In the past financial year, the EuroQol Research Foundation has funded or co-funded 60 scientific research studies, for a total value of more than 2,2 million euro. For more information on the EuroQol organization, click here.
The EuroQol Executive Committee is the principal scientific committee of the EuroQol organization. The Executive Committee is responsible for the scientific direction and for approving funding of research commissioned by the EuroQol Group. The table below shows research projects that were approved for funding from mid-2012 onwards.

The research efforts of the EuroQol Group are channelled through five Working Groups, each with their own objectives. In the table below, the research can be sorted by Working Group.
