Evaluated the diagnostic adequacy of the Mini-Mult in a psychiatric population and a presumed normal sample as well as the descriptive accuracy of statements inferred from the Mini-Mult profiles of the patient sample. The Mini-Mult showed significant correlations with the full MMPI for all scales except Hs in a male psychiatric inpatient sample and for all scales except F, Hs and D in a female nursing school applicant sample. Nevertheless, in both samples there are significant mean differences on most scales when the two techniques are compared. For the psychiatric sample in cases where both the Mini-Mult and MMPI give profiles codeable into Marks and Seeman (1963) profile types, the Mini-Mult yields only limited prediction of profile type and descriptive statements. For the student nurse applicant sample, there is good agreement (86%) between the techniques when used only to screen for possible pathology. The Mini-Mult seemed to have some promise in applications involving the screening of presumed normals, but showed little success in predicting diagnostic and descriptive features as inferred from the full MMPI.
