Romantic relationships are defined by emotion dynamics, or how the emotions of one partner at a single timepoint can affect their own emotions and the emotions of their partner at the next timepoint. Previous research has shown that the level of these emotion dynamics plays a role in determining the state and quality of the relationship. However, this research has not examined whether the estimated emotion dynamics change over time, and how the change in these dynamics might relate to relationship outcomes, despite changes in dynamics being likely to occur. We examined whether the magnitude of variation in emotion dynamics over time was associated with relationship outcomes in a sample of 148 couples. Time-varying vector autoregressive models were used to estimate the emotion dynamics for each couple, and the average and standard deviation of the dynamics over time was related to relationship quality and relationship dissolution 1–2 years later. Our results demonstrate that certain autoregressive and cross-lagged parameters do show significant variation over time, and that this variation is associated with relationship outcomes. Overall, this study demonstrates the importance of accounting for change in emotion dynamics over time, and the relevance of this change to the prediction of future outcomes.

情绪动态随时间的变化与未来的关系结果相关

浪漫关系是由情绪动态定义的，或者一个伴侣在单个时间点的情绪如何影响他们自己的情绪以及伴侣在下一个时间点的情绪。先前的研究表明，这些情绪动态的水平在决定关系的状态和质量方面发挥着作用。然而，这项研究并没有研究估计的情绪动态是否会随着时间的推移而变化，以及这些动态的变化如何与关系结果相关，尽管动态的变化可能会发生。我们以 148 对夫妇为样本，研究了情绪动态随时间变化的幅度是否与关系结果相关。使用时变向量自回归模型来估计每对夫妻的情绪动态，动态随时间的平均值和标准差与1-2年后的关系质量和关系解除有关。我们的结果表明，某些自回归和交叉滞后参数确实随着时间的推移显示出显着的变化，并且这种变化与关系结果相关。总的来说，这项研究证明了解释情绪动态随时间变化的重要性，以及这种变化与预测未来结果的相关性。
