Translation, cross-cultural adaptation and validation of the Slovenian version of Harris Hip Score

INTRODUCTION: The Harris Hip Score is the most widely used outcome measure for the assessment of hip pathologies. An official Slovenian version has not been culturally adapted and validated. The aim of this study was to create a Slovenian valid and reliable version of the HHS. MATERIALS AND METHOD: The HHS was translated and modified in Slovenian. The measurement properties of the Slovenian HHS were tested in 42 patients suffering from different hip pathologies. Reliability, responsiveness, construct validity, convergent/divergent validity and content validity of the Slovenian version of the HHS were tested. RESULTS: Only minor adaptation was required in the translation process. The internal consistency of the HHS expressed by Cronbach’s alpha was 0.94. The test–retest reliability expressed by the intraclass correlation coefficient was 0.983. The correlations of the HHS scale with the WOMAC scale (r = − 0.877) and the VAS scale (r = − 0.717) were statistically significant. The highest correlation between the HHS and SF-36 was with the General Health dimension (r = 0.61). while the lowest correlation was with the SF-36 Mental Health dimension (r = 0.43). MDC95% was 10.1. No floor or ceiling effects were found. CONCLUSION: Slovenian version of HHS seems to has an acceptable level of reliability and validity. Slovenian HHS is short, comprehensible and easy to administer and interpret. TRIAL REGISTRATION: Approved by the Slovenian National Medical Ethics Committee (0120-46/2019/19).
