Brief 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.

Condition or disease Intervention/treatment Phase
Internet Gaming Disorder Emotion Regulation Procedure: Emotion Regulation Task Procedure: Craving Regulation Task Not Applicable

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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 80 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Basic Science
Official Title: Emotion and Craving Regulation Among Individuals With Internet Gaming Disorder: Cognitive Appraisal and Mindfulness Capacities
Actual Study Start Date : September 26, 2019
Estimated Primary Completion Date : March 30, 2020
Estimated Study Completion Date : May 30, 2020

Arm Intervention/treatment
Experimental: HCs on Emotion Regulation
Participants are screened using the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), Young's online Internet addiction test (YIAT), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and so on. They are instructed to complete the emotion regulation task on the computer.
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.

Experimental: IGDs on Craving Regulation
Participants are screened using the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), Young's online Internet addiction test (YIAT), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and so on. They are instructed to complete the craving regulation task on the computer.
Procedure: 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.




Primary Outcome Measures :
  1. Behavioral outcome [ Time Frame: 30- 40 minutes after training ]
    Participants' ratings of negative emotion and their skin conductance levels (SCL).

  2. Behavioral outcome [ Time Frame: 40- 60 minutes after training ]
    Participants' ratings of negative emotion and their skin conductance levels (SCL).

  3. Behavioral outcome [ Time Frame: 60- 80 minutes after training ]
    Participants' ratings of cravings and their skin conductance levels (SCL).
