No laboratory test for depersonalization-derealization disorder currently exists. [11] As patients with dissociative disorders likely experienced intense trauma in the past, concomitant dissociative disorders should be considered in patients diagnosed with a stress disorder (i.e. PTSD or acute stress disorder). [50]
This classification is based on the findings that depersonalization and derealization are prevalent in other dissociative disorders including dissociative identity disorder. [ 6 ] Though degrees of depersonalization can happen to anyone who is subject to temporary anxiety or stress, chronic depersonalization is more related to individuals who ...
DES is intended to be a screening test, since only 17% of patients with scores over 30 will be diagnosed with having dissociative identity disorder. [2] Patients with lower scores above normal may have other post-traumatic conditions. The DES-II contains the same questions but with a different response scale. [3]
The more severe, long-lasting dissociative disorders are usually related to some physical, sexual, or psychological trauma, according to NAMI. Silhouette of young woman. Degrees of dissociation
Cause: While not as strongly linked as other dissociative disorders, there is a correlation between depersonalization-derealization disorder and childhood trauma, especially emotional abuse or neglect. It can also be caused by other forms of stress such as sudden death of a loved one.

Compared to other methods to assess the domain of dissociative identity disorder phenomena, MDI demonstrates internal reliability, temporal stability, convergent validity, discriminant validity, and construct validity. [7] [8] [3] Specifically, MDI exhibits incremental validity over the Dissociative Experiences Scale (DES). [4] [7] [8]
