It is a well-known fact that Internet addiction adversely affects mental health of adolescents. This study was conducted to determine whether there is a difference in the experience of depression according to the level of Internet addiction. Participants included 73,238 middle and high school students from the Korean Youth Risk Behavior Web-based Survey (KYRBWS) conducted in 2010. The level of Internet addiction and the experience of depression were assessed using self-diagnosis questionnaires. Multiple logistic regression analysis was used to identify the association between Internet addiction and depression. High-risk and potential-risk Internet users were 1.61 times and 1.21 times more likely to experience depression, respectively, than normal Internet users. The increase in depression was more significant in girls students. Acknowledging the connection between Internet addiction and depression, the problem should be tackled from the perspective of school health by providing systematic Internet addiction prevention and treatment programs.

Objectives : Internet addiction or pathologic internet use is one of the major mental health problems in children and adolescents in Korea. Internet addiction is defined as uncontrollable, markedly time-consuming internet use, which lasts for a period of at least six months. Internet addiction results in poor academic performance and negative parent-child relationships. By using $^{18}F$-fluorodeoxyglucose-positron emission tomography (FDG-PET), we investigated the effects of internet addiction on functional changes occurring in the adolescent brain. Methods : Adolescent patients with an internet addiction (4 boys and 2 girls; $15.6{\pm}1.2$ years) participated in this study. Eight healthy young adults (5 males and 3 females; 18-30 years old) with no previous history of psychiatric illness also participated as normal controls. Brain FDG-PET data was obtained with the participants in the resting condition and with no addictive stimuli. Results : Statistic parametric mapping analysis of the brain FDG-PET data revealed hypometabolic changes in the visual information processing circuits and hypermetabolic changes in the prefrontal areas in the adolescents with internet addiction, as compared with normal controls (p<.001). Conclusion : These results suggest a neuronal adaptation to excessive visual stimulation and synaptic plasticity due to internet addiction.

Purpose: This study was designed to build a theoretical frame to provide practical help to prevent and manage adolescent internet game addiction by developing a prediction model through a comprehensive analysis of related factors. Methods: The participants were 1,318 students studying in elementary, middle, and high schools in Seoul and Gyeonggi Province, Korea. Collected data were analyzed using the SPSS program. Decision Tree Analysis using the Clementine program was applied to build an optimum and significant prediction model to predict internet game addiction related to various factors, especially parent related factors. Results: From the data analyses, the prediction model for factors related to internet game addiction presented with 5 pathways. Causative factors included gender, type of school, siblings, economic status, religion, time spent alone, gaming place, payment to Internet cafe$\acute{e}$, frequency, duration, parent's ability to use internet, occupation (mother), trust (father), expectations regarding adolescent's study (mother), supervising (both parents), rearing attitude (both parents). Conclusion: The results suggest preventive and managerial nursing programs for specific groups by path. Use of this predictive model can expand the role of school nurses, not only in counseling addicted adolescents but also, in developing and carrying out programs with parents and approaching adolescents individually through databases and computer programming.

Objective : The aims of this study were to explore the relations of internet addiction to depression, impulsivity, and obsessive-compulsivity in adolescents. Methods : 1410 high school students (male=611, female=799 : mean age=$16.2{\pm}0.7$) were included in this study. The questionnaire consisted of items on demographic characteristics and internet use pattern. We assessed the level of internet addiction using Young's internet addiction scale (IAS) Barratt impulsiveness scale (BIS) and Maudsley obsessive compulsive inventory (MOCI) were also self-rated. In this study, We defined upper 25% of IAS as 'addiction group' and lower 25% as 'non-addiction group'. Results : The results were as follows ; 1) Male students had significantly higher mean scores on Internet addiction scale than females and there was significantly higher rate of male students in addiction group. 2) The addiction group spent more time for internet use, especially for games than non-addiction group. 3) The addiction group showed significantly higher total scores on BDI, BIS, and MOCI than non-addiction group. 4) Significant associations have been found between the level of internet addiction and depression, impulsivity, and obsessive-compulsivity, respectively. Conclusion : Depression, impulsivity, and obsessive-compulsivity could be significant factors predicting internet addiction. Especially, direct effect of impulsivity could be the most significant to explain internet addiction. Adolescents with high impulsivity may be vulnerable to internet addiction.

Objectives : This study compared covert narcissistic propensity in adolescents with internet addiction tendency to normal adolescents. Further, we investigated the correlation between such propensities and anonymity in cyberspace, presence feeling and interactivity in internet gaming, and achievement motivation in adolescents with internet addiction tendencies. Methods : Male middle school students with internet addiction tendencies (Addiction Tendency Group, N=27) and normal students (Control Group, N=29) were recruited. The scale of internet use, Covert Narcissism Scale, scale of achievement motivation, scale of anonymity in cyberspace, scale of presence feeling in internet games, and the scale of interactivity in internet games were administered. A comparison of the average scores and correlation analyses were performed. Results : 1) Compared with Control Group, the Addiction Tendency Group showed significantly higher scores on all subscales of the Covert Narcissism Scale, and both the scale of presence feeling and that of interactivity in internet games. Further, the score on the scale of achievement motivation for the Addiction Tendency Group was significantly lower than that of the Control Group. 2) In the Addiction Tendency Group, the scores on several subscales of the Covert Narcissism Scale were significantly positively correlated with the scores on the scale of presence feeling in internet games, anonymity in cyberspace, and interactivity in internet games. However, in the Control Group, the scores of several subscales on the Covert Narcissism Scale were significantly negatively correlated with the score on the scale of achievement motivation, and was significantly positively correlated with the score on the scale of interactivity in internet games. There were no other significant correlations between the scores on the subscales of the Covert Narcissism Scale and the scores of either presence feeling in internet games or anonymity in cyberspace. Conclusion : These results suggested that adolescents with a tendency to be addicted to the internet exhibited higher covert narcissistic propensities than normal adolescents and that the covert narcissistic tendencies were related with presence feeling in cyber games as well as with anonymity in cyberspace.
