The Denver Youth Survey (DYS) is part of the larger "Program of Research on the Causes and Correlates of Delinquency" initiated by the Office of Juvenile Justice and Delinquency Prevention in 1986. It is a longitudinal study of problem and successful behavior over the life course that focuses on delinquency, drug use, victimization, and mental health. DYS variables also address family demographics, neighborhood characteristics, parenting, and involvement in social roles.
The DYS is based on a probability sample of households in "high-risk" neighborhoods of Denver, Colorado. These neighborhoods were selected on the basis of their social ecology in terms of population and housing characteristics. Only socially disorganized neighborhoods with high (top one-third) official crime rates were included. The survey respondents include 1,528 children and youth who were 7, 9, 11, 13, or 15 years old in 1987, and one of their parents, who lived in one of the more than 20,000 randomly selected households.
The survey respondents include 807 boys and 721 girls and include White (10%), Latino (45%), and African American (33%) youth, as well as 12% from other racial/ethnic backgrounds. The child and youth respondents, along with one caretaker, were interviewed annually from 1988 until 1992 (waves 1-5), annually from 1995 until 1999 (waves 6-10), and in 2003 (wave 11). The study covers an age range of 7 through 26.

HideFunding for the Denver Youth Survey has been provided since 1986 by the Office of Juvenile Justice and Delinquency Prevention (OJJDP) with supplemental funding from the National Institute on Drug Abuse (NIDA), the National Institute of Justice (NIJ), the German-American Academic Council (GAAC) and the John D. and Catherine T. MacArthur Foundation through their program on Successful Adolescence. Funding for data collection in waves 6 through 10 (1995-1999) of the DYS was primarily provided by the National Institute on Drug Abuse (NIDA) with supplemental funding from OJJDP. OJJDP provided funding for data collection in wave 11 (2003).
The datasets contain some variables that were masked by the DYS research team due to confidentiality concerns, so not all variables described in the data documentation are available for data analysis.
The Denver Youth Survey (DYS) examines the causes, correlates, and consequences of delinquency, drug use, and other problem behaviors. DYS is a longitudinal study of problem and successful behavior over the life course that focuses on delinquency, drug use, victimization, and mental health. The study focuses on children, youth, young adults, and one of their parents in "high risk" neighborhoods of Denver, Colorado, with neighborhoods selected on the basis of their elevated crime rates and social ecology (in terms of population and housing characteristics).
The design of the DYS included the selection of respondents from socially disorganized neighborhoods of Denver, Colorado. Socially disorganized neighborhoods were identified by a formal social area analysis. In addition, respondents were selected from socially disorganized areas that had higher than average crime rates.
For waves 6-11, interviews were conducted on laptop computers using computer-assisted interviewing software. For administering the self-report delinquency and drug use (SRD) measure, respondents were first asked about frequency of involvement across all SRD items. More detailed follow-up questions were then asked only for items that had a positive response.
All interviews were conducted in private settings, usually in the respondent's home. The vast majority of interviews were conducted in a face-to-face format, although respondents who moved some distance from the research site (nationally or internationally) were interviewed in later waves by telephone under strict privacy rules. All interviews (child, youth, young adult, and parent) were conducted after obtaining informed consent/assent from the respondent and from a parent of all respondents under the age of 18.
A total of 45,694 households were identified in the enumeration process. In the first sampling, 18,804 households were selected. The second or over-sampling of the "traditional disorganized" area included an additional sample of 1,473 from the 12,204 enumerated households in this stratum.
Sampled households were screened for the presence of eligible children and youth (those aged 7, 9, 11, 13, or 15 in 1987) by completing a household listing ("family chart") of all persons residing in a selected household and obtaining their birth dates. This screening information was obtained from an adult residing in the household. Households containing an eligible child/youth respondent were included in the sample, and interviews with all eligible children and youths, and one of their parents (principal caretaker) were attempted.
The screening process resulted in listings for 20,331 households or "listing lines" and in households in which two or more families were living, a separate family chart was obtained for each family. For the purpose of the study, each additional dwelling unit and each additional family in multiple family households resulted in an additional "listing line," so that all individual families that included an eligible child would each be interviewed as a separate family. Because of this, there are more households listed as being screened than the size of the original household sample. Also, during the screening effort, it was discovered that some structures identified as dwelling units during the enumeration process, were not in fact dwelling units. When such structures were selected as part of the household sample, they were considered to be "blank draws," to preserve the original sampling fraction and not affect the probability of selection of other households. The overall successful screening completion rate was approximately 92 percent.
Of 1,360 households that contained eligible youth, interviews were completed in 1,145 households. The remaining 215 households were "family refusals," where in most cases parents refused to participate for themselves and for their children. In a very few cases, the parents provided permission, but all of the children in the household/family refused to participate. Similar outcomes hold for families, which includes counts for families living in multiple family households. In 21 households, a child or youth interview was completed but an interview with the parent/caregiver for that household was not completed.
A total of 1,808 eligible youth resided in the successfully screened sampled households, of whom 1,528 completed an interview in the first year of the study, for a completion rate of 85 percent. A total of 1,132 parents/principal caretakers of these youth also completed 1,496 interviews about their participating children, for a completion rate among parents of participating youth of 98 percent.
Youth and young adults (and one of their parents) who were 7, 9, 11, 13, or 15 years old in 1987 and living in socially disorganized neighborhoods with high official crime rates in Denver, Colorado.
The DYS is organized by respondent and divided into two separate datasets, both of which contain an identifying variable (CASEID) for all 1,528 respondents included in the original sample. The youth/young adult data include all respondents across waves 6-11 (n=1,528; 26,635 variables). Individual waves can be separated from the combined data files with variable and case counts as follows:
Only two of the five birth cohorts (age 7 and 9 in 1987) were still within the age range of the study (ages 7-26) in 2003, when Wave 11 interviews were conducted.
A second data file includes all parent respondents across waves 6-10 (n=1,528; 6,142 variables), with variable and case counts for individual waves indicated below:
The selection of variables was guided by the problem behaviors and by the rich mix of variables provided by a theoretical model guiding the project with a focus on biological history, neighborhood social disorganization and effect, conventional and deviant socialization and bonding, personality and mental health, peer influences, secondary (external) controls and rational choice. Topics covered in the data include:

Hide2016-12-30
2016-12-30 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:
Weights were derived from the inverse of the probability of household selection within each stratum, normed to provide an approximation to the original total sample size. The normed weights were used so that the general sample size of the study would be maintained and the power of statistical tests would more appropriately reflect the actual sample size of the study.
