EFAS Score – Multilingual Development and Validation of a Patient-Reported Outcome Measure (PROM) by the Score Committee of the European Foot and Ankle Society (EFAS)
Previous to this, only a few scores existed in languages other than English, such as the visual analogue foot and ankle (English, German, Italian, Thai). In 2018, development and validation was completed in 7 languages (German, English, French, Italian, Dutch, Swedish, Polish) and the score was published. 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. This is followed by the validation of other languages (Spanish, Portuguese, Finnish, Greek).
