Psychometric properties of the EQ-5D-5L for aboriginal Australians: a multi-method study
Abstract Introduction In Australia, health-related quality of life (HRQoL) instruments have been adopted in national population surveys to inform policy decisions that affect the health of Aboriginal and Torres Strait Islanders. However, Western-developed HRQoL instruments should not be assumed to c...
