Blue screen blue mood: investigating the association of daily screen time with sleep quality and mental distress in students

Abstract

Introduction: The pervasive influence of technology on daily life, particularly through screens, and its implications for sleep quality and mental health is critical.

Objective(s): To evaluate the daily screen time of students from different fields of study and to assess its association with demographic variables as well as sleep quality and mental health symptoms.

Materials & Methods: This Cross-sectional study was conducted in Isra University, Hyderabad from August 2023 to February 2024. A total of 152 participants were included in the study. Data regarding demographic details, sleep quality, mental distress, and daily screen time was collected after informed consent. Statistical analysis, conducted using SPSS (version 22), determined correlations between daily screen time, PSQI, and DAS scores (p≤0.05, 95% confidence).

Results: The mean age of the participants was 20.59±2.16 years. The vast majority of participants belonged to urban areas (87.5%) and were day scholars (74.34%). The mean daily screen time of the study participants was found to be 5.85±1.14 hours. The mean scores of depression, anxiety, stress, and PSQI were found to be 13.34±12.01, 11.17±9.41, 15.32±11.09, and 6.45±3.48 respectively. There was a statistically significant positive correlation observed between screen time and depression (r = 0.81, p<0.01), anxiety (r = 0.78, p<0.01), stress (r = 0.83, p<0.01), and PSQI (r = 0.75, p<0.01).

Conclusion: Increased screen time was associated with poorer sleep quality and higher levels of mental distress.
