Neurofeedback for Internet Gaming Addiction

Not Applicable

Completed

• Conditions: Internet Gaming Disorder

• Registration Number: NCT06063642
• Lead Sponsor: University of Macau

Brief Summary

The primary aim of this study is to evaluate the therapeutic potential of real-time functional magnetic resonance imaging (MRI) neurofeedback in alleviating internet gaming disorder (IGD) symptoms by training individuals with such symptoms to down-regulate the activity in their reward-processing-related midbrain regions.

Primary Outcome Measures

Name	Time	Method
Change from Baseline in self-reported urge for internet gaming as assessed by Visual Analog Scales (1 to 100)	Up to 30 days after the intervention session

Secondary Outcome Measures

Name	Time	Method
Change in reward-related activity during exposure to internet gaming videos	Up to 3 days	Participants will complete cue-reactivity tasks in which they are exposed to video clips captured from the dependent mobile game before and after the intervention. Functional MRI data will be collected to measure their pre- to post-intervention changes in the brain reward processing pathways.
Change in inhibitory response in the affective Go/Nogo task	Up to 3 days	This task that uses affective Chinese characters as stimuli will be used to examine changes in inhibitory control performance as well as changes in brain activity associated with this cognitive process pre- to post-intervention.
