Although electronic cigarette (e-cigarette) use is now a common substance use behavior, there is little understanding of the individual difference factors related to e-cigarette use beliefs and dependence. The present investigation sought to test a theoretically-driven model of anxiety sensitivity as an explanatory element in a worry-e-cigarette beliefs and dependence model. Participants included 558 adult e-cigarette users (51.4% female; 35.2 years, SD = 10.1) who were nationally recruited via an online survey system. Participants completed a single survey that assessed their mood and e-cigarette behavior and beliefs. Results supported a statistically significant indirect pathway for worry in relation to perceived benefits of e-cigarettes, e-cigarette positive outcome expectancies, and e-cigarette dependence via anxiety sensitivity; effect sizes were small. The indirect effects were evident when accounting for several theoretically relevant covariates (sex, income, education, concurrent cigarette use, and neuroticism). This study provides the first empirical evidence of the role of anxiety sensitivity in the relation between worry and e-cigarette use beliefs and behavior, which may represent a novel intervention target.
尽管电子烟（e-cigarette）的使用现在是一种常见的物质使用行为，但对于与电子烟使用信念和依赖相关的个体差异因素知之甚少。本研究旨在测试焦虑敏感性的理论驱动模型，作为担心电子烟信念和依赖模型的解释因素。参与者包括 558 名成年电子烟使用者（51.4%为女性；35.2 岁，标准差=10.1），他们通过在线调查系统在全国范围内招募。参与者完成了一项单一的调查，评估了他们的情绪和电子烟行为和信念。结果支持了一种统计学上显著的间接途径，即担忧与电子烟的感知益处、电子烟的积极结果预期以及通过焦虑敏感性导致的电子烟依赖之间存在关联；效应大小较小。当考虑到几个理论上相关的协变量（性别、收入、教育、同时吸烟和神经质）时，间接效应是明显的。这项研究提供了焦虑敏感性在担忧与电子烟使用信念和行为之间关系中的作用的第一个经验证据，这可能代表一个新的干预目标。
