The aim of this project is to compare the effects of the newly discovered parietal cortex (Pz electrode point) with the dorsolateral prefrontal cortex (F3 electrode point), which has been commonly used in previous studies, and to further develop a closed-loop intervention method of real-time tDCS under on-line electroencephalography (EEG-tDCS), so as to realise an individualised diagnosis and treatment for online game addicts. This study is divided into two parts, the first part to explore the effectiveness of the new target, using a randomised group design, using tDCS intervention, the subject population is online game addicts, the sample size is about 120. Participants underwent baseline information collection on the first day of the experiment including: basic demographic information, assessment of internet addiction severity and craving; EEG collection in resting state as well as task state (Game Cue Response Task, Signal Stop Task, Iowa Gambling Task). The tDCS intervention under the game cue response task was conducted on the second and third days of the experiment, divided into four groups (the first and second groups were the true-false stimulation groups with the anode at the trapezius muscle at the base of the right neck and the cathode at the subject\'s central parietal cortex; and the third and fourth groups had the anode at the subject\'s left dorsolateral prefrontal cortex, and the cathode at the trapezius muscle at the base of the right neck), with 20 min of intervention each time and the Game craving level was assessed before and after the intervention. Resting-state and task-state (Game Cue Response Task, Signal Stop Task, Iowa Gambling Task) EEG acquisitions were performed at the end of the intervention.The second part of the EEG-tDCS closed-loop intervention was conducted, using a randomised group design with a sample size of about 60 subjects who are addicted to online games. On the first day of the experiment, baseline information was collected, and a personalised EEG classifier model was built for each subject based on the EEG signals of the game cue response task; on the second and third days of the experiment, EEG-tDCS closed-loop intervention was conducted, divided into true intervention and sham intervention groups, with the true intervention group identifying whether subjects were in an addictive state in real time under the game cue response task, and addictive states were identified by giving real-time short-time short-time short-time short-time short-time short-time short-time intervention at target locations. The real-time short-term tDCS intervention was given at the target location for a total duration of 20 minutes, and the level of game craving was assessed after the intervention; at the end of the intervention, the EEG was collected in the resting state and the task state (game cue response task, signal stopping task, and Iowa gambling task). The two-part experiment followed up subjects with weekly post-intervention versus one-month post-intervention gaming severity assessments, with resting-state and task-state (gaming cue-response task, signal-stopping task, Iowa gambling task) electroencephalogram acquisitions.

This study aims to investigate the intervention effects of navigated repetitive transcranial magnetic stimulation (rTMS) on craving regulation in individuals with internet gaming disorder (IGD). The primary objectives include: (1) examining the impact of navigated rTMS over the dorsolateral prefrontal cortex (DLPFC) on the gaming cravings, and craving regulation capacity; and (2) exploring the potential neural mechanisms by which rTMS over the DLPFC improves craving intensity, and craving regulation ability.

This project aims to investigate (1) the efficacy of light therapy on internet gaming disorder (IGD); (2) the underlying neural mechanisms of such efficacy
NCT05479344
The present study will explore the underlying mechanisms of problematic Internet and smartphone use by focusing on how and when environmental factors affect the positive psychological intervention factors. Hence, the present study will provide scientific empirical evidence to design and formulate follow-up intervention strategies. Aims: I. Apply the dynamic system model of addictive behavior execution in Chinese adolescents with problematic Internet and smartphone use and use longitudinal data to track and explore the underlying mechanisms of environmental factors and personal factors on problematic Internet and smartphone use. II. Identify positive psychological intervention factors that effectively prevent and reduce problematic Internet and smartphone use according to the interview and provide empirical evidence for other intervention designs. III. Conducting a positive psychological intervention in an adolescent population to verify the protective effect of positive psychology factors on problematic Internet and smartphone use. Hypotheses: I. Environmental factors (e.g., child abuse and trauma, parenting behaviors, teachers' encouragement, peer support) will affect the problematic Internet and smartphone use through personal characteristics (e.g., meaning in life); II. The effect of environmental factors on problematic Internet and smartphone use through personal characteristics will be moderated by other positive psychological intervention factors (e.g., character strengths); III. Positive psychological intervention (e.g., meaning-based intervention, strengths-based intervention) is an effective intervention strategy to prevent and reduce problematic Internet and smartphone use.

Internet Gaming Disorder (IOB) is an important problem that is increasingly prevalent all over the world and can be prevented before it develops. This research is a single-blind, randomized controlled experimental study to evaluate the effect of Internet-based education given to parents on children's Internet gaming disorder. 96 children and their parents studying in the central districts of a province and at risk for the development of IOBB were divided into intervention (48) and control groups (48) according to the randomization list. The "I know digital games" training consisting of three modules and 10 videos was given to the intervention group via the website prepared by the researchers, and no intervention was made to the control group. The research data were collected at three different times using the "Internet Gaming Disorder Scale Short Form" (İOOBÖ9-SF) and the forms developed by the researchers. In the analysis of data; descriptive statistics, Chi-square, Mann Whitney U test, and repeated measures ANOVA were used. Before the analysis, eight missing data in the control group were estimated with regression estimation models from intent to treat protocols. Statistical significance level p ≤0.05 was taken in all analyzes. Parents and children in the intervention and control groups were similar in terms of sociodemographic characteristics and playing characteristics (p\>0.05). It would be beneficial to involve parents in the interventions that nurses will make for primary school children in order to prevent IOB.

To investigate the potential deficits in emotion and craving regulation capacities of drug-naïve young adults with Internet gaming disorder as compared with healthy controls.
NCT03347643
In this study, the investigators aimed to investigate the effect of transcranial direct current stimulation (tDCS) on clinical status of Internet game addiction. The clinical status of Internet game addiction includes severity of addiction symptom, subjective craving for gaming, response inhibition and cue reactivity. The investigators hypothesized that real stimulation with tDCS on the dorsolateral prefrontal cortex will have higher effectiveness on severity of addiction symptom, subjective craving for gaming, response inhibition and cue reactivity rather than sham stimulation with tDCS.

To investigate whether and how the CBM training will alleviate the symptoms of addiction in Internet gaming disorders.
