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.

- African American males, aged 10-13 years

Longitudinal: Panel: Continuous
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.
- The main dataset (MAIN) includes administrative information on; what measures were conducted, the location of and type of interview, interview date and age of respondent at interview. This dataset (da34931-0001) has 21 variables, 1829 observations.
- The interviewer comments (COMMENTS) asked the interviewer to record their observations of how participants managed the interview, including whether participants had any difficulties with particular measures, whether participants seemed to be truthful, and whether the participant exhibited any psychotic symptoms. Interviewers filled out this observational measure following the interview. The dataset (da34931-0002) includes 64 variables, 1748 observations
- The Child and Adolescent Functional Assessment Scale (CAFAS) includes multidimensional measurements of functional impairment and scales of role performance, behavior toward others, mood, self-harmful behavior, substance use, and thinking. This dataset (da34931-0003) includes 37 variables and 1747 observations.
- The Child and Adolescent Services Assessment - Modified (CASA-M) probes dimensions of service use for each mental health or substance abuse service. Dimensions include reason for services, type of treatment, frequency and duration of the service, referral sources, pathways to services, and attitudes and barriers to treatment. There are 5 data files associated with this module: da34931-0004 (387 variables, 1736 observations) refers to the school services screener, da34931-0005 (57 variables, 247 observations) refers to non-school services screen, da34931-0006 (62 variables, 284 observations) refers to services provided in addition to mental health services from da34931-0004 and da34931-0005, da34931-0007 (134 variables, 829 observations) refers to the referral source for the mental health services, and da34931-0008 (128 variables, 826 observations) refers to subject's attitudes and barriers to treatment.
- The Child and Family Assessment (CFA) assesses risk and protective factors for psychopathology as well as actors related to initiation, escalation, and desistance of delinquency and violence. Variables included cover: demographic assessment, medical screen, family functioning assessment (parenting practices, family cohesion and conflict, and family attitudes and beliefs), significant losses, community functioning, quality of life and life events, and future orientation. The CFA module contains two datasets: da34931-0009 (732 variables, 1742 observations) and da34931-0010 (43 variables, 8970 observations).
- The Children's Global Assessment Scale (GAS) module summarizes the interviewer's impression of the lowest level of the participant's functioning at home, in school and/or work, and in other social environments. This dataset (da34931-0011) has 4 variables and 1737 observations.
- The Diagnostic Interview Schedule (DIS), Version IV is a structured interview that assesses psychiatric disorders based on DSM-IV criteria. The dataset referencing the interview questionnaire (da34931-0013) contains 734 variables and 1741 observations. These variables include demographics, alcohol withdrawal, dependence, and abuse; amphetamine withdrawal, dependence, and abuse; Antisocial Personality Disorder, and Conduct Disorder. The diagnostic dataset (da34931-0012) contains 665 variables and 1741 observations. These variables were generated by scoring algorithms using items from the interview questionnaire.
- The Diagnostic Interview Schedule for Children (DISC), Version 2.3 is a structured interview, of children, that assesses psychiatric disorders based on DSM-IV criteria. The interview questionnaire (da34931-0015) contains information regarding: demographics, anxiety disorders, Post-Traumatic Stress Disorder, Major Depression/Dysthymic Disorder, Mania/Hypomania, Schizophrenia, Attention-Deficit/Hyper Activity Disorder, Oppositional Defiant Disorder, Conduct Disorder, and Antisocial Personality Disorder. This dataset includes 1517 variables and 1747 observations. An additional dataset contains variables regarding the diagnoses for psychiatric disorders that were generated by scoring algorithms using items from the interview questionnaire (da34931-0014) with 587 variables and 1747 observations.
- The Risky Behavior Assessment Profile (RBAP) assesses drug use, HIV/AIDs risk, and criminal activity. Items were drawn from Washington, DC, Metropolitan Area Drug Study of Juveniles, National Institute of Drug Abuse's (NIDA) Risk Behavior Assessment, the Adolescent Health Survey from the NIDA Study of Street Youth at Risk for AIDS, and the Denver Youth Survey. Modules include: drug use history and recent drug use (da34931-0017: 104 variables, 4921 observations); injection drug use (da34931-0019: 71 variables, 12 observations); sexual risk behavior (da34931-0021: 150 variables, 1895 observations); participation in AIDS intervention programming (da34931-0020: 61 variables, 3217 observations); and AIDS knowledge, violent behavior, gang activity, and attitudes and peer behavior (da34931-0016: 1046 variables, 1740 observations). There is also a separate dataset containing coded open-ended responses (da34931-0018: 20 variables, 1711 observations).
- The incarceration data (INCARCERATION) (da34931-0022: 10 variables, 1751 observations) comes from a combination of correctional records and self-report, and includes information on the number of days incarcerated prior to the interview.
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).
