【摘要】 目的 探讨老年人一般自我效能感和社会参与在身体功能和生理复原力(physical resilience, PR)间的中介作用。方法于2024年3—11月采用整群抽样法，使用简易体能测试量表、生理复原力量表、一般自我效能感量表、社会参与量表对新乡市5个社区的老年人进行调查，对数据进行描述性统计、方差分析及相关分析，采用Mplus 8.3构建链式中介效应模型。结果 实际共调查1 071名社区老年人，社区老年人PR得分为(48.81±5.66)分，老年人PR与身体功能、一般自我效能感、社会参与呈正相关(均P<0.05)。在纳入年龄、睡眠时间、居住方式等控制变量后，一般自我效能感、社会参与在身体功能与PR之间起链式中介效应，中介效应值为0.311，占总效应的55.24%。结论 老年人身体功能可直接影响PR，亦能通过一般自我效能感和社会参与间接影响PR。医务人员可以从提高老年人身体功能、自我效能感和社会参与水平着手，提升老年人PR水平。更多还原

【Abstract】 Objective This study investigates the mediating effects of general self-efficacy and social participation on the relationship between physical function and physical resilience(PR) among older adults. Methods The elderly in five communities selected by cluster sampling in Xinxiang City were surveyed using the Simplified Physical Fitness Test Scale,Physical Resilience Scale, General Self-Efficacy Scale, and the Social Participation Scale from March to November 2024.Descriptive statistics, variance analysis, and correlation analysis were conducted, and a chain mediation effect model was constructed using Mplus 8.3. Results A total of 1 071 elderly people in the community were surveyed, the PR score of the elderly in the community was(48.81±5.66), and the PR of the elderly was positively correlated with physical function, general self-efficacy, and social participation(all P<0.05). After including control variables such as age, sleep duration, and living arrangement, general self-efficacy and social participation played a chain mediating effect between physical function and PR,with a mediating effect value of 0.311, accounting for 55.24% of the total effect. Conclusion Physical function in the elderly can directly affect PR, and can also indirectly affect PR through general self-efficacy and social participation. The PR of older adults can be improved by improving their physical functioning, self-efficacy, and social participation.更多还原
