A Quasi-Experimental Study: Social Support in Group Prenatal Care’s Impact on Postpartum Depression in Black and Hispanic Women

Depression is a widespread mental health condition that affects millions of women globally. In the United States (U.S.), more than half of maternal mental health-related deaths occur during the postpartum period, making it the leading cause of mortality during this time. This urban U.S. single-site quasi-experimental study aimed to evaluate the effectiveness of social support integrated into group prenatal care as an intervention for postpartum depression. The study employed a dual methodological approach, combining prospective participant recruitment with a retrospective analysis of medical records. It compared the Edinburgh Postnatal Depression Scale (EPDS) scores from group prenatal care to those from traditional individualized prenatal care, specifically focusing on Black and Hispanic women. In all, 200 postpartum women participated in the study, comprising (n = 100) group prenatal care and (n = 100) traditional individualized care. Most participants were Black (97%), with an average age of 26.8 years (SD = 5.9). At six weeks postpartum, 97% of the participants underwent depression screening, which indicated a mean EPDS score of 3.79 (SD = 4.7). Among the participants, 25% exhibited mild to moderate postpartum depression, while 3% experienced severe depression. No significant differences were observed between the models of care in terms of total scores (T = 2.0, p = 0.46) or score ranges (χ 2 = 5.8, p = 0.12). It is noteworthy that no severe cases of depression were identified within the group prenatal care model. Suggesting group prenatal care may still benefit Black and Hispanic women in urban areas with a history of anxiety or depression.
