Purpose:

(1) Translate and culturally adapt the iHOT12 into Hebrew using established guidelines. (2) To test the new Hebrew version for validity, and (3) reliability.



Methods:

The iHOT12 was translated and culturally adapted from English to Hebrew (iHOT12-H) according to the COSAMIN guidelines. For validity, the iHOT12-H and Western Ontario and McMaster universities osteoarthritis index (WOMAC) were completed by 200 patients with hip pathology. Exploratory factor analysis was used to assess structural validity. Subsequently, 51 patients repeated the iHOT12-H within a 2-week interval. Intraclass Correlation Coefficient (ICC), Cronbach alpha, and Standard Error of Measurement (SEM) were calculated to assess reliability. 



Results:

Construct validity: iHOT12-H correlated strongly to the WOMAC scores (r=-0.82, P0.001, Spearman). Factor analysis revealed a two-factor structure. Cronbach's alpha was 0.953 confirming internal consistency to be highly satisfactory. Test-retest correlation of the iHOT12-H was excellent with an ICC=0.956 (95% CI 0.924-0.974). There was no floor or ceiling effect. 


Conclusion(s):

The iHOT12 Hebrew version has excellent reliability, good construct validity and can be used as a measurement tool for physical functioning and quality of life in young, physically active patients with hip pathology. 


Implications:

This study will serve Israeli researchers in evaluating treatment effectiveness for these patients. Moreover, it will also enable multinational cooperation in the study of hip pathology.
