The purpose of this article is to reveal whether traits can predict the core processes constituting borderline personality disorder (BPD). A large sample, including many with BPD, completed personality questionnaires and reported trigger and symptom experiences 5 times per day for 2 weeks. Multilevel modeling revealed first that symptoms were strongly contingent upon concurrent triggers and that BPD's association to symptoms was largely due to this contingency. Second, personality traits predicted all components of this process: trigger experiences, symptom intensity, and the contingency of the symptoms on triggers. However, normal personality traits only partially accounted for the heightened experience of triggers, elevated symptoms, and magnified reactivity to triggers among those with BPD. Thus, normal personality traits are capable of explaining the dynamic processes characteristic of clinical disorders, meaning that normal traits can elucidate even complex dynamic clinical processes. However, traits appear to only partially contain the active ingredients responsible for the core process in BPD. Aspects of the disorder other than traits may account for the heightened trigger experience, elevated symptom intensity, and magnified reactivity to triggers in those with BPD.

本文的目的是揭示特质是否能够预测构成边缘型人格障碍（BPD）的核心过程。一个包含许多BPD患者的大样本完成了人格问卷，并在两周内每天报告5次触发因素和症状体验。多层次模型首先揭示，症状强烈依赖于同时出现的触发因素，并且BPD与症状的关联很大程度上归因于这种依赖性。其次，人格特质预测了这一过程的所有组成部分：触发因素体验、症状强度以及症状对触发因素的依赖性。然而，正常人格特质仅部分解释了BPD患者中触发因素体验的增强、症状的加重以及对触发因素反应性的放大。因此，正常人格特质能够解释临床障碍的动态过程特征，这意味着正常特质甚至可以阐明复杂的动态临床过程。然而，特质似乎仅部分包含了导致BPD核心过程的有效成分。除特质之外的障碍方面可能解释了BPD患者中触发因素体验的增强、症状强度的增加以及对触发因素反应性的放大。（PsycInfo数据库记录（c）2022美国心理学会，保留所有权利）
