| 目的 研究军人疲劳与心理弹性、社会支持及自我效能感的关系。方法 采用多维疲劳量表、心理弹性量表、一般自我效能感量表和中文版社会支持问卷对812名军人进行测试。采用Pearson相关性分析探讨变量间的关系，采用分层线性回归分析心理弹性、社会支持及自我效能感对疲劳的预测性，并通过构建结构方程模型检验社会支持、自我效能感在心理弹性与疲劳之间的中介作用。结果 共回收有效问卷794份，有效率为97.78%。Pearson相关性结果分析表明军人的疲劳与心理弹性、社会支持及自我效能感均呈负相关（r=-0.646、-0.460、-0.520，均P<0.01），心理弹性与社会支持、自我效能感均呈正相关（r=0.458、0.618，均P<0.01），社会支持与自我效能感呈正相关（r=0.423，P<0.01）。分层线性回归分析结果表明心理弹性可独立预测疲劳水平（P<0.01），同时社会支持和自我效能感对疲劳的回归显著（均P<0.01），三者可解释疲劳46.6%的方差变异。结构方程模型结果表明社会支持、自我效能感在心理弹性与疲劳之间的中介作用显著（P<0.001，P=0.026），同时两者的链式中介在心理弹性与疲劳之间的也存在显著中介效应（P<0.001）。结论 加强军人心理弹性水平训练，提高军人社会支持水平和军人自我效能感对增强军人疲劳应对能力、降低疲劳反应、提高作业效能具有重要意义。 |

| Abstract: |
| Objective To explore the relationship among fatigue, mental resilience, social support and self-efficacy in military personnel. Methods A total of 812 military personnel were tested with multidimensional fatigue inventory scale, the Connor-Davidson resilience scale, general self-efficacy scale, and Chinese version social support revalued scale. Pearson correlation analysis was used to explore the relationship between variables, and hierarchical linear regression was used to analyze the predictive effects of mental resilience, social support, and self-efficacy on fatigue. Structural equation model was constructed to investigate the mediation roles of social support and self-efficacy in the relationship between mental resilience and fatigue. Results A total of 794 valid questionnaires were collected, with an effective rate of 97.78%. The results of Pearson correlation analysis suggested that fatigue was negatively associated with mental resilience, social support, and self-efficacy (r=-0.646, -0.460, -0.520, all P<0.01), mental resilience was positively associated with social support and self-efficacy (r=0.458, 0.618, both P<0.01), and social support was positively associated with self-efficacy (r=0.423, P<0.01). Hierarchical linear regression analysis revealed that mental resilience could independently predict fatigue (P<0.01); social support and self-efficacy had a significant regression with fatigue (both P<0.01); and the 3 variables could explain 46.6% variance of fatigue. The results of structural equation model showed that social support and self-efficacy mediated the relationship between mental resilience and fatigue (P<0.001, P=0.026); furthermore, the chain mediation of social support and self-efficacy also played a mediation role in the relationship between mental resilience and fatigue (P<0.001). Conclusion The programs to enhance mental resilience, social support and self-efficacy can provide significant benefit for improving the abilities of military personnel to deal with fatigue and for improving their operational efficiency. |
