There are no reliable epidemiological data in the literature for<unk> . There are numerous challenges with diagnosis, the most relevant of which is the unclear definition of<unk>  within official diagnostic manuals such as the DSM and the ICD, which prevents its identification in the population. Further, there are challenges with diagnostic tools, both for recognition and screening. The altered perception of the<unk>  can only be measured through behavioral tasks delivered individually (See section below). It cannot be measured with questionnaires, or other tools typically used for broad-spectrum investigations. As it is not always present in eating disorders, its prevalence is not comparable to that of anorexia nervosa, bulimia nervosa, and binge eating disorder, and cannot be inferred from them. A negative<unk><unk>  may also be present in other psychiatric conditions such as PTSD, major depression, and<unk>  dysmorphic disorder. Taken together this data suggests the possible presence of perceptual<unk> s in other pathological conditions not directly related to eating disorders. Therefore, the presence of a<unk>  in other psychiatric diseases remains speculation, not yet supported by sufficient literature data, as suggested by Scheffers.
