Abstract

MMPI profiles of 40 neurotic and 60 psychotic admitted patients were compared in order to evaluate the discriminating power of the test among normals, neurotics and psychotics (mostly schizophrenics). The results revealed that 1) among neurotics, the so-called neurotic triad (Hs, D, Hy) is conspicuously elevated than other factors, 2) among psychotics, the so-called psychotic tetrad (Pa, Pt, Sc, and Ma) is elevated conspicuously and more than the neurotic triad which is also elevated above the normal range. The pyramid shape of the validity profile in the psychotic group is also noteworthy when compared with that of both normal and neurotic group. However, the relatively slight difference in the degree of profile elevation between normals and neurotics or psychotics may need further considerations for factors concerned.
