Health Economics Unit EuroQol grant success: support the use of EQ-5D instruments in China
Professor Nancy Devlin and Dr Tianxin Pan from the Health Economics Unit, in collaboration with Associate Professor Nan Luo (National University of Singapore) and colleagues from Nanjing Centre for Disease Control and Prevention, have been awarded an EuroQoL grant to investigate the effects of different interviewer-led data collection modes on EQ-5D data in China using a combination of qualitative and quantitative methods.
Studies have shown high ceiling effects in EQ-5D data collected from the Chinese general population (e.g., more than 80% for EQ-5D-3L and nearly 60% for EQ-5D-5L), potentially undermining the credibility and usefulness of the instruments. In China, large-scale population surveys typically use face-to-face interviews to administer fairly lengthy survey forms, which might impact on EQ-5D data collected. This project aims to understand the effect of interviewer-led mode on EQ-5D data collected in large-scale population surveys, and compare EQ-5D-3L and EQ-5D-5L in population health surveys in China.
