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 validity and reliability in Turkish patients with hip joint disorders.
Methods: Following the translation and transcultural adaptation procedures, 109 patients completed the IHOT-12-TR and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale. The retest was completed by 40 patients approximately one 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 statistically significant (r=0.815, p<0.001). The explanatory factor analyses revealed that IHOT-12-TR had a single factor structure, explaining 61.9% 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, is a valid and reliable tool to evaluate the functionality of patients with hip pathologies. (SETB-2020-09-166)
