Use of it has led researchers to identify four behavior patterns they consider peculiar to BPD: abandonment, engulfment, annihilation fears; demandingness and entitlement; treatment regressions; and ability to arouse inappropriately close or hostile treatment relationships.

它的应用使研究者们能够将边缘人格分类为四种特有的行为方式：1。离弃感，吞没感，灭绝恐惧；2。苛求和权利欲；3。治疗衰退；4。唤起不恰当亲近或者敌对的治疗关系的能力。
