Body size estimation was studied in 22 patients with bulimia and 20 normal controls. Two methods of body size estimation were used, a distorting television image method (DTIM) and the image marking method (IMM). The subjects estimated body size of a dummy as well as their own body on the DTIM. When estimating body size on the DTIM the bulimics overestimated and the controls underestimated, there being a significant difference between the two groups. There was no difference between the groups when estimating the size of the dummy. On the IMM a significant difference was found between the bulimic and control groups, the bulimics overestimating body size and the controls being more accurate. Marked directional effects were found with the DTIM. The two methods of body size estimation are compared.
对22名神经性贪食症患者和20名正常对照者进行了身体大小估计的研究。采用了两种身体大小估计方法，即扭曲电视图像法（DTIM）和图像标记法（IMM）。受试者在DTIM上估计一个假人的身体大小以及他们自己的身体大小。在DTIM上估计身体大小时，神经性贪食症患者高估，而对照组低估，两组之间存在显著差异。在估计假人的大小时，两组之间没有差异。在IMM上，神经性贪食症组和对照组之间存在显著差异，神经性贪食症患者高估身体大小，而对照组更准确。在DTIM上发现了明显的方向效应。对两种身体大小估计方法进行了比较。
