Background: The prevalence of body dysmorphic disorder (BDD) has been reported to increase in recent decades. Therefore, scientific studies should be performed to specify psychological variables, which may contribute to the etiology of this disorder. In this study, we examined the role of body image and perfectionism in predicting BDD symptoms among students. Objective: The aim of this survey was to investigate the role of body image and perfectionism in the prediction of BDD symptoms. Methods: This cross sectional study was performed in 2016 on a sample, including 351 students of Hamadan University of Medical Sciences, who were selected based on the Morgan formula and multistage cluster random sampling. The participants completed the Yale-Brown obsessive compulsive scale modified for BDD (BDD-YBOCS), multidimensional body-self relations questionnaire (MB-SRQ), and Besharat's Tehran multidimensional perfectionism scale (TMPS). The collected data were analyzed by Pearson's correlation test and stepwise regression analysis.
Results and Conclusions:The results of stepwise regression analysis showed that perfectionism and body image could significantly predict BDD symptoms (P < 0.001). Therefore, these variables can be important in the promotion of students' health.
