Complex post-traumatic stress disorder (CPTSD, cPTSD, or hyphenated C-PTSD) is a stress-related mental disorder generally occurring in response to complex traumas (i.e., commonly prolonged or repetitive exposure to a traumatic event (or traumatic events), from which one sees little or no chance to escape).
In the ICD-11 classification, C-PTSD is a category of post-traumatic stress disorder (PTSD) with three additional clusters of significant symptoms: emotional dysregulation, negative self-beliefs (e.g., shame, guilt, failure for wrong reasons), and interpersonal difficulties. C-PTSD's symptoms include prolonged feelings of terror, worthlessness, helplessness, distortions in identity or sense of self, and hypervigilance. Although early descriptions of C-PTSD specified the type of trauma (i.e., prolonged, repetitive), in the ICD-11 there is no requirement of a specific trauma type.
