The main aim of this study was to analyze correlations between individual international hip outcome tool 12 (iHOT-12) items and overall iHOT-12 score within and across timepoints. A retrospective multicenter hip arthroscopy registry was queried for patients from January 2014 to October 2023 with completed iHOT-12 reports. Pearson coefficient analysis was used to identify correlations between individual iHOT-12 items and overall iHOT-12 score at each timepoint and between preoperative individual iHOT-12 items and postoperative overall iHOT-12 scores. Validity, reliability, and responsiveness of the iHOT-12 were analyzed at each timepoint. Within timepoints, correlations ranged in strength from fair (preoperative maintain fitness level, = 0.52, < .00001) to excellent (5-year hip pain after activity, = 0.93, < .00001). Correlations increased in strength over time. Across timepoints, correlations ranged in strength from no correlation (2-year maintain fitness level, = -0.001, = 0.94) to poor (6-month pushing or lifting heavy objects, = 0.31, < .00001). Correlations decreased in strength over time. No ceiling or floor effects were exhibited. The Cronbach alpha for the baseline, 6-month, 1-year, 2-year, and 5-year timepoints were 0.87, 0.96, 0.95, 0.96, and 0.97, respectively. Cohen's values at 6 months, 1 year, 2 years, and 5 years were 1.19, 1.43, 1.71, and 1.58, respectively. Within timepoints, hip pain after activity had the strongest correlations to overall iHOT-12 score. Across timepoints, correlations between preoperative individual iHOT-12 items and postoperative overall iHOT-12 score were poor and weakened over time, suggesting similar long-term postoperative iHOT-12 scores among both high- and low-scoring preoperative patients. The iHOT-12 demonstrated good validity, reliability, and responsiveness at all timepoints.
本研究的主要目的是分析国际髋关节结果工具12项（iHOT - 12）各条目与不同时间点及跨时间点的iHOT - 12总分之间的相关性。对2014年1月至2023年10月期间完成iHOT - 12报告的患者的回顾性多中心髋关节镜登记资料进行查询。采用Pearson系数分析来确定每个时间点iHOT - 12各条目与iHOT - 12总分之间以及术前iHOT - 12各条目与术后iHOT - 12总分之间的相关性。在每个时间点分析iHOT - 12的效度、信度和反应度。在各时间点内，相关性强度范围从中等（术前维持健康水平，r = 0.52，p <.00001）到极好（活动后5年髋关节疼痛，r = 0.93，p <.00001）。相关性强度随时间增加。跨时间点，相关性强度范围从无相关性（2年维持健康水平，r = -0.001，p = 0.94）到较差（6个月推或提重物，r = 0.31，p <.00001）。相关性强度随时间降低。未表现出天花板效应或地板效应。基线、6个月、1年、2年和5年时间点的Cronbach α系数分别为0.87、0.96、0.95、0.96和0.97。6个月、1年、2年和5年时的Cohen's d值分别为1.19、1.43、1.71和1.58。在各时间点内，活动后髋关节疼痛与iHOT - 12总分的相关性最强。跨时间点，术前iHOT - 12各条目与术后iHOT - 12总分之间的相关性较差且随时间减弱，提示术前高分和低分患者术后长期iHOT - 12评分相似。iHOT - 12在所有时间点均表现出良好的效度、信度和反应度。
