Body dissatisfaction refers to negative thoughts and feelings that individuals may have about their own body and appearance. Body dissatisfaction is related to the way people think and behave in a romantic relationship. In this research, a romantic relationship is defined as a close relationship between only two partners. Aspects of romantic relationships that were examined in this study include: relationship satisfaction, relationship esteem, relationship depression, fear of intimacy, relationship anxiety, relationship monitoring, relationship preoccupation, relationship consciousness, relationship motivation, internal relationship control, external relationship control and relationship assertiveness. The aim of this research was to examine the relation between body dissatisfaction and certain aspects of romantic relationships among men and women. The study involved 302 participants aged 20 to 58, with 177 (58.6%) being women and 125 (41.4%) being men. The results indicate that gender does not moderate the relationship between body dissatisfaction and the expression of aspects of a romantic relationship. Nevertheless, gender and body satisfaction are independent predictors of the expression of certain aspects in a romantic relationship. Specifically, men tend to exhibit lower levels of relational anxiety and depression. Conversely, women are more likely to exhibit higher relationship satisfaction, relationship assertiveness and have a heightened relationship consciousness. Furthermore, individuals who are more satisfied with their physical appearance tend to exhibit greater relationship esteem, possess a stronger internal locus of control, demonstrate less relationship monitoring and a reduced fear of intimacy, as well as less relational depression and anxiety, regardless of gender. The lack of moderational effects of gender on the tested relationship can be explained by the majority of young participants, the change in gender roles and the importance of body dissatisfaction as it is.
