PROJECT SUMMARY In the U.S., adolescents' loneliness increased 100%, from 18% to 37% from 2012 to 2018. Meanwhile, social media use has grown sharply. In 2022, adolescents reported being constantly online twice as often compared to 2014-15, with 95 % of U.S. teens using YouTube, 67% TikTok, 62% Instagram, and 59% Snapchat. However, little research investigated the relationship between the two trends. Loneliness is a risk factor for psychological and physical problems with long-term health effects related to biological mechanisms, including stress response. Large-scale cohort studies reported that online time was positively associated with adolescents' loneliness and that online time displaced time for in-person social interaction with peers. In adults, in-person social interactions are associated with higher well-being than online communication. However, we do not know to what extent this link is similar in the adolescent population. Also, previous measures were mainly based on self-reports of ill-being and screen time. Hence, it is now urgent to establish to what extent in-person and online social interactions predict adolescents' loneliness as a risk factor for mental health problems, using objective indicators. Our long- term goal is to determine which social media experiences promote adolescents' mental well-being, defined as the presence of happiness, thriving, and flourishing. Using an intensive longitudinal mixed- method design, biomarker-informed, we will address the following aims: 1. Quantify the short- and long- term bi-directional relationships between online/offline interaction on loneliness and mental well-being. EMAs and trace data will be collected for 2 weeks and individual and contextual factors will be assessed through a baseline survey. The same participants will be followed up after 1 year to determine long-term effects on loneliness, social media use, mental ill- and well- being, and resilience. 2. Assess the validity of the short- and long-term quantitative findings in Aim 1 by collecting qualitative data24 on the bi-directional relationships between online/offline social interactions, loneliness, and well-being, by running focus groups after each quantitative data analysis phase. 3. Test the feasibility and utility of a “digital biomarker” using hair cortisol concentration (HCC). HCC has been increasingly used as an objective indicator of stress. Loneliness is experienced as a stressor, and we will determine to what extent digital footprints and loneliness correlate with adolescents' HCC. 1

项目摘要 在美国，青少年的孤独感增加了100%，从2012年的18%增加到2018年的37%。同时， 社交媒体的使用急剧增长。2022年，青少年报告经常上网的频率是现在的两倍。 与2014-15年相比，95%的美国青少年使用YouTube，67%使用TikTok，62%使用Instagram，59%使用 Snapchat.然而，很少有研究探讨这两种趋势之间的关系。孤独是一 与生物学相关的长期健康影响的心理和身体问题的风险因素 机制，包括应激反应。大规模队列研究报告称， 与青少年的孤独感正相关，上网时间取代了面对面社交的时间， 与同行的互动。在成年人中，面对面的社交互动与更高的幸福感相关， 在线交流。然而，我们不知道这种联系在青少年中的相似程度 人口此外，以前的措施主要是基于自我报告的疾病和屏幕时间。 因此，现在迫切需要确定面对面和在线社交互动在多大程度上预测 青少年的孤独感作为心理健康问题的危险因素，使用客观指标。我们长久以来- 长期目标是确定哪些社交媒体体验能促进青少年的心理健康， 幸福，幸福。使用密集的纵向混合- 方法设计，生物标记知情，我们将解决以下目标： 1.量化线上/线下之间的短期和长期双向关系 孤独感和心理健康的相互作用。将收集2周的EMA和跟踪数据 并将通过基线调查评估个人和背景因素。相同的 参与者将在1年后进行随访，以确定对孤独感，社交媒体和社交媒体的长期影响。 使用，精神疾病和幸福，以及恢复力。 2.评估目标1中短期和长期定量结果的有效性， 关于在线/离线社交互动之间的双向关系的定性数据24， 孤独感和幸福感，通过在每个定量数据分析阶段后运行焦点小组。 3.使用头发皮质醇浓度（HCC）测试“数字生物标志物”的可行性和实用性。 HCC越来越多地被用作压力的客观指标。孤独是一种体验， 压力源，我们将确定数字足迹和孤独感在多大程度上与 青少年肝癌 1
