A systematic review of community-based interventions to address perinatal mental health.

Little is known about the scope and effectiveness of community-based interventions to address maternal perinatal mental health in the US. We searched PubMed, CINAHL, and PsychINFO in January 2024 to conduct a systematic review of studies using community-based interventions for maternal mental health from pregnancy to 1 year postpartum in the US. We reviewed 22 quantitative studies, and assessed methodological quality and effectiveness of interventions. Most were randomized trials (n = 16) with strong or good methodological quality. The majority of the studies included racially and ethnically diverse participants (n = 14), delivered interventions through community health workers, nurses, midwives, and doulas (n = 18), and had mixed effectiveness of interventions (n = 14). Limitations included small sample sizes, interventions not specifically developed for mental health, limited community involvement in designing interventions, and focus on participants with no mental health issues. Community partners augment this review with lived experience and recommendations for research and clinical practice.
