To evaluate the responsiveness to change of a modified version of the Work module of the Disabilities of the Arm, Shoulder, and Hand (DASH-W) in a prospective, longitudinal cohort study of active workers.
We compared change on a 1-year recall modified DASH-W to change on work ability, work productivity, and symptom severity, according to predetermined hypotheses following the Consensus-based standards for the selection of health measurement instruments (COSMIN). We evaluated concordance in the direction of change, and magnitude of change using Spearman rank correlations, effect sizes (ES), standardized response means (SRM), and area under the receiver operating characteristic curves (AUC).
In a sample of 551 workers, change in 1-year recall modified DASH-W scores showed moderate correlations with changes in work ability, work productivity, and symptom severity (r = 0.47, 0.44, and 0.36, respectively). ES and SRM were moderate for 1-year recall modified DASH-W scores in workers whose work ability (ES = -0.58, SRM = -0.52) and work productivity improved (ES = -0.59, SRM = -0.56), and larger for workers whose work ability (ES = 1.24, SRM = 0.68) and work productivity worsened (ES = 1.02, SRM = 0.61). ES and SRM were small for 1-year recall modified DASH-W scores of workers whose symptom severity improved (-0.32 and -0.29, respectively). Responsiveness of the 1-year recall modified DASH-W was moderate for those whose symptom severity worsened (ES = 0.77, SRM = 0.50). AUC met responsiveness criteria for work ability and work productivity.
The 1-year recall modified DASH-W is responsive to changes in work ability and work productivity in active workers with upper extremity symptoms.
在一项针对在职员工的前瞻性纵向队列研究中，评估改良版手臂、肩部和手部功能障碍工作模块（DASH-W）对变化的反应性。
根据基于共识的健康测量工具选择标准（COSMIN）中的预定假设，我们将1年回忆期改良版DASH-W的变化与工作能力、工作效率和症状严重程度的变化进行了比较。我们使用Spearman等级相关性、效应大小（ES）、标准化反应均值（SRM）和受试者工作特征曲线下面积（AUC）评估了变化方向的一致性和变化幅度。
在551名员工的样本中，1年回忆期改良版DASH-W得分的变化与工作能力、工作效率和症状严重程度的变化呈中度相关（分别为r = 0.47、0.44和0.36）。对于工作能力（ES = -0.58，SRM = -0.52）和工作效率提高（ES = -0.59，SRM = -0.56）的员工，1年回忆期改良版DASH-W得分的ES和SRM为中度；对于工作能力（ES = 1.24，SRM = 0.68）和工作效率恶化（ES = 1.02，SRM = 0.61）的员工，ES和SRM更大。对于症状严重程度改善的员工，1年回忆期改良版DASH-W得分的ES和SRM较小（分别为-0.32和-0.29）。对于症状严重程度恶化的员工，1年回忆期改良版DASH-W的反应性为中度（ES = 0.77，SRM = 0.50）。AUC符合工作能力和工作效率的反应性标准。
1年回忆期改良版DASH-W对有上肢症状的在职员工的工作能力和工作效率变化有反应。
