Validation and factor structure of the Japanese version of the inventory to diagnose depression, lifetime version for pregnant women.

ABSTRACT:

Introduction

A history of major depressive disorder before pregnancy is one risk factor for peripartum depression. Therefore, the purpose of the present study was to examine the validation and factor structure of the Japanese version of the Inventory to Diagnose Depression, Lifetime version (IDDL) for pregnant women.

Methods

The study participants were 556 pregnant women. Factor analysis was performed to identify the factor structure, construct validity was examined based on the results of the factor analysis, and reliability was examined using Cronbach's ? coefficient.

Results

Based on the results of the factor analysis of the IDDL, a bifactor model composed of a single general dimension along with the following five factors was extracted: (1) depression, anxiety, and irritability (items 1, 2, 8-10, and 19-21); (2) retardation, decreased concentration, indecisiveness, and insomnia (items 4, 11, 12, and 17); (3) decrease in appetite/significant weight loss (items 13 and 14); (4) increase in appetite/significant weight gain (items 15 and 16); and (5) diminished interest, pleasure, and libido (items 5-7). Cronbach's ? coefficients for these five factors were as follows: 0.910, 0.815, 0.780, 0.683, and 0.803, respectively.

Conclusions

The reliability, construct validity, and factor structure of the Japanese version of the IDDL were confirmed in pregnant women.

Project description:BACKGROUND:Beck Depression Inventory (BDI-II) is a widely used valid instrument to assess the severity of depression in clinical and normal settings. To meet the necessity of a standard scale for measuring depression among above 265 million Bangla speaking population around the world, this scale was translated and validated. METHODS:Two translations of BDI-II into Bangla were prepared, and then, two back translations were done by medical and language experts in parallel. Thereafter, sentence revision followed by pretest on 20 respondents was done to finalize the Bangla version of BDI-II (BDI-II BV). Afterward, a cross-sectional, comparative, and descriptive study was conducted to validate the scale by purposive sampling technique consisting of 111 persons (both clinical and normal) in three tertiary-level hospitals in Bangladesh. Everyone was given to fill up BDI-II BV at first. Then, they were given to fill up BDI-II BV (n = 49), Bangla version of Depression Anxiety Stress Scales 21-item (DASS21-BV, n = 47) and BDI-II (n = 25) 3-7 days later. The diagnosis of depressive disorder was made according to DSM-5. Correlation study and factor analysis were completed. RESULTS:The mean age was 28.83(±8.70) years. The male-female ratio was 1:0.82. Correlation of scores for BDI-II BV with the DASS21-BV depression subscale was .920; BDI-II BV with BDI-II was .985 (Cronbach's ? .993; t test not significant) and BDI-II BV applied first and the second time was .960 (Cronbach's ? .979; z test not significant). The interitem correlation for all the items was found highly significant (p < .01). Patients having depressive disorder or episodes had significantly higher BDI-II BV scores than normal (M + SD 30.18 + 10.127 than 8.34 + 5.910; p < .001). Partial confirmatory factor analysis demonstrated two-factor loading comprising Cognitive and Somatic-affective symptoms. CONCLUSIONS:Through the translation and validation process, a validated Bangla version of BDI-II was produced to measure depression and its severity among the Bengali population.

Project description:BackgroundThe Occupational Depression Inventory (ODI) was recently devised to assess depressive symptoms that individuals specifically attribute to their work. One purpose of the ODI is to overcome limitations in current assessments of job-related distress. This study aimed to validate the Swedish version of the ODI.MethodsThe study involved 365 individuals employed in Sweden. In addition to the ODI, the study included the Satisfaction with Life Scale, the Effort-Reward Imbalance Questionnaire, the Demand-Control-Support Questionnaire, the GAD-2, and the PHQ-9. We inquired into the factorial validity, dimensionality, scalability, test-score reliability, criterion validity, convergent validity, discriminant validity, and measurement invariance of the ODI.ResultsExploratory structural equation modeling bifactor analysis indicated that the ODI's Swedish version meets the requirements for essential unidimensionality (e.g., explained common variance = 0.872). Measurement invariance held across sexes, age groups, and occupational categories. The instrument exhibited strong scalability (e.g., H = 0.662). The observed total scores thus accurately ranked respondents on the latent continuum underlying the scale. The ODI's total-score reliability was high (e.g., McDonald's ω = 0.929). Speaking to the instrument's criterion validity, we found occupational depression to correlate, in the expected direction, with various work (e.g., job support) and nonwork (e.g., general anxiety) variables. Occupational depression showed large correlations with effort-reward imbalance (r = 0.613) and demand-control imbalance (r = 0.566) at work. Multiple regression analyses supported these associations further. As expected, we observed both a degree of convergent validity and a degree of discriminant validity when examining the ODI against the PHQ-9, an attribution-free measure of depression.DiscussionThis study indicates that the ODI performs well within the Swedish context, consistent with the findings obtained in other linguistic and geographic contexts. The ODI promises to help researchers, practitioners, and public health decision-makers address job-related distress more effectively.
