Prematurity, maternal posttraumatic stress and consequences on the mother–infant relationship

Abstract

Objective Premature birth is a stressful experience for parents. This study explores the links between maternal posttraumatic stress, maternal attachment representations of the infant and mother–infant dyadic interactions. Methods The study enrols 47 preterm (GA < 34 weeks) and 25 full-term infants. The Perinatal Posttraumatic Stress Disorder Questionnaire was administered to evaluate maternal posttraumatic stress symptoms. At 6 months of corrected age, maternal attachment representations of the infant were explored and coded with the Working Model of the Child Interview. Interactive characteristics were explored in a videotaped play session and coded with the Care Index. Results Full-term mothers were more likely to follow a “Cooperative” dyadic pattern of interaction with the infant and demonstrate Balanced representations of the infant. Preterm mothers with high posttraumatic stress symptoms were more likely to follow a “Controlling” dyadic pattern of interaction, with more Distorted representations. In contrast, preterm mothers with low posttraumatic stress symptoms were more likely to fall into a “Heterogeneous” group of patterns of dyadic interaction, with Disengaged representations. Interestingly, in Cooperative preterm dyads, only 23% of the mothers demonstrated Balanced representations, despite rates of 69% in full-term Cooperative dyads. Conclusion Premature birth affects both mother–infant interaction characteristics and maternal representations of attachment with the infant. In particular, a “Controlling” dyadic pattern was associated with high maternal posttraumatic stress symptoms and Distorted maternal representations. It is important to examine the impact of maternal posttraumatic stress on the parent–infant relationship in order to plan supportive, preventive interventions in the neonatal period.
