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 disturbance in academic achievement. Of the 501 students, data were collected 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 score of 3.15 (and S.D= 0.53). Correlation results show that lower sleep quality, longer sleep duration, and sleep disturbance are significantly associated with lower GPA. Simple linear regression confirms that sleep quality (β=-.119, p=0.009), sleep duration (β=-.100, p=0.028), sleep disturbance (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 female students and students working better in last semesters.
