Teens get angry. Anger is normal and natural. When expressed appropriately, anger is a means of communication and builds relationships. When combined with physical and verbal aggression, however, anger is destructive. This workbook is for young people 13 and older who express their anger in ways that harm others, themselves, animals, and personal property. The workbook is especially helpful for teens who have experienced complex trauma and are hurt, angry, and bereft as a result. Adults can use the exercises in this workbook to guide teens to deal constructively with the sources of their anger and to guide them to prosocial ways of expressing anger and other emotions associated with their anger.
