MMPI Scale 9 changes in incarcerated felons.

This article focuses on the scores of incarcerated male felons on the MMPI clinical subscales 4 and 9 because they are the most frequently elevated for this type of population. Over time, while scores on Scale 4 remained consistent, those on Scale 9 declined significantly. That inmates might become depressed, as a result of the foibles of incarceration, is discussed.

MMPI codetypes characteristic of DSM-III schizophrenics, depressives, and bipolars.

The association between various MMPI codetypes and DSM-III schizophrenics, depressives, and bipolars (manic or depressed) (N = 169) was examined. Most codetypes predictive of bipolar-depressed also predicted major depression, yet these codetypes were not characteristic of bipolar-manic. Furthermore, "affective" codetypes often overlapped with a diagnosis of schizophrenia.

"Floating" MMPI profiles revisited.

Attempted to replicate and update the characteristics of a sample of hospitalized psychiatric patients who produced "floating" MMPI profiles (N = 69). While the demographic data were somewhat different, the historical information, types of psychopathology and symptoms observed, and response to treatment were markedly similar. If diagnosed using DSM-III, approximately 30% of the patients would be classified as borderline character disorder, while another 20% would be classified as major depressive disorder.
