ABCD 7.0 Release Announcement

We are pleased to announce the 7th annual release of data from the Adolescent Brain Cognitive DevelopmentSM (ABCD) Study, as well as the Data Exploration & Analysis Portal (DEAP), a graphical user interface for creating, visualizing, and analyzing NBDC datasets in place.

‍

The ABCD Study® is the largest longitudinal study of brain development and child health in the United States. The ABCD 7.0 Data Release includes cumulative data from the full participant cohort through the 5-year follow-up visit and nearly the entire cohort at the 6- and 7-year follow-up visits. ​​​​The ABCD 7.0 data release also contains whole-genome sequencing data for approximately 80% of the cohort, longitudinal linked external data, as well as data from associated substudies, including Social Development, COVID-19, and the newly added Baby Teeth, RECOVER, and Structured Interview for Psychosis-Risk Syndromes. For detailed information about the ABCD 7.0 Data Release, please visit the ABCD documentation page.

NBDC Data Hub

ABCD (and HEALthy Brain and Child Development, or  HBCD) Study data are available through the NIH Brain Development Cohorts (NBDC) Data Hub, a secure data management and analysis platform offering:

  • Scalable integration of large, multimodal datasets, including neuroimaging, EEG, and genomics data
  • Customized query tools and data ontologies to identify variables of interest
  • Compute-in-place Sandbox with standard tools (RStudio, Jupyter Notebooks, Linux desktop)
Controlled-access

To access the data, researchers must apply for a Data Use Certification (DUC), complete the required Responsible Data and Biospecimen Use Training, and attest to compliance with NIST SP 800-171 security standards (or equivalent ISO/IEC 27001/27002 standards) per NIH requirements. The NBDC Data Hub will soon introduce a non-NIST data access workflow for investigators whose institutions do not plan to implement NIST-compliant computing environments. Further details will be available soon.
