Teen Pregnancy Prevention

Systematic Reviews

TPP Replication Study Findings

The Teen Pregnancy Prevention (TPP) Replication Study (2010-2015) was an experimental study that examined the implementation and impact of three replications of three evidence-based program models: Reducing the Risk, ¡Cuídate!, and Safer Sex. The study examined whether program models that were commonly chosen by TPP grantees and widely used in the field could achieve impacts with different populations and settings. Read the study overview, design reports, site profiles, and findings briefs and reports on the TPP Replication Study page.

Economic Evaluation of Select Evidence-Based TPP Programs

Adolescent Pregnancy Prevention Approaches Study

The Evaluation of Adolescent Pregnancy Prevention Approaches study (2008-2016) was an experimental study that assessed the implementation and impact of seven innovative strategies and untested approaches for preventing teenage pregnancy. There are three TPP Research and Demonstration grantees (Tier 2), three ACYF Personal Responsibility Education Program Innovative Strategies (PREIS) grantees, and one non-federally funded program included in the evaluation. Read the site implementation and impact reports as well as a final report and fact sheet on the Adolescent Pregnancy Prevention Approaches Study page.

Sustainability Study of Former TPP Programs Results

The Sustainability Study of Former TPP Programs (2015-2018) examined how former TPP programs funded by OAH (now OPA) sustained their work after federal funding ended. The study focused on a total of 71 former grantees who were not awarded renewed funding in the TPP program and PAF program. Get lessons learned and case study reports on the Sustainability Study of Former TPP Programs page.

Meta-Analysis of Federally Funded TPP Programs

The Meta-Analysis of Federally Funded TPP Programs (2015-2019) looked at findings from over 40 studies to learn about teen pregnancy prevention from federally-funded programs that have already been evaluated. The study provided a look at what existing evaluations suggest about how the types of programs, the ways they do their work, and the participants they draw work together to reduce teen pregnancy. Get the project description, design and analysis plan, research brief, final report, and technical supplement on the Meta-Analysis of Federally Funded TPP Programs page.

FY2010-2014 Program Evaluation Reports 

The Fiscal Year 2010-2014 TPP grant types that were rigorously evaluated were (1) replications of evidence-based programs to prevent teen pregnancy and/or associated sexual risk behaviors; and (2) new and innovative programs to prevent teen pregnancy. Study designs included random assignment and high-quality quasi-experimental evaluations. Read the program evaluation reports on the Grantee Evaluations FY2010-2014 page.
