Studies on the prevalence of DARVO suggest it is a common tactic used by perpetrators when they are confronted over their behavior, regardless of the type of harm they have caused. One study of undergraduates who had confronted someone over a harmful event found that DARVO was used by 72% of the perpetrators during the confrontation. The offenses ranged from social mistreatment, like betrayed secrets, to interpersonal violence, like
sexual assault or
child abuse. DARVO is particularly likely in cases of sexual violence, with one study of women who had been sexually assaulted at university reporting that half of the perpetrators involved had used elements of DARVO in later conversations. DARVO has been studied and documented in specific contexts beyond those of interpersonal violence. DARVO has been labeled in some cases of
medical malpractice, where victim blaming is already common since doctors and hospitals generally refuse to admit their mistakes due to
legal risk. DARVO has also been cited as common in
workplace bullying and
toxic workplace culture. In the case of academia, when professors try to report bullying, DARVO tactics often compel them to stop speaking up, adding to their
trauma and contributing to a
culture of silence. In this vein, DARVO has been theorized as acting on groups of people and not just individuals. One case under study was the intense backlash to the
MeToo movement, where
men's rights activists said some MeToo allegations were false and launched a
HimToo movement. Other researchers say DARVO can happen at even wider societal levels, labeling it as DARVO when media organizations promote
rape myths in efforts to discredit sexual assault victims. Researchers have also drawn parallels between individual DARVO tactics and the tendency for dominant cultural groups to stigmatize and blame groups who are speaking up about their trauma. ==Effectiveness==
