Risk Factors Help Predict Violence in Adults with Mental Illness
New research suggest three factors increase the risk of violent behavior among people with mental illness. Investigators discovered alcohol use, engagement in violent behavior, or being the victim of violent behavior predict future violence.
The findings will help mental health professionals and others working with adults with mental illness to identify potential warning signs. Early identification of risk factors will allow professionals to intervene and hopefully prevent violent behavior.
“Our earlier work found that adults with mental illness are more likely to be victims of violence than perpetrators — and that is especially relevant to this new study,” said Dr. Sarah Desmarais, an associate professor of psychology at North Carolina State University and co-author of a paper.
“One of the new findings is that people with mental illness who have been victims of violence in the past six months are more likely to engage in future violent behavior themselves.”
For the study, researchers compiled a database of 4,480 adults with mental illnesses, including schizophrenia, bipolar disorder, and depression. Subjects in the database were those who had answered questions about both committing violence and being victims of violence in the previous six months.
The database drew from five earlier studies that focused on issues ranging from antipsychotic medications to treatment approaches. Those studies had different research goals, but all asked identical questions related to violence and victimization.
Investigators reviewed the data to determine which behaviors, events, and characteristics were most predictive of violent behavior over a six-month period. Violent behavior, in this context, ranged from pushing and shoving to sexual assault and assault with a deadly weapon.
The researchers found three risk factors that were predictive of violent behavior: if an individual is currently using alcohol; if an individual has engaged in violent behavior over the past six months; and if an individual has been a victim of violence within the past six months.
“We found that these risk factors were predictive even when we accounted for age, sex, race, mental illness diagnosis and other clinical characteristics,” Desmarais said.
In contrast, the researchers found that current drug use was not predictive of violent behavior, when age, sex, race, mental illness diagnosis, and other clinical characteristics were considered.
“This is useful information for anyone working in a clinical setting,” Desmarais said.
“But it also highlights the importance of creating policies that can help protect people with mental illness from being victimized. It’s not only the right thing to do, but it makes for safer communities.”
