A Persian Validation of the Occupational Depression Inventory

Abstract

Abstract: The present study examined the psychometric and structural properties of the Persian version of the Occupational Depression Inventory (ODI). The ODI focuses on depressive symptoms that employed individuals specifically ascribe to their work. A sample of 355 Iranian schoolteachers was surveyed. Exploratory structural equation modeling (ESEM) bifactor analysis indicated that the ODI meets the requirements for essential unidimensionality. ESEM bifactor analysis and scalability analysis supported the use of the ODI’s total score. The instrument exhibited high reliability. Cross-cultural measurement invariance was supported. As for the concurrent validity of the ODI, occupational depression correlated, in the expected direction, with job satisfaction, life satisfaction, well-being, work engagement, sick leave, and antidepressant intake. No association was observed with sex, age, length of employment, and a history of depressive disorders over the past year. The ODI displayed a balance of convergent and discriminant validity vis-a-vis an attribution-free measure of depressive symptoms. The prevalence of occupational depression was estimated at 2.8% in our sample. Our findings endorse the Persian version of the ODI and confirm the instrument’s overall robustness.
