The correlations of symptoms of hysteria with 87 symptoms relevant for diagnosing schizophrenia were examined in a sample of 112 patients (70 women and 42 men whose mean age was 38.1 yr., SD = 9.8) with DSM-III diagnosis of schizophrenia. Hysterical symptoms were recorded in 37.5% of the schizophrenics. No significant relationships (phi coefficients) were found to key symptoms of schizophrenia.

The purpose of this study was to compare the MMPI performance of Hispanic, black, and white mental patients who were matched on the psychiatric diagnosis of schizophrenia. It was hypothesized that ethnic patient groups from a maximum security hospital would not differ significantly on any of the 13 MMPI scales as a result of being equated on psychiatric diagnosis. A secondary purpose was to examine the most frequently occurring two-point high-point codes elicited by each of the ethnic groups. Significant multivariate differences were indicated among the MMPI scales and across ethnic groups. Significant univariate differences were found among the three ethnic groups on six of the 13 MMPI scales. The most frequently occurring two-point high-point code for Hispanic and white groups was the '8-2/2-8' code, while for the black group it was the '6-8/8-6' code. Results were discussed with regard to ethnicity, psychiatric diagnosis, and MMPI performance of ethnic/racial groups.

In two samples of 150 and 310 schizophrenic patients, scores for hallucinations were significantly associated with scores on disorganization.
