In considering alcohol abuse, the author points out that alcohol abuse frequently emerges as a prominent risk factor in a variety of family problems. Despite media attention, alcoholism continues to account for most substance abuse problems in the United States and is the most frequently mentioned form of substance abuse contributing to family problems in general and domestic violence in particular. Clinical observations of the behaviors of abusers and their victims have led to a consensus among experts about behavioral characteristics of participants in domestic violence. Abusers project blame onto others, victims tend to be socially isolated, and both abusers and victims become more disoriented with repeated alcohol-related incidents. Research also shows a link between alcoholism and child abuse, abused children often grow up to be alcoholic adults, and domestic violence is more prevalent among substance abusers than among non-substance abusers. Following a discussion of the effects of alcohol on violent behavior the author concludes that alcohol abuse is a key causative agent in domestic violence.
