The aim of the present study was to investigate the effects of aggression control group training on female adolescents in one of the educational institutions in Tabriz to reduce or control their aggressive behavior. The statistical population consisted of all female adolescents of the institution totaling 24 people, who were randomly divided into two groups (experimental and control). Before the training course, a per-test was performed. The experimental group received eight sessions of instructions. After the completion of the course, a post-test was performed both for experimental and control groups. The results indicate that aggression management group training sessions can cause a significant effect on the reduction and control of the physical and verbal agression and anger of female adolescents. Therefore, aggression management group training can change behavior problems such as aggression.
