DSM-5 Diagnostic Criteria for PTSD
The diagnostic criteria for posttraumatic stress disorder (PTSD) have evolved substantially since the disorder was introduced in DSM-III. The latest revision for DSM-5 involved several notable changes, including moving PTSD to a new chapter of trauma- and stressor-related disorders, reconceptualizing the stressor criterion, expanding from three to four symptom clusters, adding three new symptoms and revising others, adding a dissociative subtype, and creating separate criteria for children six years and younger. This chapter traces the evolution of the PTSD criteria and describes the DSM-5 criteria in detail. Since PTSD has been a controversial diagnosis since its inception, this chapter also provides an overview of the conceptual issues and empirical findings that influenced its development over time and motivated its current iteration.
