Intimate partner violence (IPV) is a significant public health and economic problem, which also increases the risks for child maltreatment. One attribute that may contribute to both IPV and poor parenting is hostility. Moreover, the link between hostility and these outcomes may be mediated by substance use, such that more hostile individuals are at greater risk for using drugs and alcohol, leading them to engage in more aggressive and rejecting behavior toward their partners and children. We tested this possibility in sample of 132 fathers. Additionally, we explored whether hostility and substance use had interactive effects on IPV and parenting by examining moderated-mediation models. The results show that substance use mediated the relationship between hostility and all IPV and parenting outcomes. Furthermore, this mediated relationship was moderated by substance use level for parenting outcomes, but not IPV. In the case of parenting, the mediated path from hostility to aggressive and rejecting parenting only occurred for those high in substance use. Limitations and implications for prevention and treatment of IPV and aggressive and rejecting parenting are discussed. Aggr. Behav. 41:205-213, 2015. © 2014 Wiley Periodicals, Inc.
