负性自动思维在海军官兵心理应激程度与心理健康关系中的中介作用

Mediating effect of negative automatic thoughts on relationship between psychological stress and mental health in naval officers and soldiers

目的调查海军官兵心理健康状况及其影响因素,并分析负性自动思维在心理应激程度与心理健康关系中的中介作用。方法采用军人心理应激自评问卷(PSET)、自动思维问卷(ATQ)、症状自评量表(SCL-90)对整体抽取的海军某部队642名官兵进行问卷调查,分析变量间的相互关系。结果回收有效问卷583份,有效率为90.80%。相关分析结果显示,心理应激程度、负性自动思维均与心理健康状况(SCL-90总分)两两正相关(P均<0.05);回归分析结果显示,心理应激程度、负性自动思维能够预测心理健康状况,负性自动思维在心理应激程度与心理健康间的中介效应显著(占总效应的37.30%),且军官、士官和义务兵的心理健康状况差异有统计学意义(P<0.05)。结论心理应激程度和负性自动思维是影响海军官兵心理健康的重要因素,心理应激程度可以直接或间接通过负性自动思维的中介作用影响官兵的心理健康。

Objective To investigate the mental health status of naval officers and soldiers and its influencing factors,and explore the mediating effect of negative automatic thoughts on the relationship between psychological stress and mental health.Methods A total of 642 naval officers and soldiers from a naval force were investigated with the psychological stress self-evaluation test(PSET),the automatic thoughts questionnaire(ATQ)and the symptom checklist 90(SCL-90),and the relationships between the variables were analyzed.Results Altogether 583 valid questionnaires were collected,with an effective rate of 90.80%.Correlation analysis showed that the degree of psychological stress and negative automatic thoughts were positively correlated with mental health(total score of SCL-90)(both P<0.05).Regression analysis showed that the degree of psychological stress and negative automatic thoughts could predict the mental health status;the mediating effect of negative automatic thoughts between the degree of psychological stress and mental health was significant(accounting for 37.30%of the total effect),and there were significant differences in mental health status among officers,sergeants and conscripts(P<0.05).Conclusion The degree of psychological stress and the negative automatic thoughts are important factors affecting the mental health of naval officers and soldiers.The degree of psychological stress can directly or indirectly affect the mental health through the mediating effect of negative automatic thoughts.
