Which valuation protocol was used for the EQ-5D-5L?

A standardized valuation study protocol (called EQ-VT) was developed by the EuroQol Group to create standard value sets for the EQ-5D-5L. This protocol is based on the use of the composite time trade-off (cTTO) valuation technique, supplemented by a discrete choice experiment (DCE). We recommend EQ-5D-5L users to use the standard value sets, as these were produced with the EuroQol Group’s standardised valuation technology EQ-VT.
