Are separate black and white MMPI norms needed? An IQ-controlled comparison of accused murderers.

Investigated racial differences in MMPI responding by comparing samples of black and white males charged with murder (N = 160). Mancova was used to control statistically for the effects of intelligence on racial differences. Prior to the use of Mancova blacks had significantly higher scores on F and MA. When the effects of intelligence were controlled F and MA were no longer significantly different for blacks and whites. However, with black and white SS equated on IQ, significant differences emerged on the K and SI scales. These results indicate that construction of separate black and white norms for violent offenders is premature. More research is needed on variables that affect individual differences on the MMPI.

Perceptual differentiation among drug addicts: correlations with intelligence and MMPI scores.

Examined the level of perceptual differentiation, as measured by Witkin's Embedded Figures Test, as well as the correlations between perceptual differentiation and scores on The Shipley Institute of Living Scale and MMPI scales for drug addicts. The sample of 42 polydrug-dependent persons was court mandated into inpatient treatment as a condition of probation, parole, or furlough. Analysis of variance showed that addicts, like alcoholics, were less perceptually differentiated than normals. Correlational and/or multivariate procedures yielded significant relationships between differentiation, verbal and abstraction abilities, likelihood of cognitive impairment, and MMPI scales F, 1, 2, 3, 4, 6, 7, 8 and 0.

MMPI Dependency Scale norms for alcoholics and psychiatric inpatients.

The MMPI Dependency (DY) Scale has a significant number of items that do not fall within the MMPI Form R format. The present study provides norms for the DY based on Form R responses from 1,505 male and female hospitalized psychiatric patients and alcoholics. While females had higher DY scores than males, alcoholics and psychiatric patients did not differ. It was found that T scores for a Form R version of the DY scale can be obtained easily from previously published DY norm tables.

A statistical audit of the clinical utility of the 168 version of MMPI.

Measured MMPI protocols from 347 female and 563 male psychiatric patients according to the standard form and the 168 version. Clinical scales were derived and profiles were classified using the procedure of Marks, Seeman, and Haller (1978). Approximately 50% agreement between MMPI-168 and full scale profiles was obtained. Most disagreements tended to be clinically important. On a simple psychopathology/nonpsychopathology dichotomy, between 75 and 80% agreement occurred.

Psychological health of young adults who experienced early parent death: MMPI trends.

Psychological effects that result from childhood parent loss by death are of substantial clinical and research importance. Parent loss has been linked with various psychopathology, though little is known of its effects on subsequent psychological health (a) as a function of the child's sex; (b) in normal individuals; (c) where early parent separation also has occurred. This study provides data on the Minnesota Multiphasic Personality Inventory-168 (MMPI-168) that address these issues. Ss were normals (16 males and 16 females per group) divided into three groups: Early bereaved (up to age 7), late bereaved (ages 12 to 18), and nonbereaved. In 50% of the bereaved individuals, two or more MMPI-168 clinical scales were pathologically abnormal compared with 28% of controls. Significant parent loss by child's sex interaction effects were obtained on Psychopathic Deviate, Masculinity-Femininity, Psychasthenia, and Schizophrenia scales. A significant effect was found for early parent separation on the Schizophrenia scale.

Diagnostic implications of markedly elevated MMPI Sc scale scores for nonhospitalized clients.

Evaluated the personal adjustment of counseling center clients (N = 60) whose MMPI's highest scale score was a Sc over 70. Analysis of case notes showed that while these clients posed more difficult counseling problems than the average client, the severity of disturbance was markedly less than one would expect from a sample with a mean Sc score of 91. An exploratory stepwise regression analysis indicated that chronic adjustment correlated significantly, R = .79, to an equation in which Sc, MA, R, DY, and Do had positive coefficients and HY, ES and CN negative coefficients. This regression equation also related significantly to the incidence of role identity problems, p less than .01; counselor judgment of client improvement, p less than .001; and bizarre ideation, p less than .001. Consideration of present client stress and prior adjustment factors was discussed as important in formulating less psychopathological interpretations for MMPI profiles with markedly elevated Sc scores.

