Valuing health status of general population: Development of a Canadian specific preference-based scoring algorithm for EQ-5D-5L
The EQ-5D consists of 5 health dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension defines 3 levels indicating no problems, some problems, and extreme problems. It has been one of the most widely used utility-based quality of life instruments and its reliability and validity have been well-established around the world. Currently the EQ-5D is undergoing an important expansion from 3-level to 5-level response options with the aim at improving its ability to detect changes in health status and thus strengthening its application in health care research. The main objective is to develop a scoring algorithm for the EQ-5D-5L by eliciting preferences of Canadian general population.
