The question whether anorexia nervosa (AN) and bulimia nervosa (BN) are different disorders or the extremes of a psychopathologic spectrum still has no definite answer. A way to face this problem is to examine the personality traits underlying these disorders.
The Temperament and Character Inventory (TCI) was administered to 141 anorectics (70 Restrictor and 71 Binge-purging), to 102 bulimics, and to 100 controls. The Temperament and Character Inventory main scales are Novelty Seeking, Harm Avoidance, Reward Dependence, Persistence, Self-Directedness, Cooperativeness, and Self-Transcendence.
The personality profiles that emerged are characterized by low Novelty Seeking, high Harm Avoidance, high Persistence, and low Self-Directedness in AN, and by high Novelty Seeking, high Harm Avoidance, and low Self-Directedness in BN. Binge-purging anorectics showed a personality profile midway between anorectics and bulimics.
The dimensional study of personality through the TCI and its facets seems effective in discriminating the personality traits underlying the different subtypes of Eating Disorders. The hypothesis of an Eating Disorders spectrum and its clinical implications are discussed.
神经性厌食症（AN）和神经性贪食症（BN）究竟是不同的疾病，还是精神病理谱的两端，这个问题仍没有明确答案。解决这一问题的一个方法是研究这些疾病背后的人格特质。
对141名厌食症患者（70名节食型和71名暴饮暴食-清除型）、102名贪食症患者和100名对照组进行气质性格量表（TCI）测试。气质性格量表的主要分量表包括寻求新奇、避免伤害、奖赏依赖、坚持性、自我导向、合作性和自我超越。
所呈现出的人格特征为，神经性厌食症患者表现为低寻求新奇、高避免伤害、高坚持性和低自我导向，神经性贪食症患者表现为高寻求新奇、高避免伤害和低自我导向。暴饮暴食-清除型厌食症患者的人格特征处于厌食症患者和贪食症患者之间。
通过气质性格量表及其各个方面对人格进行维度研究，似乎能有效区分不同类型饮食失调背后的人格特质。文中讨论了饮食失调谱的假设及其临床意义。
