Exploring Screen Time and Its Effects on Children's Mental Health: A Cross-Sectional Study

Background The increasing prevalence of screen-based activities among children has raised concerns about potential mental health effects. This study investigates the relationship between screen time and mental health outcomes in children aged 6 to 14 years in Saudi Arabia and Bahrain, focusing on emotional symptoms, conduct problems, hyperactivity, peer problems, and depressive symptoms. Methods A cross-sectional study was conducted with 670 children recruited through stratified random sampling. Data were collected using self-reported questionnaires and parental surveys from January to June 2024. Screen time was assessed across four activities: TV viewing, smartphone usage, computer/tablet use, and video game playing, recorded separately for weekdays and weekends. Mental health was evaluated using the Strengths and Difficulties Questionnaire (SDQ) and the Children's Depression Inventory (CDI). Descriptive statistics and Pearson correlation coefficients were used to analyze the data. Results Participants reported a mean total screen time of 7.25 ± 2.4 hours on weekdays and 8.4 ± 2.65 hours on weekends. Smartphone usage (2.75 ± 1.3 hours/day) was the most common activity. Emotional symptoms, conduct problems and depressive symptoms were significantly correlated with both weekday and weekend total screen time (weekday r = 0.43, r = 0.31, and r = 0.49, respectively, p < 0.001; weekend r = 0.47, r = 0.33, and r = 0.54, respectively, p < 0.001). Smartphone usage had the strongest association with depressive symptoms (r = 0.46, p < 0.001). Conclusion This study identifies a significant positive correlation between increased screen time and adverse mental health outcomes in children, particularly emotional symptoms and depressive symptoms. The findings emphasize the need for public health strategies to manage screen time and promote healthier digital habits to mitigate the potential negative effects on children's mental health.
