Test-retest reliability of the questionnaire on the screening of sleep disorders

Sleep is a vital component for maintaining good physical and mental health. When sleep is disordered, it can adversely affect an individual's mental and physical wellbeing. Although a variety of single specific disorder measurements are available for specialized clinicians use across the globe, to date, there are no proper screening instruments available for screening multiple sleep disorders at the primary care level. The purpose of this study is to determine the test-retest reliability of the sleep disorder screening questionnaire (SDSQ) for detecting multiple sleep disorders among the Mongolian population. A total of 366 university students were recruited for participation. SDSQ was administrated to all participants on two occasions two weeks apart. The test-retest reliability intra-class correlation (ICC) and Cronbach's alpha of the SDSQ were calculated. The sample consisted of 194 (53%) females, and 172 (47%) males, with a mean age of 21.6. Observed test-retest reliability was ranged from 0.53 to 0.81. The SDSQ was found to have excellent internal consistency with an alpha=0.950. The external validity of SDSQ revealed strong test-retest reliability in the current study population. The discriminant and convergent validity studies are required for the further improvement of the construct of the SDSQ.

Validation of a brief sex addiction screening instrument (PATHOS) and prediction of sex addiction in the Iranian population.

IntroductionSex addiction is a major psychiatric disorder in which a person is compelled to participate in sexual activities despite negative consequences. This study was conducted to localize a brief sex addiction screening instrument (PATHOS) for use in the Iranian population and to determine variables predictive of sex addiction in the general Iranian population.MethodsIn this study, we evaluated the psychometric properties of PATHOS in a sample of 443 Iranians in 2018. Data were analyzed using exploratory factor analysis (Factor 10.8.04 software). Simple and multiple linear regression analyses were used to investigate construct validity and variables predictive of addiction.ResultsExploratory factor analysis identified two factors in this dichotomous questionnaire and reported the questionnaire’s test-retest reliability in the target population. Prognostic variables for sexual addiction in the Iranian population were determined to be female gender, higher education, viewing pornographic videos, having multiple sex partners, having difficulty interacting in sex, and history of masturbation.ConclusionThe Persian version of the brief sex addiction screening instrument (PATHOS) has sufficient reliability and validity in the Iranian population. The predictive variables of sex addiction are indicative of the presence of risk of this disorder in Iranian samples and more studies are needed in order to enable prevention and treatment.

Musicians' Hearing Handicap Index: A New Questionnaire to Assess the Impact of Hearing Impairment in Musicians and Other Music Professionals.

Purpose We aimed to develop and validate the Musicians' Hearing Handicap Index (MHHI), a new self-evaluation tool for quantifying occupation-related auditory difficulties in music professionals. Although pure-tone audiometry is often considered the "gold standard" and is usually employed as the main instrument for hearing assessment, it cannot fully describe the impact of hearing dysfunction. The MHHI is an attempt to complement the hearing impairment assessment toolbox and is based on a unique approach to quantify the effects of hearing-related symptoms or hearing loss on the performance of musicians and other music industry professionals. Method An initial set of 143 questionnaire items was successively refined through a series of critical appraisals, modifications, and suggestions. This yielded an intermediate questionnaire consisting of 43 items, which was administered to 204 musicians and sound engineers. After exploratory factor analysis, the final form of the MHHI questionnaire was obtained, consisting of 29 items. The questionnaire's test-retest reliability, internal consistency, discriminating power, content validity, criterion validity, and aspects of construct validity and inherent conceptual structure were assessed. Results Exploratory factor analysis revealed a combination of four common factors for the 29 validated questionnaire items. They were named "impact on social and working lives," "difficulties in performance and sound perception," "communication difficulties," and "emotional distress." The MHHI was shown to be a valid and reliable instrument to assess musicians' and sound engineers' occupational difficulties due to hearing impairment and related symptoms. Conclusion The ability of the MHHI to discriminate between groups of music professionals with different auditory symptoms or pure-tone audiometry thresholds suggests that auditory symptoms might influence a professional's performance to an extent that cannot be assessed by a pure-tone audiogram.

Validation d'un questionnaire auto-administré sur les valeurs en politique publique de santé.

The aims of this article are to describe the development of a self-administered questionnaire assessing the core values in the field of public health ( radardesvaleurs.com ) and to report the results of a study testing the questionnaire's test-retest reliability, internal consistency and construct validity. A 24-item questionnaire grounded in the conceptual framework of Shalom H. Schwartz (2000) was developed by a group of international experts in public health. Six scores were generated, each linked to a specific value and put on three axes: individualism-equity, autonomy-conformity and risk-security. The questionnaire was submitted to students attending the School of Public Health of the Université de Montréal (ESPUM) (n = 700). A total of 401 students completed the questionnaire, 52 of whom completed it again onemonth later. For the test-retest reliability, all percentages of agreement were equal or superior to 60% except for a single question (50%). All Cohen's kappa coefficients of individual items were strong (> 0.60) except for three questions which presented a very high percentage of agreement. The Intraclass Correlation coefficients of the values' scores varied between 0.27 and 0.77. The three axes' internal consistency was estimated by Cronbach's alphas (between 0.46 and 0.74). The exploratory factorial analysis only partially confirmed the questionnaire's theoretical structure. Despite the limits of the results, the questionnaire has an interesting level of reliability and validity, which makes its pedagogical use pertinent to pursue. The limitation to four items/value, as well as the representativeness of the sampling (ESPUM students), could explain certain empirical shortcomings of the questionnaire.

