National Longitudinal Study of Adolescent Health (Add Health) (ICPSR 183)

Principal Investigator(s): Udry, Richard J., University of North Carolina-Chapel Hill. Carolina Poulation Center


National Longitudinal Study of Adolescent Health (Add Health) is a study of a nationally representative sample of more than 20,000 individuals that began with in-school questionnaires administered to adolescents in grades 7-12 in the United States in 1994-95, followed by three waves of in-home interviews in 1995, 1996, and 2001-02. Information on these individuals covers the adolescent years and their transition to adulthood. These data allow study of the ways social contexts (families, friends, peers, schools, neighborhoods, and communities) influence adolescents' health and risk behaviors. Data at the individual, family, school, and community levels were collected in two waves between 1994 and 1996. In 2001 and 2002, Add Health respondents, 18 to 26 years old, were re-interviewed in a third wave to investigate the meaning of adolescence for health and well-being outcomes in young adulthood.
