Abstract: Abstract Objectives To explore the comparative performance and develop the mapping algorithms between EQ-5D-5L and SF-6Dv2 in China. Methods Respondents recruited from the Chinese general population completed both EQ-5D-5L and SF-6Dv2 during face-to-face interviews. Ceiling/floor effects were reported. Discriminative validity in self-reported chronic conditions was investigated using the effect sizes (ES). Test–retest reliability was evaluated using intra-class correlation coefficient (ICC) and Bland–Altman plots in a subsample. Correlation and absolute agreements between the two measures were estimated with Spearman’s rank correlation coefficient and ICC, respectively. Ordinary least squares (OLS), generalized linear model, Tobit model, and robust MM-estimator were explored to estimate mapping equations between EQ-5D-5L and SF-6Dv2. Results 3320 respondents (50.3% males; age 18–90 years) were recruited. 51.1% and 12.2% of respondents reported no problems on all EQ-5D-5L and SF-6Dv2 dimensions, respectively. The mean EQ-5D-5L utility was higher than SF-6Dv2 (0.947 vs. 0.827, p
