description: 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.

description: Four impact study sites were selected to advance current understanding of effective approaches to teen pregnancy prevention by filling specific, targeted gaps in the existing research evidence. Sites were selected based on the feasibility of conducting a random assignment impact evaluation and each prospective site's value in advancing available evidence on effective approaches to teen pregnancy prevention. The evaluations of the four PREP impact study sites were designed to be distinct and independent; each site was implementing a different teen pregnancy prevention program, offered services to a distinct target population, and operated in a different geographic area of the country. Two of the sites assigned eligible students (with parental consent) to a treatment status using stratified random assignment of students within schools, one site used stratified random assignment of schools (clusters), and one site used rolling random assignment of individual adolescents. In each site, a baseline survey of both treatment and control group members was conducted at sample enrollment. At three sites, two or one follow-up surveys were conducted after program completion.
description: Response Rates: Response rates varied across surveys and sites from 81 to 100 percent.
description: By study site, the four target groups were identified: Boys in 7th grade in Davenport, Iowa; Rural high school students in Kentucky. At-risk youth in grades 7 to 12 attending alternative schools in the greater New York City metropolitan area; Adolescent mothers ages 14 to 20 in San Angelo, Texas;
