How are new EQ-5D translations developed?

All translations/adaptations of EQ-5D are produced using a standardized translation protocol that conforms to internationally recognized guidelines. These guidelines aim to ensure equivalence to the English ‘source’ version and involve a forward/backward translation process and cognitive debriefing. No translation can receive official endorsement from the EuroQol Research Foundation, unless it has been performed in strict adherence according to the EuroQol Research Foundation’s translation guidelines. The agencies we work with are compliant with our requirements.
