ABCD Social Development (ABCD-SD)

The ABCD Study is the largest longitudinal study of brain development and child health in the US, following approximately 10,000 children (ages 9-10) across 21 sites into their early adulthood years. The ABCD Study seeks to explore the standards of normal brain development across a young person’s life trajectory, as well as numerous facets of adolescent brain, cognitive, social, emotional, and physical development. In particular, there is limited understanding regarding the long term impact of substance abuse on the developing brain and later healthy outcomes. Delinquency and victimization represent two such serious adverse outcomes that are especially relevant for the adolescent developing brain that is particularly vulnerable and characterized by dramatic changes in structure and function. While it has been shown that substance use is strongly linked to these negative outcomes, the directions and longitudinal trajectory of these associations, the unique and additive effects of different substances, and underlying neurobiological mechanisms are unclear. The sub-study will address key questions on the interactions between substance use, brain development, delinquency, and victimization.

This proposal outlines the first 18 months of a prospective delinquency and victimization sub-study (the ABCD-Prosocial Development Study; ABCD-SD). The study is an add-on to the main Adolescent Brain Cognitive Development study (ABCD). The aim of the study is to shed light on the associations between substance use exposure, delinquency and victimization, and the developing brain. The ABCD-SD will collect data from 5 of the 20 sites of the main ABCD study, involving a projected total of nearly 3000 boys and girls, who will be on average 11-12 years-old at Time 1 of the main ABCD-SD Study. Interviews with juveniles and their parents will be conducted in clinical visits. Measurements are self-reported delinquency, personality disposition, victimization, sociopsychological, family, peer and neighborhood factors (risk and protective factors). The first 6 months of the project is a preparatory phase; finalizing the assessment protocol, setting up collaboration systems with participating sites, NIJ, and the ABCD main study. Months 12-18 consist of data collection, quality control, reliability and validity checks, implementation fidelity follow up, and cleaning of data. In addition, preliminary analyses including the first wave of data will be conducted together with initial data from the main ABCD study.

This application proposes a supplement to support the fifth year of the ABCD-Social Development Study (ABCD-SD). ABCD-SD is a prospective study on adolescent delinquency and victimization. ABCD-SD is a sub study of the Adolescent Behavior and Cognition Development Study (ABCD), utilizing the extensive ABCD data on cognitive and brain development while adding measures on delinquency and victimization risks and outcomes for participants at 5 of the 21 ABCD sites (n=2,426). The aim of ABCD-SD is to advance understanding of the influences of deficits and maturational delays in cognitive and brain development, substance use exposure, and pre-exposure phenotypes on delinquency trajectories and responses to victimization. This knowledge is crucial to informing policymakers and prevention science to decrease the number of juveniles in the juvenile or criminal justice system. ABCD-SD is collecting data from 5 ABCD sites, involving a total of 2426 participants, who were on average 13.43 years old at their first ABCD-SD assessment visit. Interviews and questionnaires will be collected with participants and their parents at annual visits. The ABCD-SD assessments measures a wide array of risks, protective factors and outcomes, including self-reported delinquency, victimization, personality dispositions, sociopsychological characteristics, family relationships, peer delinquency and neighborhood factors. The activities of Year 5 will include participant tracking, follow-up assessments (Wave 2, 3, & 4), quality control, reliability and validity checks, implementation fidelity, and cleaning of data. In Year 5, baseline data will be available for full analyses and will be conducted together with integrated ABCD data. We will prepare a report to NIJ describing the study progress and one or more scientific publications based on these initial data.

This application proposes a supplement to support the sixth year of the ABCD-Social Development Study (ABCD-SD). ABCD-SD is a prospective study on adolescent delinquency and victimization.  ABCD-SD is a sub study of the Adolescent Behavior and Cognition Development Study (ABCD), utilizing the extensive ABCD data on cognitive and brain development while adding measures on delinquency and victimization risks and outcomes for participants at 5 of the 21 ABCD sites (n=2,426). The aim of ABCD-SD is to advance understanding of the influences of variations of and maturational delays in cognitive and brain development, substance use exposure, and pre-exposure phenotypes on delinquency trajectories and responses to victimization. This knowledge is crucial to informing policymakers and prevention science to decrease the number of juveniles in the juvenile or criminal justice system. ABCD-SD is collecting data from 5 ABCD sites, involving a total of 2426 participants, who were on average 11.7 years old at their first ABCD-SD assessment visit. Interviews and questionnaires will be collected with participants and their parents at annual visits. The ABCD-SD assessments measures a wide array of risks, protective factors and outcomes, including self-reported delinquency, victimization, personality dispositions, sociopsychological characteristics, family relationships, peer delinquency and neighborhood factors. The activities of Year 6 will include participant recruitment and tracking, follow-up assessments (Wave 3, 4, & 5), quality control, reliability and validity checks, implementation fidelity, and cleaning of data. In Year 6, baseline and follow up data will be available for analyses and will be conducted together with integrated ABCD data. We will prepare a report to NIJ describing the study progress and one or more scientific publications based on these initial data. NCA/NCF
