Chronic fatigue syndrome (CFS) is an illness characterised by fatigue and other symptoms. Both psychological and biological aetiological factors have been proposed, but the disorder is of uncertain origin. The aetiology of the symptoms is therefore ambiguous. It has been suggested (a) that patients with CFS tend to interpret their symptoms as indicating physical illness and (b) they tend not to interpret these symptoms in terms of negative emotion. In order to test these hypotheses we developed a self-report questionnaire to assess the interpretation of symptoms in patients with CFS. It was administered to patients with CFS, patients with depression, patients with multiple sclerosis (MS), and normal controls. Preliminary results suggest that the measure has acceptable psychometric properties. Patients with CFS were more likely than either depressed patients or normal controls to interpret symptoms (characteristic of CFS) in terms of physical illness, but did not differ in this from the MS patients. When compared with all three other groups (including the MS patients), the patients with CFS were least likely to interpret symptoms in terms of negative emotional states. The theoretical and clinical implications of the findings are discussed.
慢性疲劳综合征（CFS）是一种以疲劳及其他症状为特征的疾病。心理和生物学病因都曾被提出，但该病症的起源尚不确定。因此，这些症状的病因尚不明确。有人提出：（a）慢性疲劳综合征患者倾向于将自身症状解读为身体疾病的表现；（b）他们往往不会从负面情绪的角度去解读这些症状。为了验证这些假设，我们设计了一份自我报告问卷，以评估慢性疲劳综合征患者对症状的解读。该问卷被发放给慢性疲劳综合征患者、抑郁症患者、多发性硬化症（MS）患者以及正常对照组。初步结果表明，该测量方法具有可接受的心理测量特性。与抑郁症患者或正常对照组相比，慢性疲劳综合征患者更倾向于将（慢性疲劳综合征特有的）症状解读为身体疾病，但在这方面与多发性硬化症患者并无差异。与其他三组（包括多发性硬化症患者）相比，慢性疲劳综合征患者最不可能从负面情绪状态的角度去解读症状。本文讨论了这些研究结果的理论和临床意义。
