This study used Latent Class Analysis (LCA) to examine whether multiple subgroups can be identified based on rule-breaking and aggressive behavior in school-based and at-risk adolescent samples. These groups were tested for differences in behavioral, emotional, personality and interpersonal correlates. Rule breaking and aggressive behavior co-occurred across all classes. School-based adolescents were classified as having minimal, minor or moderate antisocial problems. At-risk adolescents were classified as having mild, medium or severe antisocial problems. Generally, at-risk adolescents had higher levels of antisocial behavior, and greater severity of antisocial behavior was associated with more problems in various domains. Results differed however, for the school-based and at-risk samples with respect to emotional problems, sensation-seeking and peer conformity pressure. There is a need to jointly consider both non-aggressive rule-breaking behavior and aggressive behavior in prevention and intervention work, as it is insufficient to address isolated symptoms and problems in children and adolescents/
