This study examined how the use of co-game play, which implies specific behavioral condition, changes the influence and direction of the sensation seeking, gender, and identity stability, which are predictors on game addiction. The results of this study are as follows. First, sensation seeking had no significant effect on game addiction. However, the main effect of co-play on game addiction was confirmed. Second, the moderating effects of gender on co-play and game addiction were significant. It indicates that co-play has a greater impact on game addiction in female than male.

Objectives The aim of this study was to find out the psychological changes associated with internet addiction between before and after the military drill among the young male army recruits. Methods All 1091 participants were army recruits aged from 19 to 22 years who participated in the 5-week military drill. They were assessed with some self-reported questionnaires [Sociodemographic questionnaires, Young's Internet Addiction Scale (IAS), the State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory (BDI), the Barratt Impulsiveness Scale (BIS), the Attention-Deficit/Hyperactivity Disorder Self-Rated Scale (ASRS)]. They were divided into two groups, One is the internet addiction tendency group and the other is non-addiction group according to the IAS score. And the severity of the internet addiction tendency, depression, anxiety and impulsiveness were evaluated by the IAS, the STAI, the BDI, the BIS, the ASRS before and after military drill. Results The result of the paired t-test shows that the IAS, the STAI, the BDI, the BIS, the ASRS scores decreased after military drill in both non-addiction group and internet addiction tendency group. The result of the repeated measures ANOVA shows that there is an interaction effect between the changes of ASRS-hyperactivity (F = 23.437, p < 0.001), ASRS-impulsiveness (F = 4.896, p = 0.027), BIS-total (F = 4.057, p = 0.044), BIS-motor impulsiveness (F = 13.609, p < 0.001) scores and groups. The result of the generalized estimating equation shows that internet addiction tendency is associated with ASRS-inattention (${\beta}=0.075$, p < 0.001), ASRS-hyperactivity (${\beta}=0.092$, p = 0.002), STAI-trait anxiety (${\beta}=0.046$, p < 0.001), BIS-motor impulsiveness (${\beta}=0.119$, p = 0.028). Conclusions The results show that psychopathologies such as internet addiction tendency, depression, anxiety, impulsiveness may improve after military drill regardless of the groups. Internet addiction tendency may be related to the ASRS-inattention, ASRS-hyperactivity, STAI-trait anxiety, motor-impulsiveness. So these findings may be considered in the treatment of internet addiction in terms of the impulsiveness control.

Purpose: The purpose of this study was to analyze addiction prevention related content shown in middle school text books. Methods: Using a combination of the terms "addiction", "drug", "medicine", "personal preference", "smoking", "drinking", "sex", "misuse" or "abuse" as key words, the researchers screened the table of contents of 23 randomly selected middle school textbooks from the 2009 curriculum. Finally 13 textbooks (physical education=10, health=3) were selected for this study, and analyzed using Krippendorff's contents analysis. Results: Through indepth discussion and investigation of the relevant textbooks, content related to addiction prevention included material addiction (77.8%) and behavioral addiction (22.2%). The construction of addiction prevention in middle school textbooks included understanding addiction, rejection of peer temptation, and empowerment of self-control. Conclusion: When developing an intervention for addiction prevention that targets middle school students, education with accurate addiction information must be considered so that the students have the correct knowledge about addiction and addiction prevention. Additionally, the ability to reject peer temptation when invited to act upon related addiction behaviors should be treated seriously. The empowerment of self-control is also important, and can be promoted through strengthening self-regulation competence.

Drug addiction is a severe psychiatric disorder characterized by the compulsive pursuit of drugs of abuse despite potential adverse consequences. Although several decades of studies have revealed that psychostimulant use can result in extensive alterations of neural circuits and physiology, no effective therapeutic strategies or medicines for drug addiction currently exist. Changes in neuronal connectivity and regulation occurring after repeated drug exposure contribute to addiction-like behaviors in animal models. Among the involved brain areas, including those of the reward system, the striatum is the major area of convergence for glutamate, GABA, and dopamine transmission, and this brain region potentially determines stereotyped behaviors. Although the physiological consequences of striatal neurons after drug exposure have been relatively well documented, it remains to be clarified how changes in striatal connectivity underlie and modulate the expression of addiction-like behaviors. Understanding how striatal circuits contribute to addiction-like behaviors may lead to the development of strategies that successfully attenuate drug-induced behavioral changes. In this review, we summarize the results of recent studies that have examined striatal circuitry and pathway-specific alterations leading to addiction-like behaviors to provide an updated framework for future investigations.

