ABSTRACT
BACKGROUND: This study aimed to identify the characteristics of claimed mental disorders. Because the workers believed the cause of the mental disorders was work-related stress or a specific event, we could identify the major work-related stressor for claimed cases. METHODS: We included claimed cases of occupational mental disorder or suicide reported during 2010–2014 to the Korea Workers Compensation and Welfare Service (KCOMWEL), established by Industrial Accidents Insurance (IACI) Act. We conducted qualitative analysis using a form specifically developed for this study as well as a quantitative analysis. RESULTS: Of the 569 claimed cases, 142 cases were recognized as occupational mental disorder or suicide. The approval rate was 24.9 %. Suicide was the most commonly approved mental disorder (23.0 %), followed by major depressive disorder (14.9 %). Regarding profession, 109 workers were managers, and 95 workers were office clerks. The main work-related stressors of the approved cases were acute stressful events (76 cases), long working hours (12 cases), and changes in workload (6 cases). The primary stressful events were work-related legal problems, workplace violence, and employment status-related issues. CONCLUSION: Claims due to mental disorders or suicide increased during the 5-year study period, and the approval rate was approximately 33 %, and the main stressor of the claimed cases was an acute stressful event such as physiologic trauma, employment-related issues, fear of legal or financial responsibility, abrupt change in organizational responsibility, or workplace violence.
