The methodology of valuing health states remains a key issue in the construction of health-related quality of life measures. Different scaling methods appear to yield different sets of valuations, and as yet there is no consensus as to which method is the preferred technique. Many of the...

This paper tests the consistency of health utility measurements with individual preferences. We compare three methods, the time trade-off, the standard gamble and a version of the standard gamble that corrects for the deviations from expected utility modelled by prospect theory. Individual...

Few studies have compared preference values of health states obtained in different countries. This paper applies a nonparametric model to estimate and compare EQ-5D health state valuation data obtained from two countries using Bayesian methods. The data set is the US and UK EQ-5D valuation...

Two key questions in the context of UK health policy are: do the published preference indices for EQ-5D reflect the impact of lost earnings? Are we currently implicitly including indirect costs in our analyses? It is crucial to investigate whether or not individuals take into account any...

We compare two settings for administering time trade-off (TTO) tasks in computer-assisted interviews (one-to-one, interviewer-led versus group, self-complete) by examining the quality of the data generated in pilot studies undertaken in England and the Netherlands. The two studies used...

This paper reports the estimation of a preference-based scoring algorithm for a new dependency health state classification system. According to this system health states are described as a combination of 6 attributes (eat, incontinence, personal care, mobility, housework and cognition/mental...
