The Hip Outcome Score (HOS) is a questionnaire commonly used to assess the clinical outcome of patients after hip arthroscopy. However, a Korean version of the HOS is not available. The aim of this study was to translate and adapt the HOS questionnaire into the Korean language and then assess the psychometric properties of this instrument.
Translation and transcultural adaptation of the HOS into Korean (HOS-K) was performed in accordance with the international recommendations. Sixty patients (mean age 38.4 years) planning hip arthroscopy participated in evaluating the psychometric properties of the HOS-K. Psychometric analyses consisted of assessing for the following: (1) floor/ceiling effects, (2) internal consistency using Cronbach's alpha, (3) test-retest reliability over 2-3 weeks with intraclass correlation coefficient (ICC), (4) convergent validity by correlation with the SF-36 and Hip disability and Osteoarthritis Outcome Score (HOOS), (5) construct validity by assessing for a difference in HOS-K scores based on a rating of hip function, and (6) responsiveness with a change in score over a 6-month period.
The English version of the HOS was translated and adapted to Korean without notable discrepancies. The HOS-K scores were reliable with ICC of 0.946 for the activities of daily living (ADL) subscale and 0.929 for the sports subscale. Internal consistency was confirmed by Cronbach's alpha >0.90 for both subscales. Both subscales had a strong correlation to the five subscales of SF-36, except the general health subscale. The ADL subscale showed strong correlations with all the subscales of the HOOS, and sports subscale showed strong correlations with all subscales of the HOOS, except the symptom subscales of HOOS. The HOS-K also demonstrated evidence for responsiveness without floor and ceiling effects.
The HOS-K can be recommended as an outcome instrument in hip arthroscopy for Korean-speaking individuals. Surgeons can use the HOS-K to evaluate the outcome of hip arthroscopy in Korea.

髋关节结局评分（HOS）是一种常用于评估髋关节镜检查术后患者临床结局的问卷。然而，目前尚无韩语版的HOS。本研究的目的是将HOS问卷翻译成韩语并进行改编，然后评估该工具的心理测量学特性。
按照国际推荐方法将HOS翻译成韩语（HOS-K）并进行跨文化调适。60例计划接受髋关节镜检查的患者（平均年龄38.4岁）参与评估HOS-K的心理测量学特性。心理测量学分析包括评估以下内容：（1）地板效应/天花板效应；（2）使用Cronbach's α评估内部一致性；（3）通过组内相关系数（ICC）评估2至3周的重测信度；（4）通过与SF-36以及髋关节残疾和骨关节炎结局评分（HOOS）的相关性评估收敛效度；（5）通过根据髋关节功能评级评估HOS-K评分差异来评估结构效度；（6）评估6个月期间评分变化的反应度。
HOS的英文版被翻译成韩语并进行了改编，没有明显差异。HOS-K评分具有可靠性，日常生活活动（ADL）子量表的ICC为0.946，运动子量表的ICC为0.929。两个子量表的Cronbach's α均>0.90，证实了内部一致性。除一般健康子量表外，两个子量表与SF-36的五个子量表均有强相关性。ADL子量表与HOOS的所有子量表均有强相关性，运动子量表与HOOS的所有子量表（除HOOS的症状子量表外）均有强相关性。HOS-K也显示出有反应度的证据，且无地板效应和天花板效应。
HOS-K可推荐作为韩语使用者髋关节镜检查的结局评估工具。外科医生可使用HOS-K评估韩国髋关节镜检查的结果。
