The purpose of this study was to assess the effect of an experiential, adventure-based "Anti-Bullying Initiative" on levels of resilience. The goal of this initiative was to create a more positive, caring, and safe learning environment for all students at a local elementary school in Santa Fe, New Mexico. Activities were designed to promote participants' resiliency skills, reduce bullying behavior, and create safer classroom environments. This study examined the effect of program participation on immediate changes in resilience, the enduring impact on resilience at 4 months post-treatment, and differences based on gender. In addition, this study sought to identify key program components that may have contributed to the observed changes.
