Although the young adult follow up is not completed, it was instructive to determine the rates of illness among a group of 118 offspring who had their most recent follow up visit some time between the ages of 18–22 years. Obtaining estimates of diagnostic prevalence for those currently transitioning from adolescence to young adulthood is of considerable interest because it often represents a time when youngsters leave the parental home for college or to live on their own away from parental supervision. Using this strategy we find that high risk offspring have significantly elevated rates of Alcohol Abuse/ Alcohol Dependence, Drug Abuse/Drug Dependence, Anxiety Disorders and MDD in comparison to low risk offspring (Table 6).
