Signal detection theory measures of thermal responsivity were examined to determine whether differences in reported pain experienced during self-injurious behavior in female patients with borderline personality disorder (BPD) are explained by neurosensory factors and/or attitudinal factors (response bias). Female patients with BPD who do not experience pain during self-injury (BPD-NP group) were found to discriminate more poorly between noxious thermal stimuli of similar intensity, low P(A), than female patients with BPD who experience pain during self-injury (BPD-P group), female patients with BPD who do not have a history of self-injury (BPD-C group), and age-matched normal women. The BPD-NP group also had a higher response criterion, B (more stoical) than the BPD-C group. These findings suggest that 'analgesia' during self-injury in patients with BPD is related to both neurosensory and attitudinal/psychological abnormalities.
对热反应性的信号检测理论测量进行了研究，以确定边缘性人格障碍（BPD）女性患者在自我伤害行为中报告的疼痛差异是否由神经感觉因素和/或态度因素（反应偏差）所解释。发现自我伤害时无疼痛体验的BPD女性患者（BPD-NP组）在区分相似强度的有害热刺激（低P(A)）方面比自我伤害时有疼痛体验的BPD女性患者（BPD-P组）、无自我伤害史的BPD女性患者（BPD-C组）以及年龄匹配的正常女性表现更差。BPD-NP组的反应标准B（更坚忍）也高于BPD-C组。这些发现表明，BPD患者自我伤害时的“镇痛”与神经感觉和态度/心理异常均有关。
