A Cluster Analytic Approach To MMPI Profile Types

Multivariate Behavioral Research
M Lorr, A Suziedelis

Abstract

Aims were to identify the profile types present in MMPI scale scores using Ward's hierarchical procedure and a nonhierarchical average linkage method. One data set consisted of the 35 code types developed by Gilberstadt-Duker and Marks-Seeman-Haller. Another data set consisted of Lanyon's group profiles of 210 diagnostic classes. These profiles were subdivided into odd-even samples of 105. Analysis of the 35 code types disclosed four clusters by either procedure: neurotics, depressed psychotics, excited psychotics, and sociopaths. Analysis of the two Lanyon subsamples uncovered several normal subgroups as well as the clusters found among the code types. These results indicate that a relatively small number of homogeneous subtypes can account for most code types and diagnostic group profiles.
