Sponsor's own description

This research study is designed to investigate the use of a simple cognitive task (a memory cue followed by playing the computer game "Tetris") for decreasing the number of intrusive memories of trauma among trauma-exposed women in Iceland. This is a single case series using a within subject multiple baseline AB design. Participants will aim to complete a no-intervention phase ('A': baseline phase) of one week followed by a one-week intervention phase ('B'), including a one-session intervention with a researcher comprising the simple cognitive task, followed by instructions to continue using the technique self-guided in subsequent weeks. Participants will be asked to monitor the occurrence of intrusive memories of trauma in a daily diary. It is predicted that participants will report fewer intrusive memories during the intervention phase than during the preceding baseline phase and that the frequency of targeted intrusive memories is going to decrease relative to non-targeted intrusive memories. Furthermore, we will explore whether having fewer intrusive memories has an impact on function and/or PTSD, depressive or anxiety symptoms.
