Editorial: A Historical and Developmental Perspective on Posttraumatic Stress Disorder

In this issue of the Journal, Hitchcock and colleagues1 present the latest findings, documenting impairing posttraumatic symptomatology in this age group and extending previous research about developmentally appropriate criteria for PTSD. [...]the number of Cluster C (avoidance/numbing) signs was dropped from 3 to 1. Several disorders have had some initial research in this regard, but harking back to the model of PTSD-YC—in which detailed case studies and clinical observations led to diagnostic modifications, followed by systematic evaluation and further refinement, and ultimately, demonstration of a valid developmental subtype of a disorder—has much future promise beyond PTSD.
