Contains data collected from projects funded through Title XX, the Adolescent Family Life (AFL) program. A cross-site evaluation of the AFL program was conducted to describe the implementation of AFL projects and evaluate their impact on key outcomes. Baseline surveys were completed by 2,644 youths in 6 Prevention projects across 6 states and 1,037 adolescents in 12 Care projects across 10 states. A total of 13 states and the District of Columbia were included in the study. Prevention respondents completed a follow-up survey approximately 1 year after baseline. Care respondents who were pregnant at baseline completed follow-up surveys approximately 6 and 12 months after the birth of their child, and Care respondents who were parenting at baseline completed follow-up surveys approximately 1 year after baseline. The goal was to obtain information about demonstration projects to develop, test, and use curricula providing sex education to delay the onset of youth sexual activity and thus reduce the incidence of pregnancy and sexually transmitted diseases. The study sought to answer both process and outcome evaluation questions to determine whether the AFL program had desired effects on adolescents served. Topics covered include adolescent attitutes towards relationships and sexual behavior, birth control, and communication with parents and peers. Demographic variables also include gender, age, and education level.
