The Dissociative Subtype of PTSD Author(s):

Ruth Lanius, MD, PhD


DSM-5 includes a dissociative subtype of PTSD focusing on symptoms of depersonalization and derealization. This subtype is present in 14-30% of PTSD patients and has been associated with high trauma exposure, childhood adversities, childhood onset of PTSD, greater re-experiencing, and suicidality.

This course describes a defense cascade model of dissociation to illustrate the etiology and mechanisms underlying symptomatology.

Clinicians can use information in this course for psychoeducation. This course includes case examples to discuss assessment of dissociative symptomatology and describe targeted treatment interventions.

Goals and Objectives

  1. Gain a greater understanding of the etiology and mechanisms underlying the dissociative subtype of PTSD
