 This study will answer two questions: 1 do factors that predict sexual risk taking and its precursors in young adolescence operate similarly in middle childhood; and 2 can interventions shown to be effective in early adolescence be developmentally adapted for middle childhood to delay sexual initiation and its precursors? The study will evaluate the impact of the intervention on mechanisms hypothesized to reduce sexual risk taking and its precursors, including the personal resiliency and social competencies of youth. The study will also collect data on the costs and process of implementation to inform subsequent dissemination.
