Abstract：Objective To investigate urban law enforcement officers’ job stress and mental symptoms, and to explore the relationship among job stress, mental symptoms and psychological capital. Methods Symptom Check List-90(SCL-90), Occupational Stressor Questionnaire (OSQ) and Psychological Capital Questionnaire (PCQ) were used to survey 346 urban law enforcement officers in an urban management bureau in Shenzhen City in October, 2015. Correlation analysis and regression analysis were employed for studying the relationship among psychological capital, job stress and mental symptoms. Results The average score of mental symptoms in the urban law enforcement officers was (119.23±42.13), and the positive detection rate of psychological barrier was 21.4%. Mental symptoms were negatively related to affair psychological capital and interpersonal psychological capital (r=-0.287, P<0.001; r=-0.236, P<0.001), but positively related to job stress (r=0.846, P<0.001). Affair psychological capital and interpersonal psychological capital had significant predictive effects on job stress and mental symptoms(t=-0.510,P<0.001;t=-0.608,P<0.001). Conclusions Psychological capital is closely correlated with job stress and mental symptoms among urban law enforcement officers. The higher psychological capital, the less job stress influence on mental symptoms.
