Chinese version of SF-36 in the quality of life assessment among community-dwelling elders / 中南大学学报(医学版)

ABSTRACT

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.
