Current understanding of violence and aggression: assessment and treatment.

Links between violence, aggression, and mental illness are well documented. Despite this association, our current understanding of the causation and optimal treatment of aggression remains limited. This lack of knowledge is alarming because nurses treating patients with mentally illness are frequent targets of patient aggression. Consequently, the aim of this article is to provide contemporary information regarding the concept of patient aggression, assessment of violent behavior, and implementation of treatment interventions. A review of pharmacological and psychosocial strategies are presented as well. These findings provide psychiatric nurses with a conceptual model as well as practical interventions for patient aggression.
