In psychoanalytic traumatology today traumatizing is understood as som
ething that happens in object relations; similarly, psychotrauma is in
cluded in recent concepts of borderline personality disorders. In his
first description of trauma-forced internalization (introjection and i
dentification with the aggressor), Ferenczi has laid the foundation fo
r understanding how external trauma changes into autoaggressive sympto
matology and acting-out. Implantation of external violence is followed
by its introjection, including the creation of a malignant heterogene
ous introject, which now functions as a self-destructive internal forc
e, causing feelings of guilt and worthlessness. The introject is also
responsible for splitting and dissociation phenomena. The tension betw
een introject and the other parts of the self can be reduced by assimi
lating identification. Different kinds of trauma are: physical and psy
chic maltreatment, sexual abuse, unmastered severe losses, emotional d
eprivation (especially in early childhood), and unsolved real guilt. T
ransgenerational transmission of trauma forms introjects in the follow
ing generations. The function of the autoaggressive symptom can be und
erstood as a creation of an object surrogate, which corresponds to the
former traumatic object. In therapy one cannot expect that it will al
ways be possible to bring all the traumatic destruction into the trans
ference relationship.
