Dissociative Experiences Scale – II
The DES-II is a 28-item, self-report measure of dissociative experiences. Dissociation is often considered a psychological defence mechanism for victims of traumatising events, and the scale is of particular use in measuring dissociation among people with PTSD, dissociative disorders, borderline personality disorder and those with a history of abuse.
More broadly, dissociative symptoms can be considered as a transdiagnostic indicator of dysfunctional coping, with many disorders being associated with higher than average dissociation. The scale can be used during the course of treatment to track progress over time.
The DES has three sub-scales:
- Amnesia Factor
- Depersonalisation / Derealisation Factor
- Absorption Factor
