Responsiveness to change is an important psychometric property of an outcome instrument. Assessment of health-related quality of life (HRQoL) is critical to outcome assessment after total joint replacement, a surgery aimed at improving pain, function and HRQoL of the patients undergoing these procedures. In a recent study, Shi et al. examined the responsiveness to change of various subscales of two instruments, physician-administered Harris Hip Score and patient self-administered Short Form-36 (SF-36), 6 months after revision total hip arthroplasty. The responsiveness statistics for both scales were reasonable, higher for Harris Hip Score than SF-36. This is the first study to examine responsiveness of these instruments in revision THA patients in a systematic fashion.
变化反应性是一种结果工具的重要心理计量学特性。在全关节置换术后的结果评估中，健康相关生活质量（HRQoL）的评估至关重要，这是一种旨在改善接受这些手术的患者的疼痛、功能和 HRQoL 的手术。在最近的一项研究中，Shi 等人研究了两种工具（医生管理的 Harris 髋关节评分和患者自我管理的 Short Form-36（SF-36））的各个分量表在翻修全髋关节置换术后 6 个月时的变化反应性。两种量表的反应性统计数据都合理，Harris 髋关节评分的反应性高于 SF-36。这是第一项系统研究这些工具在翻修 THA 患者中的反应性的研究。
