Temporal Disintegration in Depersonalization Disorder

ABSTRACT Distortions of the experience of time are central to some types of dissociative experiences. In this study, we investigated the relationship between a self-report measure of temporal disintegration and symptoms of dissociation in depersonalization disorder (DPD). Fifty-two DPD and thirty non-clinical control participants were administered the Dissociative Experience Scale (DES) and Temporal Integration Inventory (TII). The DPD group had significantly higher TII scores than the control group. Within the DPD group, there was a significant positive correlation between DES total score and TII total score, and between TII-time distinction subscale score and TII-agency subscale score. In the DPD group, TII scores were not associated with age of onset or duration of illness. Of the three dissociative domains of absorption, amnesia, and depersonalization/derealization, only absorption was a significant predictor of TII total and subscale scores by stepwise linear regression analyses. We conclude that the experience of temporal disintegration in DPD is not directly related to the core symptoms of depersonalization/derealization, but exists when the depersonalized experience involves more prominent absorption.
