With the inclusion of Internet gaming disorder (IGD) in both the DSM-5 and ICD-11, understanding the prevalence and diagnostic discrepancies is crucial for developing appropriate interventions. This study presents a meta-analysis of the prevalence of IGD based on two diagnostic criteria. We systematically searched the PubMed and Web of Science databases. A total of 22 studies were included in the final analysis. The analysis incorporated studies employing the DSM-5 and ICD-11 criteria and focused on the impact of various factors, including study location, sample characteristics, sample size, and quality score, on the reported prevalence rates using a random-effects model. The pooled prevalence of IGD is 6.7% (95% CI: 5.7–7.7%). The subgroup analysis indicated significant differences in the prevalence rates of IGD (DSM-5 criteria) and GD (ICD-11 criteria) (Q b = 38.46, p < 0.01). There were also significant differences in IGD prevalence rates between different scales (Q b = 54.23, p < 0.001). Our findings indicate that different diagnostic criteria and different assessment scales have a significant impact on the prevalence of IGD. This underscores the importance of adopting standardized methodologies to guide public health interventions. However, given the limited research based on ICD-11 diagnostic criteria, further investigation is necessary to determine the variations in prevalence rates of IGD under different diagnostic standards.

The object of this study is to examine the effects of a short-term intensive-type Cognitive Behavioral Therapy (CBT) intervention to prevent internet addiction among Chinese college students. We conducted a randomized controlled trial applying a group counseling intervention program based on CBT. Data included 21 participants in the intervention group and 22 participants in the control group. The results showed that the intervention program reduced college students’ internet addiction symptoms and procrastination and improved their sense of coherence. Regarding the sustained effect, internet addiction symptoms decreased and perceived social support from significant others improved in college students. However, the intervention program did not significantly reduce their average daily internet use time and psychological stress. Overall, this study developed a short-term intensive-type intervention program based on CBT theory, which is complementary for Chinese college students with internet addiction.

Introduction: This study aimed to explore the relationships between problematic social networking site use (PSNSU), Internet Gaming Disorder (IGD), internet use motives, and self-control among university students in China and Japan. Specifically, it investigated the indirect effects of self-control on IGD and PSNSU through various internet use motives, considering gender differences.Methods: A sample of 697 university students (465 females; 397 Chinese) was surveyed. Path analysis was conducted separately for male and female users to examine the relationships between self-control, internet use motives, IGD, and PSNSU.Results: The results indicated that self-control had significant indirect effects on IGD through enhancement (β = 0.096**, p = 0.005), social (β = -0.090**, p = 0.007), and conformity (β = -0.117**, p = 0.001) motives, but these effects were observed only in the male group. Self-control also exhibited indirect effects on PSNSU through enhancement, social, coping, and conformity motives, with a greater impact observed on PSNSU than on IGD. Gender differences in mediating effects were identified, with males and females showing distinct patterns.Discussion: The findings highlight the importance of understanding gender differences and motivational factors in problematic internet use. These insights contribute to a better understanding of how internet use motives influence IGD and PSNSU in different contexts.

With the inclusion of Internet Gaming Disorder (IGD) in both the DSM-5 and ICD-11, understanding the prevalence and diagnostic discrepancies is crucial for developing appropriate interventions. This study presents a meta-analysis of the prevalence of IGD based on two diagnostic criteria. We systematically searched PubMed, Web of Science databases. 17 studies were included in the final analysis, The analysis incorporated studies employing the DSM-5 and ICD-11 criteria and focused on the impact of various factors, including study location, sample size, and quality score, on the reported prevalence rates using a random-effects model. Heterogeneity and publication bias were analyzed using an I2 test and Galbraith plots , The prevalence of IGD varied among the selected studies, with a general pooled prevalence of 5% (95% CI: 3%–7%). Subgroup analysis indicated that the prevalence rates of IGD (DSM-5 criteria) and GD (ICD-11 criteria) do not show significant differences. DSM-5-based scales yielded varied results, while heterogeneity among the studies was high (I2 = 98.50). In contrast, ICD-11-based scales produced more consistent and less variable findings. Our findings highlight that assessment scales, not diagnostic criteria, impact IGD prevalence. This underscores the importance of adopting standardized methodologies to guide public health interventions. However, given the limited research based on ICD-11 diagnostic criteria, further investigation is necessary to determine the variations in prevalence rates of IGD under different diagnostic standards.

Introduction: Game escape motivation has been associated with internet gaming disorder (IGD) in previous research, but its role in family-linked associations remains unclear. Methods: In a cross-sectional survey of Chinese senior-high-school students (n = 145) and university students (n = 285), we estimated parallel indirect-association models linking parental warmth to scores on an 11-item study-specific gaming-related symptom index through escape motivation, self-control, and emotional distress. The index was substantially adapted from the Gaming Disorder Scale for Adolescents (GADIS-A) and has not undergone independent validation. Results: Emotional distress statistically accounted for part of the association between parental warmth and index scores in both groups, and an indirect association through self-control was detected in the senior-high-school group. Escape motivation showed positive adjusted coefficients, but no indirect association through escape motivation was detected in either group. Discussion: These findings concern scores on an unvalidated study-specific measure, not established IGD symptom severity. The cross-sectional design does not establish temporal mechanisms or developmental differences.