The schizophrenia spectrum: a study of the relationship among the Rorschach, MMPI, and visual backward masking.

Compared 20 Ss within the schizophrenia spectrum and 20 non-schizophrenia spectrum controls in terms of their MMPI and Rorschach performance. Ss also were studied in terms of their ability to identify a briefly exposed visual stimulus when it was followed by a noninformational mask stimulus and when it was not. Ss did not differ on the MMPI or on their ability to identify an unmasked target stimulus. They differed significantly in the number of deviant verbalizations, a special scoring category of the Rorschach. Ss also differed in their ability to identify the briefly exposed stimulus when it was followed by the noninformational mask. Results indicated a relationship among the deviant verbalization, the masking procedure, and the schizophrenia spectrum.

Recidivism, perceived problem-solving abilities, MMPI characteristics, and violence: a study of black and white incarcerated male adult offenders.

This study examined recidivism, perceived problem-solving abilities, type of offense, and personality characteristics in an incarcerated male population. Twenty black males and 32 white males were selected systematically from inmate populations. The MMPI, its special scales, and the PSI scales were analyzed; F, L, Re, and Do scales reported significant results. Recidivists scored significantly higher than nonrecidivists on the impulsive scale of the Problem Solving Inventory. Black recidivists generated significantly higher scores on the F scale than did black or white nonrecidivists. The Pd scale reported a significant main effect for type of offense (p less than .05). Offenders incarcerated for violent crimes scored higher on the Pd scale than the nonviolent criminals. This research study demonstrated the utility of the MMPI and the PSI in discriminating between nonviolent and violent criminals.

MMPI correlates of clinical women who report early sexual abuse.

It was predicted from Freud's seduction theory that women who experienced sexual assault early in life would be identifiable by the MMPI. Twenty-six of 51 women treated at a psychotherapy clinic during a 2-year period reported experiencing sexual abuse as a child (RA); 25 made no such claim (NRA). Age, income level, years of formal education, marital status, and k-corrected scores of the MMPI were submitted to a stepwise multivariate discriminant analysis. It was found that the HY, MF, HS, and PD scales constituted a linear function that correctly classified 72.55% of the subjects (Wilkes Lambda = .670785, df 4, p = .0009). These scales correctly identified 73.1% of the RA and 72.0% of the NRA clients.

The diagnosis of personality disorder: a comparison of MMPI profile, Million Inventory, and clinical judgment in a Workers' Compensation population.

This study investigated information derived from a group of 100 Workers' Compensation cases and used clinical opinion and psychological testing to determine the presence and nature of personality disorder diagnosis. Tests used were the MMPI and the Millon Clinical Multiaxial Inventory. Patients were divided according to categories of presenting complaint. Significant differences were found on both the MMPI and the Millon among the diagnostic groups of personality disorders. The authors cautioned about the use of the Millon Test because of the extremely high numbers of personality disorders suggested by that test. In the discussion, attention was called to the complexities of personality disorder diagnosis when Axis I and Axis II diagnoses are present.

The reliability of a micro-computer administration of the MMPI.

A computerized version of the MMPI was developed that incorporated both administration and scoring. This method was compared with the original manual form (N = 87). The results indicated that the test-retest reliability was high regardless of the method of administration and that similar results were obtained on the computer and on the manual forms of the MMPI.

Estimation of MMPI scale scores from an improved comprehensibility short form.

Equations were derived for estimating MMPI scores from a short form that was developed for cognitively impaired individuals. Multiple regression analyses of the data on 300 patients demonstrated that prediction from a single short-form scale was acceptable and was little improved by the addition of other scales or sex of subject to the prediction equation. Substitution equations were constructed, and correlations of short-form scales with the full MMPI ranged from .82 to .96 with a median of .91.

A multimethod evaluation of the MMPI in a chronic pain patient sample.

