This study examined whether participation in an adventure program increased the resiliency of adolescent girls. Eighty-seven girls who participated in Dirt Divas, a non-profit, adventure program, completed the Resiliency Scale for Children and Adolescents® before and after their experience. Means-comparison tests for within-subjects designs were conducted and revealed that participants reported significantly higher levels of resilience after completing the Dirt Divas program, compared with their pre-program reports. Mixed-model repeated-measures analyses of variance showed that the changes in the girls' resiliency were not affected by their socioeconomic status. Lastly, the long-term impact results (one month post participation) indicate that observed increases in resilience persist over time.
