Rural adolescents are at risk for firearm-related injury and death. In response, professional organizations have called for communication between adolescents, parents, and providers about firearms. A shared understanding of firearms between providers and families can facilitate effectiveness of health interventions. However, few studies engage adolescents in identifying their perception of common firearm terminology. The current study aimed to understand how adolescents in rural communities defined firearm-related terms including firearm, carrying, and handling, and differences in terms based on prior firearm training. Data were from a mixed methods community-based participatory study of 93 adolescents from rural Washington state. Thematic qualitative coding identified themes for firearm (gun, weapon, projectile, and tool), carrying (on you/your person, transportation, and holding), and handling (actively using, safe use, and holding) and differences between those with prior firearms training. Findings provide insight into perceptions of firearm-related terms for adolescents, an often-neglected voice, and inform rural policy and prevention efforts.
