WHAT PATHOLOGICAL DIMENSIONS LIE BEYOND NORMAL DIMENSIONS OF 16PF - A COMPARISON OF MMPI AND 16PF FACTOR DOMAINS

A set of mutually exclusive, exhaustive parcels of MMPI items and the 16 personality factor scales from the Cattell 16 PF were factored together on 217 normal and 40 abnormal adult Air Force men. The analysis of the resulting 64 variables (45 MMPI parcels and 19 16 PF scales) yielded 21 factors, of which 13 are clearly identifiable as factors in the 16 PF and 4 are clearly MMPI factors. MMPI data were scored also for the traditional 14 clinical scales, and their predictability from 16 PF source trials examined in terms of the squared multiple correlations. The 7-factor space typically represented by the MMPI clinical scales was found to lie within the dimensionality of the Cattell 16 PF. The total prediction of the set of MMPI clinical scales from a single form (A) of the 16 PF, uncorrected for attenuation, is represented by the canonical correlation of .8. (47 ref.)
