Lead Sponsor
University of Sao Paulo General Hospital
Brief Summary

The aim of this study is to assess the implementation of Internet-based Cognitive Behavioral Therapy (I-CBT) treatment in a Brazilian sample.

Researchers will compare 140 participants (70 with I-CBT and 70 in usual care to see if the treatment is feasible.

Participants will undergo online treatment for OCD, lasting 10 to 14 weeks.

Detailed Description

Obsessive-compulsive disorder (OCD) affects 2 to 3% of the adult population worldwide. The efficacy of pharmacological therapy with IRS and cognitive-behavioral therapy (CBT) is well recognized, but the clinical spectrum of OCD symptoms makes it difficult for patients to engage in sessions outside the home, decreasing treatment adherence. CBT is a psychological intervention increasingly delivered over the internet, with studies showing its efficacy in patients with OCD. The present study aims to verify the efficacy of implementing internet-based psychotherapy (I-CBT) in the context of a developing country, identifying the barriers and facilitators of this implementation. It will be a pragmatic, randomized-controlled, parallel, open-label, two-arm clinical trial. The implementation will be carried out in the cities of Indaiatuba and Jaguariúna, state of São Paulo, in all their Basic Health Units, in which 140 participants will be randomized between the I-CBT and usual treatment (UT) groups. Results will be assessed post-treatment and at 3- and 12-month follow-up. The hypothesis is that I-CBT is an effective and feasible treatment modality for OCD in a large Brazilian sample.
