Translation, cross‑cultural adaptation and validation of the Slovenian version of Harris Hip Score Petra Josipović1,4* , Metka Moharič2 and Dea Salamon3
Abstract 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). Keywords: Hip, Slovenian, Harris hip score, Translation, Validation Introduction Many outcome measures have been developed for the assessment of hip pathologies, such as the Oxford Hip Score, Nonarthritic Hip Score, Hip and Groin Outcome Score, International Hip Outcome Tool, Hip Outcome Score, Hip Dysfunction and Osteoarthritis Score, and Merle d’Aubigné and Postel score [1–6]. The Harris Hip Score (HHS) is one of the most widely used health related quality of life measures for the assessment of hip *Correspondence: [email protected] 1 Univerza v Ljubljani Medicinska Fakulteta, Vrazov trg 2, Ljubljana, Slovenia Full list of author information is available at the end of the article
pathology [7]. The HHS was developed for the assessment of the results of hip surgery and evaluation of various hip disabilities in an adult population [8]. The HHS is administered by a physician or physiotherapist and presents a scale with the maximum of 100 points, including evaluation of pain, function, deformity and motion [8]. The pain domain measures pain severity and its effect on activities and need for pain medication. The function domain is divided into daily activities (stair use, using public transportation, sitting, and managing shoes and socks) and gait (limp, support needed, and walking distance). The deformity domains observe hip flexion, adduction
