Relationship quality of partners in heterosexual married, heterosexual cohabiting, and gay and lesbian relationships.

The relationship quality of partners in 44 married, 35 heterosexual cohabiting, 50 gay, and 56 lesbian monogamous couples was studied. Each couple lived together and did not have children living with them. Relationship quality was dimensionalized as love for partner, liking of partner, and relationship satisfaction. Cohabiting partners had the lowest Love for Partner and Relationship Satisfaction scores. Differences were also found among partner types on: barriers to leaving the relationship, alternatives to the relationship, a belief that mindreading is expected in the relationship, masculinity, femininity, androgyny, dyadic attachment, shared decision making, and perceived social support from family. The four partner groups did not differ in psychological adjustment. For each type of partner, love for partner was related to many barriers to leaving the relationship and high dyadic attachment; liking of partner was related to few alternatives to the relationship, high dyadic attachment, and high shared decision making; and relationship satisfaction was related to many attractions, few alternatives, few beliefs regarding disagreement is destructive to the relationship, high dyadic attachment, and high shared decision making. Stepwise multiple regression procedures were used to identify the best set of predictors for each partner type. Results are discussed in the context of existing models of relationship quality.
