 Familias Unidas is delivered through family-centered, multi-parent groups that place parents in the change agent role and through family visits. Each parenting skill is discussed and role-played in parent-group sessions and is then enacted with the parent and the adolescent in a family visit. During the group sessions, the facilitator offers support for parents and gently corrects maladaptive interactions between parents and adolescents during the group-session role plays, the role of adolescent is played by another parent. During family visits, facilitators assist families in practicing skills and restructuring family interactions. The parent group sessions focus on parental investment in the adolescents worlds e.g., peer and school worlds, family communication, family support, behavior managementpositive parenting, parental monitoring, adolescent substance use, and adolescent unsafe sex and HIV. Consistent with our prior Familias Unidas efficacy studies, all parent group sessions and all family visits will be conducted in Spanish and will take place in the evenings and on Saturdays at the school or at a community site that is preferred by the families.
