MMPI Profiles of Brain-Damaged and Schizophrenic Patients

Abstract

Since perceptual, motor, and conceptual tests for brain-damage generally seem unable to differentiate organic from schizophrenic NP patients, an attempt was made to determine whether measures taken from a personality test might prove so capable. Accordingly the MMPI profiles of 50 organics with evidence of cerebral lesions were compared to those of 50 schizophrenics. Significant between-diagnosis effects appeared on six scales and four rules were developed from the data. In cross-validational studies, the signs proved to be useful in differentiating brain-damaged from schizophrenic males but seemed to be of no value with female Ss.
