- The DES score is the average of all the questions, so the minimum score is 0 and the maximum score is 100.[2] To calculate this yourself, all the questions are scored by dropping the zero on the percentage of each answer, e.g., 30% = 3; 80% = 8, these numbers are then added up. The total is then multiplied by 10 and divided by 28 (the number of questions) to calculate your average score.
- High and Low DES Scores High levels of dissociation are indicated by scores of 30 or more, scores under 30 indicate low levels. [1]:22 Successful treatment of a dissociative disorder should reduce the DES score when compared to the result before treatment began. [1]:23 Very high scores do not necessarily mean a more severe dissociative disorder is present, this is because the scale measures both normal and pathological dissociation.[1]:18
- Dissociative Identity Disorder and the DES Only 1% of people with Dissociative Identity Disorder have been found to have a DES score below 30. A very high number of people who score above 30 have been shown to have Posttraumatic Stress Disorder or a dissociative disorder other than Dissociative Identity Disorder.
- Clinical Uses of the Dissociative Experiences Scale If a person scores in the high range (above 30) then the DES questions can be used as the basis for a clinical interview, with the clinician asking the client to describe examples of the experiences they have had for any questions about experiences which occur 20% of the time or more. Alternatively, the Dissociative Disorders Interview Schedule (DDIS) or Structured Clinical Interview for Dissociative Disorders (SCID-D) can be used to reach a diagnosis.
