Conventional therapies for anger involve restructuring thoughts and beliefs to bring about a reduction in anger. These therapies often come within the schools of CBT (or cognitive behavioral therapy) like modern systems such as REBT (rational emotive behavior therapy). Research shows that people who suffer from excessive anger often harbor and act on dysfunctional attributions, assumptions and evaluations in specific situations. It has been shown that with therapy by a trained professional, individuals can bring their anger to more manageable levels. The therapy is followed by the so-called "stress inoculation" in which the clients are taught "relaxation skills to control their arousal and various cognitive controls to exercise on their attention, thoughts, images, and feelings. They are taught to see the provocation and the anger itself as occurring in a series of stages, each of which can be dealt with."
