiting the outpatient department of hepatology. Even though further substantiating of the favourable psychometric findings is desirable, it seems to be a useful instrument that can be used to identify those aspects of care that need improvement in order to optimise the provision of health care for patients with chronic liver disease.

    BACKGROUND: A poor communication with immigrants can lead to inappropriate use of healthcare services, greater risk of misdiagnosis, and lower compliance with treatment. As precise information about communication between emergency physicians (EPs) and immigrants is lacking, we analyzed difficulties in communicating with immigrants in the emergency department (ED) and their possible associations with demographic data, geographical origin and clinical characteristics. METHODS: In an ED with approximately 85 000 visits per year, a multiple-choice questionnaire was given to the EPs 4 months after discharge of each immigrant in 2011. RESULTS: Linguistic comprehension was optimal or partial in the majority of patients. Significant barriers were noted in nearly one fourth of patients, for only half of them compatriots who were able to translate. Linguistic barriers were mainly found in older and sicker patients; they were also frequently seen in patients coming from western Africa and southern Europe. Non-linguistic barriers were perceived by EPs in a minority of patients, more frequently in the elderly and frequent attenders. Factors independently associated with a poor final comprehension led to linguistic barriers, non-linguistic obstacles, the absence of intermediaries, and the presence of patient’s fear and hostility. The latter probably is a consequence, not the cause, of a poor comprehension. CONCLUSION: Linguistic and non-linguistic barriers, although quite infrequent, are the main factors that compromise communication with immigrants in the ED, with negative effects especially on elderly and more seriously ill patients as well as on physician satisfaction and appropriateness in using services.

    Background and Purpose A population-based door-to-door study of cross-sectional methods for assessing the prevalence and factors related to a high risk of obstructive sleep apnea (OSA) was conducted using the Korean version of the Berlin Questionnaire (K-BQ). Methods Pooled data collected from Community Health Surveys by the Korea Center for Disease Control and Prevention were analyzed. Of 8,140 respondents from the population, 7,955 were finally included in this study. Results Of the 7,955 included subjects, 15.7% of the men and 9.8% of the women were at high risk of OSA. Significant differences were found in the following factors between the subjects with a high risk of OSA: gender, age, marital status, educational level, occupation, and presence of smoking, harmful alcohol use, and chronic diseases. Male sex, harmful alcohol use, and the presence of chronic diseases were identified as factors independently associated with a high risk of OSA. Conclusions This is the first study to confirm the usefulness of the K-BQ to study the prevalence of OSA in the Korean general population. The findings demonstrate that harmful alcohol use and chronic diseases are very common characteristics among those with a high risk of OSA. PMID:24465262

    2014-01-01

    Background The objective of this study was to develop a questionnaire for caregivers to assess the eating behavior of Chinese preschoolers. Methods To assess children’s eating behaviors, 152 items were derived from a broad review of the literature related to epidemiology surveys and the assessment of children’s eating behaviors. All of these items were reviewed by 50 caregivers of preschoolers and 10 experienced pediatricians. Seventy-seven items were selected for use in a primary questionnaire. After conducting an exploratory factor analysis and a variability analysis on the data from 313 preschoolers used to evaluate this primary questionnaire, we deleted 39 of these 77 items. A Chinese Preschoolers’ Eating Behavior Questionnaire (CPEBQ) was finally established from the remaining 38 items. The structure of this questionnaire was explored by factor analysis, and its reliability, validity and discriminative ability were evaluated with data collected from caregivers of 603 preschoolers. Results The CPEBQ consisted of 7 dimensions and 38 items. The 7 dimensions were food fussiness, food responsiveness, eating habit, satiety responsiveness, exogenous eating, emotional eating and initiative eating. The Cronbach’s ? coefficient for the questionnaire was 0.92, and the test-retest reliability was 0.72. There were significant differences between the scores of normal-weight, overweight and obese preschoolers when it was referred to food fussiness, food responsiveness, eating habits, satiety responsiveness and emotional eating (p<0.05). Differences in caregiver’s education levels also had significant effects on scores for food fussiness, eating habits and exogenous eating (p<0.05). Conclusions The CPEBQ satisfies the conditions of reliability and validity, in accordance with psychometric demands. The questionnaire can be employed to evaluate the characteristics of Chinese preschoolers’ eating behaviors; therefore, it can be used in child health care practice and research. PMID:24520359

    The dynamic response of Howden's 330-kW horizontal-axis wind turbine (HAWT) and the Northern Power Systems 100-kW ''North Wind 100'' HAWT has been measured. The Howden machine incorporates a 26-m-diameter, upwind, three-bladed, wood/epoxy rotor that operates at 42 rpm and is a rigid-hub design. The North Wind 100 rotor has a diameter of 17.8 m, is upwind, two-bladed, and constructed of fiberglass, and has a teetered hub. The Northern Power turbine's blades are fully pitchable, while the Howden machine uses pitchable blade tips. This paper will present the results from each of these test programs in an effort to compare the dynamic response of each turbine. The analysis will focus on rotor bending loads in terms of both time domain and frequency response. The FLAP code will be used to explore sensitivity to teeter stiffness and natural frequency placement to provide a better understanding of the differences in behavior caused by configuration alone. The results are presented in the form of normalized azimuth-averaged plots of the deterministic loads, and spectral density plots of the stochastic responses. This presentation of the results will contrast major response differences due to design configurations. 6 refs., 19 figs., 3 tabs.

    This study compares the results of the Korea National Health and Nutrition Examination Survey (Self-Reported; KNHANEs [SR]) survey with urine-cotinine concentration (UCC) and the official index issued by the Korea Youth Risk Behavior Web-based Survey (KYRBS). We established standard cutoffs of 20 ng/mL, 30 ng/mL, 50 ng/mL, and 100 ng/mL to compare the results of UCC testing with those of self-reporting methods. The KYRBS demonstrated an overall current smoking rate of 12.25%, while the KNHANEs measured an overall rate of 9.63%. The UCC20 reported the highest current smoking rate at 25.6% overall. Methods that detected a lower prevalence of current smoking, in declining order, were the UCC30, UCC50, UCC100, online survey, and the KNHANEs (SR). The results of this study show that online surveys on smoking administered to adolescents have fewer false responses compared with the KNHANEs (SR). However, compared with UCC testing, online surveys still significantly underreport adolescent smoking rates. PMID:25556217

    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.

    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.

    Background Maximising response rates to neurodevelopmental follow-up is a key challenge for paediatric researchers. We have investigated the use of telephone interviews and online questionnaires to improve response rates, reduce non-response bias, maintain data completeness and produce unbiased outcomes compared with postal questionnaires when assessing neurodevelopmental outcomes at 2 years. Methods A prospective cohort study of babies born ?32 weeks gestation. Neurodevelopmental outcomes were assessed at 2 years of age using a parent questionnaire completed via post, telephone or online. Relative Risks with 95% confidence intervals (RR; 95% CI) were calculated to identify participant characteristics associated with non-response and questionnaire response mode (postal vs. telephone/online). The proportion of missing data and prevalence of adverse outcomes was compared between response modes using generalized linear models. Results Offering telephone/online questionnaires increased the study response rate from 55% to 60%. Telephone/online responders were more likely to be non-white (RR 1.6; [95% CI 1.1, 2.4]), non-English speaking (1.6; [1.0, 2.6]) or have a multiple birth (1.6; [1.1, 2.3]) than postal responders. There were no significant differences in the prevalence of adverse neurodevelopmental outcomes between those who responded via post vs. telephone/online (1.1; [0.9, 1.4]). Where parents attempted all questionnaire sections, there were no significant differences in the proportion of missing data between response modes. Conclusions Where there is sufficient technology and resources, offering telephone interviews and online questionnaires can enhance response rates and improve sample representation to neurodevelopmental follow-up, whilst maintaining data completeness and unbiased outcomes.

    OBJECTIVES--To design a questionnaire for the identification and assessment of severity of back pain for epidemiological purposes, and gain preliminary experience of its use. METHODS--A group of specialists, experienced in the epidemiology and clinical assessment of back pain, designed the questionnaire, and tested it individually. It was also given cross sectionally by interview to a population of male coal mine workers. RESULTS--The questionnaire comprised a maximum of 12 questions on the presence, radiation, frequency, and severity of back pain with reference to difficulty with specific activities, interference with normal work, and absence from work. 471 coal miners answered the questionnaire (66% of those invited). 56% (265 men) of the responders reported pain or ache in the back during the previous 12 months, and the incidence of first ever attacks during the same period was reported to be 34%. 69% reported having had back pain at some time. The responses to the questionnaire were partially validated by comparison with certified sickness absence for two days or more attributed to back pain. In men who were symptomatic in the previous 12 months, for the question relating to absence from work because of back pain, the sensitivity was 82% and specificity was 84%. CONCLUSION--The questionnaire is easy to administer and generates clear cut data that could be useful for epidemiological or screening purposes. Preliminary, limited, studies of its validity are reasonably encouraging, although further validation is required. It is hoped that researchers will find the questionnaire useful, will extend its validation, and continue to develop it. PMID:7849853

    Questionnaires concerning subjective health status are an important element of rehabilitation research. The appraisal of the quality of these instruments mostly relies on quantitative psychometric analyses. However, these analyses do not explicitly reveal whether or how respondents understand questionnaire content. Over the past few years cognitive interviewing has been increasingly used in questionnaire design and validation. It serves to identify potentially problematic questions, ambiguities and difficulties which could lead to unintended answers. It analyses whether the answers given by respondents represent the intended meaning of the question. Findings derived from cognitive interviewing serve to improve new and further validate well-established questionnaires.The 4-stage model of the survey response process by Tourangeau provides a conceptual basis for cognitive interviewing. The 2 most prominent methods of cognitive interviewing are think aloud and verbal probing. Various authors give recommendations on executing cognitive interviews but almost no recommendations exist on the -indications of the different methods.Potential applications of cognitive interviewing go beyond questionnaire design and improvement. Due to its origin in cognitive science it can also be used to resolve substantive questions, e.?g. concerning reasons for discrepancies between the results of 2 different methods of measuring change.

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

    The Nephrology Quiz and Questionnaire (NQ&Q) remains an extremely popular session for attendees of the Annual Meeting of the American Society of Nephrology. As in past years, the conference hall of the 2013 meeting was overflowing with interested audience members. Topics covered by expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplantation. Complex cases representing each of these categories, along with single best answer questions, were prepared by a panel of experts. Before the meeting, program directors of United States nephrology training programs answered questions through an Internet-based questionnaire. A new addition to the NQ&Q was participation in the questionnaire by nephrology fellows. To review the process, members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. Their answers are compared in real time using audience response devices with the answers of nephrology fellows and training program directors. The correct and incorrect answers are then briefly discussed after the audience responses and the results of the questionnaire are displayed.

    The aim of this study is to develop a questionnaire that can observe empathy in group psychoanalytic psychotherapy and examine the structure of its factors. A questionnaire comprised of 160 items in five-point Likert-type scale was developed through analysis of communication and interaction related to empathizing during group sessions. The questionnaire was applied on 256 patients from 40 therapy groups in 9 cities in Croatia. All 20 group analysts are trained in the Institute for Group Analysis in Zagreb. The patients were selected based on group analysis criteria. After item discrimination and principal component analysis limited to five factors were assessed, 80 items were isolated, 20 of which made a control scale for socially desirable responses. Two parallel questionnaire forms were developed: Group-Analysis-Empathy 1 (GA-Em1) and Group-Analysis-Empathy 2 (GA-Em2). A new, reliable and valid questionnaire for empathy observation employable in group psychotherapy was designed. The following factors were isolated by means of factor analysis: 1. Emotional disclosure and sensibility; 2. Containing and metabolizing; 3. Immersion; 4. Resonance and responsiveness; 5. Insight. A new questionnaire on empathy in group-analytical psychotherapy can measure the capacity for emotional communication among group members and between the group and the group analyst - conductor.

    Study Objectives: Developed the Cleveland Adolescent Sleepiness Questionnaire (CASQ), a brief, self-completed instrument to measure excessive daytime sleepiness in adolescents. Design: Cross-sectional analysis. Participants: A subsample of 411 adolescents 11–17 years of age recruited from area schools, churches, and “control” participants in a sleep disordered breathing cohort study; a second subsample of 62 adolescents with diagnosed sleep disordered breathing also participating in the sleep disordered breathing study. Measurements: Participants completed the CASQ along with two other available measures of daytime sleepiness and other sleep parameters (sleep duration on school nights, sleep duration on non-school nights, and sleep debt, defined as non-school night sleep duration minus school-night sleep duration). Demographic information was obtained from a caregiver-completed questionnaire. The CASQ was developed using exploratory factor analysis, followed by confirmatory factor analysis using structural equation modeling techniques. Results: Goodness-of-fit measures for the final 16-item scale structure ranged from good to excellent. The CASQ's internal consistency was good (? = 0.89). Correlations between the CASQ, two other measures of daytime sleepiness, and sleep parameters gave preliminary evidence of the CASQ's construct validity. Conclusion: The CASQ shows promise as a valid measure of daytime sleepiness in adolescents. Citation: Spilsbury JC; Drotar D; Rosen CL et al.

    Aim To explore the factor structure, reliability, and potential usefulness of a patient safety climate questionnaire in UK health care. Setting Four acute hospital trusts and nine primary care trusts in England. Methods The questionnaire used was the 27 item Teamwork and Safety Climate Survey. Thirty three healthcare staff commented on the wording and relevance. The questionnaire was then sent to 3650 staff within the 13 NHS trusts, seeking to achieve at least 600 responses as the basis for the factor analysis. 1307 questionnaires were returned (36% response). Factor analyses and reliability analyses were carried out on 897 responses from staff involved in direct patient care, to explore how consistently the questions measured the underlying constructs of safety climate and teamwork. Results Some questionnaire items related to multiple factors or did not relate strongly to any factor. Five items were discarded. Two teamwork factors were derived from the remaining 11 teamwork items and three safety climate factors were derived from the remaining 11 safety items. Internal consistency reliabilities were satisfactory to good (Cronbach's alpha ?0.69 for all five factors). Conclusions This is one of the few studies to undertake a detailed evaluation of a patient safety climate questionnaire in UK health care and possibly the first to do so in primary as well as secondary care. The results indicate that a 22 item version of this safety climate questionnaire is useable as a research instrument in both settings, but also demonstrates a more general need for thorough validation of safety climate questionnaires before widespread usage.

    This paper characterizes the effective beams, the effective beam window functions and the associated errors for the Planck High Frequency Instrument (HFI) detectors. The effective beam is theangular response including the effect of the optics, detectors, data processing and the scan strategy. The window function is the representation of this beam in the harmonic domain which is required to recover an unbiased measurement of the cosmic microwave background angular power spectrum. The HFI is a scanning instrument and its effective beams are the convolution of: a) the optical response of the telescope and feeds; b) the processing of the time-ordered data and deconvolution of the bolometric and electronic transfer function; and c) the merging of several surveys to produce maps. The time response transfer functions are measured using observations of Jupiter and Saturn and by minimizing survey difference residuals. The scanning beam is the post-deconvolution angular response of the instrument, and is characterized with observations of Mars. The main beam solid angles are determined to better than 0.5% at each HFI frequency band. Observations of Jupiter and Saturn limit near sidelobes (within 5°) to about 0.1% of the total solid angle. Time response residuals remain as long tails in the scanning beams, but contribute less than 0.1% of the total solid angle. The bias and uncertainty in the beam products are estimated using ensembles of simulated planet observations that include the impact of instrumental noise and known systematic effects. The correlation structure of these ensembles is well-described by five error eigenmodes that are sub-dominant to sample variance and instrumental noise in the harmonic domain. A suite of consistency tests provide confidence that the error model represents a sufficient description of the data. The total error in the effective beam window functions is below 1% at 100 GHz up to multipole ? ~ 1500, and below 0.5% at 143 and 217 GHz up to ? ~ 2000.

    Purpose To determine if respondents share researchers’ understandings of concepts and questions frequently used in the assessment of usual physical activity behavior. Methods As part of On the Move, a study aimed at reducing measurement error in self-reported physical activity (PA), we conducted cognitive interviews with 19 men and 21 women, ages 45-65, regarding their responses to the PA questionnaires used in two large, population-based studies, LACE (Life After Cancer Epidemiology) and CMH (California Men’s Health Study). One questionnaire asks about the frequency, duration, and perceived intensity of a range of specific activities in several different domains over the past 12 months. The second questionnaire asks about frequency and duration of specific, mostly recreational activities, grouped by intensity (i.e., moderate or vigorous) over the past 3 months. We used verbal probing techniques to allow respondents to describe their thought processes as they completed the questionnaires. All interviews were tape-recorded and transcribed, and the transcripts were then analyzed using standard qualitative methods. Results Cognitive interviews demonstrated that a sizable number of respondents understood “intensity” in terms of emotional or psychological intensity, rather than physical effort. As a result, the perceived intensity with which a participant reported doing a specific activity often bore little relationship to the MET value of that activity. Additionally, participants often counted the same activity more than once, overestimated work-related PA, and understood activities that were grouped together in a single category to be definitive lists rather than examples. Conclusion Cognitive interviews revealed significant gaps between respondents’ interpretations of some physical activity questions and researchers’ assumptions about what those questions were intended to measure. Some sources of measurement error in self-reported PA may be minimized by additional research that focuses on the cognitive processes required to respond to PA questionnaires. PMID:19127192

    Outcome questionnaires are increasingly used in the current medical practice. Patient reported outcomes serve as an essential and perhaps more relevant means for assessing patients’ response to treatment than clinical measures alone. Many of the procedures performed in plastic surgery are associated with aesthetic outcomes, therefore it is pertinent to thoroughly understand the patient’s perspective of achieved results. Surgeons need to possess the knowledge and skills about outcomes assessments and understand how to apply them to improve quality of care delivered based on evidence. This paper discusses the appropriate use of outcome questionnaires to rigorously evaluate treatment methods based on patient satisfaction and the outcome measurement instruments frequently used in plastic surgery.

    Purpose The aim of the current study is to test the validity and reliability of the Shame Questionnaire among traumatized girls in Lusaka, Zambia. Methods The Shame Questionnaire was validated through both classical test and item response theory methods. Internal reliability, criterion validity and construct validity were examined among a sample of 325 female children living in Zambia. Sub-analyses were conducted to examine differences in construct validity among girls who reported sexual abuse and girls who did not. Results All girls in the sample were sexually abused, but only 61.5% endorsed or reported that sexual abuse had occurred. Internal consistency was very good among the sample with alpha = .87. Criterion validity was demonstrated through a significant difference of mean Shame Questionnaire scores between girls who experienced 0–1 trauma events and more than one traumatic event, with higher mean Shame Questionnaire scores among girls who had more than one traumatic event (p = .004 for 0–1 compared to 2 and 3 events and p = .016 for 0–1 compared to 4+ events). Girls who reported a history of witnessing or experiencing physical abuse had a significantly higher mean Shame Questionnaire score than girls who did not report a history of witnessing or experiencing physical abuse (p<.0001). There was no significant difference in mean Shame Questionnaire score between girls who reported a sexual abuse history and girls who did not. Exploratory factor analysis indicated a two-factor model of the Shame Questionnaire, with an experience of shame dimension and an active outcomes of shame dimension. Item response theory analysis indicated adequate overall item fit. Results also indicate potential differences in construct validity between girls who did and did not endorse sexual abuse. Conclusions This study suggests the general utility of the Shame Questionnaire among Zambian girls and demonstrates the need for more psychometric studies in low and middle income countries.

    OBJECTIVES: (a) To determine both the frequency of injecting inside prison and use of sterilising tablets to clean needles in the previous four weeks; (b) to assess the efficiency of random mandatory drugs testing at detecting prisoners who inject heroin inside prison; (c) to determine the percentage of prisoners who had been offered vaccination against hepatitis B. DESIGN: Cross sectional willing anonymous salivary HIV surveillance linked to a self completion risk factor questionnaire. SETTING: Lowmoss prison, Glasgow, and Aberdeen prison on 11 and 30 October 1996. SUBJECTS: 293 (94%) of all 312 inmates at Lowmoss and 146 (93%) of all 157 at Aberdeen, resulting in 286 and 143 valid questionnaires. MAIN OUTCOME MEASURES: Frequency of injecting inside prison in the previous four weeks by injector inmates who had been in prison for at least four weeks. RESULTS: 116 (41%) Lowmoss and 53 (37%) Aberdeen prisoners had a history of injecting drug use but only 4% of inmates (17/395; 95% confidence interval 2% to 6%) had ever been offered vaccination against hepatitis B. 42 Lowmoss prisoners (estimated 207 injections and 258 uses of sterilising tablets) and 31 Aberdeen prisoners (229 injections, 221 uses) had injected inside prison in the previous four weeks. The prisons together held 112 injector inmates who had been in prison for more than four weeks, of whom 57 (51%; 42% to 60%) had injected in prison in the past four weeks; their estimated mean number of injections was 6.0 (SD 5.7). Prisoners injecting heroin six times in four weeks will test positive in random mandatory drugs testing on at most 18 days out of 28. CONCLUSIONS: Sterilising tablets and hepatitis B vaccination should be offered to all prisoners. Random mandatory drugs testing seriously underestimates injector inmates' harm reduction needs.

    In the early 1990s a multicentre survey on asthma was performed on the young adult population (European Community Respiratory Health Survey - ECRHS). This study is to be repeated in order to estimate changes in the prevalence of asthma-like symptoms during the last decade and to assess the social and economic costs of the disease and their variations among countries. The self-administered questionnaire devised for this purpose is a two-page questionnaire. The first page contains the same items as those used in the first survey with four additional questions related to: 1) the frequency and severity of asthma attacks; 2) the presence of chronic bronchitis; 3) smoking habits; and 4) a visual analogue scale assessing perception of outdoor pollution. The second page aims to collect information regarding the direct and indirect costs of asthma. The influence of the length of the questionnaire on the response rate was assessed in a pilot study in Italy. Two random samples of 150 subjects received either the one-page questionnaire (first page) or the two-page questionnaire. The response rate was compared with that obtained from the first postal wave in the 1991-1992 survey. Although the response rate was unchanged when using the one-page questionnaire (45% versus 45%), it decreased by 7% when the two-page questionnaire was used (38% versus 45%). On the basis of these results, no problem should arise if four more questions are added to the one-page questionnaire. The slight reduction in the response rate of the two-page questionnaire is worrying but could be corrected by the use of telephone interviews. PMID:10596688

    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.

    BACKGROUND: There are several questionnaires available to assess quality of life in breast cancer, however the choice of the best questionnaire often does not take into account the adequacy of these questionnaires' measurement properties. OBJECTIVE: To test the measurement properties of two generic quality of life questionnaires and one quality of life questionnaire specific for women with breast cancer. METHOD: We assessed 106 women after surgery for breast cancer. The assessment included application of the SF-36, WHOQOL-bref, and FACT-B+4 questionnaires as well as the Global Perceived Effect and Pain Numerical Rating scales. The participants were interviewed on three occasions to investigate internal consistency, floor and ceiling effects, construct validity, reproducibility, and responsiveness. RESULTS: Most of the instruments' domains showed adequate internal consistency (Cronbach's alpha varying from 0.66 to 0.91). Reliability varied from poor to substantial (ICC2,1 between 0.39 and 0.87) and agreement varied from negative to very good. The SF-36 presented doubtful agreement and showed floor and ceiling effects in three domains. The domains of the generic questionnaires presented moderate to good correlation with the FACT-B+4 (Pearson varying from 0.31 to 0.69). The internal responsiveness varied from small to large (ES varying from -0.26 to 0.98) and external responsiveness was found in only some of the instruments' domains. CONCLUSIONS: Most of the measurement properties tested for the WHOQOL-bref and FACT-B+4 were adequate as was their ability to assess quality of life in women with breast cancer. The SF-36 showed inadequacy in agreement and floor and ceiling effects and should not be used in women with breast cancer. PMID:25075998

    [Purpose] Currently, there are a limited number of amputee-specific instruments for measuring prosthesis-related quality of life with good psychometric properties in Turkey. This study translated the Prosthetic Evaluation Questionnaire to Turkish and analyzed as well as discussed its construct validity and internal consistency. [Subjects and Methods] The Prosthetic Evaluation Questionnaire was adapted for use in Turkish by forward/backward translation. The final Turkish version of this questionnaire was administered to 90 unilateral amputee patients. Second evaluation was possible in 83 participants within a median 28 day time period. [Results] Point estimates for the intraclass correlation coefficient ranged from 0.69 to 0.89 for all 9 Prosthetic Evaluation Questionnaire scales, indicating good correlation. Overall Cronbach’s alpha coefficients ranged from 0.64 to 0.92, except for the perceived response subscale of 0.39. The ambulation subscale was correlated with the physical functioning subscales of Short Form-36 (SF-36) (r=0.48). The social burden subscale score of the Prosthetic Evaluation Questionnaire was correlated with social functioning subscales of SF-36 (r= 0.63). [Conclusion] The Turkish version of the Prosthetic Evaluation Questionnaire is a valid and reliable tool for implementation in the Turkish unilateral amputee population. PMID:26180296

    U-shaped response has been frequently encountered in various biological areas including epidemiology, toxicology, and oncology. Despite its frequent observation, the theory of U-shaped response has been crippled by the lack of a robust mechanism underlying and incomplete in vitro and in vivo correlation. In the present study, a novel mechanism is provided for a U-shaped response, based on the findings of agonist-induced vasomotor tone change affected by menadione (MEN) (synthetic vitamin K(3)), a reactive oxygen species generator, and arsenic, an environmental pollutant, which showed typical U-shaped responses in both in vitro aortic contractile response and in vivo blood pressure. U-shaped responses by MEN and arsenic were a combined result from heterogenic susceptibilities and responses of multiple target cells composing blood vessels, that is, endothelium and smooth muscle. Notably, endothelium, a regulator of vasomotor tone, was primarily affected by low-dose stimuli, whereas smooth muscle, an effector of vascular contraction, was affected later by high-dose. The dysfunction of smooth muscle was produced by high-dose MEN-induced hydrogen peroxide, resulting in the attenuation of vascular contractile reactivity, whereas low-dose MEN-induced superoxide led to the quenching of vasodilatory nitric oxide in endothelial cells, resulting in the enhancement of vasoconstriction. This mechanistic theory, the difference in susceptibilities and responses to a common stimulus between regulator and effector components of a system, could give a new insight into the explanation of various U-shaped responses and provide a new evidence for the need of the risk assessment of toxicants with a wider dose range.

