There were 174 Spanish heterosexual couples with a mean length of relationship of 13.9 years who participated in the study. The hypotheses were tested according to the actor-partner interdependence model. We proposed a model in which PA and NA could mediate the association between attachment insecurities and life and relationship satisfaction. Results show that (1) actor effects are more frequent than partner effects; (2) anxious attachment tends to be related to NA and avoidant attachment to PA; (3) avoidance is more detrimental than anxiety for relationship satisfaction at individual and dyadic levels, and (4) there are some mediational effects of NA and PA in the association between attachment insecurities and life and relationship satisfaction.enAtribución-NoComercial-SinDerivadas 4.0 Internacionalinfo:eu-repo/semantics/openAccessartículo
