| 目的 探究自尊和积极应对方式在心理弹性与疲劳之间的中介作用。方法 整群抽取1 092人作为研究对象，全部为男性，采用多维疲劳量表、心理弹性量表、简易应对方式问卷及罗森伯格自尊量表进行测量。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、积极应对方式及自尊对疲劳的预测性，构建结构方程模型检验积极应对方式、自尊在心理弹性与疲劳之间的中介作用。结果 共回收有效问卷1 065份，有效率为97.53%。Pearson 相关性分析结果表明疲劳与心理弹性、积极应对方式、自尊呈负相关（r＝—0.619、—0.538、—0.589，均P＜0.01），与消极应对方式呈正相关（r＝0.340，P＜0.01）；心理弹性与积极应对方式、自尊呈正相关（r＝0.706、0.583，均P＜0.01）,与消极应对方式无相关性（r＝0.014，P＞0.05）；自尊与消极应对方式呈负相关（r＝—0.181，P＜0.01），与积极应对方式呈正相关（r＝0.474，P＜0.01）。分层线性回归分析结果表明心理弹性可以独立解释疲劳38.3%的方差变异（P＜0.01）， 加入积极应对方式和自尊后可多解释疲劳9.2%方差变异（P＜0.01）。结构方程模型拟合度指标为χ2＝31.404，df＝7，χ2/df＝4.486，比较性配适指标为0.994，塔克-刘易斯指数为0.998，近似误差均方根为0.014；中介效应分析显示积极应对方式（P＝0.01）、自尊（P＜0.001）存在中介效应，且自尊的中介效应大于积极应对方式（P＝0.007），心理弹性的直接效应显著（P＜0.001）。结论 自尊、积极应对方式在心理弹性与疲劳之间存在部分中介效应，且自尊的中介效应更大，提示心理弹性、自尊、积极应对方式是疲劳的保护性因素，可以通过开展心理弹性训练，提升自尊水平，采取积极的应对方式来减少疲劳程度。 |

| Abstract: |
| Objective To investigate the mediation effects of positive coping style and self-esteem on the relationship between mental resilience and fatigue. Methods A total of 1 092 males were selected by cluster sampling, and were surveyed using multidimensional fatigue inventory scale, the Connor-Davidson resilience scale, simplified coping style questionnaire, and Rosenberg self-esteem scale. Pearson correlation analysis was used to explore the relationship between variables, and hierarchical linear regression was used to analyze the predictive value of mental resilience, positive coping style, and self-esteem for fatigue. Structural equation model was constructed to investigate the mediation roles of positive coping style and self-esteem in the relationship between mental resilience and fatigue. Results A total of 1 065 valid questionnaires were collected, with an effective rate of 97.53%. The results of Pearson correlation analysis suggested that fatigue was negatively associated with mental resilience, positive coping style, and self-esteem (r＝—0.619, —0.538, —0.589; all P＜0.01), and positively associated with negative coping style (r＝0.340, P＜0.01); mental resilience was positively correlated with positive coping style and self-esteem (r＝0.706, 0.583; both P＜0.01), but not correlated with negative coping style (r＝0.014, P＞0.05). Self-esteem was negatively correlated with negative coping style (r＝—0.181, P＜0.01), and positively correlated with positive coping style (r＝0.474, P＜0.01). The results of hierarchical linear regression showed that mental resilience could independently explain 38.3% of the variance of fatigue (P＜0.01), and self-esteem and positive coping style could explain an additional 9.2% variance of fatigue (P＜0.01). The model fit index of structural equation model was χ2＝31.404, df＝7, χ2/df＝4.486, with the comparative fit index being 0.994, Tucker-Lewis index being 0.998, and root mean square error of approximation being 0.014. The mediation effect analysis showed that the mediation effects of positive coping style (P＝0.01) and self-esteem (P＜0.001) were significant, with that of self-esteem being greater than that of positive coping style (P＝0.007), and the direct effects of mental resilience was significant (P＜0.001). Conclusion Self-esteem and positive coping style have partial mediation effect on the relationship between mental resilience and fatigue, and the mediation effect of self-esteem is greater, suggesting that mental resilience, self-esteem and positive coping style are protective factors of fatigue. Carrying out resilience training, improving self-esteem, and adopting positive coping style can reduce the fatigue. |
