INTERVENTIONAL
Conditions
Summary
Internet Gaming Disorder (IGD) involves impaired cognitive control linked to reduced social reward and dACC-DLPFC brain circuit dysfunction. Enhancing social reward may restore this circuit and improve symptoms. This study uses psychological interventions and neuroimaging to explore and treat IGD.

Interventions
Based on previous research, this study has made significant innovations and optimizations within the traditional framework of Acceptance and Commitment Therapy (ACT). We have specifically developed a systematic self-help training module aimed at enhancing social reward, which includes components such as social scenario experience, social skills training, and the improvement of social reward sensitivity. A single-blind randomized controlled trial will be conducted, dividing IGD participants into two groups. The SRI group (Social Reward Intervention group) will receive a psychological self-help training program designed to improve social reward, while the other (Control group) will receive a course introducing general knowledge about Internet Gaming Disorder. Both groups will have identical learning durations and modalities. The self-help training consists of 8 sessions, delivered twice weekly through a blended online and offline learning format, lasting approximately one month.
A single-blind randomized controlled trial is conducted. 30 people, assigned to Control group, was provided with standard educational courses introducing general knowledge about Internet Gaming Disorder. Assessments including standardized scales, behavioral tests, and neuroimaging are conducted once before and once after the intervention. During the course, participants will receive twice-weekly online guidance sessions totaling eight sessions. The entire intervention lasts approximately one month, with follow-up assessments conducted at 3, 6, and 12 months post-intervention.
