Then psychometric properties of the scale were studied in a sample of women with eating disorders who were selected by convenient sampling method. Data collecting tools were BSQ-C8, BSQ-34, Body Dysmorphic Meta Cognition Questionnaire (BDMCQ), and Yale-Brown Obsessive Compulsive Scale for Body Dysmorphic Disorder (YBOCS–BDD). To analyze data by SPSS version 16, correlation coefficient, Cronbach’s alpha, split half coefficient, and ROC curve were used. Results In the sample of women with eating disorders the coefficients of Cronbach's alpha and split-half were 0.79 and 0.74, respectively. Concurrent validity by way of correlation between the scale and BSQ-34, YBOCS–BDD, and BDMCQ were 0.91, 0.59 and 0.58, respectively. Sensitivity, specificity, and the cut point of this questionnaire were 0.80, 0.67 and 26.5, respectively.
