Personality disorders are common in eating disorders and preliminary reports indicate that this type of disorders implicate a poor prognosis in anorexia and bulimia nervosa. Cluster C personality disorders, particularly avoidant and dependent personality disorder are the most frequent in anorexia nervosa. In bulimia nervosa, however, cluster B personality disorders, including borderline and histrionic personality disorders, are more frequent. Furthermore, temperament could differentiate anorectic patients from bulimic patients. Eating disorders seem to be associated with high scores in neuroticism and harm avoidance. However, while anorexia nervosa patients might have higher persistence, bulimia nervosa patients seem to have an impulsive temperament. According to the character model of Cloninger, both anorexia and bulimia present lower scores in the dimension self-directedness.
人格障碍在饮食失调中很常见，初步报告表明，这类障碍意味着神经性厌食症和神经性贪食症的预后不良。C类人格障碍，尤其是回避型和依赖型人格障碍，在神经性厌食症中最为常见。然而，在神经性贪食症中，B类人格障碍，包括边缘型和表演型人格障碍，更为常见。此外，气质可以区分神经性厌食症患者和神经性贪食症患者。饮食失调似乎与神经质和回避伤害得分高有关。然而，虽然神经性厌食症患者可能有更高的坚持性，但神经性贪食症患者似乎有一种冲动的气质。根据克隆宁格的性格模型，神经性厌食症和神经性贪食症在自我导向维度上的得分都较低。
