Many studies have explored the association between adverse childhood experiences (ACEs) and Internet addiction (IA), yet the research findings on the association between them are inconclusive. We conducted a systematic search on 7 databases to identify the relevant studies published until January 2023, and analyzed the findings from 37 studies across 12 countries involving 45,364 participants aged 8 to 67 years (51 % women). Results indicated a positive correlation (r = 0.21) was found between ACE and IA around the world, which differed among continents. It was found that all ACE subtypes were significantly associated with IA (range r = 0.16 to 0.25). Meta-regression showed a stronger association among younger individuals without moderating effects of gender or publication year. In conclusion, this study sheds light on the significant association between ACEs and IA, emphasizing the need for targeted interventions and preventive measures. Future research could delve into specific interventions aimed at mitigating the impact of ACEs on IA, such as cognitive-behavioral therapies or metacognitive therapy interventions. Additionally, investigating cultural factors that may influence this association could provide valuable insights into tailored approaches for different populations. Understanding these dynamics is crucial for developing effective strategies to address IA and its underlying factors.
