Key result
MMPI-168 factor scores showed no clear advantage over clinical scale scores in correlating with mental status examination findings or predicting clinical diagnosis.
Observational
MMPI-168 factor scores do not offer a clear advantage over clinical scale scores in predicting mental status or clinical diagnosis.
No advantage for factor scores over clinical scales in diagnosis; leaves open whether refined metrics improve validity in psychiatric samples.
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.

Hedlund et al. (1977) conducted an observational in Mental health conditions. MMPI-168 factor scores vs. MMPI-168 estimated clinical scale scores and MMPI full scale clinical scores was evaluated on Correlation with mental status factor scores and discriminant analysis hit rates for clinical diagnosis. MMPI-168 factor scores showed no clear advantage over clinical scale scores in correlating with mental status examination findings or predicting clinical diagnosis.
