The Persian Version of Eating Disorder Examination Questionnaire and Clinical Impairment Assessment: Norms and Psychometric Properties for Undergraduate Women

OBJECTIVE: The aim of this study was to provide norms of Eating Disorder Examination Questionnaire (EDE-Q) and Clinical Impairment Assessment (CIA) for undergraduate women in Iran. MATERIALS AND METHODS: Undergraduate women (N = 516) completed the EDE-Q, CIA, and the Binge Eating Scale (BES). RESULTS: Average score, standard deviation, and percentile rank of EDE-Q and its subscale as well as CIA were reported. In addition, the frequency of key eating disordered behaviors was presented. Both EDE-Q and CIA demonstrated strong internal consistency. In addition to the significant correlation between the EDE-Q and CIA (0.59), they both showed a moderate to strong correlation with the BES (r = 0.33 to 0.61). The EDE-Q and CIA successfully differentiated underweight, normal weight, and overweight women. Moreover, women who reported higher level of restraint or regular binge eating episodes obtained higher score on the CIA than women who did not have such behaviors across the same period. CONCLUSION: This study provided preliminary support for the reliability and validity of the Persian version of the EDE-Q and CIA. The obtained norms for the EDE-Q and the CIA are helpful in clinical practice and intercultural studies of eating disorders.
