Anxiety Symptoms and Alcohol-Related Problems among College Students: A Moderated-Mediation Model of Rumination and Emotion Dysregulation.

OBJECTIVES:  Prior research has individually linked rumination, anxiety, and emotion dysregulation to alcohol misuse, but limited research has examined a comprehensive model linking these variables together. The present study tested a moderated-mediation model to examine whether emotion dysregulation moderated the indirect association of anxiety symptoms on alcohol-related problems via ruminative thinking styles. Method: Participants were 448 college students who consumed alcohol in the previous month. A plurality of participants identified as being White, non-Hispanic (40.6%), female (68.6%), and reported a mean age of 22.75 (Median = 20.00; SD = 6.84) years. Results: Brooding and reflection subtypes of ruminative thinking mediated the association between anxiety symptoms and alcohol-related problems with higher rates of anxiety symptoms associated with higher ruminative thinking, which in turn was associated with more alcohol-related problems. Further, the indirect effect of anxiety symptoms on alcohol-related problems through ruminative thinking was stronger for individuals who reported high levels of emotion dysregulation compared to those with average and low levels of emotion dysregulation. Conclusions: In support of prior work, our results suggest that ruminative thinking, particularly brooding and reflection, are key mechanisms through which anxiety symptoms relate to problematic alcohol use, especially among individuals with high emotion dysregulation. Additional work is needed to test whether decoupling the associations between negative emotional states and ruminative thinking among college students with high emotion dysregulation is a viable intervention target to reduce problematic alcohol use.
