The relationship between dyadic adjustment and psychiatric symptomatology in expectant couples: An actor–partner interdependency model approach

Background: Many researchers who evaluated psychological distress during the transition to parenthood agree in identifying pregnancy as the most sensitive period for the onset of psychiatric symptomatology for both parents. Furthermore, research highlights a correlation between symptoms experienced by fathers in relation to those experienced by mothers. Objective: The aim of this study was to investigate whether dyadic functioning influences the level of psychiatric symptomatology in couples expecting their first child. Participants were 137 couples expecting their first child; they were recruited at the San Filippo Neri and the Santo Spirito hospitals in Rome (ASLROMA1). We used an Actor-Partner Interdependence Model (APIM) to test the interdependence of both partners and the effect of dyadic relationships on psychiatric symptoms in the couple. Results: The overall test of distinguishability yielded a chi square value of 122.167 (23 df; p < .001). The actor-partner interdependence model showed significant paths between couple coping and psychiatric symptomatology. Specifically, we found that the quality of couple coping perceived by the mother negatively predicted maternal psychiatric symptomatology, and the quality of couple coping perceived by the father negatively predicted paternal psychiatric symptomatology. Furthermore, the quality of couple coping perceived by the father negatively predicted maternal psychiatric symptomatology. Conclusions: The results of this study confirm that dyadic adjustment is an important element for the development of effective interpersonal relationships. These data highlight the importance of promoting psycho-educational and clinical courses and programs for the development of social support with future parents.
