Post-traumatic stress disorder (PTSD) is an anxiety disorder that consists of a sustained and dysfunctional emotional reaction to an extreme stressor. Factors related to risk of developing chronic disturbance may be divided into three types: pretrauma factors, factors related to the trauma itself, and post-trauma factors. The authors review research relevant to each of these factors.
