This report was inspired by OJJDP's "Comprehensive Strategy for Serious, Violent, and Chronic Juvenile Offenders." This strategy emphasized strengthening the family and core socializing institutions, implementing prevention programs that target key risk factors, identification of early potential offenders, and the use of graduated sanctions based on assessments of risks and need. The "Comprehensive Strategy" provides an excellent framework for understanding, preventing, and controlling SVJ offending. The current report uses the "Comprehensive Strategy" as a springboard and includes detailed quantitative analyses of risk and protective factors as well as of the effectiveness of prevention and intervention programs for SVJ offenders. It also aims to integrate the risk/protective factors and prevention/intervention program literature, so that programs are based more on research on influential factors, and conclusions about putative causal effects of factors are drawn from knowledge about the effectiveness of programs. Tabular data, figures, and references accompany the papers presented.
