To examine differences in body size estimation in adolescents with different types of eating disorders.
A total of 129 patients with eating disorders (M(age) = 16.0 +/- 1.8) and 354 healthy control participants (CP) (M(age) = 15.2 +/- 2.1) completed the EDI-2 and were asked to estimate the circumference of selected body parts by using string (BID-CA).
CP showed an average overestimation of 8-16%, depending on the estimated body part. Eating disorder patients overestimated their body parts on average by about 30%. Thigh and waist estimations were the best variables for discriminating between patients with eating disorders and CP. No significant differences were found between bulimia nervosa and anorexia nervosa patients.
Body image distortion plays an important role in both anorexia nervosa and bulimia nervosa. The BID-CA is well suited to discriminate between healthy and disordered overestimation of body parts.
研究不同类型进食障碍青少年在体型估计方面的差异。
共有 129 名进食障碍患者（M（年龄）= 16.0 +/- 1.8）和 354 名健康对照组参与者（CP）（M（年龄）= 15.2 +/- 2.1）完成了 EDI-2 并被要求使用绳子（BID-CA）估计选定身体部位的周长。
CP 对估计的身体部位的平均高估了 8-16%，取决于估计的身体部位。进食障碍患者对自己身体部位的平均高估了约 30%。大腿和腰围的估计是区分进食障碍患者和 CP 的最佳变量。在神经性贪食症和神经性厌食症患者之间未发现显著差异。
身体形象扭曲在神经性厌食症和神经性贪食症中都起着重要作用。BID-CA 非常适合区分健康和紊乱的身体部位高估。
