Abstract
A “customized” clinical typology of six types (for 10% to 30% of the sample each) was derived on 150 inpatient alcoholic veterans as part of a more comprehensive clinical research project. The types were derived on 18 variates, which included the 13 clinical and validity scales of the MMPI, 2 intellectual estimates, 2 perceptual estimates, and an employment rating, using Ward's procedure. The MMPI clinical profiles for the types matched closely known MMPI actuarial patterns, as well as those from prior alcoholism typing research. The non-MMPI variates seemed to add importantly to the clinical meaningfulness of the derived types. Type contrasts on a number of demographic and index variables were also significant and provided additional descriptive and validation data. The desirability and utility of combining several common measures as a basis for types that would be a central part of ongoing clinical programming and research are discussed.
