Social Media Addiction Dimensions, Sleep Disturbances, and Cumulative GPA Among Undergraduate Students: A Cross-sectional Study

To examine the relationships among social media addiction, sleep quality, and academic performance in university students. This cross-sectional study included 199 university students. Data were collected using a sociodemographic questionnaire, the Social Media Addiction Scale (SMAS), the Pittsburgh Sleep Quality Index (PSQI), and cumulative grade point average (GPA) verified from official academic transcripts. Pearson correlation and multiple linear regression analyses were performed. Most participants (61.8%) used social media for 3–5 hours daily. Total social media addiction was not associated with global sleep quality or cumulative GPA (p >.05). Sleep disturbance was negatively correlated with cumulative GPA (r = −.20, p =.004) and remained independently associated with cumulative GPA in the multivariable analysis (β = −.166, p =.015). Interference with daily life/loss of control was also negatively associated with cumulative GPA (β = −.295, p =.005), whereas deprivation showed a positive adjusted association (β =.247, p =.019). Female students had significantly higher GPAs than male students (p <.001). Sleep disturbance and impaired behavioral control, rather than overall social media addiction, were associated with lower cumulative GPA. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2026.
