Substance Use module for adolescents (module #510301), the Monitoring the Future (MTF) Study (http://www.monitoringthefuture.org/) (Institute for Social Research and U.o.M. Monitoring the Future, 2010), the Population Assessment of Tobacco and Health (PATH) Study (https://pathstudyinfo.nih.gov/UI/HomeMobile.aspx) (Hyland et al., 2016), and the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA) Study (http://ncanda.org/) (Brown et al., 2015) (see Table 1 for instrument overlap identification). Further, great care and consideration was put into organizing a gating structure to avoid exposing non- or low-using children to novel substances (see “heard of” section below and Table 1 for gating details). After developing the draft protocol, the workgroup received and integrated feedback from the NIH advisors and the ABCD Study Coordinating Center, and piloted the protocol at multiple sites with 9–10 year olds to ensure youth comprehension, confirm data quality and timing. Consistent with the goals of the ABCD Study, curated data and detailed data dictionaries, including all the substance use measures, will be released yearly to the NIMH Data Archive (NDA; https://data-archive.nimh.nih.gov/) (for further data sharing details, see https://abcdstudy.org/scientists_data_sharing.html and the ABCD Study overview paper included in this special issue).Table 1ABCD Substance Use Module Measures Overview (by Youth- and Parent-Administered Measures).Table 1Youth MeasuresConstructGatingDrugs CoveredLifetime and
