EQ-5D versions
EQ-5D in different languages
Currently there are more than 100 translated versions of EQ-5D. All translations/adaptations of EQ-5D are produced using a standardised translation protocol that conforms to internationally recognized guidelines. Only the EuroQol Group Executive Office can give permission for a translation to be performed and translations can only be stamped as official if they are performed in cooperation with EuroQol Group reviewers. For more information go to EQ-5D languages.
Alternative modes
EQ-5D was primarily designed for self-completion by the patient or respondent. However EQ-5D self-report data can also be collected using the following alternative modes of administration:
(i) Face-to-face
(ii) Self-completion in the presence of an interviewer
(iii) Telephone interview
(iv) Interactive Voice Response (IVR) versions
(v) Proxy

Future developments
Since 2002, the EuroQol Group Foundation has provided modest funding for EuroQol Group members to carry out innovative EQ-5D-related research. Since 2004, the Group has been establishing specific task forces to:
- Investigate the use of EQ-5D in different disease areas
- Develop a 5-level version of EQ-5D
- Explore different valuation methodologies for valuing EQ-5D health states
- Investigate the use of EQ-5D in population health
- Develop an EQ-5D youth version for young people and children in different languages: EQ-5D-Y. EQ-5D youth versions for children between of 8/9/10/11 years are currently available in UK English, Swedish, Italian, Spanish and German. The English version has been validated for use in Canada. A Dutch EQ-5D-Y version is in development.
- Explore the use of electronic versions of EQ-5D in pc and web-based applications as well as palm pilots and (in the future) cell phones. This task force will also investigate the eliciting of values via the computer
