Background. Depersonalization has long been considered a syndrome but there is poor agreement on its constituent symptoms. Method. In order to establish whether different symptoms of depersonalization represent the expression of a single or several underlying dimensions, an exploratory factor analysis on the Cambridge Depersonalization Scale (CDS) was carried out on 138 consecutive patients diagnosed with depersonalization disorder. Results. Four well determined factors accounting for 73·3% of…

Depersonalization in Psychiatric Patients: A Transcultural Study
There is evidence suggesting that the prevalence of depersonalization in psychiatric patients can vary across cultures. To explore the possible influence of culture on the prevalence of
Mindfulness and Body Awareness in Depersonalization Disorder
Anomalous bodily experiences and automaton-like feelings constitute some of the core symptoms of depersonalization disorder (DP), features which may be considered antithetical to mindfulness. We thus

Based on study findings, emotion regulation skills should be promoted to help individuals with elevated depersonalization manage their emotion-oriented coping strategies, anxiety, and emotional overexcitability.
The Circumplex Structure of Depersonalization/Derealization
This paper presents a literature review to determine whether precipitating causes of depersonalization (DP) and derealization (DR) correspond to the circumplex model of emotion defined by the
Cognitive-Affective Neuroscience of Depersonalization
An evolutionary perspective suggests that attenuation of emotional responses, mediated by deactivation of limbic structures, may sometimes be advantageous in response to inescapable stress.
Italian (cross cultural) adaptation and validation of the Cambridge Depersonalization Scale (CDS)
Current epidemiological data show a prevalence of clinically significant DP (DP disorder in DSM-IV TR) in general population of approximately 1–2%, similar to prevalence found for common mental disorders, such as bipolar and obsessive-compulsive disorder.


The Cambridge Depersonalization Scale: a new instrument for the measurement of depersonalization.
The Cambridge Depersonalization Scale is meant to capture the frequency and duration of depersonalized symptoms over the 'last 6 months' and showed high internal consistency and good reliability, and can be profitably used in both clinical and neurobiological research.
The Phenomenological Stability of Depersonalization: Comparing the Old with the New
The results suggest that the phenomenology of depersonalization has remained stable over the last 100 years and it makes sense to continue collecting as many symptoms as possible, thereby avoiding both biased selection or premature closure.
Toward the clarification of the construct of depersonalization and its association with affective and cognitive dysfunctions.
Inauthenticity, the most frequent and pervasive form of depersonalization experience, was best predicted by a cognitive style featuring intense, critical examination of self and others, and was experienced somewhat infrequently by relatively few subjects.
Feelings of Unreality: A Conceptual and Phenomenological Analysis of the Language of Depersonalization
The paper offers a conceptual and phenomenological analysis of the language of depersonalization. The depersonalization syndrome or disorder has no known common pathogenesis and shows no
Depersonalisation disorder: clinical features of 204 cases
Depersonalisation disorder is a recognisable clinical entity but appears to have significant comorbidity with anxiety and depression and research into its aetiology and treatment is warranted.
Depersonalization: a conceptual history
Depersonalization has of late become subsumed under the dissociative disorders and it is recommended that the term is used to refer only to the original core-behaviour as this has shown adequate stability.

The symptoms of depersonalization are examined in the light of the phenomenological views evolved by Franz Brentano. He had come to the conclusion that our conscious experiences are primarily
The detection and measurement of depersonalization disorder.
Investigating the applicability of four dissociation scales to depersonalization disorder and establishing screening criteria for the disorder found that three of the scales were fairly strongly correlated to the DES, suggesting that they may measure similar but not identical concepts, and cutoff scores are proposed for these scales also.
Depersonalization: neurobiological perspectives
Autonomic response in depersonalization disorder.
The fact that patients with depersonalization disorder respond earlier to a startling noise suggests that they are in a heightened state of alertness and that the reduced response to unpleasant stimuli is caused by a selective inhibitory mechanism on emotional processing.
