The purpose of this research was to empirically reexamine the diagnostic discrimination power and clinical applicability of the Sc scale of the MMPI in Korean culture. In order to improve sensitivity and practicallity of the items of the Sc scale, an attempt was made to construct a new scale on the bases of item response rate obtained from comparing criterion group with norm group. It was found that mean difference of raw score on the modified Sc scale named MSc scale which was composed of 60 items was statistically significant between normal and schizophrenia group, which should better results compared with that from the existing Sc scale. Discriminant analysis and cross validation study also proved that MSc scale is better than Sc scale in discriminating schizophrenia from normal group. These results suggest that MSc scale could be better adopted for the purpose of identifying schizophrenia group at least in the present korean culture. It is recommended that further empirical researches be done in order that the newly developed MSc scale ca be used safely in clinical settings.
