Tetris-backed intervention after memory reactivation to help with intrusive memories

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized trial, participants with PTSD who experience at least three intrusive memories per week are assigned to either a memory-reactivation plus Tetris task or a control condition with only the visuospatial task. The intervention begins with trauma-related memory reactivation, followed by a music interval and a visuospatial interference task using Tetris; the control arm performs only the visuospatial task. Intrusive memories and related symptoms are tracked during follow-up to see if the combined approach offers added benefit. Participants provide trauma-related images for the reactivation procedure, and study procedures are conducted online with computer access. The trial is conducted at Shaanxi Normal University in Xi'an, China, led by the School of Psychology.
