Diagnosis of Organic and Functional Pain Patients with the MMPI
There are contradictory findings regarding the use of the MMPI to discriminate between patients with organic and functional pain. The MMPI was administered to patients, 43 with organic and 39 with functional pain, at a university hospital pain clinic. Multivariate analyses were nonsignificant, strongly suggesting that the clinical usefulness of this scale to differentiate between patients with organic and functional pain is highly questionable.