    We developed a Dry Eye Screening Questionnaire for the Dry Eye Epidemiology Projects (DEEP), a proposed large epidemiologic study. All persons who screen positive and a small sample of those who screen negative are to be invited for a diagnostic examination. Containing 19 questions, of which only 14 were used in the analysis, the questionnaire takes only a few minutes to administer on the telephone. To construct a discriminator function and thus a ROC curve, we used stepwise multiple regression on screening responses from a clinic series of 77 cases and 79 controls. Stepwise regression may incorporate into the predictor equation variables whose relation to the predicted is only accidental. Further, misclassification rates are underestimated by the resubstitution method, in which the proportion misclassified is obtained from the same dataset in which the discriminator function was fitted. To counter these problems, we randomly divided the data in half. We chose as predictors only those variables (Dry and Irritated) selected by stepwise regression in both data halves. We estimated unbiased misclassification rates using the unbiased test set method, in which the discriminator is fitted in one data half, and misclassification rates are calculated in the other half. Comparison of ROC curves arising from resubstitution and test set estimates indicates that resubstitution bias in misclassification rate estimation is negligible in our data. A resubstitution estimate made on the entire data is thus preferred. The resulting sensitivity/specificity values are reasonably high (e.g., 60%/94%), suggesting that the questionnaire will be a useful screening tool in the DEEP study. A second discriminator using the sum of all 14 responses is similar in its misclassification characteristics to the first discriminator. A second potentially significant error, arising from applying results from a clinical series to a general population, will be investigated as survey results in DEEP become available. PMID:9634971

    Purpose To evaluate and refine a newly developed instrument, the Student Refractive Error and Eyeglasses Questionnaire (SREEQ), designed to measure the impact of uncorrected and corrected refractive error on vision-related quality of life (VRQoL) in school-aged children. Methods. A 38 statement instrument consisting of two parts was developed: Part A relates to perceptions regarding uncorrected vision and Part B relates to perceptions regarding corrected vision and includes other statements regarding VRQoL with spectacle correction. The SREEQ was administered to 200 Native American 6th through 12th grade students known to have previously worn and who currently require eyeglasses. Rasch analysis was conducted to evaluate the functioning of the SREEQ. Statements on Part A and Part B were analyzed to examine the dimensionality and constructs of the questionnaire, how well the items functioned, and the appropriateness of the response scale used. Results Rasch analysis suggested two items be eliminated and the measurement scale for matching items be reduced from a 4-point response scale to a 3-point response scale. With these modifications, categorical data were converted to interval level data, to conduct an item and person analysis. A shortened version of the SREEQ was constructed with these modifications, the SREEQ-R, which included the statements that were able to capture changes in VRQoL associated with spectacle wear for those with significant refractive error in our study population. Conclusions While the SREEQ Part B appears to be a have less than optimal reliability to assess the impact of spectacle correction on VRQoL in our student population, it is also able to detect statistically significant differences from pretest to posttest on both the group and individual levels to show that the instrument can assess the impact that glasses have on VRQoL. Further modifications to the questionnaire, such as those included in the SREEQ-R, could enhance its functionality. PMID:24811844

  1. Development of the young spine questionnaire

    PubMed Central

    2013-01-01

    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

    2013-01-01

    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

    2011-01-01

    Background: Colleges and universities are becoming increasingly accountable for teaching outcomes in order to meet rigorous accreditation standards. Job satisfaction (JS) seems more difficult to measure in the academic field in view of the complexity of roles, duties and responsibilities. Objectives: To compile and determine the psychometric properties of a proposed Academic Job Satisfaction Questionnaire (AJSQ) suitable for university faculty, and amenable to future upgrading. Materials and Methods: A 46-item five-option Likert-type draft questionnaire on JS was distributed for anonymous self-reporting by all the academic staff of five colleges in University of Dammam (n=340). The outcome measures were (1) factor analysis of the questionnaire items, (2) intra-factor ?-Coefficient of Internal Consistency Reliability, (3) inter-factor correlations, (4) comparison of psychometric properties in separately analyzed main faculty subgroups. Results: The response rate was 72.9 percent. Factor analysis extracted eight factors which conjointly explained 60.3 percent of the variance in JS. These factors, in descending order of eigenvalue, were labeled “Authority”, “Supervision”, “Policies and Facilities”, “My Work Itself”, “Interpersonal Relationships”, “Commitment”, “Salary” and “Workload”. Cronbach's-? ranged from 0.90 in Supervision to 0.63 in Salary and Workload. All inter-factor correlations were positive and significant, ranging from 0.65 to 0.23. The psychometric properties of the instrument in separately analyzed subgroups divided by sex, nationality, college and clinical duties produced fairly comparable findings. Conclusion: The AJSQ demonstrated good overall psychometric properties in terms of construct validity and internal consistency reliability in both the overall sample and its separately analyzed subgroups. Recommendation: To replicate these findings in larger multicenter samples of academic staff. PMID:21694952

  6. The negative affect repair questionnaire: factor analysis and psychometric evaluation in three samples

    PubMed Central

    2013-01-01

    Background Negative affect and difficulties in its regulation have been connected to several adverse psychological consequences. While several questionnaires exist, it would be important to have a theory-based measure that includes clinically relevant items and shows good psychometric properties in healthy and patient samples. This study aims at developing such a questionnaire, combining the two Gross [1] scales Reappraisal and Suppression with an additional response-focused scale called Externalizing Behavioral Strategies covering clinically relevant items. Methods The samples consisted of 684 students (mean age?=?23.3, SD?=?3.5; 53.6% female) and 369 persons with mixed mental disorders (mean age?=?36.0 SD?=?14.6; 71.2% female). Items for the questionnaire were derived from existing questionnaires and additional items were formulated based on suggestions by clinical experts. All items start with “When I don’t feel well, in order to feel better…”. Participants rated how frequently they used each strategy on a 5-point Likert scale. Confirmatory Factor Analyses were conducted to verify the factor structure in two separate student samples and a clinical sample. Group comparisons and correlations with other questionnaires were calculated to ensure validity. Results After modification, the CFA showed good model fit in all three samples. Reliability scores (Cronbach’s ?) for the three NARQ scales ranged between .71 and .80. Comparisons between students and persons with mental disorders showed the postulated relationships, as did comparisons between male and female students and persons with or without Borderline Personality Disorder. Correlations with other questionnaires suggest the NARQ’s construct validity. Conclusions The results indicate that the NARQ is a psychometrically sound and reliable measure with practical use for therapy planning and tracking of treatment outcome across time. We advocate the integration of the new response-focused strategy in the Gross’s model of emotion regulation. PMID:23302222

    2012-01-01

    BACKGROUND: A validated health-related quality of life questionnaire in chronic obstructive pulmonary disease (COPD) with advantages of both generic- and disease-specific questionnaires is needed to capture patients’ perspectives of severity and impact of the disease. The McGill COPD questionnaire was created to include these advantages in English and French. It assesses three domains: symptoms, physical function and feelings with 29 items (12 from the 36-item Short-Form Health Survey with 17 from the previously developed COPD-specific module). OBJECTIVE: To evaluate the psychometric properties of this newly developed hybrid questionnaire in subjects with COPD. METHODS: Data from a multicentre, prospective cohort study involving four hospitals with COPD subjects undergoing pulmonary rehabilitation were used. Patient evaluations included health-related quality of life (the new McGill COPD questionnaire, the St Georges Respiratory Questionnaire and the 36-item Short-Form Health Survey) and pulmonary function tests pre-and postrehabilitation. Reliability, validity and responsiveness were tested. RESULTS: The study included 246 COPD subjects (111 females) with a mean age of 66 years, 87% ex- and 8% current smokers (mean 61 pack-years) and mean forced expiratory volume in 1 s of 1.12 L (Global initiative for chronic Obstructive Lung Disease stages: 2, 27%; 3, 33%; and 4, 37%). Missing data were <2% and floor and ceiling effects were <5%. Internal consistency (Cronbach’s alpha) was 0.68 to 0.82. Test-retest reliability (intracorrelation coefficients) ranged from 0.74 to 0.96 for the sub-scales, and 0.95 for the total score. Correlation with the St George’s Respiratory Questionnaire was moderately high (r=? 0.88 [95% CI ?0.91 to ?0.84]), consistent with the a priori hypothesis for convergent validity. The effect size was 0.33 (pre-postrehabilitation mean score difference = 6), suggesting a small to moderate change. CONCLUSIONS: The new McGill COPD questionnaire showed high internal consistency, test-retest reliability, validity and moderate responsiveness in COPD subjects. PMID:23248800

    Purpose To adapt the College of Optometrist in Vision Development (COVD-QOL) questionnaire as a vision screening tool for primary school children. Methods An interview session was conducted with children, teachers or guardians regarding visual symptoms of 88 children (45 from special education classes and 43 from mainstream classes) in government primary schools. Data was assessed for response categories, fit items (infit/outfit: 0.6–1.4) and separation reliability (item/person: 0.80). The COVD-QOL questionnaire results were compared with vision assessment in identifying three categories of vision disorders: reduce visual acuity, accommodative response anomaly and convergence insufficiency. Analysis on the screening performance using the simplified version of the questionnaire was evaluated based on receiver-operating characteristic analysis for detection of any type of target conditions for both types of classes. Predictive validity analysis was used a Spearman rank correlation (>0.3). Results Two of the response categories were underutilized and therefore collapsed to the adjacent category and items were reduced to 14. Item separation reliability for the simplified version of the questionnaire was acceptable (0.86) but the person separation reliability was inadequate for special education classes (0.79) similar to mainstream classes (0.78). The discriminant cut-off score of 9 (mainstream classes) and 3 (special education classes) from the 14 items provided sensitivity and specificity of (65% and 54%) and (78% and 80%) with Spearman rank correlation of 0.16 and 0.40 respectively. Conclusion The simplified version of COVD-QOL questionnaire (14-items) performs adequately among children in special education classes suggesting its suitability as a vision screening tool.

    Well-designed screening assessment instruments that can evaluate child development in public daycare centers represent an important resource to help improve the quality of these programs, as an early detection method for early developmental delay. The Ages and Stages Questionnaire, 3rd edition (ASQ-3), comprises a series of 21 questionnaires designed to screen developmental performance in the domains of communication, gross motor skills, fine motor skills, problem solving, and personal-social ability in children aged 2 to 66 months. The purpose of the present work was to translate and adapt all of the ASQ-3 questionnaires for use in Brazilian public child daycare centers and to explore their psychometric characteristics with both Classical Test Theory and Rating Scale analyses from the Rasch model family. A total of 18 Ages & Stages Questionnaires - Brazilian translation (ASQ-BR) questionnaires administered at intervals from 6 to 60 months of age were analyzed based on primary caregiver evaluations of 45,640 children distributed in 468 public daycare centers in the city of Rio de Janeiro. The results indicated that most of the ASQ-BR questionnaires had adequate internal consistency. Exploratory factor analyses yielded a one-factor solution for each domain of all of the ASQ-BR questionnaires. The only exception was the personal-social domain in some of the questionnaires. Item Response Theory based on Rating Scale analysis (infit and outfit mean squares statistics) indicated that only 44 of 540 items showed misfit problems. In summary, the ASQ-BR questionnaires are psychometrically sound developmental screening instruments that can be easily administered by primary caregivers. PMID:23507472

    The Nephrology Quiz and Questionnaire (NQ&Q) remains an extremely popular session for attendees of the annual meeting of the American Society of Nephrology. As in past years, the conference hall was overflowing with interested audience members. Topics covered by expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplantation. Complex cases representing each of these categories along with single-best-answer questions were prepared by a panel of experts. Prior to the meeting, program directors of United States nephrology training programs answered questions through an Internet-based questionnaire. A new addition to the NQ&Q was participation in the questionnaire by nephrology fellows. To review the process, members of the audience test their knowledge and judgment on a series of case-oriented questions prepared and discussed by experts. Their answers are compared in real time using audience response devices with the answers of nephrology fellows and training program directors. The correct and incorrect answers are then briefly discussed after the audience responses, and the results of the questionnaire are displayed. This article recapitulates the session and reproduces its educational value for the readers of CJASN. Enjoy the clinical cases and expert discussions. PMID:24558051

    Background This study was conducted to develop a questionnaire in order to evaluate knowledge, attitude and practice (KAP) of the faculty members and students toward plagiarism. Methods: A KAP study was conducted from June to October 2011 enrolling 390 volunteers anonymously (response rate 96%). The questionnaire included the following four parts: (a) general characteristics like gender, academic degree and education level; (b) nine questions regarding knowledge (Min=0, Max=9); (c) nine questions regarding attitude (Min=9, Max=27); and (d) eight questions regarding practice (Min=0, Max=8). A pilot study was conducted to assess reliability of the questions regarding knowledge and attitude. Cronbach’s alpha coefficient for the knowledge and attitude questions was 0.70 and 0.74 respectively. Results: The overall prevalence of at least once plagiarism commission was 38% (SD=0.035). The overall mean score of knowledge, attitude and practice was 5.94 (SD=1.66), 24.12 (SD=2.99), and 0.66 (SD=1.15) respectively. Knowledge of plagiarism was significantly higher among higher academic degrees and females. Their negative attitude toward plagiarism was stronger too. No statistically significant difference regarding plagiarism commission was observed among different academic degrees in both sexes. According to linear regression analysis, plagiarism commission decreased 13% per one unit increase in score of knowledge (P=0.005) and 16% per one unit increase in score of attitude (P<0.001). Conclusions: This knowledge, attitude, and practice (KAP) questionnaire was developed as a standard tool in order to assess perception of subjects toward plagiarism and to estimate the prevalence and the type of plagiarism commission.

    2011-01-01

    As more Spanish speaking immigrants participate in and become the focus of research studies, questions arise about the appropriateness of existing research tools. Questionnaires have often been adapted from English language instruments and tested among college-educated Hispanic-Americans. Little has been written regarding the testing and evaluation of research tools among less educated Latino immigrants. The purpose of this study was to evaluate and revise a battery of Spanish-language questionnaires for an intervention among immigrant Hispanic women. A three-step process was used to evaluate, adapt and test Spanish versions of the Self-Efficacy and Exercise Habits Survey, an abbreviated version of the Hispanic Stress Inventory-Immigrant version and the Latina Values Scale. The revised tools demonstrated acceptable validity and reliability. The adaptations improved the readability of the tools, resulting in a higher response rate, less missing data and fewer extreme responses. Psychometric limitations to the adaptation of Likert scales are discussed. PMID:22030592

    2008-01-01

    Background The valid and reliable measurement of health service utilization, productivity losses and consequently total disease-related costs is a prerequisite for health services research and for health economic analysis. Although administrative data sources are usually considered to be the most accurate, their use is limited as some components of utilization are not systematically captured and, especially in decentralized health care systems, no single source exists for comprehensive utilization and cost data. The aim of this study was to develop and test a questionnaire for the measurement of disease-related costs for patients after an acute cardiac event (ACE). Methods To design the questionnaire, the literature was searched for contributions to the assessment of utilization of health care resources by patient-administered questionnaires. Based on these findings, we developed a retrospective questionnaire appropriate for the measurement of disease-related costs over a period of 3 months in ACE patients. Items were generated by reviewing existing guidelines and by interviewing medical specialists and patients. In this study, the questionnaire was tested on 106 patients, aging 35–65 who were admitted for rehabilitation after ACE. It was compared with prospectively measured data; selected items were compared with administrative data from sickness funds. Results The questionnaire was accepted well (response rate = 88%), and respondents completed the questionnaire in an average time of 27 minutes. Concordance between retrospective and prospective data showed an intraclass correlation (ICC) ranging between 0.57 (cost of medical intake) and 0.9 (hospital days) with the other main items (physician visits, days off work, medication) clustering around 0.7. Comparison between self-reported and administrative data for days off work and hospitalized days were possible for n = 48. Respective ICCs ranged between 0.92 and 0.94, although differences in mean levels were observed. Conclusion The questionnaire was accepted favorably and correlated well with alternative measurement approaches. This first assessment showed promising characteristics of this questionnaire in different aspects of validity for patients with ACE. However, additional research and more extensive tests in other patient groups would be worthwhile. PMID:18803845

    Background Hierarchical scales are useful in understanding the structure of underlying latent traits in many questionnaires. The Attitudes to Ageing Questionnaire (AAQ) explored the attitudes to ageing of older people themselves, and originally described three distinct subscales: (1) Psychosocial Loss (2) Physical Change and (3) Psychological Growth. This study aimed to use Mokken analysis, a method of Item Response Theory, to test for hierarchies within the AAQ and to explore how these relate to underlying latent traits. Methods Participants in a longitudinal cohort study, the Lothian Birth Cohort 1936, completed a cross-sectional postal survey. Data from 802 participants were analysed using Mokken Scaling analysis. These results were compared with factor analysis using exploratory structural equation modelling. Results Participants were 51.6% male, mean age 74.0 years (SD 0.28). Three scales were identified from 18 of the 24 items: two weak Mokken scales and one moderate Mokken scale. (1) ‘Vitality’ contained a combination of items from all three previously determined factors of the AAQ, with a hierarchy from physical to psychosocial; (2) ‘Legacy’ contained items exclusively from the Psychological Growth scale, with a hierarchy from individual contributions to passing things on; (3) ‘Exclusion’ contained items from the Psychosocial Loss scale, with a hierarchy from general to specific instances. All of the scales were reliable and statistically significant with ‘Legacy’ showing invariant item ordering. The scales correlate as expected with personality, anxiety and depression. Exploratory SEM mostly confirmed the original factor structure. Conclusions The concurrent use of factor analysis and Mokken scaling provides additional information about the AAQ. The previously-described factor structure is mostly confirmed. Mokken scaling identifies a new factor relating to vitality, and a hierarchy of responses within three separate scales, referring to vitality, legacy and exclusion. This shows what older people themselves consider important regarding their own ageing. PMID:24892302

    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.

  11. 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

    2013-01-01

    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

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

    PubMed Central

    2011-01-01

    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

    The response of freshwater zooplankton communities to two chemical stressors, acidification and pesticide contamination, were investigated in a review of published research results. The objective was to test Odum's predictions (Odum, 1985) that in response to stress, both the average body size of organisms and their efficiency in utilizing resources are reduced. Acidification and pesticide contamination were both found to favor dominance by small cladorecans and rotifers, the smallest zooplankton taxa. This finding was consistent with Odum's predictions, however, there were exceptions to the trend. The dominance of small taxa may be due to rapid reproductive rates, physiological tolerance, development with few transitions through sensitive stages (eg. post-molting), or to the great richness of small species. Regardless of the mechanism, there is evidence that when acidification and pesticide contamination result in small zooplankton dominance, the efficiency of carbon and energy transfer from algae to zooplankton is reduced. This finding is also consistent with Odum's predictions. PMID:15091777

  18. Development and psychometric properties of a questionnaire to assess barriers to feeding critically ill patients

    PubMed Central

    2013-01-01

    Background To successfully implement the recommendations of critical care nutrition guidelines, one potential approach is to identify barriers to providing optimal enteral nutrition (EN) in the intensive care unit (ICU), and then address these barriers systematically. Therefore, the purpose of this study was to develop a questionnaire to assess barriers to enterally feeding critically ill patients and to conduct preliminary validity testing of the new instrument. Methods The content of the questionnaire was guided by a published conceptual framework, literature review, and consultation with experts. The questionnaire was pre-tested on a convenience sample of 32 critical care practitioners, and then field tested with 186 critical care providers working at 5 hospitals in North America. The revised questionnaire was pilot tested at another ICU (n?=?43). Finally, the questionnaire was distributed to a random sample of ICU nurses twice, two weeks apart, to determine test retest reliability (n?=?17). Descriptive statistics, exploratory factor analysis, Cronbach alpha, intraclass correlations (ICC), and kappa coefficients were conducted to assess validity and reliability. Results We developed a questionnaire with 26 potential barriers to delivery of EN asking respondents to rate their importance as barriers in their ICU. Face and content validity of the questionnaire was established through literature review and expert input. The factor analysis indicated a five-factor solution and accounted for 72% of the variance in barriers: guideline recommendations and implementation strategies, delivery of EN to the patient, critical care provider attitudes and behavior, dietitian support, and ICU resources. Overall, the indices of internal reliability for the derived factor subscales and the overall instrument were acceptable (subscale Cronbach alphas range 0.84 – 0.89). However, the test retest reliability was variable and below acceptable thresholds for the majority of items (ICC’s range ?0.13 to 0.70). The within group agreement, an indices reflecting the reliability of aggregating individual responses to the ICU level was also variable (ICC’s range 0.0 to 0.82). Conclusions We developed a questionnaire to identify barriers to enteral feeding in critically ill patients. Additional studies are planned to further revise and evaluate the reliability and validity of the instrument. PMID:24305039

    Being able to accurately determine the response of an electrical system which is excited by a high altitude nuclear electromagnetic pulse (EMP) requires a knowledge of the time history of the incident EMP field strength, as well as its angle of incidence and polarization. A commonly used, unclassified, description of this environment is provided by the ''Bell Laboratory waveform.'' Recent studies have shown, however, that this EMP waveform tends to overestimate the response of an above-ground transmission line by more than an order of magnitude. As a result, other unclassified high altitude EMP environments have been developed. This presentation discusses the development of two alternate unclassified EMP environment descriptions: one arising from a simple radiating dipole moment model, and the other resulting from curve-fitting the calculated fields from a computer code named CHAP. For both of these EMP models, the electric field at two earth observation points are compared. These fields are then coupled to an above-ground line and the resulting open-circuit voltage responses are compared. Using the CHAP EMP environment, a limited parametric study of the peak positive and negative open-circuit voltage is then performed and surface plots of these peak voltages are presented. 8 refs., 21 figs., 1 tab.

  20. Family burden in inherited ichthyosis: creation of a specific questionnaire

    PubMed Central

    2013-01-01

    Background The concept of individual burden, associated with disease, has been introduced recently to determine the “disability” caused by the pathology in the broadest sense of the word (psychological, social, economic, physical). Inherited ichthyosis belong to a large heterogeneous group of Mendelian Disorders of Cornification. Skin symptoms have a major impact on patients’ Quality of Life but little is known about the burden of the disease on the families of patients. Objectives To develop and validate a specific burden questionnaire for the families of patients affected by ichthyosis. Methods Two steps were required. First, the creation of the questionnaire which followed a strict methodological process involving a multidisciplinary team and families. Secondarily, the validation of the questionnaire, including the assessment of its reliability, external validity, reproducibility and sensitivity, was carried out on a population of patients affected by autosomal recessive congenital ichthyosis. A population of parents of patients affected by ichthyosis was enrolled to answer the new questionnaire in association with the Short Form Q12 questionnaire (SF-12) and a clinical severity score was filled for each patient. Results Ninety four families were interviewed to construct the verbatim in order to create the questionnaire and a cognitive debriefing was realized. The concept of burden could be structured around five components: “economic”, “daily life”, “familial and personal relationship”, “work”, and “psychological impact”. As a result, “Family Burden Ichthyosis” (FBI) reproducible questionnaire of 25 items was created. Forty two questionnaires were analyzable for psychometric validation. Reliability (Cronbach’s alpha coefficient?=?0.89), reflected the good homogeneity of the questionnaire. The correlation between mental dimensions of the SF-12 and the FBI questionnaire was statistically significant which confirmed the external validity. The mean FBI score was 71.7?±?18.8 and a significant difference in the FBI score was shown between two groups of severity underlining a good sensitivity of the questionnaire. Conclusions The internal and external validity of the “FBI” questionnaire was confirmed and it is correlated to the severity of ichtyosis. Ichthyoses, and other chronic pathologies, are difficult to assess by clinical or Quality of Life aspects alone as their impact can be multidimensional. “FBI” takes them all into consideration in order to explain every angle of the handicap generated.

    Background: A trial of corticosteroids has been recommended for all patients with chronic obstructive pulmonary disease (COPD), with the subsequent "response" determining the treatment selected. This approach assumes that patients can be reliably divided into responder and non-responder groups. We have assessed whether such a separation is statistically valid, which factors influence the change in forced expiratory volume in 1 second (FEV1) after prednisolone, and whether the prednisolone response predicts 3 year changes in FEV1, health status, or number of exacerbations during placebo or fluticasone propionate treatment. Methods: Oral prednisolone 0.6 mg/kg was given for 14 days to 524 patients with COPD before randomised treatment for 3 years with fluticasone propionate or placebo. Factors relating to change in FEV1 after prednisolone were investigated using multiple regression. The response to prednisolone was entered into separate mixed effects models of decline in FEV1 and health status during the 3 years of the study. Results: The post-bronchodilator FEV1 increased by a mean 60 ml (CI 46 to 74) after prednisolone with a wide unimodal distribution. Current smoking was the factor most strongly associated with the change in FEV1 after prednisolone, with an increase of 35 ml in current smokers and 74 ml in confirmed ex-smokers (p<0.001). There was no relationship between the change in FEV1 after prednisolone and the response to inhaled bronchodilators, baseline FEV1, atopic status, age, or sex. The response to prednisolone, however expressed, was unrelated to the subsequent change in FEV1 over the following 3 years on either placebo or fluticasone propionate. Regression to the mean effects explained much of the apparent prednisolone response. The significant effect of treatment on decline in health status was not predicted by the prednisolone response. Conclusion: Patients with COPD cannot be separated into discrete groups of corticosteroid responders and non-responders. Current smoking reduces the FEV1 response to prednisolone. Prednisolone testing is an unreliable predictor of the benefit from inhaled fluticasone propionate in individual patients. PMID:12885977

    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.

    Combustion instability is a resonance phenomenon that arises due to the coupling between the system acoustics and the unsteady heat release. The constructive feedback between the two processes, which is known to occur as a certain phase relationship between the pressure and the unsteady heat release rate is satisfied, depends on many parameters among which is the acoustic mode, the flame holder characteristics, and the dominant burning pattern. In this paper, the authors construct an analytical model to describe the dynamic response of a laminar premixed flame stabilized on the rim of a tube to velocity oscillation. They consider uniform and nonuniform velocity perturbations superimposed on a pipe flow velocity profile. The model results show that the magnitude of heat release perturbation and its phase with respect to the dynamic perturbation dependent primarily on the flame Strohal number, representing the ratio of the dominant frequency times the tube radius to the laminar burning velocity. In terms of this number, high-frequency perturbations pass through the flame while low frequencies lead to a strong response. The phase with respect to the velocity perturbation behaves in the opposite way. Results of this model are shown to agree with experimental observations and to be useful in determining how the combustion excited model is selected among all the acoustic unstable modes. The model is then used to obtain a time-domain differential equation describing the relationship between the velocity perturbation and the heat release response over the entire frequency range.

    Objective To form a normative set of responses to the GHABP questionnaire from a large regional dataset. Design Participants were asked to rate their hearing disability, handicap, hearing-aid (HA) use, HA benefit, HA satisfaction and residual (aided) disability on a five-point scale for four situations: quiet conversation, television (TV) listening, noisy conversation and group conversation. A subset of participants also estimated the time spent in these situations. Study sample 1574 adults with normal to profound hearing thresholds participated. Results There was a significant relationship between increasing perceived disability and increasing hearing loss as given by the better-ear audiometric average (BEA). Responses for HA measures did not vary greatly with hearing loss: HA use was reported as high, whereas residual disability, HA benefit and satisfaction were all reported on average as moderate. Conclusions The results can be used as a normative dataset with which to evaluate individual responses in the clinic, where the GHABP provides a useful short-form questionnaire to engage the patient. The lack of systematic changes in hearing-aid related responses shows room for improvement in the benefit afforded by amplification. PMID:24484267

    In this paper, a trial to educate electronics for both elementary pupils and junior-high students is reported. A “making your own radio” workshop for elementary kids features a paper-craft resonator made of toilet paper cores and an empty box of tissue papers as well as solder-less main radio circuit. For elder elementary and junior-high pupils, a workshop making a bat detector (an ultra-sonic receiver) is provided to help their summer vacation research. Both workshops are planned to enlarge students wishing to knock the door of electronics. Also, we report questionnaires results for those workshops and follow up research results for bat detector workshop. Those results show that both children and parents long for good experiences on science/electronics materials and these experiences are important for future human resources in scientific fields including analog electronics.

    The Nephrology Quiz and Questionnaire remains an extremely popular session for attendees of the Annual Kidney Week Meeting of the American Society of Nephrology. Once again, in 2014 the conference hall was overflowing with audience members and eager quiz participants. Topics covered by the expert discussants included electrolyte and acid-base disorders, glomerular disease, ESRD/dialysis, and transplantation. Complex cases from each of these categories along with single-best-answer questions were prepared and submitted by the panel of experts. Before the meeting, program directors of United States nephrology training programs and nephrology fellows answered the questions using an Internet-based questionnaire. During the live session, members of the audience tested their knowledge and judgment on a series of case-oriented questions prepared and discussed by the experts. They compared their answers in real time using audience response devices with the answers of the nephrology fellows and training program directors. The correct and incorrect answers were then discussed after the audience responses and the results of the questionnaire were displayed. As always, the audience, lecturers, and moderators enjoyed this educational session. This article recapitulates the acid-base and electrolyte disorders portion of the session and reproduces its educational value for the readers of the Clinical Journal of the American Society of Nephrology.

    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.

    The ability to successfully develop to the highest levels in sport is dependent on a range of variables, not least an individual's ability to cope with the various challenges of development. Psychological Characteristics of Developing Excellence (PCDEs) include both the trait characteristics and the state-deployed skills that have been shown to play a crucial role in the realisation of potential. Psychological characteristics of developing excellence equip aspiring elites with the mental skills, attitudes, and emotions to cope with the challenges of the development pathway, as well as underpinning their capacity to make the most of their innate abilities. The Psychological Characteristics of Developing Excellence Questionnaire (PCDEQ) was designed to assess the possession and deployment of these characteristics. The purpose of this paper was to examine the ability of the Psychological Characteristics of Developing Excellence Questionnaire to effectively discriminate between good and poor developers based on their current possession and deployment of psychological characteristics of developing excellence. Two hundred and eighty-five athletes (n = 192 team athletes; n = 93 individual athletes) completed the Psychological Characteristics of Developing Excellence Questionnaire. Results from the discriminant function analysis suggest that the Psychological Characteristics of Developing Excellence Questionnaire correctly classifies between 67% and 75% of athletes based on their responses. The Psychological Characteristics of Developing Excellence Questionnaire can be used as a formative assessment tool to direct training programmes by identifying weaknesses in psychological characteristics of developing excellence and incorporating specific training to address these weaknesses in advance of developmental challenges.

