Abstract

Objective To revised the Taiwan version successful aging inventory (SAI), and verify its reliability and validity in urban elderly in mainland China. Methods SAI was adjusted by culture and revised by pre-test to form a formal questionnaire. A sample of 600 elderly people in Guangzhou was chosen for a face-to-face questionnaire survey through convenient sampling. Half of the sample (n=300) was randomly selected for exploratory factor analysis, and the other was used to confirm the structural validity of SAI. Results Exploratory factor analysis extracted six common factors, including health autonomy, economic security, life adaptation, society and relative relationship, study and family. The cumulative contribution rate of six common factors was 65.366%. The fitting indexes of confirmatory factor analysis were χ2/df=1.861, CFI=0.930, IFI=0.930, TLI=0.923, GFI=0.823, RMSEA=0.054, RMR=0.073. There were significant ceiling effects in the four dimensions of health autonomy, economic security, life adaptation, and family. The internal consistency coefficient (Cronbach's α) of SAI was 0.930, and the test-retest reliability was 0.943. An average score of SAI ≥ 3.95 points was considered successful aging. Conclusion Reliability and validity of SAI are good, which can be used to measure the successful aging status of Chinese elders and track the effectiveness of health promotion measures. Key words: Successful aging; The elderly; Reliability; Validity

城市老年人成功老龄化量表的跨文化调整及其信度和有效性

目的对台湾版成功老龄化量表(SAI)进行修订，并验证其在中国大陆城市老年人中的信度和效度。方法采用培养法对SAI进行调整，并进行前测修正，形成正式的问卷。采用方便抽样的方法，选取广州市600名老年人进行面对面问卷调查。随机抽取一半样本(n=300)进行探索性因子分析，另一半样本用于验证SAI的结构效度。结果探索性因素分析提取出健康自主、经济安全、生活适应、社会及亲属关系、学习和家庭6个常见因素。6个公因子的累计贡献率为65.366%。验证性因子分析的拟合指标为χ2/df=1.861, CFI=0.930, IFI=0.930, TLI=0.923, GFI=0.823, RMSEA=0.054, RMR=0.073。健康自主、经济安全、生活适应、家庭四个维度均存在显著的天花板效应。SAI的内部一致性系数(Cronbach’s α)为0.930，重测信度为0.943。SAI平均评分≥3.95分为衰老成功。结论SAI的信度和效度较好，可用于衡量我国老年人的成功老龄化状况，跟踪健康促进措施的效果。关键词:成功老化;老年人;可靠性;有效性
