To determine the convergent validity and responsiveness of the work functioning impairment scale (WFun) in workers with musculoskeletal disorder-related pain.
Participants were extracted from an internet user study and prospectively examined using the pain intensity numerical rating scale (pain-NRS), the work ability numerical rating scale (productivity-NRS), and the WFun at baseline, 2 weeks, 6 weeks, and 3 months. The convergent validity and responsiveness of the WFun were examined by multilevel regression analysis.
A total of 786 workers participated and 593 completed all surveys. The WFun score gradually increased and decreased as the pain-NRS and the productivity-NRS increased, respectively. Changes in the WFun score steadily increased and decreased as changes in the pain-NRS and the productivity-NRS increased, respectively. Multilevel analyses showed that all linear associations were significant.
The convergent validity and responsiveness of the WFun were consistent with the expected direction and magnitude.
确定工作功能障碍量表（WFun）在与肌肉骨骼紊乱相关的疼痛患者中的聚合效度和反应度。
参与者从互联网用户研究中提取，并使用疼痛强度数字评定量表（疼痛 NRS）、工作能力数字评定量表（生产力 NRS）和 WFun 在基线、2 周、6 周和 3 个月进行前瞻性检查。通过多级回归分析检验 WFun 的聚合效度和反应度。
共有 786 名工人参与，其中 593 名完成了所有调查。WFun 评分随疼痛 NRS 和生产力 NRS 的增加而逐渐增加和减少。WFun 评分的变化随着疼痛 NRS 和生产力 NRS 的变化而逐渐增加和减少。多层次分析表明，所有线性关联均具有统计学意义。
WFun 的聚合效度和反应度与预期方向和幅度一致。