    Although critical analysis of survey research is limited when reviewers and readers cannot view a study's questionnaire, access to novel questionnaires used in published research has not been systematically examined. The authors identified publications reporting the results of novel questionnaires in three medical journals (JAMA, The New England Journal of Medicine, and The Lancet) in January 2000-May 2003 and searched portable document format (PDF) versions of the studies for the complete questionnaire or a Uniform Resource Locator (URL) providing access to the questionnaire. When the questionnaire was not provided in the publication or a published URL, the authors requested it from the corresponding author in writing up to three times over a 6-week period. Of 93 publications with novel questionnaires, four printed the questionnaire in the article and three provided online access. Corresponding authors failed to provide questionnaires for 37 of 81 (46%) studies. Novel questionnaires used in published research are frequently not available to readers or researchers. Policies that improve access to novel questionnaires will allow better assessment of study results, reduce duplicated efforts, and improve authorship attribution for questionnaire design.

    2010-01-01

    The development of novel immune adjuvants is emerging as a significant area of vaccine delivery based on the continued necessity to amplify immune responses to a wide array of new antigens that are poorly immunogenic. This article specifically focuses on the application of nanoparticles and microparticles as vaccine adjuvants. Many investigators are in agreement that the size of the particles is crucial to their adjuvant activities. However, reports on correlating the size of particle-based adjuvants and the resultant immune responses have been conflicting, with investigators on both sides of the fence with impressive data in support of the effectiveness of particles with small sizes (submicron) over those with larger sizes (micron) and vice versa, while other investigators reported data that showed submicron- and micron-sized particles are effective to the same degree as immune adjuvants. We have generated a list of biological, immunological and, more importantly, vaccine formulation parameters that may have contributed to the inconsistency from different studies and made recommendations on future studies attempting to correlate the size of particulate adjuvants and the immune responses induced. The information gathered could lead to strategies to optimize the performance of nano-microparticles as immune adjuvants. PMID:20822351

    On June 12,2003, the Alameda County Public Health Department and Sandia National Laboratories/CA jointly conducted an exercise that used a Weapons of Mass Destruction-Decision Analysis Center (WMD-DAC) bioterrorism attack simulation to test the effectiveness of the county's emergency response plan. The exercise was driven by an assumed release (in the vicinity of the Berkeley Marina), and subsequent spread, of a small quantity of aerosolized, weapons-grade anthrax spores. The simulation used several key WMD-DAC capabilities, namely: (1) integration with an atmospheric dispersion model to calculate expected dose levels in the affected areas, (2) a individual-tracking capability for both infected and non-infected persons as they made decisions, sought treatment, and received prophylaxis drugs, and (3) a user interface that allows exercise participants to affect the scenario evolution and outcome. The analysis of the county's response plan included documenting and reviewing the decisions made by participants during the exercise. Twenty-six local and regional officials representing the health care system, emergency medical services and law enforcement were involved in responding to the simulated attack. The results of this joint effort include lessons learned both by the Alameda County officials regarding implementation of their bioterrorism response plan and by the Sandia representatives about conducting exercises of this type. These observations are reviewed in this report, and they form a basis for providing a better understanding of group/individual decision processes and for identifying effective communication options among decision makers.

    The dynamic response of a large spar platform was investigated. A 1:55 scale model of the platform was tested at the wave basin of the Center at Texas A and M University. It was subjected to unidirectional monochromatic, bichromatic, and irregular waves in deep water. The prototype spar with a diameter of D = 40.5 m and a draft of h = 198.2 m would be moored to the sea floor in a water depth of 922 meters. Numerical predictions using second-order diffraction/radiation theory are compared in this paper to the experimental results to assess the degree of appropriateness provided by this theory alone. The first- and second-order diffraction forces and radiation coefficients were computed with WAMIT5.1s, a widely-used radiation/diffraction panel program for bodies of arbitrary geometry. The forces and radiation coefficients obtained for a truncated cylinder with the spar`s dimensions were then input into a program that calculates responses using the hydrodynamic equations of motion of a rigid body with three degrees of freedom. The response program interpolates between actual hydrodynamic force values computed by WAMIT so that high resolution spectral outputs can be obtained. Mooring lines were modeled by linear springs although their behavior was nonlinear for large displacements. The numerical and experimental responses for surge and pitch are compared in the form of time histories and spectral densities. The heave motion was not considered because it should be more strongly affected by viscous damping which was not included in the model.

    This paper describes development and validation of the Parental Psychological Flexibility (PPF) Questionnaire, a parent-report measure designed to assess psychological flexibility among parents of pre-adolescents and adolescents (aged 10-18 years). Psychological flexibility within parenting refers to parents' accepting negative thoughts, emotions and urges about one's child and still acting in ways that are consistent with effective parenting. Exploratory factor analysis (n = 178 parents) of a 43-item draft measure, resulted in a 30-item, 3-factor structure. Three subscales were created, consistent with the psychological flexibility literature: acceptance, cognitive defusion and committed action. A second sample of parents (n = 192) was then used to confirm the factor structure and reliability and validity of the PPF. Results supported the 3-factor structure, reduced the number of items to 19 and demonstrated that the PPF subscales have adequate reliability and validity and are thus suitable for researching psychological flexibility among parents of pre-adolescents and adolescents.

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

    2014-01-01

    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

  19. Cognitive interviews guide design of a new CAM patient expectations questionnaire

    PubMed Central

    2014-01-01

    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

  20. Climate Responses to Stratospheric SRM: Results from a Perturbed Physics Ensemble Modeling Experiment

    While many have argued that the potential future deployment of solar radiation management (SRM) technologies hinges upon the uncertainty around the value of climate sensitivity, modeling studies of the climate’s response to SRM forcings have thus far focused on best-guess modeling frameworks which yield climate sensitivity values close to the Coupled Model Intercomparison Project (CMIP) dataset mean. Thus, most SRM modeling experiments to-date say little about the range of climate responses we may observe if SRM were implemented in high- or low- climate sensitivity worlds. The work presented here aims to see how climate responses to SRM under the physics that produce high climate sensitivity may differ from the responses modeled so far using best-guess model parameters. We present preliminary results from a “perturbed physics” ensemble modeling experiment implemented using climateprediction.net (cpdn). Perturbed physics climate modeling experiments simulate past and future climate scenarios using a wide combination of model parameter combinations with the aim of both simulating past climate with some level of accuracy and also projecting future climates that exhibit a wide range of climate sensitivities. Ensemble members were selected using an algorithm for model selection regional surface temperature data from the cpdn simulation output for model years 1961-2005 (in five year averages) to observational data from the HadCRUT3 (land) and HadSST2 (ocean) datasets at the same spatial and temporal resolution. Stratospheric SRM is simulated in the model by specifying stratospheric optical depth. Several scenarios are tested including several designed to stabilize mean global temperature at different levels, two scenarios designed to rapidly cool the climate starting in 2020 and 2035, respectively, and a scenario which makes small, periodic perturbations (in order to glean information about detectability and the feasibility of large-scale SRM testing schemes). All scenarios use anthropogenic emissions scenario RCP 4.5 and are compared to an RCP 4.5/no-SRM control. We will present global and regional results from this ongoing experiment.

    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

    This research reassessed the psychometric properties and predictive validity of the Self-Appraisal Questionnaire (SAQ) in response to published criticism of the authors' earlier work. The current research used a much longer recidivism tracking-period, a different measure of recidivism, a larger sample, and more advanced analytic techniques than the original. Examination of the SAQ's psychometric properties continued to indicate that three of the six recidivism prediction subscales exhibited substandard levels of reliability and four of these subscales were not unidimensional. Yet, in contrast to the author's earlier results, the current analyses found that SAQ total score modestly predicted reconviction. PMID:22297774

    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.

  5. Does amplitude scaling of ground motion records result in biased nonlinear structural drift responses?

    Limitations of the existing earthquake ground motion database lead to scaling of records to obtain seismograms consistent with a ground motion target for structural design and evaluation. In the engineering seismology community, acceptable limits for 'legitimate' scaling vary from one (no scaling allowed) to 10 or more. The concerns expressed by detractors of scaling are mostly based on the knowledge of, for example, differences in ground motion characteristics for different earthquake magnitude-distance (Mw-Rclose) scenarios, and much less on their effects on structures. At the other end of the spectrum, proponents have demonstrated that scaling is not only legitimate but also useful for assessing structural response statistics for Mw-Rclose scenarios. Their studies, however, have not investigated more recent purposes of scaling and have not always drawn conclusions for a wide spectrum of structural vibration periods and strengths. This article investigates whether scaling of records randomly selected from an Mw-Rclose bin (or range) to a target fundamental-mode spectral acceleration (Sa) level introduces bias in the expected nonlinear structural drift response of both single-degree-of-freedom oscillators and one multi-degree-of-freedom building. The bias is quantified relative to unscaled records from the target Mw-Rclose bin that are 'naturally' at the target Sa level. We consider scaling of records from the target Mw-Rclose bin and from other Mw-Rclose bins. The results demonstrate that scaling can indeed introduce a bias that, for the most part, ca be explained by differences between the elastic response spectra of the scaled versus unscaled records.

  6. Principle component analyses of questionnaires measuring individual differences in synaesthetic phenomenology.

    Anderson, Hazel P; Ward, Jamie

    2015-05-01

    Questionnaires have been developed for categorising grapheme-colour synaesthetes into two sub-types based on phenomenology: associators and projectors. The general approach has been to assume a priori the existence of two sub-types on a single dimension (with endpoints as projector and associator) rather than explore, in a data-driven fashion, other possible models. We collected responses from 175 grapheme-colour synaesthetes on two questionnaires, the Illustrated Synaesthetic Experience Questionnaire (Skelton, Ludwig, & Mohr, 2009) and Rouw and Scholte's (2007) Projector-Associator Questionnaire. After Principle Component Analysis both questionnaires were comprised of two factors which coincide with the projector/associator distinction. This suggests that projectors and associators are not opposites of each other, but separate dimensions of experience (e.g. some synaesthetes claim to be both, others claim to be neither). The revised questionnaires provide a useful tool for researchers and insights into the phenomenology of synaesthesia. PMID:25703387

    Research on the role of acceptance in adjustment to persisting pain has been facilitated by the development of the Chronic Pain Acceptance Questionnaire (CPAQ). However, the CPAQ has not yet been validated amongst Iranian patients with chronic pain. To examine the psychometric properties of the Persian version of the CPAQ (P-CPAQ), 245 Persian-speaking chronic pain patients completed a battery of questionnaires, including: the P-CPAQ, a Pain Self-Efficacy Questionnaire, a slightly modified Roland and Morris Disability Questionnaire, the Catastrophizing Scale of the Coping Strategies Questionnaire, the Depression and Anxiety Scales of the Depression Anxiety And Stress Scale-21 and the Pain-Related Interference and Pain Intensity Scales of the Multidimensional Pain Inventory. Furthermore, to evaluate the reliability of the P-CPAQ, the measure was completed by 24 chronic pain patients, on two occasions that are 2 weeks apart. The results of the principal component analysis and confirmatory factor analysis yielded a two-factor solution. Furthermore, the reliability and construct validity of the P-CPAQ were confirmed. In general, consistent with studies in other countries, the results of the present study indicate that pain acceptance plays an important role in adjustment to chronic pain regardless of cultural and language differences between countries.

    Background Identification and treatment of unrecognised asthmatics in the community is important for improving the health of the individual and minimising cost and quality of life burden. It is not practical to offer clinical diagnostic assessment to whole communities, and a simple tool such as a questionnaire is required to identify a smaller target group. Conventional questionnaire screening methods which separate individuals into positive and negative categories have resulted in large numbers of individuals requiring clinical assessment. This study has therefore developed and tested a weighted scoring system that prioritises those most urgently in need, based on their questionnaire responses. Methods A stratified random sample of adult respondents to a general practice postal questionnaire survey were categorised 'asthmatic' or 'non-asthmatic' according to three expert physicians' opinions. Based on this categorisation, logistic regression was used to derive weights reflecting the relative importance of each question in predicting asthma, allowing calculation of weighted scores reflecting likelihood of asthma. Respondents scoring higher than a chosen threshold would be offered diagnostic examination. Results Age and presence of wheeze were most influential (weight 3) and overall weighted scores ranged from -1 to 13. Positive predictive values (PPV) were estimated. For example, setting the threshold score at nine gave an estimated PPV for asthma diagnosis of 93.5%, a threshold score of seven corresponded to PPV 78.8%. PPV estimates were supported by examining 145 individuals from a new survey. Conclusion Weighted scoring of questionnaire responses provides a method for evaluating the priority level of an individual 'at a glance', minimising the resource wastage of examining false positives.

    OBJECTIVES: The questionnaire 16 (Q16) is commonly used to study prevalences of neurotoxic symptoms among workers exposed to organic solvents. It has also been recommended that exposed workers reporting more than six symptoms should be referred for further examination of possible chronic toxic encephalopathy. It would be useful to know whether symptoms reported in the questionnaire also reflect impairment of similar functions measured with objective or semiobjective methods in a formerly highly exposed group. METHODS: 135 painters and 71 carpenters answered the Q16, were interviewed about symptoms compatible with an organic brain damage, and took a battery of psychometric tests. A subsample of 52 painters and 45 carpenters were interviewed for psychiatric diagnosis according to Diagnostic and Statistical Manual for Mental Disorders, 3rd version (DSM III) and their vibration thresholds in hands and feet were measured. The entire group was followed up in the register of diagnoses at early retirement 1971-93. The lifetime exposure to organic solvents was assessed. Current exposure to organic solvents was found to be low or none. RESULTS: The prevalence of people with more than six symptoms in the Q16 rose with increasing cumulative exposure to solvents. The sensitivity of the questionnaire (more than six symptoms) to detect people who were assessed to exhibit symptoms compatible with an organic brain damage was only 38%. One of seven people who had retired early with a diagnosis compatible with a chronic toxic encephalopathy, and two of five people with a psychiatric diagnosis compatible with this condition, had more than six symptoms in the Q16. The agreement between Q16 replies and psychometric test results, as well as other examinations, was low. CONCLUSIONS: The notable exposure-response relation indicates that the questionnaire is useful for comparison of groups with different exposures to organic solvents. There was low agreement between the number of symptoms on the questionnaire and the assessment of symptoms compatible with organic brain damage, as well as psychiatric, or early retirement diagnoses compatible with chronic toxic encephalopathy. The questionnaire does not seem useful for screening of patients with chronic toxic encephalopathy in groups without ongoing exposure to organic solvents. PMID:9196457

    Introduction: Relapse is the most common smoking cessation outcome. Accurate prediction of relapse likelihood could be an important clinical tool used to influence treatment selection or duration. The aim of this research was to develop a brief clinical relapse proneness questionnaire to be used with smokers interested in quitting in a clinical setting where time is at a premium. Methods: Diverse items assessing constructs shown in previous research to be related to relapse risk, such as nicotine dependence and self-efficacy, were evaluated to determine their independent contributions to relapse prediction. In an exploratory dataset, candidate items were assessed among smokers motivated to quit smoking who enrolled in one of three randomized controlled smoking cessation trials. A cross-validation dataset was used to compare the relative predictive power of the new instrument against the Fagerström Test for Nicotine Dependence (FTND) at 1-week, 8-week, and 6-month postquit assessments. Results: We selected seven items with relatively nonoverlapping content for the Wisconsin Predicting Patient's Relapse (WI-PREPARE) measure, a brief, seven-item questionnaire that taps physical dependence, environmental factors, and individual difference characteristics. Cross-validation analyses suggested that the WI-PREPARE demonstrated a stronger prediction of relapse at 1-week and 8-week postquit assessments than the FTND and comparable prediction to the FTND at a 6-month postquit assessment. Discussion: The WI-PREPARE is easy to score, suggests the nature of a patient's relapse risk, and predicts short- and medium-term relapse better than the FTND. PMID:19372573

    The suprachiasmatic nucleus (SCN) drives circadian rhythms in behavioral and physiological variables, including the inflammatory response. Shift work is known to disturb circadian rhythms and is associated with increased susceptibility to develop disease. In rodents, circadian disruption due to shifted light schedules (jet lag) induced increased innate immune responses. To gain more insight into the influence of circadian disruption on the immune response, we characterized the inflammatory response in a model of rodent shift work and demonstrated that circadian disruption affected the inflammatory response to lipopolysaccharide (LPS) both in vivo and in vitro. Since food consumption is a main disturbing element in the shift work schedule, we also evaluated the inflammatory response to LPS in a group of rats that had no access to food during their working hours. Our results demonstrated that the shift work schedule decreased basal TNF-? levels in the liver but not in the circulation. Despite this, we observed that shift work induced increased cytokine response after LPS stimulation in comparison to control rats. Also, Kupffer cells (liver macrophages) isolated from shift work rats produced more TNF-? in response to in vitro LPS stimulation, suggesting important effects of circadian desynchronization on the functionality of this cell type. Importantly, the effects of shift work on the inflammatory response to LPS were prevented when food was not available during the working schedule. Together, these results show that dissociating behavior and food intake from the synchronizing drive of the SCN severely disturbs the immune response. PMID:26017928

    Purpose There are no specific tools for measurement of the severity of chronic cough in Korea. We developed a Korean version of the Leicester Cough Questionnaire (LCQ) and tested its scaling and clinical properties. Methods The LCQ was adapted for Korean conditions following a forward-backward translation procedure. All patients referred to chronic cough clinics at 5 university hospitals between May 2011 and October 2013 completed 2 questionnaires, the LCQ and the Short-Form 36 (SF-36), upon presentation and completed the LCQ and the Global Rating of Change (GRC) upon follow-up visits after 2 or 4 weeks. Concurrent validation, internal consistency, repeatability, and responsiveness were determined. Results For the concurrent validation, the correlation coefficients (n=202 patients) between the LCQ and SF-36 varied between 0.42 and 0.58. The internal consistency of the LCQ (n=207) was high for each of the domains with a Cronbach's alpha coefficient of 0.82-0.94. The repeatability of the LCQ in patients with no change in cough (n=23) was high, with intra-class correlation coefficients of 0.66-0.81. Patients who reported an improvement in cough (n=30) on follow-up visits demonstrated significant improvement in each of the domains of the LCQ. Conclusions The Korean version of the LCQ is a valid and reliable questionnaire for measurement of the severity of cough in patients with chronic cough. PMID:25749761

    Soil microbial response after fire is controlled by numerous variables which conclude with a mosaic of results depending on organic carbon alterations or pH fire-induced changes. This fact has complicated the studies focused on post-fire microbial response, compiling high variability of opposite result in the bibliography. Soil laboratory heating cannot emulate a real wildfire effect on soil but lead us the possibility to control several variables and it is a valid tool to clarify the relative weight of different factors controlling microbial response after soil heating. In this preliminary study different heated treatments were applied to unaltered forest soil samples, obtaining 4 different heating treatments to simulate a range of fire intensities: unaltered-control (UH), and soil heated at 300, 450 and 500 °C. In order to isolate possible nutrient availability or pH heating-induced changes, different culture media were prepared using soil:water extract from each heating treatments and adding different supplements to obtain the total of 11 different culture media: unheated soil without supplements (UH-N-), unheated soil with nutrient supplement (UH-N+), soil heated at 300 °C without supplements (300-N-), soil heated at 300 °C with nutrient supplement (300-N+), soil heated at 300 °C with nutrient supplement and pH-buffered (300-N+pH); soil heated at 450 °C without supplements (450-N-), soil heated at 450 °C with nutrient supplement (450-N+), soil heated at 450 °C with nutrient supplement and pH-buffered (450-N+); soil heated at 500 °C without supplements (500-N-), soil heated at 500 °C with nutrient supplement (500-N+), soil heated at 500 °C with nutrient supplement and pH-buffered (500-N+). Each media was inoculated with different dilutions of a microbial suspension from the original unaltered soil, and the abundance of viable and cultivable microorganisms were measured by plate count method. In addition, the analysis of heating-induced soil organic matter alteration by mean of pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) technique was applied to soil samples and soil:water extract in order to obtain a deeper understanding of soil organic matter-microorganisms interaction after fire. Heating effect on soil:water extract media was evident since the number CFU in those media prepared by mean of heated soil was lower than those counted in media prepared with unaltered soil and inoculated with the same dilution. Nutrient addition appear to promote microbial proliferation in unaltered and 300 °C treatments, while nutrient and pH compensation appear to attenuate heating effect in samples heated at 300 and 450 °C. While, media prepared with soil:water extract form soil heated at 500°C showed similar CFU abundance in all supplement treatments. Soil organic matter analyses evidences difference in the pyrogram obtained from each heating treatment sample, with a marked diminution of peaks with increased temperature. This preliminary study shows us the importance of soil organic matter fire-induced alterations in soil microbial response after soil heating process beyond the C content diminution or changes in C availability.

    C use efficiency (CUE) is one of the least understood aspects of soil C cycling, has a very large effect on soil respiration and C sequestration, and decreases with elevated temperature. CUE is directly related to substrate partitioning over energy production and biosynthesis. The production of energy and metabolic precursors occurs in well-known processes such as glycolysis and Krebs cycle. We have developed a new stable isotope approach using position-specific 13C-labeled metabolic tracers to measure these fundamental metabolic processes in intact soil communities (1). We use this new approach, combined with models of soil metabolic flux patterns, to analyze the response of microbial energy production, biosynthesis, and CUE to temperature. The method consists of adding small but precise amounts of position-specific 13C -labeled metabolic tracers to parallel soil incubations, in this case 1-13C and 2,3-13C pyruvate and 1-13C and U-13C glucose. The measurement of CO2 released from the labeled tracers is used to calculate the C flux rates through various metabolic pathways. A simplified metabolic model consisting of 23 reactions is iteratively solved using results of the metabolic tracer experiments and information on microbial precursor demand under different temperatures. This new method enables direct study of fundamental aspects of microbial energy production, C use efficiency, and soil organic matter formation in response to temperature.

    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.

    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

    Using of EMR in health services and organizations is steadily increasing for quality improvement, cost effectiveness and performance development. However, no validated national and international instruments (scale, questionnaire, index, and inventory) have assessed the effectiveness, satisfaction, health care savings, patient safety and cost minimization of electronic medical and health systems from the viewpoint and perceptions of nurses in Turkish health services. The perceptions of health care professionals especially physicians and nurses can contribute important information that may predict their acceptance of EMR and desired mode of use for EMR, evaluation performance of EMR thus guiding EMR implementation in hospitals. This article is a report of validation of the instrument to measure nurses' views on the use, quality and user satisfaction with EMR in Turkish health system. Items in the questionnaire were designed and obtained following O.G. Otieno, H. Toyama, M. Asonuma, M. Kanai-Pak, K. Naitoh's questionnaire about Use, Quality and User Satisfaction with EMR systems. Reliability and validity were examined and investigated in terms of responses from 487 nurses from one education hospital in Ankara, Turkey. This study was planned and conducted at a university hospital. The validation process was based on construct validity in this study. The response rate was 74.92%. Cronbach's alphas of three factors (use, quality and satisfaction of EMR) ranged from 0.78 to 0.94. Goodness-of-fit indices from the confirmatory factor analysis showed a reasonable model fit. Results of confirmatory factor analysis showed that ?2 statistic indicated significant result (p?results in health systems in the different countries. Also further validation and reliability studies could be planned on physicians and other health professionals. PMID:25957164

    We applied item response theory based person-fit analysis (PFA) to data of the Outcome Questionnaire-45 (OQ-45) to investigate the prevalence and causes of aberrant responding in a sample of Dutch clinical outpatients. The [Formula: see text] person-fit statistic was used to detect misfitting item-score patterns and the standardized residual statistic for identifying the source of the misfit in the item-score patterns identified as misfitting. Logistic regression analysis was used to predict person misfit from clinical diagnosis, OQ-45 total score, and Global Assessment of Functioning code. The [Formula: see text] statistic classified 12.6% of the item-score patterns as misfitting. Person misfit was positively related to the severity of psychological distress. Furthermore, patients with psychotic disorders, somatoform disorders, or substance-related disorders more likely showed misfit than the baseline group of patients with mood and anxiety disorders. The results suggest that general outcome measures such as the OQ-45 are not equally appropriate for patients with different disorders. Our study emphasizes the importance of person-misfit detection in clinical practice. PMID:25520211

  20. Developing the draft descriptive system for the child amblyopia treatment questionnaire (CAT-Qol): a mixed methods study

    PubMed Central

    2013-01-01

    Background Amblyopia is a visual condition that occurs in childhood. Screening programmes exist within the United Kingdom (UK) to detect amblyopia, and once detected treatment is given. Existing patient reported outcome (PRO) measures for amblyopia do not meet current recommendations for the methods adopted during their development, or the way in which the instruments are administered. The overall aim of this study was to produce a self-complete PRO instrument for amblyopia for children aged 4–7 years that uses children’s responses in the development phase. The study comprised a number of stages. This paper reports on the refinement of the descriptive system for the draft instrument (the Child Amblyopia Treatment Questionnaire, CAT-QoL) using qualitative and quantitative methods. Methods The study consisted of three components. Children were asked to read, and complete the draft questionnaire as independently as possible. They were then asked about the questionnaire, and its format, in a cognitive debriefing exercise. Observations were made as to the child’s ability to read the questionnaire, particular attention was made as to which individual words participants struggled to read. Children were also asked their opinion on the design layout of the questionnaire. Finally, some children were asked to complete a ranking task to help determine the order of the levels of the items as judged by the children. Mid-rank scoring and statistical level of agreement were calculated for the ranking exercise. Results Thirty-two (n=32) participants completed a draft questionnaire; each of these underwent a cognitive de-briefing interview. Twenty-two (n=22) children completed the ranking exercise. Ten children did not understand the concept of ranking. The results of the qualitative phase (cognitive de-briefing interview) were used to modify the wording of items and layout of the instrument. Results of the ranking exercise were used to inform the order of the response levels for the items. Conclusion Responses of young children can be used in the development of PRO instruments. They are able to help inform the content, wording, and format of an instrument, ensuring good content and face validity. The results have been used to further refine the CAT-QoL, however further research is required to assess the psychometric properties of the instrument. PMID:24148800

    Learning needs assessment is an important stage of every educational process that aims to inform changes in practice and policy for continuing professional development. Professional competencies have been widely used as a basis for the development of learning needs assessment. The Canadian Community Health Nursing Standards of Practices (CCHN Standards) were released in 2003. However, it is not known whether community health nurses (CHNs) have the educational background to enable them to meet these standards. This article reports on the development of a learning needs assessment questionnaire for CHNs. Exploratory and confirmatory factor analyses were conducted to examine the consistency of factors underpinning the CCHN Standards. Also, validity and reliability of the questionnaire were evaluated using appropriate techniques. This process resulted in a valid and reliable CHN learning needs assessment questionnaire to measure learning needs of large groups of practitioners, where other forms of measurement cannot be feasibly conducted.

