Metro driver is the prime person who is responsible for metro operation safety. The mental health of a metro driver is very important for the operation of the subway and requires the driver to keep high mental alertness to monitor the surrounding environment and also handle emergencies under uncertain or dangerous conditions. After a long-term occupational strain, a metro driver is likely to suffer from some mental health problems, such as anxiety and depression, that ultimately threaten the lives of passengers. Therefore, in this study, we focus on the psychological symptoms of metro drivers from the angle of occupational strain and neuroticism. A total of 396 metro drivers from Kunming Rail Transit Operation Co., Ltd. in China were investigated through a questionnaire survey. Symptom Checklist-90 (SCL-90), Personal Strain Questionnaire (PSQ), and NEO-Five-Factor Inventory-Neuroticism Subscale (NEO-FFI-N) were applied to evaluate the psychological symptoms, occupational strain, and neuroticism in metro drivers, respectively. The surveyed data were analyzed by SPSS software. Based on the data, a path structural equation model was established to explore the correlation among occupational strain, psychological symptoms, and neuroticism. The results show that the scores for psychological symptoms and occupational strain are higher than the Chinese adult norm among metro drivers. The occupational strain, neuroticism, and psychological symptoms are all positively correlated in the metro drivers. Occupational stress has a direct influence on the psychological symptom, while neuroticism plays a partial mediation role between occupational strain and psychological symptoms. The results of this study can be applied to optimize the employee selection system and training system for metro operation companies.
地铁司机是地铁运营安全的首要责任人。地铁司机的心理健康对地铁运营至关重要，要求司机保持高度的精神警觉性，以监控周围环境，并在不确定或危险的情况下处理紧急情况。经过长期的职业压力，地铁司机很可能会出现一些心理健康问题，如焦虑和抑郁，这最终会威胁到乘客的生命安全。因此，在本研究中，我们从职业压力和神经质的角度关注地铁司机的心理症状。通过问卷调查对中国昆明轨道交通运营有限公司的396名地铁司机进行了调查。分别应用症状自评量表90（SCL-90）、个人压力问卷（PSQ）和大五人格量表-神经质分量表（NEO-FFI-N）来评估地铁司机的心理症状、职业压力和神经质。调查数据采用SPSS软件进行分析。基于这些数据，建立了路径结构方程模型，以探讨职业压力、心理症状和神经质之间的相关性。结果表明，地铁司机的心理症状得分和职业压力得分高于中国成年人常模。地铁司机的职业压力、神经质和心理症状均呈正相关。职业压力对心理症状有直接影响，而神经质在职业压力和心理症状之间起部分中介作用。本研究结果可应用于优化地铁运营公司的员工选拔系统和培训系统。
