Abstract
The Millon Behavioral Health Inventory was administered to 67 individuals with chronic low back pain who participated in a rehabilitation program on pain and stress. Base-rate scores from the 20 scales, submitted to cluster analysis using Ward's minimum variance method, gave four subtypes. Discriminant analysis accurately classified 98.51% of the sample. The discriminant functions were interpreted and labeled as I: somatic distress and II: inhibition-dependency. The groups were then examined for differences and similarities with respect to those dimensions, and the groups were labeled I–introversive, II–denial/minimizers, III–conformers, and IV–severe psychophysiological reaction. The types were next compared across medical, vocational, and demographic data. With the exception of sex of subject, no other data were significant by type. The results were discussed, and recommendations for research were made.
