Individuals with psychosis are often feared. In fact, they are themselves likely to be victims of violence; however, the main aim of this review is to provide an overview of the evidence on relations between psychosis and violence to others. The terms psychosis and violence were used in a literature search limited to the Cochrane Library and PubMed, a manual search of 8 journals, and a follow-up of additional references in the articles found. The overview draws on new empirical data and major reviews. Almost all sound epidemiologic data on psychosis and violence dates from 1990. There is consistency on a small but significant relation between schizophrenia and violent acts. Since then there has also been movement toward understanding the nature of associations and progress on strategies for managing individuals who have psychosis and are violent. Public fears about individuals with psychotic illnesses are largely unfounded, although there would be benefit in greater attention to the safety of those in their close social circle. The task for the next 10 years must be the development and application of knowledge to improve specific treatments—that is, interventions that go beyond holding and caring to bring about substantial change.

“…However, this comorbidity is particularly important as it has been demonstrated repeatedly that schizophrenia with comorbid substance misuse increases the risk of violence considerably compared with schizophrenia without comorbidity. [13][14][15][16] The risk from substance misuse is thought to be additive rather than causative. 17 The National Confidential Inquiry into suicide and homicide identifies this combination of mental illness and substance misuse as probably the greatest clinical problem facing general adult mental health services and recommends a coordinated approach to training, service planning and research to improve the ability of general services to address this problem.…”

Changes in diagnoses before admission to a specialist medium secure unit

Aims and methodThere is evidence that changing diagnoses may be an important factor preceding homicide, but there is little literature on diagnostic antecedents to admission to specialist secure units after violent behaviour. Our aim was to establish the frequency of a history of changing diagnoses in patients in a UK specialist unit, and to explore the characteristics of these patients.ResultsIn total, 38 of 42 study participants had prior contact with psychiatric services. Just over 40% (16 of the 38) had had their diagnosis changed three or more times. All those who had major changes in their diagnosis had received a diagnosis of a psychotic illness at some point prior to the secure unit admission, but then had it withdrawn, only to be restored after prolonged assessment in the secure unit. Personality disorder and substance misuse comorbidity was common in this group; however, non-psychotic diagnoses were seen as more important than psychotic diagnoses by general services.Clinical implicationsChanges in diagnosis between first presentation to psychiatric services and admission to a medium-security unit were more common than would be expected from reports in the general literature. They are a testimony to the difficulties experienced by service providers in delivering a consistent service. This needs to be studied further.
