Although there is evidence that childhood perfectionistic traits predate the onset of eating disorders, few studies to date have examined the prevalence and clinical correlates of these traits in patients with anorexia nervosa (AN) and their unaffected sisters. The aim of this work was to study the prevalence of childhood obsessive-compulsive traits in patients with lifetime AN, their unaffected sisters and healthy women. A total of 116 AN patients, 32 healthy sisters and 119 controls were assessed by the EATATE Interview to assess traits such as perfectionism, inflexibility, rule-bound traits, drive for order and symmetry, and excessive doubt and cautiousness. Both self-report and maternal reports were collected. AN patients reported more childhood obsessive-compulsive traits than their healthy sisters and controls. In contrast, no differences between healthy controls and unaffected sisters emerged. In patients with AN, a dose-response relationship was found between the number of childhood obsessive-compulsive traits and psychopathology, including body image distortion, thus indicating that these traits are an important feature to be considered in assessing and treating eating disorders.
尽管有证据表明，儿童时期的完美主义特质先于饮食失调症的发生，但迄今为止，很少有研究调查厌食症患者及其未受影响的姐妹中这些特质的患病率和临床相关性。本研究旨在研究终生患有厌食症的患者、其未受影响的姐妹和健康女性中儿童期强迫特质的患病率。通过 EATATE 访谈，共评估了 116 名厌食症患者、32 名健康姐妹和 119 名对照组，评估了完美主义、僵化、规则主导特质、追求秩序和对称、过度怀疑和谨慎等特质。既收集了自我报告，也收集了母亲报告。厌食症患者报告的儿童期强迫特质比健康姐妹和对照组多。相比之下，健康对照组和未受影响的姐妹之间没有差异。在厌食症患者中，发现儿童期强迫特质的数量与精神病理学之间存在剂量反应关系，包括身体意象扭曲，这表明这些特质是评估和治疗饮食失调症时需要考虑的一个重要特征。
