Considering the increased risk of revictimization, adolescents who have experienced child sexual abuse (CSA) are a priority subpopulation for the prevention of dating violence. Yet, intervention programs often focus on psychological symptomology associated with CSA; few tackle issues specific to relational violence. Addressing the relational traumatization of adolescents with a history of CSA is essential to prevent their revictimization. Given specific CSA sequelae related to intimacy and engagement in sexual behaviors, there is a need for tailoring interventions to boy and girl survivors. A case study of a group intervention designed for adolescent girls with a history of CSA was conducted. The context adaptation, based on intervention mapping proposed by Bartholomew and colleagues, served as a theoretical framework. Four steps were taken to ensure that the intervention addressed CSA youth needs: (a) needs assessment, (b) analysis of the conceptual framework of the original program, (c) selection of interventions and developing new interventions, and (d) validation with a committee of practitioners. This approach provided an understanding of risk factors and intervention priorities using the problem logic model. The original program was enhanced by adding four interventions addressing the prevention of dating violence. These interventions were then validated by practitioners before implementation in the setting. The approach underscores the relevance of understanding the needs of the clientele and of adopting a collaborative approach to ensure the proposed interventions are relevant.
