Abstract

People of color in the United States disproportionately bear the burden of trauma and posttraumatic stress disorder (PTSD). Pregnant women of color are at particular risk, as perinatal PTSD is associated with adverse maternal and child health. However, PTSD is a heterogeneous disorder comprising discrete symptom dimensions. Adopting a dimensional understanding of PTSD could aid in identifying women at-risk for the consequences of posttraumatic psychopathology and guide treatment selection. In a large sample of Latina, Black, and non-Hispanic White postpartum women in the United States (N = 1663), we examined racial and ethnic differences in the factors of the dysphoric arousal model—a leading dimensional model of PTSD. This model is characterized by five symptom dimensions: re-experiencing, avoidance, numbing, dysphoric arousal, and anxious arousal. Past-year trauma in this sample was common, afflicting nearly 70% of women. In unadjusted models, women of color exhibited more severe PTSD symptom levels across dimensions except for dysphoric arousal, with Black mothers particularly affected. In models adjusted for age, education, and poverty, Black women continued to report elevated symptoms of avoidance and, relative to Latina mothers, re-experiencing symptoms. In contrast, White women reported more dysphoric arousal symptoms relative to women of color. Illuminating differential patterns of symptom dimensions across racial and ethnic groups is critical to PTSD assessment and treatment and may shed light on disparities. Perinatal healthcare may be an important opportunity for posttraumatic symptom screening, and greater understanding of racial and ethnic variation in posttraumatic symptom dimensions can guide targeted intervention selection for perinatal women.
