직무스트레스 영역의 중복과 우울 및 자살사고 사이의 관계

Objective : Several recent studies determined the associations of job stress with depression and suicidal idea, but the association between the number of job stress components and depression remains unclear. In the present study, we investigated the associations of the number of components of job stress with depression and suicidal idea. Methods : We studied 194,226 participants who attended employee health screenings from January to December, 2014, and completely answered all the questionnaires, including the short form of Korean Occupational Stress Scale (KOSS), the Center for Epidemiologic Study-Depression (CES-D) and suicidal idea. The presence of clinical depressive symptoms was defined as a CES-D score of ≥21. The subjects in the highest quartile of each subscale of KOSS were considered as suffering from each component of job stress. Chisquare tests, t-tests and logistic regressions were performed to compare study outcomes between groups. Results : When we included all seven components of job stress, there was no significant association of the number of the components with depressive symptoms, or suicidal idea. However, the prevalence of depressive symptoms and suicidal idea was increased only in three occupational stress subscales including job demand, job insecurity and occupational climate. When we analyzed only these 3 components of job stress, the number of job stress subscales was significantly associated with depressive symptoms and suicidal idea, even after adjustment for sex and age. Conclusion : The number of components of occupational stress was associated with depressive symptoms and suicidal idea, only in the related components.
