OBJECTIVES: To compare the discriminatory power between EQ-5D-5L(5L) and EQ-5D-3L(3L) for general population in China. METHODS: Sample was collected from a survey of health related quality of life for general population in China that was conducted in Beijing, Chengdu, Nanjing and Shenyang. Performance was analyzed in terms of ceiling effect, redistribution properties and discriminatory power in the two versions of EQ-5D. Apart from analyzing the performance, we further identified the differences between urban and rural residents. RESULTS: A total of The proportion of choosing fully health state decreased from % (3L) to (5L), which was mainly due to the reduction of ceiling effect in the two dimensions: “pain/discomfort” and “anxiety/depression”. The overall ceiling effects of urban and rural samples decreased by 12.94% and 10.21%, respectively. As for redistribution properties, 6.93% of responses were inconsistent, where “pain/discomfort” and “anxiety/depression” dimensions contributed the most. The proportion of inconsistent was 8.96% in rural sample while 4.93% in urban sample. In terms of Shannon’s indices, the H’ values of 5L were higher than those from 3L in each dimension: “mobility” (0.31 vs. 0.22), “self-care” (0.14 vs. 0.10), “usual activities” (0.32 vs.0.19), “pain/discomfort” (1.07 vs. 0.75), and “anxiety/depression” (0.85 vs. 0.58), indicating better discriminatory power for CONCLUSIONS: Compared with three-level version, EQ-5D-5L can reduce the ceiling effect and improve the discriminatory power when identifying different health status.
