Honors Thesis


College students represent a vulnerable demographic of sleep and mental health disturbances. Prior research on the impact these pervasive struggles have on academic performance in college student populations has yielded mixed findings and has largely been limited to the exclusive use of subjective sleep measures. The present study investigates the impact of sleep efficiency, subjective sleep quality, and mental health on the academic performance of college students. In this study, a sample of undergraduate students (N =92) wore a Fitbit actigraphy monitoring device for 21 days and completed a battery of self-report questionnaires assessing sleep quality and mental health, including the Pittsburgh Sleep Quality Index, the State-Trait Anxiety Inventory, and the Center for Epidemiologic Studies Depression Scale-Revised. Cumulative GPAs were collected from the participants who provided their consent. It was hypothesized that sleep efficiency and subjective sleep quality would mediate the relationship between mental health and GPAs. Results revealed no significant mediation effects of sleep efficiency and subjective sleep quality on mental health and GPAs. These findings suggest that while sleep and mental health are important factors for college students, they may not have a direct impact on academic outcomes.
