This study contains data from the first follow-up interview of the Northwestern Juvenile Project (NJP), a longitudinal assessment of alcohol, drug, or mental service treatment needs of juvenile detainees. This initial follow-up occurred approximately three years after the baseline interview and focused on studying the development and persistence of psychiatric disorders, related predictive variables, patterns of drug use, and other risk behaviors.
The project's aims included studying (1) development and persistence of alcohol, drug, and mental disorders and (2) pathways and patterns of risky behaviors. Changes in disorders over time were studied (including onset, remission, and recurrence), comorbidity, associated functional impairments, and the risk and protective factors related to these disorders and impairments. This study addressed patterns and sequences of the development of drug use and related variables, focusing on gender differences, racial/ethnic differences, the antecedents of these risky behaviors (risk and protective factors), and how these behaviors were interrelated.
The original sample included 1829 randomly selected youth, 1172 males and 657 females, then 10 to 18 years old, enrolled in the study as they entered the Cook County Juvenile Temporary Detention Center from 1995 to 1998. Among the sample were 1005 African Americans, 524 Hispanics, 296 non-Hispanic white respondents. Participants were tracked from the time they left detention. Re-interviews were conducted regardless of where respondents were living when their follow-up interview was due: in the community, correctional settings, or by telephone if they lived farther than two hours from Chicago.

The project's aims included studying (1) development and persistence of alcohol, drug, and mental disorders and (2) pathways and patterns of risky behaviors. Changes in disorders over time were studied (including onset, remission, and recurrence), comorbidity, associated functional impairments, and the risk and protective factors related to these disorders and impairments. This study addressed patterns and sequences of the development of drug use and related variables, focusing on gender differences, racial/ethnic differences, the antecedents of these risky behaviors (risk and protective factors), and how these behaviors were interrelated. The development and persistence of alcohol, drug, and mental disorders of delinquent youth are examined. Data from the baseline interview were deposited at the National Addiction and HIV Data Archive Program with the Inter-University Consortium for Political and Social Research.
All participants were scheduled for follow-up interviews approximately 3 years after their baseline interview. Participants were tracked until they were found for an interview, withdrew, or were known to have died. Some participants who were difficult to locate received their follow-up interviews substantially later than the planned interview dates.
Follow-up interviews were conducted face-to-face wherever the participant was living--in the community or in any correctional facility in Illinois--at the time their interview was due. However, community interviews were conducted by telephone if the participant lived more than 2 hours away. Diagnostic modules were administered via pencil and paper interviewing (PAPI) or computer assisted personal interviewing (CAPI). Non-diagnostic modules were administered via PAPI.
A stratified random sample of 1,829 youth at intake from Cook County Juvenile Temporary Detention Center (CCJTDC) in Chicago, Illinois, was recruited between November 20, 1995, and June 14, 1998. This baseline sample was stratified by gender, race/ethnicity (African American, non-Hispanic white, Hispanic, "other" race/ethnicity), age (10-13 years or 14 years and older), and legal status (processed in juvenile or adult court) to obtain enough participants to examine key subgroups (e.g., females, Hispanics, younger persons). There were a total of 13 strata, as listed below. There were too few female detainees of each race/ethnicity and detainees identified as "other" race/ethnicity to further stratify these groups. Detainees aged 10 to 13 years were not stratified by legal status because they were generally too young to be considered for transfer to adult court.
Sampling Strata:
Youth at intake to the Cook County Juvenile Temporary Detention Center (CCJTDC) in Chicago, Illinois, between November 20, 1995, and June 14, 1998.
Follow-up 1, consists of 22 data files. Follow-up interview data are stored in separate datasets corresponding to each interview module.
By 4.5 years after their baseline interview 1659 participants had received a Follow-up 1 interview. Ninety-two participants received Follow-up 1 interviews more than 4.5 years after their baseline interview. Other reasons for nonresponse at Follow-up 1 were: died before the 4.5-year cut-off (n=31); withdrew from the study (n=5); and could not be located (n=42).

2017-04-14 2016-12-07 Updated the study datasets 9, 10, 13,14, and 18 to add/modify value labels where appropriate. In dataset 14 some computed variables were dropped from the file. Codebooks for all datasets in the study were updated.
2016-11-11 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:
Follow-up weights are sampling weights augmented with adjustments for nonresponse (e.g., withdrew, died) at the follow-up. Sampling weights and normalized sampling weights are also provided in dataset da34931-0001.
T_WT is a sample case weight, T_WT0 is a sample normalized weight of the total sample (n=1751). CUTOFF_WT is a case weight that excludes interviews that occurred more than 18 months after the scheduled interview date (or 4.5 years after baseline) and CUTOFF_WT0 is a normalized weight with a 4.5 year cut-off (n=1659).
