Sexual violence (including sexual assault and sexual harassment) occurs frequently and can cause substantial harm. Sexual violence is often experienced in the context of an institution (such as a university); our research indicates that associated institutional behaviors can harm or help. In this presentation I will present concepts and research related to these issues: betrayal trauma theory & betrayal blindness, DARVO (Deny, Attack, & Reverse Victim & Offender; a harmful perpetrator response to disclosure), institutional betrayal, and institutional courage. I will conclude by offering concrete steps that individuals and institutions can take to respond well to disclosures and to address sexual harassment and promote institutional courage.
