Recent studies have shown associations among combat experience, PTSD, anger and hostility, and involvement in violence. Clinical observations of veterans enrolled in the Substance Use/Posttraumatic Stress Disorder Team (SUPT) program at the San Francisco Veterans Affairs Medical Center revealed relatively high levels of anger and aggressive behavior, including physical assaults and property damage. In response to this anger and aggressive behavior, an anger management treatment was added to the SUPT program's treatment of substance abuse and PTSD. Anger management consisted of a 12-week cognitive-behavioral group treatment. Session topics included identifying the physical, emotional, and situational cues to anger, developing individualized anger-control plans, recognizing and altering destructive self-talk, utilizing time-out, practicing conflict resolution techniques, and using the group to discuss and evaluate high-risk anger situations. Special attention was given to self-monitoring anger-escalating behavior (using an anger meter) and avoiding negative consequences. This article describes the components of the anger management treatment. A clinical vignette is also presented to illustrate the benefits of anger management treatment.
