HUBUNGAN SMARTPHONE ADDICTIONS DENGAN KUALITAS TIDUR DAN ACADEMIC PERFORMANCE PADA MAHASISWA ILMU KEPERAWATAN UNIVERSITAS MUHAMMADIYAH MALANG

Background: The increasingly frequent use of smartphones among university students provided various benefits but also led to negative consequences. One of these was smartphone addiction, defined as excessive smartphone use that interfered with daily activities. This condition could reduce sleep quality due to exposure to blue light from smartphone screens and potentially affect students’ academic performance. This study aimed to determine the relationship between smartphone addiction, sleep quality, and academic performance among university students.
Methods: his study employed an observational analytic design with a cross-sectional approach. The study population consisted of students from the Nursing Science Program at Universitas Muhammadiyah Malang. The sample was selected using proportional stratified random sampling. Data were collected using the Smartphone Addiction Scale–Short Version (SAS-SV), the Pittsburgh Sleep Quality Index (PSQI), and Grade Point Average (GPA). Data analysis was conducted using univariate and bivariate analyses.
Results: The results showed that most students experienced smartphone addiction and had poor sleep quality. Bivariate analysis indicated a significant relationship between smartphone addiction and sleep quality, with a weak negative correlation (r = -0.242; p = 0.001). Meanwhile, the relationship between smartphone addiction and academic performance showed a very weak negative correlation (r = -0.122) and was not statistically significant (p = 0.059).
Conclusion: It was concluded that smartphone addiction was associated with decreased sleep quality among students but was not proven to affect academic performance. Therefore, educational efforts and interventions were needed to control smartphone use in order to improve sleep quality and support students’ health.
