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...
