There are innumerable questionnaires for tinnitus, and the THI is a popular one. The THI is also called the "THQ" for tinnitus handicap questionnaire.
A PDF version of the THI is here.Online version
The tinnitus handicap inventory was developed by the same authors who developed the dizziness handicap inventory, "To develop a self-report tinnitus handicap measure that is brief, easy to administer and interpret, broad in scope, and psychometrically robust." (Newman et al, 1996)
The THI is not a diagnostic test -- rather it produces scores related to the percieved tinnitus handicap -- a subjective quantity.
The THI is a 25 item test, and the maximum score is 100.
Salviati et al (2013) reported that scores above 36 suggest psychiatric distress.
We also have a large repertoire of dizzy patients in our clinic practice with tinnitus, where we have obtained the THI. For these, the distribution is much different than for the DHI . This data is from the beginning of 2018(n=854). These are mainly people who are dizzy, and whose chief complaint is not tinnitus at all. There may be a few who are mainly being seen for tinnitus however.
