Czech version of the Tinnitus Handicap Inventory

Introduction: The Tinnitus Handicap Inventory (THI) is a key tool for assessing the impact of tinnitus on a patient‘s life, emotional state and sleep quality, allowing for treatment planning and monitoring. It is also used by researchers to collect data, contributing to a better understanding of this complex dia gnosis. Methodology: The linguist then compiled these versions into a fi nal version, which was edited for best comprehensibility while preserving the original meaning of the questions. This Czech version was then translated back into English by a second linguist to check its factual consistency with the original. Result: It was confi rmed by both linguists and experts that both the translation and the back-translation were meaningfully consistent with the original. Conclusion: The translation of the THI has been methodologically rigorous, is ready for validation and promises to make a signifi cant contribution to tinnitus dia gnosis and research in the Czech Republic, and an electronic version of the questionnaire could be easily made available for wider use.