Test-retest reliability of the questionnaire in the Sasang constitutional analysis tool (SCAT)

BackgroundThe Sasang constitutional analysis tool (SCAT) is an integrated Sasang constitutional analysis system developed by the Korea Institute of Oriental Medicine. This study aimed to evaluate the reliability of a questionnaire for measuring personality and pathophysiological symptoms that is one of the components of the SCAT. MethodsIn this study, data were collected from university students in their twenties. Tests were administered twice, with an interval of 4 weeks between tests. Test-retest data from 176 students were collected and used for analysis. Internal consistency reliability was analyzed by using Cronbach's alpha coefficient, and test-retest reliability was analyzed by using Spearman's rank correlation coefficient. ResultsCronbach's alpha coefficient was 0.788 for personality, 0.511 for eating habits, 0.718 for digestion, 0.667 for heat- or cold-wise penchant, and 0.612 for water ingestion. Spearman's rank correlation coefficients, which were used to assess correlations between test and retest results, ranged from 0.444 to 0.828. ConclusionThe internal consistency and test-retest reliability of the SCAT questionnaire were found to be satisfactory.

Test-retest reliability of Nordic Musculoskeletal Questionnaire in nurses

To evaluate the test-retest reliability of Nordic Musculoskeletal Questionnaire in nurses and to provide supplementary data for evaluating the reliability of the questionnaire in different occupational populations. Nordic Musculoskeletal Questionnaire was translated into Chinese according to the Guidelines for the process of cross-cultural adaptation of self-report measures. We carried out a study to examine the reliability of Chinese-version Nordic Questionnaire among Chinese nurses. This study was conducted in 120 nurses recruited from our hospital, who underwent questionnaire survey twice within one week. The test-retest reliability of questionnaire was analyzed. The Chinese-version Nordic Questionnaire showed a high test-retest reliability, with a Kappa coefficient of 0.72∼1.00. The Chinese-version Nordic Questionnaire has a high test-retest reliability in nurses, so it can be used for the screening and epidemiological investigation of musculoskeletal disorders in this population.

The Surgical Satisfaction Questionnaire (SSQ-8): A Validated Tool for Assessment of Patient Satisfaction Following Surgery To Correct Prolapse and/or Incontinence

To develop a validated questionnaire to assess patient satisfaction following surgery to correct urinary incontinence and/or pelvic organ prolapse. Existing surgical satisfaction surveys focus on the physician or facility rather than the surgical outcome itself. Many times patient satisfaction does not correlate with objective surgical outcomes, or even subjective symptom reporting. There are currently no surgical satisfaction assessment tools designed for any type of surgery, specifically pelvic reconstructive surgery. The process and results of validating a post surgical patient satisfaction questionnaire. A private urogynecology practice in Pennsylvania. 400 women underwent surgery to correct stress urinary incontinence and/or pelvic organ prolapse, each completed the SSQ-8 at 4 months and 1 year. A separate group of 157 women completed the SSQ-8 and an office based satisfaction survey developed by Press Ganey. The lead author developed 12 questions that seemed directly relevant to surgical satisfaction. Face validity was further established by a group of 8 Urogynecologists and 4 Urogynecology nurses who honed it to 8 likert scale questions deemed relevant and non-redundant. Test-retest reliability was assessed by administering the survey to patients at 4 months and 1 year post-op. External validity was assessed by administering a well-established Press Ganey survey designed for medical practices to patients that had also completed the SSQ-8. The questionnaire's test-retest reliability was .80 p<.0001, assuring predictability between the 2 test intervals. The internal consistency reliability, based on Cronbach's alpha was .79. The Bonferroni-adjusted p-value < .02 denoted statistical significance due to the multiple comparisons. The association between SSQ-8 and medical practice survey summary scores revealed a moderate and statistically significant positive correlation (r=.28, p=.004). This questionnaire (SSQ-8) is a valid and reliable tool to measure patient satisfaction after pelvic surgery.

