[Measurement Properties and Value Set of EuroQol Five-Dimensional Questionnaire-Youth Version].

Objective To summarize the research findings on the measurement properties and value set of EuroQol Five-Dimensional Questionnaire-Youth Version (EQ-5D-Y). Methods PubMed,Web of Science,CNKI,and Wanfang Data were searched for the studies involving the measurement properties and value set of EQ-5D-Y. Results According to the inclusion and exclusion criteria,38 studies were included for analysis.EQ-5D-Y had good feasibility,reliability,and validity in measuring health-related quality of life (HRQOL) of youth in different countries and populations.The advantages of 5-level EQ-5D-Y (Y-5L)over 3-level EQ-5D-Y (Y-3L) might be modest.The available studies have demonstrated that the EQ-5D value set for adults should not be adopted in youth,and the international protocol for constructing the Y-3L value set has been available.Many countries have established or are developing their own Y-3L value sets according to the protocol. Conclusion The study systematically elaborated the current status and trend of the measurement properties and value set of EQ-5D-Y,which could provide reference for the future research on the EQ-5D-Y in China.
