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

项目概要 数字媒体访问的快速增长伴随着对复杂、实时的研究的缺乏。 家庭媒体背景和社会认知结果，部分原因是缺乏全面的衡量 工具。为了应对这一挑战，PI 的跨学科研究团队开发了一种多方法、可扩展、 具有成本效益的工具包称为家庭媒体接触综合评估 (CAFE) 工具包。的 工具包旨在捕获早期媒体曝光的内容和背景（Barr 等人，2020；Radesky 等人） 等人，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， 由于缺乏了解媒体曝光对儿童结局的影响，理解媒体曝光对儿童结局的影响的进展也受到限制。 大型且具有代表性的纵向数据集，在不断变化的情况下跟踪内容质量的难度 媒体环境，缺乏在理论驱动下快速共享和分析结果的机制 方式。为了克服该领域的这些限制，本研究计划的总体目标 提议是检查媒体使用的轨迹——描述背景、内容和问题 媒体的使用——在 1200 名 1 至 7 岁儿童的不同群体中，评估时间 使用队列序贯设计与情绪调节和社交能力相关。研究 该计划包括三项纵向研究，收集跨越整个年龄范围（1- 3、3-5、5-7 岁）。项目期间收集的新数据将与之前收集的数据进行比较 在新冠病毒大流行期间，使用相同的工具包来检查大流行如何改变媒体曝光 模式以及媒体曝光与社会情感结果之间的关系。本文所描述的工作 应用程序还将产生研究基础设施，以提高编码媒体质量的效率 内容，成为该领域的瓶颈。最后，数据将被集成、共享、可视化和分析 共享分析研究中心。拟议的研究意义重大，因为这将是第一个协同作用 努力对家庭媒体生态进行全面评估，进行大规模、多样化、纵向的研究。 样本以确定幼儿时期有问题的媒体使用的前因以及特定的媒体使用 支持幼儿期社交和情感发展的模式。拟议的工作具有创新性 因为它（1）采用了多方法、全面的评估家庭媒体生态； (2) 应用 生态视角研究家庭系统内的媒体影响和社会情感发展； (3) 通过协同科学最大限度地提高影响力和效率； (4)在不断变化的情况下简化内容编码 媒体环境； (5) 构建共享数据清理、整合和分析的协作平台 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.
