Abstract Mental disorders represent 45% of the global disease burden among children and adolescents aged 10-24 years old. It is crucial to develop effective interventions that can be integrated into daily school activities in order to provide convenient and accessible mental health services for students and faculty members. The study conducts a randomized controlled trial to examine universal mental health promotion among children. The current protocol aims to develop a universal resilience focused program, which focuses on emotional regulation, coping, and problem solving. A total of 20 classes from two primary schools in grades 4-5 in Anhui, Tianchang were randomly assigned to either the intervention or waitlist group. This training consisted of 14 weekly 40 minute sessions of manualized interventions that were compatible with regular curricular activities. It is expected that this current intervention will enhance the psychological resilience of children and evaluate the effectiveness of promoting mental health among children followed up on indicators of depressive and anxiety symptoms, psychological resilience, oppositional defiant and conduct problems by questionnaires at baseline and after the intervention.

A survey of 12 experts from 6 different provinces, cities and regions in China was conducted, and the Delphi technique was used to collect and analyze expert opinions data about the importance and feasibility of questionnaire content. The dimensions and specific items of the questionnaire were finally determinded. Results: The response rates were 100% in both rounds of Delphi consultation. Kendall coordination degree W =0.22 ( χ 2=63.72, P <0.01), which showed the agreement of expert opinions. The initial scale consisted of 4 dimensions and 17 items, including parental cognition of school based depression screening, parental cognition of school depression screening results feedback and management, parental attitude of school based depression screening, parental utilization of mental health services.

Objective: To explore the association between exposure to bedroom night light during sleep and emotional symptoms in children and provide a scientific basis for subsequent effective prevention and intervention. Methods: In December 2021, 1 926 students from grades 4 to 6 were recruited to conduct a student questionnaire survey in two primary schools in Tianchang of Chuzhou City, Anhui Province. The data, including general demographic information, use of night lights and curtains, emotional symptoms, and other information, was collected. Binary Logistic regression analysis was used to examine the correlation between night light use and children s emotional symptoms. Results: The reporting rates of depression symptoms, generalized anxiety symptoms, social phobia, and obsessive compulsive symptoms of the children were 2.5%, 2.6%, 3.4% and 2.5%, respectively. About 12.6% of children often sleep with a night light on, and 22.0% of children did not close the curtains. Binary Logistic regression analysis revealed that frequent sleep with night lights was associated with an increased risk of depression symptoms( OR=2.29, 95%CI = 1.04- 5.03), social phobia ( OR=1.93, 95%CI =1.02-3.64) and obsessivecompulsive symptoms ( OR=3.44, 95%CI =1.72-6.88) in children( P < 0.05). Conclusion There is a positive correlation between bedroom night light exposure during sleep and the detection rate of children s emotional symptoms. The attention should be paid to bedroom light environment of children during sleep to reduce the adverse effects of night light exposure on the mental health.
