The current study aimed to identify life satisfaction depending on the degree of social frailty and explore the mediating role of functional limitations and depressive symptoms between social frailty and life satisfaction. A secondary analysis of a cross-sectional survey was used. Data of 6,479 older adults were selected from the 2020 National Survey of Older Koreans. Of all participants, 2,595 (40.1%) and 1,605 (24.8%) had social prefrailty and frailty, respectively. Life satisfaction of participants with social frailty was significantly worse than those without social frailty. Social frailty negatively influenced life satisfaction. Functional limitations and depressive symptoms serially mediated the association between social frailty and life satisfaction. This mediation model provided evidence of the associations among social frailty, functional limitations, depressive symptoms, and life satisfaction in older adults. In community care settings, nurses should recognize the assessment of social frailty to enhance the subjective well-being of older adults. [Research in Gerontological Nursing, 16(6), 291-300.].

老年人社会脆弱性与生活满意度之间的关联：功能限制和抑郁症状的作用。

本研究旨在根据社交脆弱程度确定生活满意度，并探讨功能限制和抑郁症状在社交脆弱与生活满意度之间的中介作用。使用横断面调查的二次分析。6,479 名老年人的数据选自 2020 年全国老年人调查。在所有参与者中，分别有 2,595 名（40.1%）和 1,605 名（24.8%）患有社交脆弱和脆弱。有社交脆弱的参与者的生活满意度明显低于没有社交脆弱的参与者。社会脆弱性对生活满意度产生负面影响。功能限制和抑郁症状连续调节社交脆弱性和生活满意度之间的关联。这种中介模型提供了老年人社交脆弱、功能限制、抑郁症状和生活满意度之间关联的证据。在社区护理环境中，护士应认识到社会脆弱性的评估，以提高老年人的主观幸福感。[老年护理研究，16(6), 291-300.]。
