目的：我们对青少年和年轻人进行了具有全国代表性的调查，以研究电子烟结果预期与电子烟使用之间的关联。背景资料：近年来，青少年和年轻人使用电子烟的情况迅速增长，但很少有研究在全国代表性样本中研究这种行为背后的信念。方法：使用基于概率的网络面板对N = 1，298名青少年（13-17岁）和2，219名年轻人（18-25岁）进行了调查。参与者完成了一项调查，其中包括一项新的结果预期指标，检查了3个积极的（享受，社会影响，优于香烟）和2个消极的（健康问题，吸烟者协会）预期领域以及曾经使用过电子烟。结果：验证性因素分析显示，结果预期的因素结构与数据拟合良好。在单变量分析中，所有预期结果均与两个人群中的电子烟使用相关。在控制多个协变量的多元逻辑回归模型中，青少年中较高的预期享受与更大的电子烟使用可能性呈正相关（aOR = 2.10，p < .05）。在年轻人中，享受（aOR = 3.08，p < .001）与更大的使用可能性呈正相关，而健康问题（aOR = 0.70，p < .01）和吸烟者协会（aOR = 0.73，p < .05）与电子烟使用呈负相关。结论：这项研究表明，预期的享受与青少年和年轻人的电子烟使用密切相关。健康问题也可能在电子烟使用中发挥作用。电子烟的预防工作和未来的研究方向的影响进行了讨论。
Objectives: We conducted nationally representative surveys of adolescents and young adults to examine associations between e-cigarette outcome expectancies and e-cigarette use. Background: E-cigarette use among adolescents and young adults has grown rapidly in recent years, yet little research has examined the beliefs that may underlie this behavior among nationally representative samples. Methods: N = 1,298 adolescents (13-17) and 2,219 young adults (18-25) were surveyed using a probability-based web panel. Participants completed a survey that included a new outcome expectancy measure examining 3 positive (enjoyment, social influences, advantage over cigarettes) and 2 negative (health concerns, smoker association) expectancy domains and ever having used e-cigarettes [ever use]. Results: Confirmatory factor analyses demonstrated a good fit of the outcome expectancies' factor structure to the data. All outcome expectancies were associated with e-cigarette use in both populations in univariate analyses. In multiple logistic regression models controlling for several covariates, higher expected enjoyment was positively associated with a greater likelihood of e-cigarette use (aOR = 2.10, p < .05) among adolescents. Among young adults, enjoyment (aOR = 3.08, p < .001) was positively associated with a greater likelihood of use while both health concerns (aOR = 0.70, p < .01) and smoker association (aOR = 0.73, p < .05) were negatively associated with e-cigarette use. Conclusions: This study suggests that expected enjoyment is robustly associated with e-cigarette use among both adolescents and young adults. Health concerns may also play a role in e-cigarette use. Implications for e-cigarette prevention efforts and future research directions are discussed.
