Borderline personality disorder (BPD) is a serious mental illness characterized by instability in affective, cognitive, and interpersonal domains. BPD co-occurs with several mental disorders and has robust, positive associations with the general factors of psychopathology (p-factor) and personality disorders (g-PD). Consequently, some researchers have purported BPD to be a marker of p, such that the core features of BPD reflect a generalized liability to psychopathology. This assertion has largely stemmed from cross-sectional evidence and no research to date has explicated the developmental relationships between BPD and p. The present study aimed to investigate the development of BPD traits and the p-factor by examining predictions of two opposing frameworks: dynamic mutualism theory and the common cause theory. Competing theories were evaluated to determine which perspective best accounted for the relationship of BPD and p from adolescence into young adulthood. Data were drawn from the Pittsburgh Girls Study (PGS; N = 2,450) and included yearly self-assessments of BPD and other internalizing and externalizing indices from ages 14 to 21. Theories were examined using random-intercept cross-lagged panel models (RI-CLPMs) and network models. Results indicated that neither dynamic mutualism nor the common cause theory could fully explain the developmental relations between BPD and p. Instead, both frameworks were partially supported, with p found to strongly predict within-person change in BPD at several ages. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
边缘型人格障碍（BPD）是一种严重的精神疾病，其特征是情感、认知和人际关系领域的不稳定。BPD 与几种精神障碍共同发生，与精神病理学的一般因素（p 因素）和人格障碍（g-PD）有很强的正相关。因此，一些研究人员认为 BPD 是 p 的标志物，即 BPD 的核心特征反映了对精神病理学的普遍易感性。这一说法主要源于横断面证据，迄今为止尚无研究阐明 BPD 和 p 之间的发展关系。本研究旨在通过检查两种对立框架的预测来研究 BPD 特征和 p 因素的发展：动态互惠理论和共同原因理论。评估了竞争理论，以确定哪种观点最能解释 BPD 和 p 从青春期到成年早期的关系。数据来自匹兹堡女孩研究（PGS；N=2450），包括从 14 岁到 21 岁的 BPD 以及其他内化和外化指标的年度自我评估。使用随机截距交叉滞后面板模型（RI-CLPM）和网络模型检验了这些理论。结果表明，动态互惠或共同原因理论都不能完全解释 BPD 和 p 之间的发展关系。相反，这两个框架都得到了部分支持，p 因素被发现可以强烈预测几个年龄段的 BPD 个体内变化。（PsycInfo 数据库记录（c）2023 APA，保留所有权利）。
