Unlike other forms of psychological disorders, the core issue in trauma is reality.

The scientific study of suffering inevitably raises questions of causation, and with these, issues of blame and responsibility. Historically, doctors have highlighted predisposing vulnerability factors for developing PTSD, at the expense of recognizing the reality of their patients' experiences… This search for predisposing factors probably had its origins in the need to deny that all people can be stressed beyond endurance, rather than in solid scientific data; until recently such data were simply not available… When the issue of causation becomes a legitimate area of investigation, one is inevitably confronted with issues of man's inhumanity to man, with carelessness and callousness, with abrogation of responsibility, with manipulation and with failures to protect.

It is indeed the truth of the traumatic experience that forms the center of its psychopathology; it is not a pathology of falsehood or displacement of meaning, but of history itself” (p. 5)

Dissociation is adaptive: it allows relatively normal functioning for the duration of the traumatic event and then leaves a large part of the personality unaffected by the trauma.

Beneath the surface of the protective parts of trauma survivors there exists an undamaged essence, a Self that is confident, curious, and calm, a Self that has been sheltered from destruction by the various protectors that have emerged in their efforts to ensure survival. Once those protectors trust that it is safe to separate, the Self will spontaneously emerge, and the parts can be enlisted in the healing process

Eighty two percent of the traumatized children seen in the National Child Traumatic Stress Network do not meet diagnostic criteria for PTSD.15 Because they often are shut down, suspicious, or aggressive they now receive pseudoscientific diagnoses such as “oppositional defiant disorder,” meaning “This kid hates my guts and won’t do anything I tell him to do,” or “disruptive mood dysregulation disorder,” meaning he has temper tantrums. Having as many problems as they do, these kids accumulate numerous diagnoses over time. Before they reach their twenties, many patients have been given four, five, six, or more of these impressive but meaningless labels. If they receive treatment at all, they get whatever is being promulgated as the method of management du jour: medications, behavioral modification, or exposure therapy. These rarely work and often cause more damage.
