In this research, we are going to examine the various effects of appearance comparison that occurs in women naturally. We would try to understand the changes in compensatory cognition and behavior in women related to body satisfaction. By the use of ecological momentary assessment, it was found that women who have high body dissatisfaction and eating pathology (EPBH) or high body dissatisfaction (HB), have shown a more enthusiastic appearance as compared to the women having low body dissatisfaction (LB). Excluding this behavior, all women have shown a significant amount of negative emotions and cognitions after upward comparison. They also seemed to be more emphasized on dieting or exercising, and showed an increased amount of eating disordered behavior when they were compared upwardly.
