Sleep quality is defined as ideal sleep according to an individual's need. The quality of sleep influences the physical and mental health of teenagers. Despite several studies on the effects of smartphone use, there is a paucity of research particularly addressing the correlation between the intensity of smartphone use and sleep quality in high school teenagers. This study aims to analyze the relationship between smartphone use and sleep quality in adolescents at SMAN 2 Sukoharjo. “The study strategy used is descriptive correlational using a cross-sectional approach, performed in November 2024 at SMAN 2 Sukoharjo. The sample included 100 students, chosen by a simple random sampling method employing the Slovin formula. The use of smartphones was assessed by a validated and reliable questionnaire, while sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The Spearman rank test was used for correlation analysis, revealing a significant association between smartphone usage and sleep quality among teenagers at SMAN 2 Sukoharjo (r = 0.512; p = 0.001), showing a moderately strong positive correlation. This research concludes that increased smartphone use correlates with poorer sleep quality in teenagers. teenagers and parents need education on the significance of time management and self-regulation in smartphone use to preserve teenagers' sleep quality. Further studies are encouraged to investigate the correlation between smartphone use and sleep quality in teens using a qualitative methodology.]]>
