Abstract

Background: Electronic cigarette (e-cigarette) use has risen dramatically in the United States among young adults; however, little is understood about potential factors that are related to e-cigarette use and maintenance among this population. Fatigue severity is one promising individual difference factor, as past work indicates that it is related to greater withdrawal symptoms and greater dependence on e-cigarettes, and more barriers to quitting. In addition, anxiety sensitivity and severe fatigue are both uniquely related to poor e-cigarette use outcomes; yet, no known studies have examined whether these individual difference factors are related to e-cigarette outcomes among young adults. Method: The current study sought to examine the unique and interactive effects of anxiety sensitivity and fatigue severity in predicting a variety of e-cigarette outcomes among 685 (69.1% female; M_age = 19.61 years, SD = 1.44) young adult e-cigarette users. Results: Results indicated that anxiety sensitivity was significantly associated with greater barriers for cessation (β = .63, p <.001) and e-cigarette cravings (β = .67, p =.001), but not dependence. Fatigue severity was significantly associated with greater e-cigarette dependence (β = .58, p <.001), barriers to cessation (β = 1.56, p <.001), and e-cigarette cravings (β = 3.34, p <.001). The interactive effects of anxiety sensitivity and fatigue severity did not significantly predict the outcomes. Discussion: Results suggest that anxiety sensitivity and fatigue severity independently predict greater e-cigarette maintenance factors among young adults. The current investigation highlights the importance of targeting anxiety sensitivity and fatigue severity among young adult e-cigarette users.

背景：美国年轻人中电子烟的使用率急剧上升；然而，人们对这一人群中与电子烟使用和维持相关的潜在因素知之甚少。疲劳严重程度是一种有希望的个体差异因素，因为过去的研究表明，它与更严重的戒断症状和对电子烟的更大依赖以及更多的戒烟障碍有关。此外，焦虑敏感性和严重疲劳都与不良的电子烟使用结果独特相关；然而，尚无已知的研究检验这些个体差异因素是否与年轻人的电子烟结果相关。方法：本研究旨在检验 685 名（69.1% 女性； M_年龄= 19.61 岁， SD = 1.44）年轻电子烟青少年中焦虑敏感性和疲劳严重程度在预测各种电子烟结果方面的独特交互作用。用户。结果：结果表明，焦虑敏感性与更大的戒烟障碍（β = .63， p <.001）和电子烟渴望（β = .67， p = .001）显着相关，但与依赖无关。疲劳严重程度与更大的电子烟依赖性 (β = .58, p <.001)、戒烟障碍 (β = 1.56, p <.001) 和电子烟渴望 (β = 3.34, p % 3C.001) 显着相关<.001)。焦虑敏感性和疲劳严重程度的交互作用并不能显着预测结果。讨论：结果表明，焦虑敏感性和疲劳严重程度独立预测年轻人中更大的电子烟维持因素。 目前的调查强调了针对年轻电子烟使用者的焦虑敏感性和疲劳严重程度的重要性。
