Forensic psychiatric inpatients and aggression: an exploration of incidence, prevalence, severity, and interventions by gender.

BACKGROUND

Previous investigations suggest that women judged to be not criminally responsible on account of mental disorder (NCR-MD) differ markedly from their male counterparts in important ways, underscoring the necessity of subsequent study.

OBJECTIVE

The goal of the present study was to inform our understanding of the presenting profile of female forensic psychiatric patients and contrast their risk of inpatient aggression with their male counterparts.

METHOD

The population of patients assessed and/or treated at a secure Canadian forensic psychiatric hospital were available for study. In total, 527 patients had complete data and were part of intensive retrospective file reviews; inpatient aggression was evaluated using the Overt Aggression Scale.

RESULTS

Women were no less likely than men to have a violent index offence and to perpetrate inpatient aggression. Examining the range of aggressive behaviours and severity levels did little to increase the relevance of gender to inpatient risk.

DISCUSSION

Female forensic patients represent a highly selected subgroup of women with exceptional clinical and behavioural challenges and associated treatment needs.
