The ABCD Consortium is made up of a Coordinating Center (CC), Data Analysis, Informatics & Resource Center (DAIRC), and 21 research sites across the country. The ABCD CC, DAIC, and Consortium Workgroups have established standardized and harmonized assessments of neurocognition, physical and mental health, social and emotional functions, and culture and environment. They also have established multimodal structural and functional brain imaging and bioassays. Brain imaging and biospecimen collection for genetic and epigenetic analyses will be done every other year, and the remaining assessments will be conducted semi-annually or annually.
