The SF-6D, and the SF-12 health status questionnaire from which it is derived, is widely used in clinical practice, population health monitoring, and health research in NZ, without evidence of its validity for this population or the availability of a utility value set based on preferences elicited from the NZ population.
This mixed methods project will combine qualitative kaupapa Māori research methods to evaluate the appropriateness of the SF-6D for the NZ, and especially Māori, population; instrument development if required to refine the SF-6D to meet the needs of the NZ population and healthcare system; and cutting-edge discrete choice experiment (DCE) survey methods to develop a value set reflecting the preferences of the NZ population for the trade-offs between health-related quality of life domains inherent in healthcare prioritisation and funding decisions.
