Exposure with response prevention and serotonergic antidepressants in the treatment of obsessive compulsive disorder: a review and implications for interdisciplinary treatment

Abstract

A comprehensive review of controlled investigations examining the effectiveness of exposure with response prevention (ERP) and clomipramine (CMI), as well as other serotonergic anti-depressants, in the treatment of Obsessive Compulsive Disorder (OCD) was conducted. Overall, findings suggested that ERP is more effective than CMI, particularly in alleviating rituals, but CMI may be more effective in reducing obsessive compulsive behavior among individuals with concomitant severe depression, obsessions only, and overvalued ideation. In addition, the literature favors ERP in terms of side-effects and risks, dropout, and maintenance, while one advantage of drug therapy is that less time and effort are required by the therapist and patient. Directions for interdisciplinary treatment are discussed.
