Background:
Tinnitus presents a major public health challenge, impacting quality of life. With conventional therapies being often time-consuming and costly, interest in Internet-based treatments, such as auditory treatments and Internet-based cognitive behavioral therapy, has grown due to their improved patient adherence. This meta-analysis aims to review existing scientific literature to assess the effectiveness of Internet-based therapies (IBTs) in treating tinnitus.
Methods:
Studies up to February 2024 using the Tinnitus Functional Index (TFI), Tinnitus Handicap Inventory (THI), or Tinnitus Reactions Questionnaire (TRQ) to monitor tinnitus before and after IBTs were searched in PubMed, Google Scholar, Web of Science, and the Cochrane Central Register of Controlled Trials. Variation of the score with time was analyzed and a comparison was made with non-IBT studies. Treatment effects were analyzed using Cohen's d model.
Results:
A total of 14 articles were considered, with a total of 1574 patients. Significant improvements in questionnaire scores were noted post-treatment. In the IBT group, THI and TFI decreased by 17.97 and 24.56 points, respectively (Cohen's d THI: 0.85; TFI: 0.80). In the control group, THI and TFI decreased by 13.7 and 4.25 points, respectively (Cohen's d THI: 0.55; TFI: 0.10).
Conclusions:
Internet-based therapies showed reliable effectiveness, possibly due to improved patient compliance, accessibility, cost-effectiveness, and customization.
