背景和目的：有人提出，增加屏幕时间有助于提高青少年戒酒率。我们认为，这一命题取决于在何种程度上，一种类型的屏幕时间促进社会规范。我们研究了社会规范是否介导了酒精使用与i）社交媒体，ii）电视和iii）视频gaming.Design之间的关联：区分两个随时间变化的因素的多水平模型：人与人之间的影响和人内的影响。我们使用了一项随机对照试验的数据，该试验旨在检查针对个性的药物使用计划的效率。（47%女性，平均年龄= 12.7岁，标准差= 0.5岁）从大蒙特利尔地区的31所学校招募。我们估计了三种类型的屏幕时间之间的联系（社交媒体、电视和视频游戏）、与酒精相关的社会规范和酒精使用。社会规范介导了社交媒体使用和饮酒之间的关联，（β = 0.09，95% CI = 0.08，0.11，p = 0.000）和人内水平（β = 0.02，95% = 0.01，0.03，p = .000）以及在人内水平上电视使用和酒精使用之间的关联（β = 0.01，95% CI =-0.004，0.01，p = .000）。社会规范并没有调解视频游戏和饮酒之间的关联。结论：与酒精相关的社会规范被证明在相关和纵向水平上调解社交媒体使用之间的关联，以及在纵向水平上酒精使用和电视使用与酒精使用之间的关联，这可能意味着这些促进了对酒精使用的积极社会规范，从而增加青少年的饮酒行为。
Background and aims: It has been proposed that increased screen time contributes to increasing rates of adolescents abstaining from alcohol use. We argue that this proposition depends on the extent to which a type of screen time promotes social norms. We examined whether social norms mediated the association between alcohol use and i) social media, ii) television, and iii) video gaming.Design: Multilevel models distinguishing between two time-varying factors: between-person effects and within-person effects. We used data from a randomized-controlled trial examining the efficiency of a personality-targeted substance use programme.Participants: 3612 adolescents (47% female, mean age = 12.7, SD = 0.5 years) were recruited from 31 schools in the Greater Montreal area.Measurements: We estimated the association between three types of screen time (social media, television, and video gaming), alcohol-related social norms, and alcohol use.Findings: Social norms mediated the association between social media use and alcohol use at both the between-person (beta = 0.09, 95% CI = 0.08, 0.11, p = .000) and within-person level (beta = 0.02, 95% = 0.01, 0.03, p = .000) and association between television use and alcohol use at the within-person level (beta = 0.01, 95% CI = - 0.004, 0.01, p = .000). Social norms did not mediate the association between video gaming and alcohol use.Conclusions: Alcohol-related social norms were shown to mediate the association between social media use, both at a correlational and longitudinal level, and the association between alcohol use and television use and alcohol use, at a longitudinal level, which may imply that these promote positive social norms towards alcohol use, subsequently increasing adolescents' drinking behaviour.
