Emotional and behavioral variability are unifying characteristics of borderline personality disorder (BPD). Ambulatory assessment (AA) has been used to quantify this variability in terms of the categorical BPD diagnosis, but evidence suggests that BPD instead reflects general personality pathology. This study aimed to clarify the conceptualization of BPD by mapping indices of variability in affect, interpersonal behavior, and perceptions of others onto general and specific dimensions of personality pathology. A sample of participants who met diagnostic criteria for BPD (n = 129) and healthy controls (n = 47) reported on their daily interactions during a 21-day AA protocol. Multilevel SEM was used to examine associations between shared and specific variance in maladaptive traits with dynamic patterns of functioning. The authors found that variability is an indicator of shared trait variance and Negative Affectivity, not any other specific traits, reinforcing the idea that BPD is best understood as general personality pathology.
情感和行为的可变性是边缘型人格障碍（BPD）的统一特征。动态评估（AA）已被用于根据 BPD 的分类诊断来量化这种可变性，但有证据表明，BPD 反映的是一般人格病理学。本研究旨在通过将情感、人际关系行为和对他人的感知的变异性指标映射到一般和特定的人格病理学维度上，来阐明 BPD 的概念化。一项符合 BPD 诊断标准的参与者（n=129）和健康对照组（n=47）的样本在 21 天的 AA 协议期间报告了他们的日常互动。多层次 SEM 用于检查适应不良特征的共享和特定方差与功能动态模式之间的关联。作者发现，可变性是共享特质方差和负性情绪的指标，而不是任何其他特定特质的指标，这强化了这样一种观点，即 BPD 最好被理解为一般人格病理学。
