Understanding how patients with chronic fatigue syndrome (CFS) recall their fatigue is important because fatigue is a core clinical dimension of this poorly understood illness.
This study assessed the associations between momentary fatigue ratings and weekly recall of fatigue in 71 participants with CFS.
During the three-week data collection period, fatigue intensity was recorded six times a day in electronic diaries. At the end of each week, participants were asked to recall their fatigue intensity for that week. Statistical analyses were done with t-tests and Pearson's and intraclass correlations.
Average weekly recall of fatigue intensity was significantly higher than average momentary ratings. Furthermore, moderate to high Pearson's correlations and intraclass correlations (consistency and absolute agreement) between recall and momentary fatigue ratings were found.
Individuals with CFS recalled consistently higher levels of fatigue in comparison to real-time momentary ratings, yet the level of agreement between the two measures was moderate to high. These findings may have implications for the conduct of office examinations for CFS.
了解慢性疲劳综合征（CFS）患者如何回忆他们的疲劳情况很重要，因为疲劳是这种了解甚少的疾病的核心临床维度。
本研究评估了71名CFS参与者的瞬时疲劳评分与每周疲劳回忆之间的关联。
在为期三周的数据收集期内，每天通过电子日记记录6次疲劳强度。在每周结束时，要求参与者回忆该周的疲劳强度。采用t检验、Pearson相关性分析和组内相关性分析进行统计分析。
疲劳强度的每周平均回忆显著高于平均瞬时评分。此外，还发现回忆与瞬时疲劳评分之间存在中度至高的Pearson相关性和组内相关性（一致性和绝对一致性）。
与实时瞬时评分相比，CFS患者回忆的疲劳水平始终较高，但两种测量方法之间的一致性水平为中度至高。这些发现可能对CFS的门诊检查有影响。
