Peritraumatic versus persistent dissociation in acute stress disorder
Abstract
The DSM-IV definition of acute stress disorder (ASD) regards dissociation that occurs during a trauma (peritraumatic dissociation) comparably to persistent dissociation. This study investigated the relative contributions of peritraumatic dissociation and persistent dissociation to acute posttraumatic stress reactions. Civilian trauma (N = 53) survivors with either acute stress disorder (ASD), subclinical ASD, or no ASD were administered modified versions of the Peritraumatic Dissociative Experiences Questionnaire that indexed both dissociation during the trauma and dissociation at the time of assessment. Persistent dissociation was more strongly associated with ASD severity and intrusive symptoms than peritraumatic dissociation. These results are consistent with the proposition that persistent, rather than peritraumatic, dissociation is associated with posttraumatic psychopathology.

“By hindering processing, persistent dissociation, similar to other types of cognitive and behavioral avoidance (Foa & Hearst-Ikeda, 1996; Panasetis & Bryant, 2003; Wagner & Linehan, 1998) may contribute to both memory fragmentation and PTSD development.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
