Numerous studies emphasize the increasing prevalence of eating disorders and the negative consequences associated with such disorders. In order to better understand the factors that are related to their development and that need to be acted upon during the prevention and treatment of the disorder, this study examined the role of environmental and contextual factors (perceived support from one's own family, perceived socio-cultural pressure, internalization of thinness ideals) in explaining the psychopathology of feeding. More specifically, it was examined whether the aforementioned variables predict disordered eating habits and weight concerns, which represent the main factors that indicate the risk of eating disorders. Also, the existence of a mediating effect of perceived socio-cultural pressure and internalization of thinness ideals in the relationship between perceived family support and disordered eating habits and weight concerns was examined. 211 participants participated in the research, which was intended for women between the ages of 18 and 30. The survey was conducted online, through a Google form, and the collection of participants was conducted on social networks, where a link to the survey was published. The obtained results indicate that, after controlling BMI, lower perceived support from one's own family, higher perceived socio-cultural pressure and higher internalization of the ideal of thinness predict more disordered eating habits and more concern about weight. Also, based on the results, the existence of a mediating effect was established in the relationship between perceived family support and disordered eating habits and concern about weight, whereby perceived socio-cultural pressure proved to be a significant mediator, while the internalization of thinness ideals was not. The described results are important in order to expand the theoretical basis on the causes of eating disorders, and the obtained conclusions can be used in their prevention and treatment.
