Demographic and prognostic characteristics of psychiatric patients classified by gross MMPI measures.

William G. Klett

Norris D. Vestre²

Abstract: Application of the Gilberstadt-Duker MMPI rules to the MMPI profiles of patients admitted to a psychiatric hospital revealed that only 28% of the patients produced classifiable profiles. A large proportion (36%) of the patients produced invalid profiles. These patients were studied further by classifying all profiles on the basis of gross indices of valid (i.e., L > 60 and/or F > 80) vs. invalid and normal (i.e., all clinical scales less than T = 70) vs. abnormal. Demographic, diagnostic, and prognostic differ… Show more

Mmpi characteristics and correlates among adolescent psychiatric inpatients

1979

Investigated the salient response characteristics and clinical correlates of the Minnesota Multiphasic Personality Inventory (MMPI) in an adolescent psychiatric inpatient population (N = 64). MMPI data were analyzed by both univariate and multivariate statistical techniques. Results revealed that the MMPI profiles of male and female adolescents were highly similar, and few significant relationships were found between MMPI based diagnostic groupings and selected demographic and symptomatological patient features. MMPI scale data, particularly validity scale scores, were found to be of significant utility in accurately classifying adolescents' length of hospitalization. Further, results of principal components analyses generated three factors, labelled General Psychopathology, Defensiveness, and Sociopathy, which accounted for a major proportion of MMPI scale score variance. Findings were discussed in terms of implications for current research and clinical practices and areas for future investigation.

The effects of system combination and rule relaxation on classification rates in the Marks and Seeman and Gilberstadt and Duker systems of MMPI profile analysis were studied in a sample of 541 inpatients. The initial separate system classification rate of approximately 27% was increased first to 49% by joint application of both systems of analysis, and then to 74% by relaxation of 1 rule per profile type. Classification rates for each of the 35 profile types were also reported.

profiles of 363 in-patient and out-patient urban psychiatric patients were studied. The profiles as a group did not differ markedly from two recent American samples in their single most elevated clinical scales, most commonly occurring twopoint code types, or classifiability according to the profile typology of Marks and Seeman (1963). With no rule violations, the Marks and Seeman typology classified only 20 per cent of the sample; allowing one rule violation per profile increased the classification rate to only 41 per cent. Further research into the applicability of American MMPI clinical lore to English-speaking Canadian populations was encouraged. * This report is based on a paper read before the Ontario Psychological Association, Toronto, 1973. The authors would like to thank John Goodman for providing access to the data and Freda Wilson for assistance with data collection.