  2. Does training-induced orthostatic hypotension result from reduced carotid baroreflex responsiveness?

    1994-01-01

    As manned space travel has steadily increased in duration and sophistication, the answer to a simple, relevant question remains elusive. Does endurance exercise training - high intensity rhythmic activity, performed regularly for extended periods of time - alter the disposition to, or severity of, postflight orthostatic hypotension? Research results continue to provide different views; however, data are difficult to compare because of the following factors that vary between investigations: the type of orthostatic stress imposed (+Gz, lower body negative pressure (LBNP), head-up tilt); pretest perturbations used (exercise, heat exposure, head-down tilting, bed rest, water immersion, hypohydration, pharmacologically-induced diuresis); the length of the training program used in longitudinal investigations (days versus weeks versus months); the criteria used to define fitness; and the criteria used to define orthostatic tolerance. Generally, research results indicate that individuals engaged in aerobic exercise activities for a period of years have been reported to have reduced orthostatic tolerance compared to untrained control subjects, while the results of shorter term longitudinal studies remain equivocal. Such conclusions suggest that chronic athletic training programs reduce orthostatic tolerance, whereas relatively brief (days to weeks) training programs do not affect orthostatic tolerance to any significant degree (increase or decrease). A primary objective was established to identify the alterations in blood pressure control that contribute to training-induced orthostatic hypotension (TIOH). Although any aspect of blood pressure regulation is suspect, current research has been focused on the baroreceptor system. Reductions in carotid baroreflex responsiveness have been documented in exercise-trained rabbits, reportedly due to an inhibitory influence from cardiac afferent, presumably vagal, nerve fibers that is abolished with intrapericardiac denervation. The purpose of this investigation was to attempt to determine if similar relationships existed in men with varied levels of fitness, using maximal aerobic power, VO2 max, as the marker of fitness.

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

    PubMed Central

    2014-01-01

    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

    This study assessed the validity and test-retest reliability of a medical and occupational history questionnaire for workers performing welding in the shipyard industry. This self-report questionnaire was developed for an epidemiologic study of the risk of parkinsonism in welders. Validity participants recruited from three similar shipyards were asked to give consent for access to personnel files and complete the questionnaire. Responses on the questionnaire were compared with information extracted from personnel records. Reliability participants were recruited from the same shipyards and were asked to complete the questionnaire at two different times approximately 4 weeks apart. Percent agreement, kappa, intraclass correlation coefficient (ICC), and sensitivity and specificity were used as measures of validity and/or reliability. Personnel files were obtained for 101 of 143 participants (70%) in the validity study, and 56 of the 95 (58.9%) participants in the reliability study completed the retest of the questionnaire. Validity scores for items extracted from personnel files were high. Percent agreement for employment dates and job titles ranged from 83–100%, while ICC for start and stop dates ranged from 0.93–0.99. Sensitivity and specificity for current job title ranged from 0.5–1.0. Reliability scores for demographic, medical and health behavior items were mainly moderate or high, but ranged from 0.19 to 1.0. Most recent job/title items such as title, types of welding performed, and material used showed substantial to perfect agreement. Certain determinants of exposure such as days and hours per week exposed to welding fumes demonstrated mainly moderate agreement (? = 0.42–0.47, percent agreement 63–77%); however, mean days and hours reported did not differ between test and retest. The results of this study suggest that participants’ self-report for job title and dates employed are valid compared with employer records. While kappa scores were low for some medical conditions and for caffeine consumption, high kappa scores for job title, dates worked, types of welding, and materials welded suggest participants generated reproducible answers important for occupational exposure assessment.

    Custom software to automatically administer questionnaires on computer screens was installed on computers in four open-plan offices. Five questions related to thermal comfort were presented twice per day for three months. Results indicate that this new method of subjective data collection was successful and efficient: the participants had few complaints about the method of questionnaire delivery, and a substantial literature review demonstrates that the results are comparable with results from other field studies of thermal comfort conducted using different methods. Participants responded to the questionnaire 29% of the occasions on which it could have been presented and took an average of 45 seconds to answer the five questions. Overall, the number of thermal sensation votes indicating thermal acceptability were as predicted by the ANSI/ASHRAE Standard and by the comfort theory on which this standard was based. However, the results indicate a greater sensitivity to temperatures away from the neutral temperature than theory predicts. Only 11% of the variance in thermal sensation vote was explained by indoor air temperature. Approximately 15% of the people modified their clothing in the hour prior to the appearance of the questionnaire, suggesting that clothing modification may be an important mechanism for achieving thermal comfort.

    Objectives To determine the current status of History of Medicine student selected components (SSC) at UK medical schools. This includes the frequency, methods of delivery, assessment, and evaluation of such courses. Design An 18-item questionnaire was created, piloted, and then sent electronically in January 2010 to participants pertaining to their History of Medicine SSC provision as of 1 January 2010. Initial non-responders were re-sent the questionnaire in February 2010. Setting All UK medical schools. Participants The History of Medicine SSC lead or overall SSC lead at each UK medical school were contacted to ascertain their History of Medicine SSC provision. Main outcome measures Percentages of History of Medicine SSCs for each objective characteristic were obtained as well as general descriptive data. Results Fifteen of the 32 medical schools in the UK offer a History of Medicine SSC. Eleven medical schools (offering a total of 12 SSCs) completed the questionnaire (response rate 73.3%). Eight different teaching methods are used within the SSCs. Medical professionals most frequently deliver the teaching, which most frequently covers the 20th and 21st centuries. Four assessment methods are used among the SSCs, the most common being a group presentation. Questionnaires are the most frequent method of evaluation. There are several factors limiting the provision of some current SSCs, most commonly a lack of staff, teaching facilities, and available time within the curriculum. Conclusion History of Medicine is being delivered more frequently in UK medical schools than when previously researched 40 years ago. However, the subject is still offered in a minority of the medical schools. This study offers useful information to consider for the development of current and potential new History of Medicine SSCs.

    2013-01-01

    Background While there are numerous instruments for capturing the symptoms of fibromyalgia syndrome (FMS) patients, there is a lack of questionnaires capable of measuring in detail FMS patients’ participation and social functioning. It was our aim to develop and methodologically test a new patient questionnaire specific to FMS measuring these concepts (the “Fibromyalgia Participation Questionnaire” FPQ). Methods We first conducted a qualitative prestudy (focus groups, N?=?38) to identify which impairments FMS patients experience in daily life because of their illness. To analyze the data we developed a coding system that contained 10 supercategories and a total of 105 subcategories. Items for the FPQ were developed from the subcategories. The psychometric analysis was done on a sample of N?=?256 FMS patients undergoing inpatient rehabilitation in Germany. Results The final version of the FPQ contained 27 items and three scales (participation in social life FPQ-S, 11 items; participation in daily life FPQ-D, 11 items, participation in work-life FPQ-W 5 items). The FPQ displays good distribution properties, all the scales are unidimensional, and the scales fit to the Rasch model. Cronbach’s Alpha range from 0.85 to 0.94. We noted indications of construct validity in that the FPQ correlates as expected with the Fibromyalgia Impact Questionnaire (physical scale), Pain Disability Index and scales from the PROMIS® item banks for satisfaction with participation. The FPQ scales generally reveal greater responsiveness than other instruments. By linking FPQ items to the categories of the International Classification of Functioning, Disability and Health (ICF) we demonstrate content validity. Conclusions The FPQ captures participation and social functioning in FMS patients. As its psychometric properties are good, it can be recommended for use in evaluation studies and clinical trials.

    Horneck, G.; Eschweiler, U.; Reitz, G.; Wehner, J.; Willimek, R.; Strauch, K.

    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.

    2015-04-01

    During the time range August 2003 - August 2010, we find for 35 disturbances from interplanetary coronal mass ejections (ICMEs) a clear density enhancement in the thermosphere (derived from GRACE and CHAMP accelerometer measurements) by more than 150 percent compared to the pre-event level. For this sample of ICME-thermosphere events, we extract geomagnetic parameters and from the ICME, separately for the sheath and magnetic cloud component, characteristic parameters such as the impact speed, magnetic field orientation as well as strength and disturbance duration. We present a statistical analysis of various ICME parameters and their relation to geomagnetic (Dst, AE, ap, Kp, ...) as well as thermospheric response. We show, among high correlations between geomagnetic and thermospheric quantities, that the strength of the Bz component of the ICME gives the strongest relation to the neutral density enhancement. For most of the events, the strongest negative Bz component is found in the magnetic cloud of the disturbance. Furthermore, the results indicate a shock related intensification of geomagnetic storms and neutral density enhancement due to a larger Bz caused by shock compression.

    Background Early identification of permanent hearing impairment in children enables appropriate intervention which reduces adverse developmental outcomes. The UK Government has introduced a universal hearing screening programme for neonates. All involved health professionals, including those in Primary Care, need to be aware of the service to enable them to offer appropriate support to their patients. A programme of information dissemination within Primary Care was therefore undertaken. The aim of the current study was to determine the extent to which the information had reached General Practitioners (GPs), the GPs' preferred mode of dissemination and the sources from which GPs accessed information Methods Postal questionnaire survey of a randomised sample of 1000 GPs in the Phase I pilot sites of the Neonatal Hearing Screening Programme (NHSP). Results Responses were received from 54.2% of the sample. Just under 50% of those responding had received information, 62.2% of respondents said they would like to receive more information and the preferred methods of dissemination were the written word and web-sites to allow access when needed. Few GPs perceive themselves to have a core role in the delivery of the NHSP and thence a need for knowledge in the subject. Many are keen to delegate detail to a third party, usually the health visitor, who has traditionally had responsibility for hearing screening. Conclusions Dissemination efforts for service developments of relevance to GPs should concentrate on advertising a website address via brief but memorable posted literature and/or articles in relevant journals and magazines. The website should be GP-friendly, and have a dedicated area for GPs including information of specific relevance and downloadable information sheets. PMID:15571626

  18. A mail survey of health care professionals: an analysis of the response

    Mail questionnaires provide a cost effective alternative for the survey of geographically dispersed populations. However, mail questionnaires are also characterized by low response rates, particularly for medical and other professionals. As a result of the potential systematic differences between respondents and nonrespondents, the external validity of the results are jeopardized. A number of techniques, such as follow-ups, have been developed in order to improve the response rates while at the same time retaining the cost advantage of the mail questionnaire. The present article is a discussion of a national survey of chiropractors. Two follow-ups, a postcard reminder, and a second questionnaire were utilized in the survey. An overall response rate of slightly less than sixty-nine (68.78) percent was achieved. These results indicate that satisfactory and realistic response rates can be achieved with health care professionals who are often viewed as being resistant to surveys.

    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. .

    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

  11. Global and Regional Climate Responses Solar Radiation Management: Results from a climateprediction.net Geoengineering Experiment

    NASA Astrophysics Data System (ADS)

    Ricke, Katharine; Allen, Myles; Ingram, William; Keith, David; Granger Morgan, M.

    2010-05-01

    To date modeling studies suggest that, while significant hydrological anomalies could result from the artificial addition of reflecting aerosols in the stratosphere for the purpose of solar radiation management (SRM), even at the regional level such a geoengineered world would bear a much closer resemblance to a low CO2 world, than to an unmodified high CO2 world. These previous modeling studies have generally compared one or two SRM forcing scenarios to various business-as-usual controls. However, such approaches cannot provide much information about regional sensitivities to the levels of SRM that might realistically result. Should engaging in SRM every be seriously contemplated, such regional analysis of a range of realistic scenarios will be an essential input to any process of geopolitical decision-making. Here we present the results from a large-ensemble experiment that used the HadCM3L GCM, implemented through climateprediction.net. The analysis examines 135 globally-uniform stratospheric optical depth modification scenarios designed to stabilize global temperatures under SRES A1B. Scenarios were tested using ten-member subensembles which made small perturbations to initial conditions. All simulations use identical standard settings of model physics parameters and are initiated from historically-forced runs from 1920-2005. A total of 7,331 simulations of the years 2000-2080 were performed for this experiment using computing resources donated by the general public. Our analysis of regional temperature and precipitation anomalies, normalized to account for variability, shows that SRM compensations for anthropogenic greenhouse gas forcing do generally return regional climates closer to their baseline climate states than the no-geoengineering, business-as-usual scenarios. However, we find that the magnitudes and sensitivities of regional responses to this type of activity, as modeled in HadCM3L, are highly variable. As the amount of SRM increases to compensate for rising greenhouse gas concentrations in the atmosphere, regions, such as Eastern China and India, migrate away from their baseline climate states in different ways, illustrating the impossibility of simultaneous stabilization of regional climates. A number of policy-relevant questions about SRM activities have not yet been addressed in the literature. These include whether regional climate factors become more or less variable under SRM as compared to no-geoengineering and how long after deployment of geoengineering forcings it may be before one can determine the global and regional effects with some confidence. We present new analyses in which we exploit our large ensemble to explore several such questions.

  12. A brief cannabis-associated problems questionnaire with less potential for bias.

    PubMed

    Lavender, Jason M; Looby, Alison; Earleywine, Mitch

    2008-08-01

    Existing measures of problems associated with cannabis use may contain gender-biased items. The Cannabis-Associated Problems Questionnaire (CAPQ), a measure of occupational, social, and psychological problems related to cannabis use, contains items that men and women may endorse differentially. Gender discrepancies in CAPQ scores may indicate true differences in overall problem severity but could also signify the presence of biased items. Additionally, a short form could improve the measure's utility. Examination of responses from a large internet sample of current cannabis users revealed five items that functioned differentially for men and women, suggesting a potential for bias. Omitting these items resulted in a shorter scale with nearly identical psychometric properties. Correlations with cannabis use indices were comparable to those of the full scale, and the effect size for the difference between men's and women's responses did not change significantly. Thus, a short form of the CAPQ could benefit cannabis research. PMID:18521820

    The objective of the present study was longitudinal evaluation of the volumetric tumor response and functional results after Gamma Knife radiosurgery of vestibular schwannomas, performed according to the modern standards of treatment. From October 2003 to September 2007, 133 consecutive patients with vestibular schwannomas were treated according to the concept of robotic Gamma Knife microradiosurgery, which is based on precise irradiation of the lesion, sparing adjacent structures, and delivery of the high radiation energy to the target. Multiple small-sized isocenters located within the border of the neoplasm were applied. The mean marginal dose was 11.5 Gy (range, 11-12 Gy). In total, 126 cases with a minimum posttreatment follow-up of 2 years (range, 2-7 years; median, 4 years) were analyzed. Temporary enlargement was noted in 25% of tumors at 6 months after radiosurgery. At 3 years of follow-up, tumor shrinkage, stabilization, and increase in volume were marked in 73%, 23%, and 4% of cases, respectively. All progressing lesions spontaneously stabilized later on and did not require additional management. In 3% of patients, transitory impairment of the facial nerve function was marked; however, neither its permanent dysfunction nor trigeminal neuropathy attributed to radiosurgery was noted. Impairment of hearing compared to its pretreatment level was revealed in 4%, 12%, 13%, and 16% of patients at 6 months, 1 year, 2 years, and 3 years after radiosurgery, respectively, and this trend was statistically significant (P?=?0.0042). Overall, 77% of patients with serviceable hearing before treatment preserved it 3 years thereafter. In conclusion, modern Gamma Knife radiosurgery provides effective and safe management of vestibular schwannomas. Nevertheless, possible temporary tumor enlargement, delay of its growth arrest, transient dysfunction of the cranial nerves, and gradual deterioration of hearing after irradiation should be always taken into consideration.

    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.

    2014-01-01

    Background and Objective Celiac disease (CD) is a common chronic autoimmune disorder. Both the manifestations of the disease and the burden of the compulsory life-long gluten-free diet (GFD) have been shown to be associated with impairment of health-related quality of life. The objectives of this study were to provide a cross-cultural adaptation of the specific quality of life “Celiac Disease Questionnaire” (CDQ) and to analyze its psychometric properties. Materials and Methods A cross-cultural French adaptation of the CDQ (F-CDQ) was obtained according to the revised international guidelines. The questionnaire was administered at baseline to 211 patients with biopsy proven CD followed-up in a single tertiary referral centre. The questionnaire was also administered after 7 days and 6 months. Reliability (intraclass correlation coefficients (ICC), Cronbach's alpha and Bland and Altman graphical analysis), validity (factorial structure and Rasch analysis, convergent validity), and responsiveness (effect size) of the F-CDQ were studied. Results The reliability of the F-CDQ was excellent with ICC and Cronbach's alpha coefficients being between 0.79 and 0.94 for the four subscales and the total score. The factorial structure and the Rasch analysis showed that the four dimensions of the original instrument were retained. Correlations with external measures (a generic measure of quality of life, an anxiety and depression instrument, a self-assessed disease severity, and clinical manifestations) were all in the expected direction confirming the validity of the instrument. Responsiveness was studied and effect sizes ?0.20 were demonstrated for most of the subscales for patients who reported improvement or deterioration after 6 months. Conclusion The F-CDQ retains the psychometric properties of the original instrument and should be useful in cross-national surveys and to assess outcome in clinical trials involving patients with CD.

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

    PubMed Central

    2013-01-01

    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.

    The Obsessive Beliefs Questionnaire-44 (OBQ-44), a self-report measure, was developed by the Obsessive Compulsive Cognitions Working Group (OCCWG) to assess beliefs considered relevant in the etiology and maintenance of obsessions and compulsions. The purpose of this study was to evaluate the psychometric properties of the Persian language version of the Obsessive Beliefs Questionnaire (POBQ-44). A sample of 222 medical students from an Iranian university was used to assess the reliability and validity of the POBQ-44. The results indicated five factors: 1) general, 2) perfectionism, certainty, 3) responsibility and threat estimation, 4) importance and control of thoughts, 5) complete performance. Each of these factors was found to have adequate test-retest and internal consistency reliability. Each of the factors was associated with O-C symptoms. In addition, adequate convergent validity was found with a measure of obsessive compulsive symptoms, and discriminate validity was found with measures of depression and anxiety. PMID:24658991

  3. Seismic Response of a Sedimentary Basin: Preliminary Results from Strong Motion Downhole Array in Taipei Basin

    NASA Astrophysics Data System (ADS)

    Young, B.; Chen, K.; Chiu, J.

    2013-12-01

    The Strong Motion Downhole Array (SMDA) is an array of 32 triggered strong motion broadband seismometers located at eight sites in Taipei Basin. Each site features three to five co-located three-component accelerometers--one at the surface and an additional two to four each down independent boreholes. Located in the center of Taipei Basin is Taipei City and the Taipei metropolitan area, the capital of Taiwan and home to more than 7 million residents. Taipei Basin is in a major seismic hazard area and is prone to frequent large earthquakes producing strong ground motion. This unique three-dimension seismic array presents new frontiers for seismic research in Taiwan and, along with it, new challenges. Frequency-dependent and site-specific amplification of seismic waves from depth to surface has been observed: preliminary results indicate that the top few tens of meters of sediment--not the entire thickness--are responsible for significant frequency-dependent amplification; amplitudes of seismic waves at the surface may be as much as seven times that at depth. Dominant amplification frequencies are interpreted as quarter-wavelength constructive interference between the surface and major interfaces in the sediments. Using surface stations with known orientation as a reference, borehole seismometer orientations in these data--which are unknown, and some of which vary considerably from event to event--have been determined using several methods. After low-pass filtering the strong motion data, iteratively rotating the two horizontal components from an individual borehole station and cross-correlating them with that from a co-located surface station has proven to be very effective. In cases where the iterative cross-correlation method does not provide a good fit, rotating both surface and borehole stations to a common axis of maximum seismic energy provides an alternative approach. The orientation-offset of a borehole station relative to the surface station may be estimated by iteratively rotating the horizontal components of both and calculating the time-integral of the amplitude squared of each component; the difference in orientation between the maximum at the surface and at depth indicates the difference in orientation of the seismometers. After the horizontal orientations of borehole seismometers are correctly resolved, these data can be used in various scientific studies. Up-going and reflected down-going shear waves can be clearly identified, providing an excellent dataset for the study of interval velocity and seismic Q, localized shear wave splitting, and anisotropy. Further refinement of the geophysical structure of Taipei Basin and Northern Taiwan is also possible by combining data from the SMDA with that from the large array of surface stations maintained by the Central Weather Bureau.

    Epalrestat (Kinedak) is an aldose reductase inhibitor (ARI) for diabetic peripheral neuropathy. In 41 diabetics, we conducted a questionnaire survey to evaluate symptoms of peripheral neuropathy and select appropriate drug therapy. We investigated 27 patients who participated in the first and second questionnaire surveys. We reviewed questionnaire items, and examined the correlation between the therapeutic effects and responses to the questionnaire. Concerning the usefulness of the questionnaire items, some questions were correlated with the effects. Treatment was effective for somatic neuropathy, but not for autonomic neuropathy. The questionnaire regarding diabetic peripheral neuropathy was useful for somatic neuropathy screening, but it was difficult to detect autonomic neuropathy. PMID:19797880

    Individuals may develop symptoms in response to inhaled odors, chemicals, and irritants. This may affect their quality of life. Little is known about the prevalence and severity of symptoms that result from exposure to odors, chemicals and irritants. This study demonstrates the development of a new respiratory questionnaire to detect the prevalence and severity of symptoms experienced upon exposure to

    Objective. To further evaluate the adequacy of the items in our questionnaire aimed at unraveling the possible correlations between psychological features and internal disorders. This paper is dedicated to the items exploring the individual’s interaction with other people. Method. The items are divided into several subdomains. For each subdomain, we have calculated the correlations between the items of the respective subdomain (inner associations) and with the items in other subdomains (outer associations) by means of chi square test or Fisher exact test as dictated by statistical reasons. We examined the answers from our first 10192 respondents. Results and conclusions. Many inter-item correlations are the consequence of higher or lesser degrees of synonymy. Those within a given subdomain confirm the adequate allocation of items. Those bridging different subdomains may point either to incorrect assignments, or to semantic inclusion relations. Other results are not explicable by semantic similarity, and probably reveal psychological subtleties, such as: most individuals have a sense of undeservedness when badly treated by other people; those easily hurt by insults and humiliations have a propensity to timidity and/or emotivity; the subjects who shun conflicts are more prone to persistent thoughts, brooding people are more sensitive and more prone to conflicts, injustice-indignant people frequently get into conflict although they declare to be bothered by dissent etc. But at the heart of all the PFs in the Interaction-with-other-people domain there seems to be the sense of being undervalued, which should probably be the key issue to be addressed by any therapeutic interventions for diseases psychoemotionally determined by disturbed interpersonal relationships.

    In this paper we present the process of Knowledge Elicitation through a structured questionnaire technique. This is an effort to depict a problem domain as Investigation of factors affecting taskforce productivity. The problem has to be solved using the expert system technology. This problem is the very first step how to acquire knowledge from the domain experts. Knowledge Elicitation is one of the difficult tasks in knowledge base formation which is a key component of expert system. The questionnaire was distributed among 105 different domain experts of Public and Private Organizations (i.e. Education Institutions, Industries and Research etc) in Pakistan. A total 61 responses from these experts were received. All the experts were well qualified, highly experienced and has been remained the members for selection committees a number of times for different posts. Facts acquired were analyzed from which knowledge was extracted and elicited. A standard shape was given to the questionnaire for further research as a knowledge learning tool. This tool may be used as a standard document for selection and promotion of employees.

  17. The Caregiver Burden Questionnaire for Heart Failure (CBQ-HF): face and content validity

    PubMed Central

    2013-01-01

    Background A new caregiver burden questionnaire for heart failure (CBQ-HF v1.0) was developed based on previously conducted qualitative interviews with HF caregivers and with input from HF clinical experts. Version 1.0 of the CBQ-HF included 41 items measuring the burden associated with caregiving in the following domains: physical, emotional/psychological, social, and impact on caregiver’s life. Following initial development, the next stage was to evaluate caregivers’ understanding of the questionnaire items and their conceptual relevance. Methods To evaluate the face and content validity of the new questionnaire, cognitive interviews were conducted with caregivers of heart failure patients. The cognitive interviews included a “think aloud” exercise as the patient completed the CBQ-HF, followed by more specific probing questions to better understand caregivers’ understanding, interpretation and the relevance of the instructions, items, response scales and recall period. Results Eighteen caregivers of heart failure patients were recruited. The mean age of the caregivers was 50 years (SD?=?10.2). Eighty-three percent of caregivers were female and most commonly the patient was either a spouse (44%) or a parent (28%). Among the patients 55% were NYHA Class 2 and 45% were NYHA Class 3 or 4. The caregiver cognitive interviews demonstrated that the CBQ-HF was well understood, relevant and consistently interpreted. From the initial 41 item questionnaire, fifteen items were deleted due to conceptual overlap and/or item redundancy. The final 26-item CBQ-HF (v3.0) uses a 5-point Likert severity scale, assessing 4 domains of physical, emotional/psychological, social and lifestyle burdens using a 4-week recall period. Conclusions The CBQ-HF (v3.0) is a comprehensive and relevant measure of subjective caregiver burden with strong content validity. This study has established that the CBQ-HF (v3.0) has strong face and content validity and should be valuable as an outcomes measure to help understand and monitor the relationship between patient heart failure severity and caregiver burden. A Translatability AssessmentSM of the measure has since been performed confirming the cultural appropriateness of the measure and psychometric validation is planned for the future to further explore the reliability, and validity of the new questionnaire in a larger caregiver sample.

    2011-01-01

    Researchers use the Caregiver’s Feeding Styles Questionnaire (CFSQ) to categorize parent feeding into authoritative, authoritarian, indulgent, and uninvolved styles. The CFSQ assesses self-reported feeding and classifies parents using median splits, which are used in a substantial body of parenting literature and allow for direct comparison across studies, on dimensions of demandingness and responsiveness. No national norms currently exist for the CFSQ. This paper establishes and recommends cutoff points most relevant for low-income, minority US samples researchers and clinicians can use to assign parents to feeding styles. Median scores for 5 studies are examined and the average across these studies reported. PMID:22119478

    Free-ranging African elephants are highly social animals that live in a society where age, size, kinship, and disposition all contribute to social rank. Although captive elephant herds are small and largely comprises of unrelated females, dominance hierarchies are common. The goal of this study was to delineate how the behavior of captive female African elephants varies with respect to age and social rank based on a combination of keeper questionnaires and behavioral observations. "Body movements" and "trunk to" behaviors of 33 nonpregnant female African elephants housed at 14 North American zoos were recorded over 8 hr. Keepers at each facility also rated each elephant based on a series of questions about interactions with herdmates. The assessment of social rank based on observations correlated strongly with ranks assigned by keepers via the questionnaires. Observations and questionnaire responses indicated that body weight of the female, and to a lesser extent age, were significantly related to rates and types of "body movements" and that these demographic factors dictate the captive elephant hierarchy, similar to that observed in the wild. Many of the observed "body movements," such as back away, displace, push, and present, were correlated with keeper questionnaire responses about elephant interactions. However, none of the "trunk to" behaviors were related to age, size, or questionnaire responses even though they occurred frequently. In conclusion, we demonstrated that short-term behavioral observations and keeper questionnaires provided similar behavioral profiles for female African elephants housed in North American zoos.

