We analyzed data from the Columbia County Longitudinal Study, initiated in 1960 by Eron et al. [1971], when the original sample of 856 children, all of the third graders in Columbia County, NY, was first assessed at Wave 1 of what has now became a 40-year longitudinal study. This project has generated a large amount of data concerning how aggression develops from childhood into adulthood [see Eron et al., 1971, 1991; Huesmann et al., 1984; Huesmann and Moise 1988; Kokko et al., in press; Lefkowitz et al., 1977], as well as how childhood and adolescent aggression negatively affect indices of adulthood success [e.g., Dubow et al., 2006, in press; Huesmann et al., 2006]. Although little has been published thus far about predicting adult criminality in this sample, Huesmann et al. [2002] found that aggressiveness at age 8 increased the risk for arrest by age 30. In this article, we extend this analysis to predicting criminality through age 48.
