The Flint [Michigan] Adolescent Study (FAS): A Longitudinal Follow-Up Study of Substance Use on Adult Transitional Events, 2000-2003 collection includes data collected as part of four follow-up waves conducted for the Flint Adolescent Study (FAS). These data are waves five through eight, the original four waves can be found in ICPSR study 34598 (Flint [Michigan] Adolescent Study (FAS): A Longitudinal Study of School Dropout and Substance Use, 1994-1997.)

The Flint Adolescent Study (FAS) originally interviewed 850 ninth graders in the four public high schools of Flint, MI, between 1994 and 1997. Follow-up wave interviews were conducted four years after high school, between 2000 and 2003, as participants transitioned to young adulthood. The study was conducted in collaboration with the projects of Urban and Regional Affairs and Flint Community Schools. The goal of the study was to explore the protective factors associated with school dropout and alcohol and substance use. The study followed the youths for four years beginning in the Fall of 1994 to gather the first four waves of the study. The sample reflected the overall student body in the Flint high schools. In order to study those students most at risk for leaving school before graduation, individuals with grade point averages of 3.0 and below were selected.

Interviews were conducted face-to-face with each participant in a community location. Each interview took about one hour to complete. At the end of the interview students were asked to complete the last section of the questionnaire containing questions about their drug use and sexual behavior by themselves.

Information obtained from the participants include: participation in church and community organizations; social support and influence of family and friends; self-esteem and psychological wellbeing; delinquent and violent behaviors; alcohol and substance use; sexual behavior and child bearing; school attitudes and performance; and family structure and relationships. Many items included in the follow-up waves repeat those present in the original surveys. Questions were also asked about driving behavior, stress, and racial identity. Data was also collected about participant education and occupation.

Demographic variables in this collection include age, sex, race, education, occupation, employment history, residence type, household composition, height and weight, marital status, and number of children.

The National Longitudinal Study of Adolescent to Adult Health (Add Health), 1994-2018 [Public Use] is a longitudinal study of a nationally representative sample of U.S. adolescents in grades 7 through 12 during the 1994-1995 school year. The Add Health cohort was followed into young adulthood with four in-home interviews, the most recent conducted in 2008 when the sample was aged 24-32. Add Health combines longitudinal survey data on respondents' social, economic, psychological, and physical well-being with contextual data on the family, neighborhood, community, school, friendships, peer groups, and romantic relationships.

Add Health Wave I data collection took place between September 1994 and December 1995, and included both an in-school questionnaire and in-home interview. The in-school questionnaire was administered to more than 90,000 students in grades 7 through 12, and gathered information on social and demographic characteristics of adolescent respondents, education and occupation of parents, household structure, expectations for the future, self-esteem, health status, risk behaviors, friendships, and school-year extracurricular activities. All students listed on a sample school's roster were eligible for selection into the core in-home interview sample. In-home interviews included topics such as health status, health-facility utilization, nutrition, peer networks, decision-making processes, family composition and dynamics, educational aspirations and expectations, employment experience, romantic and sexual partnerships, substance use, and criminal activities. A parent, preferably the resident mother, of each adolescent respondent interviewed in Wave I was also asked to complete an interviewer-assisted questionnaire covering topics such as inheritable health conditions, marriages and marriage-like relationships, neighborhood characteristics, involvement in volunteer, civic, and school activities, health-affecting behaviors, education and employment, household income and economic assistance, parent-adolescent communication and interaction, parent's familiarity with the adolescent's friends and friends' parents.

Add Health data collection recommenced for Wave II from April to August 1996, and included almost 15,000 follow-up in-home interviews with adolescents from Wave I. Interview questions were generally similar to Wave I, but also included questions about sun exposure and more detailed nutrition questions. Respondents were asked to report their height and weight during the course of the interview, and were also weighed and measured by the interviewer.

From August 2001 to April 2002, Wave III data were collected through in-home interviews with 15,170 Wave I respondents (now 18 to 26 years old), as well as interviews with their partners. Respondents were administered survey questions designed to obtain information about family, relationships, sexual experiences, childbearing, and educational histories, labor force involvement, civic participation, religion and spirituality, mental health, health insurance, illness, delinquency and violence, gambling, substance abuse, and involvement with the criminal justice system. High School Transcript Release Forms were also collected at Wave III, and these data comprise the Education Data component of the Add Health study.

