Resum
This study aimed to explore the associations among attachment system type, sexual satisfaction, and
marital satisfaction in adult couples in stable relationships. Participants were 294 couples between the
ages of 20 and 70 years who answered self-administered questionnaires. Hierarchical linear modeling
revealed that the anxiety and avoidance, sexual satisfaction, and marital satisfaction dimensions were
closely related. Specifically, the avoidance dimension, but not the anxiety dimension, corresponded
to lower levels of sexual and marital satisfaction. Moreover, for the sexual satisfaction variable, an
interaction effect was observed between the gender of the actor and avoidance of the partner, which
was observed only in men. In the marital satisfaction dimension, effects were apparent only at the
individual level; a positive relation was found between the number of years spent living together and
greater contentment with the relationship. These results confirm the hypothetical association between
attachment and sexual and marital satisfaction and demonstrate the relevance of methodologies when
the unit of analysis is the couple. (Extraído del documento)
