They then participated in 12 anger management training sessions, after which they were re-tested. Repeated measures analysis of variance indicated significant differences, suggesting that anger management training may be an effective treatment strategy for reducing aggressiveness and providing coping skills to adolescent offenders with histories of violent crimes and aggressive behaviors.
