Conditions studied: Violence
In brief
This study evaluates exposure to California's Armed and Prohibited Persons System (APPS) and risk of future violence and other important outcome events among individuals who legally purchased firearms in the past but have since become prohibited from owning them. The main hypothesis is that APPS will be associated with a significant reduction in risk for future violence among individuals who are directly affected.
