Validation of a Korean Version of the Tinnitus Handicap Questionnaire

The goal of the present study was to evaluate the reliability and validity of the Korean version of the tinnitus handicap questionnaire (THQ-K). A total of 60 patients were included in this study. Patients responded to the THQ-K, the tinnitus handicap inventory (THI), Beck's depression index (BDI), and the visual analogue scale (VAS) for loudness and pitch, loudness match, and minimum masking level (MML) test were performed. Internal consistency of the THQ-K was examined using Cronbach coefficient alpha. Cronbach alpha was 0.96. The THQ-K showed a significant correlation with THI, BDI, VAS for distress, and VAS for loudness, but no significant correlation with psychoacoustic measurement of tinnitus, such as loudness match, pitch match, and MML. The THQ-K is a reliable and valid test for evaluating the degree of handicap due to tinnitus for both research and clinical use.
