目的:探讨社区承诺量表(community commitment scale，CCS)在社区老年人中运用的信效度。方法:2020年5～8月采用社区承诺量表、防社交孤独社区自我效能量表(community\'s self-efficacy scale for prevent social isolation，CSES)对526名社区老年人进行问卷调查。并运用SPSS 25.0和AMOS 22.0软件对数据进行相关信度和效度分析。结果:社区承诺量表整体Cronbach\'s α系数为0.818，其中两个维度“社交感”和“归属感”的Cronbach\'s α系数分别为0.750和0.777，Guttman分半信度系数为0.799～0.835，重测信度为0.802。各条目-总分的相关系数为0.614～0.753(n P<0.05)。条目水平内容效度指数(I-CVI)为0.830～1.000，量表水平内容效度指数(S-CVI/UA)为0.875，平均内容效度指数(S-CVI/Ave)为0.972。经探索性因子分析提取到两个公因子，累积方差贡献率为57.019%。验证性因子分析各指标均达到适配标准(χn 2/n df＝2.638，RMSEA＝0.079，GFI＝0.957，AGFI＝0.918，TLI＝0.936，CFI＝0.956，IFI＝0.957)，标准化回归系数为0.63～0.80。n 结论:中文版社区承诺量表信效度良好，可用于评价社区老年人社会孤立情况。“,”Objective:To explore the reliability and validity of the community commitment scale (CCS) in community-dwelling elderly people.Methods:From May to August in 2020, a total of 526 community-dwelling elderly were investigated by community commitment scale, community\'s self-efficacy scale for preventing social isolation (CSES). SPSS 25.0 and AMOS 22.0 softwares were used to analyze the reliability and validity.Results:The overall Cronbach\'s α coefficient of the community commitment scale was 0.818, and the Cronbach\'s α coefficients of social and belonging dimensions were 0.750 and 0.777, respectively. The Guttman split-half reliability coefficients were 0.799-0.835, and the test-retest reliability was 0.802. Each item-to-total score correlations were 0.614-0.753 (alln P<0.05). The item level content validity index (I-CVI) was 0.830-1.000, the scale level content validity index (S-CVI/UA) was 0.875, and the average content validity index (S-CVI/Ave) was 0.972. Two common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 57.019%. The confirmatory factor analysis all indicators reached the adaptation standard (χn 2/n df=2.638, RMSEA=0.079, GFI=0.957, AGFI=0.918, TLI=0.936, CFI=0.956, IFI=0.957), and standardized regression coefficients were 0.63-0.80.n Conclusion:The Chinese version of the community commitment scale has good reliability and validity and can be used to evaluate the social isolation of the elderly in the community.
