Abstract

Purpose The Work Rehabilitation Questionnaire (WORQ) was developed to evaluate work functioning in vocational rehabilitation, but was not yet available in Dutch. The goal of this study is twofold: a description of the cross-cultural adaptation process (part 1) of the WORQ to be used in Flanders (The Dutch speaking part of Belgium, WORQ-VL) and a presentation of the first psychometric testing of the WORQ-VL (part 2). Methods For part 1, the guidelines for cross-cultural adaptation of self-report measures by Beaton et al. were used to structure the cross-cultural adaptation. For part 2, a cross-sectional study was conducted in patients with musculoskeletal disorders [sample A: hand and wrist rehabilitation (n = 21) and sample B: fibromyalgia patients (n = 93)] who completed the WORQ-VL. Internal consistency and factor structure were examined in the total sample, whereas convergent and discriminant validity of the WORQ-VL were researched in sample A. Results First results on the convergent validity and discriminant validity (small sample size) and internal consistency of the WORQ-VL are promising. The exploratory factor analysis revealed seven factors which were labeled as 'cognition', 'physical', 'mood', 'activities of daily living', 'sensory', 'emotional' and 'social'. The best evidence was found for the 'physical' subscale of the WORQ-VL: strong correlations were found with the 'physical functioning' and 'role limitations-physical' subscales of the Short-Form Health Survey, respectively r = - .84 and r = - .59, p < .01. As expected, predominantly weak correlations were found with hand grip strength, kinesiophobia, hand-related aesthetics and satisfaction (ranging between r = - .38 and r = .34, p > .05). Conclusions The WORQ-VL is a user-friendly and valuable ICF-based self-report questionnaire to evaluate work functioning. Future studies are highly needed to examine the value of the WORQ within different patient populations and settings in order to examine further the added value of this self-report measure.
