A promising new model of care for postpartum depression: A randomised controlled trial of a brief home visitation program conducted in Houston, Texas, USA

Abstract

Postpartum depression (PPD), a perinatal mood and anxiety disorder (PMAD), is a leading cause of complications of pregnancy and childbirth. In the United States, approximately 20 percent of women suffer from PMADs. In Houston, Texas, an estimation of 12,000 - 15,000 women experience PPD each year. Within the Texas Children's Paediatrics network, a large paediatric network located in Houston, Texas, mothers are screened during paediatric well-child visits and those screening positive receive a referral to a psychiatrist with the network. However, there are not enough psychiatrists to meet the demand of services and Black, Latina, and women on Medicaid during pregnancy are less likely to attend a psychiatric visit compared to White, non-Hispanic women. This study used a randomised control trial design to measure the effectiveness of an alternative treatment option for a racially diverse population of postpartum women with mild to moderate symptoms of PPD, a five-session home visitation program using the Problem-Solving Tools for PPD (PST4PPD) model delivered by master's level social workers. The control group was allocated to standard treatment with a psychiatrist. A total of 118 women gave consent and were randomised, 72 to home visiting and 46 to psychiatry. Results demonstrated that all participating mothers had significant decreases in PPD symptoms. The change in PPD symptoms among those in the home visitation program was not significantly different from the change in the control condition, indicating that the home visitation program was as effective as psychiatric treatment in significantly reducing PPD symptoms. Additionally, a high proportion of women in the home visitation program completed visits and demonstrated increased maternal self-efficacy. Based on these results, a short-term home visitation program by a social worker (PST4PPD) appears to be a promising treatment option for postpartum women with mild to moderate PPD symptoms.
