The subjects were 2844 fourth graders participated in the Korean Youth Panel Survey between 2004 and 2008. Internet game use, the levels of aggression, self-esteem, self-control, stress, depression, attachment to parents, parental control, attachment to teachers, and attachment to peers were measured by 5-point Likert scales. The result showed that gender was the most effective factor influencing the initial level of, the rate of changes, an increase or decrease in the rate of changes in Internet game use and levels of aggression. Boys showed higher levels of Internet game use and aggression than girls. Children with higher self-esteem, self-control and lower stress and depression showed lower levels of Internet game use and aggression. The levels of Internet game use at fourth grade was positively correlated with later increase in the levels of aggression. Also, the faster increase in Internet game use caused faster increase in the levels of aggression later. Based on the results, preventive measures such as limiting the opportunities to access Internet games might be worth to decrease the aggressive behaviors among children.展开更多

The following case reports provide detailed information on two boys, ages 16 and 20 years respectively, who are compulsive and enthusiastic internet gamers, to the exclusion of family communication, school activities, academic performance, participation in sports and dating.

A literature search was conducted using the database Web of Science.METHODS: Over the last 15 years, the number of Internet users has increased by 1000%, and at the same time, research on addictive Internet use has proliferated. Internet addiction has not yet been understood very well, and research on its etiology and natural history is still in its infancy. In 2013, the American Psychiatric Association included Internet Gaming Disorder in the appendix of the updated version of the Diagnostic and Statistical Manual for Mental Disorders(DSM-5) as condition that requires further research prior to official inclusion in the main manual, with important repercussions for research and treatment. To date, reviews have focused on clinical and treatment studies of Internet addiction and Internet Gaming Disorder. This arguably limits the analysis to a specific diagnosis of a potential disorder that has not yet been officially recognised in the Western world, rather than a comprehensive and inclusive investigation of Internet-use related addictions(including problematic Internet use) more generally. RESULTS: The systematic literature review identified a total of 46 relevant studies. The included studies used clinical samples, and focused on characteristics of treatment seekers and online addiction treatment. Four main types of clinical research studies were identified, namely research involving(1) treatment seeker characteristics;(2) psychopharmacotherapy;(3) psychological therapy; and(4) combined treatment. CONCLUSION: A consensus regarding diagnostic criteria and measures is needed to improve reliability across studies and to develop effective and efficient treatment approaches for treatment seekers.展开更多

The following search words were used, both alone and in combination: f MRI, internet addiction, internet dependence, functional neuroimaging. The search was conducted on April 20^(th), 2015 and yielded 58 records. Inclusion criteria were the following: Articles written in English, patients' age ≥ 18 years, patients affected by IAD, studies providing f MRI results during resting state or cognitive/emotional paradigms. Structural MRI studies, functional imaging techniques other than f MRI, studies involving adolescents, patients with comorbid psychiatric, neurological or medical conditions were excluded. By reading titles and abstracts, we excluded 30 records. By reading the full texts of the 28 remaining articles, we identified 18 papers meeting our inclusion criteria and therefore included in the qualitative synthesis.RESULTS: We found 18 studies fulfilling our inclusion criteria, 17 of them conducted in Asia, and including a total number of 666 tested subjects. The included studies reported data acquired during resting state or different paradigms, such as cue-reactivity, guessing or cognitive control tasks. The enrolled patients were usually males(95.4%) and very young(21-25 years). The most represented IAD subtype, reported in more than 85% of patients, was the internet gaming disorder, or videogame addiction. In the resting state studies, the more relevant abnormalities were localized in the superior temporal gyrus, limbic, medial frontal and parietal regions. When analyzing the task related fmri studies, we found that less than half of the papers reported behavioral differences between patients and normal controls, but all of them found significant differences in cortical and subcortical brain regions involved in cognitive control and reward processing: Orbitofrontal cortex, insula, anterior and posterior cingulate cortex, temporal and parietal regions, brain stem and caudate nucleus.CONCLUSION: IAD may seriously affect young adults' brain functions. It needs to be studied more in depth to provide a clear diagnosis and an adequate treatment.展开更多

In this study, 14 students with Internet addiction disorder and 14 matched healthy controls underwent proton-magnetic resonance spectroscopy to measure cerebral function. Results demonstrated that the ratio of N-acetylaspartate to creatine decreased, but the ratio of cho- line-containing compounds to creatine increased in the bilateral frontal lobe white matter in people with Internet addiction disorder. However, these ratios were mostly unaltered in the brainstem, suggesting that frontal lobe function decreases in people with Internet addiction disorder.展开更多

文摘目的:本研究旨在通过荟萃分析探讨网络/手机/游戏问题性使用或成瘾与非自杀性自伤(non-suicidal selfinjury,NSSI)之间的关联,为未来的预防和干预策略提供科学依据。方法:根据研究目的,制定检索策略并注册研究方案后,系统性检索了6个数据库(Web of Science、PubMed、Embase、中国知网、万方和重庆维普)中直到2024年6月23日的记录。对纳入研究进行质量评估,然后进行问题性使用或成瘾与NSSI关联的比值比(odds ratio,OR)的合并。此外,进行了敏感性分析和亚组分析。结果:24篇文章被纳入,涉及研究对象266816人。总体上,网络/手机/游戏问题性使用或成瘾者有更高的NSSI风险(OR=2.47,95%置信区间=2.22~2.76)。控制人口学信息、心理健康和家庭经济状况等混杂因素后,合并的调整后比值比(OR=1.71,95%置信区间=1.58~1.84)验证了这些结论。此外,不论是网络还是手机问题性使用/成瘾都有更高的NSSI风险;不论是大学生还是小学/初中/高中生的网络/手机/游戏问题性使用或成瘾都有更高的NSSI风险。另外,在中国人群中的发现与全球范围内的发现一致。结论:网络/手机/游戏问题性使用或成瘾与NSSI显著相关。应从此关联出发,制定相应的行为预防和干预措施。
