Abstract

BACKGROUND: The quality of interpersonal ties-especially closer relationships-appears to be associated with physical health outcomes. Sleep is one pathway through which relationships and health appear to be linked, but this has been inadequately investigated in the context of dyadic attachment.

PURPOSE: The present study examined links between relationship-specific attachment anxiety (which can involve preoccupation with one's partner, negative relationship cognitions, and fear of abandonment) and avoidance (e.g., low emotional investment or intimacy) and sleep quality.

METHODS: Attachment, assessed using the Experience in Close Relationship (ECR), was used to predict Pittsburgh Sleep Quality Inventory (PSQI)-assessed sleep quality in 92 married heterosexual couples via actor-partner interdependence models. Depression was examined as a potential mediator of this association.

RESULTS: Consistent with hypotheses, actors' anxious attachment predicted diminished quality of their own sleep, whereas actors' avoidant attachment was unrelated to their own sleep quality.

RESULTS further suggested that couples in which both spouses were higher in attachment anxiety experience better sleep quality (b = -0.74, SE = 0.28, p =.0082, 95% CI [-1.287, -0.196]). Conversely, couples in which both spouses were higher in attachment avoidance showed poorer sleep quality (b = 0.56, SE = 0.23, p =.0188, 95% CI [0.095, 1.016]). These effects were found to be independent of marital satisfaction and depression. Some evidence was also consistent with mediation of links between attachment and sleep quality via depression.

CONCLUSIONS: Results suggest adult romantic attachment and sleep are associated in complex ways, highlighting the importance of dyadic approaches to the study of relationships, sleep, and health.
