Interpersonal Neurobiology and Couple Relationship Quality: A Longitudinal Model

Interpersonal neurobiology is an interdisciplinary theory that is being used by couple and family therapists. However, more investigation is needed to determine if this theory can accurately explain family relationships over time. In this study, we used the nationally representative National Longitudinal Study of Adolescent to Adult Health (Add Health) dataset to examine key elements of interpersonal neurobiology theory. Using structural equation modeling, we explored how maternal and paternal support and self-acceptance during adolescence are related to emotional stability and adult couple relationship satisfaction 13 years later (N = 7864). Results indicate that self-acceptance and emotional stability are factors that contribute to couple relationship satisfaction. We conclude with clinical implications of this study, including how to use mindfulness practices to promote healthy relationships.
