这项研究是对慢性疲劳综合征（CFS）患者报告的症状数据的可靠性的调查，在三个回忆时间范围内（过去一周，过去一个月和过去6个月），在两个评估点（每次评估之间间隔1周）。多水平模型分析用于确定最佳回忆时间范围，根据测试-重测信度，对于Fukuda et al.（1994）的每个病例定义症状。结果表明，可靠报告CFS症状的最佳时间范围为6个月，包括咽喉痛、淋巴结痛、肌肉痛、运动后不适、头痛、记忆力/注意力困难和睡眠不佳。对于关节疼痛，最佳时间范围是一个月。对CFS症状评估感兴趣的研究人员需要考虑回忆时间框架，特别是当预期目标是标准化和改进用于可靠和准确诊断这种复杂疾病的方法时。
This study serves as an investigation of the reliability of symptom data as reported by individuals with chronic fatigue syndrome (CFS), across three recall time frames (the past week, the past month, and the past 6 months), and at two assessment points (with 1 week in between each assessment). Multilevel model analyses were used to determine the optimal recall time frame, in terms of test -retest reliability, for each of the Fukuda et al. (1994) case defining symptoms. Results suggested that the optimal time frame for reliably reporting CFS symptoms was six months for sore throat, lymph node pain, muscle pain, post-exertional malaise, headaches, memory/concentration difficulties, and unrefreshing sleep. For joint pain, the optimal time frame was one month. Researchers who are interested in the assessment of CFS symptoms need to take recall time frame into account, especially when the intended goal is to standardize and improve the methods used to reliably and accurately diagnose this complex illness.
