Methods: This study was carried out on 273 students, selected through convenient sampling method, in Kermanshah University Medical of Science. The BSQ-34 was translated into Persian. Data collection tools were BSQ-34 and Appearance Schema Inventory (ASI). The data were analyzed by SPSS-16 software using Spearman correlation coefficient, factor analysis, Cronbach’s alpha and Guttman split-half correlation.

Results: The coefficients of Cronbach’s alpha, split-half and test-retest reliability were 0.95, 0.93 and 0.82, respectively. The correlation coefficient of this questionnaire with Appearance Schema Inventory (ASI) was 0.63. The results of factor analysis showed 6 factors accounted for 61.87% of the questionnaire variance in total.
