Abstract

Some females are at an increased risk of developing bulimia. However, etiological factors and their interplay remain controversial. The present study analyzed Sticefe Model for eating disorders in a non-clinical population by examining gender differences with respect to the following risk factors: body mass index (BMI), body dissatisfaction, perceived social pressure to be thin, body-thin internalization, and dieting behavior. A sample of 162 American college students (64 males and 91 females) was surveyed, and validated scales were used. The Sticey model was tested using Structural Equation Modeling. Our results supported Stice r Dual Pathway Model of bulimic pathology for females but not for males. Females reported significantly higher body dissatisfaction, perceived pressure to be thin and weight-loss oriented behaviors than males (p < .05), but no gender differences were found in their degree of body thin internalization (p > .05), a key predictor of body dissatisfaction (r = .33; p < .01). Participants with higher BMI reported greater social pressure to be thin than those with lower BMI (p < .05). However, females engaged in dietary restraint, the main risk factor for eating disorders, regardless of their BMI (p > .05) although their BMI was significantly lower than males (d = 0,51). The results of this study fail to support the role of BMI as a predictor of dietary restraint in females, the main risk factor of eating disorders. Males may abstain from dietary restraint to gain muscular volume and in turn increase their BMI. Implications are discussed.
