Internet gaming addiction (IGA), depression, and anxiety are significant issues among children and adolescents, with substantial social implications. Understanding the specific characteristics of this relationship is crucial for developing effective prevention and intervention strategies. The present study employed network analysis to explore the symptom network of IGA, depression, and anxiety among 1,548 Chinese children and adolescents. The results showed that the core symptoms of IGA among children and adolescents were “tolerance”, “withdrawal”, and “conflict”. There was no significant gender difference in the structure, global strength, and core symptoms of IGA. Although there were no significant differences in the structure of the symptom network of IGA among children and adolescents of different ages, there were significant differences in global strength and some core symptoms (“conflict”). The core symptoms of the comorbidity of IGA, depression, and anxiety in children and adolescents included “feeling downhearted and blue”, “breathing difficulty”, “difficult to work up the initiative to do things”, and “withdrawal”. The comorbidity network did not show significant gender and age differences in network structure, but there were significant gender differences in global strength. Furthermore, there were significant gender and age differences in some core symptoms. The social impact of these findings is profound, highlighting the need for targeted interventions in schools and communities to address IGA and its comorbidities. Our results also suggest that interventions should be tailored to consider gender and age differences to maximize effectiveness.

Recently, internet gaming addiction and suicide have been global public health issues among adolescents. This study used convenience sampling and surveyed 1906 Chinese adolescents to investigate the relationship between internet gaming addiction and suicidal ideation and the role of negative emotion and hope in the relationship between the two. The results showed that the detection rate of internet gaming addiction among adolescents was 17.16% and the detection rate of suicidal ideation was 16.37%. Moreover, there was a significant positive correlation between internet gaming addiction and suicidal ideation. Negative emotion partially mediated the relationship between internet gaming addiction and suicidal ideation. In addition, hope moderated the relationship between negative emotion and suicidal ideation. The effect of negative emotion on suicidal ideation decreased as hope increased. These findings suggest that the role of emotion and hope in coping with adolescent internet gaming addiction and suicidal ideation should be emphasized.

Many studies have explored the relationship between metacognition and academic achievement in mathematics, but the results vary. In this study, meta-analysis was used to explore this relationship between metacognition and academic achievement in mathematics and influencing factors. According to the literature search, a total of 147 studies (1986-2024) and 338 independent samples met the inclusion criteria (n = 698,096). The results revealed metacognition was significantly positively correlated with academic achievement in mathematics, r = 0.32, 95 % CI [0.30, 0.34], Z = 28.49. Moreover, the moderating effects of age, domain, and culture were significant (p < 0.01). In conclusion, Metacognition is closely associated with academic achievement in mathematics but also that age, domain, and culture have a considerable impact on their relationship. More specifically, the degree of correlation between metacognition and academic achievement in mathematics was on the rise from preschool to high school, while it was lower in college. Compared with general field metacognition, mathematical metacognition is more closely linked to mathematics academic achievement. Lastly, compared with British and American countries, Chinese metacognition was more closely related to academic achievement in mathematics.
