Children and Violence

Not all children enjoy the "carefree" days of childhood. Unfortunately, when things start to go wrong, people often despair of being able to repair the damage.
This is a time of high concern about violent behavior by young people. As a nation, we are in a period of reflection as to what can be done to stem this tide. Helping young people avoid or overcome emotional problems in the wake of violence or disaster is one of the most important challenges a parent, teacher, or mental health professional can face. Moreover, children often face violence in their own homes.
NIMH conducts research looking at violence in young people, as well as the effects of violence on young people.
