Relationship between depressive symptoms and perceived individual level occupational stress among Japanese schoolteachers.

Japanese teachers are mentally and physically burdened with various work stressors. This cross-sectional study examined the relationship between depressive symptoms and perceived individual level occupational stress including role problems among Japanese schoolteachers. This study included 1,006 teachers working in public schools in a Japanese city. The Japanese version of Zung's Self-Rating Depression Scale (SDS) was used to evaluate depressive symptoms, and the Generic Job Stress Questionnaire was used to evaluate occupational stress and three measures of social support. Subjects with SDS scores of more than 50 were categorized into the "depressive group." We examined the relationship between depressive symptoms and perceived individual level occupational stress using multiple logistic regression analyses. A total of 202 (20.1%) teachers belonged to the depressive group. We found that high role ambiguity, high role conflict, high quantitative workload, and low social support from family or friends were significantly related to depressive symptoms. To moderate role ambiguity and role conflict experienced by teachers, it is necessary to clarify the priority order of teachers' work. Furthermore, it is necessary to reduce workload by focusing on the content of teachers' work and the setting of education itself. Focusing on these elements will reduce teachers' depressive symptoms.

Relationships between occupational stress and depressive symptoms among prison officers in Japan.

BACKGROUND: The relationships between occupational stress and depressive symptoms in prison officers have rarely been studied in Japan. Thus, we analyzed the associations between occupational stress factors and depressive symptoms among Japanese prison officers. METHODS: This was a cross-sectional study involving 426 male prison officers (20-60-year-old). Depressive symptoms were assessed using the Zung Self-Rating Depression Scale. Using this scale and a cut-off point of 50, the subjects were divided into the "depressive group" and "non-depressive group". Occupational stress was evaluated using the Generic Job Stress Questionnaire. Comparisons among the groups were performed with multiple logistic regression analysis. RESULTS: Of the 426 subjects, 107 were included in the depressive group. After adjusting for demographic and occupational variables, higher scores for the physical environment, role ambiguity, and quantitative workload and a lower score for social support from co-workers were found to be associated with an increased odds ratio of depressive symptoms. CONCLUSIONS: The physical environment, role ambiguity, quantitative workload, and social support from coworkers are associated with depressive symptoms in Japanese prison officers. We hope that educating prison officers about the results of this study and organizational/individual-based improvement strategies will reduce their risk of depression.
