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.
作为先前横断面研究的延伸，本研究采用前瞻性数据来检验积极的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。自 2017 年至 2019 年，在 3 个时间点，通过自我报告收集了来自 2327 名年轻成年大学生（平均年龄为 21.2；标准差为 2.1；54%为女性）的数据。结构方程模型用于检验中介模型。在基线从未使用过电子烟的人群中，较高的情绪调节预期——例如，相信电子烟使用会感觉良好、减少无聊和压力——中介了更高的基线社交媒体电子烟暴露对一年后电子烟使用起始的影响。在基线终生使用电子烟的人群中，较高的积极感觉、积极的“吸烟”体验和情绪调节预期信念中介了基线较高的社交媒体电子烟暴露对一年后增加当前电子烟使用的影响。社交媒体上的电子烟内容可能通过传达电子烟让人感觉良好和有助于减轻压力的感觉，促使年轻人尝试电子烟。社交媒体上宣传电子烟口味和电子烟作为香烟更清洁、更被社会接受的替代品的内容，可能会促使电子烟使用者增加电子烟的使用。预防电子烟使用起始和升级的努力可能需要针对社交媒体影响的结果预期信念。
