Project Goal: The study sought to test and refine a parent-based intervention designed to prevent adolescent sexual risk behavior in Latino and African American inner-city populations. The intervention used a novel outreach approach relative to extant parent-based interventions. Specifically, the intervention took place in a primary healthcare clinic and was coordinated through allied health professionals when physicians see adolescents for their annual physical examinations. The overall goal of the research program was to further develop and evaluate a practical, effective, and cost-efficient parent intervention that can be used in healthcare settings.
