  • Title is in Icelandic Reducing the Frequency of Intrusive Memories After Trauma Using a Visuospatial Intervention: A Pilot Study
  • Master's
  • Objectives: Intrusive memories are the core clinical symptom of posttraumatic stress disorder (PTSD). There is an urgent need for scalable and accessible interventions for intrusive memories that do not require much therapist involvement. The current study tested a novel intervention, the visuospatial task Tetris, to reduce the frequency of intrusive memories. Method: The participant (N = 1) is a 52 year old woman who had four different intrusive memories from a childhood trauma. A within-subject multiple baseline AB design was used, with a baseline (“A”; monitoring only, 4 weeks) and intervention (“B”; 6 weeks) phases, and a 1-month follow-up. The participant monitored the occurrence of intrusive memories in a diary for all phases. All intrusions were targeted at different times by the intervention (including a memory reminder for a specific intrusive memory followed byTetris gameplay with mental rotation for 25 minutes) that she received on a weekly basis during the intervention phase. Results: The total frequency of intrusive memories reduced on average 59% from baseline to postintervention and was reduced further to 72% at 1-month follow-up. Symptoms of PTSD and depression were reduced in a clinically significant way postintervention and at the 1-month follow-up. The participant considered the intervention to be acceptable and highly effective. Discussion: The results indicate that the intervention can be effective in reducing the frequency of intrusive memories and is a feasible and acceptable way to target intrusive memories after trauma. Tetris gameplay is an accessible and scalable intervention which may improve mental health of trauma survivors.
