Academic Procrastination, Smartphone Addiction, Sleep QualityAbstract
Purpose of this study is to determine how the sleep quality of early adult students in East Java is related to academic procrastination and smartphone addiction. This study uses a quantitative research approach with a correlational method, and sampling was conducted using purposive sampling techniques involving 272 students in the East Java region. Scales used include Academic Procrastination Scale (r = 0.835), Smartphone Addiction Scale (r = 0.931), and Sleep Quality Scale (r = 0.836). Analysis was performed using multiple linear regression with SPSS. The results showed negative correlation between academic delay and sleep quality (B = –0.468; p < 0.05) and between smartphone addiction and sleep quality (B = –0.327; p < 0.05). Simultaneously, students' sleep quality was significantly correlated with both independent variables with a contribution of 51.2% (R² = 0.512) indicating that students' sleep quality decreased as the level of academic procrastination and smartphone addiction increased.
