Evaluation of Adolescent Pregnancy Prevention Approaches: Design of the Impact Study (Executive Summary)

The Evaluation of Adolescent Pregnancy Prevention Approaches (PPA) is a major federal effort to expand available evidence on effective ways to prevent and reduce pregnancy and related sexual risk behaviors among teens in the United States. The eightyear (2008–2016) evaluation is being conducted by Mathematica Policy Research and its partners, Child Trends and Twin Peaks Partners LLC, under contract to the Office of Adolescent Health (OAH) in the Office of the Assistant Secretary for Health of the U.S. Department of Health and Human Services (HHS). The evaluation will document and rigorously test promising pregnancy prevention approaches in seven sites across the United States, each of which will implement a different program.
