Purpose: The purpose of this study was to investigate the relationship between the risk of school bullying victimization and the risk of Internet gaming disorder according to gender in adolescents. Methods: The data of 1,920 middle school students collected at the baseline of the Internet user Cohort for Unbiased Recognition of gaming disorder in Early Adolescence (iCURE) study were analyzed. For statistical analysis, $x^2$ test, t-test and stratified multiple logistic regression analysis were conducted using SAS 9.4. Results: The prevalence rate of Internet gaming disorder of middle school boys was greater than that of girls (Boys: 9.9%, Girls: 6.2%). The greater the risk of school bullying victimization, the greater both the risk of Internet gaming disorder and the average daily time spent on Internet gaming. In girls, the relationship between the experience of being bullied in school and Internet gaming disorder was not statistically significant. However, the boys who had been bullied in school were 3.2 times more vulnerable to the risk of Internet gaming disorder than those without such experience (95% CI: 1.135-8.779). Conclusions: When considering interventions for Internet gaming disorder for adolescents, bullying victimization should be taken into account as well. Particularly, relieving stress related to bullying victimization can be important for boys with Internet gaming disorder.

The purpose of this study is to find out the role of social support and self-esteem in the relationship between gaming disorder and suicidality of college students. A survey and analysis were conducted on 1,154 students in a four-year university in Gyeonggi-do of Korea. With analysis of the Internet Gaming disorder scale, 162 people (14%) were subjected to gaming disorder and 992 (86%) were non-gaming disorder. The hypothesis of this study was verified as follows. First, college students with gaming disorder have higher suicidality and lower social support and self-esteem than those with non-gaming disorder. Second, gaming disorder of college students have a positive correlation with suicidality, while gaming disorder will have a negative correlation with social support and self-esteem. Third, social support and self-esteem mediate the relationship between gaming disorder and suicidality of college students. These results show that social support and self-esteem can act as protective factors. The results are very meaningful in that they have verified the high risk of suicidality of college students with gaming disorder. It is suggested, when college students show signs of Internet gaming addiction, a more active prevention for suicidality should be considered as they can become a suicidal high risk group.

Objectives: Gaming disorder has been viewed as a disease in the DSM-5 and ICD-11. Its essential symptoms are loss of control over gaming, gaming becoming a markedly prioritized activity over other activities of daily living, and continued and excessive use of gaming despite negative problems occurring. Methods: Children and adolescents are especially vulnerable to gaming disorder because the striatal pathways related to reward develop earlier than the control regions of the prefrontal cortex. It is also associated with decreased dopamine D2 receptors. Addiction is related to 'want' and is explained by incentive-sensitization. In addition, allostasis, in which homeostasis is continuously achieved at a new target value, is also related to gaming disorder. In addition, personality causes, unchangeable factors, and external factors can influence on the onset of gaming disorder. Results: Prevention is the best solution for gaming disorder, and the role of parents is important. For gaming disorder, bupropion is used, cognitive-behavioral therapy and family-based therapy are also beneficial. Herbal medicine treatment such as Antler velvet and ginseng can be effective. Electroacupuncture and acupuncture using PC6, SP6, and LR3 has a correlation with relieving Internet craving. Ear-acupuncture was also effective in treating addiction. Conclusion: Psychologically, 'want' is an intense longing for reward and motivation, and is related to addiction. This 'want' may rather be related to avoidance, and game addiction in children and adolescents may be due to wanting to escape from academic stress or avoidance of comparison. Therefore, the importance of 'like', which gives pleasure in itself, increases. It can also be explained with Sasang Constitutional Medicine.

Objectives Internet gaming disorder (IGD) is associated with attention deficit/hyperactivity disorder (ADHD) or depression etc. We tried to examine the mediating effects of depression in the relationship between ADHD and IGD. Methods This study was conducted on 2000 people who participated in on-line survey among 14-39 year-old men and women in 2017. And we clarified the relationship among IGD, ADHD, and depression and tested the mediation model. The mean and standard deviation of the main variables were calculated and correlation analysis was performed to confirm the relationship among the main variables. In order to test the mediating effect of depression on the relationship between ADHD and IGD, the structural equation model was implemented using AMOS 21 (IBM). Results There were significant correlations among the variables; IGD, ADHD and depression. Depression had a mediating effect 0.23 (95% confidence interval : 0.17-0.28) in the relationship between IGD and ADHD. Conclusions This study showed that depression can mediate ADHD and IGD. Therefore, the evaluation and management of depression and ADHD should be included in the diagnosis and treatment of IGD.

