Evaluation on reliability and validity of SF-36 Scale (Version 2) in urban residents' quality of life in Chongqing
AIM: To evaluate the reliability, validity and feasi-bility of the Version 2 of SF-36 Scale in urban residents' quality of life in Chongqing. METHODS: Through multistage stratified sampling, the quality of life in 738 urban residents in Chongqing was assessed with SF-36 (Version 2)and WHOQOL-BREF. The repetitive reliability, internal consistency, criterion-related validity and construct validity of the scale were tested. RESULTS: The internal constancy was good and Cronbaeh's α coefficient was 0.8041. The test-retest correlation coefficient was 0.763. The factor analysis showed that the eight factors were all similar to the theory construction and the total variance contribution of construct validity was 62.2%. SF-36 was related with WHOQOL-BREF and correlation coefficient was 0.424. CONCLUSION: Version 2 of the SF-36 Scale is good for the measurement and assessment of quality of life of urban residents in Chongqing.