    Objective Our objective was to determine whether a questionnaire can identify subjects with vitamin D insufficiency (VDI). Design Subjects completed the vitamin D and sun (VIDSUN) questionnaire and we measured their serum 25(OH)D levels. We assessed the sensitivity and specificity of the questionnaire to identify VDI (25(OH)D level <50 nmol/L). Setting Clinical Research Unit, University of Wisconsin-Madison Subjects Postmenopausal women Results We recruited 609 postmenopausal women with a mean ± SD age of 61 ± 6 years, of whom 113 (19%) had VDI. Subjects with VDI were more likely to be Black (17% vs. 2%, p<0.001), heavier (BMI 33±7 kg/m2 vs. 29±7 kg/m2, p<0.001) and less likely to tan in the past year (49% vs. 72%, p<0.001), use sunscreen (57% vs. 72%, p<0.001) or report sun exposure in the last three months. They consumed less vitamin D from supplements (86±210 vs. 188±344 IU/day, p=0.003). In logistic regression models, Black race, BMI, suntan within one year, sun exposure in the past three months, sunscreen use and supplemental vitamin D intake were the most useful questions to identify VDI. From these six items, a composite score ?2.25 demonstrated ?89% sensitivity but ?35% specificity for VDI. Conclusion The VIDSUN questionnaire provides an initial tool to identify postmenopausal women at high or low risk of VDI. Existing studies suggest that inclusion of physical activity and triglyceride levels might improve the performance of the VIDSUN questionnaire. PMID:23870503

    The aim of the present study was to investigate time-across stability of different factor solutions (two to six factors) of the Driver Behaviour Questionnaire (DBQ) and to examine the changes on self-reported driving pattern in a follow-up sample (n=622) after three years of the first responses. Repeated measures ANOVA indicated that there was a significant change between Time 1 and Time 2 scores in six items of the DBQ. Drivers reported less competitiveness while driving at Time 2 but more speeding, drinking and driving, driving to wrong destinations and having no recollection of the road just travelled. Significant Time x Sex x Age interactions were found in change scores of four items. Young males and middle-aged female drivers emerged as a group of drivers who changed their self-reported driving pattern over three years. Additionally, sex, age or both had main effects on scores of 21 items. Males and young drivers reported more violations than females and older drivers, whereas female drivers reported more errors and lapses. After running possible factor solutions with Tucker's Phi agreement coefficients, the results indicated that the four- and two-factor solutions were the most stable and interpretable ones. The two-factor solution showed better time-across stability than the four-factor structure did, although the factor solutions found at Time 1 and Time 2 were not as identical as expected. Separate analysis revealed that drivers who had high annual mileage at Time 1 and Time 2 showed the strongest two-factor time-across stability. The test-retest reliability was 0.50 for errors, 0.76 for violations and 0.61 for the whole scale. PMID:16310749

    The adipocyte-derived hormone leptin plays a critical role in the central transmission of energy balance to modulate reproductive function. However, the neurocircuitry underlying this interaction remains elusive, in part due to incomplete knowledge of first-order leptin-responsive neurons. To address this gap, we explored the contribution of predominantly inhibitory (GABAergic) neurons versus excitatory (glutamatergic) neurons in the female mouse by selective ablation of the leptin receptor in each neuronal population: Vgat-Cre;Leprlox/lox and Vglut2-Cre;Leprlox/lox mice, respectively. Female Vgat-Cre;Leprlox/lox but not Vglut2-Cre;Leprlox/lox mice were obese. Vgat-Cre;Leprlox/lox mice had delayed or absent vaginal opening, persistent diestrus, and atrophic reproductive tracts with absent corpora lutea. In contrast, Vglut2-Cre;Leprlox/lox females exhibited reproductive maturation and function comparable to Leprlox/lox control mice. Intracerebroventricular administration of kisspeptin-10 to Vgat-Cre;Leprlox/lox female mice elicited robust gonadotropin responses, suggesting normal gonadotropin-releasing hormone neuronal and gonadotrope function. However, adult ovariectomized Vgat-Cre;Leprlox/lox mice displayed significantly reduced levels of Kiss1 (but not Tac2) mRNA in the arcuate nucleus, and a reduced compensatory luteinizing hormone increase compared with control animals. Estradiol replacement after ovariectomy inhibited gonadotropin release to a similar extent in both groups. These animals also exhibited a compromised positive feedback response to sex steroids, as shown by significantly lower Kiss1 mRNA levels in the AVPV, compared with Leprlox/lox mice. We conclude that leptin-responsive GABAergic neurons, but not glutamatergic neurons, act as metabolic sensors to regulate fertility, at least in part through modulatory effects on kisspeptin neurons.

    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.

    2013-01-01

    Background The Otitis Media-6 questionnaire (OM-6) is the most frequently used instrument to measure health related quality of life in children with otitis media. The main objectives of this study are 1) to translate and cross-culturally adapt the OM-6 into Danish, and 2) to assess important psychometric properties including structural validity and interpretability of the OM-6 in a Danish population of children suffering from otitis media. Methods The OM-6 was translated and cross-culturally adapted according to international guidelines. A longitudinal validation study enrolled 491 children and their families, and the measurement properties of the OM-6 were evaluated using the Cosmin taxonomy. The properties assessed were construct and structural validity (confirmatory factor analysis) including internal consistency, reproducibility (test-retest reliability and smallest detectable change), responsiveness and interpretability. Results A total of 435 children were eligible to participate in the study. Analyses of structural validity and internal consistency indicated that parent appraisal of hearing and speech problems may be problematic. Both scales showed similarly good test-retest reliability and construct validity, were able to discriminate between diagnostic subgroups and responsive to change. Cut-off values of 16.7 and 30.0 were found to represent minimal important change for the patients. Conclusions The Danish version of the OM-6 is a reliable, valid, responsive and interpretable questionnaire to measure quality of life in children with otitis media. This study sheds light on possible weaknesses of the instrument that needs to be acknowledged in the utilization of the instrument. However, despite these issues our results support the continuing use of OM-6 as a 1-factor functional health scale with a separate global health rating. Furthermore, indications of values representing minimal important change as perceived by the respondent are presented. PMID:24257471

    Background Tinnitus research in an international context requires standardized and validated questionnaires in different languages. The aim of the present set of analyses was the reassessment of basic psychometric properties according to classical test theory of self-report instruments that are being used within the multicentre Tinnitus Research Initiative (TRI) database project. Methods 1318 patients of the TRI Database were eligible for the analyses. The basic psychometric properties reliability, validity, and sensitivity of Tinnitus Handicap Inventory (THI), Tinnitus Questionnaire (TQ) and Tinnitus Beeinträchtigungs Fragebogen (i.e., Tinnitus Impairment Questionnaire, TBF-12) were assessed by the use of Cronbach’s alpha, corrected item-total correlations, correlation coefficients and standardized response means. Results Throughout the languages, all questionnaires showed high internal consistencies (Cronbach’s alpha > 0.79) and solid item-total correlations, as well as high correlations among themselves (around 0.8) and in combination with the self-reported tinnitus severity. However, some paradoxical correlations between individual items of the TBF-12, constructed as a shortform of the THI, and the corresponding THI-items were seen. Standardized Response Means (SRM) were low if tinnitus did not change, and between 0.3 and 1.09 for improved or worsened tinnitus complaints, indicating the sensitivity of the measures. Conclusions All investigated instruments have high internal consistency, high convergence and discriminant validity and good change sensitivity in an unselected large multinational clinical sample and thus appear appropriate to evaluate the effects of tinnitus treatments in a cross-cultural context.

    The present study investigated the factor structure of parent and teacher Autism Spectrum Screening Questionnaire (ASSQ) in a population of 7-9 years old children. For validation purposes, factors derived were correlated with results on the Strengths and Difficulties Questionnaire (SDQ). A three-factor solution was identified on both parent and teacher ASSQ. Most of the variance was explained by one factor including measures of social function, validated by a high correlation with the SDQ peer problems scale. The second factor included measures of autism-associated problems. The items allocated to the third factor were more specific for a cognitive style typically found in high-functioning individuals with autism/Asperger syndrome. This factor did not correlate highly with any of the SDQ subscales. The results indicated that the screening efficiency of ASSQ could be increased by closer examination of the individual profile of factor scores. PMID:18178599

    111 Participants, recruited from Amazon's MTurk worker pool, completed Kirby's (2009) monetary choice questionnaire, which involves choosing between immediate, but smaller rewards and delayed, but larger rewards. Individual participants' responses were scored in three ways: first, by calculating the proportion of choices of the delayed rewards; second; using the scoring procedure described by Kirby et al. (1999) to estimate discounting rate (i.e., the value of the k-parameter in a hyperbolic discounting function); and third, using logistic regression to estimate discounting rate (Wileyto et al., 2004). Individuals' scores calculated using the proportion measure and the logarithms of their estimated k values were very strongly correlated (rs>.97). In addition, the proportions of choices of small, medium, and large amounts of the delayed rewards were strongly correlated (rs>.80). Taken together, these results suggest that the relative ease of calculating the proportion measure does not require sacrificing reliability. Moreover, the proportion measure is atheoretical and very easy to calculate whereas estimating an individual's discounting rate requires assuming a theoretical model that may not be appropriate. Significant differences in the proportion of delayed reward choices were observed between the small, medium, and large delayed reward amounts, with smaller rewards being discounted more steeply than larger ones, replicating previous findings of magnitude effects. These results provide further validation of the proportion of delayed reward choices on the Kirby questionnaire as a measure of individual and group differences in discounting. PMID:25139835

    Research on eating behaviour has identified several potentially relevant eating-related traits captured by different questionnaires. Often, these questionnaires predict Body Mass Index (BMI), but the relationship between them has not been explicitly studied. We studied the unity and diversity of questionnaires capturing five common eating-related traits: Power of Food, Eating Impulsivity, emotional eating, Disinhibition, and binge eating in women from Estonia (n?=?740) and Canada (n?=?456). Using bifactor analysis, we showed that a) these questionnaires are largely explained by a single factor, and b) relative to this shared factor, only some questionnaires offered additional variance in predicting BMI. Hence, these questionnaires seemed to characterise a common factor, which we label Uncontrolled Eating. Item Response Theory techniques were then applied to demonstrate that c) within this common factor, the questionnaires could be placed on a continuum of Uncontrolled Eating. That is, Eating Impulsivity focused on the milder degree, Power of Food Scale, emotional eating scales, and Disinhibition on intermediate degrees, and the Binge Eating Scale on the most severe degrees of Uncontrolled Eating. In sum, evidence from two samples showed that questionnaires capturing five common BMI-related traits largely reflected the same underlying latent trait - Uncontrolled Eating. In Estonia, some questionnaires focused on different severities of this common construct, supporting a continuum model of Uncontrolled Eating. These findings provide a starting point for developing better questionnaires of the neurobehavioural correlates of obesity, and provide a unifying perspective from which to view the existing literature. R scripts and data used for the analysis are provided. PMID:25769975

    1992-01-01

    Over the last three decades, multiwall structures have been analyzed extensively, primarily through experiment, as a means of increasing the protection afforded to spacecraft structure. However, as structural configurations become more varied, the number of tests required to characterize their response increases dramatically. As an alternative, numerical modeling of high-speed impact phenomena is often being used to predict the response of a variety of structural systems under impact loading conditions. This paper presents the results of a preliminary numerical/experimental investigation of the hypervelocity impact response of multiwall structures. The results of experimental high-speed impact tests are compared against the predictions of the HULL hydrodynamic computer code. It is shown that the hypervelocity impact response characteristics of a specific system cannot be accurately predicted from a limited number of HULL code impact simulations. However, if a wide range of impact loadings conditions are considered, then the ballistic limit curve of the system based on the entire series of numerical simulations can be used as a relatively accurate indication of actual system response.

  10. The pornography craving questionnaire: psychometric properties.

    Kraus, Shane; Rosenberg, Harold

    2014-04-01

    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.

    2013-08-01

    It was investigated whether pharmacogenetic factors, both as single polymorphism and as gene-gene interactions, have an added value over non-genetic factors in predicting statin response. Five common polymorphisms were selected in apolipoprotein E, angiotensin-converting enzyme, hepatic lipase and toll-like receptor 4. Linear regression models were built and compared on R(2) to estimate the added value of single polymorphisms and gene-gene interactions. The selected polymorphisms and the gene-gene interactions had a small added value in predicting change in low-density lipoprotein cholesterol levels (LDL-c) as response to statins over the non-genetic predictors (P=0.104), and also in predicting LDL-c in non-treated patients (P=0.016). Moreover, four gene-gene interactions with statin therapy were identified. The added value of genetic factors over non-genetic variables is for the greater part produced by gene-gene interactions. This underlines the importance to examine gene-gene interactions in future (pharmaco)genetic research. PMID:22547143

    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.

    Purpose The Oxford Participation and Activities Questionnaire is a patient-reported outcome measure in development that is grounded on the World Health Organization International Classification of Functioning, Disability, and Health (ICF). The study reported here aimed to inform and generate an item pool for the new measure, which is specifically designed for the assessment of participation and activity in patients experiencing a range of health conditions. Methods Items were informed through in-depth interviews conducted with 37 participants spanning a range of conditions. Interviews aimed to identify how their condition impacted their ability to participate in meaningful activities. Conditions included arthritis, cancer, chronic back pain, diabetes, motor neuron disease, multiple sclerosis, Parkinson’s disease, and spinal cord injury. Transcripts were analyzed using the framework method. Statements relating to ICF themes were recast as questionnaire items and shown for review to an expert panel. Cognitive debrief interviews (n=13) were used to assess items for face and content validity. Results ICF themes relevant to activities and participation in everyday life were explored, and a total of 222 items formed the initial item pool. This item pool was refined by the research team and 28 generic items were mapped onto all nine chapters of the ICF construct, detailing activity and participation. Cognitive interviewing confirmed the questionnaire instructions, items, and response options were acceptable to participants. Conclusion Using a clear conceptual basis to inform item generation, 28 items have been identified as suitable to undergo further psychometric testing. A large-scale postal survey will follow in order to refine the instrument further and to assess its psychometric properties. The final instrument is intended for use in clinical trials and interventions targeted at maintaining or improving activity and participation.

    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.

    Transcription factors that play a role in ossification during development are expected to participate in postnatal fracture repair since the endochondral bone formation that occurs in embryos is recapitulated during fracture repair. However, inherent differences exist between bone development and fracture repair, including a sudden disruption of tissue integrity followed by an inflammatory response. This raises the possibility that repair-specific transcription factors participate in bone healing. Here, we assessed the consequence of loss of early growth response gene 1 (EGR-1) on endochondral bone healing because this transcription factor has been shown to modulate repair in vascularized tissues. Model fractures were created in ribs of wild type (wt) and EGR-1?/? mice. Differences in tissue morphology and composition between these two animal groups were followed over 28 post fracture days (PFDs). In wt mice, bone healing occurred in healing phases characteristic of endochondral bone repair. A similar healing sequence was observed in EGR-1?/? mice but was impaired by alterations. A persistent accumulation of fibrin between the disconnected bones was observed on PFD7 and remained pronounced in the callus on PFD14. Additionally, the PFD14 callus was abnormally enlarged and showed increased deposition of mineralized tissue. Cartilage ossification in the callus was associated with hyper-vascularity and -proliferation. Moreover, cell deposits located in proximity to the callus within skeletal muscle were detected on PFD14. Despite these impairments, repair in EGR-1?/? callus advanced on PFD28, suggesting EGR-1 is not essential for healing. Together, this study provides genetic evidence that EGR-1 is a pleiotropic regulator of endochondral fracture repair. PMID:21726677

    The 62-item Multidimensional Experiential Avoidance Questionnaire (MEAQ) was recently developed to assess a broad range of experiential avoidance (EA) content. However, practical clinical and research considerations made a briefer measure of EA desirable. Using items from the original 62-item MEAQ, a 15-item scale was created that tapped content from each of the MEAQ's six dimensions. Items were selected on the basis of their performance in 3 samples: undergraduates (n = 363), psychiatric outpatients (n = 265), and community adults (n = 215). These items were then evaluated using 2 additional samples (314 undergraduates and 201 psychiatric outpatients) and cross-validated in 2 new, independent samples (283 undergraduates and 295 community adults). The resulting measure (Brief Experiential Avoidance Questionnaire; BEAQ) demonstrated good internal consistency. It also exhibited strong convergence with respect to each of the MEAQ's 6 dimensions. The BEAQ demonstrated expected associations with measures of avoidance, psychopathology, and quality of life and was distinguishable from negative affectivity and neuroticism. PMID:24059474

    Understanding the reasons for self-harm (SH) may be paramount for the identification and treatment of SH behavior. Presently, the psychometric properties for SH reason questionnaires are generally unknown or tested only in non-inpatient samples. Existing inpatient measures may have limited generalizability and do not examine SH apart from an explicit intent to die. The present study examined a newly developed, self-report measure of reason for self-harm. The Self-Harm Reasons Questionnaire (SHRQ) was administered to 143 undergraduate students. Results indicated that SH reasons covaried in meaningful and internally consistent ways, with subgroups of SH reasons correlating with hypothesized concomitants of SH, such as depressive symptoms. Findings have implications for prevention and intervention and the SHRQ offers a new, albeit preliminary, means by which to examine SH reasons in a non-inpatient sample. PMID:18355112

    Because no information exists on the prevalence of chemical sensitivity syndromes such as multiple chemical sensitivities, a questionnaire for use in population studies was developed and tested to assess the presence or absence of chemical sensitivity. Seven hundred five individuals attending clinics answered a questionnaire asking whether each of 122 common substances caused symptoms. Results showed that patients with multiple chemical sensitivities and asthma had average total scores that were significantly different from each other and from those of each of the other diagnostic categories. Higher total scores were also reported by female patients. The instrument described here may facilitate meaningful prevalence studies of multiple chemical sensitivities. It will also allow study of chemically induced symptoms in other conditions such as asthma. PMID:7702128

    Background To create and find accurate and reliable instruments for the measurement of physical activity has been a challenge in epidemiological studies. We investigated the reliability and validity of two different physical activity questionnaires in 71 adolescents aged 13–18 years; the WHO, Health Behaviour in Schoolchildren (HBSC) questionnaire, and the International Physical Activity Questionnaire (IPAQ, short version). Methods The questionnaires were administered twice (8–12 days apart) to measure reliability. Validity was assessed by comparing answers from the questionnaires with a cardiorespiratory fitness test (VO2peak) and seven days activity monitoring with the ActiReg, an instrument measuring physical activity level (PAL) and total energy expenditure (TEE). Results Intraclass correlation coefficients for reliability for the WHO HBSC questionnaire were 0.71 for frequency and 0.73 for duration. For the frequency question, there was a significant difference between genders; 0.87 for girls and 0.59 for boys (p < 0.05). The intraclass correlation coefficients the IPAQ varied between 0.10 and 0.62 for the reliability. Spearman correlation coefficients for validity for both the WHO HBSC questionnaire and the IPAQ (recoded into low, moderate and high activity) measured against VO2peak were fair, ranging between 0.29 – 0.39. The WHO HBSC questionnaire measured against VO2peak for girls were acceptable, ranging between 0.30 – 0.55. Both questionnaires, except the walking question in IPAQ, showed a low correlation with PAL and TEE, ranging between 0.01 and 0.29. Conclusion These data indicate that the WHO HBSC questionnaire had substantial reliability and were acceptable instrument for measuring cardiorespiratory fitness, especially among girls. None of the questionnaires however seemed to be a valid instrument for measuring physical activity compared to TEE and PAL in adolescents. PMID:18627632

    Background The aspects of consultation that are important for psychiatric patients have always remained a less acknowledged area. The aim of this study was to identify these aspects. Methods A Cross-sectional, questionnaire based study was carried out in a psychiatry outpatient clinic of two tertiary care hospitals in a developing country. The patients were asked to fill out the questionnaire containing a total of 11 close-ended questions plus 1 open-ended question. They graded them as not important, important, very important or do not know. Non-psychotic patients aged 18 and above, visiting the clinic were recruited into the study before they went in for their first consultation. Results The response rate of patients was 84%. More than 90% wanted the doctor to tell them the cause of their illness, talk to them about their condition, provide symptomatic relief, let them know that how long their illness would last and make the final decision about their treatment plan. Less than 20% wanted to be part of a support network. A significant 82% wanted talking therapy as part of their treatment plan. Conclusion The three issues, most important for patients were: the doctor should listen to them, make the final decision about treatment and provide symptomatic relief. Only 20% wanted to be a part of patients' support group. PMID:18312641

    Despite the critical role that terrestrial vegetation plays in the Earth's carbon cycle, very little is known about the potential evolutionary responses of plants to anthropogenically induced increases in concentrations of atmospheric CO2. We present experimental evidence that rising CO2 concentration may have a direct impact on the genetic composition and diversity of plant populations but is unlikely to result in selection favoring genotypes that exhibit increased productivity in a CO2-enriched atmosphere. Experimental populations of an annual plant (Abutilon theophrasti, velvetleaf) and a temperate forest tree (Betula alleghaniensis, yellow birch) displayed responses to increased CO2 that were both strongly density-dependent and genotype-specific. In competitive stands, a higher concentration of CO2 resulted in pronounced shifts in genetic composition, even though overall CO2-induced productivity enhancements were small. For the annual species, quantitative estimates of response to selection under competition were 3 times higher at the elevated CO2 level. However, genotypes that displayed the highest growth responses to CO2 when grown in the absence of competition did not have the highest fitness in competitive stands. We suggest that increased CO2 intensified interplant competition and that selection favored genotypes with a greater ability to compete for resources other than CO2. Thus, while increased CO2 may enhance rates of selection in populations of competing plants, it is unlikely to result in the evolution of increased CO2 responsiveness or to operate as an important feedback in the global carbon cycle. However, the increased intensity of selection and drift driven by rising CO2 levels may have an impact on the genetic diversity in plant populations. PMID:11607574

    2011-01-01

    Factors such as strabismus or anisometropia during infancy can disrupt normal visual development and result in amblyopia, characterized by reduced visual function in an otherwise healthy eye and often associated with persistent suppression of inputs from the amblyopic eye by those from the dominant eye. It has become evident from fMRI studies that the cortical response to stimulation of the amblyopic eye is also affected. We were interested to compare the hemodynamic response function (HRF) of early visual cortex to amblyopic vs. dominant eye stimulation. In the first experiment, we found that stimulation of the amblyopic eye resulted in a signal that was both attenuated and delayed in its time to peak. We postulated that this delay may be due to suppressive effects of the dominant eye and, in our second experiment, measured the cortical response of amblyopic eye stimulation under two conditions--where the dominant eye was open and seeing a static pattern (high suppression) or where the dominant eye was patched and closed (low suppression). We found that the HRF in response to amblyopic eye stimulation depended on whether the dominant eye was open. This effect was manifested as both a delayed HRF under the suppressed condition and an amplitude reduction. PMID:22186274

    We comprehensively compared all available questionnaires for measuring quantitative autistic traits (QATs) in terms of reliability and construct validity in 3,147 non-clinical and 60 clinical subjects with normal intelligence. We examined four full-length forms, the Subthreshold Autism Trait Questionnaire (SATQ), the Broader Autism Phenotype Questionnaire, the Social Responsiveness Scale2-Adult Self report (SRS2-AS), and the Autism-Spectrum Quotient (AQ). The SRS2-AS and the AQ each had several short forms that we also examined, bringing the total to 11 forms. Though all QAT questionnaires showed acceptable levels of test-retest reliability, the AQ and SRS2-AS, including their short forms, exhibited poor internal consistency and discriminant validity, respectively. The SATQ excelled in terms of classical test theory and due to its short length. PMID:24342972

    This study was conducted because a real method for measuring safety climate had never been developed and assessed in Serbian industry. The aim of this paper was to start the process of developing a safety climate questionnaire that could be used in Serbia. As a starting point a 21-item questionnaire was adopted after an extensive literature review. The questionnaire was distributed at several Serbian factories; 1098 workers responded. After a statistical analysis of the data obtained with the questionnaire and a critical comparison with the available reference results, a final questionnaire with 21 questions, divided into 7 groups, was developed. The 7 groups of questions (factors) were safety awareness and competence, safety communication, organizational environment, management support, risk judgment and management reaction, safety precautions and accident prevention, and safety training.

    The aim of this study was the development and psychometric assessment of a questionnaire for functions of OCD (FFZ). The instrument was analyzed using factor and item analyses with a sample of 120 OCD patients within the first 5 weeks of an inpatient cognitive-behavioral treatment. The revealed scales were OCD as self-confirmation, emotion regulation, avoidance of responsibility, interpersonal regulation and OCD as occupation. The reliabilities of all subscales and the total value were satisfactory to nearly excellent. The factorial validity was good, content validity was excellent. The FFZ shows correlations with measures of interpersonal problems and emotional competence, but none with measures of self-reflection and therapy experience. No differences were found for gender or age. The results provide initial support for the reliability and validity of the FFZ. PMID:25584864

    In 1928, the Library of Virginia inherited a mass of materials from the Virginia War History Commission, which had spent the previous eight years gathering information on Virginia's participation in World War I. Included in this material were over 14,900 four-page questionnaires from a survey of WWI veterans in Virginia. The Library of Virginia has digitized these survey forms and created a free, fully-searchable database. Users have three search options: by word or phrase, combination, and expert/boolean. Search returns offer basic information on each individual, and users must follow the link at the bottom of the page to download the digitized images (in .tif format) of the questionnaire forms. In some cases, respondents submitted photos or additional pages with their forms and these are included in the database.

    Classical methods for detecting outliers deal with continuous variables. These methods are not readily applicable to categorical data, such as incorrect\\/correct scores (0\\/1) and ordered rating scale scores (e.g., 0, …, 4) typical of multi-item tests and questionnaires. This study proposes two definitions of outlier scores suited for categorical data. One definition combines information on outliers from scores on all

    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.

    The current study assessed the reliability and validity of the Health Care Alliance Questionnaire, which was developed using a Delphi process and embedded in an ongoing perinatal outcomes study. The Health Care Alliance Questionnaire exhibited content and face validity and high reliability. Results indicated concurrent validity in relation to satisfaction with practitioner and discriminant validity in relation to interpersonal sensitivity and posttraumatic stress disorder. The Health Care Alliance Questionnaire demonstrated predictive validity in relation to perceptions of practitioner's care during labor and postpartum depression. Overall, results suggest that alliance may be an important factor in maternity care processes and outcomes. Further psychometric work is warranted. PMID:24155197

    BACKGROUND Safety culture has been identified as having a major impact on how safety is managed in healthcare. However, it has not received much attention in general practices. Hence, no instrument yet exists to assess safety climate-the measurable artefact of safety culture-in this setting. This study aims to evaluate psychometric properties of a newly developed safety climate questionnaire for use in German general practices. METHODS The existing Safety Attitudes Questionnaire, Ambulatory Version, was considerably modified and enhanced in order to be applicable in general practice. After pilot tests and its application in a random sample of 400 German practices, a first psychometric analysis led to modifications in several items. A further psychometric analysis was conducted with an additional sample of 60 practices and a response rate of 97.08%. Exploratory factor analysis with orthogonal varimax rotation was carried out and the internal consistency of the identified factors was calculated. RESULTS Nine factors emerged, representing a wide range of dimensions associated with safety culture: teamwork climate, error management, safety of clinical processes, perception of causes of errors, job satisfaction, safety of office structure, receptiveness to healthcare assistants and patients, staff perception of management, and quality and safety of medical care. Internal consistency of factors is moderate to good. CONCLUSIONS This study demonstrates the development of a patient safety climate instrument. The questionnaire displays established features of safety climate and additionally contains features that might be specific to small-scale general practices. PMID:21571753

    It is generally recognized that there is a need for improved teaching of nutrition in medical schools and for increased education of the general population. A questionnaire, derived in part from a study of physician knowledge, was administered to first year medical students in order to assess their knowledge of various aspects of nutrition and metabolism, and as a teaching tool to transmit information about the subject. The performance of first year students was consistent with a generally educated population but there were surprising deficits in some fundamental areas of nutrition. Results of the questionnaire are informative about student knowledge, and immediate reinforcement from a questionnaire may provide a useful teaching tool. In addition, some of the subject matter can serve as a springboard for discussion of critical issues in nutrition such as obesity and markers for cardiovascular disease. A major barrier to improved teaching of nutrition is the lack of agreement on some of these critical issues and there are apparent inconsistencies in recommendations of government and health agencies. It seems reasonable that improved teaching should address the lack of knowledge of nutrition, rather than knowledge of official guidelines. Student awareness of factual information should be the primary goal. PMID:15649324

    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

    Objective The aim of this study was to translate the Women's Health Questionnaire (WHQ) into the Serbian language and assess its validity and reliability in a population of Serbian menopausal women. Methods The study included peri- and postmenopausal women from two Community Health Centers in Belgrade. Women filled out the WHQ, the Short Form-36 questionnaire (SF-36) and Beck's Depression Inventory (BDI). The WHQ was translated according to recommended methodology for cultural adaptation of questionnaires and its psychometric characteristics (internal consistency, inter-rater reliability, factor analysis, sensitivity, discriminant, construct and criterion validity) were tested. Results In the Serbian population, the mean values of the WHQ domains were mostly comparable with reference Mediterranean countries. Whole-scale Cronbach's ? was 0.838. Moreover, five WHQ domains had a value of Cronbach's ? above the acceptable limit. There were no significant differences in WHQ scores between our two investigators. On exploratory factor analysis, we obtained ten factors (two items formed a new factor - 'Menstrual pathology'). Almost all SF-36 domains were significantly associated with WHQ domains, while the BDI was associated with domains: depressive mood, anxiety and sleep problems. Based on ROC analysis, WHQ is slightly more reliable for perimenopausal than postmenopausal Serbian women. Conclusion The Serbian version of the WHQ showed very good reliability and validity in assessment of quality of life among menopausal women. The WHQ is applicable for both peri- and postmenopausal women. PMID:25373408

    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.

