PURPOSE: To measure health-related quality of life in the Chinese population using three universal health utility scales (CQ-11D, EQ-5D-5L, and SF-6D) and to compare the differences in the results obtained by the different scales to provide a reference for future utility on health-related quality of life in the Chinese population. METHODS: According to the Chinese population's distribution area, gender, and age, quota sampling was conducted. Three scales, CQ-11D, EQ-5D-5L, and SF-6D, whose results were self-reported, were collected in succession after collecting respondents' demographic information. The health utility value and floor/ceiling effect were explained. Bland-Altman was used to evaluate the consistency, the intraclass correlation coefficient was used to evaluate the correlation, and the receiver operating characteristic curve was used to evaluate the discriminative validity of the scale. RESULTS: The mean utility values of the CQ-11D, EQ-5D-5L, and SF-6D scales, respectively, were 0.891, 0.927, and 0.841. The floor effect did not appear in any of the three scales, but the ceiling effect did, and the EQ-5D-5L ceiling effect was the most severe. The limits of the agreement interval for CQ-11D versus EQ-5D-5L in the total sample population were (-0.245,0.172); for CQ-11D versus SF-6D, they were (- 0.256,0.354); and for EQ-5D-5L versus SF-6D, they were (-0.199,0.371). The consistency of the three scales is satisfactory overall. In the total population, the intraclass c...
