Definition of Conduct Disorder (CD) & Oppositional Defiant Disorder (ODD)


CD and ODD may be diagnosed when a child is defiant, aggressive and anti-social to a greater extent than expected for their age. They often misread situations and have difficulty empathising with others and interpret others’ behaviour as aggressive which makes them responds with aggression.


ODD is less severe than conduct disorder, it is prevalent in around 2% of girls and 5% of boys. ODD is likely a combination of a child’s home environment and inherited factors. CD can either have an early onset (by the age of 10) or an adolescent onset (more common). It is four times more common in boys and the prevalence is approximately 6%.
