Abstract

Objectives: This study is an exploration of the role of substance use disorder (SUD) and impulsivity in individuals with schizophrenia who are at higher risk of serious violence (SV). Methods: Multiple correspondence analysis 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 4 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.
