摘要: 目的 探讨并构建我国健康人社会功能性衰老评估指标体系,制作人体社会功能性衰老量表。方法 采用文献搜集、改良Delphi法和层次分析法(analytic hierarchy process,AHP)筛选并确立社会功能性衰老评估指标体系及权重系数;通过信度、相关性和探索性因子分析等评价量表的信度、效度并提取指标。结果 确定社会维度衰老指标体系,其中二级指标3项(即个人能力、社会参与、组织交往),三级指标13项(生活自理能力、人际关系等);量表信度克朗巴哈α系数为0.873,重测信度系数r为0.848(P<0.001),内容效度指数(content validity index,CVI)为0.836;结构效度经因子分析共提取3个公因子,能解释总变异量的53.69%,各原始指标公共度介于0.573~0.776之间。结论 建立的社会功能性衰老指标体系,指标代表性好、认可度较高;量表的内容和结构效度较理想,指标分值及离散度与总分的相关系数大部分达到统计学标准,具有较好的应用价值和实用价值。Abstract: Objective A index system was established to evaluate social function of aging of healthy life from the perspective of epidemiology, sociology and elderly health care with guide of modern medical model. Methods Social function of aging evaluation index system and weight coefficient were established by literature collection, modified Delphy (Delphi) and analytic hierarchy process (AHP). The reliability and validity of the scale were evaluated through internal consistency reliability analysis, correlation analysis, and exploratory factor analysis as well as indicator extraction. Results Three aspects and 13 indicators were ultimately included according to the mean and coefficient of variation of importance and feasibility score. The Cronbach's α coefficient of the scale was 0.873. The test-retest reliability coefficient was 0.848 (P<0.001), and CVI (content validity index) was 0.836. Three common factors were extracted through the construct validity analysis which accounted for 53.69% of the variance of the original indicators with factor analysis, the communality of the indicators were 0.573-0.776. Conclusions Those indexes are of good representation and recognition. Indicators included reliability, content validity index, and construct validity are also good. The dispersion of index score, the correlation coefficient of index score with total score and load of each factor are basically reached the related standard. It can provide the judgment of aging for any one and had good value and prospect.
