Post-Traumatic Stress and Autobiographical Memory Accuracy in Young Children: Traumatic Events Versus Stressful and Pleasant Events.

This study examined the influence of trauma exposure and posttraumatic stress (PTS) severity on accuracy of recall of autobiographical memory of traumatic events and pleasant events in very young children. Two hundred sixteen 3-6 year-old children with trauma exposure were interviewed with standardized interviews. Forty-one non-trauma-exposed controls were interviewed about stressful events for comparison. Accuracy of recall for both traumatic and pleasant events was not associated with severity of PTS. Trauma-exposed children showed significantly less accurate recall of trauma events compared to pleasant events. This difference was limited to children who experienced repeated trauma or Hurricane Katrina-related trauma experiences as opposed to single-blow types of trauma experiences. There was no difference in accuracy of recall of trauma events in the trauma-exposed group versus stressful events in the control group. There was also no difference in accuracy of recall of pleasant events between the trauma-exposed and the control groups. These findings do not support traditional theories that autobiographical recall is impaired in those with posttraumatic stress disorder or with trauma exposure. These findings demonstrate that very young children have access to and can verbalize accurate autobiographical recall of trauma events, which is important for clinical assessment and treatment.
