Traumatic invalidation is defined as extreme or repetitive invalidation of a person's significant experiences, characteristics, and reactions (Linehan, 2015). This 1.5 hour webinar provides a deeper dive into a specific form of traumatic invalidation that is based on race. Race-based traumatic invalidation can take many forms and may involve direct exposure (e.g. personally experiencing racial discrimination), vicarious exposure (e.g., seeing police killings of Black people), and cumulative exposure (e.g. repeated microaggressions). Although some race-based traumatic events meet Criterion A for PTSD (e.g., racially motivated physical assaults), most race-based traumatic experiences do not (e.g., verbal harassment and discrimination), but can nonetheless lead to clinically significant and impairing PTSD symptoms. This webinar defines race-based traumatic invalidation and discusses how to effectively assess and treat this form of traumatic invalidation within the framework of DBT PE. Various case examples are provided to illustrate how to work with clients who have experienced race-based traumatic invalidation, with consideration for how to help clients cope with an ongoing invalidating environment in which racism is likely to persist. Finally, the importance of practicing cultural humility when working with clients who have experienced race-based traumatic invalidation, including attending to the unique location perspectives of the therapist and client, are discussed.
