The consequences of the tragic school shooting on May 24, 2022 at Robb Elementary School in Uvalde, Texas will reverberate for decades to come. Trauma on this level affects the survivors and bystanders who directly witnessed tragedy unfold on the school campus, families, friends, and first responders, as well as entire communities and onlookers from communities far and wide. Consequences of this type of trauma can be devastating and often lead to posttraumatic stress disorder, depression, and a range of other psychological symptoms that can profoundly affect health, behavior, learning, and social relationships. Experts across the state and country can help by providing training and ongoing consultation to local community members and providers who will be delivering trauma-informed services in the immediate, intermediate, and long-term aftermath of the shooting. However, there will be a critical need to build from the ground up a long-term system of prevention support in the Uvalde community and surrounding communities. Funding will be essential and local mental health, healthcare, and education leaders must work together on how to roll out a long-term, sustainable trauma-informed community system of support.
