The diagnostic use of the MMPI in organic brain dysfunction.

Investigated two problem areas: (a) difficulty in the diagnoses of some types of organic brain dysfunctions; and (b) lack of accuracy in the differentiation of patients with organic disorders from patients with nonorganic disorders. Hospitalized male Ss (N = 152) were selected by diagnoses to form one nonorganic and three organic groups. For each group, data from Ss' MMPI protocols were analyzed via Cattel's Coefficient of Profile Similarity and discriminant analysis. Both MMPI factor scales (Barker, Fowler, & Peterson, 1971) and the usual clinical scales were used and compared in all analyses. Statistically significant differences among groups were found on both scales, with a greater separation of the groups provided by the factor scales. Results suggest that the MMPI, through the use of regression formulas derived from discriminant analysis of multiple groups, may be of diagnostic utility in organic brain dysfunction.

Utility of the Faschingbauer abbreviated MMPI as a function of patient group and sex.

Assessed the utility of the 166-item FAM with medical and psychiatric patients. FAM items were extracted from MMPI data of 60 female and 45 male patients classified into pain and psychiatric patients based on suspected disorder and referral questions. Although all correlations between FAM and MMPI mean T-scores on all scales were highly significant, 54% of the means were significantly different. The number and the nature of the difference between FAM and MMPI group means and individual profile classifications varied as a function of patient subgroup and sex. Such subgroup delineation of FAM accuracy is discussed as necessary for decisions about appropriate clinical and research utilization.

The relationship between various dietary factors and MMPI subscales: implications for clinical practice.

Examined specific relationships, as they occur in nature, between particular dietary variables or groups of variables and specific MMPI subscales. Detailed nutritional and demographic information and MMPI profiles were obtained from 20 adult psychiatric inpatients, 10 adult psychiatric outpatients, and 20 adult normals. A linear multiple regression analysis revealed strong relationships between a number of dietary variables and MMPI subscales. Implications for future research and clinical practice were discussed.

Validity of a back pain classification scale for detecting psychological disturbance as measured by the MMPI.

Constructed a Back Pain Classification Scale (BPCS) to detect serious psychological disturbance in low back pain patients, validated against the MMPI. One hundred and twenty patients with low back pain were classified as functional or organic on the basis of BPCS scores. The group identified as psychologically disturbed (functional) had significantly higher MMPI elevations on Scales F, HS, D, HY, PD, MF, PA, PT and SC. None of their scale scores was significantly lower than the group identified as organic. T-scores above 70 were present only on Scales 1 and 3, which suggests a high incidence of essentially neurotic disorders in patients classified as functional. The use of the BPCS as a viable alternative to the MMPI in the medical setting was discussed.

Multivariate analysis of WAIS-MMPI relationships among brain-damaged, schizophrenic, neurotic, and alcoholic patients.

Subjected WAIS and MMPI profiles of brain-damaged, process schizophrenic, reactive schizophrenic, neurotic, and alcoholic patients (N = 423) to multiple discriminant and canonical correlational analyses. The groups differed significantly in WAIS and MMPI profile patterns, and the combination of both sets of measures resulted in increased group discrimination compared to either set alone. Nonetheless, despite this element of independence in their contributions to group differentiation, WAIS subtests and MMPI scales were correlated with each other along two significant profile dimensions. The results were seen to provide a multivariate description of intelligence and personality as partially overlapping domains that contain both shared and unique components of variance.

Discriminative dimensions of the MMPI as a function of age and psychopathology.

Investigated the discriminative ability of the MMPI validity and clinical scales with schizophrenic and nonschizophrenic patients across various age levels. Two hundred psychiatric inpatients comprised the sample. Results suggest that age does affect MMPI scale scores of psychiatric inpatients and that schizophrenic and nonschizophrenic patients present divergent MMPI profiles for the two groups studied. Comparability with earlier findings and interpretive trends are offered.

The use of the MMPI in a chronic back pain rehabilitation program.

