Experts recognized several characteristics in kids or teenagers, and affective imbalance, negative affectivity, bad emotionality, poor anger, worst mental handle, impulsivity, and violence, that may ready yourself to borderline pathology [elizabeth.grams., Refs.

Comparable conclusions was in fact gotten because of the Stepp and you may collaborators in two after the research (19, 20) with a larger attempt varied ranging from 2,212 and dos,282 people/teens.
