Northwestern Juvenile Project: Archiving Data, Part I

This program furthers the Department's mission by providing grants and cooperative agreements for research and evaluation activities to organizations that OJJDP designates.

The Northwestern Juvenile Project (NJP) is the first large-scale, longitudinal study of alcohol, drug, and mental health service needs and outcomes of youth involved in the juvenile justice system. The overall sample of 1829 youth is racially/ethnically diverse and includes 1172 males and 657 females, 10 to 18 years of age at baseline, who were arrested and detained between 1995 and 1998 in Cook County (Chicago), Illinois. Since 1995, participants have been tracked and re-interviewed, whether they are back in their communities or (re)incarcerated, resulting in a longitudinal data set spanning over 15 years.

This application proposes to continue to archive data from the NJP to make them available to a larger community of researchers. Data from the baseline interview were recently deposited to the National Addiction and HIV Data Archive Program (NAHDAP) at the Interuniversity Consortium for Political and Social Research (ICPSR). The NJP researchers are in the process of preparing data from the first follow-up interview for deposit in the National Archive of Criminal Justice Data (NACJD). This continuation application proposes to prepare and deposit interview data from the second and third follow-up interviews, 3.5 and 4 years after baseline, to the NACJD.

The NJP researchers are in the process of preparing data from the first three follow-up interviews for deposit in the National Archive of Criminal Justice Data (NACJD). This application proposes to prepare and deposit interview data from the fourth follow-up interview, 4.5 years after baseline, to the NACJD.

More recently, data from the first three follow-up interviews were deposited to the National Archive of Criminal Justice Data (NACJD); the research team is completing the process of depositing data from the fourth follow-up interview. This application proposes to prepare and deposit selected data from the fifth and sixth follow-up interviews, 6 years and 8 years after baseline, to the NACJD.
