This is one of the first studies examining how demographic characteristics (gender, sexual orientation), personality traits (Dark Tetrad), and attitudes (aggrieved entitlement, sexual entitlement, sexual image abuse myth acceptance) relate to the likelihood of non-consensual intimate image dissemination perpetration or victimization. In a sample of 816 undergraduate students (72.7% female and 23.3% male), approximately 15% of them had at some point in their life, engaged in such behaviors and 1 in 3 had experienced this form of Image-based sexual abuse (IBSA) victimization. Higher psychopathy or narcissism scores were associated with an increased likelihood of having engaged in IBSA perpetration. Those with no history of victimization were 70% less likely to have engaged in IBSA perpetration compared to those who had experienced someone disseminating their intimate image without consent themselves. The challenges surrounding IBSA policy and legislation highlight the importance of understanding the factors and motivators associated with IBSA perpetration.
