This 1.5 hour webinar provides an introduction to the concept of moral injury, which involves perpetrating, failing to prevent, or witnessing acts that are inconsistent with deeply held values and moral beliefs. Moral injury may result from engaging in behaviors that harmed other people (e.g., sexual or physical assault) and/or failing to act to prevent harm to others (e.g., not protecting children from abuse). Although moral injury has often been researched in the context of military service, it can occur in many other types of traumatic or highly stressful situations. For example, people may engage in morally injurious behaviors in response to their own experiences of abuse. Individuals who have experienced moral injury often have posttraumatic stress disorder (PTSD), intense guilt and shame, are unable to forgive themselves, feel strongly that they deserve to suffer indefinitely, and are at high risk for suicide. In this webinar, examples of moral injury as well as common outcomes of these experiences are described. In addition, strategies for treating PTSD related to moral injury are discussed that are derived from the DBT Prolonged Exposure protocol for PTSD.
