本研究旨在验证肌痛性脑脊髓炎/慢性疲劳综合征（ME/CFS）症状的综合自我报告测量，以帮助临床和研究评估。探索性因素分析 (EFA) 用于使用特征明确的个体样本（92.6% 符合和/或加拿大临床标准）建立德保罗症状问卷 (DSQ) 的基本因素结构，然后利用验证性因素分析 (CFA) 在不太严格招募的个体样本上测试该结构。还利用症状学和功能的替代测量方法检查了 DSQ 的收敛和判别有效性。使用 EFA（神经内分泌、自主和免疫功能障碍；神经/认知功能障碍；劳力后不适）找到了 3 因素解决方案，并且该因素结构的拟合对于第二个样本来说是足够的。 DSQ 是 ME/CFS 症状的有效测量方法。出现的因素与之前关于症状群的文献一致，并且建立了收敛效度和判别效度。
The present study sought to validate a comprehensive self-report measure of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) symptomatology to aid in clinical and research assessment. Exploratory factor analysis (EFA) was used to establish the underlying factor structure of the DePaul Symptom Questionnaire (DSQ) using a well-characterized sample of individuals (92.6% met the and/or the Clinical Canadian Criteria), and this structure was then tested on a less stringently recruited sample of individuals utilizing a confirmatory factor analysis (CFA). Convergent and discriminant validity of the DSQ were also examined utilizing alternative measures of symptomatology and functioning. A 3-factor solution was found using EFA (Neuroendocrine, Autonomic & Immune Dysfunction; Neurological/Cognitive Dysfunction; Post-Exertional Malaise) and the fit of this factor structure was adequate for the second sample. The DSQ is a valid measure of ME/CFS symptomatology. The emergent factors were consistent with previous literature on symptom clusters, and convergent and discriminant validity were established.
