BSc [Hons] Applied Psychology

Hi, I am soon to be a graduate of BSc Applied Psychology from IADT. My academic interests lie in the intersection of Neuropsychology and Sport and Health Psychology, areas that have influenced my studies and research.

Project Description

This research project examined the relationship between smartphone screen time and daytime sleepiness among Irish university students. Focusing on a demographic heavily integrated with digital technology, the study employed the Epworth Sleepiness Scale (ESS) and iOS Screen Time data to analyze how smartphone use impacts alertness and overall wellness during daytime hours. The project contributed to the ongoing discourse surrounding digital media's influence on sleep and cognitive functions.


Project Objectives

The objective of this study was to determine if a significant correlation exists between the amount of smartphone screen time and the level of daytime sleepiness among students. It aimed to clarify conflicting findings from previous research by focusing on a population that is extensively engaged with smartphones. Utilizing a cross-sectional observational design, the research provided insights into the immediate effects of smartphone usage on student health and academic performance.


Project Outcomes

Contrary to initial hypotheses, the findings of the study indicated a non-significant negative correlation between smartphone screen time and daytime sleepiness. This result suggests that increased screen time does not necessarily correspond with higher levels of daytime sleepiness. These findings challenge some prevailing assumptions and align with recent studies that question the direct impact of screen time on sleep quality. Highlighting the complexity of digital behaviors and their varied effects on individuals, the study underscores the necessity for further research using more robust and diverse methodologies.
