Background: Although the relation between impulsive-irresponsible psychopathic traits and substance use is well-documented, the path to developing substance use problems is less understood in adolescents with these characteristics.
Objectives: To examine the associations between psychopathy, anxiety, and substance use motives and a mechanism by which anxiety and alcohol and marijuana coping motives mediate the relation between psychopathic traits and substance use-related problems.
Methods: A sample of 185 at-risk adolescent males from a residential military-style program reporting past alcohol or marijuana use (M age = 16.74) participated in the study.
Results: Impulsive-Irresponsible psychopathic traits were uniquely and incrementally predictive of alcohol and marijuana use-related problems and anxiety. Anxiety and coping motives appeared to partially explain the association between impulsivity-irresponsibility and substance use-related problems.
Conclusions/importance: Findings suggest that youth expressing impulsive-irresponsible psychopathic traits may engage in problematic substance use at least partly as a function of heightened anxiety and a subsequent desire to alleviate distress by using alcohol or marijuana to cope.
Keywords: Anxiety; drinking motives; marijuana use motives; psychopathy; substance use.
