Version V1

This data collection consists of six parts and 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.

The first four datasets in this collection can be linked using the linking variables B_STNU and PAB_STNU or PRB_STNU.

The study sought to gather data to evaluate the effectiveness of Adolescent Family Life (AFL) demonstration program. This program supported prevention demonstration projects to develop, test, and use curricula providing sexuality education to delay the onset of youth sexual activity and reduce the incidence of pregnancy and sexually transmitted diseases (STDs).

The Prevention data only includes data from projects with experimental or quasi-experimental local evaluation designs. Researchers used a matched-group design involving 30 schools and community sites across the six grantees. Based on geographic and demographic characteristics, schools receiving AFL-funded abstinence programming or abstinence plus enhanced programming (such as parent workshops or after-school programs) were matched with those receiving standard curricula or abstinence education. Longitudinal data were collected from treatment and comparison youths before program activities began (from August 2008 to November 2009) and at approximately 1-year follow-up (from April 2009 to November 2010).

The participants in this study were a convenience sample of participants in selected Adolescent Family Life demonstration projects in 14 states across the country. A total of 2,644 youths in Prevention projects and 1,037 adolescents in Care projects completed a baseline survey; follow-up rates were 83 percent for Prevention and 76 percent for Care.

Treatment group

survey data

This collection contains a total of six parts and 1,053 variables.

  • Parts 1 and 5: data relating to the AFL program site, such as the location of services, services rendered, caseworker caseload, and how frequently students participate in the program.
  • Parts 2, 3, 4 and 6: baseline and follow-up information on teenage parents, pregnant teens, and teens' views on preventing pregnancy. Parts 2 and 4 include variables relating to children's immunization data, and examine the parent's attitudes towards education, their future, marriage and relationships, birth control methods, and child care options. Parts 3 and 6 contain data relating to birth control methods, attitudes towards sex, marriage, and friends, living situation, and their relationship(s) with their parent(s) or someone who is like a parent. Parts 2 through 4 and part 6 contain demographic variables which include gender, age, and education level.

For the Prevention group, of the 5,994 consent forms distributed, 3,067 parents, or 51 percent, consented to their youths' participation in the cross-site evaluation. The baseline survey was administered to this group, with 2,644 (1,542 in the treatment group and 1,102 in the comparison group) or 86 percent completing the baseline. This group received the follow-up survey, and 83 percent of teens who completed the baseline survey completed the follow-up. For the Care group, 1,157 teens were granted consent to participate, which represents 79 percent of those asked to participate. The youths with consent were given the baseline survey, and 1,037 (90 percent) of those completed the baseline (508 were from the intervention group and 529 from the comparison group). Finally, 76 percent of those who completed the baseline survey (794 teens) completed the follow-up survey.

A Likert scale is used throughout.



2015-09-03 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created variable labels and/or value labels.
  • Checked for undocumented or out-of-range codes.

The data are not weighted and no weight variables are present in the collection.
