The Impact of Perceived Social Support on Mental Health among Workers in Hot Environments: The Mediating Effect of Mental Resilience

摘要: 目的：探讨热环境下作业人员领悟社会支持对心理健康的影响，并探究心理弹性在其中的中介作用。方法：采取方便抽样的方法，使用领悟社会支持量表、一般心理健康问卷和心理弹性量表对执行某热环境作业任务三个月以上的2274名作业人员进行问卷调查。结果：共收回有效问卷2249份，热环境下作业人员的领悟社会支持、心理健康与心理弹性状况总体较好，且受到锻炼习惯的显著影响；领悟社会支持、心理健康与心理弹性三者间两两存在显著相关，领悟社会支持可直接正向预测作业人员的心理健康，也可通过心理弹性的部分中介作用预测作业人员的心理健康，中介效应占比为40.43%。结论：热环境下作业人员的心理弹性在领悟社会支持和心理健康间起部分中介作用。

Abstract: Objective: To explore the influence of perceived social support on mental health of workers in hot environment, and explore the mediating effect of mental resilience. Methods: A convenient sampling method was adopted to investigate 2274 workers who have been executing a hot environment task for more than three months by using the Perceived Social Support Scale, the General Health Questionnaire 12 and the Connor-Davidson Resilience Scale. Results: A total of 2249 valid questionnaires were collected, and the overall understanding of perceived social support, mental health, and mental resilience of workers in hot environments was good, and was influenced by their exercise habits; perceived social support, mental health, and mental resilience are significantly correlated with each other. Perceived social support can directly predict the mental health of workers in hot environments, and can also predict the mental health through the partial mediating effect of mental resilience, with the mediating effect accounting for 40.43%. Conclusion: Mental resilience plays a partial mediating role in the perceived social support and mental health among workers in hot environments.
