Internal consistency and factor structure of Jenkins Sleep Scale: cross-sectional cohort study among 80 000 adults

ObjectivesTo assess the internal consistency and construct validity of the Finnish translation of the Jenkins Sleep Scale (JSS) in a large healthy working-age population with diverse work characteristics.DesignSurvey-based cross-sectional cohort study.SettingSurvey conducted by an institute of occupational health.ParticipantsEmployees of 10 towns and 6 hospital districts.Primary and secondary outcome measuresThe internal consistency defined by a Cronbach’s alpha. Exploratory and confirmatory factor analyses to evaluate the construct structure of the JSS.ResultsOf 81 136 respondents, 14 890 (18%) were men and 66 246 (82%) were women. Their average age was 52.1 (13.2) years. Of the respondents, 41 823 (52%) were sleeping 7 or less hours per night. The mean JSS total score was 6.4 (4.8) points. The JSS demonstrated high internal consistency with an alpha of 0.80 (lower 95% confidence limit 0.80). Exploratory factor analysis supported a one-factor solution with eigenvalue of 1.94. Confirmatory factor analysis showed that all four items were positively correlated with a single common factor explaining 44%–61% of common factor’s variance.ConclusionsThe Finnish translation of JSS was found to be a unidimensional scale with good internal consistency. As such, the scale may be recommended as a practicable questionnaire when studying sleep difficulties in a healthy working-age population.

Abstract Background Given the limited information on parental health literacy measurements, the study aimed to develop and validate the Chinese Parental Health Literacy Questionnaire for caregivers of children under three years old. Methods We conducted a validity and reliability study through a cross-sectional survey and test-retest analysis respectively between March and April 2017. 807 caregivers of children under three years old were recruited, among which 101 caregivers completed the test-retest assessment with two weeks interval. The reliability was determined by internal consistency, spilt-half reliability and test-retest reliability. The construct validity was assessed by confirmatory factor analysis. Results The 39-question Chinese Parental Health Literacy Questionnaire was shown with high internal consistency (Cronbach’s α=0.89), spilt-half reliability (Spearman-Brown coefficient=0.92) and test-retest reliability (Pearson correlation coefficient=0.82). The confirmatory factor analysis showed that the construct of the questionnaire fitted well with the hypothetical model. The participants’ test scores of the Chinese Parental Health Literacy Questionnaire in a cross-sectional survey were positively associated with caregivers being mothers, more educated, of children with Shanghai Hukou, having only one child in the family, having higher family income. Conclusion The Chinese Parental Health Literacy Questionnaire demonstrated good reliability and validity, which could potentially be used as an effective evaluation instrument to assess parental health literacy.

Abstract Background Patient care ownership (PCO) is an essential component in medical professionalism and is crucial for delivering high-quality care. The 15-item PCO Scale (PCOS) is a validated questionnaire for quantifying PCO in residents; however, no corresponding tool for assessing PCO in Japan exists. This study aimed to develop a Japanese version of the PCOS (J-PCOS) and validate it among Japanese medical trainees. Methods We performed a multicenter cross-sectional survey to test the validity and reliability of the J-PCOS. The study sample was trainees of postgraduate years 1–5 in Japan. The participants completed the J-PCOS questionnaire. Construct validity was assessed through exploratory and confirmatory factor analyses. Internal consistency reliability was examined by calculating Cronbach’s alpha coefficients and inter-item correlations. Results During the survey period, 437 trainees at 48 hospitals completed the questionnaire. Exploratory factor analysis of the J-PCOS extracted four factors: assertiveness, sense of ownership, diligence, and being the “go-to” person. The second factor had not been identified in the original PCOS, which may be related to a unique cultural feature of Japan, namely, a historical code of personal conduct. Confirmatory factor analysis supported this four-factor model, revealing good model fit indices. The analysis results of Cronbach’s alpha coefficients and inter-item correlations indicated adequate internal consistency reliability. Conclusions We developed the J-PCOS and examined its validity and reliability. This tool can be used in studies on postgraduate medical education. Further studies should confirm its robustness and usefulness for improving PCO.

The current study was a cross-sectional research and aimed to investigate the factor structure, internal consistency, and validities of the Persian version of the Teasing Questionnaire-Revised (TQ-R). Forward and backward translations of the TQ-R were performed; face and content validities were determined based on comments by a sample of psychology students and specialists. Using the cluster sampling method, 290 participants were recruited, and 201 valid data (Mage = 23.53, SD = 3.53, 64.2% men) were analyzed. The factor structure was assessed by confirmatory and exploratory factor analysis (EFA). The result of the confirmatory factor analysis(es) did not confirm the proposed three, four, and five-factor models. EFA revealed four factors with 23 items, explaining 52.03% of the total variance. The internal consistency of the Persian version of Teasing Questionnaire 23 was in the excellent range (α = 0.92), and its expected associations with external correlates (e.g., depression and anxiety) supported the measure’s convergent validity. The findings indicated that the Persian version of the TQ-R has sound psychometric properties and can be used as a valid and reliable tool in research and clinical outcomes.

