Jennifer Joy Freyd (; born October 16, 1957, in Providence, Rhode Island) is an American researcher, scholar, and psychologist.
Freyd is a Professor of Psychology at the University of Oregon and principal investigator of the Freyd Dynamics Lab.
She is also currently a visiting scholar at the Center for Advanced Study in the Behavioral Sciences at Stanford University (2018–2019).Freyd became known for introducing the concept betrayal trauma and establishing the term DARVO.
In 1996, Freyd expanded upon literature exploring psychogenic amnesia and child sexual abuse by capturing the nuance of betrayal in a two-dimensional model of traumatic events.
Since betrayal trauma is defined as a violation perpetrated by someone with whom the victim is close to and reliant upon for support and survival, Freyd's model detailed the extent to which a traumatic event is defined by betrayal trauma as it occurs across dimensions of low-to-high and in its degree of social betrayal and/or the extent of terror/fear induced by the event.
