The present study aimed to investigate the relationship between impulsivity-related personality traits based on the UPPS-P model and e-cigarette use. The study used a sample of mainly European adults and compared e-cigarette users with non-smokers, cigarette smokers and dual users (those who currently smoke cigarettes and use e-cigarettes). Additionally, the relationship between impulsivity-related traits and frequency and intensity of e-cigarette use was examined, while the main reasons for e-cigarette use were also assessed.
Participants were 720 adults (234 non-smokers, 164 smokers, 150 e-cigarette users, 172 dual users), who completed online questionnaires regarding sociodemographics, smoking/e-cigarette use behaviour, and impulsivity (UPPS-P scale).
Impulsivity-related traits did not significantly differentiate e-cigarette users from non-smokers. E-cigarette users showed lower levels of lack of perseverance than cigarette smokers, and they exhibited lower levels of negative and positive urgency than dual users. Negative urgency also significantly differentiated smokers and non-smokers, with smokers having higher levels of the trait. No significant results were found examining the relationship between the impulsivity-related traits and e-cigarette behaviour (number of days vaping per month, number of times vaping per day, and millilitres of e-liquid used per day). The main reason given for e-cigarette use was the perception that it is less harmful than cigarettes.
The present study found that trait impulsivity differentiated e-cigarette users from cigarette smokers and dual users, but did not differentiate e-cigarette users from non-smokers. Such findings are important to not only help us identify factors associated with e-cigarette use, but also to potentially inform treatment plans and decisions.
本研究旨在探讨基于UPPS - P模型的冲动性相关人格特质与电子烟使用之间的关系。该研究以主要为欧洲成年人的样本为对象，比较了电子烟使用者与非吸烟者、吸烟者以及双重使用者（即目前既吸烟又使用电子烟的人）。此外，还研究了冲动性相关特质与电子烟使用频率和强度之间的关系，同时评估了使用电子烟的主要原因。
参与者为720名成年人（234名非吸烟者、164名吸烟者、150名电子烟使用者、172名双重使用者），他们完成了关于社会人口统计学、吸烟/电子烟使用行为以及冲动性（UPPS - P量表）的在线问卷。
冲动性相关特质并未显著区分电子烟使用者与非吸烟者。与吸烟者相比，电子烟使用者表现出较低的缺乏毅力水平，并且与双重使用者相比，他们表现出较低的消极和积极冲动水平。消极冲动也显著区分了吸烟者和非吸烟者，吸烟者具有更高的消极冲动水平。在研究冲动性相关特质与电子烟行为（每月吸电子烟的天数、每天吸电子烟的次数以及每天使用的电子烟液毫升数）之间的关系时，未发现显著结果。使用电子烟的主要原因是认为其危害比香烟小。
本研究发现，特质冲动性区分了电子烟使用者与吸烟者和双重使用者，但未区分电子烟使用者与非吸烟者。这些发现不仅有助于我们识别与电子烟使用相关的因素，还可能为治疗计划和决策提供参考，具有重要意义。
