Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to use the modification training of cognitive bias to ameliorate the severity and symptoms of Internet gaming disorders(IGD); the neural mechanisms of cognitive bias modification and its effect during cued-induced craving task in subjects with IGD will be investigated as well. This project will be conducted in Beijing, China.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The investigators assigned subjects to two training groups and collected pre - and post-test data

Primary Study Purpose

BASIC_SCIENCE

Blinding Strategy

DOUBLE

Participants Investigators

double blind: both participants and experimenters won't know which group is training group or sham control group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CBM training

participants have to complete the picture assessment task ; Approach-avoidance Task(AAT) and cue-induced task in the fMRI；data on game-craving level, game hours, the ability of self-control and emotion regulation are also collected.

Half of the participants will be random-assigned into the CBM training group; Each participant will do these task twice( e.g. Before training and after training)

Group Type EXPERIMENTAL

CBM training

Intervention Type PROCEDURE

participants will be random-assigned into one of training groups. Participants in the modification group will receive modified training of 400 trials for six sessions during six days, the same as the sham group.The difference between these two groups is the proportion of push/pull trials. The sequence of the interventions will be counterbalanced across participants, and the callback will be conduct after one week.

Sham training

participants have to complete the picture assessment task ; Approach-avoidance Task(AAT) and cue-induced task in the fMRI；data on game-craving level, game hours, the ability of self-control and emotion regulation are also collected.

Half of the participants will be random-assigned into the sham training group; Each participant will do these task twice( e.g. Before training and after training)
