Mitigating and preventing substance use among adolescents requires approaches that address the multitude of factors that influence this behavior. Such approaches must be tested, not only for evidence of empirical effectiveness, but also to determine the mechanisms by which they are successful. The aims of the present study were twofold: 1) To determine the effectiveness of a school-based social...

Cannabis use is highly prevalent in late adolescence, but not all users experience significant negative consequences. Little information is available to identify the substance use patterns and risk factors of users who are at greater risk of experiencing negative consequences. In this prospective study, we aimed to empirically identify latent classes of substance use in adolescent cannabis user...

Extant literature reports a frequent co-occurrence of substance consumption and antisocial behaviors. It is also postulated, therefore, that risk and protective factors are shared by the two behaviors. The purpose of this research is to test this notion by exploring whether family and peer-individual risk and protective factors are similarly associated with unique and co-occurring substance con...

Children of affluent parents are often excluded in psychological research as they are considered to be at "low risk"; however, research is beginning to suggest that this previously under-studied population may be at risk for developing multiple problem behaviors, including substance use and externalizing problems. The current study aimed to extend the application of Problem Behavior Theory (PBT...
