This study contains data from the third follow-up interview of the Northwestern Juvenile Project (NJP), a longitudinal assessment of alcohol, drug, or mental service treatment needs of juvenile detainees. The third follow-up occurred approximately four 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. A random subsample of 997 of the baseline participants were chosen for third follow-up interviews. 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. Data from the first follow-up (conducted approximately three years after the baseline) and second follow-up (conducted approximately three and a half years after the baseline) were deposited with ICPSR's National Archive of Criminal Justice Data.
A random subsample of participants was scheduled for a third follow-up interview approximately 4 years after their baseline interview (Follow-up 3). 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:
Detainees were eligible to be sampled regardless of their psychiatric morbidity, state of drug or alcohol intoxication, or fitness to stand trial. Within each stratum, the project used a random-numbers table to select names from Cook County Juvenile Temporary Detention Center's intake log. The final sampling fractions ranged from 0.018 to 0.689.
The third follow-up was conducted approximately 4 years after the baseline with a random subsample.
Male and female juvenile detainees, ages 10 to 18, at intake to the Cook County (IL) Juvenile Temporary Detention Center (CCJTDC) between November 20, 1995 and June 14, 1998.
Follow-up 3 consists of 23 data files. Follow-up interview data are stored in separate datasets corresponding to each interview module.
By 6 years after their baseline interview, 856 participants had received a Follow-up 3 interview. Fifty-eight participants received Follow-up 3 interviews more than 6 years after their baseline interview. Other reasons for non-response at Follow-up 3 were: died before the 6-year cut-off (n=14); withdrew from the study (n=17); and could not be located (n=52).

2017-07-06 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 da36651-0001.
Users who plan on analyzing KBIT scores should apply survey weights (kbit_WT, kbit_wt) that are designed to account for the presence of scores from both Follow-up 1 and Follow-up 3 interviews in the dataset. These weighting variables can also be found in dataset da36651-0001.
HideThe public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

This dataset is maintained and distributed by the National Archive of Criminal Justice Data (NACJD), the criminal justice archive within ICPSR. NACJD is primarily sponsored by three agencies within the U.S. Department of Justice: the Bureau of Justice Statistics, the National Institute of Justice, and the Office of Juvenile Justice and Delinquency Prevention.
