BACKGROUND/AIMS: The most reliable patient-reported outcomes (PROs) for people with femoroacetabular impingement (FAI) is unknown because there have been no direct comparisons of questionnaires. Thus, the aim was to evaluate the test-retest reliability of six existing PROs in a single cohort of young active people with hip/groin pain consistent with a clinical diagnosis of FAI.
Young adults with clinical FAI completed six PRO questionnaires on two occasions, 1-2 weeks apart. The PROs were modified Harris Hip Score, Hip dysfunction and Osteoarthritis Score, Hip Outcome Score, Non-Arthritic Hip Score, International Hip Outcome Tool, Copenhagen Hip and Groin Outcome Score.
30 young adults (mean age 24 years, SD 4 years, range 18-30 years; 15 men) with stable symptoms participated. Intraclass correlation coefficient(3,1) values ranged from 0.73 to 0.93 (95% CI 0.38 to 0.98) indicating that most questionnaires reached minimal reliability benchmarks. Measurement error at the individual level was quite large for most questionnaires (minimal detectable change (MDC95) 12.4-35.6, 95% CI 8.7 to 54.0). In contrast, measurement error at the group level was quite small for most questionnaires (MDC95 2.2-7.3, 95% CI 1.6 to 11).
The majority of the questionnaires were reliable and precise enough for use at the group level. Samples of only 23-30 individuals were required to achieve acceptable measurement variation at the group level. Further direct comparisons of these questionnaires are required to assess other measurement properties such as validity, responsiveness and meaningful change in young people with FAI.
背景/目的：对于患有股骨髋臼撞击症（FAI）的患者，最可靠的患者报告结局（PROs）尚不清楚，因为尚未对问卷进行直接比较。因此，本研究旨在评估在髋关节/腹股沟疼痛与临床诊断为 FAI 一致的年轻活跃人群中，对 6 种现有 PRO 进行单次队列测试-再测试可靠性。
临床诊断为 FAI 的年轻成年人在两次就诊时完成了 6 项 PRO 问卷，两次就诊间隔 1-2 周。PRO 包括改良 Harris 髋关节评分、髋关节功能障碍和骨关节炎评分、髋关节结局评分、非关节炎髋关节评分、国际髋关节结局工具、哥本哈根髋关节和腹股沟结局评分。
30 名年轻成年人（平均年龄 24 岁，标准差 4 岁，范围 18-30 岁；15 名男性）稳定症状参与了研究。组内相关系数（3,1）值范围为 0.73 至 0.93（95%CI 0.38 至 0.98），表明大多数问卷达到了最小可靠性基准。对于大多数问卷，个体水平的测量误差相当大（最小可检测变化（MDC95）为 12.4-35.6，95%CI 8.7 至 54.0）。相比之下，对于大多数问卷，组内水平的测量误差相当小（MDC95 为 2.2-7.3，95%CI 1.6 至 11）。
大多数问卷在组内水平上是可靠且精确的。仅需要 23-30 名个体的样本即可在组内水平上获得可接受的测量变异性。还需要对这些问卷进行进一步的直接比较，以评估在患有 FAI 的年轻人中其他测量特性，如有效性、反应性和有意义的变化。
