There is considerable overlap in symptomatology between chronic fatigue syndrome (CFS) and affective disorder. We report a comparison of depressive phenomenology and attributional style between a group of CFS subjects seen in a specialized medical setting, which included a high proportion with depression diagnosed by Research Diagnostic Criteria (RDC), and depressed controls seen in a specialized psychiatric setting. Significant symptomatic differences between the depressed CFS group and depressed controls were observed for features such as self-esteem and guilt as well as attribution of illness. All the CFS groups tended to attribute their symptoms to external causes whereas the depressed controls experienced inward attribution. This may have resulted from differences in the severity of mood disorder between the samples, but it is also suggested that an outward style of attribution protects the depressed CFS patients from cognitive changes associated with low mood but at the expense of greater vulnerability towards somatic symptoms such as fatigue.
慢性疲劳综合征（CFS）与情感障碍在症状学上有相当大的重叠。我们报告了一组在专门医疗环境中就诊的CFS患者与在专门精神科环境中就诊的抑郁症对照组之间抑郁现象学和归因方式的比较。该医疗环境中的CFS患者中有很大比例被研究诊断标准（RDC）诊断为抑郁症。在自尊、内疚以及疾病归因等特征方面，观察到抑郁症CFS组与抑郁症对照组之间存在显著的症状差异。所有CFS组倾向于将其症状归因于外部原因，而抑郁症对照组则经历向内归因。这可能是由于样本之间情绪障碍严重程度的差异，但也有人认为，外向型归因方式可保护抑郁症CFS患者免受与情绪低落相关的认知变化影响，但代价是更容易出现疲劳等躯体症状。
