ABCD Annual Releases
ABCD Annual Release Data are static, curated data sets that include 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 physical & mental health, neurocognition, substance use, biospecimens and culture & environment domains. Curated data are QA'd, then defined by an NDA Study and assigned a Digital Object Identifier (DOI). Researchers intending to use Annual Release data should take note of the appropriate Acknowledgement language to include in any public disclosure of results.
All personally identifiable information is removed from the data to ensure participant confidentiality and anonymity. Data can be accessed via the NDA by researchers who obtain a free NIMH Data Archive account. If you don't have an account already, you can create one here.
