We examined the symptoms network of Internet Gaming Disorder (IGD). We recruited 793 heavy game players online and 184 of them were diagnosed with IGD. We measured IGD via the 27-item IGD Scale and analyzed symptoms to examine how they interacted with each other to drive the addictive behaviors. Furthermore, we added motives and psychological well-being variables into the network. We found that the most central symptoms were conflict, withdrawal, and tolerance. Overall, two distinct groups of symptoms were discovered: one group for addictive symptoms and the other for psychological consequences. Copyright © 2022 Elsevier B.V. All rights reserved.
