Preventing Childbirth-Related PTSD With Expressive Writing

The goal of this clinical trial is to test a brief psychological intervention given to individuals in the first days following childbirth who have experienced a potentially stressful childbirth. The treatment is aimed at preventing post-traumatic stress disorder following childbirth and promoting maternal-infant bonding. In the days following childbirth, participants will be asked to write about their childbirth experience or a neutral event for three consecutive days, for around 15 minutes each day. Additionally, they will complete a short survey before and after the intervention about their birth experience and mental health. Around 2 months postpartum (with the option of up to around Month 3 PP), participants will take part in mental health and physiological assessments, and in a brief play session with their infant.
