Numerous studies have explored the relationship between social participation, depression, cognitive function, and life satisfaction in community-dwelling older adults. However, the results of these studies were not consistent. Therefore, the in-depth excavation of the complex relationship mechanism between these four variables is limited. This study aims to explore whether depression and cognitive function act as the multiple mediators between social participation and life satisfaction in community-dwelling older adults.
This study used the meta-analytic structural equation modeling (MASEM) approach. Six databases were comprehensively searched to investigate the relationship between social participation, depression, cognitive function, and life satisfaction in community-dwelling older adults from inception to March 1, 2023.
The analysis included 50 articles that reported 66 effect sizes (N = 161,854). The MASEM found the relationship between social participation and life satisfaction was mediated by depression [β = 0.085, 95 % CI (0.053, 0.126)] and by cognitive function [β = 0.015, 95 % CI (0.002, 0.033)], respectively. Depression and cognitive function also played multiple mediating roles between social participation and life satisfaction in community-dwelling older adults [β = 0.005, 95 % CI (0.001, 0.012)].
There was not only a direct association between social participation and life satisfaction, but also an association through multiple mediating roles of depression and cognitive function in community-dwelling older adults. In the process of using diverse interventions to promote social participation in community-dwelling older adults, more attention should be paid to their psychological status and cognitive function to eliminate intrinsic barriers so as to improve life satisfaction effectively.
许多研究探讨了社区老年人的社会参与、抑郁、认知功能和生活满意度之间的关系。然而，这些研究的结果并不一致。因此，对这四个变量之间复杂关系机制的深入挖掘受到了限制。本研究旨在探讨抑郁和认知功能是否作为社区老年人社会参与与生活满意度之间的多重中介。
本研究采用元分析结构方程模型（MASEM）方法。从建库至 2023 年 3 月 1 日，全面检索了六个数据库，以调查社区老年人的社会参与、抑郁、认知功能和生活满意度之间的关系。
分析纳入了 50 篇报告 66 个效应量（N=161854）的文章。MASEM 发现，社会参与与生活满意度之间的关系分别通过抑郁[β=0.085，95%置信区间（0.053，0.126）]和认知功能[β=0.015，95%置信区间（0.002，0.033）]来介导。抑郁和认知功能在社区老年人的社会参与和生活满意度之间也起到了多重中介作用[β=0.005，95%置信区间（0.001，0.012）]。
社会参与与生活满意度之间不仅存在直接关联，还存在通过抑郁和认知功能的多重中介关联。在使用多种干预措施促进社区老年人的社会参与过程中，应更加关注他们的心理状态和认知功能，消除内在障碍，从而有效提高生活满意度。
