Purpose The Work Rehabilitation Questionnaire (WORQ) is a patient-reported instrument to assess work related functioning in vocational rehabilitation (VR) and work, based on the International Classification of Functioning, Disability and Health (ICF) core set for VR. The objective of this study was to cross-culturally adapt WORQ to French and to evaluate its psychometric properties. Methods The cross-cultural adaptation followed a dual-panel approach. Psychometrics was examined in one VR-centre in the French speaking part of Switzerland. Test–retest reliability was analyzed with intraclass correlation coefficient (ICC), internal consistency was assessed with Cronbach’s alpha. Construct validity was determined by convergence to the self-reported general functioning scale and the Hospital Anxiety and Depression Scales (HADS). The association of patient’s return-to-work expectation within 6-months and having a case manager was examined. The usability of WORQ-French was tested in 10 VR patients. Results Eighty-nine patients with musculoskeletal injuries were included. WORQ-French showed excellent internal consistency (0.968) and a high test–retest reliability (0.935). WORQ-French was positively associated with self-reported general functioning (r = 0.662) and both HADS scales (r = 0.56–0.57). Neither the patient’s return-to-work expectation nor having a case manager were significantly correlated with WORQ-French. Usability in terms of understandability of questions and response options was found to be good. Seven patients rated the length of WORQ-French as good, while two found the instrument a little too long and one found it too long. Conclusions WORQ French is a valid, reliable, and easy to administer instrument to assess self-reported work functioning given our study setting and sample characteristics.
