Primary News: Violence in Schizophrenia: Other Risk Factors Matter More Than the Disease

The recent study by Fazel et al. (2009) is based on a sample comprising what amounts to be the entire population of schizophrenia patients in Sweden. This is a major strength of the study. The principal outcome of interest was conviction for violent crime. The authors reported odds ratios for violent crime in patients with and without substance abuse comorbidity, compared to a control group.

Schizophrenia patients commit acts of violence in the community and in the hospital. In the United States, arrests of psychiatric inpatients for assaults and other aggressive behaviors that they commit are rare, and prosecution leading to conviction is extremely unlikely. I suspect that the situation in Sweden is not dramatically different in this respect. If this is so, I have some comments.

First, schizophrenia patients generally spend more time in hospitals than members of the general population do. A minimum of two hospitalizations was an eligibility criterion for inclusion in the group of schizophrenia patients in this study. During hospitalization, they were not available to...  Read more

Comment by Seena Fazel, Martin Grann, and Niklas Långström
We are grateful for the interest and comments that our paper has attracted. We would like to take this opportunity to respond to some of these comments.

First, Dr. Volavka raises the potentially important issue of time at risk and whether the patients had less time at risk than the controls. In Sweden, any serious offences by hospital inpatients are reported to the police and lead to convictions. This is partly a consequence of the insurance system, which requires police involvement if insurance claims are made by health care workers or other patients. It is possible that minor offending, such as theft, by hospital patients does not lead to conviction, but our study focused on violent offending.

Second, we agree with Dr. Torrey that our comments about treatment for substance abuse comorbidity in patients should not detract from the need for treatment of the underlying schizophrenia. A recent review reinforces Dr. Torrey’s point and suggests that consideration should be given to using...  Read more
