The mediating effect of neurotic personality between occupational stress and psychological symptoms in metro-drivers

目的探讨地铁列车驾驶员职业紧张反应与心理症状的关系以及神经质人格的中介作用。方法采用判断抽样方法,选择某地铁运营公司396名列车驾驶员为研究对象,采用《症状自评量表》、《大五人格问卷》的《神经质分量表》和修订版《职业紧张量表》的《个体紧张反应子问卷》对其心理症状、神经质人格和职业紧张反应进行测评。结果地铁列车驾驶员心理症状、神经质人格、职业紧张反应得分分别为(148.8±42.7)、(29.3±6.3)和(104.2±14.2)分;其职业紧张反应与心理症状得分呈正相关(相关系数为0.45,P<0.01),神经质人格与职业紧张反应、心理症状得分均呈正相关(相关系数分别为0.44、0.53,P值均<0.01)。地铁列车驾驶员职业紧张反应对其心理症状有直接影响作用,直接效应值为0.825;神经质人格在职业紧张反应与心理症状之间具有部分中介作用,中介效应值为0.537,占总效应的39.4%。结论地铁列车驾驶员的神经质人格在职业紧张反应与心理症状之间起部分中介作用。

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.
