Comparative Validity Of MMPI-168 Factors And Clinical Scales

Abstract

This study further explores the relative merits of MMPI factor scores versus clinical scale scores, using the MMPI results of a large unselected sample of public mental health patients and using mental status examination findings and clinical, diagnosis as criterion variables. Correlation of MMPI-168 factor scores, MMPI-168 estimated clinical scale scores and MMPI full scale clinical scores with mental status factor scores failed to evidence any clear advantage for any of the three MMPI variables. Similar findings were obtained for discriminant analysis "hit" rates, using clinical diagnosis as the prediction criterion.
