## Abstract

Admin Core 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 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). 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.
