Correlates of broad MMPI categories.

Investigated behavioral correlates of MMPI profiles of 363 male psychiatric Ss, classified by the Goldberg system and by two systems based on Welsh's factor scales A and R. For each profile category, frequency of occurrence for 81 behavioral descriptors from an adjective check-list was compared with frequency in the remaining categories. Two of the systems were compared with classification by code-type. Categories were not differentiated strongly on the basis of behavioral descriptors, although some trends were indicated. This study supports the position that interpretive systems that provide relatively few classification alternatives are of limited value in the interpretation of individual profiles. The results are discussed in terms of category heterogeneity.
