RESUMEN
BACKGROUND: Dating violence in adolescence is a serious public health issue due to its significant impact on mental health and its significant predictive value for intimate partner violence in adulthood. Universal and selective programs can contribute to the prevention of this issue. Nonetheless, there are few selective programs with evidence of feasibility in contexts of social vulnerability. OBJECTIVE: The present study examined evidence of the feasibility of a dating violence selective prevention program for girls in foster care by monitoring process indicators during the implementation phase of a pilot study. METHODS: The program, originally designed for adolescents in the general population, was adapted to the context of girls at risk. The pilot study was conducted in the southern region of Brazil and involved the participation of six girls aged between 15 and 17. Both quantitative and qualitative measures were used, and the data were explored through frequency analysis, the Jacobson and Truax test, and content analysis. RESULTS: The study identified favorable evidence regarding demand, acceptability, and adaptation of the intervention. On the other hand, contextual and institutional barriers hindered recruitment and restricted the reach of the intervention. CONCLUSION: Although there are changes to be made to improve the program's applicability in its specific context, it should be emphasized that this study provides evidence to maintain the methods and content of the intervention.
