BACKGROUND AND PURPOSE To determine whether the Hip disability and Osteoarthritis Outcome Score-Physical function Short-form (HOOS-PS) is able to appropriately evaluate physical function in revision hip arthroplasty patients, this study assesses psychometric properties of the Dutch HOOS-PS in this patient population. PATIENTS AND METHODS We assessed psychometric properties of the HOOS-PS following the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria. Content validity, including comprehensibility, comprehensiveness, and relevance of the items, was assessed using cognitive debriefing interviews in hip revision patients (n = 8) and orthopedic surgeons specialized in revision surgery (n = 7). Construct validity, responsiveness, and interpretability (floor/ceiling effects) were assessed in revision hip arthroplasty patients (baseline n = 136, follow-up n = 67). We formulated hypotheses a priori to assess construct validity and responsiveness using the EuroQol 5-Dimensions Health Questionnaire, Numeric Rating scale for pain, and Oxford Hip Score as comparators. All questionnaires were measured at baseline and 1 year postoperatively. RESULTS We found insufficient content validity of the HOOS-PS, as relevance and comprehensibility of the items scored < 85% on the COSMIN criteria for revision hip arthroplasty patients. Construct validity was sufficient as all hypotheses were confirmed (≥ 75% COSMIN criteria). Interpretability was sufficient (< 15% COSMIN criteria) and responsiveness was insufficient (< 75% COSMIN criteria). INTERPRETATION The Dutch HOOS-PS is not able to sufficiently evaluate physical function in revision hip arthroplasty patients. Minor changes in the items are needed for the HOOS-PS to become sufficiently content valid, because the HOOS-PS lacks relevant items and comprehensiveness.

HOOS-PS 在全髋关节翻修术中的测量特性：对 136 名翻修髋关节置换术患者的有效性、可解释性和反应性的验证研究。

背景和目的 为确定髋关节残疾和骨关节炎结果评分-身体功能简表 (HOOS-PS) 是否能够适当评估翻修髋关节置换术患者的身体功能，本研究评估了荷兰 HOOS-PS 在本研究中的心理测量特性患者群体。患者和方法 我们根据基于共识的健康测量仪器选择标准 (COSMIN) 标准评估了 HOOS-PS 的心理测量特性。内容有效性，包括项目的可理解性、全面性和相关性，通过对髋关节翻修患者 (n = 8) 和专门从事翻修手术的整形外科医生 (n = 7) 的认知汇报访谈进行评估。建构有效性、反应性、和可解释性（地板/天花板效应）在翻修髋关节置换术患者中进行了评估（基线 n = 136，随访 n = 67）。我们先验地制定了假设，以使用 EuroQol 5 维健康问卷、疼痛数字评定量表和牛津髋关节评分作为比较对象来评估结构有效性和反应性。所有问卷均在基线和术后 1 年进行测量。结果 我们发现 HOOS-PS 的内容有效性不足，因为根据 COSMIN 髋关节置换术患者标准，项目的相关性和可理解性得分 < 85%。构造有效性是足够的，因为所有假设都得到证实（≥ 75% COSMIN 标准）。可解释性足够（< 15% COSMIN 标准）和响应能力不足（< 75% COSMIN 标准）。解释 荷兰 HOOS-PS 无法充分评估髋关节置换术患者的身体功能。HOOS-PS 需要对项目进行微小的更改才能使内容足够有效，因为 HOOS-PS 缺乏相关项目和全面性。
