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.
The current study sought to evaluate the utility and reliability of the new and revised items in the DSQ-2.
A cross-sectional sample of 399 adults with ME or CFS was recruited to complete the DSQ-2.
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).
These analyses indicate that the DSQ-2 offers a more thorough and precise understanding ME and CFS symptomology and case definition fulfillment.
德保罗症状问卷（DSQ）旨在评估肌痛性脑脊髓炎（ME）和慢性疲劳综合征（CFS）患者的症状表现及病例定义符合情况。该问卷最近进行了修订，以改善其心理测量特性，提高其诊断可靠性，并评估病例定义所要求的症状。修订后的问卷被命名为DSQ - 2。
本研究旨在评估DSQ - 2中新的和修订后的条目是否实用且可靠。
招募了399名患有ME或CFS的成年人作为横断面样本，完成DSQ - 2。
DSQ - 2的描述性分析表明，新的和修订后的条目增强了该问卷评估某些症状领域以及评价最新病例定义的能力。此外，探索性因素分析得出了一个八因素模型：运动后不适、认知障碍、发热和流感症状、疼痛、睡眠障碍、体位性不耐受、泌尿生殖系统问题以及体温不耐受。每个因素中的条目都显示出很强的内部一致性信度（克隆巴赫α系数 = 0.73 - 0.91）。
这些分析表明，DSQ - 2能更全面、精确地理解ME和CFS的症状表现及病例定义符合情况。
