Pain-related correlates of MMPI profile subgroups among back pain patients.

96 17–80 yr old male and 218 16–83 yr old female outpatients at a back pain clinic were administered the Cornell Medical Index, the Minnesota Multiphasic Personality Inventory (MMPI), the McGill Pain Assessment Questionnaire—Revised, and the Shipley Institute of Living Scale. Analysis showed greater disruption of daily activities and affective disturbance and poorer adjustment to pain among subgroups with elevated neurotic scales. Results are consistent with those of similar studies of chronic pain patients showing that MMPI profile subgroups may be identified that are associated with relatively unique pain-related correlates.
