OBSESSIVE COMPULSIVE DISORDER (OCD)
Conditions
Brief summary
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.
Detailed description
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.
Interventions
BEHAVIORALCognitive Therapy
Trial-Based Cognitive Therapy (TBCT) is a three-level, three-phase, case formulation approach. TBCT's foundation is in cognitive therapy (CT); however, it has a unique approach to conceptualization and techniques that make it a distinct intervention in modifying patients' core beliefs, especially those about the self. All the individuals will be submitted to MRI.
BEHAVIORALBehavioral Therapy
The Behavioral therapy employs the technique of Exposure and Response Prevention ( ERP ).The technique involves directly exposing patients to recall stimulation of obsessive thoughts and prevent them from performing the compulsive rituals. All the individuals will be submitted to MRI.
