Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this multi-site randomized clinical study was to assess treatment outcomes for three forms of tinnitus treatment: Tinnitus Retraining Therapy (TRT), Tinnitus Masking, and Tinnitus Education (TED). There were four study sites: VAMC Audiology Clinics at Bay Pines, FL; Portland, OR; Seattle, WA; and San Diego, CA. Thirty-six subjects (Veterans) were enrolled into treatment at each site - 12 into each treatment group. Each subject received 18 months of treatment. Treatment appointments and outcome questionnaires occurred at 0, 3, 6, 12, and 18 months. Qualified subjects were initially randomized to one of the treatment groups or to a 6-month Waiting List group. Those in the Waiting List group completed outcome questionnaires at 3 and 6 months, and were randomized into one of the three treatment groups. They then received 18 months of treatment as above.
