Accuracy of MMPI Decision Rules in Establishing DSM III Diagnoses
The usefulness of MMPI decision rules in identifying corresponding DSM III diagnosis was explored. A study of 118 outpatient evaluations yielded a low degree of accuracy for both the Meehl-Dahlstrom and Henrichs decision rules. Given those results, a discriminant analysis was performed for three DSM III diagnostic categories (schizophrenic disorders, affective disorders, and no mental disorders); this analysis suggested potential usefulness for multivariate-based MMPI decision rules.
