These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.

This collection features secondary analyses of restricted-use data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a nationally representative longitudinal study of a sample of U.S. adolescents who were in grades 7-12 in the 1994-95 school year, who were interviewed at three key developmental junctures from adolescence to young adulthood. Self-reported data were used for both maltreatment (measured at the latter two time points) and delinquent or criminal behaviors (measured at all three time points). Linear mixed-effects analyses were used to model growth curves of the frequency of violent and non-violent offending, from ages 13 to 30. Next, maltreatment frequency was tested as a predictor, and then potential protective factors (at peer, family, school, and neighborhood levels) were tested as moderators. Sex, race/ethnicity, and sexual orientation were also tested as moderators of delinquent or criminal offense frequency, and as moderators of protective effects.

The study collection includes 1 Stata (.do) syntax file (AddHealthOJJDPAnalysis_StataSyntax.do) that was used by the researcher in secondary analyses of restricted-use data. The restricted archival data from the Add Health survey series are not included as part of this release.

The study includes data collected with the purpose of creating an integrated dataset that would allow researchers to address significant, policy-relevant gaps in the literature--those that are best answered with cross-jurisdictional data representing a wide array of economic and social factors. The research addressed five research questions:

1. What is the impact of gentrification and suburban diversification on crime within and across jurisdictional boundaries?
2. How does crime cluster along and around transportation networks and hubs in relation to other characteristics of the social and physical environment?
3. What is the distribution of criminal justice-supervised populations in relation to services they must access to fulfill their conditions of supervision?
4. What are the relationships among offenders, victims, and crimes across jurisdictional boundaries?
5. What is the increased predictive power of simulation models that employ cross-jurisdictional data?

This two-phase study examined factors influencing decisions that lead from a school-based incident to exclusionary discipline, an arrest, and a referral to the juvenile court. The research team hypothesized that multiple external factors such as race identity, socioeconomic status, and others would negatively impact the decision-maker, and generate harsher punishments for those who are in these vulnerable groups. Phase 1 involved interviewing groups of key stakeholders including school administrators, district administrators, discipline coordinators, juvenile court judges and other staff, law enforcement officers, Positive Behavior Intervention Support (PBIS) coordinators, and child welfare agencies to understand their approaches to behavior management. Phase 2 involved secondary analysis of data from local school districts and the juvenile court with jurisdiction in two counties.

Across the country, child welfare and juvenile justice systems now recognize that youth involved in both systems (i.e., dual system youth) are a vulnerable population who go unrecognized because of challenges in information-sharing and cross-system collaboration. These challenges currently prevent the development of accurate estimations of the number of dual system youth nationally and limit understanding of best practices used by jurisdictions implementing integrated systems models. OJJDP funded this secondary analysis study to address this gap in knowledge.

All data used in the Dual System Youth Design Study were owned or accessed by various partners. No primary data collection occurred in the study. In addition, most of the data accessed by the study partners was confidential, de-identified data that required memorandums of agreement and/or court orders to access and use. Some sites have ongoing or standing agreements with the public agencies who own the data which allow access and use for specific projects. Because, most frequently, the data are owned by the public service agencies and include sensitive information the data are not available to be publicly archived. Instead, here a descriptive overview is provided of the data used and accessed by each study partner as well as contact information of a person at each site that will be able to share syntax and/or coding parameters for those who are considering to replicate the findings or methods.

Researchers interested in inquiring the data and syntax used in this project should refer to the study partners section of the downloadable study documentation. Data provider agency names along with the specific study data that were requested are listed in the documentation.

This study consists of a secondary analysis of data from the Educational Longitudinal Study of 2002 (ELS) to investigate associations between immigration, misbehavior, victimization, disorder, and educational failure (i.e., dropping out). Six research questions that were addressed in this study include: do school social bonds vary across immigration generations? Second, is student violence (i.e., misbehavior and victimization) explained by school social bonds across generations? Third, are student violence and school disorder related to the children immigrants' likelihood of dropping out? Fourth, are strong school social bonds mitigating the likelihood of dropping out for the children of immigrants? Fifth, are immigrant school enclaves associated with increased school social bonds among adolescents, decreased student violence and school disorder, and lower levels of dropping out? Sixth, does the intersection of race, ethnicity, and gender moderate the relationship between student violence and school social bonds for the children of immigrants?
