Depression screening may not capture significant sources of prenatal stress for Black women

Exposure to stress during pregnancy, including depression, has a significant impact on maternal health. Black women experience varied stressors that impact pregnancy outcomes. Although the move to engage in universal screening of women for depression is a positive step toward improving women's health, it has been deployed without a comprehensive examination of its utility for capturing exposure to other stressors with known associations with perinatal and neonatal health problems for Black women such as discrimination stress. In the present study, we examine the overlap between several sources of stress and a positive screen on the Edinburgh Postnatal Depression Scale (EPDS) in Black pregnant women. Data were gathered from a study examining the effects of stress on prenatal health (N = 168). Discrimination stress, structural and systemic racism stress, perceived stress, and partner abuse were measured using standardized questionnaires during pregnancy. Using a score of ≥ 13 to indicate probable depression the sensitivity of the EPDS to identify women who experienced high levels of discrimination stress (41.7%), structural and systemic racism (39.5%), perceived stress (63.4%), and partner abuse (45.2%) was suboptimal. Lowering the threshold for a positive screen on the EPDS to a score of 10 improved sensitivity but did not solve the problem of under-identification of women whose health is at risk. The focus on depression screening for pregnant women should be re-considered. A screening toolkit that more rigorously and broadly assesses risk and need for support and intervention is needed to improve perinatal health outcomes for Black women.
