The goal of this study is to examine the effectiveness two forms of psychotherapy (also known as "talk therapy" ) for individuals with anger and aggression problems. Anger and aggression are everywhere - on the road, in the schools, at little league games, at home, and at work. In this study we are testing usefulness of anger management techniques in reducing symptoms of Intermittent Explosive Disorder (IED) and impulsive, aggressive behavior.

Qualified participants will be randomly assigned to 12 1-hour sessions of either cognitive-behavioral therapy or supportive psychotherapy.

Participation in this study will require 16 visits over approximately 4 months with 3 follow-up sessions over a 12 month period. Therapy is provided at no cost and each study participant will receive a comprehensive psychological assessment. Two types of talk therapy are being offered in this study. One form of therapy focuses on thought and behaviors associated with anger and aggression. This type of therapy is known as cognitive behavioral therapy. The other type of therapy focuses on the individuals' feeling about their anger /aggression and the situations that lead to this anger. This is known as supportive therapy. The form of therapy you are given will be randomly determined (like by flipping of a coin).
