title: Use of the MMPI and MCMI in predicting outcome of lumbar laminectomy.
abstract: This study compared the abilities of the MMPI and Millon Clinical Multiaxial Inventory (MCMI), using discriminant analyses, to predict outcome after lumbar laminectomy for chronic back pain. Sixty-nine males and 60 females with lumbar discogenic disease completed MMPIs and MCMIs before surgery and were classified as either having good or fair/poor surgical outcomes based on self-reported pain relief, return to work, restriction of activities, and medication use. Results showed both the MMPI and MCMI to have moderate ability to predict surgery outcome. A slightly higher classification hit rate was obtained with both instruments when age, sex, employment status, and presence of compensation/litigation issues also were entered into the prediction equation. Results indicate the need for caution in using either instrument to make predictions of surgery outcome in individual cases.
