Due to no existing data, we aimed to derive evidence to support test-retest reliability for the Health Assessment Questionnaire-Disability Index (HAQ-DI) and 36-item Short Form Health Survey physical functioning domain (SF-36 PF) in psoriatic arthritis (PsA).
We identified datasets that collected relevant data for test-retest reliability for HAQ-DI and SF-36 PF, and evaluated them using Outcome Measures in Rheumatology (OMERACT) Filter 2.1 methodology. We calculated intraclass correlation coefficients (ICC) as a measure of test-retest reliability. We then conducted a quality assessment and evaluated the adequacy of test-retest reliability performance.
Two datasets were identified for HAQ-DI and 1 for SF-36 PF in PsA. The quality of the datasets was good. The ICCs for HAQ-DI were good and excellent in study 1 (0.90, 95% CI 0.79-0.95) and study 2 (0.94, 95% CI 0.89-0.97). The ICC for SF-36 PF was excellent (0.96, 95% CI 0.92-0.98). The performance of test-retest reliability for both instruments was judged to be adequate.
The new data derived support good and reasonable test-retest reliability for HAQ-DI and SF-36 PF in PsA.
由于缺乏现有数据，我们旨在为银屑病关节炎（PsA）患者的健康评估问卷残疾指数（HAQ-DI）和 36 项简短健康调查问卷生理功能领域（SF-36 PF）的重测信度提供证据。
我们确定了收集 HAQ-DI 和 SF-36 PF 重测信度相关数据的数据集，并使用风湿病结局测量（OMERACT）筛选 2.1 方法对其进行评估。我们计算了用于评估重测信度的组内相关系数（ICC）。然后我们进行了质量评估，并评估了重测信度性能的充分性。
确定了 2 个用于 HAQ-DI 的数据集和 1 个用于 PsA 中的 SF-36 PF 的数据集。数据集的质量良好。研究 1（0.90，95%置信区间 0.79-0.95）和研究 2（0.94，95%置信区间 0.89-0.97）中 HAQ-DI 的 ICC 值良好且优秀。SF-36 PF 的 ICC 值为优秀（0.96，95%置信区间 0.92-0.98）。两种仪器的重测信度性能均被认为是充分的。
新获得的数据支持在 PsA 中 HAQ-DI 和 SF-36 PF 具有良好和合理的重测信度。
