Abstract
Understanding how attachment styles between partners relate to the dysregulation of emotions during couple conflict has received little attention, especially over the transition to parenthood. This research investigated how combinations of expectant couples' attachment styles jointly predict emotional flooding, which is a form of interpersonal emotion dysregulation. Using a sample of 98 mixed-gender couples residing in Canada, we used multilevel modeling to examine actor effects (e.g., one's attachment insecurity predicting their own flooding), partner effects (one's attachment insecurity predicting flooding in their partner), and interactions between partners to examine its association with emotional flooding at the third trimester of pregnancy and across early parenthood. Longitudinally, couples were followed from the third trimester to 4 years postpartum to explore how attachment pairings predicted changes in flooding across parenthood. Attachment anxiety in men predicted their own propensity to become flooded during conflict, as well as their partner's flooding. An interaction was seen at the third trimester, such that men who were avoidantly attached reported greater flooding when their partner was high in anxiety compared to low in anxiety. Finally, men's flooding was associated with greater increases over time when high avoidance in men was paired with low avoidance in women, whereas flooding showed the smallest increase when both partners reported low avoidance. Findings suggest that the fit between each partner's attachment styles can improve understanding of the emotional mechanisms experienced during conflict, especially during the often-stressful period of early parenthood.
