Seminar paper from the year 2010 in the subject Psychology - Clinical Psychology, Psychopathology, Prevention, ( Atlantic International University ), language: English, abstract: It may be accepted that at some point in a child's life, they will display oppositional and defiant behaviour (Riley, 1997). When do the occasional rule-breaking, the sulking and whining, and the fits and tantrums become a cause for concern?

It is quite evident that conduct disorder is a more severe behavioural condition than oppositional defiant disorder. If the characteristics of both disorders mentioned here seem rather simil
