DEVLOPMENT AND EVALUATION OF CHINESE VERSION OF SHORT FORM 8

[Objective]To develop the Chinese version of Short Form 8(SF-8)and test the reliability and validity.[Methods]The Chinese version of SF-8 was developed by translation and back translation.Chinese version of SF-8 was used to measure Chengdu citizen' quality of life in a cross-sectional study.Cronbach' α coefficient was calculated to evaluate the internal consistency;criterion validity was calculated with SF-36 as criterion;factor analysis was used to evaluate construct validity.[Results]Cronbach' α coefficient of SF-8 was 0.749;correlation coefficient between SF-8 and SF-36 was 0.559;the 3 factors mental health,physical health and integrated health,were sorted,which accounted for 71.71% of the scale's total variances.[Conclusions]The study suggests that the SF-8 has satisfactory reliability and validity,and it can be used in Chinese population.But we should pay attention to the requirement for sensitivity of the survey,when we select SF-8 to measure the quality of life.
