Input: Eight trials comprising 468 participants were included. For the primary outcome of subjective tinnitus loudness we found no evidence of a difference between CBT and no treatment or another intervention (yoga, education and 'minimal contact - education'). In the secondary outcomes we found evidence that quality of life scores were improved in participants who had tinnitus when comparing CBT to no treatment or another intervention (education and 'minimal contact education'). We also found evidence that depression scores improved when comparing CBT to no treatment. We found no evidence of benefit in depression scores when comparing CBT to other treatments (yoga, education and 'minimal contact - education'). There were no adverse/side effects reported in any trial. In six studies we found no evidence of a significant difference in the subjective loudness of tinnitus. However, we found a significant improvement in depression score (in six studies) and quality of life (decrease of global tinnitus severity) in another five studies, suggesting that CBT has a positive effect on the management of tinnitus.
Output:

Eight trials (468 participants) are included in this review. Data analysis did not demonstrate any significant effect in the subjective loudness of tinnitus. We found, however, a significant improvement in the depression associated with tinnitus and quality of life (decrease of global tinnitus severity), suggesting that cognitive behavioural therapy has a positive effect on the way in which people cope with tinnitus. Further research should use a limited number of validated questionnaires in a more consistent way and with a longer follow up to assess the long-term effect of cognitive behavioural therapy in patients with tinnitus.
