Postpartum-onset PTSD: a DSM-6 nosologic priority.

Childbirth-related PTSD is a population-level postpartum mental health concern that remains under-recognized due to limited routine PTSD screening and symptom overlap with postpartum depression and anxiety. The condition is associated with impaired mother-infant bonding and is supported by converging biological evidence consistent with PTSD in other trauma-exposed populations. We propose that DSM-6 add a PTSD timing specifier, "with postpartum onset", defined as the onset of PTSD symptoms within 4 weeks after delivery following a childbirth event that satisfies DSM Criterion A. A full PTSD diagnosis would still require that symptoms persist for more than 1 month, as required by DSM criteria. This targeted update could improve recognition, coding, screening pathways, and research harmonization for childbirth-related PTSD.
