Popis: Background The hours immediately following a traumatic event may present a window of opportunity to interrupt the consolidation of memories of the traumatic event, and this may prevent PTSD development. This theory has been validated in a series of analogue studies, showing that a visuo-spatial task reduces intrusive memories, however clinical studies are scarce. Objective This pilot RCT examined the use of a semi-immersive Virtual Reality visuospatial task, as an intervention to interrupt memory consolidation, in the Emergency Department (ED) in the immediate hours following a traumatic event. We hypothesised that participants who had received the intervention would present with lower levels of PTSD symptoms than the control group who received no intervention. Method Seventy-seven adult survivors of traumatic events, meeting study criteria, were recruited in the ED of a Level III Trauma Centre. Survivors arrived at the ED less than one hour, on average, after the trauma. After signing informed consent, participants were randomized to the SnowWorld intervention or control group. Both groups completed self-report questionnaires, and the intervention group used SnowWorld for up to 10 minutes. Results No significant differences between the intervention and control groups were found regarding PTSD symptom levels two weeks and six months following the traumatic event. Conclusions These results add to the growing literature examining the use of a concurrent task to reduce intrusions following a traumatic event. In contrast to previous clinical studies, this study did not show significant group differences; however, it replicates an analogue study that used a specifically developed app. Further studies are needed to elucidate possible reasons for these conflicting results.
