Research on size overestimation among anorexics has failed to control for the effects of actual body size on estimated size. We obtained estimates of the size of 3 body sites from 3 groups: 13 anorexic women; 13 non-eating disordered women matched with the anorexics on actual body size; and 13 non-eating disordered women of average size. The anorexic and size-matched normal subjects did not differ in the extent to which they overestimated their body size, but both displayed significantly greater overestimation than did the subjects of average size. Both groups also estimated the actual size of their body sites to be larger than did average-size normal subjects. These findings illustrate the need for appropriate control procedures when considering body image disturbances among persons with eating disorders, and they raise questions about the psychological significance of disturbances in the perceptual component of body image.
针对厌食症患者体型高估现象的研究未能控制实际体型对估计体型的影响。我们从三组人群中获取了三个身体部位的尺寸估计值：13名厌食症女性；13名在实际体型上与厌食症患者匹配的无饮食失调症女性；以及13名体型正常的无饮食失调症女性。厌食症患者和体型匹配的正常受试者在高估自身体型的程度上没有差异，但二者都比体型正常的受试者表现出显著更高的高估程度。两组受试者还将自己身体部位的实际尺寸估计得比体型正常的受试者更大。这些发现表明，在研究饮食失调者的身体意象障碍时需要采用适当的对照程序，同时也引发了关于身体意象感知成分障碍的心理学意义的问题。
