Abstract

Background

Patient-reported outcome (PRO) measures are essential for evaluating disease-related quality of life. The International Hip Outcome Tool 12 (iHOT12) assesses various aspects of hip-related symptoms, function, sports participation, and social limitations. This study aimed to adapt and validate an Italian version of the iHOT12 according to COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines.

Materials and methods

A multicenter observational cohort study was conducted to translate and validate the iHOT-12 into Italian (iHOT-12-ita) and assess its psychometric properties. Following international guidelines, we translated and culturally adapted the iHOT-12-ita. Patients with hip pain included in the study completed the iHOT-12-ita and mHHS-ita questionnaires at three timepoints: initial consultation (T0), 10–20 days later (T1), and at least 2 months after treatment (T2): hip injection, hip arthroscopy or total hip replacement. The evaluation of the iHOT-12-ita psychometric properties was conducted following the COSMIN checklist, assessing its reliability, responsiveness, interpretability, and acceptability.

Results

Between May 2019 to September 2022, 104 patients were included, from two tertiary hip surgery referral center clinics, they completed both questionnaires and were available for data analysis. The psychometric evaluations revealed robust test–retest reliability on 27 patients at T1, with a Lin coefficient of 0.709 [95% confidence interval (CI) 0.553–0.888] and a high Pearson correlation coefficient of 0.745. At T2 after treatment, there was significant responsiveness (p < 0.001, n = 72), with excellent correlation observed between the iHOT-12-Ita and mHHS-Ita questionnaires (pwcorr = 0.7971). All predefined hypotheses were confirmed.

Conclusions

The Italian iHOT-12-ita proved reliable, valid, and responsive in assessing hip disease-related quality of life. Its implementation in routine clinical practice and research can enhance patient care and research quality in hip preservation surgery for the Italian orthopedic community.

Level of evidence: II.
