The Hospital for Special Surgery Hip Replacement Expectations Survey (HSS-THRES) is used in many countries to determine patient expectations before surgery. This study aimed to assess the reliability and validity of the Japanese version of HSS-THRES.
A total of 134 patients scheduled for total hip arthroplasty (THA) underwent a self-administered preoperative survey questionnaire. Patient's expectation and quality of life (QOL) were measured using the Japanese version of HSS-THRES, overall expectations for THA, Oxford hip score (OHS), and EuroQol-5D (EQ-5D). Some patients completed the Japanese version of HSS-THRES and the overall expectations for THA after a ten-day interval. Cross-cultural adaptation was validated by an expert committee comprising health professionals, a methodologist, language experts, and orthopedic specialists. The internal consistency was evaluated by the Cronbach α coefficient. The test-retest reliability was examined using the intraclass coefficient correlation (ICC) and the Bland and Altman analysis. To test the construct validity, nine priori hypotheses were tested by correlation analysis between the Japanese version of HSS-THRES and two QOL scales, and by examining the association with demographic variables.
A total of 116 patients completed four scales. Patients were predominantly female (75.9%), with an average age of 62.2 ± 11.7. In the cross-cultural adaptation, all patients responded to the questionnaire without problems. The Japanese version of HSS-THRES showed good internal consistency (Cronbach α: 0.9). ICC was 0.94 and Bland-Altman analysis indicated no bias. The correlation between Japanese HSS-THRES and overall expectations for THA was high (r = 0.67). Similarly, the correlation with the OHS was higher than that with EQ-5D. A total of 77.8% of the hypotheses were confirmed.
The Japanese version of HSS-THRES showed good cultural acceptability, high reliability, and validity to evaluate preoperative expectations for THA patients.
特殊外科医院髋关节置换期望调查（HSS - THRES）在许多国家用于确定患者术前的期望。本研究旨在评估日语版HSS - THRES的信度和效度。
共有134例计划行全髋关节置换术（THA）的患者进行了术前自填式调查问卷。使用日语版HSS - THRES、对THA的总体期望、牛津髋关节评分（OHS）和欧洲五维度健康量表（EQ - 5D）来测量患者的期望和生活质量（QOL）。部分患者在间隔十天后完成了日语版HSS - THRES和对THA的总体期望。跨文化适应性由包括健康专业人员、方法学家、语言专家和骨科专家的专家委员会进行验证。通过Cronbach α系数评估内部一致性。使用组内相关系数（ICC）和布兰德 - 奥特曼分析来检验重测信度。为检验结构效度，通过日语版HSS - THRES与两个生活质量量表之间的相关性分析以及与人口统计学变量的关联检验，对九个先验假设进行了检验。
共有116例患者完成了四个量表。患者以女性为主（75.9%），平均年龄为62.2±11.7岁。在跨文化适应性方面，所有患者完成问卷均无问题。日语版HSS - THRES显示出良好的内部一致性（Cronbach α：0.9）。ICC为0.94，布兰德 - 奥特曼分析表明无偏差。日语版HSS - THRES与对THA的总体期望之间的相关性较高（r = 0.67）。同样，与OHS的相关性高于与EQ - 5D的相关性。共有77.8%的假设得到证实。
日语版HSS - THRES在评估THA患者术前期望方面显示出良好的文化可接受性、高信度和效度。
