Abstract
Objective
College students use electronic nicotine delivery systems (ENDS) more often than any other US demographic group. In a novel application of the acquired preparedness model, we examined how proximal (e.g., cognitions) and distal (e.g., dispositional) influences accounted for ENDS use and dependence.
Participants
Undergraduates (N = 1075; 72% female, 74% White) from seven US campuses completed an online survey between October 2019-March 2020.
Methods
We modeled ENDS use and dependence, respectively, as zero-inflated Poisson distributions with impulsivity as an independent variable and perceived risks and benefits of e-cigarettes as mediators.
Results
Students higher in impulsivity perceived more benefits and, in turn, reported greater ENDS use and dependence. Curiosity and friends’ use motivated ENDS initiation; stress management and nicotine motivated continued use.
Conclusions
ENDS interventions should be tailored to students higher in impulsivity, as they hold more favorable perceptions of ENDS, and should enhance skills to manage stress and nicotine cravings.

Notes
1 Given that 34% of participants reporting past 30-day ENDS use also reported past 30-day combustible cigarette use, we examined models predicting ENDS benefits, ENDS risks, and ENDS frequency that included past 30-day combustible cigarette use as a covariate. Although combustible cigarette use was significantly and positively associated with ENDS benefits and ENDS frequency, the addition of this variable did not attenuate any of the significant associations in these models, suggesting that the effect of impulsivity on ENDS use was not confounded by cigarette use.