Assessed the usefulness of the MMPI in predicting treatment outcome for chronic low back pain patients. One hundred and thirty-two chronic low back pain patients who participated in a 6-week rehabilitation program were differentiated according to "successful" outcome. Outcome was defined in three major ways: Vocational restoration, significantly improved physical mobility, and patients' subjective evaluations of improved functional level. Pretreatment MMPIs of all outcome groups were compared. Data were analyzed by examining individual scale scores and code-types and by applying multiple regression analyses to the data. Results demonstrate that the MMPI can predict successful outcome. However, the strength of the relationship varies according to the outcome measure employed and the type of analysis completed on the data. It is concluded that, though an interesting research tool, at this time the MMPI is not a consistently valid clinical tool with the chronic back pain population in terms of predicting response to rehabilitation.

Frequency of MMPI profile types in three chronic illness populations.

Clinical interpretation of the MMPI most often utilizes configural or profile analysis. However, most MMPI research has focused only on single scale comparisons. In this study sorting rules to identify four common MMPI configurations were developed and applied to four S populations (N = 157): Chronic low back pain patients, migraine headache patients, hypertensives, and diabetics. No differences in frequencies of these profile types were found among the groups, although the chronic low back pain patients did have more elevated profiles. Variables of age, chronicity of illness and gender did not seem to influence profile type, while some differences were found between patients who rated themselves high and low in activity limitation due to the illness.

A comparison of six MMPI short forms: code type correspondence and indices of psychopathology.

Compared six MMPI short forms for their ability to identify code-types and indices of psychopathology obtained from the full length MMPI for samples of renal dialysis patients (N = 53) and paranoid schizophrenics (N = 58). Results suggest that the accuracy of the short forms fluctuates for different patient populations and diagnostic criteria. The longer abbreviated forms are generally more accurate, especially the MMPI-168 and the FAM.

The MMPI: development of contemporary norms.

The original standardization of the MMPI was completed approximately 40 years ago. These norms were refined in 1957, but no attempt has been made to develop new standards. Therefore, a contemporary random sample of 1,408 persons living in the midwestern states who were similar to the original sample in area of residence and in the absence of significant medical problems were asked to complete the MMPI. The resulting MMPI data by age and sex are presented. In general, responses from this contemporary sample yielded higher mean scores than appeared in the original standardization group. These data suggest a somewhat more conservative approach to profile interpretation, with more careful consideration of the impact of age and sex on profile configurations.

Suicide and the MMPI: a cross-validation of predictors.

Compared a suicide-completion group to a psychiatric control sample on the 13 traditional MMPI scales, three experimental item pools, and eight profile patterns earlier described as indicative of suicidal tendencies (N = 84). Also compared the frequencies with which the groups endorsed each of the 566 MMPI items. The number of resulting significant differences was less than chance. The results argue against the use of the MMPI to predict suicide at this time.

Relationship between the Luscher Color Test and the MMPI.

Administered the short form of the Luscher Color Test and the booklet form of the MMPI to 42 graduate students in a counseling program. For every S a report that described personality was written from the test results, i.e., each S had two reports, one from the Color Test and one from the MMPI. These reports were written independently by two separate examiners. Two independent raters then read the reports on each S and noted the degree of agreement between the two reports. The overall results showed very little agreement between the Color Test and the MMPI. Reasons for the poor rate of agreement are discussed.

Normative data for two MMPI critical item sets.

Addressed normative aspects of recent MMPI critical item sets proposed by Koss and Butcher (1973) and Lachar and Wrobel (1979). Base rates from MMPI Form R for these items were determined in samples of 123 normals, 383 inpatient alcoholics, and 567 psychiatric inpatients. Although pathological groups, as expected, generally endorsed more critical items than normals, mean differences were not large. On several critical item subsets, especially in the Koss -Butcher group, normals actually scored higher than the pathological samples. Caution is suggested when critical MMPI items are used in assessments.

