About this study
Official title: High Working Memory Load to Reduce IGD Cravings: N-Back Task
To test whether high working memory load can effectively reduce the craving for IGD.
Read the detailed description
This project is to use 1-back task and 3-back task to reduce the craving of internet gamers. To test whether high working memory load can effectively reduce the craving for IGD. This project will be conducted in Beijing, China, based on a large sample of internet gamers.
- Conditions
- Internet Gaming Disorder
- Being tested
- n-back task
- Medical subject headings
- Internet Addiction Disorder
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
n-back taskBehavioural
All participants will be asked to finish the 3-back task and the 1-back task. The 3-back task and the 1-back task will be carried out at intervals to avoid the influence between different tasks. The sequence of the 3-back task and the 1-back task will be counterbalanced across participants.
| Study group | Role | What they receive |
|---|---|---|
| High Working memory load: n-back task | Experimental | During the intervention, each participant of this group will finish the 3-back task. Receives: Behavioral: n-back task |
| Low Working memory load: n-back task | Experimental | During the intervention, each participant of this group will finish the 1-back task. Receives: Behavioral: n-back task |
What is being measured
The primary outcome is the main question the study is designed to answer.
The craving of internet gamers
The craving of internet gamers is measured by a single item Visual Analogue Scale with 1 to 7 likert score.
Measured: 0-1 minutes before each set of cue
The craving of internet gamers after cue
The craving of internet gamers is measured by a single item Visual Analogue Scale with 1 to 7 likert score.
Measured: 0-1 minutes after showing cue
The craving of internet gamers after tasks
The craving of internet gamers is measured by a single item Visual Analogue Scale with 1 to 7 likert score.
Measured: 0-1 minutes after finishing each block of tasks
