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 and neglect, chronic intimate partner violence, victims of kidnapping and hostage situations, indentured servants, victims of slavery and human trafficking, sweatshop workers, prisoners of war, concentration camp survivors and defectors of cults or cult-like organizations. 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. C-PTSD has also been referred to as DESNOS or Disorders of Extreme Stress Not Otherwise Specified.'history of exposure to early life developmentally adverse interpersonal trauma such as sexual abuse, physical abuse, violence, traumatic losses of other significant disruption or betrayal of the child's relationships with primary caregivers, which has been postulated as an etiological basis for complex traumatic stress disorders. Diagnosis, treatment planning and outcome are always relational.'

C-PTSD has also been referred to as DESNOS or Disorders of Extreme Stress Not Otherwise Specified. Some researchers believe that C-PTSD is distinct from, but similar to, PTSD, somatization disorder, dissociative identity disorder, and borderline personality disorder. Its main distinctions are a distortion of the person's core identity and significant emotional dysregulation. It was first described in 1992 by Judith Herman in her book Trauma & Recovery and in an accompanying article. The disorder is included in the draft version of the World Health Organization's (WHO) International Statistical Classification of Diseases and Related Health Problems, 11th Edition (ICD-11) which is still in the approval process. This category of PTSD is not yet adopted by the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5). The diagnosis of PTSD was originally developed for adults who had suffered from a single event trauma, such as rape, or a traumatic experience during a war. However, the situation for many children is quite different. Children can suffer chronic trauma such as maltreatment, family violence, and a disruption in attachment to their primary caregiver. In many cases, it is the child's caregiver who caused the trauma. The diagnosis of PTSD does not take into account how the developmental stages of children may affect their symptoms and how trauma can affect a child’s development. The term developmental trauma disorder (DTD) has been proposed as the childhood equivalent of C-PTSD. This developmental form of trauma places children at risk for developing psychiatric and medical disorders. Bessel van der Kolk explains DTD as numerous encounters with interpersonal trauma such as physical assault, sexual assault, violence or death. It can also be brought on by subjective events such as betrayal, defeat or shame. Repeated traumatization during childhood leads to symptoms that differ from those described for PTSD. Cook and others describe symptoms and behavioural characteristics in seven domains: Adults with C-PTSD have sometimes experienced prolonged interpersonal traumatization beginning in childhood, rather than, or as well as, in adulthood. These early injuries interrupt the development of a robust sense of self and of others. Because physical and emotional pain or neglect was often inflicted by attachment figures such as caregivers or older siblings, these individuals may develop a sense that they are fundamentally flawed and that others cannot be relied upon. This can become a pervasive way of relating to others in adult life, described as insecure attachment. This symptom is neither included in the diagnosis of dissociative disorder nor in that of PTSD in the current DSM-5 (2013). Individuals with Complex PTSD also demonstrate lasting personality disturbances with a significant risk of revictimization. Six clusters of symptoms have been suggested for diagnosis of C-PTSD: Experiences in these areas may include: C-PTSD was under consideration for inclusion in the DSM-IV but was not included when the DSM-IV was published in 1994. Neither was it included in the DSM-5. PTSD continues to be listed as a disorder.
