The problem investigated was whether a better system of K weighting could be developed for the 10 MMPI clinical scales to enhance their usefulness as measures of adjustment level within a grossly normal college population. 2-group discriminant analysis was used to determine the K value for each scale to maximize discrimination between maladjusted and adjusted college Ss, the sexes being considered separately. The revised weighting system differed greatly from the standard system; major differences were in negative weighting of Hy and deletion of weights from Hs, Pd, and Ma. Lesser changes in Pt and Sc weights were obtained, and D, Mf, Pa, and Si continued to be unweighted. Cross-validation of revised weights was shown for maladjusted college Ss and seriously maladjusted psychopathic hospital cases. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
