Depersonalization-derealization disorder is characterized by feelings of detachment from the self (depersonalization) and/or from the world around (derealization). These experiences can be distressing, disorienting, and impair one's ability to function. Drawing on recognized diagnostic frameworks (DSM-5 and ICD-11) this symptom checklist supports clinicians and clients in recognising whether such experiences may warrant further assessment. It is not intended to provide a diagnosis or assess severity, but it can support early discussions about whether further evaluation is warranted.
Depersonalization and derealization are frequently under-recognized and misunderstood. This tool helps clinicians and clients explore these experiences in a safe, structured way:
For clients experiencing persistent feelings of detachment from self or surroundings.
For individuals whose anxiety symptoms include episodes of unreality or emotional numbing.
Gently introduce the possibility of depersonalization and derealization using the suggested therapeutic prompt.
Review the checklist collaboratively to clarify the nature and frequency of symptoms.
Consider the client's responses in the context of diagnostic frameworks and functional impact.
Use insights from the discussion to inform further steps such as assessment, psychoeducation, or formulation.
Depersonalization involves a sense of detachment from one’s own thoughts, emotions, or body — feeling like an outside observer or as though the self is unreal. Derealization involves perceiving the external world as distant, lifeless, or distorted. These experiences are not uncommon, with prevalence estimates suggesting they affect between 1–2% of the population.
This symptom checklist is informed by both DSM-5 and ICD-11 criteria. It is not intended to provide a formal diagnosis or assess severity but may support early recognition and therapeutic exploration. Clinicians can use it to validate a client’s experiences and facilitate conversations that may lead to further assessment.
