Recent theoretical advances related to the development and course, including persistence and desistance, of antisocial behaviors and conduct problems, violent behaviors, and related problem behaviors are discussed. Integrative theoretical models, including the Dynamic Developmental Systems (DDS), are discussed. Aspects of the DDS model regarding the development of and change in antisocial behavior and violence across adolescence and early adulthood are illustrated with findings from the Oregon Youth Study, an ongoing, long-term examination of the causes and consequences of antisocial behavior for a community-based sample of men (and their romantic partners) who were raised in neighborhoods with high delinquency rates. Preventive implications of the model are discussed.
