The prevalence of dissociative responding in Type I and Type II trauma survivors and in many disorders is high – between 15 and 30% of PTSD diagnoses could be of the PTSD/D subtype. Although all trauma responses can be formulated as dissociative theoretically, in practice there are two distinct presentations: reliving and flashbacks vs shutting down and freezing. Often the client presentation is a mix of these two types of symptoms.
