Attachment, emotion regulation, and well-being in couples: Intrapersonal and interpersonal associations

There is a well-established link in the literature between secure romantic attachment orientation and psychological well-being. The underlying processes of this link and the couple interplay between attachment and well-being are notably less explored. Using a dyadic framework, this study examines both couple members' emotion regulation strategies as potential mediators of this link.

One hundred and nineteen heterosexual couples completed self-report measures on attachment style, psychological well-being, tendency to suppress emotions, and emotion expression. Analyses were performed using the actor-partner interdependence mediation model that distinguishes between intrapersonal and interpersonal influences.

Results showed that controlling for relationship length, there was an intrapersonal indirect effect of attachment avoidance on psychological well-being through emotion suppression. Moreover, interpersonal indirect effects were found (a) with individual attachment avoidance being associated with partner's psychological well-being through own emotion expression and (b) individual's attachment anxiety being associated with partner's psychological well-being through both own's emotion expression and partner's emotion suppression.

These findings highlight the complex associations among attachment, emotion regulation, and well-being and point out the role of emotion regulation as a potential underlying pathway explaining these associations. The results suggest the importance of considering the relational nature of emotional and attachment dynamics in couples.
