中文修正版社会生产函数幸福感水平评定量表在社区老年人群中应用的信效度研究

Reliability and Validity of Chinese Revision of the 15- item Version of the Social Production Function Instrument for the Level of Well- being in the Community Elderly

目的 评价中文修正版社会生产函数幸福感水平评定量表〔SPF-IL（s）-CHI〕在社区老年人群中应用的信度和效度。方法 于2015年4—6月,采用方便抽样法,抽取山东省济宁市3个社区自愿参与调查的老年人为研究对象。采用SPF-IL（s）-CHI对社区老年人进行问卷调查,共发放问卷460份,回收有效问卷442份,有效回收率为96.1%。量表效度分析指标包括：各条目得分与相应维度得分及总分的相关性、内容效度、结构效度;量表信度分析指标包括：量表内部一致性Cronbach＇sα系数、量表各维度内部一致性Cronbach＇sα系数、重测信度、分半信度。结果 各条目得分与相应维度得分及总分均呈直线正相关（P〈0.05）。条目水平的内容效度指数（I-CVI）为0.80-1.00,量表水平的内容效度指数（S-CVI/UA）为0.80,平均量表水平的内容效度指数（S-CVI/Ave）为0.96。经探索性因子分析（EFA）,采用主轴因子提取法得5因子模型,各条目共同度为0.482-0.878。经验证性因子分析（CFA）得卡方自由度比值（CMIN/DF）=2.142,渐进残差均方和平方根（RMSEA）=0.072,适配度指数（GFI）=0.907,非规整适配度指数（TLI）=0.941,增值适配度指数（IFI）=0.956,比较适配度指数（CFI）=0.955,简约适配度指数（PGFI）=0.604,标准化回归系数为0.37-0.97。量表内部一致性Cronbach＇sα系数为0.914,情感、行为确认、地位、舒适感、激励5个维度的内部一致性Cronbach＇sα系数分别为0.779、0.814、0.853、0.938、0.690,重测信度为0.902,分半信度为0.861。结论 SPF-IL（s）-CHI信效度良好,可用于评价我国社区老年人的主观幸福感状况。

Objective To evaluate the reliability and validity of Chinese revision of the 15 - item version of the social Production function instrument for the level of well - being [ SPF - IL （s） - CHI ] in the community elderly. Methods From April to June in 2015, the elderly from three communities of Jining in Shandong Province who volunteered to participate in the survey were selected by adopting convenience sampling method. The elderly were investigated by using SFP - IL （s） - CHI, 460 questionnaires were sent out, and 442 were recovered with an effective response rate of 96. 1%. The indicators of analyzing the validity of the scale included the correlation between scores of each item and corresponding dimensional scores and total scores, content validity and structural validity; the indicators of analyzing the reliability of the scale included Cronbach＇s a coefficient of internal consistency of the scale, Cronbach＇s α coefficient of all the dimentsions＇ internal consistency of the scale, test - retest reliability and split - half reliability. Results Scores of each item were linearly positive correlated with the corresponding dimensional scores and total scores （P 〈 0. 05） . The content validity index of items level （I -CVI） was from 0. 80 to 1.00, the content validity index of scale level （ S - CVI/UA ） was 0. 80 and content validity index of average scale level （ S - CVI/Ave） was 0. 96. After exploratory factor analysis, five factors models were got by using principal axis factor extraction method, and the eommunalities of the items were 0. 482 - 0. 878. With confirmatory factor analysis, the degree of freedom of chi - square （CMIN/DF） , root mean square error of approximation （RMSEA） , goodness - of - fit index （GF1） , tall latte index of non - normalized goodness - of - fit （TLI） , incremental fit index （IFI） , comparative fit index （CFI） , parsimony goodness - of -fit index （PGFI） and standardized regression coefficient were 2. 142, 0.072, 0.907, 0.941, 0.956, 0.955, 0.604 and 0. 37 -0. 97 respectively. The Cronbach＇s α coefficient of internal consistency of scale was 0. 914, Cronbach＇s α coefficients of internal consistency of the five dimensions such as emotion, behavioral confirmation, position, comfortable sensation and motivation were 0. 779, 0. 814, 0. 853, 0. 938 and 0. 690 respectively, the test - retest reliability was 0. 902 and the split - half reliability was 0. 861. Conclusion The reliability and validity of SPF - IL （s） - CHI is good and can be used for evaluating the well - being status of the elderly in community of our country.
