PROJECT SUMMARY/ABSTRACT Children’s screen media use has increased dramatically in recent years. Greater screen use, especially during the evening hours, is routinely, though not unequivocally, associated with disruption of sleep including shorter sleep duration, difficulty falling asleep, and reduced overall sleep quality. Based in a wealth of research showing poor sleep health in childhood to robustly forecast a wide range of adverse outcomes (e.g., obesity, psychiatric disorders, poor cognitive and academic performance, emotion dysregulation, increased risk-taking behaviors, suicidality), current guidelines provided by virtually every major pediatric health organization/association recommend that children avoid use of electronic screens in the hour before bed. While perhaps intuitive, empirical evidence to support this guideline is largely cross-sectional. That is, causal effects of evening screen use on children’s sleep and circadian timing have not been sufficiently demonstrated nor have the mechanism(s) through which sleep disruption may occur been clarified. Experimental studies are therefore necessary to provide professionals and parents with evidence-based guidance and inform developmental research. The goal of the current study is to systematically test the impact of light exposure from screens as well as arousing media content on N=200 school-aged children’s (8 to 11 years) sleep regulation and circadian timing, in addition to next-day emotion regulation and executive functioning. Our novel ability to objectively assess and account for children’s daytime tablet use history will allow us to accurately isolate the effects of evening screen use on children’s sleep. Using a 4-group randomized, controlled design including assessment of typical sleep and media use followed by a 3-day experimental protocol, we plan to: 1) systematically test the effects of evening screen media use in the natural home environment on children’s sleep duration, sleep latency, and subjective sleep quality; 2) translate experimental research methods from the laboratory to the home environment to examine the impact of bright light emitted from screens and exposure to arousing media content on children’s sleep, circadian physiology, and physiological arousal; 3) examine the role of evening screen use on children’s next day executive functioning and emotion regulation. The proposed research addresses several critical gaps in scientific knowledge regarding the impact of evening screen media use on children’s sleep health, including elucidating the specific mechanism(s) through which potential negative impacts may occur. Results may directly inform national guidelines and policies regarding evening screen media use in all children.

项目摘要/摘要 近年来，儿童屏幕媒体使用的使用急剧增加。更大的屏幕使用，尤其是在 傍晚时期，尽管不是明确的，但与睡眠中断有关，包括较短的睡眠 睡眠持续时间，难以入睡，并降低了整体睡眠质量。基于大量研究表明 童年的睡眠健康不佳，以预测各种不良后果（例如肥胖症，精神病学） 疾病，认知能力差和学习成绩，情绪失调，增加冒险行为， 自杀性），几乎每个主要的儿科健康组织/协会提供的当前指南 建议儿童在睡觉前的小时内避免使用电子屏幕。虽然也许是直观的，但 支持该指南的经验证据在很大程度上是横断面的。也就是说，晚屏幕的因果影响 在儿童的睡眠和昼夜节律时机上使用尚未得到充分证明，也没有机制 可能会通过澄清睡眠中断的情况。因此，必须进行实验研究以提供 专业人士和父母具有基于证据的指导并为发展研究提供信息。目标的目标 当前的研究是系统地测试屏幕上光照的影响，并引起媒体内容 在n = 200年龄的儿童（8至11年）的睡眠法规和昼夜节律时机上 情绪调节和执行功能。我们客观评估和解释儿童的新颖能力 白天平板电脑使用历史记录将使我们能够准确隔离晚屏幕对儿童睡眠的影响。 使用4组随机，受控的设计，包括评估典型的睡眠和媒体使用 通过为期3天的实验协议，我们计划：1）系统地测试晚间屏幕媒体在 儿童睡眠时间，睡眠潜伏期和主观睡眠质量的自然家庭环境； 2） 将实验研究方法从实验室转换为家庭环境，以检查 屏幕上发出的明亮灯光并暴露于唤起儿童睡眠的媒体内容，昼夜节律 生理学和生理唤醒； 3）检查晚上屏幕使用在儿童第二天高管中的作用 功能和情绪调节。拟议的研究解决了科学的几个关键差距 关于晚间屏幕媒体使用对儿童睡眠健康的影响的知识，包括阐明 可能发生潜在负面影响的特定机制。结果可能直接告知 有关所有儿童晚间屏幕媒体使用的国家准则和政策。
