Two experiments used the McGill Pain Questionnaire (MPQ) to examine the affective dimension of pain in patients whose pain was secondary to malignancy. In experiment I, segregating groups of cancer patients on the basis of extreme scores (high versus low) on the MPQ failed to produce segregation on independent measures of affect and infirmity. This outcome contrasts with earlier work with chronic benign pain patients. Experiment II compared cancer pain patients matched with benign pain patients on intensity of pain report on the affective dimension of the MPQ. Cancer pain patients reported a reliably higher affective loading to their pain. These data suggest that cancer pain patients employ different criteria than benign pain patients in selecting affective pain descriptors. Possible explanations for this difference are discussed.
两项实验使用麦吉尔疼痛问卷（MPQ）来研究继发于恶性肿瘤的患者疼痛的情感维度。在实验I中，根据MPQ的极端分数（高分组与低分组）将癌症患者分组，结果未能在情感和虚弱程度的独立测量指标上产生分组差异。这一结果与早期针对慢性良性疼痛患者的研究结果形成对比。实验II比较了在MPQ情感维度上疼痛报告强度相匹配的癌症疼痛患者和良性疼痛患者。癌症疼痛患者报告称其疼痛的情感负荷确实更高。这些数据表明，癌症疼痛患者在选择情感性疼痛描述词时采用的标准与良性疼痛患者不同。文中讨论了造成这种差异的可能原因。
