Emotional instability has been extensively considered the main core of the borderline personality disorder (BPD) that is characterised by an important bias towards emotional information. The aim of this study was to determine the emotional bias in patients with BPD by means of an emotional Stroop paradigm.
Sixty-one women (38 Borderline Personality Disorder outpatients and 23 healthy matched control subjects) were included. All of them underwent a computerised version of an emotional Stroop which included four valences: borderline-related negative, negative, positive and neutral.
The results showed that BPD patients were slower in spotting the ink of the words [F(1.59)=4.33; p=0.04], and this effect was mainly for borderline-related and neutral words. Likewise, the more severe the BPD the slower the subjects [F(2.57)=4.81; p=0.012], indicating difficulties in processing information.
The findings suggest that the emotional dysregulation may account for selective processing with emotional stimulus, which in turn triggers emotional responses in BPD patients, rather than to reflect a more general hypervigilance and an attentional bias for any kind of stimulus.
情绪不稳定已被广泛认为是边缘型人格障碍(BPD)的主要核心,其特征是对情绪信息存在重要偏差。本研究的目的是通过情绪Stroop范式确定BPD患者的情绪偏差。
纳入61名女性(38名BPD门诊患者和23名健康匹配对照者)。她们均接受了计算机化的情绪Stroop测试,该测试包括四种效价:与BPD相关的负面、负面、正面和中性。
结果显示,BPD患者识别单词颜色的速度较慢[F(1.59)=4.33;p=0.04],且这种效应主要针对与BPD相关的单词和中性单词。同样,BPD越严重,受试者的反应速度越慢[F(2.57)=4.81;p=0.012],表明信息处理存在困难。
研究结果表明,情绪调节障碍可能是对情绪刺激进行选择性处理的原因,这反过来会触发BPD患者的情绪反应,而不是反映出对任何类型刺激的更普遍的过度警觉和注意力偏差。
