The epidemic of gun violence in the United States is a topic of growing concern, particularly within the fields of policy, health care, forensic psychology, and criminology. Public records indicate that the majority of all gun-related fatalities in America are firearm suicides, but there are considerable inconsistencies between data trends in different states. The American federal system of government allows for legislative discrepancies between state jurisdictions, which offers a possible explanation for these data variations. This study examined state-level regulations for gun ownership and sales as a factor of firearm suicide rates, predicting that states with more restrictive laws would have lower rates of self-inflicted gun violence. Laws included the presence of red flag laws, child access prevention/secure storage laws, and required background check/permit to purchase laws. The method used to evaluate the effects of these laws was a series of paired one-tailed T-tests that compared firearm suicide rates from 5 years before and 5 years after the legislation entered into force. Results from these tests demonstrated an association between reduced suicide rates and the presence of red flag laws and child access prevention/secure storage laws, which was in line with the predicted outcome. However, nonsignificant evidence was found for an association between a change in firearm suicide rates and required background check/permit to purchase laws, which was unexpected and may be due to small sample size. These results suggested that there may be evidence for the efficacy of red flag laws and especially child access prevention/secure storage laws, for which the correlation was strongest. This information can be used to advise policy agendas and maximize government resources. Further study including controls for certain economic and social variables is recommended to expand upon these conclusions.
