In the present study we examined associations between young women's romantic relationships and their body image. Ninety-five heterosexual couples (women's mean age=22.46 and men's mean age=24.38) participated in this study. We examined young women's satisfaction with their own bodies, their perceptions of their significant others’ satisfaction with their bodies, and their significant others’ actual satisfaction with their bodies using the Contour Drawing Rating Scale women's weight status was assessed using body mass index (BMI). Relationship constructs examined included relationship quality and the length of couples’ romantic relationships. Results indicated that females were more dissatisfied with their bodies than they perceived their significant others to be and were more dissatisfied than their significant others actually were. Analyses further indicated that the longer women had been in a relationship with their significant other, the more likely they were to incorrectly believe that their significant other wanted them to look thinner.
