A silhouette method, the Body Image Assessment, was used to measure self-evaluation of current and ideal body size in three groups: Ss with with anorexia nervosa (n = 37), Ss with bulimia nervosa (n = 59), and normal control Ss (n = 95). Current and ideal body size measures were contrasted across the three groups using body mass index as a covariate to control for the Ss actual body size. Both eating disorder groups judged current body size to be larger and ideal body size to be thinner relative to control Ss. When actual body size was not statistically controlled, Ss with anorexia nervosa judged current body size to be thinner than did control Ss and Ss with bulimia nervosa. These data illustrate the importance of controlling for actual body size when investigating the self-evaluation of body size.
采用一种轮廓法，即身体意象评估法，对三组人群当前和理想体型的自我评估进行测量：神经性厌食症患者（n = 37）、神经性贪食症患者（n = 59）和正常对照者（n = 95）。以体重指数作为协变量来控制被试的实际体型，对三组人群当前和理想体型的测量结果进行对比。与对照组相比，两个饮食失调组均认为自己当前的体型更大，而理想体型更瘦。当未对实际体型进行统计学控制时，神经性厌食症患者认为自己当前的体型比对照组和神经性贪食症患者更瘦。这些数据表明，在研究体型自我评估时，控制实际体型非常重要。
