The present research aimed to identify the correlation between rumination, self-esteem and body image among university students, and to investigate whether rumination and self-esteem play a mediating role that impacts on their dissatisfaction with their body image. Participants included a sample of 433 (400 female and 33 male) students from Zagazig University, with a mean age (20.4) year. The research applied Rumination scale (developed by current researchers), Self-esteem scale (translation by current researchers), and the body image scale (Shukair, 2009). The findings reported statistically negative correlation between self-esteem and rumination as well as self-esteem and body image disorder; however, rumination was positively correlated with body image disorder. Furthermore, findings revealed that self-esteem and rumination can contribute to the prediction of body image. Mediation analysis revealed a statistically significant direct negative impact of self-esteem on both rumination and body image. Moreover, rumination mediated the relationship between self-esteem and body image among university students. Findings also revealed that the variables rumination and self-esteem contribute to predicting body image disorder. In the light of the theoretical framework, the results of previous studies, and the results of the current study, recommendations and suggested research are discussed.
