title: Empirically derived MMPI profiles. Coronary bypass surgery.
abstract: A cluster analysis of eight clinical scales of the MMPI-168 was performed on data from 129 subjects awaiting coronary bypass surgery. Four abnormal profiles were derived and these profiles were consistent with clinical expectancy. The five empirically derived profiles were labeled as a) normal--that is, no elevated scales; b) marginal distress--elevated Hs; c) conversion V--elevated Hs and Hy; d) neurotic--elevated Hs, D, Hy, and Pt; and e) generalized distress--elevated D, Hy, Pd, Pa, Pt, and Sc. Subsequent postsurgical follow-ups were done at 3-, 12-, and 24-month intervals. These data suggest that the profiles retained their characteristic shape and were still statistically different from each other, but the overall elevation decreased significantly after successful surgical intervention. To externally validate these profiles, the five derived groups were compared in terms of Beck Depression scores and the State/Trait Anxiety Inventory. These results were consistent with the MMPI. These data are discussed in terms of developing models for assessing the interaction of personality and specific stressors.
