This article, based on a comprehensive review by Weathers and associates, provides a selective and brief summary of trauma and PTSD assessments in adults.

Posttraumatic stress disorder (PTSD) is a severe and often chronic anxiety disorder that can develop following exposure to an event involving actual or perceived threat to the life or physical integrity of oneself or another person.

Thus, trauma and PTSD are significant mental health problems.
