Outline of Final Research Achievements

In this study, we examined the neural basis of meta-cognition in OCD patients. Next, we developed the new program of meta-cognitive intervention in behavior therapy-resistant OCD patients. .Twenty OCD patients participated in an open study testing the effectiveness of the meta-cognitive intervention. Patients with a reduction in their global Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score of 35% or greater were judged as being responsive to the treatment. Among 12 OCD patients, five OCD patients were defined as responders of the treatment. In addition, five OCD patients improved on scores of questionnaires of meta-cognition. Compared with responders (n=5), non-responders exhibited significantly worse of executive function at the time of baseline, and over-estimated the wasted time during the rituals. The new program of meta-cognitive intervention is likely to be beneficial to t behavior therapy-resistant OCD patients.
