用于监测疼痛的电子数据收集在临床研究中变得越来越流行。过去的研究表明，电子日记提高了接收数据的及时性，有助于更高的依从率，并且患者比纸质日记更喜欢电子日记，这项研究表明，在报告时捕获当前疼痛的电子日记比回忆的疼痛评级更可靠。本研究比较了电子视觉模拟量表（VAS）上的瞬时疼痛强度评分与0至10分量表上的每周回忆疼痛评分的差异。我们要求21名慢性腰痛患者通过使用掌上电脑使用VAS每天至少一次监测其当前疼痛，持续1年。他们还每周打一次电话，并要求他们对回忆起的每周疼痛进行口头评分，评分范围从0到10。患者平均以电子方式输入数据357次，平均每周7.8次。我们发现：（1）每周回忆的疼痛与平均瞬时疼痛评估高度一致（r > .90），（2）电子监测的频率和瞬时疼痛评级的变异性（高标准差）均未对瞬时和回忆的疼痛之间的一致程度做出贡献，（3）与数字疼痛评级相比，在VAS疼痛评级中观察到天花板效应。这些研究结果表明，在许多人中，每周回忆的疼痛可能是一样有用的瞬间通过电子数据entry.Perspective收集的数据：有些人认为，记住的疼痛是有问题的，因为回忆偏见和数据，从频繁的瞬间疼痛评级与电子日记更有效。这项研究表明，回忆的疼痛对许多患者来说是有效的。(C)2005年由美国疼痛协会（C）2006年由美国疼痛协会。
Electronic data collection for monitoring pain has become increasingly popular in clinical research. Past research has shown that electronic diaries improve the timeliness of receipt of data, contribute to higher rates of compliance, and are preferred by patients over paper diaries, and this research suggests that electronic diaries that capture current pain at the moment of reporting result in more reliable ratings than recalled pain ratings. This study compared differences of momentary pain intensity ratings on an electronic visual analog scale (VAS) with weekly recalled pain on a 0 to 10 scale. We asked 21 patients with chronic low back pain to monitor their current pain at least once a day by using a VAS for up to 1 year with a palmtop computer. They were also called once a week and asked to rate their recalled weekly pain orally on a numeric scale from 0 to 10. Patients entered data electronically on average 357 times, for an average of 7.8 times a week. We found that (1) weekly recalled pain agreed highly (r > .90) with averaged momentary pain assessments, (2) neither frequency of electronic monitoring nor variability in momentary pain ratings (high standard deviations) contributed to degree of agreement between momentary and recalled pain, and (3) a ceiling effect was observed in VAS pain ratings as compared with numeric pain ratings. These findings suggest that, among many individuals, weekly recalled pain might be just as useful as momentary data collected through electronic data entry.Perspective: Some believe that remembered pain is problematic because of recall bias and that data from frequent momentary pain ratings with electronic diaries are more valid. This study demonstrates that recalled pain is as valid as momentary data for many patients. (C) 2005 by the American Pain Society (C) 2006 by the American Pain Society.
