title: [Chinese version of SF-36 in the quality of life assessment among community-dwelling elders].
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.
  
  
  CONCLUSIONS
  The SF-36 is practical in studying the quality of life among community-dwelling elders.
