摘要: 为保障铁路运输安全,以铁路运输乘务员为研究对象,分析工作压力、唾液皮质醇(又称压力激素)、工作表现稳定性、积极与消极情绪之间的关系。通过文献综述提出假设,压力激素皮质醇通过心智体验到情绪和认知能力的改变,这2条潜在通路影响铁路运输乘务员的工作稳定性;再收集68名乘务员的有效问卷、压力激素皮质醇样本及后续6个月的安全生产工作绩效。结果表明:乘务员在工作中感受到的压力越大、压力激素皮质醇含量越高,其认知能力就越差,体验到越多消极情绪,并且,此后6个月的工作表现越不稳定。压力激素皮质醇与铁路运输乘务员的安全生产行为存在高度相关性。提升乘务员抗压能力,可为企业安全生产打下坚实基础。

Abstract: In order to ensure safety of railway transportation, with train operators as research objects, relationship among their work stress, salivary cortisol (also known as stress hormone), stability of work performance, and positive and negative emotions was analyzed. Firstly, through literature review, a hypothesis was put forward that cortisol could feel changes of emotions and cognitive ability, both of which had potential of influencing operators' stability of work performance. Then, valid questionnaires of 68 objects, their samples of' saliva cortisol and work performance over the next 6 months were collected. The results show that the more stress they feel, the higher level of saliva cortisol they will have together with worse cognitive ability and more negative emotions, and moreover, their performance for the following 6 months will be more unstable. Saliva cortisol is highly correlated with operators' safety behaviors, and improving their pressure resistance ability will lay a solid foundation for safe production of enterprises.

Key words: cortisol, railway transportation, operators, negative emotions, safe production
