This systematic review explores preventive interventions for internet addiction in young children under 12 years old. The study aimed to identify effective interventions and future directions for preventing or reducing the risks of internet addiction in this vulnerable population. A total of 14 primary studies were included, which were categorized into four approaches: children's education, parenting strategy, strategic physical activity, and counseling. Ten interventions showed promising efficacy in reducing internet addiction risks with small-to-medium effect sizes. Interventions that enhanced children's digital literacy and healthy online behavior were more effective than those that forced children to reduce screen time. Interventions that shifted children's focus from online activities to real-world activities also showed promise in reducing internet engagement and preventing addictive behavior. The study identified strengths and limitations of each approach, which are valuable for developing future interventions. The findings suggest the need for sustainable and accessible interventions to educate healthy internet users, provide appropriate parenting strategies, and suggest substitution activities to reduce online activities. The use of digital tools and the involvement of children's stakeholders are encouraged to improve the capability, efficiency, and accessibility of the intervention. Future studies should consider the appropriateness of the intervention with family conditions and provide adequate training to implement the intervention as intended. Product developers and policymakers can also contribute by developing product design guidelines to minimize internet addiction risks. The study highlights the importance of parents in preventing internet addiction in young children. However, some parenting strategy interventions were not effective, possibly due to inappropriate strategies or parents' failure to implement the intervention as intended. The study also emphasizes the role of children's environment, including family and peers, in influencing internet addiction risks. Interventions that involve multiple stakeholders, such as parents, teachers, and health practitioners, are recommended to reinforce positive online behavior and prevent negative influence. The study found that most interventions were temporary programs with limited sessions and accessibility. Sustainable interventions may be needed to improve long-term effects in young children. Additionally, interventions that require significant resources or expert involvement, such as counseling, may not always be accessible in low-resource regions. Therefore, developing interventions with better accessibility is recommended to reach various families with different backgrounds. Combining multiple approaches may improve efficacy in overcoming the limitations of each approach. For example, an integrated intervention could facilitate families in educating healthy internet use, determining appropriate internet use regulations, and suggesting attractive physical activities to prevent their children from over-engagement with online activities. Digital technology can be beneficial in achieving these goals by increasing the capability, efficiency, and accessibility of the intervention in encouraging children to have healthy online behavior. The study also highlights the need for future research to investigate how product developers can contribute to preventing addictive behavior in their users. Additionally, there is a lack of intervention studies intended for children under eight years old, which is crucial to ensure children do not develop addictive behavior in early childhood. The study acknowledges the limitations of its findings, including the conceptualization of internet addiction and the regional focus of the studies.
