Abstract

The ABCD Curated Data Release 6.0 includes high-quality baseline data (9-10 years of age) from 11,868 research participants and longitudinal data through the 6-year follow up (15-16 years of age), including raw and derivative MRI data (minimally processed brain image volumes and Freesurfer data), tabulated structural MRI, diffusion MRI, resting-state fMRI, and task fMRI results, as well as non-imaging assessment data from the genetics, mental health, physical health, neurocognition, substance use, novel technology, and culture & environment domains, and linked external data. Item-level data are available for the neurocognitive and task fMRI studies, as well as selected file-based data from the genetics, novel technology, and substance use domains. For neuroimaging assessments, this release contains all baseline, 2-year, 4-year, and about half of the 6-year follow-up data. For non-imaging assessments, this release contains complete data from the baseline through the 4-year follow-up visits, most of the data from the 5-year follow-up visit, and about half of the data from the 6-year follow-up visit. Data from associated substudies are also included (Social Development, Endocannabinoids, Hurricane Irma, COVID-19, MR Spectroscopy).
