A manualized treatment package for anger control in boys ages 7 to 10 was investigated using a control group outcome design. The treatment package included modeling, rehearsal with self-talk problem-solving, daily report cards and a praise phase. At post-test treatment participants were significantly higher than controls on the Aggression Control factor of the Olweus Aggression Inventory (OAI) and the Compliment observation category. Control's scores were significantly higher than the treatment group's on the Dislike Factor of the Peer Status Rating Scale-Child Report Form and on the Threat observation category.
