Towards an integrative attachment-based model of relationship functioning.

Based on attachment theory, this study developed a theory-based model of heterosexual relationship functioning that examined both proximal and distal factors and both actor and partner effects. A particular focus was on the underexplored issue of double-mediated effects between attachment orientation and relationship satisfaction. Data were collected from a community sample of 95 cohabiting and married couples with a mean age of 39.30 years. Participants completed measures of attachment, commitment, provision of partner support, trust, intimacy, destructive conflict management, and relationship satisfaction. The hypothesized model was largely supported. The association between attachment orientation and relationship satisfaction was mediated through a series of actor and partner variables. No gender differences were found across actor paths; however, differences were found in partner effects for men and women. The model has important implications for relationship researchers and practitioners.
