Reliability and validity of the cross-culturally adapted German Oxford hip score

Clin Orthop Relat Res. 2009 Apr;467(4):952-7. doi: 10.1007/s11999-008-0457-3. Epub 2008 Aug 26.


There is currently no German version of the Oxford hip score. Therefore we sought to cross-culturally adapt and validate the Oxford hip score for use with German-speaking patients (OHS-D) with osteoarthritis of the hip using a forward-backward translation procedure. We then assessed the new score in 105 consecutive patients (mean age, 63.4 years; 48 women) undergoing THA. We specifically determined: the number of fully completed questionnaires, reliability, concurrent validity by correlation with the WOMAC, Harris hip score, and SF-12, and distribution of floor and ceiling effects. We received 96.6% fully completed questionnaires. An intraclass correlation coefficient of 0.90 and Cronbach's alpha of 0.87 suggested the OHS-D was reliable. Correlation coefficients between the OHS-D and the WOMAC total score, pain subscale, stiffness subscale, and physical function subscale were 0.82, 0.70, 0.68, and 0.82, respectively. OHS-D correlated with the Harris hip score (r = 0.63) and the physical component scale of the SF-12 (r = 0.58). We observed no ceiling or floor effects. The OHS-D appeared a reliable and valid measurement tool for assessing pain and disability with German-speaking patients with hip osteoarthritis.
