FAQS | EQ-5D-3L
Evidence on the implications for cost-effectiveness ratios when switching from EQ-5D-3L to EQ-5D-5L is limited. Some work has been done on this, using mapping instead of a direct comparison of the EQ-5D-3L and EQ-5D-5L (see Wailoo et al, 2021), showing that there are differences, but that these differences are not unidirectional between countries. Furthermore, simulation…
Read MoreResponses to the EQ-5D-5L and EQ-5D-3L may differ as their descriptive systems are different. For example, the most extreme response option on the mobility dimension is “confined to bed” in the EQ-5D-3L and “unable to walk about” in the EQ-5D-5L, which may lead to different responses from respondents. The expanded level structure and the different…
Read MoreThere is growing evidence on the comparative psychometric performance of the EQ-5D-3L and EQ-5D-5L descriptive systems. A published systematic review by Buchholz and colleagues found that the 5-level version performed better, or at least the same in terms of measurement properties when compared to the 3-level version. This review supports the use of both the…

Read MoreThe time trade-off (TTO), visual analogue scale (VAS) and discrete choice experiment (DCE) value sets differ in the technique used to elicit the values for the models. In the TTO task, respondents are asked to imagine they live in a certain suboptimal health state for 10 years and then to specify the amount of time…
