for the effects of parental alcohol use and misuse (ie: the parental combined alcohol problem index), elder sibling alcohol use and misuse (ie: the elder sibling combined alcohol problem index), and peer deviance, we fit a successive series of incrementing models including the change in the effect of each potential environmental moderator over time, the interaction of each with ALDH2 genotype, and the change in the interaction of each with ALDH2 genotype over time.
