Overview | Symptoms | Treatment

Definition:

A pattern of negativistic, hostile, and defiant behavior towards an authority figure. There is an absence of violation in the social norms.

Causes and Risks

This disorder is more prevalent in boys than girls and is found in some studies to be as high as 20% of the school age population, though this may be over inflated due to economic, cultural, and racial biases. The onset typically begins by age 8. The cause of this disorder is unknown, and may be due to a combination of biology and parenting or environmental factors.
