Abstract

When forming a relationship, people can to some extent include their partner’s resources, perspectives and identities in their own identity (i.e., inclusion of the other in the self, or IOS). In this study, which was conducted with 169 couples, we examine the association of three sources of IOS: (a) the IOS of one member of the relationship; (b) the IOS of their partner; and (c) the similarity of both partners’ IOS with indicators of relational quality (partner conflicts, satisfaction with the relationship and sexual satisfaction) and quality of life (life satisfaction and stress). Using a multilevel approach, the results showed that higher IOS was related to higher levels of relational quality in the person and their partner, and with higher levels of quality of life in the person but not in their partner. Likewise, couples showed a strong similarity in IOS, which was indicative of higher relational quality and quality of life. These results underscore the importance of analysing the (inter)personal mechanisms and their consequences at different levels (i.e., individual and couple).
