The Cambridge Depersonalisation Scale (CDS) is a widely used, validated self-report instrument that captures the frequency and duration of depersonalization and derealization symptoms. Originally developed by Sierra and Berrios, it allows clinicians to evaluate the subjective and often distressing experiences of detachment from self, body, and surroundings. Because dissociative symptoms can occur across various mental health conditions—such as anxiety, trauma-related disorders, and mood disorders—a repeatable, standardized measure provides crucial clarity when mapping a patient's presentation.
By explicitly differentiating the frequency of symptoms from their typical duration, the CDS offers a nuanced clinical picture of how depersonalization impacts daily functioning. This granular approach helps clinicians track symptom fluctuations over time, establish an evidence-based baseline, and structure psychoeducation around the specific facets of the dissociative experience, from emotional numbing to anomalous body perception. Weaving the CDS into an assessment protocol like Depersonalization-Derealization: PDF Worksheet, Tools and Exercises can strengthen the shared understanding of these often hard-to-describe phenomena.

Overall score
152/ 290
29-item self-report questionnaire assessing the frequency and duration of depersonalization and derealization experiences occurring over the past 6 months. It explores a broad range of phenomena: feelings of unreality or self-estrangement, detachment from the body, emotional numbing, alterations in the perception of the external world, distortions in the experience of time and memory, feeling of being an outside observer of one's own actions or thoughts. Benchmark instrument for screening and monitoring depersonalization/derealization disorder as well as dissociative symptoms in other disorders (anxiety, trauma, temporal lobe epilepsy, substance-induced effects).

What the test measures
The CDS captures the multidimensional nature of depersonalization and derealization experiences. It breaks down the overarching sense of unreality into four core clinical facets, allowing clinicians to pinpoint which aspects of dissociation are most prominent, often complementing a broader assessment of Exploring Your Anxiety Experience.
- Anomalous body experience: Feeling detached from one's physical body, lacking agency over movements, or experiencing distorted somatic perceptions.
- Emotional numbing: A marked absence of emotional reactivity, a loss of affection, or a blunted capacity for pleasure and distress.
- Alienation from surroundings: Derealization symptoms where the environment feels flat, lifeless, or as if separated by a veil.
- Anomalous subjective recall: Distortions in the subjective experience of time and memory, such as feeling disconnected from one's own past or experiencing déjà vu.
This instrument is intended for adult patients presenting with dissociative symptoms, whether as a primary concern or in the context of broader psychological difficulties such as severe anxiety or trauma.
When and why to use it
Clinicians integrate the CDS into their practice to objectify symptoms that patients often struggle to articulate. It is particularly valuable for mapping the nuances of a dissociative presentation and guiding targeted interventions.
- Intake and baseline assessment: To establish a comprehensive profile of dissociative symptoms when a patient presents with complaints of feeling unreal or numb.
- Differential support: To help distinguish primary depersonalization from dissociative symptoms secondary to acute stress, panic attacks, or Generalized Anxiety Disorder (GAD).
- Monitoring treatment progress: To track changes in symptom frequency and duration over the course of therapy, providing tangible evidence of improvement.
- Psychoeducation anchor: To validate the patient's experience by showing them that their frightening symptoms are recognized phenomena, which pairs well with tools like a Friendly Formulation.
Using a validated score adds precision over clinical impression alone by formally quantifying both how often symptoms occur and how long they persist, ensuring that subtle shifts in the patient's condition are not missed.

The questions
- This questionnaire describes strange experiences that may occur in healthy individuals as well as in those who seek help for psychological difficulties. We would like to know to what extent you have had these experiences OVER THE PAST 6 MONTHS. For each item, please indicate the FREQUENCY with which you have experienced it and its usual DURATION. If you are not sure, give your best guess. If the experience has never happened to you, check 'Never' (the duration question does not apply).1. For no apparent reason, I feel strange, as if I'm not real or as if I'm cut off from the world.Probes the sudden onset of profound detachment from reality and the self.
