Abstract

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.
