A Phase 2 interventional study of tDCS with real stimulation and tDCS with sham stimulation in Addiction and Internet Gaming Disorder, sponsored by Seoul National University Hospital. Completed at 1 site in Korea, Republic of. Open to participants aged 18 Years to 50 Years. Per ClinicalTrials.gov, last updated 2020-03-24.

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.

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

A total of 25 patients will be allocated into active comparator with real stimulation with tDCS.
Device: tDCS with real stimulation
A total of 25 patients will be allocated into sham comparator with sham stimulation with tDCS.
Device: tDCS with sham stimulation
tDCS is a non-invasive brain stimulation. Real stimulation includes 2mA current for 20 minutes per session. Two sessions a day for 5 consecutive days (Total: 10 sessions) will be applied.
Sham stimulation includes 0mA current for 20 minutes per session. Two sessions a day for 5 consecutive days (Total: 10 sessions) will be applied.

The stop signal task is a neurocognitive task for assessing response inhibition.
Time frame: baseline, 5 weeks, 25 weeks
Barratt impulsiveness scale-11
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.
Time frame: 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.
Time frame: baseline, 5 weeks, 25 weeks
Late positive potential in the cue reactivity event-related potential
Event-related potential measures with cue reactivity task
Time frame: 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.
Time frame: baseline, 1 week, 5 weeks, 25 weeks
