【摘要】 目的 探讨自我效能在老年髋关节置换术后患者的主要照顾者应对方式与照顾负担间的中介效应。方法 采取便利抽样法，选取2022年10月至2023年7月在佛山市某三级甲等中医院行髋关节置换术患者的260名主要照顾者作为研究对象。采用一般自我效能量表、简易应对方式问卷和Zarit照顾负担量表进行调查，运用结构方程模型分析自我效能在应对方式与照顾负担间的中介效应。结果 253名主要照顾者完成研究。其自我效能得分为（27.7±5.6）分，应对方式得分为（33.7±7.7）分，照顾负担得分为（34.4±10.2）分；自我效能得分与积极应对得分呈正相关（r=0.550,P<0.05），与照顾负担得分呈负相关（r=-0.427,P<0.05）；自我效能在应对方式与照顾负担间起完全中介效应。结论 老年髋关节置换术后患者的主要照顾者的自我效能和照顾负担均处于中等水平，应对方式以积极应对为主，自我效能在应对方式和照顾负担间发挥中介效应。更多还原

【Abstract】 Objective To explore the mediating effect of self-efficacy on the relationship between coping styles and care burden among primary caregivers of elderly patients after hip replacement surgery. Methods A convenient sampling method was employed to enrol the primary caregivers of patients who received hip replacement surgery in a Grade ⅢA hospital between October 2022 and July 2023. A total of 260 caregivers were surveyed using the general self-efficacy scale,simple coping style questionnaire and Zarit care burden scale. A structural equation model was used to analyse the mediating effect of self-efficacy on the relationship between coping style and care burden. Results Toally 253 caregivers completed the study. The study had found that the mean self-efficacy among the primary caregivers scored（ 27.7±5.6）,the positive coping score was（ 33.7±7.7）,and the total care burden score was（ 34.4±10.2）. Selfefficacy exhibited a positive correlation with the positive coping styles（ r=0.550,P<0.05） and a negative correlation with the care burden （r=-0.427,P<0.05）. The Bootstrap test revealed that self-efficacy mediated the relationship between coping styles and care burden,with a mediating effect of-0.232（ 95%CI:-0.359,-0.121）,accounting for 47.02 % of the total effect. Conclusion The self-efficacy of primary caregivers is moderate. It predominantly characterised by positive coping strategies. The coping strategies of primary caregivers work through their self-efficacy.更多还原
