title: Cross-cultural adaptation and validation of the Turkish version of the Hip disability and Osteoarthritis Outcome Score-Physical function Short-form (HOOS-PS).
abstract: The purpose of this study is to adapt the Hip disability and Osteoarthritis Outcome Score-Physical function Short-form (HOOS-PS) to Turkish language and to evaluate the psychometric properties of the Turkish version in patients with primary hip osteoarthritis. After the translation from the source language (English) to the target language (Turkish), synthesis, back translation, revision, and pretest stages were done. Next, 50 patients with primary hip osteoarthritis were asked to fill out the Turkish version of the HOOS-PS two times with one week interval. Internal consistency was tested using the Cronbach's alpha coefficient, and test-retest reliability was assessed by calculating the intra-class correlation coefficient (ICC). Construct validity was investigated by comparing the results of the HOOS-PS and WOMAC, Lequesne questionnaries using Spearman's rank correlation coefficient. Internal consistency was good with a Cronbach's alpha of 0.778 (>0.7) and ICC was 0.911 (>0.7). Both scores verify that the Turkish HOOS-PS is a reliable tool. Spearman's rank correlation coefficients between the HOOS-PS and overall WOMAC (r = 0.653), WOMAC physical functions (r = 0.626), WOMAC pain (r = 0.629) subscales, overall Lequesne (r = 0.650), and Lequesne daily living activities (r = 0.620) subscales were high (r > 0.6), and moderate correlations were found between the HOOS-PS and WOMAC stiffness (r = 0.511), Lequesne pain (r = 0.569), and Lequesne-walking distance (r = 0.578) subscales (0.6 > r > 0.2), thus providing proof for the validity of the Turkish form. The Turkish HOOS-PS was found to be reliable and valid for patients with primary hip osteoarthritis.
