Obsessive compulsive disorder and depression--first results of a prospective study on 74 patients

1. Seventy-four patients who met DSM-III-R criteria for Obsessive Compulsive Disorder received a serotonin reuptake inhibitor and cognitive behavior therapy for 6 months (baseline to follow-up I). 2. In order to maximize therapeutic effects, different kinds of treatment were applied between follow-up I and follow-up II (12 months). 3. Patients were followed-up twice with respect to long-term outcome of obsessive compulsive disorder and depression. Forty % of the sample showed marked improvement at follow-up. No specific variant of treatment could be identified to be significantly more effective. 4. Cross-sectional investigations showed significant correlations between extent of depressive and obsessive compulsive symptomatology (admission, follow-up I and II).
