Body Image Projection Bias in Heterosexual Romantic Relationships: A Dyadic Investigation.

Guided by projection bias perspectives, this article sought to advance understanding of the associations between body image and relationship and sexual satisfaction within heterosexual romantic relationships. Across two studies, both members of heterosexual dating and/or married couples reported on their body image, perceptions of partner's attraction to the self, own attraction toward the partner, and relationship satisfaction. Study 2 also incorporated measures of participants' body mass index (BMI) and sexual satisfaction. Across both studies, women with poorer body image perceived their partner to be less attracted to them (irrespective of their partner's actual attraction to them, or how attracted they were to their partner), which in turn was associated with lower relationship and sexual satisfaction. For men, attraction to their partner was consistently associated with their own relationship satisfaction. Results demonstrate that projection biases are a possible mechanism through which body image is associated with romantic relationship and sexual satisfaction, and hint at the particular relevance of appearance-related projection biases for women's relationship and sexual satisfaction.