OBJECTIVE: Investigate the structural coherency of the 60-item version of the General Health Questionnaire via exploratory and confirmatory factor analyses. METHOD: The study design is a cross-sectional survey. A random sample of 146 individuals from the city of Divinópolis-MG volunteered to participate in the present study and responded to the 60-item version of the General Health Questionnaire adapted and validated for use in Brazil. Statistics consisted of exploratory and confirmatory factor analysis. Reliability was estimated using Cronbach's alpha method. RESULTS: Alpha coefficients for all five content scales of the General Health Questionnaire were high (α > 0.8). For four of the five scales, a unifactorial model of constituent items provided a good fit to the data. Items comprising the fifth scale, Psychic Stress, exhibited a two-correlated factor structure. A factor analysis of scores for the five scales yielded strong evidence of coherency, with all scales loading substantially on a single common factor. CONCLUSION: The General Health Questionnaire shows good psychometric coherency as evidenced by high internal consistency and unidimensionality of all but one of its constituent scales, and uniformly high loadings of all scales on a single overarching factor. These results are consistent with prior findings from the General Health Questionnaire developmental study and Brazilian adaptation studies.

Abstract Background: Self-management is the most important component in the treatment of chronic diseases, including multiple sclerosis (MS). The Bishop and Frain Multiple Sclerosis Self-Management Scale–Revised (MSSM-R) is one of the valid tools available for self-management assessment. The purpose of this study was to evaluate the psychometric properties of the MSSM-R in Iranian people with MS. Methods: This cross-sectional study was conducted in 2018 in the 1600 people with MS in Guilan Province, Iran. In this study, 250 people were selected by convenience sampling. The reliability of the Persian version of this scale was examined by internal consistency and test-retest methods, and validity evidence was evaluated using confirmatory factor analysis. Results: The MSSM-R had acceptable face and content validity. Confirmatory factor analysis results showed that 24 items on this scale have factor loadings in five subscales. Other results showed the internal consistency, as measured by Cronbach α and test-retest reliability, for the MSSM-R overall (α = 0.85, r = 0.77) and for the following subscales: Healthcare Provider Relationship and Communication (α = 0.83, r = 0.70), Treatment Adherence/Barriers (α = 0.70, r = 0.71), Social/Family Support (α = 0.79, r = 0.85), MS Knowledge and Information (α = 0.89, r = 0.72), and Health Maintenance Behavior (α = 0.77, r = 0.75). Conclusions: This study provides evidence of the validity and reliability of the MSSM-R. To further ensure its psychometric properties, additional studies with this scale are suggested.

Weight Stigmatization

The present study was intended to develop a scale to measure perceived weight stigmatization among people with obesity. The study was conducted in five steps. In first step, three focus group discussions were conducted with female obese university students to get the first-hand information related to weight stigmatization. Step two involved four interviews which were conducted with male obese university students to collect detailed information about weight stigmatization experiences of men. Step three included content analysis of qualitative data for item generation. In step four, judge’s opinion was taken, and a committee approach was carried out to select the items for the initial form of the scale. Items for final form of the scale were selected through exploratory factor analysis and confirmatory factor analysis in step five. For exploratory factor analysis, 150 university students (men = 61, women = 89) were included in the sample, whereas, for confirmatory factor analysis, another group of students (men = 78, women = 72) participated in the study. Principal Component Factor Analysis revealed three meaningful structures including Self-Perception, Perceived Social Rejection, and Perceived Impact containing 43 items. Confirmatory factor analysis confirmed this factor structure and all 43 items possessed factor loadings greater than .40. Moreover, results indicated that perceived weight stigmatization had high internal consistency (Cronbach’s alpha = .96) with three subscales having internal consistency .95, .83, and .92 respectively. Therefore, Perceived Weight Stigmatization Scale turned out to be a reliable and valid instrument for measuring perception of weight stigma in adults with obesity.

Abstract Background The Lederman Prenatal Self-Evaluation Questionnaire (PSEQ) is used to assess psychosocial adaptation to pregnancy, labor, childbirth, and maternity. The PSEQ is a tool used in various countries and has been translated into Portuguese; however, it needs to be validated in Brazil. This study aimed to analyze the validity and reliability of the PSEQ in Brazilian pregnant women. Method This methodological validity study investigated internal consistency and reliability using Cronbach’s alpha and intraclass correlation coefficients. Construct validity was assessed using Pearson’s correlation between domains and confirmatory factor analysis. To assess concurrent validity, Pearson’s correlation between the different domains of the PSEQ and Prenatal Psychosocial Profile-Portuguese Version (PPP-VP) was determined. The level of significance was set at 5%. Results This study included 399 pregnant women in the northeastern region of Brazil. The internal consistency and reliability of the total PSEQ score were high (Cronbach's alpha = 0.89; intraclass correlation coefficient = 0.95). Validity analysis showed positive and significant correlations between all PSEQ domains, ranging from 0.14 to 0.56. Confirmatory factor analysis demonstrated the following values of goodness of fit: RMSEA = 0.05, SRMR = 0.08, CFI = 0.61, χ2/df = 1.77. The discriminant and concurrent validities of the PSEQ were confirmed. Conclusions The Portuguese version of the PSEQ has adequate psychometric properties and is a valid and reliable tool to evaluate psychosocial adaptation to pregnancy in Brazilian pregnant women.
