| Abstract: | Developed 3 MMPI scales: (a) an unweighted scale consisting of 80 items differentially endorsed by 61 organics and 65 schizophrenics at a Veterans Administration psychiatric hospital, (b) the same items weighted as a function of their differentiating power, and (c) a short form consisting of the 30 most powerful items weighted in accordance with their differentiating strength. Scales were cross-validated in a state hospital population and a general medical and surgical Veterans Administration hospital. Results indicate that the scales differentiate male organics from schizophrenics but are of dubious value among female populations. (16 ref.)
