An investigation into the empirical validity of the EQ-5D and SF-6D based on hypothetical preferences in a general population

Abstract

This study provides evidence that the SF-6D is an empirically valid and efficient alternative multi-attribute utility measure to the EQ-5D, and is capable of discriminating between external indicators of health status. However, health economists should also consider other psychometric properties, such as practicality and reliability, when selecting either measure for evaluative purposes.
