There has been limited investigation of mothers’ drinking patterns and their experience of domestic abuse while parenting young children, especially in the context of co-resident fathers’ drinking. Using data representative of the 2001 U.S. birth cohort, the authors conducted longitudinal latent class analyses of maternal drinking over four perinatal time points as predictors of maternal victimization at 2 years postpartum due to intimate partner violence. Women classified as higher risk drinkers over the study period faced significantly increased risk of physical abuse while parenting a 2-year-old child. Among non-drinking mothers, paternal binge drinking signaled additional risk, with clinical and programmatic implications.
