Although e-cigarette use is on the rise among youth and adults, there is little understanding of the individual difference factors at a cognitive level of analysis for e-cigarette beliefs and quit behavior.
The present investigation sought to test a theoretically driven interactive model of positive expectancies for e-cigarettes and anxiety sensitivity (fear of the consequences of anxiety) among 551 adult e-cigarette users (50.6% female, Mage = 35.2 years, SD = 10.1).
Results indicated a significant interaction between positive expectancies for e-cigarette use and AS was significantly related to greater perceived benefits of e-cigarette use, greater perceived risk of e-cigarette use, and more serious attempts for trying to quit e-cigarettes. The significant interaction effect for each dependent variable was evident over and above the main effects as well as the covariates of sex, income, education, and concurrent combustible cigarette use. The form of this interaction indicated that e-cigarette users higher in AS who also maintained more positive outcome expectancies for e-cigarette use reported more perceived benefits as well as more perceived risk of e-cigarette use and engaged in more (failed) attempts to quit e-cigarettes.
Overall, the current data suggest that individual differences in AS and positive expectancies may represent two important factors to consider in e-cigarette beliefs and quit attempts.
This study provides the first empirical evidence of a transdiagnostic construct (anxiety sensitivity) in relation to e-cigarette use and how it interplays with positive expectancies for e-cigarette use beliefs and behavior. These novel data suggest that future clinical research may benefit by understanding the potential therapeutic role of anxiety sensitivity and expectancies for e-cigarette use behavior.
尽管电子烟在青少年和成年人中的使用呈上升趋势，但对于电子烟信念和戒烟行为，在认知层面上，个体差异因素的了解甚少。
本研究试图在 551 名成年电子烟使用者（50.6%为女性，Mage = 35.2 岁，SD = 10.1）中测试一个理论驱动的电子烟积极预期与焦虑敏感（对焦虑后果的恐惧）的交互模型。
结果表明，电子烟使用的积极预期与焦虑敏感之间存在显著的交互作用，焦虑敏感与电子烟使用的感知益处更大、感知电子烟使用风险更大、戒烟尝试更严重有关。在每个因变量上，显著的交互作用效应不仅明显超过了主要效应，还超过了性别、收入、教育和同时使用可燃香烟的协变量。这种交互作用的形式表明，焦虑敏感程度较高且对电子烟使用的积极预期较高的电子烟使用者报告说，电子烟的感知益处更大，感知风险也更大，并且戒烟尝试更频繁（失败）。
总体而言，目前的数据表明，焦虑敏感和积极预期的个体差异可能是电子烟信念和戒烟尝试中需要考虑的两个重要因素。
本研究首次提供了一个跨诊断构念（焦虑敏感）与电子烟使用之间关系的实证证据，以及它如何与电子烟使用的积极预期相互作用。这些新数据表明，未来的临床研究可能受益于理解焦虑敏感和电子烟使用行为的预期在治疗中的潜在作用。
