Transcultural adaptation and testing of psychometric properties of the Korean version of the Oxford hip score

The Oxford hip score (OHS) is one of the most widely used scoring systems to assess clinical outcome for patients with total hip arthroplasty (THA). Few studies have evaluated the OHS in non-Western patients with other cultural backgrounds, particularly Asians. Translation and transcultural adaptation of the OHS into the Korean was performed in accordance with international recommendations and the psychometric properties were tested. For testing the psychometric properties, 150 patients (mean age, 51 years) planning THA were recruited, and floor/ceiling effects and internal consistency were determined. Test–retest reliability and convergent validity were assessed by correlation with the SF-36, HOOS, and VAS for pain for 122, and responsiveness was evaluated for 100. The Korean version had satisfactory internal consistency, test–retest reliability, convergent validity, and responsiveness without floor and ceiling effects. This study shows that the OHS developed in the West, with transcultural adaptation, is relevant for the patients undergoing THA in Korea.
