Notes: UPPS-P = Negative Urgency, Premeditation (lack of), Perseverance (lack of), Sensation Seeking, and Positive Urgency Impulsive Behavior Scale; β = standardized beta; CI = confidence interval. Univariate models for each UPPS-P facet tested interactions between each impulsivity facet and high-arousal/low-arousal context factor scores. For each univariate model, the left columns correspond to high-arousal context analyses, and the right columns correspond to low-arousal analyses. “Context” refers to the high- and low-arousal context factor scores; quadratic interactions (and their lower order main effects) were retained only if significant at p < .05.
