Growing up in a digital world: A synergistic approach to understanding media use in children ages 1-8 years

项目总结 数字媒体访问的快速增长伴随着对复杂、实时的研究的匮乏 家庭媒体背景和社会认知结果，部分原因是缺乏综合衡量 工具。为了迎接这一挑战，PI的跨学科研究团队开发了一种多方法、可扩展、 性价比高的工具包称为家庭媒体曝光综合评估(CAFE)工具包。这个 工具包旨在捕捉早期媒体曝光的内容和背景(Barr等人，2020；Radesky等人 Al.，2020a)。虽然这个工具包代表着在描述家庭媒体生态方面向前迈出了实质性的一步， 在了解媒体曝光对儿童结果的影响方面取得的进展也受到缺乏的限制 在具有代表性的大型纵向数据集中，跟踪内容质量的难度在不断变化 媒体环境，以及缺乏快速分享和分析结果的机制，在理论上驱动 举止。为了克服该领域的这些限制，本研究计划的首要目标是 建议是检查媒体使用的轨迹-描述背景、内容和有问题的 使用媒体-在1200名1至7岁的不同儿童中，评估时间 采用队列序贯设计研究情绪调节与社交能力的关系。研究报告 该计划包括三项纵向研究，收集跨越整个年龄范围的三个队列的数据(1- 3、3-5、5-7岁)。在项目期间收集的新数据将与以前收集的数据进行比较 在COVID大流行期间，使用相同的工具包来检查大流行是如何改变媒体曝光的 媒体曝光与社会情感结果之间的关系。这篇文章中描述的工作 应用程序还将产生研究基础设施，以提高对媒体质量进行编码的效率 内容，该领域的一个瓶颈。最后，数据将被集成、共享、可视化和分析 共享分析研究中心。这项拟议的研究意义重大，因为它将是第一个协同效应 努力利用对家庭媒体生态的大型、多样化、纵向的全面评估 样本，以确定儿童早期有问题的媒体使用的前因以及特定媒体使用 支持儿童早期社会和情感发展的模式。建议的工作具有创新性。 因为它(1)使用了多方法、全面地评估家庭媒体生态；(2)应用了 生态视角，研究媒体效应和家庭系统内的社会情感发展；(3) 通过协同科学最大限度地提高影响和效率；(4)在不断变化的环境中简化内容编码 媒体环境；以及(5)构建用于清理、集成和分析共享数据的协作平台 以供重复使用。

Project summary Rapid growth in access to digital media is accompanied by a scarcity of research examining complex, real-time family media context and sociocognitive outcomes, driven in part by a lack of comprehensive measurement tools. To meet this challenge, the PI’s interdisciplinary research team developed a multi-method, scalable, cost-effective toolkit called the Comprehensive Assessment of Family Media Exposure (CAFE) Toolkit. The toolkit is designed to capture the content and context of early media exposure (Barr et al., 2020; Radesky et al., 2020a). While this toolkit represents a substantial step forward in characterizing the family media ecology, progress in understanding the effects of media exposure on child outcomes has also been limited by the lack of large and representative longitudinal datasets, the difficulty of tracking quality of content in an ever-changing media environment, and the lack of a mechanism to rapidly share and analyze results in a theoretically driven manner. To overcome these limitations in the field, the overarching goal of this Research Program proposal is to examine trajectories of media use - characterizing the context, content, and problematic uses of media - in a diverse group of 1200 children aged between 1 to 7 years, assessing temporal associations with emotion regulation and social competence using a cohort sequential design. The Research Program includes three longitudinal studies, collecting data in three cohorts that span the entire age range (1- 3, 3-5, 5-7 year olds). New data collected during the project period will be compared to data collected before and during the COVID pandemic using the same toolkit to examine how the pandemic altered media exposure patterns and the relation between media exposure and socio-emotional outcomes. The work described in this application will also produce research infrastructure to increase the efficiency of coding the quality of media content, a bottleneck in the field. Finally, the data will be integrated, shared, visualized and analyzed in a shared analytic research hub. The proposed research is significant because it would be the first synergistic effort to utilize a comprehensive assessment of the family media ecology in a large, diverse, longitudinal sample to identify antecedents of problematic media use in early childhood as well as specific media use patterns that support social and emotional development in early childhood. The proposed work is innovative because it (1) uses a multi-method, comprehensive assessment of the family media ecology; (2) applies an ecological lens to study media effects and socio-emotional development within the family system; (3) maximizes impact and efficiency with synergistic science; (4) streamlines content coding in an ever-changing media environment; and (5) builds a collaborative platform for cleaning, integrating, and analyzing shared data for reuse.
