Reducing Teen Pregnancy: Generating Evidence about Replicating Prevention Programs


  • Are teen pregnancy interventions movable from one area to another?
  • Abt-led evaluation tries to answer that question using three models
  • Preliminary findings show all three models have benefits
The Challenge

U.S. schools and communities have launched numerous efforts to reduce teen pregnancy, births to teens and sexually transmitted infections. But will interventions that worked in one place work in another locale with a different population?

The Approach

An Abt-led evaluation tries to answer that question using three models:

  1. Reducing the Risk, a sex education curriculum in schools
  2. The clinic-based Safer Sex Intervention for sexually active young women
  3. A culturally relevant curriculum for Latino youth, ¡Cuídate!


The project funded three grantees to replicate each model (there are nine grantees altogether). Data collection occurred at three points: when youth enrolled; between 6 and 12 months after random assignment; and between 18 and 24 months after random assignment.

The Results

The contract ends in September 2018, so a final report is not available. But preliminary findings show that:

  • Reducing the Risk did not change sexual behavior, but did demonstrate positive impacts on knowledge about and attitudes toward sexual risk behavior and protection
  • The Safer Sex Intervention produced significant changes in sexual behavior and sexual risk behavior
  • ¡Cuídate! had no impact on sexual behavior but improved knowledge and attitudes
