Can a simple digital game ease traumatic flashbacks?
NCT ID NCT05849337
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a brief digital task can reduce the number of upsetting, involuntary memories that women experience after a traumatic event. About 380 women from Iceland who have at least three such memories per week will be randomly assigned to one of three groups: a memory-competing task, a psychoeducation task, or usual care. The main goal is to see if the task lowers the weekly count of intrusive memories after five weeks.
