Validation of the Multidimensional Affect and Pain Survey (MAPS).

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.

What do ratings on unidimensional pain and emotion scales really mean? A Multidimensional Affect and Pain Survey (MAPS) analysis of cancer patient responses.

The purpose of the study was to determine what dimensions of pain predicted scores on numerical rating scales (NRSs) of Pain, Anxiety, Depression, and Health Expectation in cancer patients. Seventy-one patients with intra-abdominal cancer responded to the Multidimensional Affect and Pain Survey (MAPS) and rated their pain and emotion on the NRSs. Scores on the Pain NRS were predicted by 41% of clusters in the MAPS Somatosensory Pain Supercluster, but by 100% of clusters in the Emotional Pain Supercluster, and negatively by 51% of clusters in the Well-Being Supercluster.

Factor analysis validates the cluster structure of the dendrogram underlying the Multidimensional Affect and Pain Survey (MAPS) and challenges the a priori classification of the descriptors in the McGill Pain Questionnaire (MPQ).

The purpose of this study was to validate the content and structure of the Multidimensional Affect and Pain Survey (MAPS) by means of factor analysis. 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.

A case of human orf contracted from a deer.

Orf, or contagious ecthyma, is a rare viral dermatosis caused by a member of the genus Parapoxvirus. The typical lesion consists of solitary or multiple papules that progress through a series of stages, terminating in complete resolution. This zoonotic disease is most commonly transmitted to humans from infected sheep or goats.

Pain sensitivity in silent myocardial ischemia.

Although the cause of silent myocardial ischemia (SMI) is unknown, several theories have been advanced to explain the disorder. Most prominent among these are the suggestions that attribute the condition to generalized impaired pain sensitivity and/or enhanced endorphin activity. The present study examined both hypotheses.

Are runners stoical? An examination of pain sensitivity in habitual runners and normally active controls.

Anecdotal and clinical reports suggest that athletes are stoical. However, there are few studies comparing persons who exercise regularly with those who do not. This study compared two independent samples of regular runners and normally active controls, both without recent exercise, on cold pressor, cutaneous heat, and tourniquet ischemic pain tests.
