About the ABCD Data Repository
The ABCD Data Repository is a part of the National Institute of Mental Health Data Archive (NDA). The NDA infrastructure was established initially to support the National Database for Autism Research (NDAR), but has grown into an informatics platform that facilitates data sharing across all of mental health and other research communities. Data are released and made available through the ABCD Data Repository on two schedules. Fast Track data include only raw imaging data, and are released on an ongoing basis throughout the year. Processed imaging data and assessments are made available annually, starting in February 2018, in a curated release.
The ABCD Data Repository was established to store and share data generated by investigators as part of the ABCD Study, a collaborative effort sponsored by the National Institute on Drug Abuse (NIDA), as well as the National Institute on Alcohol Abuse and Alcoholism (NIAAA), the National Cancer Institute (NCI), the National Institute of Mental Health (NIMH), the Eunice Kennedy Shriver National Institute of Child Health and Development (NICHD), the National Institute on Minority Health and Health Disparities (NIMHD), the National Institute of Neurological Disorders and Stroke (NINDS), the NIH Office of Behavioral Social Sciences Research, the NIH Office of Research on Women's Health, the National Heart, Lung, and Blood Institute (NHLBI), and the Centers of Disease Control and Prevention - Division of Adolescent and School Health.
The NIH seeks to encourage the use of these resources to achieve rapid scientific progress. In order to take full advantage of such resources and maximize their research value, it is important that data be made available, on appropriate terms and conditions, to the largest possible number of qualified investigators in a timely manner.
