The aim of this study was to examine the responsiveness of the Arabic Disabilities of the Arm, Shoulder and Hand (DASH) and to quantify its minimal important change (MIC) for improvement. People with upper extremity musculoskeletal problems who were receiving physical therapy were evaluated at baseline and again during a follow-up appointment, with a median time frame of 7 days between the two testing sessions (range of 6 to 72 days). The participants completed the Arabic DASH, Global Assessment of Function (GAF), Numeric Pain Rating Scale (NPRS) and Global Rating of Change Scale (GRC). The responsiveness of the Arabic DASH was assessed by examining the pre-specified hypotheses. The MIC for improvement was determined using the receiver operating characteristic method (MIC) and the predictive modeling method (MIC). As hypothesized, a change in the Arabic DASH demonstrated a significant positive correlation with changes in the GAF (r = 0.69), NPRS (r = 0.68) and GRC (r = 0.73). Consistent with our hypotheses, the DASH change scores could be used to differentiate between participants who improved and those who did not improve (area under the receiver operating characteristic curve = 0.87), and they showed a large magnitude of change (effect size = 1.53, standardized response mean = 1.42) in patients who improved. All the hypotheses specified a priori were supported by the results. The Arabic DASH MIC and MIC were estimated to be 14.22 and 14.85. The interaction between the DASH change and baseline score was not a significant predictor of status (improved vs. not improved) ( = 0.75), indicating that the DASH MIC was not baseline-dependent. The Arabic DASH demonstrated sufficient responsiveness, supporting the idea that the Arabic DASH is capable of detecting changes in upper extremity function over time. The value of the Arabic DASH MIC was similar when estimated using the predictive modeling and ROC methods, and the MIC was not dependent on baseline status.
本研究旨在检验阿拉伯语版上肢、肩部和手部功能障碍量表（DASH）的反应性，并量化其改善的最小重要变化（MIC）。对接受物理治疗的上肢肌肉骨骼问题患者在基线时进行评估，并在随访预约时再次评估，两次测试之间的中位时间间隔为7天（范围为6至72天）。参与者完成了阿拉伯语版DASH、功能总体评估（GAF）、数字疼痛评分量表（NPRS）和变化总体评定量表（GRC）。通过检验预先设定的假设来评估阿拉伯语版DASH的反应性。使用受试者工作特征方法（MIC）和预测建模方法（MIC）确定改善的MIC。正如所假设的，阿拉伯语版DASH的变化与GAF的变化（r = 0.69）、NPRS的变化（r = 0.68）和GRC的变化（r = 0.73）呈显著正相关。与我们的假设一致，DASH变化分数可用于区分改善的参与者和未改善的参与者（受试者工作特征曲线下面积 = 0.87），并且在改善的患者中显示出较大的变化幅度（效应大小 = 1.53，标准化反应均值 = 1.42）。所有预先设定的假设均得到结果支持。阿拉伯语版DASH的MIC和MIC估计分别为14.22和14.85。DASH变化与基线分数之间的交互作用不是状态（改善与未改善）的显著预测因素（ = 0.75），表明DASH的MIC不依赖于基线。阿拉伯语版DASH表现出足够的反应性，支持了阿拉伯语版DASH能够检测上肢功能随时间变化的观点。使用预测建模和ROC方法估计时，阿拉伯语版DASH的MIC值相似，且MIC不依赖于基线状态。
