Chronic fatigue syndrome (CFS) is a poorly understood condition. Possible etiological factors include infectious agents, psychiatric disorders, and personality characteristics. We examined personality dimensions in 30 nondepressed patients with CFS, 20 patients with major depressive disorder (MDD), and 15 healthy controls. On the NEO-FFI, patients with CFS scored significantly lower than healthy controls on the extroversion subscale. On the neuroticism dimension of the Eysenck Personality Questionnaire (EPQ), patients with MDD scored higher than those with CFS, who in turn scored significantly higher than the healthy controls. CFS patients rated themselves as higher on neuroticism and less extroverted when ill than when they were well. Our results suggest that high scores on neuroticism and low scores on extroversion in CFS could be a reaction to chronic illness.
慢性疲劳综合征（CFS）是一种人们了解甚少的病症。可能的病因包括感染因子、精神障碍和人格特征。我们对30名无抑郁症状的慢性疲劳综合征患者、20名重度抑郁症（MDD）患者和15名健康对照者的人格维度进行了研究。在《大五人格问卷简式版》（NEO-FFI）上，慢性疲劳综合征患者在外向性分量表上的得分显著低于健康对照者。在艾森克人格问卷（EPQ）的神经质维度上，重度抑郁症患者的得分高于慢性疲劳综合征患者，而慢性疲劳综合征患者的得分又显著高于健康对照者。慢性疲劳综合征患者在患病时自我评定为神经质程度更高，外向性更低，而在病情好转时则相反。我们的研究结果表明，慢性疲劳综合征患者神经质得分高、外向性得分低可能是对慢性病的一种反应。
