膝关节疾病患者的临床研究报告应常规包括其活动水平，以便能够比较治疗组并具有普遍性。本研究的目的是开发和评估一种新的评定量表来测量患者的活动水平。我们评估的可靠性管理规模40名受试者在2个不同的场合，我一周的时间间隔。有效性进行了评估，通过比较新的规模与其他工具，使用活动水平量表（并行结构效度）的活动评级，并通过相关的新规模与年龄（发散效度）的分数。患者很容易理解量表，并能够在1分钟内完成。信度高（组内相关系数0.97）。该量表也与现有的活动评定量表相关良好：辛辛那提评分的斯皮尔曼相关系数为0.67; Tegner量表为0.66;丹尼尔量表为0.52。活动得分与年龄呈显著负相关（P = 0.002），表明不同的效度。该工具将促进结果的普遍性，并允许在运动医学结果研究中更准确地比较患者群体。
Reports of clinical studies of patients with knee disorders should routinely include their activity levels to enable comparison of treatment groups and to allow generalizability. The goal of this study was to develop and evaluate a new rating scale to measure activity levels of patients. We assessed reliability by administering the scale to 40 subjects on 2 separate occasions, I week apart. Validity was evaluated by comparing the activity rating on the new scale with that from other instruments that use activity level scales (concurrent construct validity) and also by correlating the score on the new scale with age (divergent validity). Patients easily understood the scale and were able to complete it in 1 minute. The reliability was high (intraclass correlation coefficient, 0.97). The scale also correlated well with existing activity rating scales: Spearman correlation coefficient for Cincinnati score, 0.67; for Tegner scale, 0.66; for Daniel scale, 0.52. The activity score was significantly inversely correlated with age (P = 0.002), indicating divergent validity. This instrument will facilitate generalizability of results and allow more accurate comparisons among patient groups in outcomes research in sports medicine.
