Social media use is associated with poor sleep outcomes. We aimed to extend previous research by examining how measures of social media use would affect two sleep characteristics: sleep quality and insomnia symptoms. In addition, we tested a serial mediation model linking social media use to sleep through increases in negative social comparison and pre-sleep cognitive arousal. Participants were 830 emerging adults (ages 18-30) who were recruited for an online survey study in February 2024. The sample was 63.1% female, with an average age of 24. We examined three measures of social media use: duration (minutes of daily use), frequency (number of weekly visits to social media platforms), and emotional investment (attachment to and integration of social media into daily life). Consistent with our hypothesis, greater emotional investment in social media and more frequent social media use were associated with poorer sleep quality and greater insomnia severity. We also found evidence supporting our hypothesized serial mediation model: emotional investment in social media and more frequent social media use were associated with increased negative social comparison, which subsequently increased pre-sleep cognitive arousal, which then led to poorer sleep outcomes. Our findings suggest that negative social comparison and pre-sleep cognitive arousal are important mechanisms linking social media use to poor sleep outcomes. Future studies should aim to test this serial mediation model using longitudinal data and experimental methods.
使用社交媒体与睡眠质量差有关。我们旨在通过研究社交媒体使用的测量指标如何影响两种睡眠特征：睡眠质量和失眠症状，来扩展先前的研究。此外，我们测试了一个系列中介模型，该模型通过负面社会比较和睡前认知唤醒的增加，将社交媒体使用与睡眠联系起来。参与者为830名新兴成年人（年龄在18至30岁之间），他们于2024年2月被招募参与一项在线调查研究。样本中女性占63.1%，平均年龄为24岁。我们考察了三种社交媒体使用的测量指标：时长（每日使用分钟数）、频率（每周访问社交媒体平台的次数）和情感投入（对社交媒体的依恋以及社交媒体融入日常生活的程度）。与我们的假设一致，对社交媒体的情感投入越大以及使用社交媒体越频繁，与睡眠质量越差和失眠严重程度越高相关。我们还发现了支持我们假设的系列中介模型的证据：对社交媒体的情感投入和更频繁地使用社交媒体与负面社会比较的增加有关，这随后又增加了睡前认知唤醒，进而导致更差的睡眠结果。我们的研究结果表明，负面社会比较和睡前认知唤醒是将社交媒体使用与睡眠质量差联系起来的重要机制。未来的研究应旨在使用纵向数据和实验方法来测试这个系列中介模型。
