背景：选择最佳的患者报告结局（PRO）工具对提高医疗保健质量至关重要。本研究的目的是比较三个PRO测量的可靠性，反应性和效率：足踝能力测量-日常生活活动分量表方法：采用FAAM_ADL、FFI-5 pt、PROMIS身体功能计算机化适应性测试（PF CAT）对30例患者进行了功能评定。数据来自AOFAS国家矫形足踝研究网络（OFAR）的10个临床站点，来自311名因足部或踝关节疾病接受择期手术的患者。患者在术前访视和术后6个月时接受FAAM_ADL、FFI-5 pt和PF CAT。使用Rasch模型评价可靠性。反应性采用配对样本t检验计算，效率记录为完成仪器的秒数。结果：三种仪器的可靠性相似。FAAM_ADL、FFI-5 pt和PF CAT的项目信度均为0.99。FAAM_ADL、FFI-5 pt和PF CAT的Pearson信度分别为0.95、0.93和0.96。患者平均完成FAAM_ADL 179秒，FFI-5 pt 194秒，PF CAT 44秒（P
Background: Selecting optimal patient-reported outcome (PRO) instruments is critical to improving the quality of health care. The purpose of this study was to compare the reliability, responsiveness, and efficiency of three PRO measures: the Foot and Ankle Ability Measure-Activity of Daily Living subscale (FAAM_ADL), the Foot Function Index 5-point verbal rating scale (FFI-5pt), and the PROMIS Physical Function computerized adaptive test (PF CAT).Methods: Data were aggregated from 10 clinical sites in the AOFAS's National Orthopaedic Foot and Ankle Research (OFAR) Network from 311 patients who underwent elective surgery for a disorder of the foot or ankle. Patients were administered the FAAM_ADL, FFI-5pt, and PF CAT at their preoperative visit and at 6 months after surgery. Reliabilities were evaluated using a Rasch model. Responsiveness was calculated using paired samples t test and efficiency was recorded as number of seconds to complete the instrument.Results: Similar reliabilities were found for the three instruments. Item reliabilities for FAAM_ADL, FFI-5pt, and PF CAT were all.99. Pearson reliabilities for FAAM_ADL, FFI-5pt, and PF CAT were.95,.93, and.96, respectively. On average, patients completed the FAAM_ADL in 179 seconds, the FFI-5pt in 194 seconds, and the PF CAT in 44 seconds, (P
