The assessment of work-related functioning is a key process in vocational rehabilitation to identify specific domains of disability that can be considered within return to work strategies. The Work Rehabilitation Questionnaire (WORQ) was developed to evaluate work-related functioning based on the International Classification of Functioning, Disability, and Health (ICF) framework and is available in different languages. The aim of this study was to assess the French version of the WORQ using item response theory to further validate the scale. Rasch analysis of WORQ and the WORQ-BRIEF (a brief version of the WORQ) was performed using a calibration sample of 221 persons with musculoskeletal injuries. A four-testlet solution indicated the unidimensionality of WORQ, with no differential item functioning for age, education, physical job demands, and injury severity. Reliability was 0.969 and 0.918 for WORQ and WORQ-BRIEF, respectively. The minimal detectable change was calculated to be 4.2% of its operational range for WORQ and 8.5% for WORQ-BRIEF. Consequently, the French version of WORQ can be considered a good measure of work-related functioning in musculoskeletal conditions. WORQ can be used in rehabilitation practice to comprehensively identify the disability and guide clinical decision making and intervention planning. Further studies are needed to evaluate the psychometric properties of WORQ in other health conditions.
工作相关功能评估是职业康复中的一个关键过程，旨在确定可在重返工作策略中考虑的特定残疾领域。工作康复问卷（WORQ）是根据《国际功能、残疾和健康分类》（ICF）框架开发的，用于评估工作相关功能，有多种语言版本。本研究旨在使用项目反应理论评估 WORQ 的法语版本，以进一步验证该量表。对 221 名肌肉骨骼损伤患者的校准样本进行了 WORQ 和 WORQ-BRIEF（WORQ 的简短版本）的 Rasch 分析。四项测试的解决方案表明 WORQ 的具有一维性，年龄、教育、物理工作要求和损伤严重程度对项目无差异作用。WORQ 和 WORQ-BRIEF 的可靠性分别为 0.969 和 0.918。WORQ 的最小可检测变化值为其操作范围的 4.2%，WORQ-BRIEF 的最小可检测变化值为 8.5%。因此，WORQ 的法语版本可被视为肌肉骨骼疾病中工作相关功能的良好衡量标准。WORQ 可用于康复实践，全面识别残疾，并指导临床决策和干预计划。需要进一步研究评估 WORQ 在其他健康状况下的心理测量特性。
