The Interplay Between Maternal and Paternal Senses of Efficacy Moderates the Link Between Perinatal Parental Stress and Family Alliance at 3 Months

Objective. Both parents may report high levels of stress during the perinatal period with possible negative consequences for parental well-being and child development. Parental sense of efficacy moderates the effect of stress. To date, no studies have assessed links between parental stress and mother-father-infant interactions in terms of family alliance and the extent to which each parent’s sense of efficacy moderates these links. Design. In this study, 65 dual-parent families answered a questionnaire about parental stress between 36 and 38 weeks of pregnancy and at 3 months after birth. Families were also observed while playing with their 3-month-old infant in the Lausanne Trilogue Play, and they completed a questionnaire about parental efficacy. Results. Structural equation modeling analyses showed that higher maternal or paternal postnatal stress has a direct link with higher family alliance and the links between stress and family alliance are moderated by complex interaction effects between maternal and paternal senses of efficacy. Conclusions. This study shows the necessity of considering the interaction between the senses of self-efficacy of both parents as moderators of parenting stress.
