ABCD study data

The ABCD study ( neuroimaging data (Y1: 11,874 9-10 yo children) are being made available to researchers at Washington University. Please see the attached NDA (National Data Archive) required access procedure for instruction on how to request access.

Access to the locally hosted ABCD data are only permitted for individuals who have followed the request procedures and received confirmation that permissions have been granted by the NDA on the Data Use Certification (DUC) with Nico Dosenbach. This must be completed prior to accessing ABCD data on the WashU ABCD server. It is the responsibility of each individual accessing ABCD data to keep the contractual terms of the DUC as granted by the NDA, including not sharing the original data with anyone. To ensure that only individuals with permissions have the ability to view this data, data files must not be copied by any person to any other server location.

Funding for ABCD data storage, preprocessing, and data management at Washington University has been provided by the McDonnell Center for Systems Neuroscience, the Neuroimaging Laboratory (NIL), the Institute of Clinical and Translational Sciences (ICTS) and the Intellectual and Developmental Disabilities Research Center (IDDRC) in collaboration with the Dosenbach laboratory.  The original and processed MRI data are provided to the Washington University Neuroimaging Community in an effort to bypass duplicating storage and processing costs across many research groups, and thus fast-track applied research and data utilization. The ABCD study itself is funded by the NIH and headed by the Collaborative Research on Addiction at NIH (CRAN) in collaboration with several NIH Institutes and Centers. For a general overview of the ABCD study and data types, please see the attached ABCD study dataset infosheet.
