The Efficacy of TBCT Compared to ERP in the Treatment of OCD Patients, by the Assessment of Magnetic Resonance.

This is a sample made up of ninety-six adult individuals of both sexes to be divided into three groups: the experimental group of thirty-two patients with OCD who will be undergone Trial-Based Cognitive Therapy; the gold standard, with thirty-two people with OCD subject Exposure and Response Prevention and the control group of thirty-two healthy individuals. Interviews and therapeutic intervention occur in private practices researchers or medical schools accredited by UESPI. Experimental group: Will be eligible adults of both sexes with educational level equal to or higher education complete primary, aged between 18 and 60 years with OCD diagnosis confirmed according to criteria DSM-IV (APA, 1994). It is going to be excluded patients who had previously undergone treatment behavioral psychotherapy or cognitive-behavioral approach.

OBJECTIVES Evaluate the effectiveness of Trial-Based Cognitive Therapy (TBCT) compared to Exposure and Response Prevention (ERP) in the treatment of OCD patients, by neuroimaging tests such as MRI. 1. Describe the neuroanatomical profile of the sample participants before and after the psychotherapeutic intervention by MRI; 2. Compare the profile neuroanatomical between the experimental group and the control group by MRI; 3. Identify possible neuroanatomical differences in the participating sample of pre and post-treatment, both among individuals and among psychotherapeutic intervention groups; 4. To investigate associations between the results of MRI scans and indexes the scales currently used to assess severity of OCD.
