Though it is tough to identify temperamental proportions inside the identification off mature customers, authors discovered that higher spoil reduction and novelty seeking to (in conjunction with youth event and you can adolescent psychopathology) can be regarded as predictive of very early BPD. According to so it studies, Kaess mais aussi al. (60) present in a controlled research contrasting 33 BPD teens, thirty five systematic regulation, and you may 31 suit victims one large harm reduction and you may novelty trying but lowest reward dependence represent a biological susceptability to have development BPD.

Equivalent results was indeed acquired because of the Stepp and collaborators in two pursuing the assessment (19, 20) which have a bigger test ranged anywhere between 2,212 and 2,282 pupils/teens. They confirmed the latest role regarding negative affectivity and impulsivity inside anticipating BPD, actually from the 14 ages (19), and you will emphasized the importance of large hobby minimizing sociability for the youthfulness once the precursors of one’s sickness.
