Abstract: Abstract Objective To assess measurement properties of the two youth versions of EQ-5D (i.e., 5-level EQ-5D-Y [Y-5L] and 3-level EQ-5D-Y [Y-3L]) and KIDSCREEN-10 in China. Methods Children and adolescents attending schools in Shanghai, China were recruited to self-complete the Y-5L, KIDSCREEN-10, and Y-3L questionnaires. Their feasibility was assessed according to missing responses. Convergent validity of the EQ-5D-Y dimensions, a summated dimension score [SDS], and Visual Analogue Scale (VAS) were assessed by examining their correlations with the KIDSCREEN-10 index score and dimensions. Known-groups validity of SDS, VAS, and KIDSCREEN-10 index score were tested by comparing the scores of pupils with and without two conditions (i.e., overweight and shortsightedness), and the relative efficiency (RE) between them was also evaluated. Results A total of 262 pupils (girl: 58.4%; mean age: 12.7 years) were enrolled. Missing responses were low for both the Y-5L (0.3%) and Y-3L (2.4%), and KIDSCREEN-10 (0.3%). The overall ceiling effects were 40.3% for the Y-5L, 44.1% for the Y-3L and 1.1% for the KIDSCREEN-10. The SDSY-5L, SDSY-3L and VAS were moderately correlated with the KIDSCREEN-10 index score (|r|= 0.425 for SDSY-5L, 0.323 for SDSY-3L, and 0.435 for VAS; p 0.3). Both the SDSY-5L and SDSY-3L had lower values, and VAS and KIDSCREEN-10 index score had higher values for pupils without shortsightedness compared with those for their counterparts. The difference was statistical significance for the SDSY-5L and VAS (P
