The anger management program was developed based on the principles of Rational Emotive
Behavior Theory (Ellis & Whiteley, 1979) and utilized eight activities from the Passport Program (Vernon,1998) that were relevant to anger management (for a protocol of activities see Appendix A). Themes of these activities include: changing beliefs about situations to reduce anger, building empathy, recognizing
signs of anger, and practicing anger control through role-playing.
