Body dissatisfaction and loneliness are a very widespread, unpleasant experiences for an individual. Body dissatisfaction is a subjective negative assessment of one’s physical appearance, certain body parts and some of its characteristics. Loneliness is a subjective experience which occurs when an individual has a deficient social network, whether qualitatively or quantitatively. In this study loneliness was operationalized as a twodimensional construct, in accordance with Weiss’s (1973, as cited in Russell et al., 1984) typology in which emotional (loneliness in love and loneliness in the family) and social loneliness are differentiated. In previous studies it is assumed that the connection between dissatisfaction with body appearance and loneliness is mediated by social avoidance, in that those who are dissatisfied with their body avoid social interactions, which contributes to the feeling of loneliness. There are few studies that have linked body dissatisfaction and loneliness in a sample of young adults, and when they are linked loneliness is used as a onedimensional construct. Therefore, the aim of this research was to examine the relationship between social and emotional loneliness (loneliness in love and loneliness in the family) on one side, and body satisfaction on the other, and to examine the differences in the mentioned variables with regard to the sex of the students. The research consisted of 88 female and 84 male students. Participant data was collected through an online questionnaire that contained questions about sociodemographic data, items from the Body-Esteem Appearance Subscale from the Body-Esteem Scale for Adolescents and Adults (BESAA) and the Social and Emotional Loneliness Scale (SELSA). The results of the research showed that social loneliness, loneliness in love and loneliness in the family of students are negatively correlated with body satisfaction. There was no significant difference between male and female students in social loneliness, loneliness in love and loneliness in the family. It was also shown that male and female students do not differ significantly in body satisfaction.
