The primary purpose of this study was to conduct a prospective examination of the relationship between childhood conduct problems and five outcomes in adolescence– namely, Physically violent offenses; Non-violent offenses; Deviant lifestyle; Consumption of tobacco, cannabis, or alcohol; and Meeting the symptom count diagnostic criteria for Conduct Disorder (CD) – while controlling for a series of sociodemographic factors, family characteristics and adolescent experiences. Logistic regression analyses were used to determine if childhood conduct problems in the Canadian National Longitudinal Survey of Children and Youth (NLSCY) Cycle 1 contributed to negative outcomes in adolescence in NLSCY Cycle 4. This was a prospective, population-based study of 3,725 adolescents (12-15 years old) in the NLSCY Cycle 4 (2000-2001) who were 6-9 years old in NLSCY Cycle 1 (1994-95). Childhood conduct problems were found to be associated with Non-violent offenses and Consumption of tobacco, cannabis, or alcohol in adolescence, but they were not found to be associated with Physically violent offenses or Deviant lifestyle in adolescence. Furthermore, children with conduct problems before the age of 10 were more likely to meet the symptom count diagnostic criteria for CD in adolescence.
