Kids 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 12 and younger who express their anger in ways that harm others, themselves, animals, and personal property. The workbook is especially helpful for children who have experienced complex trauma and are hurt, angry, and bereft as a result. Adults can use the exercises in this workbook to guide children 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. Young people can learn to manage their anger without parental involvement but they do even better when parents are involved and do whatever it takes to be emotionally available to their children.
