Perinatal posttraumatic stress disorder (P-PTSD) is not commonly included in the conversation regarding mental health concerns for perinatal or postpartum women. There is both limited research in this area as well as limited recognition of P-PTSD. Because of the lack of recognition of P-PTSD, precise prevalence rates are uncertain. The need for better awareness and understanding of P-PTSD among mental health clinicians, medical providers, and interdisciplinary care teams is imperative to best support women experiencing symptoms. The study and recognition of P-PTSD is invaluable because effects of P-PTSD for a mother and her family can be deleterious. P-PTSD affects a mother’s social network and interpersonal relationships, including potentially her relationship with her child. An empathic and well-informed clinician can help to mitigate these outcomes. This article seeks to educate clinicians about P-PTSD and discusses the prevalence, risk factors for, and clinical presentation of this disorder, including a consideration of cultural factors. The need for more effective and relational screening for these disorders, as well as treatment methods, are also discussed. Future research on P-PTSD is warranted across assessment, treatment, and cultural considerations. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
