Borderline personality disorder (BPD) is characterized by dichotomous thinking, biases in processing emotion-related information, impulsive responding, and identity disturbance - each of which may affect how individuals respond to assessment items. This study used item-response theory tree models to examine the association between number of self-reported BPD symptoms and response style bias on the NEO Five Factor Inventory-3, administered annually from ages 18 to 20 to 2196 community participants enrolled in the Pittsburgh Girls Study. Small to moderate negative correlations emerged between number of BPD symptoms and midpoint responding. Small correlations emerged between BPD symptoms and extremity responding. These patterns did not vary by age. Participants who endorsed higher initial BPD symptoms reported lower extraversion over time, whereas those initially endorsing midpoint extroversion reported greater decreases in BPD severity. Low initial agreeableness was associated with higher BPD symptom slopes. The current study found only small associations between response style biases and BPD symptoms among a sample with subthreshold symptoms for diagnosis.
边缘性人格障碍（BPD）的特征是二分法思维、处理与情绪相关信息时的偏差、冲动反应和身份认同障碍——每一项都可能影响个体对评估项目的反应方式。本研究使用项目反应理论树模型，对匹兹堡女孩研究中招募的2196名社区参与者进行了研究，这些参与者年龄在18至20岁至21岁之间，每年接受一次《大五人格量表-3》（NEO Five Factor Inventory-3）测试，以检验自我报告的BPD症状数量与反应风格偏差之间的关联。BPD症状数量与中点反应之间出现了小到中等程度的负相关。BPD症状与极端反应之间出现了小的相关性。这些模式在不同年龄之间没有差异。随着时间的推移，最初认可较高BPD症状的参与者报告外向性较低，而最初认可中点外向性的参与者报告BPD严重程度下降幅度更大。低初始宜人性与较高的BPD症状斜率相关。在一个诊断症状低于阈值的样本中，本研究发现反应风格偏差与BPD症状之间只有很小的关联。
