A light lunch will be served. Abstract: Despite increased attention to campus sexual assault and efforts to improve university response systems (e.g., reporting procedures, resources), victimization remains a rampant problem on college campuses. Most sexual assaults are not reported, and few survivors seek help from victim services. In my work, I am curious how laws/policies created to address this problem (e.g., Title IX) shape institutional response systems and students’ perceptions and behaviors, and then, what barriers prevent survivors from using supports created by such policies. To answer these questions, I conducted two complementary studies of undergraduate resident assistants (RAs) and undergraduate women living in university housing (Residents). RAs are a critical group, as they are often first responders for students in crisis, but are also mandated to report sexual assault disclosures to the university. In one study, I examine how RAs’ knowledge and perceptions of reporting procedures predict their likelihood to report disclosures. In another, I examine the barriers that prevent Residents who had experienced sexual assault from using three supports on campus: formal reporting procedures, the sexual assault center, and housing staff. Together, these studies demonstrate ways that policies affect students—in particular, reporting and help seeking for sexual assault.
