A longitudinal study investigating TDM and adolescent health and development: Brain, Behavior and well-Being

项目总结--总体 这一P01计划拨款将建立一个完全整合的跨学科研究项目计划，并 科学核心，对于从根本上理解 青少年健康和发展、技术和数字媒体(TDM)。先前的证据表明 TDM与青少年危险行为的联系，如酒精行为增加和社交媒体暴露， 以及与青少年幸福感的关系，如改善社交情绪健康和同龄人社交媒体 关系。本提案中描述的项目的目标是解决迫切需要了解如何 TDM的暴露和使用影响多个发育领域和健康结果。三个PI都是 位于威斯康星大学麦迪逊分校，除了 突出的机构支持和资源，包括配套资金。这些项目包括：项目1：使用 TDM以了解青少年健康和危险行为的机制。项目2：使用功能磁铁 磁共振成像，以了解积极和消极的TDM体验如何与心理和行为相关 健康。项目3：使用混合方法评估自生成和其他生成的TDM内容作为 性和性别少数(SGM)和非SGM青少年的社会情绪幸福感。每个项目都利用 为期2年的纵向设计，并从共享参与者池中提取。各种数据收集方法 项目包括观察/测量数据，包括观察到的社交媒体内容和自我报告的功能磁共振数据 参与者通过调查和访谈的体验和认知，以及生态瞬时评估 捕获实时TDM曝光。为支持该计划，管理核心(管理核心)将提供 组织和管理支持，以安排计划协作者之间的定期会议，包括 学生参与研究，利用生物统计学支持并促进传播。这份P01提案将 包括招聘和保留核心(R&R核心)，支持跨项目共享参与者池， 并确保随着时间的推移而保留。P01计划将通过以下方式促进这些研究工作的协同 通过协作式纵向设计、统一的措施和共享的 参与者池，以便可以在项目内部和跨项目构建分析。本P01提案包括 优先向科学受众和威斯康星州的社区传播研究结果，以 联系那些参与这项研究的人。因此，这个<foreign lang=“English”>P01</foreign>节目将提高科学知识， 通过3个项目、行政核心和R&R核心的互动而获得的想法和成果。这 拟议的计划将提供必要的基础设施支持和科学方法 提供数据信息的理论和概念模型，阐述TDM暴露和使用如何影响发展 青少年的发展轨迹和健康结果。因为推动研究和发展的巨大潜力 可能的临床转化结果，这些相关的项目预示着改善预防的机会 以及青少年健康和TDM的干预方法。

PROJECT SUMMARY – OVERALL This P01 program grant will establish a fully integrated interdisciplinary program of research Projects and Scientific Cores that are essential to develop a fundamental understanding of the complex interplay between adolescent health and development, and technology and digital media (TDM). Previous evidence has illustrated TDM’s connections to adolescent risk behaviors such as increased alcohol behavior and social media exposure, as well as relationships to adolescent well-being such as improved socioemotional health and peer social media connections. The goal of the Projects described in this proposal is to address the urgent need to understand how TDM exposure and usage affect multiple developmental domains and health outcomes. The three PIs are all located at the University of Wisconsin-Madison, ensuring close collaboration and synergy, in addition to outstanding institutional support and resources, including matching funds. The Projects include: Project 1: Using TDM to understand mechanisms in adolescent health and risk behavior. Project 2: Using functional magnetic resonance imaging to understand how positive and negative TDM experiences relate to mental and behavioral health. Project 3: Using mixed methods to evaluate self- and other-generated TDM content as predictors of socioemotional well-being in sexual and gender minority (SGM) and non-SGM adolescents. Each Project utilizes a 2-year longitudinal design and draws from a shared participant pool. Data collection approaches across Projects include observed/measured data including observed social media content and fMRI data, self-reported participant experiences and perceptions via surveys and interviews, and Ecological Momentary Assessment to capture real-time TDM exposures. To support this program, the Administrative Core (Admin Core) will provide organizational and management support to arrange regular meetings across Program collaborators, involve students in the research, leverage biostatistical support and promote dissemination. This P01 proposal will include a Recruitment and Retention Core (R&R Core), supporting a shared participant pool across Projects, and ensuring retention over time. This P01 program will promote synergy in these research efforts through integrated data collection processes over a synergistic longitudinal design, aligned measures and a shared participant pool so that analyses can be structured within and across Projects. This P01 proposal includes a priority on dissemination of findings, both to scientific audiences and to the communities across Wisconsin to reach those who participated in this research. Thus, this P01 program will enhance the scientific knowledge, ideas and outcomes obtained through the interactions of the 3 Projects, the Admin Core and the R&R Core. This proposed program will provide both the infrastructure support and the scientific approach necessary to advance data-informed theories and conceptual models addressing how TDM exposure and usage impact developmental trajectories and health outcomes of adolescents. Because of the broad potential for advancing research and possible clinical translation of results, these connected Projects portend an opportunity to improve prevention and intervention approaches for adolescent health and TDM.
