本研究调查了基线冲动，拒绝敏感性，并与健康个体和回避型人格障碍相比，边缘型人格障碍的个体对压力源的反应。边缘组表现出更大的冲动性比回避和健康组无论是在延迟折扣任务与真实的金钱奖励和自我报告的反应压力，此外，这些发现不能解释共同发生的物质使用障碍。两个人格障碍组（相对于健康组）对压力源的痛苦反应同样升高。边缘型和回避型群体对人际与非人际性质的压力源也有更多的适应不良反应，而健康群体则没有。最后，自我报告的冲动反应的压力与基线冲动延迟折扣任务，更大的自我报告的反应，人际比非人际压力与拒绝敏感性。这项研究突出了导致边缘型人格障碍患者冲动行为的明显弱点。
This research investigated baseline impulsivity, rejection sensitivity, and reactions to stressors in individuals with borderline personality disorder compared to healthy individuals and those with avoidant personality disorder. The borderline group showed greater impulsivity than the avoidant and healthy groups both in a delay-discounting task with real monetary rewards and in self-reported reactions to stressors; moreover, these findings could not be explained by co-occurring substance use disorders. Distress reactions to stressors were equally elevated in both personality disorder groups (relative to the healthy group). The borderline and avoidant groups also reported more maladaptive reactions to a stressor of an interpersonal vs. non-interpersonal nature, whereas the healthy group did not. Finally, self-reported impulsive reactions to stressors were associated with baseline impulsivity in the delay-discounting task, and greater self-reported reactivity to interpersonal than non-interpersonal stressors was associated with rejection sensitivity. This research highlights distinct vulnerabilities contributing to impulsive behavior in borderline personality disorder.
