Clinical Trial Summary

This proof-of-principle study aims to investigate the effects of a brief behavioural procedure including a computerized visuospatial task (the computer game "Tetris") preceded by a reactivation of the traumatic memory of childbirth, on birth-related intrusive traumatic memories and other postpartum posttraumatic stress symptoms. Women who report birth-related intrusive memories after 6 weeks postpartum will monitor their intrusive traumatic memories in a daily diary. After two weeks of diary, they will meet a psychologist to briefly evoke the memory of their birth, and receive a brief behavioural procedure including playing Tetris. Participants will then continue to complete an intrusive traumatic memory diary during two weeks. It is predicted that they will report fewer intrusive memories in the two weeks following the intervention, compared to the two weeks before. This will inform the potential future development of a simple computerized intervention procedure to reduce distressing psychological symptoms after traumatic childbirth.

Other	Intervention acceptability	10-point Likert scale (1= The intervention was not at all acceptable; 10 = The intervention was extremely acceptable).	1 month after the intervention
Primary	Frequency of intrusive memories of the index trauma	Frequency of intrusive traumatic memories related to childbirth recorded by participants in a trauma-related intrusive memories diary over the two weeks after the intervention	Within 2 weeks following the intervention
Secondary	Presence and severity of maternal PTSD symptoms	PTSD Checklist (PCL-5) for DSM-5	1 month after the intervention
Secondary	Frequency of intrusive memories of the index trauma	Frequency of intrusive traumatic memories related to childbirth recorded by participants in a trauma-related intrusive memories diary between the 4th and 6th weeks following the intervention	Between 4 and 6 weeks after the intervention
Secondary	Psychological distress related to intrusive memories of the index trauma	Rating scale for psychological distress related to intrusive memories related to childbirth that are reported in an intrusive memories diary over the two weeks after the intervention.
