At some point in their lives, most children go through a defiant phase in which they engage in verbal altercations with adults or other children. However, some children exhibit a pattern of violent behavior that can endanger themselves and those around them. Youth violence makes communities less safe, increases the cost of health care and is often accompanied by other problematic behaviors.
A 1999 landmark survey of U.S. high school students conducted by the Centers for Disease Control and Prevention found that more than a third of all students polled had been involved in a physical altercation. Male students were more likely to be involved in physical fighting: 44 percent of male high school students polled had been in a physical fight, whereas 27 percent of female high school students reported involvement in physical violence. The study also found that approximately one out of every seven students had been in a physical fight on school property, and that more than 10 percent polled had been injured badly enough to require medical attention.
