Social service systems rarely acknowledge the status of men as fathers in the conceptualization and delivery of treatment for substance abuse or domestic violence. Although there has been extensive focus on the treatment of mothers who abuse substances, are victims of intimate partner violence (IPV) (defined as physical aggression and/or psychological abuse and control at the hands of an intimate partner), or maltreat their children there has been little consideration of the need for interventions for fathers with histories of co-morbid IPV and substance abuse. It is estimated that between 10 and 17.8 million children are witness to violence in their homes each year. National and regional samples indicate 50-70% of families impacted by IPV and the typically co-occurring substance abuse have children under the age of seven. Large percentages of these men continue to live with or have consistent contact with their young children despite aggression and substance use.
