There is recent interest in using Discrete Choice Experiments (DCEs) to derive health state utility values and results can differ from Time Trade Off (TTO). Clearly DCE is 'choice-based' whereas TTO is generally considered to be a 'matching' task. We explore whether procedural adaptations to the...

Discrete choice experiments (DCEs) allow a number of characteristics to be traded-off against one another. An overriding methodological challenge faced is how best to apply DCEs to questions involving those attributes commonly used in value elicitation exercises such as risk, time (Bansback et...

In the conventional QALY model, people's preferences are assumed to satisfy utility independence. When health varies over time, utility independence implies that the value attached to a health state is independent of the health state that arise before or after it. In this paper we set out to...

Previous research has shown that people wish a premium to be placed on the prevention of certain types of deaths as they perceive those deaths as 'worse' than others. The research reported in this paper is an attempt to quantify such a 'bad death' premium via a discrete choice experiment (DCE)....

Expected Utility Theory (EUT) underlies the Standard Gamble (SG) method for eliciting people's preferences towards safety policy and risky treatments. Increasingly surveys using this method decompose the SG questions into two or more intermediate questions. Under the EUT assumption of procedural...

Quality-Adjusted Life Years (QALYs) estimate the utility derived from health states by taking account of life expectancy and quality of life. In applying QALYs to situations where health varies over time, it is usual to assume that we can add the utilities from constituent health states. This...

We consider the impact of introducing intermediate stages, chained together, into the Standard Gamble (SG) and Time Trade-Off (TTO) methods. We broadly replicate the patterns of responses observed in other SG studies. Less is known about the impact of intermediate stages, chained together, in...
