Recalled evaluation of headache intensity is often affected by several factors. Recently, computerized ecological momentary assessment (EMA) has been developed to avoid such problems as recall bias. Here, we compared recalled headache intensity with momentary headache intensity using EMA in tension-type headache (TTH). Forty patients with TTH wore watch-type computers for 1 week to record momentary headache intensity and also rated their headache intensities by recall. We calculated intraclass correlation coefficients between recalled headache intensity and indices from EMA recordings in the whole study population and in two subgroups divided by variability of momentary headache intensity. The results showed that consistency and agreement of momentary and recalled headache intensity were low, and this was especially marked in the subjects whose headache varied widely. These observations suggested that variability of headache intensity may affect recall of headache intensity and this should be taken into consideration in both clinical and research settings.
对头痛强度的回顾性评估常常受到多种因素的影响。最近，已开发出计算机化的生态瞬时评估（EMA）来避免诸如回忆偏倚等问题。在此，我们在紧张型头痛（TTH）患者中使用EMA比较了回顾性头痛强度和瞬时头痛强度。40例TTH患者佩戴手表式计算机1周，以记录瞬时头痛强度，并通过回忆对其头痛强度进行评分。我们计算了整个研究人群以及根据瞬时头痛强度变异性划分的两个亚组中回顾性头痛强度与EMA记录指标之间的组内相关系数。结果显示，瞬时和回顾性头痛强度的一致性和一致性较低，在头痛变化较大的受试者中尤为明显。这些观察结果表明，头痛强度的变异性可能会影响对头痛强度的回忆，在临床和研究环境中均应考虑到这一点。
