Purpose: Following systematic review and psychometric characteristics comparisons,
WOSI was identified as being superior over all existing shoulder instability selfassessment
scores. The purpose of this study is to translate and validate an existing
questionnaire related to shoulder instability; the Western Ontario Shoulder Instability
Index (WOSI) in a French version for patients from Quebec and France. Methods: A
standardized process for cross-cultural adaptation to develop and assess the French-
Canadian version was followed in two steps: the translation, and the validation of the
new French version. First, the WOSI was independently forward translated into two
French versions. The translators then met to achieve a consensus version. This
consolidated version was then back translated into English and cross-verified with
the original version. We then submitted this version to our French co-authors and an
acceptable version for both populations was elaborated Results: We were able to
obtain a French version adapted for patients from Quebec and France. Conclusion:
The WOSI_Fr was successfully translated from the original English version. A
reliability and validation process needs to be undertaken.
