This study uses novel biometric figure rating scales (FRS) spanning body mass index (BMI) 13.8 to 32.2 kg/m and BMI 18 to 42 kg/m . The aims of the study were (i) to compare FRS body weight dissatisfaction and perceptual distortion of women with anorexia nervosa (AN) to a community sample; (ii) how FRS parameters are associated with questionnaire body dissatisfaction, eating disorder symptoms and appearance comparison habits; and (iii) whether the weight spectrum of the FRS matters. Women with AN (n = 24) and a community sample of women (n = 104) selected their current and ideal body on the FRS and completed additional questionnaires. Women with AN accurately picked the body that aligned best with their actual weight in both FRS. Controls underestimated their BMI in the FRS 14-32 and were accurate in the FRS 18-42. In both FRS, women with AN desired a body close to their actual BMI and controls desired a thinner body. Our observations suggest that body image disturbance in AN is unlikely to be characterized by a visual perceptual disturbance, but rather by an idealization of underweight in conjunction with high body dissatisfaction. The weight spectrum of FRS can influence the accuracy of BMI estimation. Copyright © 2017 John Wiley & Sons, Ltd and Eating Disorders Association.
本研究使用了新型生物特征体型评定量表（FRS），其涵盖的体重指数（BMI）范围为13.8至32.2kg/m²以及18至42kg/m²。该研究的目的包括：（i）将神经性厌食症（AN）女性的FRS体重不满和感知扭曲与社区样本进行比较；（ii）FRS参数如何与问卷中的身体不满、饮食失调症状及外貌比较习惯相关联；以及（iii）FRS的体重范围是否重要。患有AN的女性（n = 24）和社区女性样本（n = 104）在FRS上选择了她们当前和理想的体型，并完成了额外的问卷。患有AN的女性在两个FRS中都准确地挑选出了与她们实际体重最相符的体型。对照组在FRS 14 - 32中低估了她们的BMI，而在FRS 18 - 42中则是准确的。在两个FRS中，患有AN的女性都希望拥有接近她们实际BMI的体型，而对照组则希望拥有更瘦的体型。我们的观察结果表明，AN中的身体形象障碍不太可能以视觉感知障碍为特征，而更可能是由对体重过轻的理想化以及高度的身体不满所导致。FRS的体重范围会影响BMI估计的准确性。版权所有© 2017约翰·威利父子有限公司和饮食失调协会。
