ABSTRACT

OBJECTIVE: To explore the relationship between occupational stress response and psychological symptoms of metro-drivers and the mediating role of neurotic personality. METHODS: A total of 396 metro-drivers in a subway operating company were selected as the research subjects using judgment sampling method. Their psychological symptoms, neurotic personality and occupational stress response were evaluated using the Symptom Checklist 90, the Neurotic Subscales of NEO Five-Factor Inventory, and the Personal Strain Questionnaire of Occupational Stress Inventory Revised Edition. RESULTS: The scores of psychological symptoms, neurotic personality and occupational stress response in the metro-drivers were(148.8±42.7),(29.3±6.3) and(104.2±14.2), respectively. The occupational stress of metro-drivers was positively correlated with the psychological symptoms score(correlation coefficient was 0.45, P<0.01), and neurotic personality was positively correlated with occupational stress response and psychological symptoms scores(correlation coefficients were 0.44 and 0.53 respectively, all P<0.01). The occupational stress response of metro-drivers played a direct effect on their psychological symptoms, and the direct effect was 0.825. Neurotic personality played a partial mediating effect between occupational stress response and psychological symptoms, and the mediating effect was 0.537, accounting for 39.4% of the total effect. CONCLUSION: The neurotic personality of metro-drivers plays a partial mediating role between occupational stress response and psychological symptoms.
