ABSTRACT
The interrelation of childhood aggression, early and late adolescent delinquency, and drug use was explored. Data were obtained for the subjects when they were 5–10 years old. Follow-up interviews were conducted when the subjects were between 13–18 years old and again when they were 15–20 years old. A LIS-REL analysis of the three waves of data indicated that childhood aggression is a precursor of adolescent drug use and delinquency, and that early adolescent drug use is correlated with contemporaneous delinquency as well as with later drug use and delinquency.
