Dynamic classification places individuals into categories based on changes in levels of delinquent behavior over time. These analyses assess the extent to which specific constructs are associated with changes in the delinquency status of individuals. Constructs of the social development model, including opportunities for conventional involvement, skills for conventional involvement, rewards for conventional involvement, proactive family management, bonding to conventional society, opportunities for antisocial involvement, antisocial interactions, perceived rewards for antisocial involvement and norms against drug use, were significantly associated with change in delinquent behavior over time. Many of the constructs were particularly salient in distinguishing between youths who remained involved in delinquency and youths who deescalated or desisted from delinquent behavior during this period.
