ABSTRACT
This paper examines predictors of violence in a sample of 177 clinic-referred 7 to 12 year-old boys annually assessed using multi-informant clinical interviews and comprehensive questionnaires over an eleven-year period. The analyses in the present paper include participants who have completed at least one adult assessment (n=139) at age 18 or 19. Analyses: Violence included shootings, biting off extremities, and fighting resulting in paralysis or coma reported at 18 or 19. Analyses included factors present in childhood (through age 12) or early adolescence (through ate 15). Results: After controlling for ethnicity, urban environment, and low SES, the final logistics regression model included early Conduct Disorder (p=.008), presence of 2 or more siblings in household during childhood (p=.009), early alchol use (p=.02) and marijuana use in adolescence (p=.12). Variables that were individually associated with serious injury, but were removed from the final model, were poor communication with parent, paternal APD, broken family and early adolescent CDE. Discussion: The strength of both CD and alcohol use by the age of 12 as predictors of violence in youth adulthood strongly suggests early key foci for the resources used in the prevention of serious violence.
