Abstract: Objective To understand the relationship between internet gaming disorder（IGD） and emotional problems among 2022 freshmen at Tianjin Public Security Profession College,and to expand the application of the Chinese version of the ten-item internet gaming disorder test（IGDT-10） in China. Methods In October 2022,a cluster sampling method was used to select the 2022 freshmen of Tianjin Public Security Profession College as the study subjects. The Chinese version of IGDT-10 and the Chinese version of depression anxiety stress scale（DASS-21） were administered to 987 students. Network analysis was employed to construct and analyze the network relationship model among factors. Results The prevalence of IGD was 15.00%. In the high-risk group,the weight between "giving up activities" and "negative consequences 1",as well as between "persistent use" and "negative consequences 2",was the highest（both 0.52）. In the low-risk group,the weight between "preoccupation" and "escape" was higher（0.32）. "Loss of control" had the highest centrality indicator in the high-risk group. Depression（r=0.57）,anxiety（r=0.51）,and stress（r=0.48） were all significantly positively correlated with IGD（all P<0.01）. Conclusion The cutoff criteria for IGD supported by the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition（DSM-5）,are more conservative compared to the latent profile analysis method. It is suggested that interventions for college students with IGD should focus more on self-control and the restoration of interpersonal relationships.
