Attachment and coparenting representations in men during the transition to parenthood.

Coparenting is based on parents' representations of themselves as coparents. Attachment theory can be a useful framework to understand the way that different coparenting representations are developed during the transition to parenthood. This study aimed to analyze the association between men's attachment and coparenting representations at the first trimester of pregnancy and from the first trimester of pregnancy to 6 months' postpartum. A sample of 86 men was recruited and completed self-report measures of attachment and coparenting representations at the first and third trimester of pregnancy and at 1 and 6 months' postpartum. At the first trimester of pregnancy, higher attachment avoidance was associated with higher lack of coparenting support. From the first trimester of pregnancy to 6 months' postpartum, higher attachment avoidance was associated with (a) a steeper increase on lack of coparenting support, (b) an increase on coparenting conflict (while low attachment avoidance was associated with a decrease), and (c) a lower decrease on coparenting disagreement. This study may contribute to coparenting research by showing new evidence on attachment theory as a useful framework to understand how different coparenting representations are developed in men during the transition to parenthood.
