The Impact of Sleep Quality on Academic Performance in Undergraduate Students: Examining the Roles of Sleep Duration, Sleep Quality, Sleep Efficiency and Sleep Difficulty

Abstract

Dreams serve important functions in student school performance that affects concentration, decision-making and cognitive efficiency. This study investigated the predictive relationship between sleep quality, sleep duration, sleep efficiency, and sleep disorders in academic achievement. Of the 501 students, anti-interrogation was conducted using the Pittsburgh Sleep Quality Index and GPA self-assessment. After excluding people who consumed sleep-related drugs, the final sample included 469 participants. Descriptive analyses were shown by a mean mean score of 3.15 (and = 0.53). Correlation results show that lower sleep, length of sleep duration, and the quality of major sleep disorders are significantly associated with lower GPA. Sleep does not show any important links. Simple linear regression confirms that sleep quality (β=-.119, p=0.009), sleep duration (β=-100, p=0.028), sleep disorders (β=-.098, p=0.031) are negative predictors of GPA. In the multiple regression model, only sleep duration remained a significant predictor (β=-096, p=0.044) after demographic control. Gender and academic years also had a significant impact on average scores, with students and students working better in subsequent semesters.
