Changes in MMPI profile levels of chronic low back pain patients following successful treatment.

The present study evaluated changes in the Minnesota Multiphasic Personality Inventory (MMPI) profile levels of chronic low back pain (CLBP) patients following successful treatment for their disability. A total of 69 patients were evaluated at admission and 6 months after completing the treatment program. Results demonstrated significant decreases of the Hysteria, Depression, and Hypochondriasis scales toward normal ranges at the 6-month evaluation. These results indicate that MMPI profile levels of CLBP patients are significantly reduced to normal ranges following successful treatment.
