About this study
Official title: Emotion and Craving Regulation Among Individuals With Internet Gaming Disorder: Cognitive Appraisal and Mindfulness Capacities
To investigate the potential deficits in emotion and craving regulation capacities of drug-naïve young adults with Internet gaming disorder as compared with healthy controls.
Read the detailed description
The purpose of this study is to examine the differences in young adults' capacities of utilizing cognitive appraisal versus mindfulness to regulate negative emotions and/or craving in response to negative affective stimuli or gaming cues, respectively. This project will be conducted in Beijing, China.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Emotion Regulation TaskProcedure or surgery
Participants are instructed to complete the emotion assessment after Look or Decrease the neutral or negative pictures. The "Decrease" asks the participants to use "cognitive reappraisal" or "mindfulness" strategies to decrease the intensity of emotion, whereas the "Look" asks the participants to look naturally at the picture. First, the "look" or "decrease" is displayed on the computer for 2 s. Then, a neutral or negative picture is presented on the screen for 7s. Finally, participants will rate the intensity of their emotion for 4s. Then, they have 1s-3s to relax before the next trial. In the meantime, Skin conductance activities will be recorded using a constant voltage with 1-cm 3 AgAg/Cl electrodes attached to the medial phalanx surfaces of the middle and index fingers of the nondominant hand.
Craving Regulation TaskProcedure or surgery
Participants are instructed to complete the craving assessment after Look or Decrease the neutral or gaming pictures. The "Decrease" asks the participants to use "cognitive reappraisal" or "mindfulness" strategies to decrease the intensity of craving, whereas the "Look" asks the participants to look naturally at the picture. First, the "look" or "decrease" is displayed on the computer for 2 s. Second, a neutral or gaming picture is presented on the screen for 7s. Third, participants rate the intensity of their craving for 4s. Then, they have 1s-3s to relax before the next trial. In the meantime, Skin conductance activities will be recorded using a constant voltage with 1-cm 3 AgAg/Cl electrodes attached to the medial phalanx surfaces of the middle and index fingers of the nondominant hand.

Questions about this trial
What is this clinical trial studying?
A study testing Emotion Regulation Task and Craving Regulation Task in people with Internet Gaming Disorder and Emotion Regulation, run by Beijing Normal University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Behavioral outcome (time frame: 30- 40 minutes after training). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04110548, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2021; AzTrials last refreshed its copy on 7 Nov 2026.
