Add another to the bucket of, "No, while mental health access is a problem it's not the cause of mass school shootings." and to the bucket of, "Yes, the research and data consistently points to access to firearms and American firearm culture as more significant causes of mass school shootings".A research team at Columbia University Irving Medical Center and the New York State Psychiatric Institute (NYSPI) examining 82 mass murders that occurred at least partially in academic settings throughout the world, found that most mass murderers and mass shooters did not have severe mental illness.
The study, led by Ragy R. Girgis, MD, and Gary Brucato, PhD, associate research scientist, also found that most mass murderers used firearms, and semi- or fully-automatic firearms most commonly. Among incidents of mass school murder not involving firearms, stabbing was the most common method.
The research(link is external and opens in a new window), published online Oct. 27 in the Journal of Forensic Sciences, according to study authors, is largest analysis ever conducted on mass school shootings.
“Our findings suggest that mass school shootings are different from other forms of mass murder, and that they should be looked at as a distinct phenomenon,” said Dr. Girgis, director of the Center of Prevention and Evaluation (COPE), a research clinic at Columbia/NYSPI specializing in the study and treatment of young adults at high risk for schizophrenia and other psychoses. “To prevent future mass school shootings, we need to begin to focus on the cultural and social drivers of these types of events, such as the romanticization of guns and gun violence, rather than on individual predictors.”
For the mass school shooting study, the researchers isolated cases of mass murder perpetrated at least in part at schools, colleges, and universities and categorized them by location (within or outside of the US), and whether firearms were used.
Of the 82 incidents of mass murder involving academic settings:
Nearly half (47.6%) and most involving firearms (63.2%) were U.S.-based
Consistent with previous reports, perpetrators of mass shootings involving academic settings are primarily Caucasian (66.7%) and male (100%)
Severe mental illness (e.g., psychosis) was absent in the majority of perpetrators; when present, psychotic symptoms are more associated with mass murders in academic settings involving means other than firearms
About half (45.6%) of mass school shootings ended with the perpetrator's suicide
Coauthor Paul S. Appelbaum, MD, the Elizabeth K. Dollard Professor of Psychiatry, Medicine and Law at Columbia, said that identifying mental illness as a primary cause of violence is misleading.
“The findings strongly suggest that focusing on mental illness, particularly psychotic illness, when talking about mass school shootings risks is missing other factors that contribute to the vast majority of cases, as well as exacerbating the already widespread stigma surrounding severe mental illness,” said Dr. Appelbaum.
