McCrady, Johnson, & Pandina, 1999; Neumann, Wampler, Taylor, Blonigen, & Iacono, 2011; Odgers et al., 2008; Petersen et al., in press; Pitkanen et al., 2008), we believe it is appropriate to conceptualize the measures as global indices of parental externalizing behavior. Lastly, paternal antisocial behavior and alcohol problems data were not available for all participants, which may have resulted in an underestimation of these indices since these behaviors are more prevalent in males than in females. The impact of this underestimation on the association between antisocial behavior and alcohol problems in the parental generation, life events, and adolescent externalizing is unknown.
