Comparison of the Two Validated German Versions of the "Tinnitus Functional Index" for Switzerland and for Germany

Tinnitus is defined as a perception of sound without any external sound source. Chronic tinnitus is a frequent condition that can affect the quality of life. The questionnaire "Tinnitus Functional Index (TFI)" promises to be the new gold standard in tinnitus evaluation. Due to the forward and backward translation of this questionnaire, there are two different German versions of TFI for Switzerland and Germany. Both German versions were validated. The aim of this study is to compare the two German versions of the TFI with each other and to recommend the better one for the further use in tinnitus evaluation for the German speaking population.
