PROJECT SUMMARY – PROJECT 2 Social connectedness and inclusion are essential for well-being and health, particularly during adolescence, a period characterized by an increased salience placed on peer relationships and experiences. Technology and digital media (TDM), particularly social media, has the affordance of connecting with peers. In fact, TDM has become an increasingly important form of communication for adolescents, 71% of adolescents report using more than one social media site and 92% of adolescents between the ages of 13-17 years old report going online daily. Reviews on TDM use, however, suggest that there is not consensus on the impact of TDM and social media use on well-being and health behaviors among adolescents, finding positive, negative, and null results. They highlight that little evidence exists that examines potential moderating factors between TDM use and well- being and health outcomes, which limits our understanding of what influences outcomes of interest. Thus, there is an urgent need to fill this gap. Effects associated with TDM use may depend on specific ways that adolescents use TDM. For example, if high levels of exposure to certain kinds of TDM, such as social media, sensitize adolescents to other people’s opinions, they may be more reactive to negative experiences such as social exclusion, but may benefit more from experiences of social inclusion. This sensitivity may help explain the mixed findings within the literature. The current study proposes to test this idea by measuring adolescent’s exposure to social media (drawing data from Projects 1 and 3) that have the affordances of social connectedness (i.e., likes, comments, number of friends or followers). Then we will relate these experiences longitudinally to their reactivity to experiences of social inclusion and exclusion to predict health and risk behaviors as well as well-being (drawing data from Projects 1 and 3) and examine how changes in functional reactivity across the social transition period from middle to high school, a period associated with changes in social ties, risk-taking, and challenges to well-being, may influence these relationships. This data will not only examine deficits associated with social media use that lead to poorer well-being and unhealthy behaviors, but will also examine the strengths of social media use and how they relate to better well-being and healthy behaviors. Further, if adolescents are sensitized to social cues, the data can help identify ways to help steer adolescents towards social media engagement that leads to greater well-being and healthier behaviors. This project aligns with the current RFA as it tests how TDM usage affects health behavior. This project specifically aligns with two areas of interest for this RFA: 1) interdisciplinary studies of TDM usage across adolescence employing multi-level assessments of neurodevelopment to examine interrelated developmental changes in brain function and complex behavior, and 2) real-time measures of TDM exposure and usage and how this usage regulates adolescents’ behavior.

项目摘要 - 项目2 社会联系和包容对于幸福感和健康至关重要，尤其是在青少年期间 期间的特征是增强了同伴关系和经验的显着性。技术和 数字媒体（TDM），尤其是社交媒体，具有与同行联系的负担。实际上，TDM有 成为青少年越来越重要的交流形式，有71％的青少年报告使用更多 一个社交媒体网站和92％的青少年在线报告的年龄在线报告 日常的。但是，对TDM使用的评论表明，就TDM和社会的影响没有共识 媒体对青少年的幸福感和健康行为的使用，发现正面，负面和无效的结果。 他们强调的是，很少有证据表明TDM使用与良好的情况下可能会调节潜在的调节因素 存在和健康结果，这限制了我们对影响感兴趣结果的原因的理解。那，那里 迫切需要填补这一空白。与TDM使用相关的效果可能取决于青少年的特定方式 使用TDM。例如，如果高水平接触某些TDM，例如社交媒体，敏感 对他人意见的青少年，他们可能对社交等负面经历更具反应性 排除，但可能会从社会包容的经验中受益更多。这种敏感性可能有助于解释混合 文献中的发现。当前的研究建议通过衡量青少年的暴露来测试这一想法 社交媒体（从项目1和3中汲取数据），具有社交联系的能力（即喜欢， 评论，朋友或追随者的数量）。然后，我们将纵向将这些经验与它们的反应性联系起来 社会包容和排斥以预测健康和风险行为以及幸福感 （从项目1和3中绘制数据）并检查社会过渡过程中功能反应性的变化 从中学到高中的时期，与社会关系变化，冒险和挑战有关的时期 幸福，可能会影响这些关系。这些数据不仅会检查与社会相关的定义 媒体使用会导致较差的幸福感和不健康的行为，但也将检查社会的优势 媒体使用及其与更好的健康和健康行为的关系。此外，如果青少年很敏感 对于社交线索，数据可以帮助确定帮助青少年参与社交媒体参与的方法 导致更大的幸福感和更健康的行为。该项目与当前RFA一致，因为它测试了TDM 用法会影响健康行为。该项目特别与此RFA感兴趣的两个领域保持一致：1） 跨青少年使用TDM使用的跨学科研究，采用多层次评估 神经发育以检查大脑功能和复杂行为的相互关联的发展变化，以及 2）TDM暴露和使用的实时测量以及这种用法如何调节青少年的行为。
