Proactive and reactive aggression in delinquent adolescents: Relations to aggression outcome expectancies

Investigated whether the relation between aggression and the tendency to ex pect positive outcomes for aggressive behavior is specific to the proactive subtype of aggression (as opposed to the reactive subtype). In a sample of 86 incarcerated adolescent boys ages 13 to 18, we measured outcome expecta ncies far aggression using audiotaped hypothetical vignetter. Far each part icipant, staff members completed proactive and reactive aggression racing s cales. Regression analyses revealed that the relation between aggression an d outcome expectancies was indeed specific to proactive aggression. Further more, this finding was supported regardless of whether outcome expectancies were assessed using vignetter describing proactive-aggressive behavior or those describing reactive-aggressive behavior We discuss these findings and argue that interventions to reduce proactive or reactive aggression should differ from each other by addressing the specific social cognitive process es involved in each type of aggression.
