Summary
This study examined how useful it is to teach veterans coping skills for dealing with tinnitus, also called ringing in the ears. A psychological intervention, cognitive-behavioral therapy, was used to teach coping skills even though tinnitus is not a psychological disorder. Participants in Period 1 of the study were assigned to one of two groups for the duration of the study and were blinded to their group assignment until the end of the study. One group received education about tinnitus. The other group received education about tinnitus plus additional ways to cope with problems associated with tinnitus such as sleep disturbance and frustration. Participants were selected to participate if their tinnitus was severe and they had been exposed to loud sound. Participants attended up to six weekly group meetings. It was predicted that participants who were randomly assigned to the cognitive behavioral therapy group would report a greater reduction in tinnitus severity than education controls. During Period 2 of the study, a third "standard care" arm was added. Baseline and outcome data of the 4 participants who completed the study after this third arm was added to the study design are not reported.
Eligibility Criteria
Inclusion Criteria

- Subjects were interested in participating in the study and had moderate to severe, chronic (>6 months) tinnitus.
- Following a brief assessment of tinnitus severity by the project coordinator, the research otologist and research audiologist conducted tinnitus and audiological evaluations to determine subject eligibility.
