Data collection has successfully started

After successfully completing a pilot phase of interviewer training and data collection at the end of 2022, we are pleased to announce that the first participant in the new UK EQ-5D-5L valuation study was interviewed on 29 January 2023. Interviewer data will be collected online and face-to-face, to allow as many people to participate as possible.

To date approximately 125 interviews of the 1200 planned interviews have been collected in the valuation study and the expected end of data collection is end of summer 2023. The first interim analysis for in-depth checking of data quality and modelling results by the independent Quality Control team is pre-scheduled for Mid-March. This important study is being led by Professor Donna Rowen and is supported by the EuroQol Research Foundation.
