Abstract

The validity of a link between gun violence and mental illness has been the subject of ongoing research and policy debates. This study compares the burden of mental illness among adults incarcerated for violent versus property offenses as well as for firearm versus non-firearm violence, including lethal and non-lethal acts. The study utilizes the 2016 Survey of Prison Inmates (SPI) data. Results show that respondents convicted of violent crimes are more likely to have been diagnosed with mental illnesses than those convicted of property crime. However, differences in mental illness burden among individuals convicted of firearm and non-firearm violence are not statistically significant. Also, mental illness burden did not distinguish victim counts in incidents of firearm shootings, providing no evidence of a relationship to mass shooting risk. Overall, mental illness has an unique association with engaging in violent crime but not committing gun violence nor multiple victim shootings.
