A structural model on parent/adult-child alcohol use patterns was examined. Three analytical blocks were specified: adult-children's alcohol use onset by types of alcoholic beverage, their current use of these alcoholic beverages, and parents' drinking patterns. The model was examined with data collected from drunken driving offenders in California and Maryland treatment programs. The findings indicate that parent/child alcohol use transmission is more gender specific than race specific; fathers' drinking tends to affect sons' drinking and mothers' drinking tends to affect daughters' drinking. Beer use onset is the earliest and more effective in influencing future alcohol use than the onset of wine or liquor.
