Fifteen bulimic women (DSM III) and 15 women with no indication of an eating disorder, matched pairwise with respect to age, weight and height, were assessed via a distorting video image technique under four conditions. They were asked to: (1) estimate the width of a water bottle, (2) estimate the width of their own body, (3) repeat those estimates under a condition of reward for high accuracy, (4) focus attention on their bodily sensations and indicate how wide their body felt. While groups did not differ in their estimates under condition 1 (water bottle), significant differences were found between groups under conditions 2, 3 and 4 (own body), the percentage of overestimating being highest when subjects were to indicate how wide their body felt. Results suggest that modalities of perception other than visual are strongly involved in the body image distortion of bulimics.
15名神经性贪食症女性(精神疾病诊断与统计手册第三版)和15名无进食障碍迹象的女性,在年龄、体重和身高方面进行了两两匹配,通过一种扭曲视频图像技术在四种条件下进行评估。她们被要求:(1)估计一个水瓶的宽度,(2)估计自己身体的宽度,(3)在高精度奖励条件下重复这些估计,(4)将注意力集中在身体感觉上,并指出自己感觉身体有多宽。虽然两组在条件1(水瓶)下的估计没有差异,但在条件2、3和4(自己身体)下两组之间发现了显著差异,当受试者指出自己感觉身体有多宽时,高估的百分比最高。结果表明,除视觉之外的感知方式在神经性贪食症患者的身体意象扭曲中起了很大作用。
