•We experimentally manipulated the temporal disorganization of traumatic memories.•We found a high rate of memory distortion that did not differ across conditions.•Self-reported disorganization was associated with more memory distortion.•Self-reported disorganization was associated with more analogue PTSD symptoms.
Background and ObjectivesEmpirical studies with objective measures and control conditions have failed to demonstrate disorganization; yet people tend to self-report disorganization in their trauma narratives, which may have other effects. Thus, we investigated whether a disorganized trauma memory produces more analogue PTSD symptoms and memory distortion, compared to an organized memory.MethodsParticipants watched a traumatic film with missing scenes. Some saw the scenes in their correct temporal sequence; others saw a random sequence; thus for some participants we implanted a disorganized memory. We also told some participants to focus on the meaning of the event (conceptual), some on the sensory details (data-driven), and some received no instruction (control). Participants recorded their intrusions for a week. Then, they reported analogue symptoms and we tested their memory for the film and their confidence in what they remembered.ResultsAnalogue symptoms and number of reported intrusions did not differ across conditions, nor did the degree of memory distortion or confidence in those memories. However, participants who self-reported feeling more memory disorganization reported more avoidance symptoms and more memory distortion.LimitationsWe did not measure memory for real trauma, nor did we assess for a history of PTSD. Our results may also be restricted to temporal disorganization.ConclusionsAlthough objective assessments of disorganization do not appear important, people's feelings regarding the disorganization of their memories not only affect their assessment of the severity of their PTSD symptoms, but also the kinds of memory errors they make.
