Mapping Healthy Days Scores to EQ-5D-5L Utilities: Development and Validation of an Algorithm Using Population Survey Data.
OBJECTIVES To develop and validate an algorithm for estimating EQ-5D-5L utility scores from the nonpreference-based Healthy Days (HD) instrument using direct and indirect mapping approaches. METHODS Data were drawn from the Queensland Preventive Health Survey for 2022 (N = 12 491) and 2023 (N = 12 679). Survey-weight...
