This study was conducted to determine the relationship between the job stress levels of 669 subway operators in Seoul after the installation of screen doors and their mental health. Data were collected using a structured questionnaire and via web site. A multiple linear regression analysis was conducted using the SPSS 20.0 statistical program. The total score of job stress turned to be higher than the standard score, and physical environment, job demand, insufficient job autonomy, interpersonal conflict and occupational climate were within the top 50% and organizational system within the top 25%. A correlation analysis revealed that job stress was positively correlated with all sub-domains of mental health. In terms of effects of job stress on mental health, there were significant differences according to job demand, organizational system, lack of reward and occupational climate, with an explanatory power of 36.6%. It is expected that this study can provide foundation for the establishment of organizational measures accustomed to job characteristics to prevent job stress of subway operators and the development and implementation of intervention programs for mental health promotion.
