For instance, antisocial behavior suggestive of conduct disorder is associated with single parent status, parental divorce, large family size, and young age of mothers.[1] However, these factors are difficult to tease apart from other demographic variables that are known to be linked with conduct disorder, including poverty and low socioeconomic status. Family functioning and parent-child interactions also play a substantial role in childhood aggression and conduct disorder, with low levels of parental involvement, inadequate supervision, and unpredictable discipline practices reinforcing youth's defiant behaviors. Peer influences have also been related to the development of antisocial behavior in youth, particularly peer rejection in childhood and association with deviant peers.[1] Peer rejection is not only a marker of a number of externalizing disorders, but also a contributing factor for the continuity of the disorders over time.
