The use of pain scales that refer to a past time period is thereby based on the assumption that patients accurately remember their 'average', 'greatest' and 'least' pain. The present study addresses the validity of numerical pain rating scales that refer to a past period of time (herein, the past 7 days). Routine data from 94 patients with chronic pain were retrospectively analysed. Pain questionnaire data on the greatest, least and average pain during the past week and on current pain were compared with the mean value of entries in a pain diary from the corresponding period. The retrospectively assessed average, greatest and least pain values were consistently slightly higher than the corresponding values of daily current pain measured for the studied collective of chronic pain patients. Current pain (at the time of answering the questionnaire) better represents daily currently measured pain [intraclass correlation (ICC)=0.885] than retrospective individual measurements. The greatest correlation with averaged diary data was shown by the combination of questionnaire data on average, least and current pain (ICC=0.911). The high correlations between the questionnaire and diary data support the validity of retrospective pain surveys. However, the current status influences recall. Thus, composite retrospective pain data improve with the addition of current pain.
因此，使用涉及过去时间段的疼痛量表是基于患者能够准确记住其“平均”、“最剧烈”和“最轻”疼痛的假设。本研究探讨了涉及过去时间段（此处指过去7天）的数字疼痛评分量表的有效性。对94例慢性疼痛患者的常规数据进行了回顾性分析。将过去一周内最剧烈、最轻和平均疼痛以及当前疼痛的疼痛问卷调查数据与相应时间段疼痛日记中的记录平均值进行比较。回顾性评估的平均、最剧烈和最轻疼痛值始终略高于为该慢性疼痛患者群体测量的每日当前疼痛的相应值。当前疼痛（在回答问卷时）比回顾性个体测量更能代表每日当前测量的疼痛[组内相关系数（ICC）=0.885]。平均、最轻和当前疼痛的问卷调查数据相结合与日记数据的平均相关性最高（ICC=0.911）。问卷调查和日记数据之间的高相关性支持了回顾性疼痛调查的有效性。然而，当前状态会影响回忆。因此，加入当前疼痛后，综合回顾性疼痛数据会有所改善。
