    ObjectiveTranslation and transcultural adaptation of the Hip Disability and Osteoarthritis Outcome Score (HOOS LK 2.0) into Korean language was performed, followed by test of psychometric properties.DesignA Korean version of the HOOS was produced according to internationally recommended guidelines, which included forward translation, reconciliation, back translation, harmonization, cognitive debriefing and proof reading. The psychometric properties including reliability and validity were evaluated. The reliability, including the internal consistency and test-retest reliability, was then evaluated in a hip osteoarthritis population (OA group, n=75). The validity, including the convergent validity was assessed comparing HOOS with the Short Form-36 (SF-36) and pain on a visual analogue scale (VAS) scale. Responsiveness was evaluated in a population scheduled for total hip arthroplasty (THA group, n=35).ResultsAll subscales of the HOOS showed satisfactory internal consistency (Cronbach's alpha>0.7) without floor and ceiling effects. Intraclass correlation coefficient (ICC) spanned from 0.78 to 0.93. In terms of convergent validity, Activity of Daily Living (ADL) subscale showed the strongest correlations with Physical Function (PF) (r=0.801) and Bodily Pain (BP) (r=0.810) in the subscales of SF-36. For responsiveness, all HOOS subscale scores improved significantly (P<0.05) postoperatively.ConclusionsThe Korean version of HOOS showed satisfactory internal consistency, test-retest reliability, convergent validity, and responsiveness. This study shows that the HOOS questionnaire developed in West is, with transcultural adaptation, relevant for use among patients in East Asia.Copyright © 2011 Osteoarthritis Research Society International.
