Key indicators linking violence and mental illness identified

New York : US researchers claim to have found the risk factors associated with adults having mental illness becoming victims or perpetrators of violence.

Previous study found that almost one-third of adults with mental illness were likely to be victims of violence within a six-month period.

"We found that all of these indicators mattered, but often in different ways," said Sarah Desmarais, Associate Professor at North Carolina State University in the US.

"For example, drug use was a leading indicator of committing violence, while alcohol use was a leading indicator of being a victim of violence," Desmarais added.

However, the researchers also found that affective symptoms category of psychological symptoms were also closely associated with violence.

"By affect, we mean symptoms including anxiety, depressive symptoms and poor impulse control. The more pronounced affective symptoms were, the more likely someone was to both commit violence and be a victim of violence," Desmarais noted.

The study highlights the importance of interventions to treat mental-health problems in order to reduce community violence and instances of mental-health crises.

"By treating people who are exhibiting these symptoms, we could reduce violence. Just treating drug or alcohol use which is what happens in many cases isn't enough. We need to treat the underlying mental illness that is associated with these affective symptoms," Desmarais said, in the paper appearing in the journal Psychological Medicine.
