Summary

Technology use has been growing 10-20% a year for the past two decades and exceeded 40% during the COVID-19 lockdown (Sherer et al., 2022). Since then, the dependency on electronics, especially mobile devices, has continued to increase among young adults (Madigan et al, 2022). A cross-sectional study was conducted in fall 2025 with undergraduate students at Belmont University. Using a simple random sample, participants completed a 34 item survey that inquired about their phone and sleep habits. Descriptive analysis was performed in Excel. The final sample size of 20 students found that 78% of students exceed a daily screen time use of 5 hours on their smartphones. Nearly 40% of Belmont students fail to meet deadlines in class due to excessive phone use. Research shows that daily screen time use that exceeds 5 hours can lead to cognitive inhibitions (Descourouez, 2024). The results of this study could inform future programming to help undergraduate students decrease screen time and dependency on mobile devices.
