the current results are complementary to the concept of ‘heterotypic continuity ’: rather than a single latent liability manifesting differently across development, we observe here a consistent phenotype (alcohol consumption) that is influenced by distinct latent liabilities during different developmental periods. The similarities between the current results and those aimed at characterizing risk of antisocial behavior could have a substantive foundation: a broad literature exists examining relationships between antisocial behavior and alcohol problems, including research suggesting that the risk to children of alcoholics developing their own problems could proceed along an antisocial pathway, with executive functioning deficits representing an alternative pathway (Nigg et al. 2004, 2006).