Internet gaming disorder (IGD), one of the common subtypes of internet addiction, is now classified in Section 3 of DSM-5 and is increasingly regarded as a growing health concern in many parts of the world. Consequently, many psychotherapeutic and psychopharmacological approaches have been considered and some research regarding therapeutic strategies has been conducted. However, treatment of IGD is in its early stages and therefore is not yet well established. This article reviews multiple therapeutic modalities including our own treatment model for IGD according to clinical and biological effects, thus providing suggestions for standard treatment strategies. The two main streams are psychopharmacological treatment and cognitive-behavior treatment, and the cognitive-behavior approach includes cognitive reconstruction, psychoeducation, and parenting coach. Many other non-pharmacological treatments are also recommended for personalized treatment of IGD.

Due to the increasing use of the internet, various social problems have been emerging, and one of them is internet gaming disorder (IGD). The purpose of this study was to investigate whether low internal motivation was present in IGD and basic psychological needs affected internal motivation. Twenty-one individuals with IGD and 21 healthy controls performed a 'motivation task' in which the avatar in virtual reality asked whether they would accept an activity in two conditions stimulating intrinsic or extrinsic motivation. The task performance was compared between the two groups, and was correlated with the Basic Psychological Needs Scale scores. Patients had a significantly lower acceptance rate of the proposal in the intrinsic motivation condition than controls, and this intrinsic motivated tendency was correlated with the satisfaction in their basic psychological needs. As with other substance use disorders, IGD was associated with a lower level of internal motivation, which was related to the dissatisfaction of basic psychological needs such as autonomy, competence, and relationship.

Objectives Internet gaming disorder (IGD) is known to be related to stress and the serotonin-transporter-linked polymorphic region (5-HTTLPR) that is known to be associated with stress and has been studied to affect various psychiatric illness outbreaks. We tried to examine the relationship between stress, 5-HTTLPR and IGD. Methods A total of 59 participants with IGD, diagnosed according to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria and 67 normal controls (NC) were enrolled. The IGD group and the NC were compared using chisquare test and independent sample t-test, and logistic regression analysis was used to examine the relationship between stress, the 5-HTTLPR, and IGD. Results The mean scores for anxiety, impulsivity and stress were significantly higher in the IGD group than in the NC. In addition, there was a significant association between stress and IGD [odds ratio (OR) = 1.172, 95% confidence interval (CI) = 1.008-1.362]. Conclusions This study showed that stress would affect IGD. Therefore, the evaluation and management of stress should be included in the diagnosis and treatment of IGD.

Objectives: Previous studies have reported that internet addiction (IA) is associated with attention-deficit/hyperactivity disorder (ADHD) consistently. However, in terms of gender, there are controversial findings. We aimed to investigate the relation between IA and self-acknowledged ADHD traits among female college students in Japan. Methods: The study questionnaire consisted of questions about demographics, Adult ADHD Self-Report Scale-V1.1 Part A (ADHD screener) and Young's Internet Addiction Test (IAT). When four or more items are more frequent than the cut-off on ADHD screener, the subject was categorized into students with a positive ADHD screen. We defined students with total IAT score of 70 and higher as IA. Results: A total number of respondents was 369 (mean age: $19.0{\pm}0.7years$). Seventy-seven subjects were screened positive on ADHD screener (20.9%). Students with a positive ADHD screen scored significantly higher on the IAT ($54.2{\pm}14.2$ vs. $42.5{\pm}11.3$). The rates of IA in students with and without a positive ADHD screen were 18.2% and 1.0%, respectively. Conclusion: Results of this study demonstrated the relation between IA and self-evaluated ADHD traits among female college students in Japan. Appropriate education for students on how to use the internet properly will be necessary to prevent IA.
