疼痛强度的自我报告评级在研究和临床实践中普遍存在。除了对当前疼痛进行评级外，患者还经常被要求提供代表几天或几周内疼痛强度的评级。很少有数据可以深入了解人们如何理解和完成这一回忆任务。这项研究描述了对 106 名患有慢性疼痛的风湿病患者进行结构化访谈的结果，了解他们如何根据过去一周的视觉模拟量表得出疼痛强度评级。大多数患者无法连贯地阐明他们是如何得出评分的。此外，患者之间也没有一致性。确定了各种不同的策略来指导他们的反应。这些结果支持了对回顾性回忆评级的意义和有效性的担忧。回忆疼痛，看似简单的任务，却是一个看似更复杂的现象。需要探索改进对回忆疼痛的测量的努力。改进教学设置、更明确地指定目标疼痛的维度、避免使用单一项目来测量疼痛、改进对预期参考组的描述、确定患者能够记住疼痛的时间长度和限制回忆期，都是需要探索的合理方法。观点：这些结果强调我们对常用疼痛回忆问题所引出的信息的含义缺乏充分的理解。他们指出了明确指定寻求何种疼痛性质以及患者在报告期间应如何总结它们的潜在重要性。 (c) 2006 年，美国疼痛协会。
Self-report ratings of pain intensity are ubiquitous in research and clinical practice. in addition to rating their current pain, patients are often asked to provide ratings to represent pain intensity over several days or weeks. Few data are available that provide insight into how people understand and accomplish this recall task. This study describes the results of structured interviews with 106 rheumatology patients with chronic pain about how they arrived at their ratings of pain intensity on a visual analog scale referenced to the past week. Most patients were unable to coherently articulate how they derived their ratings. Moreover, there was no consistency across patients. A variety of different strategies were identified that guided their responses. These results support the concern about the meaning and validity of retrospective recall ratings. Recall of pain, a seemingly simple task, is a deceptively more complex phenomenon. Efforts to improve the measurement of recalled pain need to be explored. Improving instructional sets, clearer specification of the dimensions of pain being targeted, avoiding use of a single item to measure pain, improved description of intended reference groups, and determining the length of time that patients are able to remember pain and limiting recall periods are reasonable methods that need to be explored.Perspective: These results emphasize our lack of a full understanding of the meaning of the information elicited by commonly used pain recall questions. They point to the potential importance of clearly specifying what qualities of pain are sought and how the patient should summarize them over the reporting period.
