Childhood victimization can negatively affect children’s self-perception, a multifaceted developmental asset that can be delineated into Global Self-Worth, Social Competence, and Behavioral Conduct. Despite the importance of self-perception, few studies have examined how strengths-based interventions impact self-perception among youth experiencing victimization. Using a familial case study design, the current study evaluated how a camp-based intervention, known as Camp HOPE, affected self-perception among siblings who experienced childhood victimization. Participants included three siblings and their mother who all identify as Black/African American and reside in the Midsouth, United States. The siblings participated in a week-long, overnight camp with other children exposed to victimization. The family was evaluated across three timepoints: pre-camp, 1 month post-camp, and 4 months post-camp. Participating in Camp HOPE appeared to have differential effects on the siblings’ self-perception. Specifically, all three children endorsed small to medium improvements in perceived Behavioral Conduct, but the camp differentially impacted their Global Self-Worth and Social Competence. Findings suggest that Camp HOPE may enhance self-perception among Black/African American children who have experienced victimization. This intervention may also be more accessible and acceptable, compared to traditional treatment formats.
