A core feature of borderline personality disorder (BPD) is the tendency to evaluate one's experience with extreme polarity (i.e., feeling all good or all bad; Beck, Freeman, & Davis, 2004; Kernberg, 1975; Linehan, 1993). In this investigation, we examined the polarity of within-person reports of experience in individuals with BPD and healthy adults over the course of a 21-day, experience-sampling diary. We applied multilevel modeling techniques (Rafaeli, Rogers, & Ravelle, 2007) to capture the within-person covariance of momentary reports of negative and positive features of experience, either affective or relational. Our data indicated significantly greater polarity in reports of affective and relational experiences in BPD that increased during heightened interpersonal stress. We also examined the association of affective and relational polarity to reports of impulsive behaviors (e.g., self-injury, substance use, etc.) and found evidence that increased polarity in reports of affective (in low-stress contexts) and relational experiences (in high-stress contexts) predicted increased rate of reports of impulsive behaviors. Together, these data present strong evidence for the role of polarized experiences in BPD, and have implications for the treatment of individuals with this disorder.
边缘型人格障碍（BPD）的一个核心特征是倾向于用极端的极性来评估自己的体验（即感觉全好或全坏；Beck、Freeman 和 Davis，2004；Kernberg，1975；Linehan，1993）。在这项研究中，我们在 21 天的经验采样日记中，检查了 BPD 患者和健康成年人个体内体验报告的极性。我们应用多层次建模技术（Rafaeli、Rogers 和 Ravelle，2007）来捕捉瞬间报告的经验的消极和积极特征的个体内协方差，无论是情感的还是关系的。我们的数据表明，BPD 患者的情感和关系体验的报告极性显著增加，并且在人际压力增加时增加。我们还检查了情感和关系极性与冲动行为（例如，自残、药物使用等）报告之间的关联，发现情感（在低压力环境中）和关系体验（在高压力环境中）报告的极性增加预测冲动行为报告率的增加。总之，这些数据为极性体验在 BPD 中的作用提供了强有力的证据，并对治疗这种障碍的个体具有启示意义。
