This study explored the psychometric properties of the modified Harris Hip Score-Greek version (mHHS-Gr) as a patient-reported outcome (PRO) measure in osteoarthritic hip patients.
Internal consistency, test-retest reliability and reproducibility were evaluated in 90 patients aged >55 years. Construct validity was tested against Greek versions of the Lower Extremity Functional Scale (LEFS-Greek) and WOMAC Index (WOMAC-Gr), and the Timed Up and Go (TUG) and 9-stairs-ascend/descend (9S-A/D) tests. Known-groups validity was examined using TUG score (cut-off 13.5 s) as an estimate variable. Responsiveness was examined before and 4 weeks after direct anterior minimal invasive surgery.
Internal consistency was moderate (Cronbach's = 0.614, < 0.001). Test-retest reliability was excellent (ICC = 0.881, 95% CI, 0.824-0.920). : Floor and ceiling effects were both 1.1%; measurement error was 3.54 ( < 0.05); minimal important change was lower than minimal detectable change. mHHS-Gr correlated strongly with both LEFS-Greek and WOMAC-Gr (Pearson's 0.801 and -0.783, respectively; < 0.001). The questionnaire's correlations with TUG and 9S-A/D were also significant but moderate (Spearman's : -0.547 and -0.575, respectively; < 0.001). Known-groups validity showed that mHHS-Gr scores were significantly higher in participants with TUG < 13.5 seconds than in those with TUG > 13.5 seconds ( < 0.001). In ROC analysis, the cut-off point of 52.5 yielded sensitivity 81% and specificity 71%. Standardised response mean and Guyatt's responsiveness statistic were greater than 0.8.
mHHS-Gr showed significant moderate to excellent reliability, significant moderate to strong validity properties and excellent responsiveness. Overall, mHHS-Gr could be a reliable and valid PRO measure for assessing patients with osteoarthritis of the hip.
本研究旨在探讨改良 Harris 髋关节评分-希腊版（mHHS-Gr）作为骨关节炎髋关节患者的患者报告结局（PRO）测量工具的心理测量特性。
对 90 名年龄大于 55 岁的患者进行内部一致性、测试-重测信度和可重复性评估。结构效度通过与希腊版下肢功能量表（LEFS-Gr）和 WOMAC 指数（WOMAC-Gr）以及计时起立行走（TUG）和 9 级上下楼梯（9S-A/D）测试进行检验。使用 TUG 评分（13.5 秒作为估计变量）作为效标变量来评估已知组间的有效性。在直接前路微创术前和术后 4 周评估反应性。
内部一致性为中度（Cronbach's = 0.614， < 0.001）。测试-重测信度为优（ICC = 0.881，95%CI，0.824-0.920）。地板和天花板效应均为 1.1%；测量误差为 3.54（ < 0.05）；最小临床重要差异低于最小可检测差异。mHHS-Gr 与 LEFS-Gr 和 WOMAC-Gr 均高度相关（Pearson's 0.801 和 -0.783，分别； < 0.001）。问卷与 TUG 和 9S-A/D 的相关性也具有显著意义，但为中度（Spearman's -0.547 和 -0.575，分别； < 0.001）。已知组间的有效性表明，TUG < 13.5 秒的参与者的 mHHS-Gr 评分显著高于 TUG > 13.5 秒的参与者（ < 0.001）。在 ROC 分析中，52.5 的截断点产生了 81%的敏感性和 71%的特异性。标准化反应均值和 Guyatt 的反应性统计量大于 0.8。
mHHS-Gr 显示出显著的中度到优的信度、显著的中度到强的有效性和极好的反应性。总的来说，mHHS-Gr 可以作为一种可靠和有效的 PRO 测量工具，用于评估髋关节骨关节炎患者。
