National Longitudinal Study of Adolescent Health (Add Health), new restricted data

The National Longitudinal Study of Adolescent Health (Add Health) has released several new waves of data.

Add Health is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-1995 school year. The Add Health cohort has been followed into young adulthood with three in-home interviews, the most recent in 2001-2002, when the sample was aged 18-26. 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, providing unique opportunities to study how social environments and behaviors in adolescence are linked to health and achievement outcomes in young adulthood.

These are:
1994-2002: Wave III Alcohol Outlet Density
This Add Health data file measures the prevalence of alcohol outlets in respondent communities by reporting the tract-level density of establishments possessing on- and/or off-premise alcohol licenses. Alcohol outlet licensing data was gathered from individual states from September 2006 through June 2007. The physical address and the alcohol license category for each outlet were obtained when available.

1990-2004: Political Context Database
The Add Health Political Context Database provides an array of measures that describe the political environments in which Add Health respondents reside and, thereby, enables researchers to explore the role of certain contextual influences on adolescent and early adult political behaviors.

1994-2002: Medication Files
The files contained in this component of the Add Health restricted data include the type of medication used by participants during Wave IV.

These are restricted use data, and users must complete a restricted use agreement in order to use the data.  The Libraries’ Secure Data Facility can be used to as a secure location to host the data once acquired by the researcher.
