Exclusion criteria were verified by a demographic and health interview questionnaire administered to the participant as well as a parent, by the Wechsler Abbreviated Scale of Intelligence (WASI: (39)), and by structured diagnostic interviews (the Kiddie Schedule for Affective Disorders: (40)) administered to the participant as well as (for those under age 18) a parent. Family history interviews verified that participants did not have first-degree relatives with substance use disorders.
