Reframing Firearm Injury Prevention Through Bystander Interventions for Youth Shooting Sports Participants

Firearm injury and mortality is a major public health concern for American youth age 1-19. Only motor vehicle crashes kill more American youth than firearms. In 2018 alone, 1729 American youth died from firearm injuries (50% firearm homicide, 42% firearm suicide) and over 6500 youth were treated in an emergency department for firearm injury; these injuries have major long-term consequences for youth and their families. Approximately one-third of American youth live in a home with a firearm. Risk factors for youth firearm injury and death, such as unsafe home storage of a firearm, prior victimization/aggression, substance use, and depressive symptoms, can be modified. Community partnerships are essential for developing and enacting effective change in injury risk factors, particularly for youth. Due to the fraught political landscape and lack of research funding, partnerships with firearm owners and firearm safety training programs to create and disseminate effective, non-policy-based preventive interventions for youth firearm injury are lacking.

Bystander intervention (BI) is an intervention framework rooted in social psychological theories such as the Theory of Planned Behavior (TPB), with proven efficacy and effectiveness targeting both individual and community behavior change. "Guardians 4 Health" is a three-part, already-piloted intervention that uses the BI framework and TPB mechanisms to promote community norms change about firearm safety, BI, and harm reduction techniques (e.g., safe storage, reducing access to lethal means, conflict resolution). Recognizing that BI is most rigorous when led by credible messengers, Guardians 4 Health uses instructional, peer-to-peer, and social-media strategies in conjunction with community organizations that are deeply connected to firearm safety efforts. Pilot data supports Guardian 4 Health's acceptability and feasibility in changing firearm owners' norms and behaviors.

The necessary next step in this intervention development is to evaluate its effectiveness using a randomized, controlled study design. Our community partner, the National 4-H Shooting Sports Program, is a national leader and trusted messenger for firearm safety. Across the United States, 20,000 trained adult Club Leaders, 5,000 Teen Ambassadors, and 450,000 youth Shooting Sports participants (age 8-18) learn marksmanship, and safe and responsible use of firearms, through its structured curriculum. Leaders from 4-H are excited to implement and study Guardian 4 Health among their Shooting Sports Clubs and communities to reduce youth firearm injury and mortality risk. Our research team will evaluate Guardian 4 Health's effectiveness, compared to usual 4-H training, in changing firearm injury prevention norms, attitudes, behavioral intention, and practice among a sample of one hundred 4-H Shooting Sports Club communities, via a Type I Hybrid randomized, controlled effectiveness trial. Aims are:

Refinement and Planning (Year 1): Adapt Guardians 4 Health for the 4-H Shooting Sports Club context Aim 1: Conduct a series of key informant interviews with an advisory panel of up to 40 key stakeholders (teen and adult 4-H Shooting Sports leaders representing a diverse group of communities and 4-H experience) to ensure The Reframe addresses 4-H-specific issues of acceptability, feasibility, and appropriateness.

Intervention Delivery (Years 2-3): Conduct a hybrid Type I effectiveness-implementation trial of Guardians 4 Health with up to 60 4-H Shooting Sports communities across the United States. For each intervention site, we will engage one Adult Site Champion in a kickoff meeting; provide materials to incorporate into standard 4-H curricula; and provide ongoing technical support. Evaluations will be conducted at 0, 3, and 6 months.
