Assessment of the Psychometric Properties of the Holland Sleep Disorders Questionnaire in the Iranian Population.

ABSTRACT:

Background

Assessing sleep disorders and understanding their causes are essential for the proper treatment and management of the disorders. The Holland Sleep Disorders Questionnaire (HSDQ) is a self-assessment questionnaire that measures sleep problems and symptoms based on the six categories of sleep disorders described in the International Classification of Sleep Disorders-2 (ICSD-2). The aim of this study was at validating and assessing the psychometric properties of the HSDQ in Iranian adults.

Method

The study was carried out as a methodological and validation work. The guidelines for translation and cultural adaptation of patient-reported outcome measures were followed for the translation and the cultural validation of the tool. To examine construct validity, exploratory factor analysis (EFA) with 216 participants and confirmatory factor analysis (CFA) with 355 participants were used. As to the reliability, the test-retest method and, as to internal consistency, Cronbach's alpha were employed. Data analyses were done in SPSS-25 and LISREL-8.

Results

The CFA and EFA results confirmed the tool with six factors and 31 items. The R ² index of the model was 0.99, which indicated that 99% of changes in the dependent variable (adults' sleep problem) were attributed to the independent variable (the 31 items). In other words, 0.99 of the changes in the dependent variable were due to the independent variables. The main indices of CFA (χ ²/DF = 2.65, CFI = 0.91NNFI/TLI = 0.92GFI = 0.81, REMSEA = 0.043, R ² = 0.99) were acceptable. In addition, a correlation coefficient below 0.05 was considered as significant. Reliability of the tool based on internal correlation (Cronbach's alpha) was in the 0.701-0.924 range for the subscales and equal to 0.789 for the whole tool.

Conclusion

In general, the results showed that the Farsi version of HSDQ (six factors and 31 items) had acceptable and applicable indices and it can be used as a valid tool in the Iranian society. The tool can be used as a reliable tool in different fields of medical sciences.

Project description:BackgroundUniversities are in charge of training, educating, and preparing students for their future. Teaching and learning methods have a profound role in fulfilling this responsibility by universities. Examining teaching-learning experiences needs a proper tool to collect the information needed. The aim of this study was to collect validity evidence of the modified experiences of teaching-learning questionnaire (ETLQ) in Iranian nursing students.MethodsThe validation process was started by securing the required permissions from the designer of the tool. Then the tool was translated into Farsi using forward-backward method. After preparing a Farsi version of the tool, the content, response process, and internal structure assessment were checked and supported using qualified methods. To examine internal structure, Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted for three sections of the scale with the participation of 278 nursing students. To examine the reliability of the tool, test-retest method was used and internal correlation was examined using Cronbach's alpha.ResultsThe EFA and CFA results confirmed the tool with three domains, seven factors and 33 items. The R2-index of the model was obtained equal to 0.99, which indicates that 99% of the changes in teaching-learning experiences are explained by the tool (33 items). The main indices in CFA were higher than 0.9, which indicates the goodness of fit of the model. Pearson correlation between the items and the subscales was significantly and directly related to the whole scale. Moreover, with Cronbach's alpha equal to 0.944 and test-retest result equal to 0.88, reliability of the Farsi version of modified ETLQ was supported.ConclusionThe results showed that the Farsi version of modified ETLQ had acceptable and applied indices to measure teaching-learning experiences in nursing students. The tool can be used as a valid tool in different fields of education in medical sciences.

Project description:BACKGROUND:Assessing quality of life (QOL) in elderly needs specific instruments. The Older People's Quality of Life Questionnaire (OPQOL-35) is one of the common tools that used for measuring quality of life in elderly populations. The questionnaires contains 35 items tapping into eight domains including life overall, health, social relationships and participation, independence, control over life and freedom, home and neighborhood, psychological and emotional well-being, financial circumstances, culture and religion. This study aimed to translate and validate the OPQOL-35 in Iran. METHODS:Forward-backward procedure was applied to translate the original questionnaire from English into Persian. Then following qualitative face and content validity, a sample of elderly people completed the questionnaire. In order to evaluate the construct validity, exploratory and confirmatory factor analyses was performed. Subsequently, convergent and divergent validity of the factors were evaluated. Reliability was evaluated by performing internal consistency analysis and Intraclass Correlation Coefficients (ICC). RESULTS:In all 500 older people completed the questionnaire. The mean age of participant was 68.92 (SD?=?6.97) years, and mostly were males (66.6%). The result of exploratory factor analysis showed 8 factors with Eigen values of greater than one, which explained 67.4% of the variance observed. Confirmatory factor analysis showed acceptable fit indexes for the data [Comparative Fit Index (CFI)?=?0.92, Minimum Discrepancy Function by Degrees of Freedom divided (CMIN/DF)?=?2.832, Root Mean Square Error of Approximation (RMSEA)?=?0.067]. The convergent and divergent validity did not support three latent factors (Life overall, Independence, control over life, freedom and Psychological and emotional well-being). Convergent and divergent validity shown that construct fulfilled for the health, social relationships and participation, home and neighborhood, financial circumstances, culture and religion latent factors, however the results did not support the convergent and divergent validity for three latent factors (Life overall, Independence, control over life, freedom and Psychological and emotional well-being). Cronbach's alpha coefficient for the subscales ranged from 0.65-0.95. Test-retest reliability (ICC) of the questionnaire with two weeks interval were ranged from 0.88-0.95 indicating a good range of reliability. CONCLUSION:The findings suggest that the Iranian version of OPQOL-35 is a valid measure for assessing quality of life in elderly populations in different settings.

Project description:ObjectiveThe sleep of healthcare students is worth discovering. Mental health and self-rated health are thought to be associated with sleep quality. As such, valid instruments to assess sleep quality in healthcare students are crucial and irreplaceable. This study aimed to investigate the measurement properties of the Sleep Quality Questionnaire (SQQ) for Chinese healthcare students.MethodsTwo longitudinal assessments were undertaken among healthcare students, with a total of 595, between December 2020 and January 2021. Measures include the Chinese version of the SQQ, Patient Health Questionnaire-4 (PHQ-4), Self-Rated Health Questionnaire (SRHQ), and sociodemographic questionnaire. Structural validity through confirmatory factor analysis (CFA) was conducted to examine factor structure of the SQQ. T-tests and ANOVAs were used to examine sociodemographic differences in sleep quality scores. Multi Group CFA and longitudinal CFA were respectively used to assess cross-sectional invariance and longitudinal invariance across two-time interval, i.e., cross-cultural validity. Construct validity, internal consistency, and test-retest reliability were correspondingly examined via Spearman correlation, Cronbach's alpha and McDonald's omega, and intraclass correlation coefficient. Multiple linear regression analysis was performed to examine incremental validity of the SQQ based on the PHQ-4 and SRHQ as indicators of the criterion variables.ResultsCFA results suggested that the two-factor model of the SQQ-9 (item 2 excluded) had the best fit. The SQQ-9 scores differed significantly by age, grade, academic stage, hobby, stress coping strategy, anxiety, depression, and self-rated health subgroups. Measurement invariance was supported in terms of aforesaid subgroups and across two time intervals. In correlation and regression analyses, anxiety, depression, and self-rated health were moderately strong predictors of sleep quality. The SQQ-9 had good internal consistency and test-retest reliability.ConclusionGood measurement properties suggest that the SQQ is a promising and practical measurement instrument for assessing sleep quality of Chinese healthcare students.
