Temporal disintegration is common in depersonalization disorder (DPD). This study found temporal disintegration relates to absorption, not core depersonalization symptoms, in DPD patients.

Area of Science:

  • Psychology
  • Neuroscience
  • Psychiatry

Background:

  • Distortions in time perception are characteristic of dissociative experiences.
  • Depersonalization disorder (DPD) involves persistent feelings of detachment from oneself and one's surroundings.

Purpose of the Study:

  • To examine the relationship between temporal disintegration and dissociative symptoms in individuals with DPD.
  • To identify which specific dissociative domains predict temporal disintegration in DPD.

Main Methods:

  • Fifty-two individuals diagnosed with DPD and thirty non-clinical controls completed the Dissociative Experience Scale (DES) and Temporal Integration Inventory (TII).
  • Statistical analyses, including correlation and stepwise linear regression, were employed to assess relationships between variables.

Main Results:

  • The DPD group exhibited significantly higher Temporal Integration Inventory (TII) scores compared to the control group.
  • Within the DPD group, higher TII scores positively correlated with Dissociative Experience Scale (DES) scores.
  • Absorption, a dissociative domain, significantly predicted TII scores, while amnesia and depersonalization/derealization did not.

Conclusions:

  • Temporal disintegration in DPD is associated with the dissociative domain of absorption.
  • The findings suggest that temporal distortions in DPD are linked to the extent of absorption rather than core depersonalization/derealization symptoms.
