Loyalty to a more powerful abuser — in spite of the danger that this loyalty puts the victim in — is common among victims of domestic abuse battered partners and child abuse (dependent children). In many instances the victims choose to remain loyal to their abuser, and choose not to leave him or her, even when they are offered a safe placement in foster homes or safe houses. This unhealthy type of mental phenomenon is also known as Trauma-Bonding or Bonding-to-the-Perpetrator. This syndrome was described by psychoanalysts of the object relations theoryschool (see Fairbairn) as the phenomenon of psychological identification with the more powerful abuser. A variant of Stockholm Syndrome includes cases of abusive parents and abusive siblings in which the victim, even after entering adulthood, still justifies the family abuse.
