Posttraumatic stress disorder (PTSD) has a worldwide lifetime prevalence of 3.9% [To develop such interventions, a relevant strategy is to specifically target the development of childbirth-related intrusive memories (IMs) [Although the involved mechanisms are still debated, evidence suggests that a brief behavioural intervention procedure including a trauma reminder cue, mental rotation, and a visuospatial task, can successfully prevent IM development [Based on laboratory results [In parallel, the intervention was tested by Horsch et al. [Despite their encouraging results, the above-mentioned studies have various major limitations. Participants and researchers were not blinded in any of these three RCTs, and the trials were powered to detect the effects of the intervention on the IMs but not on other PTSD symptoms [The aim of the present RCT was to test the efficacy of a single-session behavioural intervention including a visuospatial task procedure on the secondary prevention [
