Sleeping on Success: How Sleep Quality Shapes the Psychological Well-Being of Malaysian Undergraduates

Abstract

This study examines the relationship between sleep quality and psychological well-being among 110 Malaysian undergraduate students recruited through convenience sampling. Utilizing a self-reported questionnaire, sleep quality was assessed through the Pittsburgh Sleep Quality Index (PSQI), while the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) measured psychological well-being. Pearson correlation and independent sample t-tests were conducted to analyze the data. Results indicate a weak negative correlation between sleep quality and psychological well-being (r = -0.318, p < 0.001), suggesting that poor sleep quality is associated with reduced well-being. No significant differences were observed in sleep quality between on-campus and off-campus students (p = 0.298); however, students living on-campus reported significantly higher psychological well-being (p = 0.015). These findings highlight the need for targeted interventions, such as class schedule adjustments, to enhance overall student well-being in Malaysian higher education settings.
