Introduction On October 1, 2017, a lone gunman shot and killed 60 people and injured 867 others at the Route 91 Harvest Music Festival in Las Vegas, Nevada, making this mass shooting the deadliest in US history.1 Witnesses and survivors of mass violence incidents (MVIs) often experience depression and posttraumatic stress disorder (PTSD).2 However, the psychological sequelae and associated factors among witnesses and survivors of the Las Vegas MVI have yet to be examined.
