Prenatal emotional training cuts postpartum depression risk for multiparous women

Postpartum depression strikes roughly one in seven women after they give birth, and the consequences can be severe—maternal suffering, fractured family life, and in the darkest cases, suicide or harm to the infant. It is not the temporary emotional turbulence of the baby blues, which fade on their own in the first days. This is a serious mood disorder that lingers and deepens. Researchers have long searched for ways to prevent it, and a new trial presented at the ECNP Congress in Munich suggests an unexpected answer: a five-week prenatal training program that teaches expectant mothers to read and respond to their baby's emotional signals—but the benefit appears to work primarily for women who have given birth before.

The study enrolled 147 pregnant women from the Copenhagen area who were identified as at heightened risk for postpartum depression. Half received prenatal affective cognitive training, or PACT, delivered through computerized sessions and virtual reality exercises over five weeks. The other half received standard prenatal care. The training itself was straightforward in concept: expectant mothers learned to notice emotional cues from infants, practiced interpreting what those cues meant, and rehearsed different ways of responding to difficult situations they might encounter once the baby arrived. The goal was to build competence and confidence before the actual challenges emerged.

When researchers followed up with 121 of the original participants, the results split along an unexpected line. Across all women in the study, those who received training showed better outcomes than those who did not, but the difference was not statistically significant. However, when the researchers looked only at women who had previously given birth, the picture changed sharply. Among multiparous women who completed the training, just 5.3 percent developed postpartum depression. In the control group of women with prior births who received no training, 34.6 percent developed the condition. That is a dramatic gap—a reduction of nearly 85 percent.

Anne Juul Bjertrup, the study's lead author from the NEAD Centre in Copenhagen, acknowledged that this finding surprised the research team. "The strongest finding was among women who had previously given birth, which was something we didn't expect," she said. One plausible explanation emerged from how the training itself was structured. Participants were asked to imagine their future infant and to practice emotional and cognitive exercises around those imagined interactions. Women who had already experienced pregnancy and birth possessed a concrete mental reference point for these tasks—they could draw on actual memories of what a newborn feels like, how they cry, what their needs look like. First-time mothers, by contrast, were working from abstraction and anticipation.

The findings point toward a broader insight: postpartum depression may not arise solely from how a woman feels during pregnancy, but from how she processes emotional information and responds to her baby's signals. If that is true, then pregnancy itself becomes a window of opportunity—a time when the brain is primed for change and when intervention might take root before the baby arrives and the acute demands begin. Bjertrup emphasized that the results remain preliminary. Postpartum depression has no single cause; it emerges from a tangle of biological and psychosocial factors. Larger trials are needed to confirm that the benefit truly depends on parity, to identify which components of the training actually matter, and to determine which women are most likely to benefit from it.

Dr. Benedetta Vai, a psychiatrist at Università Vita-Salute San Raffaele in Italy and a member of the ECNP's perinatal psychiatry network, offered cautious enthusiasm. She noted that the training appeared to help women interpret their baby's cues in a more positive light, which could create what she called a "virtuous circle"—easier mutual regulation between mother and infant from the start. For women with prior children, this matters especially. Some carry difficult memories from a first pregnancy or birth. Managing a newborn while also caring for a toddler is exhausting and complex. A tool that helps a mother attune more skillfully to her infant's needs could ease that burden significantly. Still, Vai stressed, the finding needs confirmation in larger studies, ideally ones that also measure the quality of the mother-infant relationship itself. The direction is promising, but the evidence remains incomplete.
