A longitudinal investigation of alcohol use and aggression in adolescence

Data from a prospective, longitudinal study of males and females tested at age 12, 15 and 18 years are used to study the relationship between alcohol use and aggression. Prevalence rates for alcohol use are similar for males and females. However, prevalence rates for aggressive behavior and alcohol-related aggression among females are lower than those for males and too low to permit meaningful analysis. Two series of nested structural equation models examine the interrelationships between alcohol use and aggressive behavior over time for all males in the sample and for male alcohol users only. The findings indicate that early aggressive behavior leads to increases in alcohol use and alcohol-related aggression, but that levels of alcohol use are not significantly related to later aggressive behavior. Thus, the data suggest that alcohol-related aggression is engaged in by aggressive people who drink. These data lend support to other research that indicates that early aggressive and antisocial behavior is predictive of later alcohol-related problems.
