“DARVO is an acronym for “deny, attack, and reverse victim and offender”. It refers to a reaction that alleged perpetrators of wrongdoing, particularly sexual offenders, may display in response to being held accountable for their behavior. Some researchers and advocates have indicated that it can be as a common manipulation strategy of psychological abusers. An abuser (or alleged abuser) denies the abuse ever took place, attacks the person that alleged abuse (often the victim) for attempting to hold the abuser (or alleged abuser) accountable for their actions, and claims that they are actually the victim in the situation, thus reversing what may be a reality of victim and offender. It often involves not just “playing the victim” but also victim blaming.-Wikipedia contributors, “DARVO,” Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/w/index.php?title=DARVO&oldid=1100548671 (accessed August 11, 2022).
