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.
Undergraduates ( = 1075; 72% female, 74% White) from seven US campuses completed an online survey between October 2019-March 2020.
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.
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.
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.
大学生使用电子烟的频率高于美国其他任何年龄段的人群。在对获得性准备模型的一种新颖应用中，我们研究了近端（例如，认知）和远端（例如，性格）影响因素如何解释电子烟的使用和依赖。
来自美国七个校区的本科生（ = 1075；72%女性，74%白人）在 2019 年 10 月至 2020 年 3 月之间完成了在线调查。
我们分别使用零膨胀泊松分布模型来建模电子烟的使用和依赖，冲动性作为自变量，电子烟的感知风险和益处作为中介变量。
冲动性较高的学生感知到更多的益处，因此报告了更多的电子烟使用和依赖。好奇心和朋友的使用促使了电子烟的使用，而压力管理和尼古丁则促使了持续使用。
对于冲动性较高的学生，电子烟干预措施应该针对他们量身定制，因为他们对电子烟的看法更为有利，并且应该提高管理压力和尼古丁渴望的技能。
