Abstract

Background "Depersonalization" (DP) is a common symptom in the general population and psychiatric patients (Michal et al., 2011 [1]). DP is characterized by an alteration in the experience of the self, so that one feels detached from his or her own mental processes or body (or from the world), feeling as being an outside observer of his or her own self, and loosing the experience of unity and identity (American Psychiatric Association, 2013 [2]). Aim We performed an exploratory factor analysis of the Cambridge Depersonalization Scale Italian version (CDS-IV). Methods We enrolled 149 inpatients and outpatients of psychiatric services located in two Italian regions, Lazio and Campania. Patients were aged between 15 and 65 and diagnosed with schizophrenic, depressive or anxiety disorders. Results Four factors accounted for 97.4% of the variance. Factor 1 (10, 24, 26, 1, 13, 23, 9, 2, 5, and 11), called "Detachment from the Self", captures experiences of detachment from actions and thoughts. Factor 2 (19, 20, 27, 3, 12, 23, 22, and 11), called "Anomalous bodily experiences", refers to unusual bodily experiences. Factor 3 (7, 28, 25, 6, 9, and 2), named "Numbing", describes the dampening of affects. Factor 4 (14, 17, and 16), named "Temporal blunting", refers to the subjective experience of time. We did not find any specific factor that refers to derealization; this suggests that the constructs of depersonalization/derealization (DP/DR) were strongly related to each other. Conclusions Our results show that the constructs of DP/DR subsume several psychopathological dimensions; moreover, the above mentioned factors were broadly consistent with prior literature.
