Cross-Cultural Adaptation and Validation of the Turkish Version of the International Hip Outcome Tool – 12

Özet

Objectives: The present study aims to conduct a translation and transcultural adaptation of the International Hip Outcome Tool –12 (IHOT-12) into Turkish and evaluate the psychometric characteristics of the Turkish version of IHOT-12 (IHOT-12-TR) for validityand reliability in Turkish patients with hip joint disorders.Methods: Following the translation and transcultural adaptation procedures, 109 patients completed the IHOT-12-TR and WesternOntario and McMaster Universities Osteoarthritis Index (WOMAC) scale. The retest was completed by 40 patients approximatelyone week after the initial assessments. The psychometric properties of the questionnaire were tested.Results: Cronbach's alpha of 0.927 revealed the internal consistency to be highly satisfactory. The overall Interclass coefficient (ICC)between test and retest was 0.927 (p<0.001). The correlation between IHOT-12-TR and WOMAC scores was strong and statisticallysignificant (r=0.815, p<0.001). The explanatory factor analyses revealed that IHOT-12-TR had a single factor structure, explaining61.9% of the total variance. There was no floor or ceiling effect on the items and overall scale scores.Conclusion: The results of the analyses in this study demonstrated that the Turkish version of the IHOT- 12 scale, the IHOT-12-TR, isa valid and reliable tool to evaluate the functionality of patients with hip pathologies
