Similar to many other studies showing strong associations between antisocial behaviors and alcoholism within individuals and within families (e.g. Zucker, 2006), we found the expected association between familial alcohol problem density and conduct problems (CP). Although the magnitude of association was small (8% of variance in the less effectively parented subgroup), this finding provides further evidence of a deviance-proneness pathway for the transmission of alcoholism in families (Sher, 1991) by extending the model to include density of alcohol problems in the family. Thus, greater familial loading may be tapping into the Type II or Type B variant of alcoholism that includes antisocial tendencies and that is more severe and chronic. The association between density and the latent factor of behavioral disinhibition, although lower in magnitude than the association between density and conduct problems, suggests that as a group these temperament traits may also play a role in alcohol vulnerability transmitted within families. These traits are visible and measureable at an early age, are highly heritable (Krueger et al., 2002; Price et al., 2001; Slutske et al., 1997), and have previously
