“…Unfortunately, no further current norms with a same aged German population are available [27]. Considering other international norms neither seemed to appropriate as there is evidence that the use of norms from different nations might result in a misinterpretation of findings [42]. Fifth, the recruitment of the current sample was carried out in 2010 and we compared the observed EDI scores with a population-based sample published in 2005 [31].…”

The goal of this study was to compare data for women with bulimia nervosa and for a healthy control group both in Japan and Germany. These data were obtained using the Eating Disorder Inventory (EDI-2). In Germany, EDI-2 data and BMI values were collected from 102 nurses in training, 57 female medical students, and 29 patients with bulimia nervosa. In Japan, data were gathered from 243 female 'short college' students and 20 patients with bulimia nervosa. The Japanese non-clinical control group showed significantly higher values on nearly all EDI scales than the German control group. They had a markedly higher drive for thinness, though their BMI values were lower. When the German and the Japanese bulimia nervosa patients were compared, the Japanese patients also showed higher values than their German counterparts on three EDI scales, but these differences were negligible. It is suggested that sociocultural factors in Japan, in particular a significant dependency on social norms, may contribute to the high EDI values.

“…10 Indeed, norms for this construct appear to vary across even culturally similar populations. 66,67 In addition to the cultural relevance of specific item content, response style 10 -which can also be culturally drivenmay have contributed to cross-population differences. A third advantage would be improved detection of NFP-AN in clinical and community settings by encouraging the use of screening instruments that do not require fat phobia for diagnosis.…”

Objective: Cross-cultural data suggest that rationales for food refusal vary in anorexia nervosa (AN), and a variant, termed non-fat-phobic AN (NFP-AN), has been described. This review evaluates whether data support modification of the requirement for intense fear of weight gain to meet AN criterion B in DSM-V.Method: We performed a systematic search of the Medline and PsychInfo literature and evaluated the relevant publications by Robins and Guze's (Am J Psychiatry 126, [983][984][985][986][987] 1970) criteria as a standard for diagnostic validity. We also performed a meta-analysis comparing the severity of eating pathology in AN to (a) NFP-AN and (b) AN with low drive for thinness (low-DT-AN).Results: A modest literature indicates that NFP-AN has wide geographic distribution and occurs in both Western and non-Western populations alongside cases of typical AN. Aggregating across eligible studies, patients with NFP-AN or low-DT-AN score at least 2/3 of a standard deviation lower on measures of eating pathology than patients with conventional AN. Transcultural comparison of drive for thinness suggests significantly lower norms in non-Western cultures.Discussion: NFP-AN occurs with wide distribution. Further research is necessary on the course and outcomes of NFP-AN to characterize its congruence with, or distinction from, conventional AN. We discuss several options for including a description of NFP-AN in DSM-V. V

Norms, normality, and clinical significant change: Implications for the evaluation of treatment outcomes for eating disorders

Abstract: Neglecting differences in national norms can lead to substantial misinterpretation of empirical findings in the diagnosis of eating disorders and the evaluation of treatment outcome.
