TQ, tinnitus questionnaire (German version); THI (tinnitus handicap inventory); TFI, tinnitus functional index. ICC, intraclass correlation (0.50–0.75, moderate, 0.76–0.90, good agreement); CI, confidence interval. Bold ICC coefficients indicate moderate agreement (upper level confidence interval >0.50); all other indices show “poor” agreement.
