The PTSD Criterion A debate: A brief history, current status, and recommendations for moving forward

Abstract

AbstractPosttraumatic stress disorder (PTSD) Criterion A, also known as the “stressor criterion,” has been a major source of debate ever since PTSD was added to the third edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM) in 1980. Since then, the traumatic stress field has held an ongoing debate about how to best define Criterion A and the events that it covers. Because of the COVID‐19 pandemic and recent race‐based incidents, the Criterion A debate has been reinvigorated. In this paper, we review briefly the history of Criterion A and changes in its language across different editions of the DSM. We then describe the four main positions held by scholars involved in the Criterion A debate and carefully examine the support for those positions. We conclude by offering recommendations for moving forward.
