Diagnostic and treatment of obsessive compulsive disorder

A.J.L.M. van Balkom, P. van Oppen

In this review diagnosis, epidemiology, etiology, assessment and treatments of obsessive compulsive disorder (OCD) are discussed. OCD is diagnosed on the basis of a psychiatric interview. OCD can be reliably diagnosed with ADIS, a structured interview for anxiety disorders. The life-time prevalence rate of this chronic disorder is 2.4%. Research on etiological factors has yielded conflicting findings, but treatment of OCD can be successful with serotonergic antidepressants, behavior and cognitive therapy. The treatment effect of cognitive-behavioral therapy is larger than of antidepressants. The combination of antidepressants with behavior therapy treatment does not enlarge the efficacy of behavior therapy alone.
