背景：制定DePaul症状问卷（DSQ）来评估肌痛性脑脊髓炎（ME）和慢性疲劳综合征（CFS）患者的症状学和病例定义实现情况。最近对问卷进行了修订，以改善其心理测量特性，增加其诊断可靠性，并评估病例定义所需的症状。最终的仪器被命名为DSQ-2。目的：本研究旨在评估DSQ-2中新增和修订项目的实用性和可靠性。方法：招募了399名患有ME或CFS的成年人的横断面样本来完成DSQ-2。结果：对DSQ-2的描述性分析表明，新的和修订的项目增强了该工具评估某些症状域和评估最近病例定义的能力。此外，探索性因素分析得出了八个因素的解决方案：运动后不适、认知障碍、发烧和流感、疼痛、睡眠障碍、直立性不耐受、泌尿生殖系统问题和温度不耐受。各因子内的条目均表现出较强的内部一致性信度（Cronbach's alpha = 0.73 ~ 0.91）。结论：这些分析表明DSQ-2对ME和CFS的症状和病例定义的实现提供了更全面和准确的理解。
Background: The DePaul Symptom Questionnaire (DSQ) was developed to assess the symptomatology and case definition fulfillment of individuals with myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS). The questionnaire was recently revised to improve its psychometric properties, increase its diagnostic reliability, and assess symptoms required by case definitions. The resulting instrument was named the DSQ-2.Purpose: The current study sought to evaluate the utility and reliability of the new and revised items in the DSQ-2.Method: A cross-sectional sample of 399 adults with ME or CFS was recruited to complete the DSQ-2.Results: Descriptive analyses of the DSQ-2 suggest that the new and revised items enhance the instrument's ability to assess certain symptom domains and evaluate recent case definitions. Additionally, an exploratory factor analysis resulted in an eight-factor solution: post-exertional malaise, cognitive impairment, fever and flu, pain, sleep disruption, orthostatic intolerance, genitourinary issues, and temperature intolerance. The items within each factor demonstrated strong internal consistency reliability (Cronbach's alphas = .73 - .91).Conclusion: These analyses indicate that the DSQ-2 offers a more thorough and precise understanding ME and CFS symptomology and case definition fulfillment.
