Postnatal Depression (PND) continues to have lifelong detrimental effects on mother-child relationships, which can also affect multi-generational relationships.
PND is well-known to have an adverse effect on mothers' relationships with their children. This has a subsequent impact on child development from early infancy to adolescence and influences emotional, cognitive, and physical development in children.
Now, the research was led by Dr Sarah Myers and overseen by Dr Sarah Johns in the School of Anthropology and Conservation.
Their data showed that women who had PND reported lower relationship quality with their offspring, including those children who are now adults and that the worse the PND had been the worse the later relationship quality was.
While mothers who experienced depressive symptoms at other times had worse relationships with all of their children, PND was found to be specifically detrimental to the relationship mothers had with their child whose birth triggered the PND.
This suggests that factors which affect mother-child relationships in early infancy can have lifelong consequences on the relationship that is formed over time.
Another discovery from the research was that women who suffer from PND with a child, and then in later life become a grandmother via that child, form a less emotionally close relationship with that grandchild. This continues the negative cycle associated with PND as the importance of grandmothers in helping with the rearing of grandchildren is well-documented.
The researchers hope the findings will encourage the ongoing development and implantation of preventative measures to combat PND. Investment in prevention will not only improve mother-child relationships, but also future grandmother-grandchild relationships.
The paper, titled Postnatal depression is associated with detrimental life-long and multi-generational impacts on relationship quality, has been published in the open-access journal PeerJ.
