Relationships between admission variables and MMPI scale scores of hospitalized alcoholics.

286 alcoholic Ss were divided into subcategories on the basis of seven admission variables. The mean MMPI scale scores of the subcategories were compared Education, age, population of area of residence, marital status, and admission status emerged as the variables most clearly associated with differential MMPI responses. On the other hand, surprisingly few differences were associated with the number of admissions for treatment of alcoholism or religious preference.

Validation of Gilberstadt and Duker's 8–6 Profile Type on a Black Sample

The procedure employed by Gilberstadt and Duker (1965) with a Midwestern sample to determine the characteristics of the 8–6 MMPI profile type was replicated with a Southeastern black sample. The cardinal features of paranoid schizophrenia seemed remarkably similar in both groups but significant differences were found in traits, symptoms, and MMPI scale scores. In general, the Southeastern black sample showed a somewhat greater surface manifestation of pathological traits and admitted to more experiences that are viewed in the while culture as odd and bizarre. The differences were interpreted as probably reflecting different baseline personality characteristics between Southeastern blacks and Midwestern whites. The more apparently pathological symptoms and traits in the black population are interpreted as a manifestation of truly adaptive behavior for this subgroup in an aversive social environment.

Obtaining 16PF scores from the MMPI, and MMPI scores from the 16PF.

Summary Recent statistical analyses of the relation of the MMPI surface traits to the source traits in the 16 P.F. were extended to (a) the calculation of beta weights for estimating MMPI scale scores from the 16 P.F. and (b) deriving the MMPI item composition in terms of 16 P.F. scores from the MMPI, and vice versa. It has been argued from the specific nature of surface and source traits that additional diagnostic insight can be gained from their comparison, a principle which has been designated as depth psychometry.

Personality test configurations in acne vulgaris.

52 college girls (mean age 20 yr.) were clinically divided into groups according to the severity of their acne. They were then given a battery of tests, of which the MMPI was found to be the most sensitive. Ss then applied a three-step cosmetic preparation once daily to their faces and the same battery of psychological tests was given subsequent to 3 and 6 mo. of treatment. It was found that MMPI scale score differences reached minimal to fairly high levels of significance between acne and nonacne Ss and between mild and severe acne sample groups. In the mild-acne group the therapeutic effects of skin treatment were reflected in relevant scale score changes; severe acne Ss became more defensive and somewhat conventionalized in their test responses.

Changes in MMPI scale scores and an index of psychopathology following unilateral temporal lobectomy for epilepsy.

SUMMARYThe direction and extent of change in personality functioning, as measured by the Minnesota Multiphasic Personality Inventory (MMPI), were investigated longitudinally before and one year or more following unilateral temporal lobectomy for intractable psychomotor seizures. Although the pre‐ to postoperative changes were not sufficiently profound to postulate a major reorganization of personality functioning in these patients, selected scale scores consistently were observed to decline in the less psychopathological direction, especially on test measures for which schizoadaptive behavioral correlates have been established in psychiatric populations. These reductions were not conspicuously different after left as compared to right temporal lobectomy. However, the presence of bilateral preoperative EEG abnormalities was associated with higher initial MMPI scale elevations and greater scale score declines postoperatively. This was especially prevalent among patients with independent bitemporal EEG spike foci preoperatively.RÉASUMÉALa direction et l'eAtendue des changements de la personnaliteA, aG l'aide de l'Inventaire de PersonnaliteA Multiphasique Minnesota (MMPI), ont ete explorees longitudinale‐ment avant et un an ou davantage apreGs lobotomie temporale unilateArale pour crises psychomotrices rebelles.

COMPARISON OF COMPUTER-DERIVED PERSONALITY PROFILE AND PROJECTIVE PSYCHOLOGICAL TEST FINDINGS.

A computer program of MMPI interpretations originally developed for general practitioners working in a clinic setting was modified to some extent for use with a psychiatric inpatient population. This particular program, designed for a 1401 computer, is composed of 60 statements referring to specific MMPI scales, and a number of "modifier" statements combining information from two or more scales in configural fashion. Each of the statements referring to one particular scale reflects a low, normal, mild, moderate or marked "degree of elevation" of that scale. The computer program prints the MMPI profile as well as the interpretive statements. The computer interpretive statements were contrasted with findings from batteries of projective tests administered to the same patients. The psychologists administering and interpreting the projective instruments rated each of the computer statements appearing in a patient's MMPI record on a 6-point agreement-disagreement continuum. The psychologists judged the computer interpretations to be consistent with their projective test findings a far greater number of times than would be expected by chance. The highest agreement was with computer interpretations derived from the L and Hy scales, while the lowest occurred in reference to the Pd and Pt scales. The library of computer statements was noted to be most compatible with impressions from projective tests when describing the meaning of more elevated MMPI scores. Disagreement was most prevalent in the interpretive categories attempting to cover the low and normal degrees of elevation of MMPI scale scores. Diagnosis did not appear to enter into the amount of agreement obtained. Within the group of 5 psychologist-raters participating in the study, the least experienced tended to agree most with the computer statements. In general these results indicate that computer interpretations of MMPI records yield meaningful psychological information about psychiatric patients, with an economy of professional time, and a sharp reduction in cost.

NOTE OF CAUTION ON THE FACTOR ANALYSIS OF THE MMPI.

Abstract : Although the dangers associated with factoring test scales containing overlapping items (items used on more than 1 scale) have been pointed out by Guilford (1952), factor studies of scales embodying item overlap continue. The present study explores the possibility that the neurotic triad and the psychotic triad or tetrad factors found in 4 studies derive from the existence of a methodological artifact associated with item overlap. To test this possibility, MMPI interscale common-element correlations (Produced solely by item overlap) were factor analyzed. 2 or 3 factors extracted are highly similar to neurotic triad and psychotic triad or tetrad factors found for 4 samples. These 2 factors do not appear in a factor analysis of truncated (overlap items removed) MMPI scale scores. Since the overlap factors are based solely on the scale intercorrelations due to overlap items, these results appear to support Guilford's warning and open to question the legitimacy of these MMPI factors.

AROUSAL SEEKING AS A MOTIVATION FOR VOLUNTEERING: MMPI SCORES AND CENTRAL-NERVOUS-SYSTEM-STIMULANT USE AS SUGGESTIVE OF A TRAIT.

Abstract Subjects who indicated that they would volunteer for a psychological experiment reported significantly moTe coffee and caffeine-pill usage than nonvolunteers. Male volunteers more frequently reported cigarette smoking. In this study, males and females each scored significantly higher on the following MMPI scales: paranoia, schizophrenia, hypomania, cigarette smoking, control and social-participation scales. Male volunteers scored significantly higher on the masculinity-femininity and dominance scales, while the male nonvolunteers scored higher on the quantitative orientation scale and the social introversion scale. Female volunteers scored significantly higher on the psychopathic deviate, psychasthenia, F, and manifest-hostility scales; and significantly lower on the lie, defensiveness, and responsibility scales. The results suggest that a personality trait of arousal seeking could explain some of the MMPI scale score differences as well as the central-nervous-system-stimulant usage. The results ...

Relationship of College Attendance to Personality Characteristics and Earlier Delinquent Behavior

Follow-Up studies of 4,000 children tested with the MMPI in the ninth grade indicate that severity of delinquency and frequency in its occurrence are notably less among those who went on to college; that there is a marked difference in means and variances of the MMPI scales between the college group and those who dropped out of school or did not go on to college; and that the mean MMPI scale scores that discriminate the college group from the noncontinuing group are higher, in general, for the latter.
