Alcohol & Aggression

Alcohol, Violence and Aggression

This web page discusses the association between alcohol consumption, and violence and aggression. Understanding the nature of these associations is essential to breaking the cycle of alcohol misuse and violence.

Scientists and nonscientists alike have long recognized a two-way association between alcohol consumption and violent or aggressive behavior.

Not only may alcohol consumption promote aggressiveness, but victimization may lead to excessive alcohol consumption.

Violence may be defined as behavior that intentionally inflicts, or attempts to inflict, physical harm. Violence falls within the broader category of aggression, which also includes behaviors that are threatening, hostile, or damaging in a nonphysical way.

Extent of the Alcohol-Violence Association

Based on published studies, the percentages of violent offenders who were drinking at the time of the offense are as follows:

  • up to 86 percent of homicide offenders 
  • 37 percent of assault offenders 
  • up to 60 percent of sexual offenders  
  • 57 percent of men and 27 percent of women involved in marital violence 
  • 13 percent of child abusers.

These figures are the upper limits of a wide range of estimates. In another community-based study, 42 percent of violent crimes reported to the police involved alcohol, although 51 percent of the victims interviewed believed that their assailants had been drinking.

Aggressive Alcohol Behavior May Be "Learned"

Alcohol consumption may promote aggression because people expect it to. For example, research using real and mock alcoholic beverages shows that people who believe they have consumed alcohol begin to act more aggressively, regardless of which beverage they actually consumed. Alcohol-related expectancies that promote male aggressiveness, combined with the widespread perception of intoxicated women as sexually receptive and less able to defend themselves, could account for the association between drinking and date rape.

In addition, a person who intends to engage in a violent act may drink to bolster his or her courage or in hopes of evading punishment or censure. The motive of drinking to avoid censure is encouraged by the popular view of intoxication as a "time-out," during which one is not subject to the same rules of conduct as when sober.
