Abstract
Introduction: The psycho-emotional assessment is of utmost importance for evaluation of patients with tinnitus. The Tinnitus Handicap Inventory (THI), is the most known and validated test for this purpose. Objectives: We propose a linguistic validation of the THI, in order to obtain reliable answers in our country. Materials and Methods: We performed a translation of the original English questionnaire and assessed its feasibility by applying it in a group of patients with tinnitus. Statistical analysis included internal validity (Cronbach’s alpha) and linear correlation tests (Pearson coefficient). Results: We evaluated 60 patients with a mean age of 59 years. We obtained a Cronbach’s alpha index of 0.97 for the whole questionnaire. Conclusions: The adapted version of the THI shows satisfactory levels of internal consistency for the assessment of disability caused by tinnitus.
