What is the DES-B used for?

The DES-B is used to measure how often an adult experiences dissociative symptoms, such as feeling detached from their body or surroundings. Clinicians use it to screen for dissociation, rate symptom severity, and track change over time, most often in mental health, trauma, and integrated care settings.

How many questions is the DES-B?

The DES-B has eight items. Each asks how frequently a specific dissociative experience occurred over the past week, rated from 0 (not at all) to 4 (more than once a day). The full questionnaire takes most adults about two to four minutes to complete.

How is the DES-B scored?

Sum the eight item ratings for a raw total from 0 to 32, where higher scores reflect more frequent symptoms. The DSM-5 field trials also used an average score, the total divided by items answered, to rate severity from none to extreme on a 0 to 4 scale.

Does the DES-B diagnose a dissociative disorder?

No. The DES-B measures the frequency and severity of dissociative symptoms, but it does not diagnose a dissociative disorder. It has no diagnostic cutoff. Use the score to guide clinical decision-making and to decide whether a fuller assessment or clinical interview is warranted.

Is the DES-B free to use?

The DES-B is distributed by the American Psychiatric Association as a DSM-5 emerging measure and can be reproduced for clinical and research use without charge. Always confirm the current permitted-use terms with the American Psychiatric Association before adopting it in your practice.

How often should the DES-B be given?

There is no fixed schedule, but the DES-B was designed for repeated use, and weekly administration is common. Giving it on a regular cadence lets you compare scores over time and see whether dissociative symptoms are improving or worsening, rather than relying on a single measurement.

DES-B Dissociation Scale | Template & auto-scoring

The Brief Dissociative Experiences Scale (DES-B) is an 8-item self-report questionnaire that measures how often an adult has experienced dissociative symptoms, such as feeling detached from the body or surroundings, over the past seven days. Modified for the DSM-5 field trials, it rates each experience on a 0 to 4 frequency scale and supports both screening and ongoing symptom monitoring.

Why healthcare providers use the DES-B

Brief and low burden. Eight items take about two to four minutes to complete, so it fits easily into a busy intake or visit.
Standardized severity. A consistent 0 to 4 rating gives you a repeatable measure of dissociative symptoms across patients and across visits.
DSM-5 aligned. It was refined during the DSM-5 field trials as a measure of dissociation severity, giving it a recognized clinical basis.
Sensitive to change. Repeated administration lets you track whether symptoms are improving or worsening over time.

Which settings use the DES-B?

Outpatient mental health. Therapists and psychiatrists use it during assessment and ongoing care for trauma-related concerns.
Trauma and PTSD programs. Clinicians screen for dissociation alongside post-traumatic stress symptoms.
Integrated primary care. Behavioral health teams use it to flag dissociative symptoms that warrant closer assessment.

What does the DES-B measure?

The DES-B captures the frequency of common dissociative experiences over the past week. Rather than diagnosing a specific disorder, it quantifies how often symptoms occur so you can gauge severity and monitor change. Its items span several related domains:

Depersonalization. Feeling detached from your own body, thoughts, or emotions.
Derealization. Experiencing surroundings as unreal, dreamlike, or distant.
Memory and awareness gaps. Losing track of time or finding evidence of actions you do not recall.

Scoring the DES-B

Number of items: 8.
Per-item scale: 0 (not at all) to 4 (more than once a day).
Total score range: 0 to 32, summed across all eight items.
Score direction: higher scores indicate more frequent, more severe dissociative symptoms.

The DES-B has no diagnostic cutoff. During the DSM-5 field trials, clinicians found an average score, the raw total divided by the number of items answered, reliable and clinically useful for rating overall severity on a 0 to 4 scale. If three or more items are unanswered, do not calculate a score. Interpret results alongside clinical interview and history, not in isolation. The bands below reflect that average-score severity rating.

Average score	Interpretation	Suggested next step
0	None	Monitor
1	Mild	Monitor
2	Moderate	Consider further assessment
3	Severe	Consider further assessment
4	Extreme	Consider further assessment

Best practices for administration

Set a clear time frame. Remind patients that the items ask about the past seven days.
Offer privacy. Dissociative symptoms can feel distressing to report, so give patients a private, unhurried setting.
Use it repeatedly. Re-administer on a regular schedule, such as weekly, to track change rather than relying on a single score.
Pair with clinical judgment. Use the score to guide conversation and clinical decision-making, not to replace assessment.
Watch for missing items. If three or more items are skipped, do not calculate a total score.

How Zentake helps with the DES-B

Automatic scoring. Zentake totals every DES-B on submit, so there is no hand-tallying.
Longitudinal tracking. Re-send on a schedule and view change over time as symptoms shift.
Before the visit. Patients complete the DES-B from home on any device, so results are ready before the visit for mental health practices.
HIPAA compliant. Every response is encrypted, with a signed BAA available on every plan.

The DES-B was modified for the DSM-5 field trials by Constance Dalenberg and Eve Carlson, based on the Dissociative Experiences Scale. The American Psychiatric Association distributes it as a severity measure of dissociative symptoms for adults, which is also the source of the average-score severity guidance summarized above.
