Relationships between parent-infant bonding, dyadic adjustment and quality of life, in an intra-partner sample.

The transition to parenthood represents a moment of change and adaptation in which the dyadic marital relationship becomes a triadic relationship. Facilitating a positive transition requires a thorough understanding of the explanatory model of the relationship between parental-infant bonding, dyadic adjustment and quality of life (QoL) from an integrative perspective of the family unit. The aim of this work was to analyse the relationships between parent-infant bonding, dyadic adjustment and QoL from an intra-partner perspective, 6-12 months after the birth of a child. A cross-sectional observational study was performed in a convenience sample of 222 couples 6-12 months postpartum, enrolled from October 2013 to March 2016. The mean age of the mothers was 34.07 years (SD = 3.67), and for the fathers, it was 35.75 years (SD = 4.02). Mothers perceived better QoL and greater mother-infant bonding compared to fathers. The perception of an adequate dyadic adjustment, together with positive parent-infant bonding, had positively influenced the individual QoL of both members of the couple 6-12 months after birth. From an intra-partner perspective, the positive transition was influenced by the relationship between parent-infant bonding, dyadic adjustment and QoL. Positive parent-infant bonding in mothers and fathers, as well as promotion of the quality of the relationships between couples, can help promote a better QoL. Positive health results can be achieved in terms of individual and family well-being by designing healthcare interventions that encourage the presence and participation of the family unit.
