Aggression

Aggression is a common problem among schoolchildren and results in negative psychological, educational, and social outcomes for both aggressors and victims. This entry considers this aggression from both sides, that is, the side of the aggressors and the side of their victims. More specifically, it defines the terms aggression and peer victimization and reviews prevalence estimates of each. It also reviews the consequences of aggression for both aggressors and victims, as well as the antecedents or risk factors for each. This entry then moves beyond these generalities to discuss some of the subtypes of aggression and victimization. Finally, it offers some conclusions that can be drawn from the existing research and describes likely future directions for studying aggression.
