  • Title: Peritraumatic dissociation after loss: latent structure and associations with psychopathology.
    Author: Boelen PA, Keijsers L, van den Hout MA.
    Journal: J Nerv Ment Dis; 2012 Apr; 200(4):362-4. PubMed ID: 22456592.
    Abstract:
    This study investigated the factor-structure of retrospectively assessed peritraumatic dissociation in the moments surrounding the death of a loved one and concurrent and prospective associations of such peritraumatic dissociation with loss-related emotional distress. Data were available from 168 people, bereaved in the preceding year. They completed the Peritraumatic Dissociative Experiences Questionnaire with their loss as the index event, together with measures of prolonged grief disorder, depression, and posttraumatic stress disorder; 117 completed symptom measures again 1 year later. Confirmatory factor analysis comparing the fit of four competing models showed that the eight-item one-factor model found in the first study using the Peritraumatic Dissociative Experiences Questionnaire provided the best fit to the data. Peritraumatic dissociation predicted concurrent and prospective symptom levels even when controlling for neuroticism and demographic and loss-related variables.
