The Relationship between the Psychopathy Checklist–Revised and the MMPI–2: A Pilot Study

The goal of the study was to investigate the relationship between Hare's four-facet model of psychopathy and the Minnesota Multiphasic Personality Inventory-2 (MMPI–2) in a forensic, culturally homogenous sample. 22 male prisoners from Bergen Prison participated. There was only a statistically significant negative zero-order correlation between the total PCL–R score and the score on the Depression scale of the MMPI–2. However, the results revealed that the four facets had different underlying correlates with negative affectivity. Overall, Facets 1 and 2 showed a tendency toward a negative relationship with the clinical scales on the MMPI–2, while Facets 3 and 4 had a positive relationship. Interestingly, partial correlations showed that Facet 4 of PCL–R was the only facet that correlated statistically significantly with the scores on the Psychopathic Deviate scale of the MMPI–2.

Personality Characteristics of Adult Hemophiliacs

The psychological characteristics of 36 adult hemophiliacs, mean age 29.1 years, were analyzed by means of the Minnesota Multiphasic Personality Inventory (MMPI).The MMPI profile patterns were compared between various groups of the hemophiliac sample. By the clinical criterion used in our clinic, the sample was divided into severe and mild-moderate groups. The mild-moderate group appeared to be mildly anxious-hysterical, frightened, and health preoccupied with a profile of '317-2 9 5684 0/. The severe group appeared to be more estranged and alienated than the mild-moderate group, and has a significantly higher psychopathic deviate scale (P<.01). The mean profile of the severe group was '458 23-9167 0/.The most striking differences were found in comparing subgroups of high (N=9) vs low bleeders (N=9) within the group of severe hemophiliacs with factor levels of 3% or less. The high bleeders (>243 units/lb/year, mean Factor VIII level 1.6%) were much more disturbed, had all mean clinical scales above 60 (8'25137496-0/) and significantly higher scores for Depression, Psychasthenia, and Schizophrenia (P <.05). The low bleeders (< 243 units/lb/year, mean Factor VIII level 1.8%) had no mean scale scores above 60 ('34519687 2/0).The results indicated a clear difference in the psychological adjustment of the high and low bleeders to their illness. The high bleeders had a marked increase in self negativity i.e. a sense of being defective, of hopelessness and of pessimism. Surprisingly, the low bleeders has adjusted auite well to their serious vulnerability.

Psychology of Scientist: XXXIV. MMPI Characteristics of Physical and Social Science Students: Replication and Reanalysis

In the original study, using freshmen data, 291 male college graduates in physics, zoology, sociology, and history were used to test four hypotheses derived from other MMPI studies of science students. Only one of the four hypotheses was supported: physics and zoology students were higher on Social Introversion than sociology and history students. For this replication, a second sample of 326 male graduates was obtained in the same majors and the data were reanalyzed to compare the four majors and the two time periods on each dependent variable. This time two of the four hypotheses were supported: the physics and zoology majors are higher on Social Introversion ( p < .001) and lower on Psychopathic deviate scale ( p < .001) than the sociology and history majors. Also, the physics and zoology majors are considerably higher on aptitude and achievement data than the sociology and history majors. The findings with the MMPI have small but favorable implications for the Roe and the Holland theories of career development.

The Influence of the Wives on the Treatment Outcome of Alcoholics:

The literature on the role of the wife of the alcoholic in his illness and its management has been critically reviewed by Bailey (1961). She points out that research findings are contradictory and that a unitary view of the wife's role is unwarranted. Kogan and Jackson (1964) have demonstrated within-group differences among alcoholics' wives with regard to their perception of their husbands' illness, and have suggested that such differences may have important prognostic implications. Rae and Forbes (1966) have offered a psychometric dichotomy based on the M.M.P.I. which appeared to distinguish a group of wives whose attitudes to their husbands' illness were supportive and realistic, in contrast to a group whose attitudes appeared to be the reverse. These latter wives were characterized by the M.M.P.I. as having the Psychopathic Deviate scale as a prominent feature of their personality profile. There have been no follow-up studies to assess the influence of the wife on her husband's response to treatment, and the present research attempts to assess this and to relate clinical variables to the psychometric characteristics of the marital partners.
