Multilingual Development and Validation of a Patient-Reported Outcome Measure (PROM) by the Score Committee of the European Foot and Ankle Society (EFAS)

In 2013, the development and validation of the EFAS Score started. As there was no adequate validated foot and ankle score in different European languages, EFAS created a committee (Score Committee), inaugurated and headed by Martinus Richter, to develop, validate and publish a new score in common European mother tongues.

Language-specific validation

Validating a new score in different languages requires language-specific validation, not just the translation of an already validated score into another language. Therefore, validation in particular has been a very elaborate statistical process involving more than 2800 questionnaires of different languages. In 2018, development and validation of the EFAS Score was completed in 7 languages (Dutch, English, French, German, Italian, Swedish, Polish). The Finnish and Turkish score versions followed 2020, the Persian version 2021, and the Portuguese version 2022. Other language versions are under validation (Arabic, Danish, Estonian, Hungarian, Norwegian, Spanish). Non-native European languages such as Persian or Arabic have also been considered for validation to reflect the growing immigration.
