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福祉和健康至关重要，特别是在青春期， 这一时期的特点是更加重视同行关系和经验。 数字媒体 (TDM)，特别是社交媒体，可以与同行建立联系。 成为青少年越来越重要的交流形式，71％的青少年报告使用更多 超过一个社交媒体网站和 92% 的 13-17 岁青少年表示上网 然而，对 TDM 使用的评论表明，对于 TDM 和社会的影响尚未达成共识。 媒体使用对青少年福祉和健康行为的影响，发现积极、消极和无效的结果。 他们强调，几乎没有证据可以检验 TDM 使用与健康之间的潜在调节因素。 存在和健康结果，这限制了我们对影响感兴趣结果的因素的理解。 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具体方式。 例如，如果大量接触某些类型的 TDM（例如社交媒体），就会变得敏感。 青少年对其他人的观点更加敏感，他们可能会对社交等负面经历做出更强烈的反应 排斥，但可能会从社会包容的经历中受益更多，这种敏感性可能有助于解释混合现象。 当前的研究建议通过测量青少年的暴露程度来检验这一想法。 具有社交联系功能的社交媒体（从项目 1 和 3 中提取数据）（即喜欢、 然后我们将这些经历与他们的反应纵向联系起来。 社会包容和排斥的经历来预测健康和风险行为以及福祉 （从项目 1 和 3 中提取数据）并研究功能反应在整个社会转型过程中如何变化 从初中到高中的时期，这个时期与社会关系的变化、冒险精神和挑战有关。 这些数据不仅会检查与社交相关的缺陷。 媒体的使用会导致较差的福祉和不健康的行为，但也会检查社交媒体的优势 此外，媒体的使用以及它们与更好的福祉和健康行为的关系。 根据社交线索，这些数据可以帮助确定引导青少年参与社交媒体的方法， 该项目与当前的 RFA 保持一致，因为它测试了 TDM 的方式。 该项目特别符合本 RFA 的两个感兴趣领域：1) 对青少年时期 TDM 使用情况进行跨学科研究，采用多层次评估 神经发育，检查大脑功能和复杂行为的相互关联的发育变化，以及 2) 实时测量 TDM 暴露和使用情况以及这种使用情况如何调节青少年的行为。