    The present study describes the development of the German short version "Fragebogen zu interpersonellen Schuldgefühlen" (FIS) of the "Interpersonal Guilt Questionnaire" (IGQ) developed by O'Connor et al. The questionnaire was used in a representative sample of 652 eastern and 1283 western Germans. Woman show higher scores on the subscales "Seperation Guilt" and "Omnipotent Responsibility Guilt" than man. Eastern Germans mark higher scores on the subscale "Omnipotent Responsibility Guilt" than western Germans. Correlations between interpersonal guilt and social anxiety and differences between a non-clinical and a clinical sample show that maladaptive aspects of guilt feelings can be assessed by the "Interpersonal Guilt Questionnaire".

    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.

    OBJECTIVES. This study was undertaken to test the acceptability of preventive services under Medicare waivers to a community-dwelling population aged 65 and over and to examine the effect of such services on health. METHODS. Medicare beneficiaries and designated primary care providers were sampled, and beneficiaries were screened and surveyed. A total of 4195 individuals were then randomized into intervention or control groups. Those in the intervention group were offered free preventive visits (under waivers) to their physicians. A follow-up survey of the entire group was administered after completion of the intervention. RESULTS. Sixty-three percent of the intervention group made a preventive clinical visit, and about half of them a counseling visit. For men, being married and having a solo practitioner were positively associated with accepting the intervention services, while for women, having had a mammogram, having a confidant, having a high school education, and having a female practitioner were so associated. The intervention group showed a greater health benefit than did the control group and had a significantly lower death rate: 8.3% vs 11.1%. CONCLUSIONS: Older individuals will respond to preventive programs, and such services will result in modest health gains. PMID:7892923

    Purpose The aim of this study was to determine the diagnostic value of three screening questionnaires in identifying Korean patients at high risk for obstructive sleep apnea (OSA) in a sleep clinic setting in Korea. Materials and Methods Data were collected from 592 adult patients with suspected OSA who visited a sleep center. All patients completed the Sleep Apnea of Sleep Disorder Questionnaire (SA-SDQ), the Berlin questionnaire, and the STOP-Bang questionnaire. Estimated OSA risk was compared to a diagnosis of OSA. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated for each questionnaire. Results The prevalence of OSA was 83.6% using an apnea-hypopnea index (AHI) ?5/h and 58.4% for an AHI ?15/h. The STOP-Bang questionnaire had a high sensitivity (97% for AHI ?5/h, 98% for AHI ?15/h), but the specificity was low (19% and 11%, respectively). In contrast, the sensitivity of the SA-SDQ was not high enough (68% for AHI ?5/h, 74% for AHI ?15/h) to be useful in a clinical setting, whereas the specificity was relatively good (66% and 61%, respectively). The sensitivity and specificity values of the Berlin questionnaire fell between those of the STOP-Bang questionnaire and the SA-SDQ. Conclusion The STOP-Bang questionnaire may be useful for screening OSA in a sleep clinic setting, but its specificity is lower than the acceptable level for this purpose. A new screening questionnaire with a high sensitivity and acceptable specificity is therefore needed in a sleep clinic setting. PMID:25837173

    Reentry analyses consisting of ablation response, thermal response and thermal stress response have been conducted on the Light Weight Radioisotope Heater Unit for Galileo/VEEGA reentry conditions. Sequential ablation analyses of the LWRHU aeroshell, the fuel clad, and the fuel pellet have been conducted in reentry regimes where the aeroshell has been deemed to fail. The failure criterion for ablation is assumed to be recession corresponding to 50% of the wall thickness (the design criterion recommended in the DOE Overall Safety Manual). Although the analyses have been carried far beyond this limit (as presented and discussed herein), JHU/APL endorses the position that failure may occur at the time that this recession is achieved or at lower altitudes within the heat pulse considering the uncertainties in the aerodynamic, thermodynamic, and thermo-structural analyses and modeling. These uncertainties result mainly because of the high energies involved in the VEEGA reentries compared to orbital decay reentries. Risk evaluations should consider the fact that for shallow flight paths the unit may disassemble at high-altitude as a result of ablation or may remain intact until it impacts with a clad that had been molten. 80 refs., 46 figs., 16 tabs.

    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

Method Six classes of predictor and moderator variables (22 variables) were identified from the literature and examined using continuous (Pediatric Anxiety Ratings Scale; PARS) and categorical (Clinical Global Impression Scale-Improvement; CGI-I) outcome measures. Results Three baseline variables predicted better outcomes (independent of treatment condition) on the PARS, including low anxiety severity (as measured by parents and independent evaluators) and caregiver strain. No baseline variables were found to predict week 12 responder status (CGI-I). Participant's principal diagnosis moderated treatment outcomes, but only on the PARS. No baseline variables were found to moderate treatment outcomes on week 12 responder status (CGI-I). Discussion Overall, anxious children responded favorably to CAMS treatments. However, having more severe and impairing anxiety, greater caregiver strain, and a principal diagnosis of social phobia were associated with less favorable outcomes. Clinical implications of these findings are discussed. PMID:24417601

    Background The Michigan Hand Questionnaire (MHQ) is one of the most widely utilized, hand-specific surveys that measures health status relevant to patients with acute and chronic hand disorders. However, item redundancy exists in the original version, and an abbreviated survey could minimize responder burden and offer broader applicability. Methods Patients (n=422) with 4 specific hand conditions completed the MHQ at two time periods: rheumatoid arthritis (RA) (n=162), thumb carpometacarpal osteoarthritis (CMC) (n=31), carpal tunnel syndrome (CTS) (n=97), and distal radius fracture (DRF) (n=132). Correlation analysis identified 2 items from each of 6 domains (function, activities of daily living, work, pain, aesthetics, and satisfaction). A brief-MHQ score was calculated as the sum of the responses to the 12 items. Psychometric analysis was performed to describe the reliability, validity, and responsiveness of the brief MHQ. Results The brief-MHQ includes 12 items that were highly correlated with the summary MHQ score (r= 0.99, p<0.001). The brief MHQ scores were highly correlated between the two time periods (r =0.78, p<0.001), and by disease type. Responsiveness of the brief MHQ was high for all diseases, and similar to that of the original MHQ. Conclusions The 12-item brief MHQ is an efficient and versatile outcomes instrument specific to hand disability that retains the psychometric properties of the original MHQ. The brief MHQ is an important tool to measure patient outcomes and the quality of care in hand surgery. PMID:21701336

    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

    2013-01-01

    Background Patient safety has been a priority in primary healthcare in the last years. The prevailing culture is seen as an important condition for patient safety in practice and several tools to measure patient safety culture have therefore been developed. Although Dutch primary care consists of different professions, such as general practice, dental care, dietetics, physiotherapy and midwifery, a safety culture questionnaire was only available for general practices. The purpose of this study was to modify and validate this existing questionnaire to a generic questionnaire for all professions in Dutch primary care. Methods A validated Dutch questionnaire for general practices was modified to make it usable for all Dutch primary care professions. Subsequently, this questionnaire was administered to a random sample of 2400 practices from eleven primary care professions. The instrument’s factor structure, reliability and validity were examined using confirmatory and explorative factor analyses. Results 921 questionnaires were returned. Of these, 615 were eligible for factor analysis. The resulting SCOPE-PC questionnaire consisted of seven dimensions: ‘open communication and learning from errors’, ‘handover and teamwork’, ‘adequate procedures and working conditions’, ‘patient safety management’, ‘support and fellowship’, ‘intention to report events’ and ‘organisational learning’ with a total of 41 items. All dimensions had good reliability with Cronbach’s alphas ranging from 0.70 – 0.90, and the questionnaire had a good construct validity. Conclusions The SCOPE-PC questionnaire has sound psychometric characteristics for use by the different professions in Dutch primary care to gain insight in their safety culture. PMID:24044750

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

    NASA Astrophysics Data System (ADS)

    2012-12-01

    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.

    Purpose: To evaluate the efficacy of amifostine in diminishing radiotherapy side effects and whether or not it protects the tumor. Methods and Materials: We performed a systematic review and meta-analysis of 14 included randomized controlled trials, comprising 1451 patients, comparing the use of radiotherapy vs. radiotherapy plus amifostine for cancer treatment. Results: The use of amifostine significantly reduced the risk of developing mucositis (odds ratio [OR], 0.37; 95% confidence interval [CI], 0.29-0.48; p < 0.00001), esophagitis (OR, 0.38; CI, 0.26-0.54; p < 0.00001), acute xerostomia (OR, 0.24; CI, 0.15-0.36; p < 0.00001), late xerostomia (OR, 0.33; CI, 0.21-0.51; p < 0.00001), dysphagia (OR, 0.26; CI, 0.07-0.92; p 0.04), acute pneumonitis (OR, 0.15; CI, 0.07-0.31; p < 0.00001) and cystitis (OR, 0.17; CI, 0.09-0.32; p < 0.00001). There was no difference in overall response rate between the groups. However, complete response rate was superior for patients using amifostine (OR, 1.81; CI, 1.10-2.96; p = 0.02). Conclusions: This systematic review shows that amifostine significantly reduces the side effects of radiation therapy. The efficacy of radiotherapy was not itself affected by the use of this drug and patients receiving amifostine were able to achieve higher rates of complete response.

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

    PubMed Central

    2014-01-01

    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

    2014-01-01

    Background/Objectives The use of internet-based questionnaires to collect information from older adults is not well established. This systematic literature review of studies using online questionnaires in older adult populations aims to 1. describe methodologic approaches to population targeting and sampling and 2. summarize limitations of Internet-based questionnaires in geriatric populations. Design, Setting, Participants We identified English language articles using search terms for geriatric, age 65 and over, Internet survey, online survey, Internet questionnaire, and online questionnaire in PubMed and EBSCO host between 1984 and July 2012. Inclusion criteria were: study population mean age ?65 years old and use of an online questionnaire for research. Review of 336 abstracts yielded 14 articles for full review by 2 investigators; 11 articles met inclusion criteria. Measurements Articles were extracted for study design and setting, patient characteristics, recruitment strategy, country, and study limitations. Results Eleven (11) articles were published after 2001. Studies had populations with a mean age of 65 to 78 years, included descriptive and analytical designs, and were conducted in the United States, Australia, and Japan. Recruiting methods varied widely from paper fliers and personal emails to use of consumer marketing panels. Investigator-reported study limitations included the use of small convenience samples and limited generalizability. Conclusion Online questionnaires are a feasible method of surveying older adults in some geographic regions and for some subsets of older adults, but limited Internet access constrains recruiting methods and often limits study generalizability.

    2009-03-01

    This paper presents the results of the 2008 UT modeling benchmark with the ultrasonic simulation code for predicting echo-responses from flaws integrated into the Civa software platform and with the code developed by M. Spies. UT configurations addressed are similar to 2007 ones, to better understand some responses obtained last year. Experimental results proposed concern the responses of flat bottom holes at different depths inside surface curved blocks inspected by an immersion probe in normal incidence. They investigate the influence of surface curvature upon the amplitude and shape of flaw responses. Comparison of the simulated and experimental results is discussed.

  4. Vitiligo-inducing phenols activate the unfolded protein response in melanocytes resulting in upregulation of IL6 and IL8.

    Vitiligo is characterized by depigmented skin patches caused by loss of epidermal melanocytes. Oxidative stress may have a role in vitiligo onset, while autoimmunity contributes to disease progression. In this study, we sought to identify mechanisms that link disease triggers and spreading of lesions. A hallmark of melanocytes at the periphery of vitiligo lesions is dilation of the endoplasmic reticulum (ER). We hypothesized that oxidative stress results in redox disruptions that extend to the ER, causing accumulation of misfolded peptides, which activates the unfolded protein response (UPR). We used 4-tertiary butyl phenol and monobenzyl ether of hydroquinone, known triggers of vitiligo. We show that expression of key UPR components, including the transcription factor X-box-binding protein 1 (XBP1), is increased following exposure of melanocytes to phenols. XBP1 activation increases production of immune mediators IL6 and IL8. Co-treatment with XBP1 inhibitors reduced IL6 and IL8 production induced by phenols, while overexpression of XBP1 alone increased their expression. Thus, melanocytes themselves produce cytokines associated with activation of an immune response following exposure to chemical triggers of vitiligo. These results expand our understanding of the mechanisms underlying melanocyte loss in vitiligo and pathways linking environmental stressors and autoimmunity. PMID:22696056

    The document is the result of a cooperative research effort involving scientists from several agencies as part of the Aquatic Effects Research Program (AERP) of the U.S. Environmental Protection Agency (EPA). The Episodic Response Project (ERP) is an intensive study conducted at a limited number of sites, rather than an extensive regional study. The three areas targeted by the ERP are the Northern Appalachian Plateau of Pennsylvania, and the Adirondack and Catskill Mountains of New York. Each stream was monitored from fall 1988 through spring 1990, with continuous measurement of discharge and automated water sampling at fixed time intervals or at specified stage level changes. The water samples underwent chemical analysis for acid neutralizing capacity (ANC), pH, total dissolved aluminum, dissolved organic carbon (DOC), sulfate, nitrate, chloride, calcium, magnesium, potassium, and sodium. Furthermore, a subset of samples were analyzed for inorganic aluminum. Specific streams, participating institutions and cooperators, methods, and results are presented in the report.

    Objective The phenomenon of foot binding, also known as ‘lotus feet’, has an enduring and influential history in China. To achieve a man-made smaller foot size, lifelong foot binding may have had adverse effects on the skeleton. We investigated bone properties in postmenopausal women with bound feet, which may provide new information for developing countermeasures for prevention of fragility fractures. Design Population-based cohort study. Participants This study involved 254 postmenopausal women aged 65–80, including 172 with bound feet and 82 age- and gender-matched control subjects, living in a remote region of China. Outcomes Anthropometric, SF-36 Lifestyle Questionnaire and heel quantitative ultrasound (QUS) data were collected for the whole study population. A small subset of two cases was also invited for assessment of bone mineral density and microarchitecture at the distal tibia using high-resolution peripheral quantitative CT (HR-pQCT) and gait and balance tests. Results Women with bound feet had significantly lower QUS values than age-matched women with normal feet; this was supported by HR-pQCT data. However, SF-36 Questionnaire results did not reveal any statistically significant differences in any categorical responses, including physical functioning, general health vitality and physical component summary score, and number of previous fractures. No impairment of body balance was found in the small subset. Conclusions The man-made changes caused by foot binding led to reduced physical activity, making the subjects prone to osteoporosis. Women with bound feet and osteoporosis did not have a higher incidence of fragility fractures than controls. This might be explained by compensation in physical activity to improve body balance, implying the importance of improving or maintaining body balance in overall prevention strategies against fragility fractures.

    Online game is an increasingly popular source of entertainment for all ages, with relatively prevalent negative consequences. Addiction is a problem that has received much attention. This research aims to develop a measure of online game addiction for Indonesian children and adolescents. The Indonesian Online Game Addiction Questionnaire draws from earlier theories and research on the internet and game addiction. Its construction is further enriched by including findings from qualitative interviews and field observation to ensure appropriate expression of the items. The measure consists of 7 items with a 5-point Likert Scale. It is validated by testing 1,477 Indonesian junior and senior high school students from several schools in Manado, Medan, Pontianak, and Yogyakarta. The validation evidence is shown by item-total correlation and criterion validity. The Indonesian Online Game Addiction Questionnaire has good item-total correlation (ranging from 0.29 to 0.55) and acceptable reliability (??=?0.73). It is also moderately correlated with the participant's longest time record to play online games (r?=?0.39; p<0.01), average days per week in playing online games (??=?0.43; p<0.01), average hours per days in playing online games (??=?0.41; p<0.01), and monthly expenditure for online games (??=?0.30; p<0.01). Furthermore, we created a clinical cut-off estimate by combining criteria and population norm. The clinical cut-off estimate showed that the score of 14 to 21 may indicate mild online game addiction, and the score of 22 and above may indicate online game addiction. Overall, the result shows that Indonesian Online Game Addiction Questionnaire has sufficient psychometric property for research use, as well as limited clinical application. PMID:23560113

  8. Forced response of the East Asian summer rainfall over the past millennium: results from a coupled model simulation

    2011-01-01

    The centennial-millennial variation of the East Asian summer monsoon (EASM) precipitation over the past 1000 years was investigated through the analysis of a millennium simulation of the coupled ECHO-G model. The model results indicate that the centennial-millennial variation of the EASM is essentially a forced response to the external radiative forcing (insolation, volcanic aerosol, and green house gases). The strength of the response depends on latitude; and the spatial structure of the centennial-millennial variation differs from the interannual variability that arises primarily from the internal feedback processes within the climate system. On millennial time scale, the extratropical and subtropical precipitation was generally strong during Medieval Warm Period (MWP) and weak during Little Ice Age (LIA). The tropical rainfall is insensitive to the effective solar radiation forcing (insolation plus radiative effect of volcanic aerosols) but significantly responds to the modern anthropogenic radiative forcing. On centennial time scale, the variation of the extratropical and subtropical rainfall also tends to follow the effective solar radiation forcing closely. The forced response features in-phase rainfall variability between the extratropics and subtropics, which is in contrast to the anti-correlation on the interannual time scale. Further, the behavior of the interannual-decadal variation in the extratropics is effectively modulated by change of the mean states on the millennial time scale, suggesting that the structure of the internal mode may vary with significant changes in the external forcing. These findings imply that on the millennial time scale, (a) the proxy data in the extratropical EA may more sensitively reflect the EASM rainfall variations, and (b) the Meiyu and the northern China rainfall provide a consistent measure for the EASM strength.

  11. Developing questionnaires for educational research: AMEE Guide No. 87

    PubMed Central

    La Rochelle, Jeffrey S.; Dezee, Kent J.; Gehlbach, Hunter

    2014-01-01

    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

    Background/Aim Certain host genetic polymorphisms reportedly affect the likelihood of a sustained virological response (SVR) to interferon treatment in subjects infected with hepatitis C virus (HCV). As part of the HALT-C trial we evaluated genetic associations among patients infected with HCV genotype 1 who had failed previous interferon treatment. Methods SVR was determined 24 weeks after completing treatment with pegylated interferon alfa-2a and ribavirin. Eight single nucleotide polymorphisms (SNPs) were selected on the basis of previously reported associations with treatment response. Genotypes were assessed by polymerase chain reaction-based assays. The percentage of patients who achieved SVR was determined for each genotype and for an IL-10 promoter diplotype. Results Among 637 non-Hispanic Caucasian patients there were no significant associations between genotype for any individual SNP (IL10 -1082, IL10 -592, TNF -308, TNF -238, TGFB1 codon 25, CCL2 -2518, EPHX1 codon 113 and AGT -6) and SVR, but SVR was more common among the patients who were homozygous for the ACC IL-10 promoter diplotype (adjusted odds ratio, 3.24; 95% confidence interval, 1.33–7.78; p=0.001). Conclusions Among non-Hispanic Caucasian patients treated with peginterferon and ribavirin after failing previous treatment with interferon, homozygosity for the ACC IL-10 promoter diplotype was associated with SVR.

    The Fukushima Daiichi nuclear power facility, in the Futaba District of the Fukushima Prefecture in Japan, was severely damaged by the earthquake and ensuing tsunami that struck off the northern coast of the island of Honshu on March 11, 2011. The resulting structural damage to the plant disabled the reactor's cooling systems and led to significant, ongoing environmental releases of radioactivity, triggering a mandatory evacuation of a large area surrounding the plant. The status of the facility continues to change, and permanent control of its radioactive inventory has not yet been achieved. The purpose of this educational article is to summarize the short-term chronology, radiologic consequences, emergency responses, and long-term challenges associated with this event. Although there is ongoing debate on preparedness before the event and the candor of responsible entities in recognizing and disclosing its severity, it largely appears that appropriate key actions were taken by the Japanese authorities during the event that should mitigate any radiologic health impact. These actions include an organized evacuation of over 200,000 inhabitants from the vicinity of the site and areas early in the emergency; monitoring of food and water and placement of radiation limits on such foodstuffs; distribution of stable potassium iodide; and systematic scanning of evacuees. However, the risk of additional fuel damage and of further, perhaps substantial, releases persists. The situation at the Fukushima Daiichi nuclear facility remains fluid, and the long-term environmental and health impact will likely take years to fully delineate. PMID:21799088

    Background/Aims A self-report questionnaire is frequently used to measure symptoms reliably and to distinguish patients with functional gastrointestinal disorders (FGIDs) from those with other conditions. We produced and validated a cross-cultural adaptation of the Rome III questionnaire for diagnosis of FGIDs in Korea. Methods The Korean version of the Rome III (Rome III-K) questionnaire was developed through structural translational processes. Subsequently, reliability was measured by a test-retest procedure. Convergent validity was evaluated by comparing self-reported questionnaire data with the subsequent completion of the questionnaire by the physician based on an interview and with the clinical diagnosis. Concurrent validation using the validated Korean version of the Short Form-36 Health Survey (SF-36) was adopted to demonstrate discriminant validity. Results A total of 306 subjects were studied. Test-retest reliability was good, with a median Cronbach's ? value of 0.83 (range, 0.71-0.97). The degree of agreement between patient-administered and physician-administered questionnaires to diagnose FGIDs was excellent; the ? index was 0.949 for irritable bowel syndrome, 0.883 for functional dyspepsia and 0.927 for functional heartburn. The physician's clinical diagnosis of functional dyspepsia showed the most marked discrepancy with that based on the self-administered questionnaire. Almost all SF-36 domains were impaired in participants diagnosed with one of these FGIDs according to the Rome III-K. Conclusions We developed the Rome III-K questionnaire though structural translational processes, and it revealed good test-retest reliability and satisfactory construct validity. These results suggest that this instrument will be useful for clinical and research assessments in the Korean population. PMID:24199012

    OBJECTIVES—Health related quality of life (HRQOL) inventories are multi-dimensional measures of patient-centred health status developed for clinical research. The MS quality of life 54 (MSQOL-54) is an MS-specific HRQOL inventory originally devised for English speaking patients. It consists of a core measure, the 36-item short form health survey (SF-36) previously adapted into Italian, and 18 additional items exploring domains relevant to patients with MS (MS-18 module). The authors translated and culturally adapted into Italian the MS-18 module of the MSQOL-54 questionnaire, and clinically validated the whole questionnaire.?METHODS—The MS-18 module was translated following the methodology of the International Quality of Life Assessment (IQOLA) project. The MSQOL-54 was validated in 204 consecutive patients with MS seen between April and September 1997 at three participating centres. The questionnaire was explained by the physician who also administered the expanded disability status scale (EDSS) and mini mental status scale examination, and the patient filled in the MSQOL-54 and Beck depression inventory questionnaires (BDI), with assistance if required. The contribution of impairments and disabilities to MSQOL-54 scores were assessed, and mean scores were compared with normative data for the general Italian population, and with the original sample of United States MS patients.?RESULTS—The mean age of the 204 patients was 42 years; mean EDSS score was 4.5 (range 0-8.5). Patients' participation in the assessment was satisfactory, and all scales satisfied the usual psychometric standards. The characteristics of the United States sample matched those of our patients in all but gender (72% United States patients v 52% Italian patients were women), and education (90% United States patients and 44% Italian patients completed high school); MSQOL-54 profiles were also similar. The EDSS was significantly associated with the physical health composite but not with the mental health composite score. Multiple linear regression modelling showed that age and BDI independently predicted physical health composite (p < 0.001), and mental health composite (p < 0.001). Clinical worsening in the previous year had an independent effect on the physical health composite (p < 0.001).?CONCLUSIONS—The Italian version of MSQOL-54 is easy to administer and is well accepted by patients. Neurological impairment has a limited influence on perceived quality of life, while age and depressive symptoms has a major influence.?? PMID:10406981

    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.

    Background/Aims The patient-centered medical home (PCMH) is widely supported as a means to coordinate care in the primary care environment, but relatively little is known about how variation in implementation of a PCMH model influences the success and sustainability. Many survey instruments developed to date for assessing PCMH are aimed at the healthcare system design as a whole or at patient experience, but not at providers who may have varying attitudes and perspectives on the role of PCMH and unique insights into practical implementation issues. Our goal was to develop questionnaires aimed at primary care physicians (PCPs) and nurse case managers (CMs) to assess variation in perception and implementation of PCMH. Methods This study was performed within Geisinger Health System, an integrated health system with a PCMH program first introduced in 2006. We reviewed care management, medical home, chronic illness and chronic care model literature, and existing tools such as Patients Assessment of Chronic Illness Care (PACIC). Based on 60-minute interviews with system leadership about program design, we developed pilot questions and completed 90-minute interviews with 3 highly-experienced nurse CMs to map global concepts of services and systems to individual staff member functions. Two structured questionnaires were developed for CMs and PCPs focusing on team interactions, linkages to outside resources, and tasks/responsibilities. Providers were asked to rate difficulty of various functions as well as their perceived impact on patient care. Results We administered questionnaires during 60-minute semi-structured interviews with 47 clinical staff covering 23 medical home clinics. Case managers and physicians showed strong agreement on who bears responsibility for ensuring patient access (PCP), monitoring and linkages (CM) and education (Shared), but there was wide variation among clinics in perceived difficulty and impact of various tasks, particularly connecting patients with community resources and interacting with external nursing home facilities in different areas. Results of other questionnaire areas will be presented. Conclusions Design characteristics, process measures and patient-level outcomes are all important in assessing benefits of a PCMH program, and this work contributes additional tools for measuring provider perspectives and variation in implementation across different PCMH sites.

    In the last years, intimate partner violence (IPV) became a relevant problem for community and for social life, particularly in young people. Its correct assessment and evaluation in the population is mandatory. Our objectives were: Confirm factor structure of Dating Violence Questionnaire (DVQ) and investigate its convergent and divergent validity. The DVQ along with other personality measures were filled by a sample of 418 university students (Females = 310) of average age of 23 y.o. (SD = 4.71). A subsample of participants (223 students) consented in being involved also in retest and filled also the Revised Eysenck Personality Questionnaire (short form) and a brief scale for describing the behavior of the (past) partner after the breaking of the relationship (BRS). The 8-factor structure, with respect to the two other competing models, reported better fit indexes and showed significant correlations with other personality measures. Personality traits, both Neuroticism and Psychoticism, correlated with Sexual Violence, while Detachment correlated only with Neuroticism and Coercion, Humiliation and Physical Violence correlated with only Psychoticism. Extraversion did not report significant relationships with any of the 8 DVQ factors. Also the predictive validity of DVQ was satisfactory with the partner violent reaction to the break of relationship predicted positively predicted by Coercion (b = 0.22) and by Humiliation (b = 0.20) and negatively by Emotional Punishment (b = -0.18). The present results indicate a good factor structure of the questionnaire, and interesting correlations with personality traits, allowing to identify psychological aspects with a predisposing role for anti-social aggressive behaviors. Further studies will be aimed at ascertaining other possible determinants of intimate partner violence and the weight of cultural aspects. PMID:25992602

    Helicobacter pylori establishes lifelong infections of the gastric mucosa, a niche considered hostile to most microbes. While responses to gastric acidity and local inflammation are understood, little is known as to how they are integrated into homeostatic control of cell division and growth-stage gene expression. Here we investigate the essential orphan response regulator HP1043, a member of the OmpR/PhoB subfamily of transcriptional regulators that is unique to the Epsilonproteobacteria and that lacks phosphorylation domains. To test the hypothesis that conformational changes in the homodimer might lead to defects in gene expression, we sought mutations that might alter DNA-binding efficiency. Two introduced mutations (C215S, C221S) C terminal to the DNA-binding domain of HP1043 (HP1043CC11) resulted in a 2-fold higher affinity for its own promoter by footprinting. Modeling studies with the crystal structure of HP1043 suggested that C215S might affect the helix-turn-helix domain. Genomic replacement of the hp1043 allele with the hp1043CC11 mutant allele resulted in a 2-fold decrease in protein levels, despite a dramatic increase in mRNA. The mutations did not affect in vitro growth rates or colonization efficiency in a mouse model. Proteomic profiling (CC11 mutant strain versus wild type) identified many expression differences, and quantitative PCR further revealed that 11 out of 12 examined genes had lost growth-stage regulation and that 6 of the genes contained HP1043 binding consensus sequences within the promoter regions (fur, cagA, cag23, flhA, flip, and napA). Our studies show that mutations that affect DNA-binding affinity can be used to identify new members of the HP1043 regulon. PMID:23429531

    Invariant or Type 1 NKT cells (iNKT cells) are a unique population of lymphocytes that share characteristics of T cells and natural killer (NK) cells. Various studies have shown that positive costimulatory pathways such as the CD28 and CD40 pathways can influence the expansion and cytokine production by iNKT cells. However, little is understood about the regulation of iNKT cells by negative costimulatory pathways. Here, we show that in vivo activation with ?-GalCer results in increased cytokine production and expansion of iNKT cells in the absence of programmed cell death ligand-1 (PD-L1, B7-H1, and CD274). To study whether PD-L1 deficiency on NKT cells would enhance antigen-specific T-cell responses, we utilized CD8+ OT-1 OVA transgenic T cells. ?-GalCer enhanced the expansion and cytokine production of OT-1 CD8+ cells after adoptive transfer into wild-type recipients. However, this expansion was significantly enhanced when OT-1 CD8+ T cells were adoptively transferred into PD-L1?/? recipients. To extend these results to a tumor model, we used the B16 melanoma system. PD-L1?/? mice given dendritic cells loaded with antigen and ?-GalCer had a significant reduction in tumor growth and this was associated with increased trafficking of antigen-presenting cells and CD8+ T cells to the tumors. These data demonstrate that abrogating PDL1:PD-1 interactions during the activation of iNKT cells amplifies an anti-tumor response when coupled with DC vaccination. PMID:21240487

    A reliable and validated set of food safety behavior questions that could be used with confidence when evaluating food safety education programs was identified in this study. A list of 29 food-handling and consumption behaviors rank-ordered within five pathogen control factors by nationally recognized food safety experts was the basis for the development of the behavior questions. Questions were evaluated for reliability and several forms of validity. During a kitchen activity session, 70 graduates of a nutrition education program completed four food preparation tasks while being observed and videotaped. The individuals also participated in an in-depth interview to validate behaviors that could not be observed during the food preparation activity, e.g., refraining from preparing food for others when experiencing diarrhea. Criterion validity was established by comparing questionnaire responses to observed behavior and interview responses. Twenty-eight questions met the validity criterion (> or = 70% agreement between observed and interviewed responses and self-reported responses), with three or more questions from each of five pathogen control factor areas. Observation assessments revealed that hand washing was more likely to be performed prior to beginning food preparation than between working with raw meats and fresh produce. Errors in methods of washing hands, utensils, and preparation surfaces between food preparation tasks were common. Most participants did not use thermometers to evaluate doneness but still cooked to safe internal temperatures. The results provide a tool that educators can use to evaluate food safety programs and will help guide the development of more effective food safety education programs targeting needed improvements in behavioral skills.

