Validation and comparison of five preference-based measures among age-related macular degeneration patients: evidence from mainland China.

The AQoL-7D had shown better psychometric properties than other four PBMs based on Chinese AMD inpatients. The EQ-5D-5L demonstrated sufficient psychometric properties and given the availability of a Chinese-specific tariff and the recommendations of China guidelines for pharmacoeconomic evaluations, it may be prioritized to be used in China. Capability wellbeing instruments could also be considered given they provide information that goes beyond health. Further evidence on responsiveness and reliability for all five PBMs among AMD patients is required.
