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.

Barratt impulsiveness scale-11 is a self-report questionnaire consisting of 30 items. Each question has a 4-point scale ranging from 1 (rarely/never) to 4 (almost always/always). This scale scores three subscales: attentional impulsiveness, motor impulsiveness, and nonplanning impulsiveness. The total score ranges from 30 to 120 and higher scores indicate greater impulsivity.
| baseline, 5 weeks, 25 weeks |
| Anti-saccade error rate in the attentional bias task | The attentional bias task is measured by anti-saccade task using eye-tracking analysis for assessing attentional bias on Internet gaming stimuli. | baseline, 5 weeks, 25 weeks |
| Late positive potential in the cue reactivity event-related potential | Event-related potential measures with cue reactivity task | baseline, 5 weeks, 25 weeks |
| Visual analogue scale | Subjective craving for Internet gaming ranging from 0 to 10. Higher score represents higher craving for gaming. | baseline, 1 week, 5 weeks, 25 weeks |
