Postpartum Depression & Child Development | Long-Term Effects
- A new study highlights the significant connection between postpartum depression,early mother-to-infant bonding,and a child's emotional and behavioral development.
- The study, lead by Associate Professor Daimei Sasayama of Shinshu University School of Medicine, examined 245 mother-child pairs in Okaya, Japan.
- The team used the Edinburgh Postnatal depression Scale (EPDS) and the Mother-to-Infant Bonding Scale-Japanese version (MIBS-J) to evaluate maternal depressive symptoms and bonding.
Understand the critical link between postpartum depression and child progress. This breaking study, published June 18, 2025, reveals how early mother-infant bonding may counteract the long-term impacts of maternal depression. Scientists discovered a direct correlation, highlighting the need for interventions that strengthen the mother-child relationship. Data from Japan shows the effects, and particularly how boys experienced a greater impact.

Postpartum Depression,Mother-Infant Bonding Linked to Child Growth
A new study highlights the significant connection between postpartum depression,early mother-to-infant bonding,and a child’s emotional and behavioral development. Researchers in Japan found that secure early bonding experiences could potentially buffer the long-term effects of maternal depression on child outcomes.
The study, lead by Associate Professor Daimei Sasayama of Shinshu University School of Medicine, examined 245 mother-child pairs in Okaya, Japan. The children were born between April 2, 2009, and April 1, 2012. The research,published in Archives of Women’s Mental Health on April 15,2025,used scales to assess maternal depressive symptoms,mother-infant bonding,and child difficulties.
The team used the Edinburgh Postnatal depression Scale (EPDS) and the Mother-to-Infant Bonding Scale-Japanese version (MIBS-J) to evaluate maternal depressive symptoms and bonding. Child difficulties were measured using the Japanese version of the Strengths and Difficulties Questionnaire (SDQ). Data was collected from mothers about two weeks to one month postpartum, and from sixth-grade children and their caregivers.
The findings indicated that 17.1% of mothers experienced postpartum depressive symptoms, aligning with national rates in Japan. These symptoms showed direct and indirect links to mother-infant bonding and child difficulties. The study suggests that early interventions targeting bonding could promote healthier child outcomes by addressing maternal mental health and improving mother-infant relationships.
“Interestingly, it was found that mother-to-infant bonding mediated 34.6% of the effects of postpartum maternal depression on child difficulties, which confirmed the study’s hypothesis,” said dr. Sasayama.
The research also revealed that boys in the study showed higher total difficulty scores than girls, particularly in conduct and hyperactivity or inattention. However, both child and caregiver reports indicated greater difficulties among children whose mothers had postpartum depressive symptoms. The study emphasizes the lasting impact of early bonding experiences on a child’s psychosocial growth.
What’s next
Future research should investigate which specific depressive symptoms most significantly affect bonding, using larger sample sizes. These studies should also consider genetic data, socioeconomic factors, and other underlying mechanisms to design targeted interventions for mothers and their families.
