Abstract
It is widely documented that negative body image is a significant public health concern due to its association with symptoms of disordered eating and worse psychological well-being. The purpose of the study was to develop a path model of intrapersonal dimensions (self-efficacy and internal locus of control) as antecedents of perceived stress toward females' body dissatisfaction and eating attitude disorders. A total of 300 females, including 100 aspiring fashion models, 100 athletes and 100 students (controls), between 15 and 24 years of age (M = 19.6, SD = 1.85) participated in the study. Measures included level of psychological stress, self-efficacy and locus of control dimensions, body dissatisfaction and eating attitude disorder indices. A path analysis confirmed our research hypothesis. Comparing the three subsamples, we found better fit indexes in the two subgroups with elevated investment on their body image with respect the control group. More specifically, the model in the group of aspiring fashion models showed the best fit index. These results indicated that aspiring fashion models have a strong desire to maintain their low body mass or to become thinner. For this reason, a suitable involvement of expert health workers in the nutritional and psychological field could be extremely essential in the fashion world to maintain a healthier well-being.
