D. Boone, DIFFERENTIAL VALIDITY OF THE MMPI-2 SUBTLE AND OBVIOUS SCALES WITH PSYCHIATRIC-INPATIENTS - SCALE 2, Journal of clinical psychology, 51(4), 1995, pp. 526-531
The construct and concurrent validity of the MMPI-2 Scale 2 Subtle and
Obvious scales were examined for a group of 67 psychiatric inpatients
. Validity coefficients for the Obvious scale were uniformly greater t
han those for the Full and Subtle scales. Subtle scale validity coeffi
cients were negative and attenuated the validity of the Full clinical
scale. Use of Obvious items resulted in more accurate prediction of as
sessed suicide risk, while inclusion of the Subtle items did not add a
ny useful information in the prediction of assessed suicide risk or ps
ychiatric diagnosis. It is recommended that future research that uses
the MMPI-2 basic clinical scales examine the differential validity of
the Subtle and Obvious scales.
