What is oppositional defiant disorder?
Oppositional defiant (say: ah-puh-zish-uh-null dee-fie-ant) disorder, or ODD, is a behavior condition that affects children and teens. Those who have it are angry, argumentative and defiant much more often than others in their age group. The behaviors associated with ODD have a negative effect on the child's or teen's relationships and ability to do well in school and at home.
