Background: Eating disorder is a common problem in teenage girls and young women. In clinical situations, brief screening is necessary to recognize the patients. The present research aimed to evaluate the psychometric properties of Eating Disorder Diagnostic Scale (EDDS).
Methods: The study sample included 431 females selected from among the females referring to Shiraz’s sport clubs using convenience sampling. The participants in this research responded to the EDDS that was translated by the researcher and their BMI index was calculated.
Results: The internal consistency coefficients, and Spearman-Brown and Guttmann spilt-half correlations were 0.84, 0.82 and 0.83, respectively.  The findings showed that the agreement rate of the instrument with the clinician’s diagnosis and confirmatory factor analysis, and the correlation between each question and the whole score were appropriate.
Conclusion: In general, the results of this research showed that the Persian version of Eating Disorder Diagnostic Scale (EDDS) has appropriate validity and reliability and can be used in clinical and research situations for the assessment of eating disorder.
