title: Schizophrenia and serious violence: a clinical-profile analysis incorporating impulsivity and substance-use disorders.
abstract: OBJECTIVE
  This study is an exploration of the role of SUD and impulsivity in individuals with schizophrenia who are at higher risk of serious violence (SV).
  
  
  METHODS
  Multiple correspondence analysis (MCA) and cluster analysis (CA) were performed on a sample of 139 males meeting DSM-IV diagnostic criteria for schizophrenia-spectrum disorders (SSD).
  
  
  RESULTS
  Impulsivity was the main dimension differentiating individuals. SUD and SV were strongly linked. CA yielded four clusters; one related to serious violence, SUD and a higher incarceration rate.
  
  
  CONCLUSIONS
  Subgroups of SSD at risk of SV were found. SUD appear to be a major risk factor for SV and incarceration.
