Two separate studies were carried out to determine if three visual analogue scales for various feelings including pain could be marked consistently by patients, without reference to previously completed scales. Sixty patients undergoing extraction of their lower third molars had measurements of acute preoperative anxiety, expected postoperative pain and postoperative perceived pain three times in quick succession. There was no significant difference between the three measurements for any of the feelings. Although a correlation was detected between expected pain and preoperative anxiety, there was no meaningful relationship between perceived postoperative pain and expected pain or preoperative anxiety. Eighty patients suffering from a wide range of chronic painful states completed three identical scales for pain, anxiety, depression and mood during their first visit. These measurements were repeated at a later time following a treatment, with the addition of a visual analogue scale for pain relief. Mean scores for anxiety, mood and pain relief were consistent, but mean pain scores were more variable. There was a very close correlation between any two feelings expressed on these visual analogue scales during both the initial and second visits. Litigation or social problems were not associated with increased pain scores.
开展了两项独立研究，以确定包括疼痛在内的各种感受的三种视觉模拟量表是否能由患者在不参考先前已完成量表的情况下进行一致的标记。60名接受下颌第三磨牙拔除术的患者连续三次快速测量术前急性焦虑、预期术后疼痛和术后感知疼痛。对于任何一种感受，三次测量之间均无显著差异。虽然检测到预期疼痛与术前焦虑之间存在相关性，但术后感知疼痛与预期疼痛或术前焦虑之间没有有意义的关系。80名患有各种慢性疼痛状态的患者在首次就诊时完成了关于疼痛、焦虑、抑郁和情绪的三种相同量表。在治疗后的晚些时候重复这些测量，并增加了一个疼痛缓解视觉模拟量表。焦虑、情绪和疼痛缓解的平均得分是一致的，但平均疼痛得分更具变异性。在初次就诊和第二次就诊期间，这些视觉模拟量表上表达的任意两种感受之间都存在非常密切的相关性。诉讼或社会问题与疼痛得分增加无关。
