The aim of this prospective follow-up study of obsessive compulsive disorder (OCD) with onset in childhood and adolescence is to describe the long-term outcome of social adjustment. Methods: 48 of 58 former patients treated for OCD in the Clinic for Child and Adolescent Psychiatry of the University of Würzburg were assessed by standardised measures after a follow-up period of 5.8 years. Results: At follow-up, 45.8% of the participants fulfilled the criteria for OCD according to DSM-IV. The level of psychosocial functioning was closely connected to the severity of OCD, however impairment regarding social-communicative skills as well as partnership was found in the sample as a whole. Discussion: A great focus in therapy of OCD patients should be laid on the mediation of social skills. Time latency between onset of OCD and consultancy seems relevant not only in the course of symptom development but also for the level of psychosocial adjustment.
