Relationships between specific borderline personality disorder (BPD) features and facets of impulsivity (negative and positive urgency, premeditation, perseverance, and sensation seeking) were examined in a sample of 227 undergraduate students, oversampled to include many with elevations on a measure of borderline features. Most facets of impulsivity were positively correlated with borderline features, except for sensation seeking, which showed a mixed pattern of relationships with specific BPD features. In regression models, negative urgency was the strongest predictor of all BPD features scales, including affective instability, identity problems, negative relationships, and self-harm. Premeditation, positive urgency, and sensation seeking demonstrated incremental validity over negative urgency in predicting some BPD features; however, significant beta weights were negative for sensation seeking, suggesting that it may be protective or adaptive for BPD, unlike other forms of impulsivity. This study provides evidence for variation in how types of impulsivity contribute to different BPD features and demonstrates the importance of examining BPD features on the subscale level.
在一个由 227 名大学生组成的样本中，研究了特定边缘型人格障碍（BPD）特征与冲动性的各个方面（消极冲动、积极冲动、预谋、毅力和寻求刺激）之间的关系，该样本对具有边界特征升高的个体进行了过度抽样。冲动性的大多数方面都与边缘特征呈正相关，除了寻求刺激，它与特定 BPD 特征之间的关系呈现出混合模式。在回归模型中，消极冲动是所有 BPD 特征量表的最强预测因子，包括情感不稳定、身份问题、负面关系和自残。预谋、积极冲动和寻求刺激在预测某些 BPD 特征方面显示出了比消极冲动更高的增量有效性；然而，对于寻求刺激，显著的β权重为负数，这表明它可能对 BPD 具有保护或适应性，与其他形式的冲动不同。这项研究提供了关于不同类型的冲动如何导致不同 BPD 特征的证据，并证明了在子量表水平上检查 BPD 特征的重要性。
