数据描述

The ABCD Data Repository in the NIMH Data Archive houses data from the Adolescent Brain Cognitive Development (ABCD) Study, a prospective longitudinal cohort following nearly 12,000 diverse youth recruited at ages 9–10 across 21 U.S. research sites for 10 years. The dataset contains curated and tabulated behavioral, social, emotional, cognitive, mental health, substance use, gender identity/sexual health, physical health, biospecimen, and environmental measures, along with brain imaging data including structural MRI, task fMRI, and resting-state fMRI, plus minimally processed and FastTrack MRI and raw behavioral data. Linked external databases add contextual indicators such as local environment, poverty, pollution, school, and policy to support research on adolescent development.
