Item analysis of cancer patient responses to the Multidimensional Affect and Pain Survey demonstrates high inter-item consistency and discriminability and determines the content of a short form.

UNLABELLED: To construct a short form (SMAPS-CP), item analysis was used to select 30 items, 1 from each of the 30 subclusters in the 101-item Multidimensional Affect and Pain Survey (101-MAPS). Representation of each of the subclusters ensured that the structure of the MAPS dendrogram obtained by cluster analysis was maintained in SMAPS-CP. Responses of outpatients with cancer to the 101-MAPS were treated by item analysis to obtain measures of interitem consistency (criterion between .40 and .80) and discriminability (criterion above .35) for each of the 101-MAPS questions. Both of these criteria for acceptance were met by 53 of the 57 questions in Supercluster I, Somatosensory Pain, by 25 of the 26 questions in Supercluster II, Emotional Pain, and by all 18 of the questions in Supercluster III, Well-being. The item within each cluster that best met the item analysis criteria was selected for the 30-item SMAPS-CP questionnaire. PERSPECTIVE: Item analysis of responses by cancer patients to a 101-item questionnaire was used to develop a short questionnaire that can be used to identify and treat both physical and emotional levels of pain without the burden of a long questionnaire.

Coping strategies of HIV patients with peripheral neuropathy.

The aim of this study was to evaluate the association between coping strategies and reports of with pain and distress in patients with HIV-related peripheral neuropathy. Seventy-eight HIV seropositive subjects completed the Coping Strategies Questionnaire (CSQ), a self-report measure that assesses seven factors, the Brief Pain Inventory (BPI), the Brief Symptom Inventory (BSI) and the Beck Depression Inventory (BDI). Bivariate correlations revealed that younger patients used more Praying-Hoping (r=-.23, p<.04) and Catastrophizing (r=-.30, p<.007). t-tests demonstrated that women used more Praying-Hoping (t(76) = 3.42, p<.01), while Hispanic and African American patients used more Praying-Hoping more than Caucasians (F (1,77) = 22.11, p=.0005). Catastrophizing significantly predicted higher scores on the BDI (t=2.968, p=.004), the Global Severity Index (GSI) of the Brief Symptom Inventory BSI (t=2.400, p=.02); and pain interference on the Brief Pain Inventory BPI (t=2.996, p=.004) controlling for age, gender, and ethnic background. These results demonstrate that coping strategies may differ according to age, gender, and ethnic background in an HIV population, and that Catastrophizing predicts distress and interference with functioning in this sample.

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. To confirm the structure of the dendrogram and hence, MAPS, factor analysis was applied to the responses by 100 outpatients diagnosed with early stage cancer. Principal components analysis of responses to the MAPS yielded six factors. In accordance with the hypothesis, 13 of the 17 clusters within the MAPS somatosensory pain supercluster loaded on three sensory factors: factor 1, severe sensory pain; factor 3, moderate sensory pain; and factor 6, numb/cold. Five of the eight clusters within the emotional pain supercluster loaded on factor 2, negative emotions. Four of the five clusters in the well-being supercluster loaded on factor 4, good health. Factor 5, manageable illness was loaded on by clusters from the well-being supercluster and the somatosensory pain supercluster. The homogeneity of the six factors found demonstrate the validity of the MAPS and the cluster structure of the dendrogram. MAPS proved sensitive to sex differences; women endorsed the negative emotions factor more strongly than did men. The MAPS factors were much more homogeneous than those reported in the literature for the McGill Pain Questionnaire.
