  Special Topics in Firearm Injury Prevention Posters Authors: Adrianne Ka

 Background Firearm injury is the leading cause of death for American yout
 h ages 1-17\, yet few interventions have been co-created with gun-owning 
 communities. Bystander interventions that teach youth to identify risky s
 ituations and respond safely to prevent injury are well-suited for youth 
 that have contact with firearms\; and have shown to be effective in preve
 nting youth violence in other settings. In partnership with 4-H Shooting 
 Sports (4HSS) leadership\, we developed and tested a novel firearm injury
  prevention (FIP) bystander intervention\, “Guardians 4 Health” (G4H)\, f
 or delivery to youth ages 12-18. The primary outcome objective of this st
 udy was to measure the impact of the G4H intervention on intention to use
  bystander intervention strategies.Methods: We conducted a cluster-random
 ized Type 1 Hybrid Effectiveness-Implementation trial\, stratified at ran
 domization by rurality and state Child Access Prevention (CAP) laws\, con
 senting 4HSS sites\, parents\, and youth. With confirmed construct validi
 ty\, we aggregated two items measuring bystander intervention intention a
 cross five hypothetical scenarios to create one continuous outcome variab
 le assessed at 0\, 3- and 6-months. Using intention-to-treat approach\, w
 e applied linear mixed models adjusting for baseline outcomes\, then perf
 ormed multilevel multiple imputation accounting for the potential within-
 site correlation in missingness\, with covariate adjustment on baseline o
 utcomes and sociodemographic backgrounds. Finally\, we conducted subgroup
  analyses for select sociodemographic groups. Results Fifty 4HSS sites fr
 om 28 states were randomized to intervention (M = 26 sites\; N = 250 yout
 hs) or control (M = 24 sites\; N = 174 youths). Most youth were aged 12-1
 4 (54.7%)\, male (53.3%)\, and White (68.2%). Most caregivers had at leas
 t some college education (68.3%)\, were married (73.0%)\, and employed (5
 6.4%). Compared to control youth\, G4H youth had more participants aged 1
 2–14 years (61.9% vs. 47.9%\, p = 0.007). Racial composition varied (p = 
 0.022)\, with the intervention group having a higher proportion of White 
 participants (p=0.02). At 3 months\, bystander intervention intention was
  higher in G4H than in control youth (β = 0.13\, 95% CI: [0.03\, 0.24]) b
 ut not significant at 6 months (β = 0.10\, 95% CI: [-0.02\, 0.22]). At 3 
 months\, younger participants (12–14 years) showed a stronger interventio
 n effect than older adolescents\, and responses were stronger among those
  whose parents had lower education (high school)\, were unemployed\, non-
 veterans\, and unmarried. Conclusions To our knowledge\, this is the firs
 t national trial focused on FIP occurring through partnership between a s
 hooting sports organization and public health researchers\, and the first
  to use bystander intervention for FIP in youth. At 3 months post-interve
 ntion\, we observed a positive effect on behavioral intention\, a strong 
 predictor of behavior. These findings provide initial support for the val
 ue of the G4H intervention within 4HSS\, with continued evaluation in lar
 ger samples and other settings warranted.\n\nSpeakers:\nAdrianne Katrina
