Public Awareness of and Personal Willingness to Use California's Extreme Risk Protection Order Law to Prevent Firearm-Related Harm.

Importance: Extreme risk protection order (ERPO) laws temporarily suspend firearm and ammunition access by individuals whom a judge has deemed to be at substantial risk of harming themselves or others. Despite widespread recent adoption of these laws, use of ERPOs has been limited. Barriers to ERPO uptake remain unclear. Objective: To assess public awareness and perceived appropriateness of and willingness to use ERPOs in various risk scenarios, and to identify reasons for being unwilling, overall and by firearm ownership status, to inform efforts to improve ERPO implementation. Design Setting and Participants: This was a cross-sectional study using data from the 2020 California Safety and Wellbeing Survey, a statewide internet survey on firearm ownership and exposure to violence and its consequences, conducted from July 14 to July 27, 2020. Adult respondents were recruited from the Ipsos KnowledgePanel using probability-based sampling methods. Responses were weighted to be representative of the adult population of California. Main Outcomes and Measures: Awareness and perceived appropriateness of gun violence restraining orders (GVROs; California's official term for ERPOs), willingness to use a GVRO for a family member at risk of harm, and reasons for being not at all willing to use a GVRO in 1 or more risk scenarios, overall and by firearm ownership status. Results: Of the 5018 panel members invited, 2870 (57%) completed the survey. Of these respondents (mean [SD] age: 47.9 [16.9] years; 52.3% women; 41.9% White, 34.7% Latinx, 14.4% Asian, and 5.8% Black individuals), 65.6% (95% CI, 63.0%-68.1) had never heard of a GVRO or a red flag law. Firearm owners were significantly more likely (20.5%; 95% CI, 15.9%-26.0%) than nonowners who live with owners (6.1%; 95% CI, 3.7%-10.0%; Conclusions and Relevance: In this cross-sectional survey study, public awareness of GVROs was low, but perceived appropriateness of and willingness to use these tools at least some of the time was high. Foci for efforts to address barriers to GVRO use in California were identified; similar challenges likely exist in other jurisdictions.
