Internet Gaming Disorder
Conditions
Brief summary
This project aims to investigate whether anodal tDCS of dlPFC enhances cognitive regulation over craving an emotions.
Interventions
BEHAVIORALCraving behavioral intervention
The CBI was given once a week for 6 weeks, conducted by four therapists. A pair of therapists was randomly assigned to a CBI+ group. Each session included 5 parts in 2.5-3 hours: warming-up exercise, discussion about the homework from the last session, main structured activity, brief summary, and the homework assignment. There were 6 sessions with each focused on a topic: recognize craving and its relationship with IGD; reduce craving through ameliorating the salience of cues and irrational beliefs, withdrawal symptoms and other negative affects; enhance self-monitoring and control for craving through time management training; relieve fulfillment of psychological needs through Internet use and attenuate the relation between craving and gaming behaviors through coping skill training
