Social restrictions such as school closures, imposed worldwide because of the ongoing COVID-19 pandemic, may increase exposure to gaming and lead to addictive gaming behavior in young people. In this study, we investigated gaming behaviors among Japanese students during COVID-19 school closures. Methods: Students completed questionnaires regarding their living conditions, game-related behaviors, diagnosis of Internet addiction, psychological difficulties, and the impact of the COVID-19 pandemic. We compared differences between the responses of potentially at risk for gaming disorder (potentially at risk for gaming disorder; defined in this paper with reference to the ICD-11 MMS criteria for gaming disorder [PGD]) students who met the criteria for a diagnosis of gaming disorder in ICD-11 MMS and those of control students. Logistic regression analysis was performed to predict the extent of factors contributing to potential gaming disorder. Results: Four thousand and forty-eight participants completed the survey. Compared with control students (93%), potentially at risk for gaming disorder (defined in this paper with reference to the ICD-11 MMS criteria for gaming disorder, PGD) students (7%) reported playing games for longer times, spending more money on in-game purchases, were of younger age at the start of game playing, showed a tendency toward Internet dependence, practised school avoidance or absenteeism, and demonstrated the need for psychological support. Moreover, participants in the PGD group reported more anxiety about COVID-19 than control participants, as well as an increase in game-playing time and amount of money spent on games during the COVID-19 pandemic. Conclusion: These results indicate that young people classified as having a gaming disorder not only exhibit characteristic game-related behaviors but may be psychologically and socially vulnerable and need special support, especially during the ongoing COVID-19 pandemic., 長崎大学学位論文 学位記番号:博(医歯薬)甲第1565号 学位授与年月日:令和6年3月19日, Author: Naoki Yamamoto, Yoshiro Morimoto, Hirohisa Kinoshita, Hirokazu Kumazaki, Sumihisa Honda, Ryoichiro Iwanaga, Akira Imamura, Hiroki Ozawa, Citation: Psychiatry and Clinical Neurosciences Reports, 1(3), art. no. e37; 2022, Nagasaki University (長崎大学), 博士(医学) (2024-03-19)},
