The research also analyzed the level of parent-child agreement in the report of aggression. The study used the Structured Clinical Interview for DSM-IV Axis 1 Disorders to identify MDD. The study assessed adolescents’ aggressive behavior using an adapted version of the Brown-Goodwin Assessment for Lifetime History of Aggression; the Measure of Aggression, Violence, and Rage in Children; and the Buss-Durkee Hostility Inventory-Adapted Version. Results indicated high levels of aggressive behavior in adolescents with MDD. The amount and type of aggression did not differ by gender. Results also indicated poor correspondence between parent and adolescent reports of aggression, which was most marked for females. Findings indicated that aggressive behaviors are highly prevalent in depressed youths and are similar in males and females. However, parents tend to underreport and may not be aware of aggressive behavior that occurs outside the home, particularly among females. Tables and 49 references (Author abstract modified)
