[Characteristics associated with conduct disorder, oppositional defiant disorder and comorbidity]

The purpose of the study is to determine whether pattern of association with psychological, social and family correlates are similar for oppositional defiant disorder (ODD), conduct disorder (CD), and ODD + CD. Participants were 336 boys and girls (age range from 6 to 13 years) in treatment for disruptive behaviour disorders including 123 children with ODD, 39 with CD "only", and 174 with ODD + CD. Results showed that parent's antisocial personality and poor supervision characterized children with CD whereas children with ODD presented with more attention deficit/hyperactivity symptoms and inconsistent discipline. All these correlates characterized children with ODD + CD. These results suggest the importance of taking into account these differences between groups in children treatment.
