Interpersonal dysfunction is a core feature of personality disorders, often affecting close relationships. Nevertheless, little is known about the moment-to-moment dynamic processes by which personality pathology contributes to dysfunctional relationships. Here, we investigated the role of physiological attunement during a conflict discussion in romantic couples oversampled for personality pathology. We hypothesized that physiological coregulation would be disrupted in individuals with personality pathology, subsequently predicting short-term discord and long-term relationship dissatisfaction. One hundred twenty-one couples completed a 10-min discussion about an area of disagreement while cardiovascular physiology and behavior were recorded. We quantified coregulation using a dynamical systems model of heart rate changes. We found that greater interpersonal problem severity was associated with more contrarian coregulation, exacerbating negative affect and interpersonal perceptions. Furthermore, the extent to which coregulation was associated with increased discord prospectively predicted relationship dissatisfaction 1 year later. Altogether, this work sheds light on a pathway by which personality pathology contributes to problems in romantic relationships. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

冲突期间生理上的协调紊乱预示着人格障碍患者的短期不和谐和长期关系功能障碍。

人际功能障碍是人格障碍的核心特征，通常会影响亲密关系。然而，对于人格病理学导致机能失调的人际关系的瞬间动态过程知之甚少。在这里，我们调查了人格病理学过度采样的浪漫情侣在冲突讨论期间生理协调的作用。我们假设人格病理学的个体会破坏生理调节，从而预测短期的不和谐和长期的关系不满。在记录心血管生理和行为的同时，一百二十一对夫妇完成了关于分歧区域的十分钟讨论。我们使用心率变化的动态系统模型量化了共调。我们发现，人际交往问题的严重性与逆势调整的趋势更大，加剧了负面影响和人际交往的感受。此外，一年后，调节与不和谐的程度增加有关，前瞻性预测了对关系的不满意。总而言之，这项工作揭示了人格病理学导致恋爱关系中的问题的途径。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。这项工作揭示了人格病理学导致恋爱关系中的问题的途径。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。这项工作阐明了人格病理学导致恋爱关系中的问题的途径。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
