中文版SF-36在社区老年人生存质量评价中的应用

目的：用普适性健康问卷SF-36量表测量长沙市老年人的生存质量，考核SF-36表的信度、效度，分析比较不同老年人群各领域得分：方法：采用多阶段随机抽样，调查602名在长沙市居住1年以上60岁及60岁以上老年人。用分半系数和Cronbach’s α信度系数分析SF-36信度，主成分因子分析和相关分析等方法分析效度；方差分析、单变量t检验等方法检验不同老年人群生存质量得分。结果：SF-36的分半系数为0．72，各领域信度系数均大于0．8；主成分因子分析SF-36可分为8个领域和2个综合测量指标；各条目与其所属领域相关系数绝对值均大于0．59。不同年龄、哇别、文化程度、职业、婚姻状况的老年人群生存质量不同。结论：SF-36可以用于社区老年人生存质量的研究。

OBJECTIVE: To obtain scores in a community-dwelling population over 60 using the SF-36, to assess the reliability and validity of this general health questionnaire, and to analyze the difference in dimension scores among the elderly Chinese in Changsha. METHODS: We randomly selected 602 elders, aged 60 to 91 years, in multi-phases. All the subjects had resided in Changsha for at least one year. The reliability of the SF-36 was assessed by split-half reliability and Cronbach's alpha coefficient and the validity through factor analysis and correlation analysis, etc. The dimension scores of different people were obtained by analysis of variance and independent-samples t-test. RESULTS: The split-half reliability was 0.72 and the Cronbach's alpha coefficients of all the 8 dimensions were more than 0.8; the Pearson correlate coefficients of all the items to their dimensions were more than 0. 59. SF-36 contained 8 domains and 2 summary scales in the factor analysis. Health-related quality was different in different elders. CONCLUSION: The SF-36 is practical in studying the quality of life among community-dwelling elders.
