Individuals with internet addiction (IA) show difficulties in emotion regulation. However, they could effectively employ emotion regulation strategies when instructed. We speculate that this discrepancy might be caused by maladaptive emotion regulation choices. Recent studies indicated that decreased activity of the left frontal cortex could be a neural marker of reappraisal use. To address this problem, individuals with IA ( = 17, IA group) and healthy individuals ( = 23, healthy control [HC] group) were required to choose an emotion regulation strategy between reappraisal and distraction to regulate their emotions varying in emotional intensity and valence. We also compared the resting state frontal alpha asymmetry (FAA) of these 2 groups. The results replicated more choices of reappraisal in low- versus high-intensity emotional contexts across groups. More importantly, the IA group chose reappraisal less frequently compared with the HC group, irrespective of emotional intensity. Furthermore, we found individuals with IA have lower FAA than healthy controls, and FAA shows a positive correlation with the use of reappraisal. These findings suggest that IA alters individuals' patterns of emotion regulation choice and impairs frontal activities, causing difficulties in emotion regulation.
个体有网络成瘾（IA）表现出情绪调节困难。然而，当他们被指导时，他们可以有效地使用情绪调节策略。我们推测这种差异可能是由于情绪调节选择不当造成的。最近的研究表明，左前额叶皮层活动减少可能是重新评价使用的神经标记。为了解决这个问题，网络成瘾者（ = 17，IA 组）和健康个体（ = 23，健康对照组 [HC] 组）被要求在重新评价和分心之间选择一种情绪调节策略来调节情绪强度和效价不同的情绪。我们还比较了这两组的静息状态下额侧α不对称（FAA）。结果在情绪强度和效价不同的情况下，两组都复制了更多的选择重新评价。更重要的是，IA 组与 HC 组相比，选择重新评价的频率较低，而与情绪强度无关。此外，我们发现网络成瘾者的 FAA 低于健康对照组，并且 FAA 与重新评价的使用呈正相关。这些发现表明，IA 改变了个体的情绪调节选择模式，损害了额叶活动，导致情绪调节困难。
