An important consideration for studies that derive preference values or utilities using multi-attribute utility measures is the psychometric integrity of the measurement approach. Of particular importance is the requirement to establish whether multi-attribute utility measures generate utility scores that, in practice, reflect people’s preferences. We compared the empirical validity of EQ-5D versus SF-6D utility scores among participants of the 1996 Health Survey for England.
The study demonstrated 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. The results of this study were published in Health Economics in November 2005.
