Effects of alcohol on human aggression: an integrative research review.

This review used quantitative and qualitative techniques to integrate the alcohol and aggression literature. The primary purpose of the review was to determine if a causal relation exists between alcohol and aggression. The main meta-analysis included 30 experimental studies that used between-subjects designs, male confederates, and male subjects who were social drinkers. Studies using other designs or subject populations were integrated with meta-analytic procedures when possible and summarized descriptively when not. The results of the review indicate that alcohol does indeed cause aggression. However, alcohol effects were moderated by certain methodological parameters.
