Abstract: Aim: To investigate if subjective life expectancy (SLE) impacts the willingness to trade‐off (WTT) and the number of years traded‐off in a 10‐years time trade‐off (TTO) exercise to obtain health state valuations. Methods: An Internet‐based questionnaire was administered in a sample representative for the Dutch general public. Next to basic demographic characteristics and SLE, respondents were asked to perform three TTO exercises. The following EQ‐5D health states were included 21211 (TTO1), 22221 (TTO2) and 33312 (TTO3). The WTT was studied using a probit regression model. The number of years traded‐off was investigated using a generalized negative binomial regression model. The independent variables used in both models were age, gender, quality of life, education, the difference between age and expected age of death (SLE), and a variable indicating whether the SLE was less than 10 years (SLE
