抑郁症不仅包括对主要情绪的干扰，还包括情绪如何随时间波动。然而，确切地说，哪些情感动态模式与抑郁症状有关尚不清楚；抑郁症与情感变异性和不稳定性的增加有关，但也与对情感变化的更大抵抗（惯性）有关。在本文中，我们认为这些矛盾的发现源于许多被忽视的方法/分析因素，我们使用一种新的范式和分析方法来解决这些问题。参与者（N = 99）被预先挑选为各种各样的抑郁症状的代表，他们观看了一系列情感电影片段，并在每个电影片段的基线和之后对他们的情绪进行了评分。我们还使用经验抽样法评估了参与者在1周内的日常生活影响。在控制不同情绪动态测量之间的重叠时，抑郁症状与实验室中较高的消极情绪惯性独立相关，并且在实验室和日常生活中都具有较大的消极情绪可变性。相比之下，无论是在日常生活中还是在实验室中，抑郁症状都与较高的情感不稳定性无关。
Depression not only involves disturbances in prevailing affect, but also in how affect fluctuates over time. Yet, precisely which patterns of affect dynamics are associated with depressive symptoms remains unclear; depression has been linked with increased affective variability and instability, but also with greater resistance to affective change (inertia). In this paper, we argue that these paradoxical findings stem from a number of neglected methodological/analytical factors, which we address using a novel paradigm and analytic approach. Participants (N = 99), preselected to represent a wide range of depressive symptoms, watched a series of emotional film clips and rated their affect at baseline and following each film clip. We also assessed participants' affect in daily life over 1 week using experience sampling. When controlling for overlap between different measures of affect dynamics, depressive symptoms were independently associated with higher inertia of negative affect in the lab, and with greater negative affect variability both in the lab and in daily life. In contrast, depressive symptoms were not independently related to higher affective instability either in daily life or in the lab.
