The MMPI-168 profiles of 120 rehabilitation medicine inpatients were clustered according to J.H. Ward's minimum-variance method, and four patient clusters were identified. The profile of mean MMPI-168 scores for the largest cluster, representing about one-half of the total sample, showed no clinical elevations on any scale. The remaining three clusters were characterized primarily by depression, somatic focusing, and personality disorganization, respectively. Discriminant analysis supported the differentiation among clusters in terms of MMPI-168 scores and suggested that ruminative worry and openness to identifying problems accounted for the majority of the differentiation. With the exception of the cluster characterized primarily by depression, the three remaining clusters seemed quite similar to profile types consistently found in research on chronic pain samples.
