Metacognitive appraisal of memory inconsistency for traumatic events in Dutch veterans

Abstract

Although memories of traumatic events are often remembered vividly, these memories are subject to change over time. In our previous study, we found that Dutch infantry veterans who had served in Iraq often reported stressful events at a second assessment point that they had not reported during a prior assessment point and vice versa. In the present exploratory study, we recontacted subjects from this previous study and asked how they explained the discrepancy in their memory reports between post-deployment assessment points 1 and 2. Common explanations were: interpreting the item differently, having forgotten the incident initially, repression and having accidentally incorporated someone else's experience into their own memory. Although such reports are not necessarily revelatory of the mechanisms driving discrepancies in memory reports over time, our study illuminates the metacognitive variables involved.
