Abstrakt: Objectives: To test the effectiveness of Reducing the Risk, an evidence-based sexual health curriculum designed to help prevent adolescent pregnancy and sexually transmitted infections, on youth sexual behavior and intermediate outcomes thought to lead to these behaviors.
Methods: Classes within schools in St. Louis, Missouri; Austin, Texas; and San Diego, California; were randomly assigned to receive Reducing the Risk or "business as usual." Youths completed Web-based surveys at baseline (preintervention, August 2012-January 2014) and 12 months later (August 2013-January 2015). Intent-to-treat analyses were conducted across sites; we tested for differences in impacts between sites and other subgroups.
Results: The program had no overall impact on sexual behaviors. However, at 1 site, program participants were significantly less likely to have engaged in recent sexual intercourse than were control group members. There were positive overall impacts on intermediate outcomes (e.g., knowledge, attitudes).
Conclusions: After 12 months, Reducing the Risk was unsuccessful at changing sexual behaviors. Other results were mixed, but promising evidence (e.g., behavioral impacts at 1 site, impacts on intermediate outcomes) suggests potential for more widespread behavioral impacts over a longer term.
