Study Summary
The primary purpose of the Tinnitus Retraining Therapy Trial (TRTT) is to assess the efficacy of tinnitus retraining therapy (TRT) as a treatment for severe debilitating tinnitus. TRT is a non-medical intervention that uses directive counseling (DC) and sound therapy (ST)to habituate the patient's associated negative emotional reactions to tinnitus, its perception, and ultimately, its impact on the patient's life.
Primary Outcome
The TQ is a tinnitus-specific health-related quality of life instrument with 52 statements that the respondent marks as true, partly true, or not true. The TQ is scored from 0 to 102, with higher scores indicating more of an impact of the tinnitus on quality of life. Subscales include emotional distress, intrusiveness, auditory perceptual difficulties, sleep disturbance,and somatic complaints.
Interventions
- BEHAVIORAL Standard of Care (SC)
- DEVICE Conventional sound generator (SG)
- DEVICE Placebo sound generator (placebo SG)
- BEHAVIORAL Directive Counseling (DC)
