Social media use has been linked to poor adolescent sleep outcomes, but the mechanisms behind this association are not yet well understood. This study examines links between adolescents' social media habits, fear of missing out and sleep outcomes, using path analysis to evaluate a model of proposed underlying mechanisms.
Adolescents aged 12-18 years (N = 101) completed questionnaire measures.
Nighttime social media use was associated with later bedtimes, increased pre-sleep cognitive arousal, longer sleep onset latency and shorter sleep duration. Path analysis supported a model whereby fear of missing out predicted shorter sleep duration via two distinct mechanisms: (1) at a behavioural level, by driving late night social media use, which delays bedtimes; (2) at a cognitive level, by increasing pre-sleep cognitive arousal, thus further delaying sleep onset.
Efforts to develop and evaluate intervention strategies should therefore consider not only social media behaviours but also underlying cognitive factors, such as fear of missing out.
社交媒体的使用与青少年睡眠质量差有关，但目前尚不清楚这种关联的背后机制。本研究使用路径分析评估了一个潜在机制模型，探讨了青少年社交媒体习惯、错失恐惧与睡眠结果之间的联系。
12-18 岁的青少年（N=101）完成了问卷调查。
夜间社交媒体的使用与晚睡、睡前认知唤醒增加、入睡潜伏期延长和睡眠时间缩短有关。路径分析支持了这样一种模式，即错失恐惧通过两种不同的机制预测睡眠时间缩短：（1）在行为层面上，通过驱动深夜社交媒体使用，从而延迟睡眠时间；（2）在认知层面上，通过增加睡前认知唤醒，从而进一步延迟入睡时间。
因此，开发和评估干预策略的努力不仅应考虑社交媒体行为，还应考虑潜在的认知因素，如错失恐惧。
