Responses to the McGill Pain Questionnaire (MPQ) were described in two samples of arthritis patients, an inpatient group (n = 94) and an outpatient group (n = 94). Subjects in both samples used a similar set of sensory words to describe their arthritis pain. The inpatient sample, however, used affective words of higher intensity than the outpatient sample. Because the two samples came from a common population, they were combined and exploratory factor analyses using principal component analysis with first oblique and then orthogonal rotations were performed. The analysis yielded 6 factors that accounted for 58.3% of the variance in the sample. Clear sensory factors, an affective factor and an evaluative factor were identified. The study provides preliminary evidence that a substantial affective dimension underlies the MPQ responses of arthritis patients and confirms the parsimony of a 3-factor solution for the questionnaire.
在两个关节炎患者样本中描述了对麦吉尔疼痛问卷（MPQ）的反应，一个住院患者组（n = 94）和一个门诊患者组（n = 94）。两个样本中的受试者使用了一组相似的感觉词汇来描述他们的关节炎疼痛。然而，住院患者样本使用的情感词汇强度高于门诊患者样本。由于这两个样本来自同一总体，因此将它们合并，并使用主成分分析进行探索性因素分析，先进行斜交旋转，然后进行正交旋转。分析得出6个因素，占样本方差的58.3%。确定了明确的感觉因素、一个情感因素和一个评价因素。该研究提供了初步证据，表明情感维度在关节炎患者的MPQ反应中起着重要作用，并证实了该问卷三因素解决方案的简洁性。
