title: Aggressive behaviour in schizophrenia: the role of psychopathology.
abstract: OBJECTIVE
  The aim of this study was to determine the psychopathological correlates of aggressive behaviour in schizophrenia.
  
  
  METHODS
  Thirty-one aggressive patients in rehabilitation wards meeting DSM-III-R criteria for schizophrenia were compared with 31 matched non-aggressive patients in relation to their psychopathology using the Clinical Global Index (CGI), Positive and Negative Symptoms scale (PANSS) and the Montgomery-Asberg Depression Rating Scale.
  
  
  RESULTS
  The aggressive group had significantly higher CGI, positive symptom, negative symptom, general psychopathology and total PANSS scores than the non-aggressive group. The two groups could be distinguished by three sets of symptoms: symptoms with verbal or/and physical aggression as part of their definition; symptoms suggesting frontal lobe impairment; and excitement. The two groups did not differ in their level of depressive symptomatology.
  
  
  CONCLUSIONS
  The aggressive group were overall more ill than the non-aggressive group, and the former could be distinguished from the latter by certain aspects of their psychopathology.
