Comprehensive firearm background checks

Evidence Rating

Some Evidence

Health Factors

Decision Makers

Federal law requires licensed firearm dealers to conduct background checks of potential handgun purchasers’ criminal histories via the National Instant Criminal Background Check System (NICS) which includes fugitive status, court restraining orders, and some information regarding severe mental illness. States can require collection and review of a broader set of disqualifying criteria (e.g., in-state criminal records of misdemeanor convictions, domestic violence restraining orders, juvenile court records, and histories of substance abuse or mental health issues), expanding prohibitions on purchase. Comprehensive checks can be adopted with other efforts to strengthen background checks such as universal background checks and regulations that require licenses to purchase or own firearms (LCPGV).

Expected Beneficial Outcomes (Rated)

  • Reduced homicide

  • Reduced suicide

  • Reduced intimate partner violence

Evidence of Effectiveness

There is some evidence that comprehensive background checks reduce firearm homicide and suicide, as well as intimate partner homicides (, ). Additional evidence is needed to confirm effects ().

Comprehensive background check laws can decrease homicide and suicide rates more than the narrower requirements of the federal background check (). Prohibiting firearm possession by those with domestic violence restraining orders via comprehensive checks can reduce intimate partner violence rates (). Comprehensive background checks may protect against fatal violence by keeping firearms from high-risk individuals (); adding checks for mental health concerns may reduce firearm suicide rates more than checks of criminal history alone ().

Impact on Disparities

No impact on disparities likely

Implementation Examples

As of October 2015, seven states (California, Illinois, Massachusetts, Minnesota, Oregon, Pennsylvania, and Washington) require comprehensive checks, searching in-state mental health records of prospective purchasers during the background check process. Three states (Pennsylvania, Utah, and Wisconsin) prohibit firearm sales for individuals with juvenile court records and two states (Massachusetts and Wisconsin) prohibit firearm sales for individuals with domestic violence protective orders against them (LCPGV).

Most states prevent local governments from enacting gun laws via state preemption legislation (Grassroots Change); as of 2015, only seven states (California, Connecticut, Hawaii, Illinois, Massachusetts, New Jersey, and New York) allow local governments to enact gun laws.
