been reported to be a better predictor of SUD outcome than having a family history of psychopathology, having divorced parents, or family income (Schuckit et al 2008). Two studies have reported that presence of either Oppositional Defiant Disorder or Conduct Disorder in childhood increased the likelihood of developing a SUD in young adulthood though these studies did not assess the possible conjoint effects of familial risk for AD or other SUD (Nock et al., 2006, 2007). The present results based on offspring from maternal alcohol dependent families finds ADHD and Conduct Disorder in childhood significantly decreased survival time for SUD.
