Hi Mojgan,

Consider contacting Dr. Sing Lee at The Chinese University of Hong Kong. He specializes in eating disorders and has published widely in them.

China: Lee, Sing, Lee, Antoinette M., Leung, Tony, & Yu, Hong. (1997). Psychometric properties of the Eating Disorders Inventory (EDI-1) in a nonclinical Chinese population in Hong Kong. The International Journal of Eating Disorders, 21(2), 187.

China: Lee, Sing, Leung, Tony, & Lee, Antoinette M. (1998). Cross-cultural validity of the eating disorder inventory: A study of Chinese patients with eating disorders in Hong Kong. International Journal of Eating Disorders, 23(2), 177-188.

Zimbabwe: Hooper, M., & Garner, D. (1986). Application of the eating disorders inventory to a sample of black, white, and mixed race schoolgirls in Zimbabwe. International Journal of Eating Disorders, 5(1), 161-168.

Not sure how helpful the Bulgarian and Zimbabwe articles will be - but the Chinese articles should give you some nice norms (as Stephen suggested above)!
