The Tinnitus Annoyance Questionnaire included 13 questions to measure the annoyance experienced by patients because of tinnitus. Patients responded using a visual analog scale ranging from 0 (never) to 100 (always).64
Results presented in figures. Numeric data unavailable.
The Tinnitus Questionnaire consists of 52 items that incorporate six subscales: emotional distress, cognitive distress, intrusiveness, auditory perceptual difficulties, sleep disturbance, and somatic complaints. The maximum score is 84. The higher the total score, the more distress caused by tinnitus.72
The Tinnitus Handicap Inventory consists of 25 items on the impact of tinnitus on daily life. The maximum score of 100 is divided into five grades that represent the severity of tinnitus: slight, mild, moderate, severe, and catastrophic.73
The visual analog scale measures the loudness of tinnitus; patients marked the strength of tinnitus on a scale of 0 (no tinnitus) to 10 (very loud, disturbing tinnitus).74
