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

Project summary Progress in understanding the effects of media exposure on child outcomes has 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. The overarching goal of this P01 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 1 to 7 years and examining temporal associations with emotion regulation and social competence using a cohort sequential design. The admin core will collate and integrate the Comprehensive Assessment of Family Media Exposure (CAFE) Toolkit data along with emotion regulation and social competence outcome data across the three studies. The CAFE Toolkit measures household media use through a web-based questionnaire, time-use diary, and passive-sensing app installed on family mobile devices (Barr et al., 2020; Radesky et al., 2020b). The administrative core will manage the data integration of the three longitudinal studies across the entire age range (1-3, 3-5, 5-7 year olds). Data collected from new cohorts will be compared to data collected before and during the COVID pandemic by the same research groups using the same CAFE Toolkit to examine how media exposure patterns varied as a function of the pandemic and how those experiences are related to socio- emotional outcomes. The P01 will also develop methods 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. 1
