The MMPI as a predictor of response to conservative treatment for low back pain.
Studies that used the MMPI to predict the response of chronic low back pain patients to standard medical treatment have not produced definitive results. Patients seen in a university hospital orthopedic back pain clinic were given the MMPI before treatment, and 6 to 12 months later 76 patients completed follow-up forms that indicated their level of intensity during the previous week and their ratings of the success of treatment in relieving their pain as well as in enabling them to return to normal activities. Predictions of poor response were made in terms of either single MMPI scales or code types. Patients with poor outcome on two of the three criteria (level of pain intensity and ability to return to normal activities) had significantly higher scores on the Hs scale. The predicted high risk code types very accurately identified patients with poor response on the same two criteria; however, the code-type procedure overpredicted poor response in the good outcome group.
