In this paper, both longitudinal and treatment studies relevant to conduct disorder (CD) are reviewed, and a developmental approach to its prevention is presented. Outcome studies for the treatment of CD and antisocial behavior are first reviewed to demonstrate that, although none have been entirely successful, many interventions have powerful effects on various symptoms that comprise the disorder, highly predictive antecedents, and risk factors. Second, the development of CD and the potency and interrelationship among antecedent and mediating variables is traced through the preschool and early elementary school years. Third, an attempt is made to synthesize the developmental and treatment research findings to suggest possible integrations of interventions that are promising for future preventive trials in the preschool and elementary school periods. It is concluded that, whereas before the entry to school preventive interventions targeted entirely in the family setting may prove successful, after the transition to school multisetting interventions will be essential. Finally, three examples of new and multisetting prevention trials are briefly described.
