Objective To explore the effect of family game intervention on reducing screen exposure and improving problem behaviors in early school-age children. Methods A total of 138 early school-age children with screen exposure exceeding 1 hour per day were randomly divided into 2 groups of 69 cases each. The control group received routine health education, while the experimental group received both routine health education and an 8-week family game intervention. The Screen Exposure Time Questionnaire, the Caregiver Monitoring of Children′s Electronic Device Use Questionnaire, and the Achenbach Child Behavior Checklist were used to assess the intervention effects before and after the intervention.Results A total of 67 children from both the experimental and control groups completed the study. After the intervention, the parental monitoring score of electronic device use in the experimental group was significantly higher than that in the control group (P<0.05), and the screen exposure time of the children in the experimental group was significantly lower than that in the control group (all P<0.05). However, there was no significant difference in the total problem behavior scores between the two groups (P>0.05). Conclusion Family game intervention can enhance parental monitoring of early school-age children′s use of electronic devices, reduce screen exposure time, and improve problem behaviors in children.
