Mental Health during Family Formation

During the family formation phase, the sequence of events of pregnancy, childbirth, and childcare, emotional support is important. During pregnancy, obstetricians, midwives, and nurses are the professionals who provide this support. Then, from around the one-month postpartum checkup, they shift to community health nurses and pediatricians who examine the child.
Mutual communication and cooperation among these professionals is essential, and it is increasingly desirable to improve the quality of perinatal mental health care through a multidisciplinary network. To this end, we are conducting research on advanced approaches.
While childcare support after birth is of course important, we expect that support from the pregnancy period onward will be more effective in preventing abuse. We believe that it will become increasingly important to provide care not only to mothers but also to their families, including fathers.

About Attachment Style Interview (ASI)

Attachment is a system of instinctive behaviors that humans are born with, an instinct to approach someone and seek a safe and secure relationship when faced with a crisis that could shake their emotional security. Attachment is key to the ability to form relationships with children, adults, and the elderly. In clinical practice and in research, it is important to know a person’s Degree of Security and attachment style. The Attachment Style Interview (ASI), developed by Professor Bifulco in the UK, is a method for assessing attachment security and style.
