Using new data from the Columbia County Study, in this article we first extend the analysis that Huesmann and Moise [1998] reported for age 8–30 to aggressive and antisocial behavior in middle adulthood at age 48. Second, we examine the extent to which different patterns of continuity in aggressive and antisocial behavior from middle childhood through early adulthood (i.e., life-course-persistent low or high aggression, adolescent- or child-limited aggression, late-onset aggression in early adulthood) predict negative outcomes as well as positive outcomes in middle adulthood.
