疼痛量表锚点的不同使用可能会影响回忆的疼痛评级、评级一致性以及实际评级变化和疼痛缓解评级之间的一致性。这项调查检查了代表最大疼痛量表锚的事件的变化。参与者（N = 68，50% 女性）提供了 0 至 100 个疼痛等级的最大锚定事件，并通过使用自我选择的事件和研究者提供的事件来评估冷加压疼痛。然后，参与者可以更改他们自己选择的事件。然后使用修改后的事件或原始事件对第二次冷加压试验进行评级。百分之四十一的参与者改变了事件，并且新的事件更有可能涉及冷或热，但事件的疼痛程度和第二次试验的疼痛评级没有改变。根据自选事件进行评分时，冷加压疼痛评分高于研究者提供的强度事件（平均值 = 80.13，SD = 19.30；平均值 = 60.81，SD = 27.45）和不愉快程度（平均值 = 80.84，SD = 19.07；平均值 = 59.07，SD = 27.53），这可能是由于研究者提供的事件的次最大痛苦。因此，无论实际事件如何，数字量表的宽度对于最大事件都是稳定的。 观点：本报告确定了参与者用来表示最大疼痛量表锚点的身体事件的变化，并表明事件疼痛的最大性质比实际事件的变异性更重要。我们的结论是，我们使用的数字疼痛量表是可以理解和稳定的，但我们建议，可以通过评估受访者用来概念化最大疼痛量表锚点的事件的疼痛程度来改进疼痛测量的教学集。 (c) 2007 年，美国疼痛协会。
Variable use of pain scale anchors may influence recalled pain ratings, rating consistency, and agreement between actual rating change and ratings of pain relief. This investigation examined change in events that represent maximal pain scale anchors. Participants (N = 68, 50% women) provided events for maximal anchors of 0 to 100 pain scales, and cold pressor pain was rated by using self-selected event/s and an investigator-provided event. Participants then were allowed to change their self-selected event/s. The revised event/s or original events were then used to rate a second cold pressor trial. Forty-one percent of participants changed event/s, and the new event/s was more likely to involve cold or heat, but the painfulness of events and the pain ratings of the second trial did not change. The cold pressor pain ratings were higher when rated on the basis of self-selected event/s than the investigator-provided event for intensity (mean = 80.13, SD = 19.30; mean = 60.81, SD = 27.45) and unpleasantness (mean = 80.84, SD = 19.07; mean = 59.07, SD = 27.53), which could be due to the submaximal painfulness of the investigator-provided event. Therefore, the width of numerical scales is stable with maximal events regardless of the actual events.Perspective: This report identifies change in physical events that are used by participants to represent maximal pain scale anchors and suggests that the maximal nature of the events'painfulness is more important than variability in the actual events. We conclude that the numerical pain scales we used are understandable and stable, but we suggest that instructional sets forpain measurement may be improved by evaluation of the painfulness of events thatrespondents use to conceptualize maximal pain scale anchors.