Musculoskeletal pain in obese adolescents

To determine the prevalence of pain, musculoskeletal syndromes, orthopedic disorders and using computers and playing videogames among obese adolescents. This was a cross-sectional study that investigated 100 consecutive obese adolescents and 100 healthy-weight controls using a confidential, self-report questionnaire covering demographic data, sports participation, painful musculoskeletal system symptoms and using computers and playing videogames. The questionnaire's test-retest reliability was tested. Physical examination covered six musculoskeletal syndromes and seven orthopedic disorders. The kappa index for test-retest was 0.724. Pain and musculoskeletal syndromes were equally prevalent in both groups (44 vs. 56%, p = 0.09; 12 vs. 16%, p = 0.541; respectively). Notwithstanding, orthopedic disorders (98 vs. 76%, p = 0.0001), tight quadriceps (89 vs. 44%, p = 0.0001) and genu valgum (87 vs. 24%, p = 0.0001) were significantly more prevalent in obese adolescents than in controls. Median time spent using a computer the day before, on Saturdays and on Sundays were all lower among the obese subjects (30 vs. 60 minutes, p = 0.0001; 1 vs. 60 minutes, p = 0.001; and 0 vs. 30 minutes, p = 0.02; respectively). Obese adolescents were less likely to play handheld videogames (2 vs. 11%, p = 0.003) and there was no difference in the two groups' use of full-sized videogames (p > 0.05). Comparing obese adolescents with pain to those free from pain revealed that pain was more frequent among females (59 vs. 39%, p = 0.048) and was associated with greater median time spent playing on Sundays [0 (0-720) vs. 0 (0-240) minutes, p = 0.028]. Obesity can cause osteoarticular system damage at the start of adolescence, particularly to the lower limbs. Programs developed specifically for obese female adolescents with musculoskeletal pain are needed.

Controlling for occasion-specific effects when assessing the test–retest reliability of self-report health questionnaires

This study proposes a method for self-report health questionnaires to adjust test-retest reliability for changes during the test-retest interval based on an external measure, and to distinguish such changes from random response errors. In our application, eighty participants completed the Symptoms of Illness Checklist (SIC) on two occasions, two weeks apart, immediately before interviews given on each occasion by one of two physicians in a crossover design. The physician interview scores served as external measures, and structural equation modeling was used to estimate the parameters of a model that corrected for the occasion-specific effect of participants' responses using information from the interviews. Correcting for changes in symptoms during the test-retest interval increased SIC test-retest reliability from .744 to .804 and significantly improved model fit (chi2(diff)(1) = 30.78, p < .001). The results suggest methods that can improve the evaluation of self-report health questionnaire test-retest reliability by identifying changes using an external measure, and distinguishing these from random response errors; these increased the estimated SIC test-retest reliability and indicated that the SIC was indeed able to measure changes over the studied time interval. This method can be applied across a broad range of questionnaires.

Questionnaire test- retest reliability

In a clinical follow-up case series study, the test-retest reliability of an outcome measure questionnaire was tested. The study group consisted of 48 patients who had taken part in a vocational rehabilitation programme. Test-retest reliability of a questionnaire was evaluated with the reliability index two years after entering the programme. It was found that the test-retest reliability of demographic data was rather good, although the questions concerning basic and occupational training showed instability over time. The answers concerning general health symptoms, mental working capacity and perceived changes in life during the past 12 months showed particularly high variability. The respondents' opinions on their general outlook of life seemed rather stable. Opinions about the perceived benefits from the intervention were marginally stable. The respondents' opinions about the benefits perceived from the physicians' work were more stable than the opinions about the perceived help from the other members of the rehabilitative team. It was concluded that an outcome analysis questionnaire is a useful tool to document the respondents' general and present perception of life and their present health situation as well as the rehabilitation process. The further development of generally applicable outcome measures for health promotion programmes will require unified, long-term efforts.

The development and validation of a Spanish version of the quality of life in depression scale (QLDS)

Objective: The adaptation of the Quality of Life in Depression Scale, the QLDS, into Spanish. Methods: The original UK version of the QLDS was considered by two translation panels, who produced a Spanish translation. Priority was given to conceptual rather than semantic equivalence. This version was then field-tested with 15 depressed patients. The final stage of the research involved a postal survey of 62 patients, who were asked to complete the measure on two occasions. Results: The Spanish QLDS was found to be appropriate and acceptable by depressed patients. The questionnaire's test-retest reliability and internal consistency were both high, and QLDS scores correlated as predicted with scores on sections of the Nottingham Health Profile. The measure was sensitive to different levels of depression as assessed by the Hospital Anxiety and Depression Scale. Conclusion: The Spanish version of the QLDS is suitable for use in clinical trials and for monitoring individual patients in routine clinical practice.

Test-retest reliability of an upper-extremity discomfort questionnaire in an industrial population.

Efforts to understand or to monitor upper-extremity musculoskeletal disorders among workers have usually involved the use of questionnaires. The goal of this study was to assess the test-retest reliability of an upper-extremity discomfort questionnaire among industrial workers. Test-retest agreement among 148 workers was analyzed using the kappa coefficient for categorical outcomes. Values of kappa greater than 0.75 are considered excellent, values between 0.40 and 0.75 are fair to good, and values of less than 0.40 represent poor agreement beyond chance alone. Test-retest results of continuous measures (eg, visual analogue scale responses) were compared with paired t-tests. The test-retest reliability of the questionnaire used to elicit demographic information, medical history, exercise participation, and information on musculoskeletal symptoms among industrial workers appears to be good to excellent in most instances. These results suggest that most results of this discomfort questionnaire are reliable and suitable for use in epidemiologic studies. For reassurance of the robustness of these findings, similar studies should be carried out in other worker populations with this, and other, questionnaire instruments.
