Psychophysiology and Emotion Regulation in BPD

描述(由申请人提供)：这项拟议的研究测试了Linehan(1993)的理论，即边缘性人格障碍(BPD)是一种普适性情绪失调的障碍。Linehan将情绪失调定义为对各种背景下的情绪刺激的高度敏感和强烈反应。在这项研究中，呼吸窦性心律失常(RSA)、皮肤电导(SC)和自我报告的生理指标将被用来调查BPD患者是否表现出跨多种情绪和多种背景的高情绪反应，从而显示出普遍情绪失调的迹象。参与者将参与一项与个人相关的录音带任务(情景1)，其中他们将听到对他们感到害怕、愤怒、悲伤和没有情绪的时间的描述，以及一项标准化的任务(情景2)，其中他们观看标准化的恐惧、愤怒、悲伤和中性电影。据预测，与正常对照组相比，BPD和GAD患者在基线时将表现出情绪敏感的迹象。据预测，当暴露在与个人相关的标准化恐惧诱导下时，BPD组和GAD组将表现出比正常对照组更高的情绪反应。然而，当暴露于个人相关和标准化的愤怒和悲伤诱导时，预计BPD组将表现出比GAD组和正常对照组更高的情绪反应，从而表明存在普遍情绪失调的证据。本研究是第一个除了自我报告外，使用交感和副交感(即迷走神经张力)生理测量来研究BPD情绪失调的研究。

DESCRIPTION (provided by applicant): The proposed research tests Linehan's (1993) theory that Borderline Personality Disorder (BPD) is a disorder of pervasive emotion dysregulation. Linehan defines emotion dysregulation as high sensitivity and intense responding to emotional stimuli across various contexts. In this study, physiological measures of respiratory sinus arrhvthmia (RSA), skin conductance (SC), and self-report will be used to investigate if BPD individuals show indications of pervasive emotion dysregulation by exhibiting heightened emotional responses across multiple emotions and multiple contexts. Participants will engage m a personally-relevant audiotape task (context 1) in which they will hear a description of a time when they felt afraid, angry, sad, and no emotion, and a standardized task (context 2) where they view standardized fear, anger, sad, and neutral films. It is predicted that, at baseline, BPD and GAD patients will show indications of emotional sensitivity compared with normal controls. When exposed to the personally-relevant and standardized fear inductions, it is predicted that the BPD and GAD groups will exhibit increased emotional responding compared to normal controls. However, when exposed to the personally-relevant and standardized anger and sadness inductions, it is expected that the BPD group will exhibit higher emotional responding than both GAD and normal control groups, thus indicating evidence of pervasive emotion dysregulation This study is the first to study emotion dysregulation in BPD using both sympathetic and parasympathic (i.e., vagal tone) physiological measures in addition to self-report.
