Background Research has repeatedly demonstrated that schizophrenia has a small but significant association with violence. It is further recognised that a subgroup of people with such links also have personality disorders, but the extent to which type of violence or aggression varies according to subgroup is less clear. Aim This study aimed to investigate, among co‐morbid cases, if the number or type of personality disorders predicts type of aggression. Methods In a cross‐sectional study, 108 patients with schizophrenia were assessed for personality disorder, Axis‐I diagnosis, verbal IQ, social functioning and type of aggression. Results Logistic regression revealed that the more personality disorders identified (Cluster B personality disorders compared with Clusters A and C) and anti‐social personality disorder compared with other Cluster B disorders significantly predicted premeditated aggression. Conclusions These findings suggest that detailed personality assessment should be a routine part of comprehensive assessment of patients with schizophrenia. Improved knowledge of the presence and type of personality disorders may help detect and manage the risk of some types of aggression. Copyright © 2013 John Wiley & Sons, Ltd.
