Better Together.

The Adolescent Brain Cognitive DevelopmentSM (ABCD) Study is the largest long-term study of brain development and adolescent health in the United States. Our collaborative research group collects and makes available data to understand and promote the health, well-being, and success of children and adolescents.

The ABCD consortium aspires to be anti-racist, just, inclusive, equitable, and diverse. To do so, we exercise humility, acknowledge limits of our knowledge, and strive to improve our understanding by listening to diverse perspectives and responding thoughtfully. We continue to educate ourselves about the ways discrimination and systemic oppression have shaped the scientific community, and collaborate with individuals and groups who have expertise in anti-racism, equity, justice, diversity, and inclusion.

It is our deepest aspiration that ABCD study data will be utilized responsibly by scientists and key stakeholders around the globe and that scientific findings inform the development of just and equitable policies to elevate the quality of life of all youth. (click image below to learn more)

Justice, Equity, Diversity and Inclusion (JEDI)

To support ABCD’s work towards these values, consortium team members have assembled to form multiple working groups focused on justice, equity, diversity, and inclusion (JEDI). To learn more about the overarching mission and goals of the consortium-wide JEDI efforts, click the following links to learn about the Advisory Council and Workgroups.

The JEDI Workgroups address JEDI-related issues regarding study measures and protocols, staff and participants, and the responsible use of ABCD data. As creators and users of the ABCD dataset, we are responsible for ensuring the data are modeled, analyzed, interpreted, and communicated in ways that do not perpetuate harm to individuals or populations. The JEDI Workgroups are actively involved in developing informative Wiki and release notes highlighting important JEDI-related issues like measure changes and the implications for data analysis.
