What this research studies
This research investigates the impact of digital media use on preschoolers aged 3-5 years, focusing on how screen time influences their sleep, physical activity, and social-emotional health. By employing advanced techniques like ecological momentary assessment and accelerometry, the study aims to objectively measure the timing, content, and duration of screen use in real-time. This approach will help identify the unique ways in which digital media habits affect children's overall well-being and development. The findings could provide valuable insights for parents and caregivers on managing screen time effectively.
