THE EFFECTS OF SMARTPHONE ADDICTION, STRESS, AND BEDTIME PROCRASTINATION ON SLEEP QUALITY

The present investigation explores the complex interconnections that exist among university students regarding smartphone addiction, depression, anxiety, stress, bedtime procrastination, and sleep quality. A range of psychological assessments were utilized on a sample of 547 college students. These assessments included the Pittsburgh Sleep Quality Index, the Smartphone Addiction Scale, the Depression, Anxiety, and Stress Scale-21, and the Bedtime Procrastination Scale. The findings suggest that there are noteworthy correlations among psychological distress, sleep quality, smartphone addiction, and bedtime procrastination. It is worth mentioning that anxiety, stress, and procrastination before bedtime emerged as substantial predictors of sleep quality. Conversely, depression and smartphone addiction did not demonstrate any significant effects. Consistent with prior research, these results indicate a robust correlation among psychological distress, delayed bedtime preparation, and substandard sleep quality. Nevertheless, discrepancies in results concerning the influence of depression on sleep quality and smartphone addiction underscore the necessity for additional investigation, specifically utilizing longitudinal designs and encompassing diverse populations. Notwithstanding constraints including sample homogeneity and reliance on self-report measures, this research highlights the criticality of interventions that specifically address anxiety, stress, and bedtime procrastination in order to enhance the quality of sleep among college students.
