Body checking (BC) and avoidance behaviors (BA) are the dominant behavioral features of body image disturbances (BID) that characterize most individuals with eating disorders (EDs). Whereas BC can be reliably assessed, a valid assessment tool for BA is lacking, preventing an adequate assessment of BID differences across different EDs (anorexia nervosa, AN; bulimia nervosa, BN; binge eating disorder, BED). A total of 310 women with EDs and 112 nonclinical controls completed measures of BC-, BA- and ED-related symptoms. BA did not differentiate between EDs, whereas BC did: it was highest in AN and BN, and lowest in BED. Multivariate analyses also discriminated AN from BN based on BC. Given that results are of preliminary nature, evidence is promising that EDs can be discriminated from healthy controls and that differential BID profiles for the behavioral component among ED subgroups exist. However, replication of the factor structure remains open within ED subsamples.
身体检查行为（BC）和回避行为（BA）是身体意象障碍（BID）的主要行为特征，大多数饮食失调（ED）患者都有这些特征。虽然BC可以得到可靠评估，但目前缺乏一种用于BA的有效评估工具，这妨碍了对不同饮食失调症（神经性厌食症，AN；神经性贪食症，BN；暴饮暴食症，BED）之间身体意象障碍差异的充分评估。共有310名患有饮食失调症的女性和112名非临床对照者完成了与BC、BA及饮食失调相关症状的测量。BA无法区分不同的饮食失调症，而BC可以：BC在AN和BN中最高，在BED中最低。多变量分析也基于BC区分了AN和BN。鉴于结果具有初步性质，有证据表明饮食失调症可以与健康对照者区分开来，并且在饮食失调症亚组中存在行为成分的不同身体意象障碍特征。然而，在饮食失调症亚样本中，因子结构的复制仍未确定。
