Workgroups

The ABCD Consortium has established workgroups to guide the development, refinement, and dissemination of the study design, protocols, informatics and software to facilitate the implementation of the study. Comprised of ABCD investigators and collaborators with domain expertise, each workgroup meets regularly to assess and address the relevant needs of the consortium in light of scientific or technological advancements.

Assessment Workgroups

Reviews the current state-of-the-science to recommend appropriate non-imaging measures for inclusion in the protocol considering developmental appropriateness, psychometrics, anticipated stability and change over the study period, harmonization with the larger research literature, articulation with the entire measurement battery, and subject burden. When indicated, the assessment groups make recommendations for modifications to the assessments that might be indicated by new scientific findings, improved technologies, or demonstrated limitations of existing protocols (e.g., decreasing sensitivity to maturing cohort).

Health and Mental Health
Focuses on identifying a core set of measures to obtain information from parents and children on mental health relevant experiences, behaviors, and attitudes, physical health relevant attributes and behaviors, and environmental exposures important for both physical and mental health.

NeuroCognition
Neurocognitive measures collectively assess participants' levels of crystallized and fluid reasoning, reading ability, working memory, behavioral inhibition, verbal learning and memory, sequencing skills, processing speed, attention, and visuospatial reasoning. Measures were selected to maximize data quality across the ten year longitudinal assessment, and to be sensitive to small changes in cognitive efficiency as children move from adolescence into adulthood.

Substance Use
Focuses on assessment of lifetime and recent quantity/frequency and patterns of use of all major drug categories (alcohol, nicotine, marijuana, caffeine, stimulants, ecstasy, depressants/sedatives, opiates, hallucinogens, steroids, and inhalants). Important predictors of substance use are also captured, including peer use, perceived harm of use, disapproval of use, availability of substances and intention to use. Measures were selected to be developmentally-appropriate and gated to: 1) avoid exposing non- or low-using youth to substance use questions; and 2) assess motives, expectancies, symptoms, craving and withdrawal in youth reporting use.

Culture & Environment
Selects measures of socio-cultural and environmental factors that may confer risk or protection to the development of health or mental health problems in youth. Whenever possible, measures are chosen to be brief, appropriate for administration throughout adolescence, and valid across cultures. The domains that are assessed span individual, family, school, and neighborhood factors and include prosocial behaviors, problem solving, independence/self-reliance, acculturation, biculturalism, parental monitoring, parental warmth, family conflict, familism, school environment, and neighborhood safety.

Biospecimen and Developmental Biomarkers
Recommends collection of several biological samples to provide information on genetics, pubertal and other hormones, exposures to various compounds, and other health measures. Sampling techniques, including saliva samples and blood testing, were selected to minimize participant discomfort and maximize data quality across the ten year longitudinal assessment, and to help validate self-report information.

Mobile Technologies & Passive Data Collection
Focuses on methods to collect key information with minimal burden to participants, often using technology. One pilot project will use wearable sensors (e.g., Fitbits) to measure activity, sleep, and other health indicators in youth. Social media use, including mobile applications for data collection, may also be explored in the future.

Design & BioStatistics

Ensures that all aspects of the study design, including sampling methods, twin cohort (and other forms of relatedness), and risk enrichment strategy are monitored in an integrated way, and that the biostatistical approaches used to address the study aims are optimal for, and take full advantage of, all aspects of the study design. This group includes a subcommittee focused on designing standardized recruitment and retention strategies consistent with the sampling methods and design, and aimed at achieving the desired cohort demographics.

Outreach & Dissemination

Develops and implements a strategy to effectively engage ABCD stakeholders, promote awareness about the study and its benefits, and encourage participation in the study by developing outreach materials (e.g., website, brochures, recruitment letters, videos), identifying vehicles and influencers to amplify our message to further raise awareness, and working with the Coordinating Center to monitor site outreach to identify gaps and propose solutions when needed. The group also coordinates the dissemination of study findings to stakeholders and constituents as they are available.
