Abstract

The validity of the Minnesota Multiphasic Personality Inventory (MMPI-2) clinical scales in differentiating schizophrenia and bipolar-manic disorders was evaluated in terms of MMPI-2 congruence with psychiatric hospital treatment team diagnoses. From a pool of 286 MMPI-2 profiles, valid profiles were obtained on 5 schizophrenia (paranoid type) inpatients and 5 bipolar-manic disordered psychiatric inpatients and were assessed by using each of four MMPI profile classification methods. Overall, the rate of agreement between treatment team diagnosis and the MMPI profile classification methods for both the schizophrenia (paranoid type) and bipolar-manic disordered groups was inconclusive. The results suggest that the MMPI-2 is of limited value in differentiating inpatients with schizophrenia (paranoid type) and bipolar-manic disorders.
