Dissociative Experiences Scale

The Dissociative Experiences Scale (DES) is a psychological self-assessment questionnaire that measures dissociative symptoms. It contains twenty-eight questions and returns an overall score as well as four sub-scale results. 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. 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.
