RAGE-Control: Teaching Emotional Self-regulation Through Videogame Play

The purpose of this study is to evaluate the use of Regulate and Gain Emotional Control (RAGE-Control), a biofeedback video game, in combination with brief instruction in relaxation skills as an intervention for symptoms of anger and aggression in children and adolescents. Half of the research participants will learn relaxation techniques and practice them using the RAGE-Control videogame. The other half of the participants will learn relaxation techniques and play a similar videogame without the biofeedback component. The investigators hypothesize that participants in the RAGE-Control group will show a greater reduction in symptoms of anger and aggression than those in the non-RAGE-Control group.
