Social Media Use, Sleep, and Suicidality in Adolescents

项目摘要 青少年自杀率在过去20年里有所上升，最近的新冠肺炎事件加剧了这一趋势 大流行前的风险因素，包括在线社交信息的增加。我们建议在线社交 给青少年发信息是一种“社会潮流”(一种环境上的“时间给予者” 昼夜节律)，以及深夜在线社交信息导致睡眠延迟。随着时间的推移, 睡眠开始延迟，加上青少年无法相移清醒时间，都会导致 管理日常压力的认知和情绪能力受损，导致总体脆弱性 研究表明，在白天和晚上，易感性会增加 青少年自杀的念头和行为。本研究的纵向研究将检验这些 在真实世界中使用(1)在线社交消息的文本提取 密集采样期，(2)生态瞬时评估(EMA)，和(3)可穿戴技术在 与预测算法相结合。这些发现将为干预措施提供信息，这些干预措施的范围从生态 瞬间干预以适应干预，如人际和社会节律疗法。

Project Summary Adolescent suicide rates have increased over the past two decades, with the recent COVID-19 exacerbating pre-pandemic risk factors including increases in online social messaging. We propose that online social messaging for adolescents serves as a “social zeitgeber” (an environmental “time giver” that synchronizes diurnal rhythm) and that late night online social messaging contributes to delays in sleep onset. Over time, delays in sleep onset in combination with inability to phase shift the wake time for adolescents, contributes to impairments in cognitive and emotional capacity for managing daily stress, resulting in overall vulnerability throughout the day as well as a shift of vulnerability to the evenings when research has shown increases in adolescent suicidal thoughts and behaviors. The present research longitudinal research will examine these processes in the real world using a combination of (1) text extraction of online social messaging during the intensive sampling period, (2) ecological momentary assessment (EMA), and (3) wearable technology in combination with predictive algorithms. Findings will inform interventions that can range from ecological momentary interventions to adaptations to interventions such as Interpersonal and Social Rhythm Therapy.
