DES Score Interpreter

Warrants clinical evaluation

Scores ≥30 are associated with significant dissociative pathology. A score at this level warrants a structured clinical evaluation by a qualified mental health professional.

28 items each rated 0–100% in 10% steps; score is the mean of all 28 items (not a sum). Higher scores indicate more frequent dissociative experiences.

Dissociation tests measure detachment from thoughts, feelings, or identity. The DES (Dissociative Experiences Scale) is the criterion-standard 28-item measure: mean score 0–100; ≥30 warrants clinical evaluation for dissociative disorder. Developed by Bernstein & Putnam (1986); the ≥30 screening threshold was validated by Carlson et al. (1993).

What Does a Dissociation Test Measure?

Dissociation is a psychological experience in which a person becomes detached from their thoughts, feelings, memories, sense of identity, or surroundings. Mild dissociation is common in everyday life (daydreaming, highway hypnosis, absorption in a book). Pathological dissociation, especially when frequent and distressing, is associated with trauma exposure, PTSD, and dissociative disorders including dissociative identity disorder (DID) and depersonalization/derealization disorder (DPDR).

A dissociation test quantifies the frequency of dissociative experiences across three clusters: amnesia (gaps in memory or recall), depersonalization and derealization (feeling detached from one's body or surroundings), and absorption and imaginative involvement (intense focus that limits awareness of surroundings). The most widely used dissociation test is the DES (Dissociative Experiences Scale), a 28-item validated self-report measure developed by Bernstein and Putnam (1986).

Each DES item asks how often (0% to 100%, in 10% intervals) a person experiences a specific dissociative phenomenon. The mean score across all 28 items is computed as the total score (0–100). In the Carlson et al. (1993) multicenter study of 1,051 subjects, a mean score of 30 or higher yielded 76% sensitivity and 76–85% specificity for dissociative identity disorder, and was confirmed as an appropriate first-line screening threshold warranting further clinical evaluation. The DES-T (Taxon) is an 8-item subscale specifically linked to pathological dissociation.

The DES is in the public domain and free for clinical and research use. It has been used in over 1,000 published studies and is endorsed by the International Society for the Study of Trauma and Dissociation (ISSTD) as a first-line screening scale for dissociative disorders.

DES Score Interpretation

Carlson EB et al. (1993). Mean score = sum of all 28 item scores ÷ 28. Each item rated 0–100% in 10% steps. DES-T (Taxon) is an 8-item subscale that specifically identifies pathological dissociation; Waller & Ross (1997) estimated that approximately 3.3% of the general population belongs to the pathological dissociative taxon captured by the DES-T.

Types of Dissociative Experiences

The DES captures three distinct types of dissociative experience, corresponding to the scale's empirically derived subscales (Bernstein & Putnam, 1986; Dubester & Braun, 1995):

TypeWhat It InvolvesExample Experiences
AmnesiaGaps in autobiographical memory or awareness of recent eventsFinding yourself somewhere with no memory of how you got there; discovering you did something you have no recollection of
Depersonalization / DerealizationFeeling detached from one's body, thoughts, or surroundingsWatching yourself from outside your body; feeling that familiar places look strange or unreal
AbsorptionIntense attentional focus that excludes awareness of other stimuliBecoming so absorbed in a film or daydream that time disappears; not noticing pain or someone speaking to you

These three subscales show different patterns across diagnostic groups. Dubester & Braun (1995) reported subscale test-retest reliabilities of .95 (amnesia), .89 (depersonalization/derealization), and .82 (absorption) in a clinical sample, supporting the stability of each domain over time.

Pathological dissociation — primarily high amnesia scores — is most closely associated with severe trauma histories and dissociative disorders. Absorption, by contrast, also occurs at elevated levels in hypnotically talented non-clinical individuals and is not on its own a strong indicator of psychopathology.

Frequently Asked Questions

What does a DES score of 30 or higher mean?

A mean DES score of 30 or higher is a widely used clinical screening threshold indicating that further evaluation for a dissociative disorder is warranted. It does not constitute a diagnosis. In the Carlson et al. (1993) multicenter study, this cutoff yielded 76% sensitivity and 76–85% specificity for dissociative identity disorder.

Is the DES self-report or clinician-administered?

The DES is a self-report questionnaire. Respondents rate how often (0% to 100%, in 10% increments) they experience each of 28 dissociative phenomena. It typically takes 10–15 minutes to complete and requires no clinician involvement for administration, though interpretation should involve a trained clinician.

Can the DES diagnose dissociative identity disorder?

No. The DES is a screening instrument, not a diagnostic tool. A high score indicates that a structured clinical interview — such as the SCID-D — is appropriate. In the Carlson et al. (1993) multicenter study, only about 17% of those scoring ≥30 actually had dissociative identity disorder, highlighting the importance of confirmatory interview-based assessment.

What are the three subscales of the DES?

The DES yields three subscale scores: amnesia (lapses in memory or recall), depersonalization/derealization (feeling detached from one's body or surroundings), and absorption (intense attentional focus that limits awareness of other stimuli). Dubester & Braun (1995) reported test-retest reliabilities of .95, .89, and .82 for these three subscales, respectively.
