ABSTRACT

The present longitudinal study (N = 596, M_{age at baseline} = 16.96, SD =.78) combines an interdependent social media effects approach with Slater’s reinforcing spirals model. As such, it is the first study to test a triple spiral between self-sharing of and exposure to alcohol-related content on social media, self-sharing and drinking behavior, and exposure and drinking behavior. We thereby differentiate between within-level and between-level relationships using a random intercepts cross-lagged panel model (RI-CLPM). The results indicate that there is a positive significant relationship between sharing, exposure, and consumption at the between-person level: Across waves, individuals who reported higher alcohol consumption also reported more frequent self-sharing, and those who reported more frequent self-sharing also reported more frequent exposure. Within-person change in self-sharing, exposure, and consumption are associated cross-sectionally, but these relationships do not endure over time. These results demonstrate that alcohol-related communication on social media effects may reflect a subgroup of heavy drinking adolescents who also share about their drinking behavior.

摘要

本纵向研究（N = 596，M_基线年龄 = 16.96, SD =.78) 将相互依赖的社交媒体效果方法与 Slater 的强化螺旋模型相结合。因此，这是第一项测试在社交媒体上自我分享和接触酒精相关内容、自我分享和饮酒行为以及接触和饮酒行为之间的三重螺旋的研究。因此，我们使用随机截距交叉滞后面板模型 (RI-CLPM) 来区分级别内和级别之间的关系。结果表明，人与人之间的分享、暴露和消费之间存在显着的正相关关系：跨波，报告更高酒精消费的个人也报告更频繁的自我分享，而那些报告更频繁的自我分享还报告了更频繁的接触。自我分享、暴露、和消费在横截面上是相关联的，但这些关系不会随着时间的推移而持久。这些结果表明，社交媒体上与酒精相关的交流可能反映了一部分酗酒青少年也分享了他们的饮酒行为。
