Clinical Trial Summary

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.

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.

Intervention

Procedure:
• Emotion Regulation Task
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 Task
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.
