title: [Psychotic disorders and drug abuse in adolescents].
abstract: OBJECTIVE
  The relation between substance abuse and symptoms of psychosis as well as related disorders was evaluated among patients at the Hospital for Child and Adolescent Psychiatry and Psychotherapy of the University of Marburg.
  
  
  METHODS
  Using a child and adolescent version of the IRAOS (Instrument of the Retrospective Assessment of the Onset of Schizophrenia, Häfner et al., 1990), all patients with a co-morbid substance abuse were assessed. Patients with a drug-induced psychosis (n = 8) were compared to psychotic patients with co-morbid substance abuse and to patients with other psychiatric disorders and substance abuse (n = 30).
  
  
  RESULTS
  These three groups could be significantly distinguished on the basis of pre-morbid symptoms and pre-morbid functioning.
  
  
  CONCLUSIONS
  The IRAOS shows some evidence that psychotic patients with co-morbid substance abuse can be distinguished from patients with a drug-induced psychosis according to the course of the initial psychopathology and pre-morbid functioning.
