Clinician-Supported Internet-Delivered Psychological Treatment of Tinnitus.
Internet-delivered psychological treatments for tinnitus distress have existed for more than 15 years, and there are a slowly growing number of studies. The aim of this brief report is to review the evidence and to comment on the future potentials of Internet treatments for tinnitus. Studies were retrieved, and in total 6 controlled studies were included in the review with 9 different comparisons (6 in which the treatment was compared against a control group and 3 in which Internet treatment was compared against group treatment). Moreover, 2 open studies based on clinical samples in regular care were also included in the review. The outcomes for the 2 controlled sets of studies were analyzed using meta-analytic methods. For the 6 studies comparing Internet treatment against a no-treatment control condition, a moderate effect size was found (Hedges's g = 0.58). The 3 studies comparing Internet treatment against face-to-face group treatments showed a small difference of Hedges's g =0.13. Internet-delivered psychological treatment holds promise as a treatment alternative to other standard forms of treatment delivery, including group treatment. Larger studies are needed as well as ways to blend information technology with regular services.
