DURHAM, N.C. -- Aggressive children are less likely to become violent criminals or psychiatrically troubled adults if they receive early intervention, says a new study based on more than two decades of research. "These findings from researchers at Duke, Pennsylvania State and Vanderbilt universities and the University of Washington are based on the Fast Track Project, a multi-faceted program that is one of the largest violence-prevention trials ever funded by the federal government. Beginning in 1991, the researchers screened nearly 10,000 5-year-old children in Durham, Nashville, Seattle and rural Pennsylvania for aggressive behavior problems, identifying those who were at highest risk of growing up to become violent, antisocial adults. Nearly 900 children were deemed at high risk, and of those, half were randomly assigned to receive the Fast Track intervention, while the other half were assigned to a control group. Participating children and their families received an array of interventions at school and at home. Nineteen years later, the authors found that Fast Track participants at age 25 had fewer convictions for violent and drug-related crimes, lower rates of serious substance abuse, lower rates of risky sexual behavior and fewer psychiatric problems than the control group. "We can prevent serious violence and psychopathology among the group of children who are highest-risk," said Duke's Kenneth Dodge. "That's the essential finding from this study. It provides the strongest evidence yet that, far from being doomed from an early age, at-risk children can be helped to live productive lives." Dodge directs the Duke Center for Child and Family Policy and is the William McDougall Professor of Public Policy at Duke's Sanford School of Public Policy. The program's positive effects held true across four different sites around the country, among both males and females and among both white and African-American children. The study appears online Sept. 15 in the American Journal of Psychiatry. From first through 10th grade, the Fast Track children received reading tutoring and specialized intervention aimed at improving self-control and social-cognitive skills. Parents learned problem-solving skills through home visits and parent training groups. When program participants turned 25, researchers reviewed court records and conducted interviews with participants and control group members, as well as individuals who knew the participants well. Along with fewer criminal convictions, Fast Track participants had lower rates of antisocial personality disorder and avoidant personality disorder, lower rates of risky sexual behavior and lower rates of harsh parenting. The latter finding suggests that the intervention may interrupt the inter-generational cycle of problem behavior. Fast Track is among very few studies to test the long-term effect of environment on children's development through a clinical trial. It provides strong evidence for the critical role environment plays in shaping a child's development. "This study adds to the experimental evidence for the important role that environment plays," Dodge said. "Genes do not write an inalterable script for a child's life. And not only does the environment matter greatly in a child's development, we've shown that you can intervene and help that child succeed in life." Fast Track's positive effects do not come cheap. The 10-year intervention costs $58,000 per child. However, that cost should be weighed against the millions of dollars that each chronic criminal costs society in imprisonment and harm to others, Dodge said. "Prevention takes a considerable investment, but that investment is worth it," Dodge said. "Our policies and practices should reflect the fact that these children can have productive lives." In future studies, Dodge and his colleagues plan to examine the cost-benefit question more closely. ### The research was supported by grants from the National Institute of Mental Health (NIMH R18 MH48043, R18 MH50951, R18 MH50952, R18 MH50953, K05MH00797 and K05MH01027), the Department of Education (grant S184U30002) and the National Institute on Drug Abuse (NIDA grants DA16903, DA017589, K05DA015226, and P30DA023026). The Center for Substance Abuse Prevention and the National Institute on Drug Abuse also provided support through a memorandum of agreement with the NIMH.
