Summary

The study examines depersonalization and derealization symptoms in posttraumatic stress disorder (PTSD). It explores the cross-cultural validity of diagnosing these dissociative symptoms globally.

Area of Science:

Psychiatry
Psychology
Trauma Studies

Background:

Depersonalization and derealization are recognized as symptoms of dissociative disorders since DSM-III and included as a subtype of PTSD in DSM-5.
Chronic dissociative disorders are diagnosed differently across regions, with North America and Europe recognizing them, while Argentina utilizes the concept of hysteria.
The historical and clinical features of dissociative disorders are closely linked to hysteria, which is classified under dissociative disorders in ICD-10.

Purpose of the Study:

To investigate the cross-cultural validity of the dissociative subtype of PTSD.
To explore the differing diagnostic approaches to chronic dissociative symptoms like depersonalization and derealization globally.
To understand the influence of historical theories (Janet, Freud) on the conceptualization and treatment of dissociative disorders.

Main Methods:

Comparative analysis of diagnostic criteria and practices for dissociative disorders across different cultural contexts (North America, Canada, Europe, Argentina).
Review of historical and theoretical frameworks (Janet, Freud) related to trauma, dissociation, and hysteria.
Examination of the DSM-5 inclusion of a specific dissociative subtype for PTSD.

Main Results:

The inclusion of a specific dissociative subtype in DSM-5 aims to standardize the diagnosis of depersonalization and derealization in PTSD.
Cultural differences in diagnosing chronic dissociative disorders exist, with some regions favoring the term 'hysteria' over formal dissociative disorder diagnoses.
Theoretical underpinnings from figures like Janet and Freud significantly influence the understanding and therapeutic approaches to dissociation.

Conclusions:

The authors of the PTSD dissociative subtype are seeking to establish a globally applicable diagnostic construct.
Understanding the cultural variations in diagnosing dissociative disorders is crucial for achieving cross-cultural validity.
The historical connection between dissociation and hysteria continues to impact diagnostic practices in different parts of the world.
