The Role of Impulsivity, Anger, Verbal Ability, and Abstract Reasoning in Emerging Adults’ Treatment Outcomes
Journal Title: Journal of Addiction & Prevention - Year 2013, Vol 1, Issue 2
Abstract
Motivational interviewing (MI), a brief, client-centered intervention, has shown promise in reducing problem drinking. However, many questions remain regarding how to improve effectiveness of this intervention. Based on prior work indicating the importance of individual difference factors in response to MI interventions, this study explicitly evaluated the influence of empirically-indicated and theoretically-indicated individual difference factors (i.e., impulsivity, anger, verbal ability, abstract reasoning) in predicting treatment response. The sample included 53 problem drinkers (58.5% female; 54.9% Caucasian; 29.4% Hispanic; M age = 20.02 years). Multiple regression analyses indicated that verbal ability, anger, and impulsivity predicted reductions in quantity of drinking (drinks per drinking day) at the one month follow-up. Specifically, we observed a three-way interaction between verbal ability, anger, and impulsivity, whereby youth with either high or low verbal ability benefitted from treatment, with anger and impulsivity serving as limiting factors. Together, these data highlight the complex relationship between salient and indicated individual difference factors (impulsivity, anger, abstract reasoning, and verbal ability) in terms of treatment outcomes, as well as the relevance of examining these relationships directly with younger samples.
