title: The relationship of antisocial personality disorder and history of conduct disorder with crime incidence in schizophrenia.
abstract: BACKGROUND
  Commission of crime and hostility and their forensic consequences in a patient with schizophrenia can worsen the patient's condition and disturb his family, society, and even the psychiatrist. Based on previous research, patients with schizophrenia are at a higher risk for crime. It is not clear whether this is due to the nature of schizophrenia, comorbidity of antisocial personality disorder, or the history of conduct disorder in childhood. In this study, we investigated this hypothesis.
  
  
  METHODS
  In this case-control study, 30 criminal and 30 non-criminal patients with schizophrenia, who had been referred by the court to the Forensic Medicine Center of Isfahan, were evaluated for antisocial personality disorder, history of conduct disorder, and psychopathy checklist-revise (PCL-R) score.
  
  
  RESULTS
  Frequency distribution of antisocial personality disorder (73.3%), history of conduct disorder in childhood (86.7%), and score of PCL-R ≥25 (indicating high probability of hostility) in patients (40%) were significantly higher in criminal patients than in non-criminals (10%, 30% and 0%, respectively; P < 0.001).
  
  
  CONCLUSIONS
  More prevalence of antisocial personality disorder, history of conduct disorder, and high score of PCL-R (≥25) in criminal schizophrenic patients may indicate that in order to control the hostility and for prevention of crime, besides treating acute symptoms of psychosis, patients might receive treatment and rehabilitation for comorbidities too.
