The study used regularized partial correlation network analysis (EBICglasso) to examine the structure of DSM-5 internet gaming disorder (IGD) symptoms (network 1); and the associations of the IGD symptoms in the network with different types of motivation as defined in the self-determination theory i.e., intrinsic motivation (engaging in an activity for something unrelated to the activity), identified regulation (engaging in the activity because it aligns with one's values and/or goals), external regulation (engagement in activity being driven by external rewards and/or approval), and amotivation (engaging in an activity without often understanding why) (network 2). Participants were 968 adults from the general community. They completed self-rating questionnaires covering IGD symptoms and different types of motivation. The findings for network 1 showed mostly positive connections between the symptoms within the IGD network. The most central symptom was loss of control, followed by continuation, withdrawal symptoms, and tolerance. In general, these symptoms were more strongly connected with each other than with the rest of the IGD symptoms. The findings for network 2 showed that the different types of motivation were connected differently with the different IGD symptoms. For instance, the likeliest motivation for the preoccupation and escape symptoms is intrinsic motivation, and for negative consequences, it is low identified regulation. Overall, the findings showed a novel understanding of the structure of the IGD symptoms, and the motivations underlying them. The clinical implications of the findings for assessment and treatment of IGD are discussed.
该研究采用正则化偏相关网络分析（EBICglasso）来考察DSM-5 网络游戏障碍（IGD）症状的结构（网络 1）；以及网络中 IGD 症状与自我决定理论中定义的不同动机类型的关联，即内在动机（从事与活动无关的活动）、认同调节（从事与自己的价值观和/或目标一致的活动）、外在调节（从事受外部奖励和/或认可驱动的活动）和动机缺乏（无目的活动）（网络 2）。参与者是来自普通社区的 968 名成年人。他们完成了涵盖 IGD 症状和不同动机类型的自我评估问卷。网络 1 的研究结果表明，IGD 网络内的症状之间主要存在正相关。最核心的症状是失控，其次是持续、戒断症状和耐受性。总的来说，这些症状彼此之间的联系比与其他 IGD 症状的联系更紧密。网络 2 的研究结果表明，不同类型的动机与不同的 IGD 症状以不同的方式联系在一起。例如，占据和逃避症状最有可能的动机是内在动机，而对于负面后果，则是低认同调节。总的来说，这些发现为理解 IGD 症状的结构以及它们背后的动机提供了新的认识。讨论了这些发现对 IGD 评估和治疗的临床意义。
