The U.S. Department of Health and Human ServicesTrusted Source describes behavioral disorders as involving “a pattern of disruptive behaviors in children that last for at least 6 months and cause problems in school, at home, and in social situations”.
Mental, emotional, and behavioral disorders in childhood can cause long-term problems that may affect the health and well-being of children, families, and communities. Treating a child’s mental health problems as soon as possible can help children reduce problems at home, in school, and in forming friendships. It can also help with healthy development into adulthood.A public health approach to children’s mental health includes promoting mental health for all children, providing preventive intervention to children at risk, and providing treatment for children with identified disorders. Psychological therapy is a key component to improving mental health.

The most common behavioral disorders in children are:
- attention deficit hyperactivity disorder (ADHD)
- oppositional defiant disorder (ODD)
- conduct disorder (CD)
