摘要：The mechanisms that underlie how negative affective traits influence problematic alcohol use and attentional biases are not well understood. The current article sought to characterize mechanisms that drive problematic alcohol use and attentional biases. Three undergraduate student studies were conducted (n = 510, 429, and 38). Negative urgency partially mediated the effects of negative affectivity (B for indirect effect = .119, CI = .09 – .16) and affect lability (B for indirect effect = .928, CI = .47 – 1.45) on problematic alcohol use. Activation level of hostility predicted increased variance in problematic alcohol consumption (R2 change = .01, β = .16, p = .02) above trait valence. Negative urgency predicted alcohol attentional biases over and above valence and activation (β = 2.23, p = .05). Negative urgency is a prime mechanism by which negative affective traits influence problematic alcohol consumption.
