Borderline Personal Disord Emot Dysregul. 2022 Feb 1;9(1):6. doi: 10.1186/s40479-021-00175-5.
Borderline Personality Disorder involves strong interpersonal disruptions, often associated with early maltreatment. However, the individual capacities which alter BPD-related interpersonal problems are unclear. Here, we examine two contributors to interpersonal functioning: interoceptive accuracy and parasympathetic activity. Interoceptive accuracy is the ability to correctly perceive body states, such as how quickly one's heart is beating, and has been associated with emotional experience and various crucial social capacities. Similarly, parasympathetic activity is related to social processing and inhibition of impulses. As such, both may contribute to BPD interpersonal symptoms, albeit different types of interpersonal problems.
Sixty-five individuals completed the Inventory of Interpersonal Problems and the Millon Clinical Multiaxial Inventory followed by a task to assess interoceptive accuracy, the heart rate monitoring task, in which participants counted their heartbeats while concurrent physiological data was recorded; and an assessment of vagal tone, used as an index of regulatory flexibility.
Participants who reported poor interpersonal boundaries, consistent with borderline personality disorder styles, had worse interoception, whereas those high in aggression had lower vagal tone. Borderline personality symptoms overall were related to IA and significantly to vagal tone.
These findings suggest that interoceptive accuracy is associated with interpersonal problems, where people are overly influenced or enmeshed with others, possibly to compensate for the absence of their physical and emotional awareness.
边缘型人格障碍涉及严重的人际功能紊乱，常与早期虐待相关。然而，改变与边缘型人格障碍相关人际问题的个体能力尚不清楚。在此，我们研究人际功能的两个影响因素：内感受准确性和副交感神经活动。内感受准确性是正确感知身体状态的能力，比如自己心跳的速度，并且与情感体验及各种关键的社交能力相关。同样，副交感神经活动与社交处理和冲动抑制有关。因此，两者可能都对边缘型人格障碍的人际症状有影响，尽管是不同类型的人际问题。
65名个体完成了人际问题量表和米隆临床多轴量表，随后进行一项评估内感受准确性的任务，即心率监测任务，参与者在记录同步生理数据的同时数自己的心跳；以及一项迷走神经张力评估，用作调节灵活性的指标。
报告人际边界差（符合边缘型人格障碍类型）的参与者内感受更差，而攻击性高的参与者迷走神经张力更低。总体而言，边缘型人格症状与内感受准确性相关，且与迷走神经张力显著相关。
这些发现表明，内感受准确性与人际问题有关，即人们过度受到他人影响或与他人纠缠在一起，这可能是为了弥补自身身体和情感意识的缺失。