Objective : The purpose of this study was to investigate the relationship between the pattern of computer game play and emotional and behavioral characteristics of 5th and 6th grade elementary school children in Jeonju city. Methods : Fifth and sixth graders from two elementary schools (N=413, M=214, F=199) were chosen to participate in this study. The participants completed self-report questionnaires designed by the authors, and were also evaluated based on a computer game addiction scale, state-trait anxiety inventory for children, children's depression inventory and Piers-Harris children's self-esteem scale. The parents of the participants determined the disruptive behavior rating scale of the participants. Results : Positive links were reported between the pattern of computer game play (years of computer game experience, average length of each computer game play session, average time spent on computer game play per day, and average frequency of computer game play per week) and scores of computer game addiction scale. In addition, significant correlation was found between the internalized problems of children (trait anxiety, state anxiety, depression, and self-esteem), and computer game addiction scale score, among both sexes (p<0.01). There were significant correlations between game addiction scale score and inattention (p<0.01) as well as total attention deficit hyperactivity disorder (ADHD) score (p<0.05) in girls. Conclusion : Our findings suggest that computer game addiction is related to symptoms of internalizing, particularly to the trait anxiety. Significant positive correlations between game addiction scale score and externalized behavioral problems were found only in girls.

Social media is an essential part of everyday life in modern society and plays an important role in communicating the ideal body image. With the increased prevalence and high popularity of social media, the problems associated with the addictive use of social media have become a social issue. Utilizing social comparison theory, this study examined (1) the effect of appearance related photo activities on body satisfaction through appearance comparison and (2) the moderating effect of Instagram addiction in relationships among appearance related photo activity, appearance comparison, and body satisfaction. We tested the proposed relationships between research variables using multi-group structural equation modeling analysis on a sample of 346 young female Instagram users. The sample was divided into two groups of high and low addicted Instagram users. The results of this study showed that the appearance related photo activity positively influenced appearance comparison for both high and low addiction groups. For the high addiction group, the effect of appearance comparison on body satisfaction was not statistically significant; however, this relationship was significant and negative for the low addiction group. A significant moderating effect of Instagram addiction was found in the relationship between appearance related photo activity and appearance comparison.

This study identified the relationship between adolescents' alienation and stress responses, and examined the mediating model of smart media addiction moderated by behavioral activation system (BAS) on alienation and stress responses. Participants were 361 male and female students in middle and high schools located at Seoul metropolitan area. PROCESS Macro 3.5 Model 7 was used for analysis of the moderating mediating effect. Results revealed that adolescents' alienation and BAS were positively correlated with smart media addiction and stress responses, while smart media addiction was positively correlated with stress responses. In a moderated mediating model for stress responses, there was significant interaction effect of alienation and BAS; conditionally indirect effect of alienation was not significant in groups with very low BAS. These findings suggest that adolescents who feel alienation are more likely to experience stress responses by overindulging themselves in using smart media. The moderating effect suggests that this effect is stronger with higher levels of BAS.

Drug addiction influences most communities directly or indirectly. Increasing studies have reported the relationship between circadian-related genes and drug addiction. Per2 disrupted mice exhibited more vulnerable behavioral responses against some drugs including methamphetamine (METH). However, its roles and mechanisms are still not clear. Transcriptional profiling analysis in Per2 knockout (KO) mice may provide a valuable tool to identify potential genetic involvement and pathways in enhanced behavioral responses against drugs. To explore the potential genetic involvement, we examined common differentially expressed genes (DEGs) in the striatum of drug naïve Per2 KO/wild-type (WT) mice, and before/after METH treatment in Per2 KO mice, but not in WT mice. We selected 9 common DEGs (Ncald, Cpa6, Pklr, Ttc29, Cbr2, Egr2, Prg4, Lcn2, and Camsap2) based on literature research. Among the common DEGs, Ncald, Cpa6, Pklr, and Ttc29 showed higher expression levels in drug naïve Per2 KO mice than in WT mice, while they were downregulated in Per2 KO mice after METH treatment. In contrast, Cbr2, Egr2, Prg4, Lcn2, and Camsap2 exhibited lower expression levels in drug naïve Per2 KO mice than in WT mice, while they were upregulated after METH treatment in Per2 KO mice. qRT-PCR analyses validated the expression patterns of 9 target genes before/after METH treatment in Per2 KO and WT mice. Although further research is required to deeply understand the relationship and roles of the 9 target genes in drug addiction, the findings from the present study indicate that the target genes might play important roles in drug addiction.

Objectives : This study was aimed at investigating the relationship between internet game addiction and emotional and behavioral characteristics of students both in the 5th and 6th grade of elementary school and in middle school. Methods : Two elementary schools and two middle schools were chosen to participate. The students completed selfreport questionnaires designed by the authors, called the Internet Game Addiction Scale, Korean youth self-report (K-YSR). Results : Compared to previous studies, the rates of those in the obvious game addiction group were much lower in this study. We defined the upper 10% of internet game addiction scores as a high risk user group and the lower 10% as a control group. There were significant differences between the groups with respect to the the ages at which internet gaming began, the frequency of game play per week, and the average length of each game playing session. Significant associations were also found between the level of internet game addiction and the withdrawn and delinquency subscales of the K-YSR. However, the association between game addiction and the withdrawn subscale was found only in middle school students. Conclusion : The findings from this study suggested that withdrawn and delinquent behaviors could be predictors of internet game addiction. Results also suggested the importance of early childhood intervention for preventing the development of more severe psychopathology in early adolescence.
