This article evaluates the utility of social development model constructs t
o assess the correlates of onset, escalation, deescalation, and desistance
of delinquent behavior, from age 12 to age 15, using a dynamic classificati
on approach. Dynamic classification places individuals into categories base
d on changes in levels of delinquent behavior over time. These analyses ass
ess the extent to which specific constructs are associated with changes in
the delinquency status of individuals. Constructs of the social development
model (SDM), including opportunities for conventional involvement, skills
for conventional involvement, rewards for conventional involvement, proacti
ve family management, bonding to conventional society, opportunities for an
tisocial involvement, antisocial interactions, perceived rewards for antiso
cial 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 beha
vior during this period. Implications for preventive interventions and crim
inological theory are discussed.