    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

    The primary purpose of this study was to develop a self-report questionnaire to assess the driving violations of Chinese motorcycle riders and evaluate its screening accuracy between accident-involved and accident-free motorcycle riders. A Chinese Motorcycle Rider Driving Violation (CMRDV) scale, consisting of 19 items, was developed and administered to a sample of motorcycle riders (n=920). Exploratory factor analysis revealed a two-factor solution, which supported the theoretical premise that there are two types of driving violations, aggressive violations and ordinary violations, and that they also apply to motorcycle riders. Cronbach's alpha for these two sub-scales was between 0.876 and 0.914. The test-retest reliability was satisfactory with intra-class correlations of individual item scores ranging from 0.729 to 0.891. Respondents with a past history of active accidents scored significantly high than those without (p<0.0001). Overall, the area under the ROC curve was 0.715 (p<0.0001, 95% CI 0.670-0.760) at a cutoff score of 30.5 with sensitivity of 0.706 and specificity of 0.610. The results indicated that the CMRDV questionnaire was valid and reliable for measuring the driving violations of Chinese motorcycle riders. PMID:20441839

    Rationale, aims and objectives The prenatal education promotes the empowerment of parents during pregnancy and postnatal period. This study aimed to assess the quality of educational sessions held in the third trimester of pregnancy as part of the parenting education programme for Spanish National Health System in Madrid. Methods The design is a cross-sectional study in 41 primary care centres in the autonomous community of Madrid, which is one of the 17 autonomous communities that constitute the Spanish State, each wick medical responsibilities. The participants are a representative probability sample of 928 attendees to the programme. The assessment instrument is ‘EDUMA2’ questionnaire (Cronbach's alpha = 0.829) of 56 variables. Descriptive statistical analysis was performed using SPSS. The project was approved by the Research and Ethics Committees of the University Hospital of La Paz. Results The uptake efficiency immigration risk is 14.7%, and lack of social support is 8.7%. The functionality in organization, teaching and methodology is high in 90.5%. The learning effectiveness of health habits, care and techniques is significant and greater than 60% in the 14 parameters studied. Satisfaction is very high at 67.5%. The immediate impact in terms of control or safety increase is significant and greater than 71% and significantly greater than 40% and for increasing the bonding with the baby. Conclusions No jobs found with which to compare. The assessment of the programme with adequate psychometric characteristics questionnaire allows designing strategies and research to improve the quality of prenatal education. PMID:24819555

  6. Development of a food frequency questionnaire to estimate habitual dietary intake in Japanese children

    PubMed Central

    2010-01-01

    Background Food frequency questionnaires (FFQ) are used for epidemiological studies. Because of the wide variations in dietary habits within different populations, a FFQ must be developed to suit the specific group. To date, no FFQ has been developed for Japanese children. In this study, we developed a FFQ to assess the regular dietary intake of Japanese children. The FFQ included questions regarding both individual food items and mixed dishes. Methods Children (3-11 years of age, n = 621) were recruited as subjects. Their parents or guardians completed a weighed dietary record (WDR) for each subject in one day. We defined FOOD to be not only as a single food item but also as a mixed dish. The dieticians conceptually grouped similar FOODs as FOOD types. We used a contribution analysis and a multiple regression analysis to select FOOD types. Results We obtained a total of 586 children's dietary data (297 boys and 289 girls). In addition, we obtained 1,043 FOODs. Dieticians grouped into similar FOODs, yielding 275 FOOD types. A total of 115 FOOD types were chosen using a contribution analysis and a multiple regression analysis, then we excluded overlapping items. FOOD types that were eaten by fewer than 15 subjects were excluded; 74 FOOD types remained. We also added liver-based dishes that provided a high amount of retinol. A total of 75 FOOD types were finally determined for the FFQ. The frequency response formats were classified into four type categories: seven, eight, nine and eleven, according to the general intake frequency of each FOOD type. Information on portion size was obtained from the photographs of each listed FOOD type in real scale size, which was the average amount of the children's portion sizes. Conclusions Using both a contribution analysis and a multiple regression analysis, we developed a 75-food item questionnaire from the study involving 586 children. The next step will involve the verification of FFQ reproducibility and validity. PMID:20380735

    The aims of this study were to survey the knowledge and attitudes of Italian health care professionals toward pain and develop a valid instrument to assess pain knowledge of physicians and nurses. A 21-item questionnaire on a Likert scale was given to 4,961 health professionals in 20 hospitals in Italy who volunteered to participate in the study. The results were analyzed psychometrically in three phases: the Principal Component Analysis phase identified two components, of which only the one that had 10 items about pain knowledge and attitudes (PAK) was studied; the Homogeneity Analysis revealed its acceptable internal reliability (Cronbach's alpha=0.72) and confirmed the Likert equidistance of the item options response; and the Confirmatory Factor Analysis proved that it had a very good construct validity. A standardized score was calculated on the PAK questionnaire using the final 10 selected items, considering 100% as the best level of knowledge of pain management and 0% as the worst. The standardized mean score on the whole sample was equal to 52.6% (95% Confidence Interval: 52.3%-53.0%). There was a statistically significant difference (P<0.001) in percentage score between physicians (56.5%) and nurses (51.3%). Knowledge was best among physicians in Anesthesiology and Emergency; this was followed by doctors in Medicine and then surgeons. The knowledge of nurses was almost constant. This scale fills a void by providing a validated instrument for testing the general knowledge about pain treatment of hospital staff. It is brief and can easily be administered to a considerable number of people. PMID:17531913

    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.

    2012-01-01

    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

    Background Lifestyle assessment and intervention tools are useful in promoting pediatric weight management. The present study aimed to establish convergent validity and reliability for a quick simple measure of food intake and physical activity/sedentary behaviour. The HABITS questionnaire can be used to identify and monitor behavioural intervention targets. Methods Thirty-five youths (ages 7–16 years) were recruited from the waiting area of the Jacobi Medical Center Child and Teen Health Services. To establish convergent validity for the HABITS questionnaire, study participants completed the HABITS questionnaire, a 24-h recall and a modified version of the Modifiable Activity Questionnaire for Adolescents (MAQ). Participants completed a second HABITS questionnaire within 1 month to assess test–retest reliability. Internal consistency for dietary and physical activity/sedentary behaviour subscales was assessed using Cronbach’s alpha, and test–retest reliability was assessed using Cohen’s Kappa coefficient. Spearman’s rank correlation coefficients were calculated for individual items using the 24-h recall and the MAQ as reference standards. Results The HABITS questionnaire subscales showed moderate internal consistency (Cronbach’s alpha of 0.61 and 0.59 for the dietary and physical activity/sedentary behaviour subscale, respectively). The test–retest reliability was 0.94 for the dietary subscale and 0.87 for the physical activity/sedentary behaviour subscale. Several items on the HABITS questionnaire were moderately correlated with information reported in the MAQ and the 24-h recall (r = 0.38–0.59, P < 0.05). Conclusions The HABITS questionnaire can reliably be used in a paediatric setting to quickly assess key dietary and physical activity/sedentary behaviours and to promote behaviour change for weight management.

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

    PubMed Central

    2013-01-01

    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

    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

    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

  14. Does speed in completing an online questionnaire have an influence on its reliability?

    A common way to attract Internet users to complete an online questionnaire is to offer the opportunity to win money in a lottery. If participants hurry through the questionnaire to head for a reward, Cronbach's alpha, an indicator for internal consistency and therefore reliability of a questionnaire, could be affected, because these participants probably do not read the items carefully but instead click randomly through the questionnaire. We developed a system to measure the total time needed to complete the questionnaire in order to identify different groups of participants according to differences in fill-in time (speed). Five hundred seventy-five respondents participated in an online study testing the reliability of the Affective Neuroscience Personality Scales (ANPS). Results showed that speed has no influence on Cronbach's alpha with the exception of a lie scale, which consisted in contrast to the personality scales (12-14 items) only of five items. Only 2% of all participants were suspected to be cheaters with respect to the time spent on answering 110 items of the ANPS. Interestingly, Cronbach's alpha remained stable in this extremely fast group, which spent less than 2 SD below mean-completion time on the questionnaire. PMID:18954281

    Interleukin (IL)-10 is a regulator of inflammatory responses and is secreted by a variety of different cell types including T cells. T regulatory cells have been shown to suppress immune responses by IL-10–dependent, but also IL-10–independent, mechanisms. Herein, we address the role of T cell–derived IL-10 in mice with an inactivation of the IL-10 gene restricted to T cells generated by Cre/loxP-mediated targeting of the IL-10 gene. Splenocytes from this T cell–specific mutant secrete increased amounts of proinflammatory cytokines after activation in vitro compared with show enhanced contact hypersensitivity reactions, and succumb to severe immunopathology upon infection with Toxoplasma gondii. Despite intact IL-10 genes in other cell types, the dysregulation of T cell responses observed in the T cell–specific IL-10 mutant closely resembles the phenotype in complete IL-10 deficiency. However, in contrast to complete IL-10 deficiency, sensitivity to endotoxic shock and irritant responses of the skin are not enhanced in the T cell–specific IL-10 mutant. Our data highlight the importance of T cell–derived IL-10 in the regulation of T cell responses and demonstrate that endotoxic shock and the irritant response of the skin are controlled by IL-10 from other cell types.

    Recently, researchers have started to measure the working alliance repeatedly across sessions of psychotherapy, relating the working alliance to symptom change session by session. Responding to questionnaires after each session can become tedious, leading to careless responses and/or increasing levels of missing data. Therefore, assessment with the briefest possible instrument is desirable. Because previous research on the Working Alliance Inventory has found the separation of the Goal and Task factors problematic, the present study examined the psychometric properties of a 2-factor, 6-item working alliance measure, adapted from the Working Alliance Inventory, in 3 patient samples (ns = 1,095, 235, and 234). Results showed that a bifactor model fit the data well across the 3 samples, and the factor structure was stable across 10 sessions of primary care counseling/psychotherapy. Although the bifactor model with 1 general and 2 specific factors outperformed the 1-factor model in terms of model fit, dimensionality analyses based on the bifactor model results indicated that in practice the instrument is best treated as unidimensional. Results support the use of composite scores of all 6 items. The instrument was validated by replicating previous findings of session-by-session prediction of symptom reduction using the Autoregressive Latent Trajectory model. The 6-item working alliance scale, called the Session Alliance Inventory, is a promising alternative for researchers in search for a brief alliance measure to administer after every session.

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

    NASA Astrophysics Data System (ADS)

    Longo, Marcos

    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.

  1. Viral replication and paracrine effects result in distinct, functional responses of dendritic cells following infection with dengue 2 virus

    Dengue virus (DENV), a re-emerging arbovirus, readily infects dendritic cells (DC) in culture and in vivo. However, there have been contradictory reports regarding the effect of DENV infection on DC activation and maturation. DC undergo a series of functional changes following exposure to infectious agents, including cytokine production and costimulatory and MHC molecule induction, culminating in stimulation of adaptive immune responses. Immunological memory to primary DENV infection critically influences disease severity during subsequent infections with heterologous serotypes. To explore these phenomena, we examined DENV infection-dependent and -independent effects on DC secretory, phenotypic, and allostimulatory functions. DENV infection of DC resulted in the secretion of a broad array of cytokines and chemokines. Type I IFN produced by DC inhibited propagation of infection and induced the chemokine IFN-?-inducible protein 10 (IP-10; CXCL10). Based on intracellular cytokine staining, infected DC produced less IP-10 but more TNF-? than uninfected bystander cells in the same culture. DENV exposure activated surface molecule expression on infected and bystander cells; infected DC had enhanced programmed death ligand 2 (PD-L2) and MHC II expression but reduced levels of PD-L1, CD80, CD86, and MHC I relative to bystander DC. Dengue-infected DC cultures stimulated resting allogeneic CD4 T cell proliferation, although an increasing multiplicity of infection was associated with decreasing stimulatory capacity of DC. These data demonstrate that functional maturation of DC in response to dengue infection is modified by the presence of virus through IFN-dependent and -independent mechanisms with consequences for the development of adaptive immunity.

    This study investigated changes in motor skills and tissues of the upper extremity (UE) with regard to injury and inflammatory reactions resulting from performance of a voluntary forelimb repetitive reaching and grasping task in rats. Rats reached for food at a rate of 4 reaches/min, 2 h/day, and 3 days/week for up to 8 weeks during which reach rate, task duration and movement strategies were observed. UE tissues were collected bilaterally at weekly time points of 3-8 weeks and examined for morphological changes. Serum was tested for levels of interleukin-1?(IL-1) protein. The macrophage-specific antibody, ED1, was used to identify infiltrating macrophages and the ED2 antibody was used to identify resident macrophages. Rats were unable to maintain baseline reach rate in weeks 5 and 6 of task performance. Alternative patterns of movement emerged. Fraying of tendon fibrils was observed after 6 weeks in the mid-forelimb. After 4 weeks, a general elevation of ED1-IR macrophages were seen in all tissues examined bilaterally including the contralateral, uninvolved forelimb and hindlimbs. Significantly more resident macrophages were seen at 6 and 8 weeks in the reach limb. At 8 weeks, serum levels of IL-1? increased significantly above week 0. Our results demonstrate that performance of repetitive tasks elicits motor decrements, signs of injury and a cellular and tissue responses associated with inflammation. PMID:12507595

    Background The purpose of this study was to validate the Spanish and Catalan versions of the Diabetes Self-Care Inventory-Revised Version (SCI-R) questionnaire to assess the degree of adherence to self-care among adults with diabetes. Methods We validated the Spanish and Catalan translation from, and back translation to, English and cultural adaptation of the SCI-R in type 1 diabetes patients on multiple insulin doses or continuous subcutaneous insulin infusion and in type 2 diabetes patients on oral agents and/or insulin. Internal reliability, structural validity, and external validity (correlation with glycated hemoglobin) were evaluated. Responsiveness to change was assessed in patients 1 year after onset of type 1 diabetes and following a structured education program. Results The SCI-R presented good internal reliability Cronbach’s ?: 0.75, test-retest reliability (r = 0.82) and structural validity (r > 0.40). The external validity was also good; the SCI-R correlated with HbA1c in patients with type 1 diabetes on multiple insulin doses (r = ?0.50) or continuous subcutaneous insulin infusion (r = ?0.66) and in patients with type 2 diabetes on multiple insulin doses (r = ?0.62). However, it was not satisfactory in patients on oral agents (r = ?0.20) and/or bedtime insulin (r = ?0.35). Responsiveness to change was analyzed in 54 patients (age 27.3±7.4 years, 26% men, HbA1c 6.8% ±1.1%); the SCI-R score was 72.3% ±13.7% and correlated negatively with glycated hemoglobin (r = ?0.42) and 3 scales of the Diabetes Quality of Life questionnaire (lower score indicating better perception): Impact (r = ?0.37), Social Worry (r = ?0.36) and Diabetes Worry (r = ?0.38), all at P < 0.05. Conclusion The Spanish and Catalan versions of the SCI-R questionnaire show good psychometric properties and both could be considered as useful tools for evaluating self-care behavior in patients with type 1 or type 2 diabetes. However, there are still some subgroups of patients with type 2 diabetes in which the validity of this questionnaire needs further evaluation. PMID:24124352

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

    2014-01-01

    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

  6. Simulating Pacific Northwest Forest Response to Climate Change: How We Made Model Results Useful for Vulnerability Assessments

    GCM-based climate projections and downscaled climate data proliferate, and there are many climate-aware vegetation models in use by researchers. Yet application of fine-scale DGVM based simulation output in national forest vulnerability assessments is not common, because there are technical, administrative and social barriers for their use by managers and policy makers. As part of a science-management climate change adaptation partnership, we performed simulations of vegetation response to climate change for four national forests in the Blue Mountains of Oregon using the MC2 dynamic global vegetation model (DGVM) for use in vulnerability assessments. Our simulation results under business-as-usual scenarios suggest a starkly different future forest conditions for three out of the four national forests in the study area, making their adoption by forest managers a potential challenge. However, using DGVM output to structure discussion of potential vegetation changes provides a suitable framework to discuss the dynamic nature of vegetation change compared to using more commonly available model output (e.g. species distribution models). From the onset, we planned and coordinated our work with national forest managers to maximize the utility and the consideration of the simulation results in planning. Key lessons from this collaboration were: (1) structured and strategic selection of a small number climate change scenarios that capture the range of variability in future conditions simplified results; (2) collecting and integrating data from managers for use in simulations increased support and interest in applying output; (3) a structured, regionally focused, and hierarchical calibration of the DGVM produced well-validated results; (4) simple approaches to quantifying uncertainty in simulation results facilitated communication; and (5) interpretation of model results in a holistic context in relation to multiple lines of evidence produced balanced guidance. This latest point demonstrates the importance of using model out as a forum for discussion along with other information, rather than using model output in an inappropriately predictive sense. These lessons are being applied currently to other national forests in the Pacific Northwest to contribute in vulnerability assessments.

    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.

    'Scientific dishonesty' implies the fabrication, falsification or plagiarism in proposing, performing or reviewing research or in reporting research results. A questionnaire was given to postgraduate students at the medical faculties in Sweden who attended a course in research ethics during the academic year 2008/2009 and 58% answered (range 29%-100%). Less than one-third of the respondents wrote that they had heard about scientific dishonesty in the previous 12 months. Pressure, concerning in what order the author should be mentioned, was reported by about 1 in 10 students. We suggest that all departments conducting research should have a written policy about acceptable research behaviour and that all doctoral students should be informed of the content of this policy. Participants in the research groups concerned should also be required to analyse published articles about scientific dishonesty and critically discuss what could be done about unethical conduct.

    Background Drug addiction is considered as a problem of the new century which has destructive consequences for both family and society. This ominous phenomenon resulted from many factors. Present research aimed at recognition of inter-personal factors related to addiction and were conducted through a questionnaire to identify the youths at risk of addiction. Objectives Present research aimed at recognition of inter-personal factors related to addiction and were conducted through a questionnaire to identify the youths at risk of addiction. Materials and Methods The design of the present research is correlational analytic. The population consists of all young addicted or non-addicted people between the ages 18 to 35 and the sample consists of 82 addicted and 223 non-addicted young people in Tehran who were selected randomly and simply. The initial form included 120 questions which were administered on the sample in three stages. The data was analyzed through descriptive statistic and factor analysis. Results In this questionnaire four factors of depression and miserableness, having a positive attitude to drug, stress and anxiety and finally seeking high levels of excitement were respectively the strongest factors in predicting the risk of drug-abuse and addiction. The validity of the questionnaire which consists of 75 questions in the final form was calculated through internal consistency. Cronbach alpha of the whole questionnaire was 0.97, which that of the factor of depression and miserableness was 0.96, the factor of a positive attitude to drug was 0.93, the factor of stress and anxiety was 0.90 and the factor of high excitement-seeking was 0.80. Conclusions The evaluation of the questionnaire for identifying the individuals in the risk of addiction showed that the questionnaire benefits from appropriate validity and reliability. Therefore, it can be used in preventive fields and research. Moreover, by illuminating interpersonal factors that are effective in drug abuse, proper strategies can be used to prevent drug addiction.

    Workers in certain industries (e.g., agriculture) do not participate in a hearing conservation program and rarely receive this important preventive care. The National Institute for Deafness and Communication Disorders (NIDCD) has published a questionnaire to assess a person's need for medical examination of their hearing. The use of a self-administered questionnaire may pose a simple, low cost opportunity to assess the hearing health of workers not included in a hearing conservation program. However, the validity of the NIDCD questionnaire has not been tested. A study was conducted to compare the results of audiometric screening and the NIDCD questionnaire in identifying persons at risk for hearing impairment who may benefit from a medical referral. Data were collected from 103 farm operators at a regional farm show. Receiver-operator characteristic curves, measuring the ability of the questionnaire to correctly classify those with and without the disease suggested that the level of performance of the questionnaire as a whole, ranged from 0.74 to 0.69 (fair to poor). However, selected questionnaire items (e.g., Do you have to strain to understand conversations?) had moderate agreement (0.38 to 0.41) with screening audiogram results. Overall, the 10-item instrument did not perform as well as instruments with fewer items reported in separate studies. These findings suggest that, while less desirable than audiometry, alternative self-administered instruments might perform the better in this group. This approach may be useful as an alternative screening method to detect risk of hearing loss and identifying the need for medical evaluation of hearing sensitivity, particularly among farm operators.

    Dysphagia can have severe consequences for the patient's health, influencing health-related quality of life (HRQoL). Sound psychometric properties of HRQoL questionnaires are a precondition for assessing the impact of dysphagia, the focus of this study, resulting in recommendations for the appropriate use of these questionnaires in both clinical practice and research contexts. We performed a systematic review starting with a search for and retrieval of all full-text articles on the development of HRQoL questionnaires related to oropharyngeal dysphagia and/or their psychometric validation from the electronic databases PubMed and Embase published up to June 2011. Psychometric properties were judged according to quality criteria proposed for health status questionnaires. Eight questionnaires were included in this study. Four are aimed solely at HRQoL in oropharyngeal dysphagia: the deglutition handicap index (DHI), dysphagia handicap index (DHI'), M.D. Anderson Dysphagia Inventory (MDADI), and SWAL-QOL, while the EDGQ, EORTC QLQ-STO 22, EORTC QLQ-OG 25 and EORTC QLQ-H&N35 focus on other primary diseases resulting in dysphagia. The psychometric properties of the DHI, DHI', MDADI, and SWAL-QOL were evaluated. For appropriate applicability of HRQoL questionnaires, strong scores on the psychometric criteria face validity, criterion validity, and interpretability are prerequisites. The SWAL-QOL has the strongest ratings for these criteria, while the DHI' is the most easy to apply given its 25 items and the use of a uniform scoring format. For optimal use of HRQoL questionnaires in diverse settings, it is necessary to combine psychometric and utility approaches. PMID:24590284

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

    PubMed Central

    2014-01-01

    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. Results Adults with ASC reported more sensory hypersensitivity on the SPQ compared to controls (P?

    We examined the role of placebo response in acute mania trials. Specifically, whether placebo response: (1) predicts treatment effect, (2) can be predicted by patient and study characteristics, and (3) can be predicted by a parsimonious model. We performed a meta-analysis of individual patient data from 10 registration studies (n=1019) for the indication acute manic episode of bipolar disorder. We assessed the effect of 14 determinants on placebo response. Primary outcome measures were mean symptom change score (MCS) on the Young Mania Rating Scale (YMRS) and response rate (RR), defined as ?50% YMRS symptom improvement from baseline to endpoint. The overall placebo response was 8.5 points improvement on the YMRS (=27.9%) with a RR of 32.8%. Placebo response was significantly associated with the overall treatment response. Five determinants significantly (p<0.05) predicted the placebo response. The multivariate prediction model, which consisted of baseline severity, psychotic features at baseline, number of geographic regions, and region, explained 10.4% and 5.5% of the variance in MSC and RR, respectively. Our findings showed that the placebo response in efficacy trials of antipsychotics for acute mania is substantial and an important determinant of treatment effect. Placebo response is influenced by patient characteristics (illness severity and presence of psychotic features) and by study characteristics (study year, number of geographic regions and region). However, the prediction model could only explain the placebo response to a limited extent. Therefore, limiting trials to certain patients in certain geographic regions seems not a viable strategy to improve assay sensitivity. PMID:25907248

    Research has identified important psychometric differences between the original Depressive Experiences Questionnaire (DEQ; Blatt, D'Affliti, & Quinlan, 1976) and two of its most widely used revisions, which have failed to preserve the degree of between-scale orthogonality routinely observed with the original Dependency and Self-Criticism scales. The purpose of this study was (a) to examine construct validity for the recently developed McGill revision of the DEQ (Santor, Zuroff, & Fielding, this issue), which preserves between-scale orthogonality; (b) to compare the McGill revision of the DEQ with other existing revisions with respect to measures of personality, motivation, and interpersonal relatedness; and (c) to explore the correlates of items that appear to be responsible for maintaining the degree of orthogonality between measures of Dependency and Self-Criticism. Results suggest that (a) the McGill revision of the DEQ offers more valid estimates of the relations among dependency, self-criticism, and other theoretically relevant constructs, such as depressed mood and agreeableness, than other existing revisions and (b) items differentiating Dependency and Self-Criticism assess broad interpersonal orientations that can be characterized as communal or agentic. Results validate the newer McGill scales, further support the utility of the methods used in their development, and provide insights into the differences between Dependency and Self-Criticism.

    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 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

    Several questionnaires are available to evaluate illness perceptions in patients, such as the illness perception questionnaire revised (IPQ-R) and the brief version (Brief IPQ). This study aims to systematically review the literature concerning the clinimetric properties of the IPQ-R and the Brief IPQ in patients with musculoskeletal pain. The electronic databases Web of Sciences and PubMed were searched. Studies were included when the clinimetric properties of the IPQ-R or Brief IPQ were assessed in adults with musculoskeletal pain. Methodological quality was determined using the COSMIN checklist. Eight articles were included and evaluated. The methodological quality was good for 3 COSMIN boxes, fair for 11 and poor for 3 boxes. None of the articles obtained an excellent methodological score. The results of this review suggest that the IPQ-R is a reliable questionnaire, except for illness coherence. Internal consistency is good, except for the causal domain. The IPQ-R has good construct validity, but the factor structure is unstable. Hence, the IPQ-R appears to be a useful instrument for assessing illness perceptions, but care must be taken when generalizing the results of adapted versions of the questionnaires. The Brief IPQ shows moderate overall test-retest reliability. No articles examining the validity of the Brief IPQ were found. Further research should therefore focus on the content and criterion validity of the IPQ-R and the clinimetric properties of the Brief IPQ. PMID:25435470

    Data acquired during a test program which involved full-scale, sprinklered, compartment fires is presented and analyzed. This work focuses attention specifically on key features of the typical sprinkler link deployment/response problem. It is found that the elevated temperature, upper smoke layer which develops inevitably in compartment fires can have a major impact on the thermal response of sprinkler links. It is shown that traditionally accepted methods of predicting sprinkler response which do not account for this upper layer can be totally inadequate. Link response predictions used here involve a new method of calculation which does take account of the smoke layer environment. Favorable comparisons between predictions and experiment are obtained and experiments for further validation of this method are recommended. Finally, it is found that sprinkler link-to-ceiling spacing can have a significant effect on the thermal response of links and it is recommended that a method which accounts for this effect be developed and validated.