Previous reports on the use of the MMPI with chronic pain patients have produced a variety of results. No single configural feature or scale identifies the chronic pain patient, regardless of the origin or verifiability of the etiology of the pain. Elevations on the neurotic triad occur frequently, but do not have the specificity of more recently reported chronic-pain subtypes on the MMPI. The present nonexperimental study (N = 72) provides an example of a multi-method analysis of a carefully selected sample of chronic pain patients without physical findings. Blind clinical analysis, simple two-point code aggregation, and multivariate profile methods were used and produced similar subtypes of the sample and understanding of the data. The obtained sample subtypes were similar to those found in other studies and were hypothesized to be related to each other along an underlying continuum of what might be depression. Further research is needed to facilitate understanding of the causation of chronic pain of obscure origin.

Resiliency reconsidered: contemporary MMPI normative data for Barron's Ego Strength Scale.

Although it is more than 30 years old, Es remains one of the most frequently scored of the MMPI supplemental scales. However, there have been significant changes in MMPI response patterns among adults since the Es scale was first developed. New normative tables for the Es scale based on a contemporary census-matched sample of normal adults are presented along with figures that illustrate changes associated with age and sex.

MMPI correlates of performance intellectual deficits in patients with right hemisphere lesions.

This study investigated the emotional adjustment of 50 patients with focal brain damage in the right hemisphere (RHD). The impact of functional loss (as assessed by the WAIS Performance IQ) was assessed by a multivariate comparison of the composite MMPI profiles of these patients as classified into three groups: Below Average, Average, and Above Average Performance IQ. Regardless of the extent of decline in Performance-related abilities, right hemisphere impairment was associated with symptoms of mild depression, loss of initiative, anxiety, denial, and somatic preoccupations. MMPI scores were not correlated significantly with their WAIS Performance IQs. Implications for neuropsychological assessment are discussed.

A summary of the reliability and stability of MMPI scales.

A sample of MMPI research published between 1970 and 1981 was analyzed to yield reliability and stability estimates for the MMPI scales. In fundamental agreement with previous research, moderately high levels of reliability and stability were found for all scales. Reliability values ranged from .71 to .84; stability values ranged from .63 to .86. These findings are based on thousands of adult subjects from college, psychiatric, medical, alcohol or drug rehabilitation, and prison populations. The present scale estimates have wide generalizability and, therefore, should be of value to clinicians and researchers in various settings.

Concordance of the MCMI and the MMPI in the diagnosis of three DSM-III Axis I disorders.

This study examines the diagnostic accuracy of the three clinical syndrome scales of the Millon Clinical Multiaxial Inventory for a representative psychiatric inpatient population (N = 103). These scales were designed to identify the following DSM-III Axis I disorders: Schizophrenia, major depression, and paranoid disorders. True-positive identification rate was found to be lower than that reported by Millon (1983) for psychotic disorders, despite (in the case of schizophrenia) high prevalence in the sample. A comparison with the MMPI revealed the latter to be more accurate than the MCMI in the identification of schizophrenia and major depression and less accurate in the identification of paranoid disorders. While the MCMI did identify successfully .50 of the paranoid disorders in the sample, the prevalence of these disorders was very low (.02). These findings argue strongly against the use of the MCMI as an alternative to the MMPI in inpatient psychiatric settings.

Use of the MMPI and MCMI in predicting outcome of lumbar laminectomy.

This study compared the abilities of the MMPI and Millon Clinical Multiaxial Inventory (MCMI), using discriminant analyses, to predict outcome after lumbar laminectomy for chronic back pain. Sixty-nine males and 60 females with lumbar discogenic disease completed MMPIs and MCMIs before surgery and were classified as either having good or fair/poor surgical outcomes based on self-reported pain relief, return to work, restriction of activities, and medication use. Results showed both the MMPI and MCMI to have moderate ability to predict surgery outcome. A slightly higher classification hit rate was obtained with both instruments when age, sex, employment status, and presence of compensation/litigation issues also were entered into the prediction equation. Results indicate the need for caution in using either instrument to make predictions of surgery outcome in individual cases.
