Confirmatory Factor Analysis of the Occupational Stress Inventory-Revised among Shahid Beheshti University Teachers

The main purpose of this study was to examine the factorial validity of the Occupational Stress Inventory-Revised (OSI-R، Osipow، 1998) among male and female university teachers. 285 university teachers (150 male and 135 female)، who were selected through multi-stage random sampling method، completed the Occupational Stress Inventory-Revised (OSI-R، Osipow، 1998). Confirmatory factor analysis was used to examine the factorial validity of OSI-R. The results of confirmatory factor analysis، based on AMOS software، revealed that the tree-factor model of OSI-R consisted of occupational role stress (role overload، role insufficiency، role ambiguity، role boundary، responsibility and physical environment)، coping resources (recreational activities، self-care behaviors، social support systems and rational/cognitive skills) and personal strain (vocational strain، psychological strain، interpersonal strain، physical strain) fit to the data. On the other hand، the results of confirmatory factor analysis indicated that multidimensional model of OSI-R had an acceptable fit to the data among Iranian university teachers. In sum، the results emphasizing the robustness of the OSI-R and its validity to assess occupational stress among Iranian university teachers reveal that the basic structures and causal mechanisms of stressful occupational experiences follow general nomothetic principles.
