边防官兵心理应激和心理健康的关系:心理资本的中介作用和表达抑制的调节作用

Effect of psychological stress on mental health of frontier officers and soldiers: the mediating role of psychological capital and the moderating role of expressive suppression

目的了解心理应激对边防官兵心理健康的影响和作用机制,探讨心理资本的中介作用以及表达抑制的调节作用。方法2020年2月至6月,采用心理健康自评问卷、心理资本量表、心理应激自评问卷、情绪调节量表对777名边防官兵进行现场问卷调查。结果边防官兵心理健康与心理应激(r=0.625,P<0.01)、表达抑制(r=0.113,P<0.01)显著正相关,与心理资本(r=-0.191,P<0.01)、认知重评(r=-0.085,P<0.01)显著负相关。结构方程模型表明心理资本在心理应激和心理健康间起部分中介作用,表达抑制在心理应激对心理健康的影响路径中发挥调节作用。结论心理应激不仅直接影响边防官兵的心理健康,还通过心理资本间接影响边防官兵的心理健康,且受到表达抑制的调节作用。

Objective To study the influence and mechanism of psychological stress on mental health of frontier officers and soldiers,and to explore the mediating role of psychological capital and the moderating role of expressive suppression.Methods From February to June 2020,777 frontier officers and soldiers were investigated by Self-Reporting Questionnaire 20,Positive Psychological Capital Questionnaire,Psychological Stress Self-Evaluation Test,and Emotion Regulation Questionnaire.Results The mental health of frontier officers and soldiers had a significant positive correlation with psychological stress(r=0.625,P<0.01)and expressive suppression(r=0.113,P<0.01),and a significant negative correlation with psychological capital(r=-0.191,P<0.01)and cognitive reappraisal(r=-0.085,P<0.01).The structural equation model showed that psychological capital played a partial mediating role between psychological stress and mental health,and expressive suppression played a moderating role in the influence path of psychological stress on mental health.Conclusion Psychological stress not only directly affects the mental health of frontier officers and soldiers,but also indirectly affects the mental health of frontier officers and soldiers through psychological capital,and it is moderated by expressive suppression.
