Complex post-traumatic stress disorder (C-PTSD; also known as complex trauma disorder) is a psychological disorder that can develop in response to prolonged, repeated experience of interpersonal trauma in a context in which the individual has little or no chance of escape. C-PTSD relates to the trauma model of mental disorders and is associated with chronic sexual, psychological, and physical abuse or neglect, chronic intimate partner violence, victims of prolonged workplace or school bullying, victims of kidnapping and hostage situations, indentured servants, victims of slavery and human trafficking, sweatshop workers, prisoners of war, concentration camp survivors, residential school survivors, prisoners kept in solitary confinement for a long period of time, and defectors from authoritarian religions. It is most often directed at children and emotionally vulnerable adults, and whilst motivations behind such abuse vary, though mostly being predominantly malicious, it has also been shown that the motivations behind such abuse can be well-intentioned. Situations involving captivity/entrapment (a situation lacking a viable escape route for the victim or a perception of such) can lead to C-PTSD-like symptoms, which can include prolonged feelings of terror, worthlessness, helplessness, and deformation of one's identity and sense of self.
