Conduct disorder is a childhood disorder that is often resistant to treatment. Current treatment methods often focus on separate interventions for each environment that the child or adolescent is exhibiting antisocial behavior. Additionally the focus is on the behavior of the child and often does not focus on the family unit or the biology behind the behavior. This paper will look at a multimodal and multisystemic treatment that will combine treatment of several areas into one cohesive treatment plan, as well as addressing issues other than the antisocial behavior such as the family unit, attachment style, and follow-up to treatment to maintain gains on the reduction of antisocial behavior as important factors in the intervention and treatment of Conduct Disorder by providing examples through case studies to provide examples of application.
