No research has explored the potential of homeless youth to serve as gatekeepers for suicide prevention purposes. This study described and examined associations between gatekeeping beliefs (i.e. preparedness and efficacy), intent-to-intervene, and gatekeeping behaviors (approach/referral behavior). In a sample of 139 homeless youth (aged 14-24), regression analysis was used to characterize associations between gatekeeper beliefs, intent, and behaviors. On average, participants engaged in gatekeeper behaviors with 1-2 people over the past 3 months. Gatekeeping beliefs and intent were positively associated with behaviors. Gatekeeper training that targets these attributes is a promising prevention strategy for homeless youth, but may require population-specific adaptation.
