Unlabelled: The concurrent construct validity of the Multidimensional Affect and Pain Survey (MAPS) was determined in a sample of 100 oncology outpatients. As recommended by Jensen, we examined the frequency pattern of correlations between MAPS and standard questionnaires that reached a criterion level of significance. As predicted, the 17 subclusters in the MAPS Somatosensory Pain supercluster showed a higher mean frequency of criterion correlations with the 4 sensory-related groups of items from the MPQ and, equally important, a lower frequency of criterion correlations with unrelated constructs, POMS, and the MPQ Affective Class.

The 101-MAPS is based on a dendrogram obtained by cluster analysis and contains 30 clusters subsumed within three superclusters. If the MAPS is a valid questionnaire for the quantification of emotion and pain in patients, then factor analysis of patients' intensity ratings should produce factors which correspond to the cluster structure of the dendrogram.
