Study Overview
Brief Summary
This study will evaluate the effects of a computerized training program coupled with cognitive behavioral therapy (CBT) for OCD.
Detailed Description
This study will evaluate the effectiveness of a computerized training program (called Personalized Computerized Inhibitory Training, or PCIT) coupled with cognitive behavioral therapies (CBT) consisting of Exposures and Response Prevention in treating obsessive compulsive disorder (OCD) in patients who previously underwent CBT, but still have residual symptoms.

Outcomes
Primary Outcomes
Obsessive-compulsive symptoms measured after 3 weeks of treatment
Time Frame: 3 weeks
Measured by Yale-Brown Obsessive Compulsive Scale (YBOCS), considered the gold standard assessment tool. Y-BOCS comprises a Symptom Checklist and Severity Scale to consecutively rate obsessions and compulsions. The Checklist includes 54 common obsessions and compulsive behaviors, which are grouped according to thematic content. Symptoms that are endorsed over the past week are then globally rated by the clinician using a five-point scale ranging from 0 (none) to 4 (extreme) across five dimensions: (1) time/frequency, (2) interference, (3) distress, (4) resistance, and (5) degree of control. Obsessive and compulsive symptom severity are rated separately (scores range from 0 to 25) with these scores summed to create a total OCD severity score (range, 0-50). Symptom severity scores: mild symptoms (0-13), moderate symptoms (14-25), moderate-severe symptoms (26-34), and severe symptoms (35-40).26
