Drive for thinness is a cardinal feature of bulimia nervosa. However, the widely used Drive for Thinness (DFT) subscale of the Eating Disorder Inventory (Garner, 2004; Garner, Olmstead, & Polivy, 1983) appears to measure a desire to be thinner, not a desire to be objectively thin. We developed the Drive for Objective Thinness (DFOT) Scale and compared unrestrained and restrained eaters and those with bulimia nervosa on the DFT subscale, Goldfarb's Fear of Fat Scale (GFFS; Goldfarb, Dykens, & Gerrard, 1983), and the DFOT Scale. Restrained eaters had higher scores than unrestrained eaters on the DFT subscale and the GFFS, but both groups had low scores on the DFOT Scale. Only the group with bulimia nervosa showed elevated scores on the DFOT Scale. We conclude that restrained eaters diet mostly to avoid weight gain, that individuals with bulimia nervosa diet to achieve thinness and avoid fatness, and that the drive for objective thinness is a unique feature of bulimia nervosa.
追求苗条是神经性厌食症的一个主要特征。然而，广泛使用的饮食失调问卷（Garner，2004；Garner、Olmstead 和 Polivy，1983）中的“追求苗条”（DFT）分量表似乎测量的是变瘦的欲望，而不是客观上变瘦的欲望。我们开发了“追求客观苗条”（DFOT）量表，并将无约束和约束性进食者以及神经性厌食症患者与 DFT 分量表、Goldfarb 的“对脂肪的恐惧量表”（GFFS；Goldfarb、Dykens 和 Gerrard，1983）和 DFOT 量表进行了比较。无约束性进食者在 DFT 分量表和 GFFS 上的得分高于约束性进食者，但两组在 DFOT 量表上的得分都较低。只有神经性厌食症患者在 DFOT 量表上表现出较高的得分。我们得出结论，约束性进食者主要通过节食来避免体重增加，神经性厌食症患者通过节食来达到苗条和避免肥胖，而追求客观苗条是神经性厌食症的一个独特特征。
