The incorporation of the state ‘dead’ in the DC models produces results in concordance with DC models that do not include ‘dead’. </AbstractSection> Copyright The Author(s) 2013

Different lead-time time trade-off variants should be carefully studied in order to achieve the best measurement of health-state values using this new method. </AbstractSection> Copyright The Author(s) 2013

The utility was higher for the PFS state than baseline, but decreased below baseline in non-response and disease progression states. AEs had an impact on utility within the PFS response state. The severe infection AE had a greater impact on utilities for the responding to treatment state...

This article examines the effect that different specifications of the time trade-off (TTO) valuation task may have on values for EQ-5D-5L health states. The new variants of the TTO, namely lead-time TTO and lag-time TTO, along with the classic approach to TTO were compared using two durations...

Este trabajo aplica un método, propuesto inicialmente por Miyamoto (2000), para ajustar los pesos de calidad de vida (o utilidades de los estados de salud) en función de la curvatura de la función de utilidad del tiempo de vida. El procedimiento de ajuste aplicado es robusto ante fenómenos...

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...

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 question, respondents express their preferences towards...

A relatively new approach to measure health status is to use non-parametric frontier methods, based on index and production theory. The purpose of this study is to construct and investigate some properties of a non-parametric health status index. The index is based on a non-radial efficiency...

This paper tests the internal consistency of time trade-off utilities. We find significant violations of consistency in the direction predicted by loss aversion. The violations disappear for higher gauge durations. We show that loss aversion can also explain that for short gauge durations time...
