According to the Journal of Abnormal Child Psychology, "Disruptive behavior disorders include two similar disorders: oppositional defiant disorder (ODD) and conduct disorder (CD). Common symptoms occurring in children with these disorders include:
- defiance of authority figures,
- angry outbursts,
- and other antisocial behaviors such as lying and stealing.
It is felt that the difference between oppositional defiant disorder and conduct disorder is in the severity of symptoms and that they may lie on a continuum often with a developmental progression from ODD to CD with increasing age."
