demonstrated that an underlying genetic predisposition toward behavioral disinhibition in childhood can manifest as alcohol dependence in adulthood (Dick et al., 2006). However, questions continue to be raised in the literature about the extent to which family density of alcohol problems influences behavioral disinhibition in children. Capone and Wood (2008) found that the association between family density and young adult alcohol problems was mediated by impulsivity and the willingness to take risks. However, these traits were self-reported in adulthood. Thus, to determine whether familial alcoholism operates through one or more domains of behavioral undercontrol in children, more work is needed with multiple reporter data that considers the possible disaggregated structure of the larger behavioral construct.
