The McGill Pain Questionnaire is in widespread use as a means of understanding the pain patient and monitoring treatment response. The current study consists of a replication of the construction of the questionnaire through the use of maximally dissimilar methodology and statistical techniques. The study comprised two stages: (a) an attempt to replicate the grouping of words within the questionnaire; and (b) an investigation of the intensity relationships of words within each subgroup. A direct grouping technique was used for stage (a), whereby 90 subjects sorted the words into semantically similar groups. A similarity matrix was constructed in terms of the number of times each word was associated with each of the other 78 words and subjected to cluster analysis. Inspection of the 20-group solution revealed considerable similarity with the original questionnaire. The intensity relationships were examined by asking a further group of 20 subjects to rate words on analogue scales. The results suggest a unidimensional solution to be inappropriate for a proportion of the subgroups. While there was a close resemblance with the MPQ, there was evidence for reducing the number of subgroups, as a 16-group solution offered a sensible and statistically parsimonious amalgamation. The implications of this work for the use of questionnaire methods are discussed.
麦吉尔疼痛问卷被广泛用作了解疼痛患者和监测治疗反应的一种手段。当前的研究包括通过使用极为不同的方法和统计技术来复制该问卷的构建过程。该研究包括两个阶段：(a) 尝试复制问卷中的词汇分组；(b) 调查每个子组内词汇的强度关系。对于阶段 (a)，使用了直接分组技术，即90名受试者将词汇分类到语义相似的组中。根据每个词与其他78个词中每个词关联的次数构建相似性矩阵，并进行聚类分析。对20组的结果检查显示与原始问卷有相当大的相似性。通过要求另一组20名受试者在模拟量表上对词汇进行评分来检查强度关系。结果表明，对于一部分子组而言，一维解决方案并不合适。虽然与MPQ有密切的相似性，但有证据表明可以减少子组数量，因为16组的解决方案提供了合理且统计上简约的合并方式。讨论了这项工作对问卷方法使用的影响。
