Purpose Musculoskeletal disorders (MSDs) are often associated with long-term sick leave, productivity loss, and reduced work functioning. However, measures that assess work-related functioning are sparse. Objective To assess the psychometric properties of the Work Rehabilitation Questionnaire (WORQ)-German version in patients with MSDs in an outpatient physical therapy practice. Methods Psychometric study including patients with MSDs with restricted work participation. Data was collected in a single physical therapy outpatient clinic. For construct validity, we developed a priori hypotheses on the correlation between the functioning part of WORQ (40 items) and other questionnaires with similar concepts. For test-retest reliability, WORQ was administered twice, 7 days apart. We examined internal consistency (Cronbach's Alpha) and Minimal Detectable Change (MDC). Feasibility of WORQ was examined using feedback from patients and physical therapists. Results There were 51 study participants. Test-retest of WORQ sum score was 0.80 (p < 0.01) (Spearman's rho). Internal consistency was 0.94 and MDC established at 9.2%. WORQ correlated with general health (r = - 0.49), with HADS (r = 0.55), and with quality of life (WHOQOL) (r = - 0.47). WORQ had the highest correlation with WHODAS 2.0 (r = 0.81). Patients rated WORQ as easy to answer and meaningful to their experience. Conclusions When evaluating self-reported work-related functioning, the WORQ-German version was demonstrated to be a valid, reliable, and easy to administer questionnaire for our sample of patients with MSDs in an outpatient PT clinic.
目的 肌肉骨骼疾病（MSD）常与长期病假、生产力下降和工作功能降低有关。然而，评估与工作相关的功能的措施却很少。 目的 在物理治疗门诊实践中，评估肌肉骨骼疾病患者使用工作康复问卷（WORQ）-德语版的心理测量学特性。 方法 包括工作参与受限的 MSD 患者的心理测量学研究。数据在一家物理治疗门诊收集。为了进行结构效度评估，我们根据 WORQ 的功能部分（40 个项目）与具有类似概念的其他问卷之间的相关性，提出了先验假设。为了评估重测信度，WORQ 在相隔 7 天的时间里进行了两次测试。我们检查了内部一致性（Cronbach's Alpha）和最小可检测变化（MDC）。WORQ 的可行性通过患者和物理治疗师的反馈进行评估。 结果 共有 51 名研究参与者。WORQ 总分的重测信度为 0.80（p<0.01）（Spearman's rho）。内部一致性为 0.94，MDC 为 9.2。WORQ 与一般健康状况（r=-0.49）、HADS（r=0.55）和生活质量（WHOQOL）（r=-0.47）相关。WORQ 与 WHODAS 2.0 的相关性最高（r=0.81）。患者认为 WORQ 易于回答，对他们的体验有意义。 结论 在评估自我报告的与工作相关的功能时，WORQ-德语版在我们的门诊物理治疗诊所的 MSD 患者样本中表现出了有效性、可靠性和易于管理的特点。
