All translation/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. Only the EuroQol 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 reviewers.
