ABSTRACT

Numerous studies have highlighted the relation between drinking behavior and alcohol references on social media. However, most studies on substance-use-related social media effects rely on self-report data, and it remains unclear whether individuals can accurately report their online alcohol-related communication. This study contributes to this line of research by examining whether individuals accurately report their alcohol-related self-sharing behavior on social media and what factors contribute to a misestimation of this behavior. A sample of 149 Belgian college students (64.3% females, M_age = 21.33, SD = 1.49) participated in this study, who were asked survey questions on their general and alcohol-related social media use. In addition, all posts they shared on their Instagram profiles between April 1^st, 2019, and March 31^st, 2020, were captured and coded. The results indicated a positive association between the counted and self-reported frequencies of sharing alcohol posts on Instagram. However, most participants overestimated how often they shared this content. The perceived injunctive norms and sharing alcohol posts for entertainment motives were the only significant predictors of this overestimation. We conclude that this overestimation may be a result of subtle social desirability processes and a misremembrance of what has been shared.

摘要

许多研究都强调了社交媒体上饮酒行为与酒精引用之间的关系。然而，大多数关于物质使用相关社交媒体影响的研究都依赖于自我报告数据，个人是否能够准确报告他们与酒精相关的在线交流尚不清楚。这项研究通过检查个人是否准确地报告了他们在社交媒体上与酒精相关的自我分享行为，以及哪些因素导致了对这种行为的错误估计，从而为这一领域的研究做出了贡献。149 名比利时大学生（64.3% 女性，M_年龄 = 21.33，SD = 1.49）参与了这项研究，他们被问及关于他们的一般和与酒精相关的社交媒体使用的调查问题。此外，他们在 4 月 1 日之间在 Instagram 个人资料上分享的所有帖子2019 年^{st和 2020 年3}月 31 日被捕获并编码。结果表明，在 Instagram 上分享酒类帖子的计数频率和自我报告频率之间呈正相关。然而，大多数参与者高估了他们分享这些内容的频率。为娱乐动机而感知的禁令规范和分享酒精帖子是这种高估的唯一重要预测因素。我们的结论是，这种高估可能是微妙的社会期望过程和对共享内容的错误记忆的结果。