  4. Development of a reliable questionnaire to assist in the diagnosis of fetal alcohol spectrum disorders (FASD)

    2013-01-01

    Background A battery of clinical assessments was used in the Lililwan* Project, Australia’s first population-based Fetal Alcohol Spectrum Disorders (FASD) prevalence study, conducted in the remote Fitzroy Valley, Western Australia. One objective was to develop and assess test-retest reliability of an acceptable questionnaire for collecting health information in remote Aboriginal communities feasible for use in the Lililwan Project. Methods A questionnaire was developed by paediatricians to assist in diagnosis of FASD. Content was based on a literature review of FASD diagnostic criteria, existing questionnaires and risk factors for FASD and birth defects. Aboriginal community members, including qualified Aboriginal language interpreters, adapted the questionnaire to ensure language and cultural components were appropriate for use in the Fitzroy Valley. Locally developed pictorial aids were used for gathering accurate information on alcohol use. Aboriginal ‘community navigators’ assisted researchers to translate the questions into Kimberley Kriol or local Aboriginal languages depending on participant preference. A subset of 14 questions was assessed for test-retest reliability in 30 parents/carers of children in the Lililwan Project cohort, who were interviewed by one rater using the entire questionnaire, then by a second rater who repeated 14 critical questions at least 6 hours later. Results The full questionnaire contained 112 items and took 50 minutes to administer. For a subset of 14 items from the full questionnaire percent exact agreement between raters ranged from 59-100%, and was below 70% for only 1 question. Test-retest reliability was excellent (Kappa 0.81-1.00) for 5 items, substantial (Kappa 0.61-0.80) for 5 items, and moderate, fair or slight (Kappa ?0.60) for the remaining 4 items tested. Test-retest reliability for questions relating to alcohol use in pregnancy was excellent. When questions had moderate, fair or slight agreement, information was obtained from alternate sources e.g. medical records. Qualitative feedback from parents/carers confirmed acceptability of the questionnaire. Conclusions This questionnaire had acceptable test-retest reliability and could be used to collect demographic, socio-cultural and biomedical information relevant to the diagnosis of FASD in Aboriginal communities throughout Australia and elsewhere. Community input is crucial when developing and administering questionnaires for use in cross-cultural contexts. *Lililwan is a Kimberley Kriol word meaning ‘all the little ones’. Kimberley Kriol is the main language spoken by Aboriginal people in the Fitzroy Valley. PMID:23496974

    We developed a 103-item self-reporting questionnaire to assess the burden of primary headache disorders on those affected by them, including headache characteristics, associated disability, co-morbidities, disease-management and quality of life. We validated the questionnaire in five languages with 426 participants (131 in UK, 60 in Italy, 107 in Spain, 83 in Germany/Austria, and 45 in France). After a linguistic and a face-content validation, we tested the questionnaire for comprehensibility, internal consistency and test-retest reliability at an interval of one month. In the different countries, response rates were between 73% and 100%. Test-retest reliability varied between -0.27 to 1.0 depending of the nature of the expected agreement. The internal consistency was between 0.69 and 0.91. The EUROLIGHT questionnaire is suitable for evaluating the burden of primary headache disorders, and can be used in English, German, French, Italian and Spanish. PMID:20713559

    The aim of this work is to examine the pentafactorial validity of the AF5 Self-Concept Questionnaire in Spanish and Chilean young adults. From the responses of a total of 4,383 young adults aged 17 to 22 years (1,918 Spanish, 44%, and 2,465 Chilean, 56%) it was analyzed the reliability of the instrument, the compared validity of the 5 oblique factor model proposed by the authors versus the unifactorial and the orthogonal alternative models, and was studied the invariance of one Chilean sample. The results of confirmatory factor analyses supported the authors' pentafactorial model. The multi-group factorial invariance showed that Chilean sample of the AF5 does not change neither the Spanish factor weights, nor the variances and covariances of the factors, or the error variances of items. Finally, the internal consistency of the five scales was good in the samples of both countries. PMID:22059311

    The aim of this paper is to examine the relationships among nurses' knowledge of, attitudes towards and level of competence in nursing practice, as well as factors influencing nurses' competence in nursing practice, in typhoon disaster relief work. A cross-sectional descriptive study was conducted using a self-developed questionnaire to obtain data from 607 nurses working in four tertiary hospitals and two secondary hospitals in Fujian, China, in November 2011. Our findings show that the nurses' average percentage scores on their responses to questions in the domains of knowledge, attitudes and practice were 66.33%, 68.87% and 67.60%, respectively. The findings demonstrated a significant positive relationship between nurses' attitudes and their practice. Nurses' working unit, prior training in typhoon disaster relief, current position of employment and attitudes were significant predictors of nurses' competence in practice. The results indicate that strategies need to be developed for nurses to improve their knowledge, attitudes and practice. PMID:24219840

    A panel of experts formulated relevant domains of sexual function with a focus on sexual interest and desire. The resulting 10-item scale, the Menopausal Sexual Interest Questionnaire (MSIQ), was examined for reliability (internal consistency and test-retest repeatability), construct validity (concurrent, convergent, and discriminant), sensitivity, and specificity in a clinical trial. A principal components analysis identified three factors (desire, responsiveness, and satisfaction) with eigenvalues > 1. A high degree of internal consistency was observed for each of the three domains. Test-retest repeatability correlation coefficients for domain scores were all highly significant. The MSIQ demonstrated adequate construct validity, with all three domains showing a high degree of sensitivity and with two of the three exhibiting specificity to the effects of treatment.

    Introduction and hypothesis Web-based questionnaires are increasingly employed for clinical research. To investigate whether web-based and paper versions of the Pelvic Floor Distress Inventory-20 (PFDI-20) and Pelvic Floor Impact Questionnaire-7 (PFIQ-7) yield similar results, we compared results obtained with these two modes of administration. Methods Women with pelvic floor disorders completed both versions of these questionnaires. Scores between modes of administration were compared using paired t-test and intraclass correlation coefficient (ICC). Results Among 52 participants, there were no significant differences in scores or scale scores between the web-based and paper questionnaires. The ICC was 0.91 for the PFDI-20 score and 0.81 for the PFIQ-7 score (p<0.001 for each). The web-based format was preferred by 22 participants (53%), 10 (24%) preferred the paper format, and 9 (21%) had no preference. Conclusions The acceptability and score equivalence recommend these web-based questionnaires as an alternative to paper questionnaires for clinical research. Summary Web-based administration of the Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire-7 yields similar results to paper-and-pencil administration and is preferred by patients.

    Areas of high nutrients and low chlorophyll a comprise nearly a third of the world's oceans, including the equatorial Pacific, the Southern Ocean and the Sub-Arctic Pacific. The SOLAS Sea- Air Gas Exchange (SAGE) experiment was conducted in late summer, 2004, off the east coast of the South Island of New Zealand. The objective was to assess the response of phytoplankton in waters with low iron and silicic acid concentrations to iron enrichment. We monitored the quantum yield of photochemistry ( Fv/ Fm) with pulse amplitude modulated fluorometry, chlorophyll a, primary productivity, and taxonomic composition. Measurements of Fv/ Fm indicated that the phytoplankton within the amended patch were relieved from iron stress ( Fv/ Fm approached 0.65). Although there was no significant difference between IN and OUT stations at points during the experiment, the eventual enhancement in chlorophyll a and primary productivity was twofold by the end of the 15-day patch occupation. However, no change in particulate carbon or nitrogen pools was detected. Enhancement in primary productivity and chlorophyll a were approximately equal for all phytoplankton size classes, resulting in a stable phytoplankton size distribution. Initial seed stocks of diatoms were extremely low, <1% of the assemblage based on HPLC pigment analysis, and did not respond to iron enrichment. The most dominant groups before and after iron enrichment were type 8 haptophytes and prasinophytes that were associated with ˜75% of chlorophyll a. Twofold enhancement of biomass estimated by flow cytometry was detected only in eukaryotic picoplankton, likely prasinophytes, type 8 haptophytes and/or pelagophytes. These results suggest that factors other than iron, such as silicic acid, light or physical disturbance limited the phytoplankton assemblage during the SAGE experiment. Furthermore, these results suggest that additional iron supply to the Sub-Antarctic under similar seasonal conditions and seed stock will most likely favor phytoplankton <2 ?m. This implies that any iron-mediated gain of fixed carbon will most likely be remineralized in shallow water rather than sink and be sequestered in the deep ocean.

    Background: Obstructive sleep apnea (OSA) is common among surgical patients. The STOP-Bang questionnaire is a validated screening tool with a high sensitivity. However, its moderate specificity may yield fairly high false positive rate. We hypothesized that the specific combinations of predicting factors in the STOP-Bang questionnaire would improve its specificity. Methods: After research ethics approval, consented patients were asked to complete the STOP-Bang questionnaire and then underwent sleep studies. The predictive performance of the STOP-Bang alternative scoring models was evaluated. Five hundred sixteen patients with complete data on the STOP-Bang questionnaire and polysomnography were reported. Results: When the STOP-Bang score was ? 3 (any 3 positive items), the sensitivity and specificity for identifying moderate-severe OSA was 87% and 31%, respectively. The specificity for any 2 positive items from the 4 STOP questions plus BMI > 35 kg/m2, male gender, or neck circumference > 40 cm for identifying moderate-severe OSA was 85%, 77%, and 79%, respectively. Compared with STOP-Bang score ? 3, the predicted probability for severe OSA of the specific combinations of STOP score ? 2 + male and STOP score ? 2 + BMI increased by 36% and 42%, respectively. For severe OSA, the specific combination of STOP score ? 2 + BMI + male demonstrated a specificity of 97% and 86% increase in predicted probability versus any 4 positive items of STOP-Bang questionnaire. Conclusions: The specific constellations of predictive factors improved the specificity of STOP-Bang questionnaire. For patients with STOP score ? 2, male gender, and BMI > 35 kg/m2 were more predictive than age ? 50 and neck circumference > 40 cm. Citation: Chung F, Yang Y, Brown R, Liao P.

    Background As a disease of motor nervous system (motor neuron disease), amyotrophic lateral sclerosis (ALS) has a great impact on several aspects of quality of life (QoL). 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

    Background Pectus excavatum (PE) is the most common chest wall deformity. The Nuss Questionnaire modified for Adults (NQmA) is a disease-specific health-related quality of life assessment tool for patients with pectus deformities. The aim of this study is to adapt the NQmA into Turkish. Methods Two hundred and sixty-five patients with PE were participated, with an age range of 14 to 29 years. All patients underwent a physical examination and had not undergone corrective surgery. The Turkish version of the NQmA was completed by patients and their parents. Results The content validity index based on expert opinions was 91% for the patient questionnaire and 96% for the parent questionnaire. The Cronbach’s alpha value for the NQmA was found to be 0.805 for the patient questionnaire and 0.800 for the parent questionnaire. Exploratory factor analysis was used to assess construct validity. Two factors explained 51.1% of the total variance in the patient questionnaire (psychosocial: 31.145%, Cronbach’s alpha=0.818; physical: 19.955%, Cronbach’s alpha=0.862). In the parent questionnaire, two factors explained 51.422% of the total variance (psychosocial: 26.097%, Cronbach’s alpha=0.743; physical: 25.325%, Cronbach’s alpha=0.827). Construct validity was confirmed by confirmatory factor analysis. Conclusion The Turkish version of the NQmA was found to be valid and reliable for the assessment of quality of life in patients with PE. PMID:25883894

    Objectives: In developing countries out-of-pocket payments (OOP) are as high as 80% of healthcare spending. Generic medicines can be instrumental in reducing this expenditure. The current study is aimed to explore the knowledge, perception, and attitude of general practitioners towards generic medicines in Karachi, Pakistan. Methods: This exploratory, descriptive study was conducted on a sample of 289 randomly selected general practitioners who were dispensing at their private clinics in Karachi, Pakistan. The questionnaires were distributed and collected by hand. Data was entered to SPSS version 17. Fischer’s exact test was applied to see the association between variables. Results: A total of 206 questionnaires were included in the study. A response rate of 71.3% was achieved. Out of 206 respondents, 139 (67.5%) were male while 67 (32.5%) respondents were female. Close to three quaters of the respondents (n= 148; 71.8%) showed correct knowledge about generic medicines being a ‘copy of the brand name medicines’ and ‘interchangeable with brand name medicines’ (n= 148; 71.8%). In terms of safety, the majority of respondents (n=85; 41.26%) incorrectly understood that the generic medicines are less safe than brand name medicines. The total percentage of correct responses was seen in 53% of the respondents. More than half of the respondents agreed that locally manufactured medicines are of the same effectiveness as brand name medicines (n=114; 55.4%). Male practitioners with practice experience of 11-15 years showed positive perception towards the quality of multinational products. The Majority of respondents believed that their prescribing decision is influenced by medical representatives (n=117; 56.8%). More than three-quarters of the respondents expressed their wish to prescribe low cost medicines in their practice (n=157; 76.2%). More than one third of the respondents expressed their uneasiness to prescribe products from all local manufacturers (n=72; 35%). Conclusion: There were gaps identified in the knowledge of respondents. Although good perception and attitude were noted among the respondents, dissemination of information regarding generic medicines may perhaps strengthen generic prescribing. There is a need to introduce ‘Quality by Design’ concept in local manufacturing units. This, in turn, can inculcate confidence in prescribers towards locally manufactured generic medicines.

    In Japan, many people believe in superstitions or omens. Microsurgery results, however, are scientific and thus considered to be black or white. Even if the operator is a proficient master, the possibility of flap necrosis is inevitable. It can be said that microsurgeons live in a world of uncertainty where "might" rules. How do they prepare themselves for an operation? We administered a questionnaire to front-line Japanese microsurgeons and thereby attempted to examine the mental side of these experts. We constructed a detailed questionnaire regarding several factors, including the annual number of microsurgeries, the consciousness of daily life, the physician before and after the operation, and even concerning superstition, habits for good luck, or other beliefs. We sent the survey to the front-line Japanese microsurgeons in our country by e-mail and 20 replies were returned. Many of the surgeons prepare themselves before the operation, from the day before until just before the operation. These surgeons can be divided into three types: type A, microsurgeons who prepare themselves on a daily basis and do not believe in a charm or a jinx; type B, those who do not prepare themselves especially in daily life, but have some charm or jinx; and type C, surgeons who do not have special daily preparation or belief in a superstition. The type C group included a significant number of experienced microsurgeons. Experienced microsurgeons as leaders or trainers of young microsurgeons tend to be natural and not mystic in daily life and thus tend not to be superstitious. PMID:20703989

    Aim To assess the feasibility of administering Patient Reported Outcomes Measures (PROMs) in patients treated with ablation for cardiac arrhythmias, and to conduct the first stage of development and testing of a new PROM tool. Methods and results A new tool was developed by a multidisciplinary team and tested alongside an adaptation of the patient perception of arrhythmia questionnaire (PPAQ) and EQ-5D-5L in a multicentre retrospective audit involving 791 consecutive cardiac arrhythmia patients treated with catheter ablation at three UK centres over 13 months. Data were recorded in the National Cardiac Rhythm Management Database, part of the National Institute for Cardiovascular Outcomes Research. The response rate was 71.9% (n = 569). Patients reported significant improvements across all outcomes and impacts, with reductions in symptoms of 51.7% (heart racing), 33.9% (fatigue) 31.8% (heart flutters), 43.5% (dizziness), 38.6% (breathlessness), 44.2% (chest pressure), 33.1% (trouble concentrating), 15.9% (headache), 28.3% (neck pressure), and 23.4% (fainting) (P < 0.001). The mean number of social days affected reduced by 7.49 days/month (P < 0.001); mean work/school days affected/month reduced by 6.26 (P < 0.001); mean GP/hospital visits reduced by 1.36 days/month (P < 0.001). The procedure met patient expectations in 72% of responders. Conclusions The high response rate suggests that the use of PROMs in this patient group is feasible, with rates equalling those of the National PROMs Programme. The results showed that patients experienced significant improvements in their quality of life following ablation, while feedback allowed the tools to be improved. Further work is required to validate these tools; however, the findings suggest that PROMs could be useful in the audit of ablation techniques. PMID:24627541

    The Heraklion city (Crete Island, Greece) has been chosen as one of the test-sites for the EU-FP7ASTARTE tsunami project. Heraklion is the biggest city in Crete Isl. and the fourth biggest in Greece with a population of about 120,000 which, however, during the summer vacation period nearly doubles. In the past, Heraklion was hit by strong, destructive tsunamis such as the ones of AD 8 August 1303, 10 October 1650 and 9 July 1956. The first and the third were caused by large tectonic earthquakes associated with the eastern segment of the Hellenic Arc the first and with the back-arc extensional regime the third. The one of 1650 was associated with the eruption of the Columbo submarine volcano in the Santorini volcanic complex. One of the activities scheduled for WP9 of ASTARTE project, which aims at building tsunami resilient societies in Europe, is dedicated to organize questionnaire surveys among the populations of the several ASTARTE test-sites. Although the questionnaire is comprised by more than 50 questions, the central concept is to better understand what people know about tsunamis and if they are ready to cope with risks associated with future tsunami occurrences. In Heraklion the survey was conducted during tourism peak season of July 2014, thus questionnaires were collected by both local people and tourists, thus representing a variety of countries. We attempted to keep balance between males and females, while the age ranged from 15 to 65. Totally, 113 persons were interviewed of which 62 were females and 51 males. From the point of view of origin, 58 out of 113 were local people and residents, 22 were Greek tourists and 29 foreign tourists. Generally, the questionnaire consists of four parts. In the first, people were asked about their relation with the area of Heraklion. In the second part, the questions considered the knowledge that people have on tsunamis as a natural, hazardous phenomenon. More precisely, people were asked questions such as what a tsunami is, if Heraklion could be affected by a tsunami, how a tsunami is generated etc. In the third part of the survey, people were asked questions regarding evacuation practices in case of a tsunami attack. In the last part, personal data, such as nationality, age, education level and more were collected. To analyse the replies received we used the statistical software SPSS. The results are really interesting showing that most people have only a general idea about the phenomenon of tsunamis while they don't feel sure about what to do or to avoid in case of a tsunami. This research is a contribution to the EU-FP7 tsunami research project ASTARTE (Assessment, Strategy And Risk Reduction for Tsunamis in Europe), grant agreement no: 603839, 2013-10-30.

    Introduction: Physiological, anthropometrical and thermal perceptual are the most important factors affecting thermoregulation of men and women in workplaces. The purpose of this study was determining the validity of a questionnaire method for assessing women's heat strain in workplaces. Methods: This cross-sectional study was carried out on 96 healthy women. Data were continuously collected over a period of 3 months (July-September) in 2012. Mean ± (SD) of age was found to be 31.5 ± 7.48 years, of height 1.61 ± 0.05 m, of weight 61.55 ± 10.35 kg, and of body mass index 23.52 ± 3.75 kg/m2 in different workplaces. Heart rate and oral temperature were measured by heart rate monitoring and a medical digital thermometer, respectively. Subjects completed a draft questionnaire about the effective factors in the onset of heat strain. After collecting the questionnaires, the data were analyzed by applying Cronbach’sa calculation, factor analysis method, Pearson correlation and receiver operator characteristic curves using the SPSS 18 software. Results: The value for Cronbach's ? was found to be 0.68. The factor analysis method on items of draft questionnaire extracted three subscale (16 variables) which they explained 63.6% of the variance. According to the results of receiver operator characteristic curve analysis, the cut-off questionnaire score for separating people with heat strain from people with no heat strain was obtained to be 17. Conclusions: The results of this research indicated that this quantitative questionnaire has an acceptable reliability and validity, and a cut-off point. Therefore it could be used in the preliminary screening of heat strain in women in warm workplaces, when other heat stress evaluation methods are not available. PMID:23930180

    Background Psoriatic arthritis (PsA) is chronic seronegative inflammatory arthritis that causes irreversible joint damage. Early recognition of PsA in patients with psoriasis is important for preventing physical disability and deformity. However, diagnosing PsA in a busy dermatology outpatient clinic can be difficult. Objective This study aimed to validate the Psoriatic Arthritis Screening and Evaluation (PASE) questionnaire for the detection of PsA in Korean patients with psoriasis. Methods The PASE questionnaire was prospectively given to 148 patients diagnosed with psoriasis but without a previous diagnosis of PsA. All patients underwent radiologic and laboratory examinations, and a subsequent clinical evaluation by a rheumatologist. Results Eighteen psoriasis patients (12.2%) were diagnosed with PsA according to the Classification Criteria for Psoriatic Arthritis. The PASE questionnaire scores of differed significantly between PsA and non-PsA patients. Receiver operator characteristic analysis showed an area under the curve of 0.82 (95% confidence interval: 0.72, 0.92) for PASE score. A PASE score cut-off of 37 points had a sensitivity of 77.8% and specificity of 82.3% for the diagnosis of PsA. Conclusion The PASE questionnaire is a simple and convenient screening tool for detecting PsA in Korean dermatology clinics. A PASE questionnaire score of 37 points appears to be an appropriate cut-off for screening Korean psoriasis patients.

    OBJECTIVE: to present the cultural adaptation of the questionnaire Costs of caring for children with cancer, offering a valid and reliable tool to assess the economic repercussions of childhood cancer for Brazilian families. METHOD: it is a methodological research with a cross-sectional design. The methodological framework to validate the questionnaire was a combined process that included seven steps: translation to Portuguese; first translated consensus version; evaluation by Expert Committee; consensus on the Expert Committee version; back-translation; consensus of back-translated versions; semantic validation. The study was conducted in two phases: phase one was the translation and back-translations process, with five expert committee members. Phase two was the semantic validation, with 24 participants, who answered an instrument about their impressions of the questionnaire and suggested modifications. RESULTS: in phase one, items were included, excluded, and replaced to make the content equivalent and valid for use with Brazilian context. In phase two, the majority of the participants were mothers, who made suggestions about the relevance and clarity of the items in the questionnaire. CONCLUSIONS: the authors discussed these recommendations and made adaptations, turning the questionnaire into a valid and reliable tool for application. PMID:25296142

    Objective To develop a questionnaire to assess parents' experiences and satisfaction with care during very preterm birth. Design Questionnaire development. Setting Parents whose babies had been cared for at five tertiary neonatal units in England. Population A total of 145 women who gave birth before 32 weeks of gestation, and 85 of their partners. Methods A 30-item questionnaire was developed on the basis of qualitative interviews with parents of very preterm babies, a literature review and discussion with relevant experts. The questionnaire was posted to a second group of parents, and its reliability and validity were explored. Main outcome measures The Preterm Birth Experience and Satisfaction Scale (P-BESS) was correlated with two global questions measuring satisfaction with care during the birth. Internal consistency was measured using Cronbach's ?. Results Parents of 458 babies were invited to take part and 147 (32%) responded. Two women and 22 partners were excluded or ineligible, leaving 145 women and 85 partners. Factor analysis produced three clear dimensions: Staff professionalism and empathy, Information and explanations, and Confidence in staff. The total scale and three subscales showed high reliability. Strong positive correlations were found between the questionnaire scales and the two global questions, indicating convergent validity. For women whose partners were present at the birth, a fourth factor was identified ‘Partner Involvement’. Conclusions The P-BESS appears to be a valid measure of satisfaction with care during very preterm birth. PMID:24953082

    The Learning Disability Screening Questionnaire (LDSQ; McKenzie & Paxton, 2006) was developed as a brief screen for intellectual disability. Although several previous studies have evaluated the LDSQ with respect to its utility as a clinical and research tool, no studies have considered the fairness of the test across males and females. In the current study we, therefore, used a multi-group item response theory approach to assess differential item functioning across gender in a sample of 211 males and 132 females assessed in clinical and forensic settings. Although the test did not show evidence of differential item functioning by gender, it was necessary to exclude one item due to estimation problems and to combine two very highly related items (concerning reading and writing ability) into a single literacy item Thus, in addition to being generally supportive of the utility of the LDSQ, our results also highlight possible areas of weakness in the tool and suggest possible amendments that could be made to test content to improve the test in future revisions.

    Background The Michigan Hand Outcomes Questionnaire (MHQ) has been used to assess a variety of hand and upper extremity injuries and conditions for nearly 15 years. It has been included in several overviews of upper extremity outcomes measures, but it has not been systematically examined regarding its clinimetric properties during field trials. Methods We conducted a review of the MHQ in the English language literature from 1998 through March 2012. Data from clinical studies were abstracted and compiled. Results The MHQ has been used in 58 clinical studies and its clinimetric properties have been analyzed in an additional 18 publications. The MHQ compares favorably with other hand outcomes instruments in the areas of test-retest reliability, validity, and responsiveness. High internal consistency may indicate redundancy within the items in the MHQ. The strength of the MHQ is its multidimensional construct in measuring patient-rated outcomes in symptom, function, aesthetics, and satisfaction. Conclusions The MHQ has been applied across a variety of conditions affecting the hand and upper limb. Its psychometric properties have been tested through field trials in various clinical settings around the world. Level of Evidence Systematic Review; Level II PMID:23629117

    2010-04-01

    We designed a semi-structured questionnaire for the introspective evaluation of inner experience of participants undergoing functional magnetic resonance imaging (fMRI) in the resting state. This resting state questionnaire (ReSQ) consists of 62 items organized by five main types of mental activity: visual mental imagery (IMAG); inner language (LANG), split into two subtypes, inner speech (SPEE) and auditory mental imagery (AUDI); somatosensory awareness (SOMA); inner musical experience (MUSI); and mental manipulation of numbers (NUMB). For IMAG and LANG, additional questions estimated association of such activities with ongoing learning, retrospective memories, or prospective thoughts. Using a 0-100% scale, the participant quantitatively rated the proportion of time spent in each mental activity during the resting state fMRI acquisition. A total of 180 healthy volunteers completed the ReSQ immediately after being scanned with fMRI while at rest. Of these, 66% exhibited dominance of a type of mental activity at rest (IMAG: 35%; LANG: 17%; SOMA: 7%; MUSI: 6%; NUMB: 1%). A majority of participants reported either retrospective memories (82%) or prospective thoughts (78%), with 58% of participants reporting both in at least one type of mental activity. Thoughts related to ongoing learning were low (37% of participants). The present results are consistent with those of previous studies investigating inner experience in a natural environment. In conclusion, we provide a robust and easy-to-implement tool for the exploration of mental activities during rest of healthy participants undergoing fMRI. This tool relies on normative data acquired from a 180-participant sample balanced for sex and handedness. PMID:20003916

    The 2002, 2007, and 2012 complementary medicine questionnaires fielded on the National Health Interview Survey provide the most comprehensive data on complementary medicine available for the United States. They filled the void for large-scale, nationally representative, publicly available datasets on the out-of-pocket costs, prevalence, and reasons for use of complementary medicine in the U.S. Despite their wide use, this is the first article describing the multi-faceted and largely qualitative processes undertaken to develop the surveys.

    OBJECTIVE: to propose a discussion about traces of the derivation of meanings, the subjects' discomfort and resistance when they are called upon to signify a questionnaire on the transfer of the Directly Observed Treatment of Tuberculosis policy, in order to reveal the limitations of closed questionnaires in the subject's interpretation process. METHOD: health professionals from a Primary Health Care Unit in Porto Alegre/RS were interviewed and some excerpts from the interviews were investigated in the light of French Discourse Analysis. RESULTS: resistance, discomfort, slips, silencing and the derivation of meanings were observed in the subjects' interpretation. CONCLUSION: the interpretation process has multiple meanings and varies from subject to subject. The questionnaire, as a prototype of the logically stabilized universe, fails when the purpose is to control the interpretation. Its isolated use in health research can entail inexactness or incompleteness of the collected data. Therefore, its use associated with qualitative research techniques is ideal. PMID:25591094
