Oppositional defiant disorder
Toggle: English / Spanish
Oppositional defiant disorder is a pattern of disobedient, hostile, and defiant behavior toward authority figures.
This disorder is more common in boys than in girls. Some studies have shown that it affects 20% of school-age children. However, most experts believe this figure is high due to changing definitions of normal childhood behavior, and possible racial, cultural, and gender biases.
This behavior typically starts by age 8, but it may start as early as the preschool years. This disorder is thought to be caused by a combination of biological, psychological, and social factors.

- Angry and resentful of others
- Argues with adults
- Blames others for own mistakes
- Has few or no friends or has lost friends
- Is in constant trouble in school
- Loses temper

- Is touchy or easily annoyed
To fit this diagnosis, the pattern must last for at least 6 months and must be more than normal childhood misbehavior.
The pattern of behaviors must be different from those of other children around the same age and developmental level. The behavior must lead to significant problems in school or social activities.
