Abstract

The ABCD Curated Data Release 5.1 addresses data quality issues discovered after the Release 5.0. For a detailed description of these changes and all of the measures included in this release, visit the 5.1 release notes available at https://docs.abcdstudy.org/latest/documentation/release_notes/ . Release 5.1 includes high-quality baseline and longitudinal data from ~11,880 research participants, including minimally processed brain image volumes and tabulated structural MRI, diffusion MRI, resting-state fMRI, and task fMRI results, as well as all non-imaging assessment data from the genetics, mental health, physical health, neurocognition, substance use, novel technology, culture & environment, gender identity and sexual health workgroups, and linked external data. Data from associated substudies are also included (Social Development, Endocannabinoids, Hurricane Irma). Raw data are available for the neurocognitive and task fMRI studies, and selected data from the physical health and substance use domains. For neuroimaging assessments, this release contains all baseline and 2-year follow-up data, and about half of the 4-year follow-up data. For non-imaging assessments, this release contains complete data from the baseline, 6-month, 1-year, 18-month, 2-year, 30-month, and 3-year follow-up visits, and about half of the cohort for the 4-year and 42-month follow-up visits. The original data have been taken down from the NIMH Data Archive (NDA) and uploaded on to the NIH Brain Development Cohorts (NBDC) Data Hub
