The ACL-Return to Sport after Injury (ACL-RSI) and Injury-Psychological Readiness to Return to Sport (I-PRRS) scales were developed to assess psychological factors associated with return to sports. Validity and reliability have been determined. The aim of this study was to investigate the responsiveness of the Dutch ACL-RSI and I-PRRS. Seventy patients with ACL reconstruction completed both scales twice 2 months apart, plus a Global Rating of Change (GRC) questionnaire. Distribution and logistic regression-based methods were used to study responsiveness. The Standardized Response Mean (SRM) for the ACL-RSI was 0.3 and for the I-PRRS 0.1, indicating low responsiveness. The minimally important change (MIC) for ACL-RSI was 2.6 and for the I-PRRS 0.9. Since the standard error of measurement (SEM) and smallest detectable change (SDC) were larger than MIC in individual patients, it does not seem possible to distinguish minimally important changes from measurement error in individual patients with either scale. At the group level responsiveness seemed sufficient; hence, both scales can be used to investigate the effectiveness of an intervention at the group level. Both scales can also be used in cross-sectional research and in clinical practice as screening instruments to identify patients at risk of not returning to sports.
ACL 损伤后重返运动（ACL-RSI）和损伤-重返运动心理准备（I-PRRS）量表旨在评估与重返运动相关的心理因素。其有效性和可靠性已得到确定。本研究旨在探讨荷兰 ACL-RSI 和 I-PRRS 的反应能力。70 名 ACL 重建患者在 2 个月内两次完成了这两个量表，外加一个整体变化评分（GRC）问卷。使用分布和基于逻辑回归的方法来研究反应能力。ACL-RSI 的标准化反应均值（SRM）为 0.3，I-PRRS 为 0.1，表明反应能力较低。ACL-RSI 的最小重要变化（MIC）为 2.6，I-PRRS 为 0.9。由于测量误差（SEM）和最小可检测变化（SDC）在个体患者中均大于 MIC，因此似乎无法在个体患者中区分最小重要变化和测量误差。在群体水平上，反应能力似乎足够；因此，这两个量表都可用于在群体水平上研究干预措施的效果。在横断面研究和临床实践中，这两个量表也可用作筛选工具，以识别有无法重返运动风险的患者。
