Background and aims: Studies have demonstrated that ecological momentary assessment (EMA) can effectively capture within-person variations in impulsive states and that this relates to alcohol use. The current study aimed to examine the daily trajectories of five facets of impulsivity prior to and following drinking initiation. Additionally, we explored how race, sex, baseline trait impulsivity facets, and ADHD may moderate this relation.
Design and setting: EMA was used to collect real-time data at 6 semi-random time points and self-initiated reports of drinking onset throughout the day over a 10-day period Measurements Five state and trait impulsivity facets were assessed via the UPPS-P. Naturalistic alcohol use, ADHD history, and demographic characteristics were also assessed PARTICIPANTS: Participants were 135 adult drinkers from a larger study examining alcohol response for Black and White adults with and without a history of childhood ADHD FINDINGS: Generalized estimating equations showed that the linear trajectory of negative urgency significantly increased prior to drinking. Following drinking initiation, the linear trajectory of sensation seeking significantly decreased. There was not significant change in the trajectories of positive urgency, lack of premeditation and lack of perseverance before or after drinking initiation. Additionally, race and ADHD history moderated the trajectory of sensation seeking and race moderated the trajectory of lack of planning.
Conclusions: Findings highlight the possibility of identifying proximal changes in impulsivity facets prior to and after initiation of drinking. Results can be used to inform real-time interventions that target risk periods to ultimately decrease alcohol use.