Wave IV in-home interviews were conducted in 2008 and 2009 when the original Wave I respondents were 24 to 32 years old. Longitudinal survey data were collected on the social, economic, psychological, and health circumstances of respondents, as well as longitudinal geographic data. Survey questions were expanded on educational transitions, economic status and financial resources and strains, sleep patterns and sleep quality, eating habits and nutrition, illnesses and medications, physical activities, emotional content and quality of current or most recent romantic/cohabiting/marriage relationships, and maltreatment during childhood by caregivers. Dates and circumstances of key life events occurring in young adulthood were also recorded, including a complete marriage and cohabitation history, full pregnancy and fertility histories from both men and women, an educational history of dates of degrees and school attendance, contact with the criminal justice system, military service, and various employment events, including the date of first and current jobs, with respective information on occupation, industry, wages, hours, and benefits. Finally, physical measurements and biospecimens were also collected at Wave IV, and included anthropometric measures of weight, height and waist circumference, cardiovascular measures such as systolic blood pressure, diastolic blood pressure, and pulse, metabolic measures from dried blood spots assayed for lipids, glucose, and glycosylated hemoglobin (HbA1c), measures of inflammation and immune function, including High sensitivity C-reactive protein (hsCRP) and Epstein-Barr virus (EBV).

Wave V data collection took place from 2016 to 2018, when the original Wave I respondents were 33 to 43 years old. For the first time, a mixed mode survey design was used. In addition, several experiments were embedded in early phases of the data collection to test response to various treatments. A similar range of data was collected on social, environmental, economic, behavioral, and health circumstances of respondents, with the addition of retrospective child health and socio-economic status questions. Physical measurements and biospecimens were again collected at Wave V, and included most of the same measures as at Wave IV.

The overall goal of Wave VI was to better understand life course trajectories, determinants, and consequences of critical dimensions of aging, health, and health disparities among U.S. early midlife adults. Data collection took place from 2022 to 2025, with participants between the ages of 39 and 51, with an average age of 44. Beyond longitudinal survey measures, newly added questions included those on cumulative stress, discrimination, despair, work-life balance, memory, physical limitations, and caregiving. Continuing from previous waves, home exams collected physical measurements and biospecimens with most of the same measures as Wave V.

The Youth Development Study (YDS) was initiated as a school-based study of adolescent children and their parents to examine the consequences of formative experiences in adolescence for mental health, value formation, educational achievement, and multiple facets of behavioral adjustment. Particular attention was directed to the impacts of early work experience. Data were also obtained about parent-child and peer relationships and experiences in school. As the study continued, the focus shifted to adult development and attainment and, most recently, mid-life adjustment and health. This comprehensive longitudinal study now encompasses three generations: the initial cohort studied from adolescence to mid-life (G2), their parents (G1), and their adolescent children (G3). Data from three generations in the same families enable study of intergenerational relationships and differences in the experience of adolescence and transition to adulthood across parent and child cohorts. The YDS covers a wide range of topics of interest to sociologists, social psychologists, developmental psychologists, and life course scholars, including the development and impacts of agentic resources, socioeconomic attainment, processes of inter- and intra-generational mobility, objective and subjective work conditions, family relationships, intergenerational relationships, mental and physical health, and well-being.

In-school administration of paper surveys during the first four years of the study was supplemented by mailed surveys. Subsequent data collection took place entirely by mail, with 19 surveys conducted between 1988 and 2011. A final survey was conducted on-line in 2019. Survey data was obtained from the parents (G1) of this cohort during the first and fourth waves of the study (1988 and 1991). Surveys of the children (G3) began in 2009, continued in 2010 and 2011 (by mail) and in 2019-2020 (online).

The Youth Development Study measures a wide range of formative experiences and both psychological and behavioral variables, using survey methodology.

The G1 surveys obtained information about socioeconomic background as well as attitudes toward teenage employment, the parents' own employment as teenagers, their current work experiences, and educational expectations for their children.

The G2 surveys during the high school years included detailed questions about students' work and volunteer experiences, as well as experiences in their family, school, and peer groups, with an emphasis on the ways that working affected other life domains, mental health, and well-being. Shorter surveys containing many of the same topics were administered to students in 1992, 1993, and 1994, and included questions about current family and living arrangements. In 1995, a full survey was administered covering the wide range of topics included in previous surveys as well as information about career plans and life events that had occurred in the past five years. G2 Waves 9 through 19 (1997-2011) included many of the same questions contained in earlier surveys and additional sections that focused on the respondents' educational experiences, family relationships, sources of living expenses, and health and well-being. The most recent G2 survey (2019), administered on-line, included questions about support of aging parents. The YDS is unique in its coverage of both objective and subjective work experiences from adolescence to mid-life.

The topics covered by the G3 surveys are very similar to the G2 variables described above. Variables in each G2 and G3 wave are included in cross-wave codebooks, available at the Data Archive Codebook website.
