FAQs

Access to ABCD Study data is managed through the NIH Brain Development Cohorts Data Use Certification (DUC) process. To login to DEAP you need to have an approved DUC. If you have applied for a DUC and been approved you may still need to complete your NBDC Responsible Data and Biospecimen Use Training (see last tab at the NBDC DUC website for more details).

Reminder: Users can use the DEAP data dictionary explorer without an active DUC. Creating datasets & subsequent actions (download, analysis, etc) are limited to users with active DUCs.
