Major Depressive Disorder (MDD) is a prevalent disorder involving disturbances in mood. There is still much to understand regarding precisely how emotions are disrupted in individuals with MDD. In this study, we used a network approach to examine the emotional disturbances underlying MDD. We hypothesized that, compared to healthy controls, individuals diagnosed with MDD would be characterized by a denser emotion network, indicating that their emotion system is more resistant to change. Indeed, results from a 7-day experience sampling study revealed that individuals with MDD had a denser overall emotion network than did healthy controls. Moreover, this difference was driven primarily by a denser negative, but not positive, network in MDD participants. These findings suggest that the disruption in emotions that characterizes depressed individuals stems from a negative emotion system that is resistant to change.
重度抑郁症（MDD）是一种常见的情绪障碍疾病。关于MDD患者的情绪究竟是如何受到干扰的，仍有许多需要了解的地方。在本研究中，我们采用网络分析方法来研究MDD潜在的情绪障碍。我们假设，与健康对照组相比，被诊断为MDD的个体的情绪网络更为密集，这表明他们的情绪系统对变化更具抵抗力。事实上，一项为期7天的经验取样研究结果显示，MDD患者的整体情绪网络比健康对照组更为密集。此外，这种差异主要是由MDD参与者中更密集的消极情绪网络而非积极情绪网络驱动的。这些发现表明，抑郁症患者情绪紊乱的根源在于一个抗拒变化的消极情绪系统。
