In a pilot study we investigate whether the inferences we draw about people's preferences towards health care treatments are altered if we vary the procedure that is used to elicit these preferences. In a conventional time trade-off (TTO) question, respondents express their preferences towards...

We consider the impact of introducing intermediate stages, chained together, into the standard gamble (SG) and time trade-off (TTO) methods. Less is known about the impact of intermediate stages, chained together, in the TTO method. We broadly replicate the patterns of responses observed in...

The conventional time trade off (TTO) method relies on fundamentally different procedures to assess states better than and worse than dead. Arbitrary transformation mechanisms are then applied to worse than dead scores in order to achieve symmetry with those rated as better than dead. We use a...
