Validity of the Wiener subtle and obvious scales for the MMPI: Another example of the importance of inventory-item content

Description
Summary:Conducted canonical variate analysis of MMPI scale T scores and factor scores derived from rating criteria from 2 independent patient samples containing 384 (mean age 26.3 yrs) and 400 (mean age 30.2 yrs) Ss. Results provided substantial evidence for the validity of the interpretive intent of the standard scales Depression, Hysteria, Psychopathic Deviate, Paranoia, and Hypomania (accounting for 28.5 and 25.7% of the criterion variance) and their obvious versions (30.4 and 34.9%), while providing little support (13.4 and 5.6%) for the interpretive intent of the subtle scales. Subtle scale elevation was inversely related to symptomatology on some nonrelated behavioral dimensions. Inclusion of an estimate of client defensiveness did not improve the predictive ability of the subtle scales. (8 ref)
