Psychological symptoms were assessed using the Generalized Anxiety Disorder-7 items and Patient Health Questionnaire-9 items. Effects of screen time on sleep was evaluated using the Insomnia Severity Index and Bedtime Procrastination Scale.Results Female students reported higher depression (p = 0.018) and anxiety (p = 0.023) than male students; however, there was no difference in their sleep. Insomnia, depression, and anxiety were highest among phone users. A screen time of more than 7 hours per day was significantly associated with higher depression (67.9%), anxiety (61.6%), insomnia (82.1%), and bedtime procrastination. It also indicated a shift toward a less healthy diet and light exercise.Conclusions Seven hours of screen was found to develop depression and anxiety, exercising less, eating a less healthy diet, and experiencing disturbed sleep among school adolescents.
