Abstract

INTRODUCTION: Identifying adolescents at risk for marijuana use who can be targeted for intervention efforts is critical. Certain personality traits are strongly associated with substance use, including marijuana use. We investigated the associations of impulsivity (and its subscales sensation seeking and lack of planning), aggression, and neuroticism with marijuana use (lifetime and frequency of past 12-month use) in a national sample of adolescents.

METHODS: We used data from the National Comorbidity Survey: Adolescent Supplement, a nationally representative, cross-sectional study of 8495 U.S. adolescents aged 14 to 18 years. We calculated adjusted prevalence ratios and odds ratios to assess associations of the five personality scales with lifetime use and frequency of past 12-month use and examined gender as a potential moderator of these associations.

RESULTS: Each of the personality traits was positively associated with lifetime use (all p < 0.001). Impulsivity (the total scale and both subscales) and aggression (all p < 0.05) were positively associated with frequency of past 12-month use. The neuroticism-lifetime use association was stronger among girls (p < 0.001) than boys (p < 0.05), and the associations of impulsivity and lack of planning with frequency of use were significant only among girls, with moderate female users reporting higher levels of the personality scales than infrequent users (both p < 0.01).

CONCLUSIONS: Our study highlights the potential importance of identifying personality traits, specifically disinhibition-related traits such as impulsivity and aggression, to reduce and prevent adolescent marijuana use.
