The Vicarious Trauma Toolkit (VTT) was developed on the premise that exposure to the traumatic experiences of other people—known as vicarious trauma—is an inevitable occupational challenge for the fields of victim services, emergency medical services, fire services, law enforcement, and other allied professionals; however, organizations can mitigate the potentially negative effects of trauma exposure by becoming vicarious trauma-informed. The VTT includes tools and resources tailored specifically to these fields that provide the knowledge and skills necessary for organizations to address the vicarious trauma needs of their staff.
