BACKGROUND
Individuals with Borderline Personality Disorder (BPD) feel rejected even when socially included. The pathophysiological mechanisms of this rejection bias are still unknown. Using the Cyberball paradigm, we investigated whether patients with BPD, display altered physiological responses to social inclusion and ostracism, as assessed by changes in Respiratory Sinus Arrhythmia (RSA).
METHODS
The sample comprised 30 patients with BPD, 30 with remitted Major Depressive Disorder (rMDD) and 30 Healthy Controls (HC). Self-report ratings of threats toward one's fundamental need to belong and RSA reactivity were measured immediately after each Cyberball condition.
RESULTS
Participants with BPD showed lower RSA at rest than HC. Only patients with BPD, reported higher threats to fundamental needs and exhibited a further decline in RSA after the Inclusion condition.
CONCLUSIONS
Individuals with BPD experience a biased appraisal of social inclusion both at the subjective and physiological level, showing higher feelings of ostracism and a breakdown of autonomic regulation to including social scenarios.
背景
边缘型人格障碍（BPD）患者即使在被社会接纳时也会感到被排斥。这种排斥偏见的病理生理机制尚不清楚。我们使用赛博球范式，通过呼吸性窦性心律不齐（RSA）的变化评估，研究了BPD患者对社会接纳和排斥的生理反应是否改变。
方法
样本包括30名BPD患者、30名缓解期重度抑郁症（rMDD）患者和30名健康对照者（HC）。在每种赛博球情境后立即测量对自身基本归属感需求的威胁的自我报告评分和RSA反应性。
结果
BPD患者静息时的RSA低于HC。只有BPD患者报告对基本需求的威胁更高，并且在被接纳情境后RSA进一步下降。
结论
BPD患者在主观和生理层面都经历了对社会接纳的偏差评估，表现出更高的被排斥感以及在包括社交场景时自主调节的崩溃。
