Three current techniques for estimating body size (Image Marking, Visual Size Estimation, and Distorting Video techniques) were compared. Anorexia nervosa and bulimic patients and normal control subjects were required to make size judgments of the way they 'knew' they looked, the way they 'felt' they looked, and of the width of an inanimate control object. Results from the three techniques were not the same, thus implying that research findings can no longer be cross-compared. Moreover, while all subjects were similar in the accuracy of their estimation of a control object, anorexia nervosa and bulimic patients overestimated their own body size significantly more than normal controls. This difference was even more marked when affective instructions were compared.
对三种当前用于估计身体尺寸的技术（图像标记、视觉尺寸估计和扭曲视频技术）进行了比较。要求神经性厌食症患者、贪食症患者和正常对照受试者对他们“认为”自己的样子、“感觉”自己的样子以及一个无生命对照物体的宽度进行尺寸判断。三种技术的结果并不相同，这意味着研究结果不能再进行交叉比较。此外，虽然所有受试者对对照物体的估计准确性相似，但神经性厌食症患者和贪食症患者对自己身体尺寸的高估明显超过正常对照组。当比较情感性指令时，这种差异更加明显。
