ABSTRACT
Objective By review of the studies comparing the measurements properties of EuroQol five-dimensional questionnaire (EQ-5D) and short-form 6-dimension health survey (SF-6D) in Chinese populations,this study aims to provide a reference for selecting,applying,and improving the health-related quality of life and health utility measurement tools for Chinese populations.Methods We retrieved the original studies which compared the two tools from both Chinese and English databases and then summarized the findings of the included studies from the measurement properties.Results A total of 12 studies were screened out,including 9 studies about diseased populations and 3 studies about the general populations.The included studies generally demonstrated that both EQ-5D and SF-6D had good feasibility,while the utility scores generated from them cannot be used interchangeably.For the diseased populations,both EQ-5D and SF-6D and their utility scores had good construct validity,including convergent and known-groups validity,while only the utility scores had good construct validity for the general populations.For the diseased populations,SF-6D had smaller ceiling effect and better sensitivity than EQ-5D-3L,while the comparison results between SF-6D and EQ-5D-5L were inconsistent.For the general populations,SF-6D also had better sensitivity than EQ-5D.In addition,there was little comparative evidence for reliability such as test-retest reliability and responsiveness between SF-6D and SF-6D in the two populations.Conclusion This review summarized the characteristics,methods,results,and conclusions of the studies that directly compared the two tools for the populations in China.Although only the studies directly comparing EQ-5D and SF-6D are included in this review,the common findings in these studies provide a basis for better comparison between the two in the future.
