Relationship Quality and Sexuality: A Latent Profile Analysis of Long-term Heterosexual and LGB Long-term Partnerships

Purpose: Drawing on survey data (N = 7,826) collected in the United Kingdom, Australia, and the United States, this paper examines whether sexual orientation is a differentiating factor in explaining relationship quality and maintenance. Previous research suggests that sexual orientation is not significant in determining relationship satisfaction; however, these analyses have used traditional variable driven approaches, which do not provide an holistic view of the relationship by considering the unique combination of characteristics. Method: In this study, latent profile analyses were used, which is a person-centered approach that allows for identification of different types of long-term relationships. Results: Data suggested that LGB individuals had marginally higher levels of relationship quality compared to their heterosexual counterparts, and sexual orientation was also associated with differing types of long-term relationships. Discussion: These findings are interrogated in more detail, in particular, how sexual orientation is associated with types of long-term relationships and how everyday practices are associated with relationship quality.
