“…(2 By contrast, higher dynamical and embodied engagements with the surroundings should lead to lower depersonalization. Our findings seem to provide a significant support for (1) and a weak significant support for (2). Indeed, we found a weak significant negative correlation between the frequency of physical exercise during the lockdown and the occurrence of depersonalisation experiences.…”

Depersonalisation is a common dissociative experience characterised by distressing feelings of being detached or ‘estranged’ from one’s self and body and/or the world. The COVID-19 pandemic forced millions of people to socially distance from others and to change life habits. We have conducted an online study on 622 participants worldwide to investigate the relationship between digital media-based activities and distal social interactions in influencing peoples’ sense of self during the lockdown as opposed to before the pandemic. We found that increased use of digital media-based activities and online social e-meetings correlated with higher feelings of depersonalisation. We also found that people reporting higher experiences of depersonalisation also reported enhanced vividness of negative emotions (as opposed to positive emotions). Our study also reveals a weak negative correlation between the frequency of physical exercise during the lockdown and the occurrence of depersonalisation experiences. Finally, participants who reported that lockdown influenced their life to greater extent had higher occurrences of depersonalisation experiences. Our findings may help address key questions regarding well-being during a lockdown, in the general population. Our study points to potential risks related to an overly sedentary and hyper-digitalized life habits that may induce feelings of living in one’s ‘head’ (mind), disconnected from one’s body, self and the world.

“…Responses are made on a scale from 0 ( Never ) to 4 ( All the time ) with higher scores representing a greater frequency of depersonalization experiences. Factor analyses of the CDS have demonstrated that the scale is multidimensional with studies reporting on two (Blevins, Witte, & Weathers, 2013 ), four (Apontze-Soto, Vélez-Pastrana, Martínez-Taboas, & González, 2014 ; Sierra, Baker, Medford, & David, 2005 ), and five factors (Simeon, Smith, Knutelska, & Smith, 2008 ). Due to the replication and conciseness of the original four factor solution, the current study reports subscale scores for Anomalous Body Experience (nine items; e.g., “Seeing oneself outside, as if looking in a mirror”; α =0.94), Emotional Numbing (six items; e.g., “No emotions felt when weeping or laughing”; α =0.87), Alienation from Surroundings (four items; e.g., “Surroundings feel detached or unreal”; α =0.86), and Anomalous Subjective Recall (five items; e.g., “Personal memories feel as though one has not been involved in them”; α =0.85).…”

ObjectiveA dissociative subtype has been recognized based on the presence of experiences of depersonalization and derealization in relation to DSM-IV posttraumatic stress disorder (PTSD). However, the dissociative subtype has not been assessed in a community sample in relation to the revised DSM-5 PTSD criteria. Moreover, the 20-item PTSD Checklist for DSM-5 (PCL-5) currently does not assess depersonalization and derealization.MethodWe therefore evaluated two items for assessing depersonalization and derealization in 557 participants recruited online who endorsed PTSD symptoms of at least moderate severity on the PCL-5.ResultsA five-class solution identified two PTSD classes who endorsed dissociative experiences associated with either 1) severe or 2) moderate PTSD symptom severity (D-PTSD classes). Those in the severe dissociative class were particularly likely to endorse histories of childhood physical and sexual abuse. A principal axis factor analysis of the symptom list identified six latent variables: 1) Reexperiencing, 2) Emotional Numbing/Anhedonia, 3) Dissociation, 4) Negative Alterations in Cognition & Mood, 5) Avoidance, and 6) Hyperarousal.ConclusionsThe present results further support the presence of a dissociative subtype within the DSM-5 criteria for PTSD.

“…Although our study did not directly investigate this issue, our sample exhibited much higher DP scores compared to what has typically been observed in samples obtained before the COVID-19 lockdown. For example, Aponte-Soto et al 76 published a study with 300 Italian participants where they reported an average general score in CDS-29 of M = 16.3 ( SD = 18.3, range = 0–132). They also reported that only 2% (6 participants) obtained a score of ≥ 70 indicating, according to them, clinically significant DP symptoms.…”
