Translation and Cross‑Cultural Adaptation of the International Hip Outcome Tool 12 and 33 into European Portuguese

Introduction: Hip pathologies in young adults have a significant impact on quality of life, affecting physical activities, professional performance and general well‑being. Cultural adaptation of the iHOT‑12 and iHOT‑33 into Portuguese is essential to ensure the accuracy and relevance of these instruments in the Portuguese population. We aimed to translate and culturally adapt the iHOT‑12 and iHOT‑33 questionnaires into European Portuguese, ensuring their validity and reliability. Methods: A rigorous approach to translation and cultural adaptation was followed, including initial translation, back‑translation, review by a committee of experts, pre‑testing with 32 Portuguese patients and final adjustments based on feedback from participants. Results: The final Portuguese versions of the iHOT‑12 and iHOT‑33 demonstrated excellent internal consistency (Cronbach’s alpha of 0.90 and 0.96, respectively) and test‑retest reliability (ICC of 0.88 and 0.90). The questionnaires were well accepted, with culturally adapted items. Conclusion: The Portuguese versions of the iHOT‑12 and iHOT‑33 are valid and reliable tools for assessing the quality of life of Portuguese patients with hip pathologies, contributing to improvements in the assessment and treatment of these patients.
