Depersonalization-Derealization: PDF Worksheet, Tools and Exercises

Patients presenting with depersonalization-derealization disorder often arrive with a paradox already articulated: they describe their experience precisely ("I'm watching my life instead of living it") and yet remain convinced they are losing their mind. This fiche PDF gives you a structured visual support to use in session the moment that phenomenology surfaces, so you can name the condition, map the differential, and establish a shared clinical vocabulary before the fear loop consolidates further.

Why DPDR Resists Oral Explanation

The core difficulty is structural. Reality testing stays intact in DPDR, which means the patient already "knows" the world is real, and that knowledge offers zero relief. Every verbal reassurance you offer triggers an immediate self-checking loop: the patient tests for the feeling, fails to find it, and amplifies the hypervigilance that maintains the symptom. That loop is one reason DPDR is chronically under-identified: the patient appears insight-intact, so clinicians sometimes move past the phenomenology before fully naming it.

The differential is equally hard to convey in words alone. Patients routinely fear they are entering psychosis, experiencing panic disorder, or reliving a traumatic intrusion. Untangling those distinctions verbally eats session time and often leaves the patient with a partial, distorted map of their own condition. A visual support settles the question more cleanly, in less time.

Safety behaviours compound maintenance further: mirror avoidance, repeated reassurance-seeking, reality-testing dozens of times a day. These map directly onto the CBT maintaining processes model, and avoidance reduction is an explicit target, but a patient who has never heard the term "safety behaviour" needs to see the loop before they can engage with disrupting it.

What the Fiche Contains: A Visual Support for In-Session Explanation

The fiche is built around five content panels plus a dedicated clinical debrief section. Panel 1, "The two faces of unreality," arranges depersonalization and derealization in a parallel side-by-side layout, with specific phenomenological descriptors under each column ("hands don't feel like yours," "surroundings look foggy, flat," "loved ones look like actors"). The visual separation does something oral explanation cannot: it shows the patient exactly where their experience sits within a named taxonomy, anchored to ICD-11 code 6B66, without pathologising the encounter.

Panel 3 draws the clinically decisive line between a transient episode and a diagnosable disorder, grounding the distinction in functional impairment rather than symptom count. Panel 4, "What it is NOT," covers four differential exclusions in parallel blocks: not psychosis, not primary panic, not a PTSD flashback, not substance-induced unreality. Patients can return to this panel between sessions, which reduces the demand for repeated reassurance in subsequent appointments.

Panel 5 introduces six self-management directions: naming the symptom to break the fear loop, redirecting attention outward rather than inward, dropping safety behaviours, sensory grounding, addressing upstream load (sleep disruption, cannabis, chronic anxiety), and seeking DPDR-specific CBT through the dedicated CBT resource on depersonalization. Each direction is stated in a single line, which suits patients whose attentional resources are already taxed by the disorder.

The closing "To discuss in session" block offers three structured prompts: trigger mapping, safety behaviour inventory, and criteria for CBT referral. This section is yours to use as a clinical scaffold, not a patient homework assignment.

> To remember: this fiche is a visual support that facilitates in-session explanation, not a self-report questionnaire. Its value lies in what it lets you show while you speak; the patient leaves with a concrete reference map, not a task to complete alone.

When and How to Introduce the Fiche

The fiche fits naturally in the first or second session once the phenomenology has emerged, before the differential is fully closed. It works particularly well with patients who present with marked health anxiety (see the Health Anxiety resource) or a history of unusual perceptual experiences that have never been properly labelled.

A low-stigma introduction works best: "I'd like to show you a map of what you've been describing, so we have a common language for it." Walk through Panel 4 together before handing the fiche over; patients who read the psychosis distinction without contextual framing can misread it in both directions.

For debrief, ask which descriptors in Panel 1 fit their experience most precisely and which do not. That small calibration task serves diagnostic refinement and the therapeutic alliance simultaneously. If safety behaviours surface during Panel 4, the fiche pairs naturally with grounding technique resources and a deeper look at psychological safety crutches in subsequent sessions.

One clear limit: when active substance use is the primary driver of unreality, the fiche itself states that pathway requires separate management. Address the substance before building the DPDR psychoeducation arc.

The fiche does not replace formulation. It makes the explanation sharper and leaves the patient with a reference they can reach for when the filter descends again between appointments.
