作为先前横断面研究的延伸,本研究采用前瞻性数据来测试积极结果预期信念作为社交媒体对年轻人电子烟使用进展影响的中介因素。 2017 年至 2019 年间,每 6 个月在 3 个时间点收集 2327 名年轻成人大学生(平均年龄 = 21.2;SD = 2.1;54% 女性)的自我报告数据。使用结构方程模型来测试中介模型。在基线从未使用过电子烟的人群中,较高的影响监管预期(例如,相信电子烟的使用会带来良好的感觉、减少无聊和压力)介导了较高基线的社交媒体电子烟暴露对一年后电子烟使用开始的影响。在基线终生电子烟使用者中,较高的积极感官、积极的“吸烟”体验和影响调节预期信念介导了基线时较高的社交媒体电子烟暴露对一年后当前电子烟使用增加的影响。社交媒体上的电子烟内容可能会传达电子烟让人感觉良好并有助于减轻压力的感觉,从而说服年轻人尝试电子烟。社交媒体上的电子烟内容宣传电子烟口味和电子烟作为更清洁和社会更容易接受的香烟替代品,可能有助于增加实验者对电子烟的使用。防止电子烟使用开始和升级的努力可能需要针对受社交媒体影响的结果预期信念。
As an extension of a previous cross-sectional study, this study employed prospective data to test positive outcome expectancy beliefs as mediators of social media’s influence on e-cigarette use progression among young adults. Self-report data were collected from 2327 young adult college students (Mean age = 21.2; SD = 2.1; 54% women) between 2017 and 2019, every 6-month, at 3 time-points. Structural equation modeling was used to test the mediational models. Among baseline never e-cigarette users, higher affect regulation expectancies—e.g., beliefs that e-cigarette use results in feeling good, reduced boredom and stress—mediated the effects of higher baseline social media e-cigarette exposure on e-cigarette use onset one year later. Among baseline lifetime e-cigarette users, higher positive sensory, positive “smoking” experience, and affect regulation expectancy beliefs mediated the effects of higher social media e-cigarette exposure at baseline on increased current e-cigarette use one year later. E-cigarette content on social media may persuade young adults to try e-cigarettes by imparting the sense that e-cigarettes make one feel good and help reduce stress. E-cigarette content on social media that promote e-cigarette flavors and e-cigarettes as cleaner and a socially more acceptable alternative to cigarettes may work to escalate e-cigarette use among experimenters. Efforts to prevent e-cigarette use onset and escalation may need to target the outcome expectancy beliefs influenced by social media.
