Abstract
BACKGROUND: Movements and lifestyle habits common in Japanese daily life are similar to those in Turkish culture. Therefore, the aim of this study was to adapt the Japanese Orthopedic Association Hip Disease Evaluation Questionnaire (JHEQ), developed by the Japanese Hip Society for hip joint diseases, to the Turkish population and to examine its reliability and validity. METHODS: The study included 134 patients with hip disorders. Intraclass Correlation Coefficient (ICC) and Cronbach's alpha were evaluated for reliability. For construct validity, the relationship between JHEQ and Oxford Hip Score (OHS), International Hip Outcome Tool-12 (IHOT-12) and Short Form-36 (SF-36) was examined by Spearman correlation analysis. RESULTS: The ICC of the total JHEQ score was 0.951 and Cronbach's α was 0.975. The Bland-Altman plot graph revealed good test-retest reliability for the JHEQ. Spearman correlation analysis including the OHS, IHOT-12, and SF-36 subscales showed good correlations with OHS (-0.618), IHOT-12 (0.621), physical function (0.682), social functioning (0.453), bodily pain (0.550), and general health perception (0.424). The value of Minimal Detectable Change (11.64) was higher than the value of Standard Error Measurement (4.20), indicating that the JHEQ has adequate responsiveness. CONCLUSION: The Turkish adaptation of the JHEQ has proven to be a dependable and accurate instrument for assessing hip disease-related outcomes in clinical practice.
