Personal Responsibility Education Program (PREP) Multi-Component Evaluation, Impact Study, 4 U.S. states, 2013-2018

The Personal Responsibility Education Program (PREP) Multi-Component Evaluation impact study aimed to expand the available evidence on effective approaches to teen pregnancy prevention, especially among high-risk youth. The study conducted independent rigorous impact evaluations in four PREP-funded sites - Iowa, Kentucky, New York, and Texas. Each site implemented a different teen pregnancy prevention program, offered services to a distinct target population, and operated in a different geographic area of the country. The sample enrollment periods, random assignment procedures, data collection schedules, and key outcomes of interest also varied across sites. The impact study addressed questions about programs' successes in reducing adolescent pregnancy, sexually transmitted infections, or associated sexual risk behaviors; pathways or mechanisms through which the programs work, and how program impacts vary by levels of program participation. In each site, the study data collection included a baseline survey conducted at sample enrollment. Three of the sites had two rounds of follow-up surveys that were conducted about one and two years later, and one site had only one follow-up survey, which was conducted about six months after program completion.
