The Center on Antisocial Drug Dependence (CADD) has collected data for more than ten years on clinical probands, their siblings and relatives, as well as community-based genetically-informative samples, e.g., twins and adoptees. Key instruments include substance use and dependence interviews from the Composite International Diagnostic Interview - Substance Abuse Module (CIDI-SAM), and selected psychiatric modules from the Diagnostic Interview Schedule for Children (DISC). The purpose of this web page is to allow access to deidentified data files to CADD researchers via the web.