MMPI correlates of relatively localized brain damage.

Examined the MMPI correlates of relatively localized brain damage classified along dimensions of laterality and caudality. Forty patients with lateralized lesions that involved anterior or posterior cerebral areas were studied. Based on a multivariate analysis of variance, results revealed significant differences in MMPI profiles between left hemisphere and right hemisphere lesion groups. The MMPI profile for the left hemisphere lesion group is well within the normal range; the right hemisphere lesion group is beyond normal limits, primarily on scales 8 and 2. Several issues are discussed in an effort to integrate these findings with previous studies.

MMPI correlates of verbal-intellectual deficits in patients with left hemisphere lesions.

This study investigated the emotional adjustment of patients (N = 31) with left hemisphere damage (LHD) as a function of the degree of impairment in verbal intelligence as measured by the Wechsler Adult Intelligence Scale. A multivariate comparison was made of the composite MMPI profiles of three groups of LHD patients classified according to Verbal IQ. The three groups produced fairly similar composite profiles, which indicated the presence of mild dysphoria, dissatisfaction, withdrawal, decreased initiative, and mild somatic preoccupations. Significant correlations emerged between the degree of verbal-intellectual disability and MMPI F, PT, SC, and SI. However, when the variance in MMPI scores due to premorbid status (education) was partialled out, these correlations dropped to nonsignificant levels. These findings failed to support previous studies that linked verbal deficits with emotional disturbance, and they underscore the importance of premorbid intelligence in the psychological adjustment to organic impairment.

An MMPI scale to predict premature termination from inpatient alcohol treatment.

This study developed an MMPI scale to predict premature termination of patients from inpatient alcohol programming. MMPI responses of 93 male veterans hospitalized in a 4-week alcohol treatment program were item analyzed, and 21 items that differentiated Completers from Dropouts were selected. A classification accuracy rate of 91.36% was achieved in the standardization sample using a cut-off score of 8 and comparing only valid profiles. Classificatory accuracy of a cross validation sample (N = 90) was somewhat lower (75.34%). Face validity was absent, an indication of the scale's subtlety, and an analysis of scale items' Social Desirability Scale Values indicated that social desirability did not appear to influence item endorsement. Consistent differences between Completers and Dropouts were noted on Scales F and Sc, but not over other MMPI clinical scales, age, and race. Methodological issues and the use of the scale in alcohol treatment programming also were discussed.

MMPI scales and subscales: patterns of older, middle-aged, and younger inpatients.

There has been virtually no research on the relationship of age and MMPI subscales, such as the Harris and Lingoes, Wiggins, Subtle/Obvious, and other specialized subscales. One hundred younger (less than or equal to 39), middle-aged (40-49), and older (greater than or equal to 50) psychiatric inpatients were compared on the basic 13 MMPI scales and 77 MMPI subscales. Results showed that, as a whole, older patients tended to respond more conservatively to these scales, to show less pathology, and to endorse fewer subtle/obvious items than the other age groups. They responded, however, lower on Dominance, on Hostility, and on Social Maladjustment. Later-life patients also endorsed differentially many of the Harris and Lingoes 4 and 6 subscales in the less pathological direction than did the other groups.

The assessment of denial and physical complaints: the validity of the Hy scale and associated MMPI signs.

Little and Fisher (1958) have demonstrated that the MMPI Hysteria (Hy) scale consists primarily of items that address the denial of psychological problems (the DN scale) and items that involve the admission of physical problems (the AD scale). The traditional interpretation of an elevated Hy score implies that both DN and AD subscales are elevated significantly. Using samples of psychiatric (N = 1,246), medical (N = 330), and chronic pain patients (N = 126), the effectiveness of the HY scale and of various combinations of MMPI scales as predictors of the simultaneous occurrence of these two characteristics was evaluated. The results suggest that when the 13 standard MMPI scales were used, simultaneous elevations on scales K, HS, and HY proved to be the best indicator of the denial of psychological factors associated with a physiological disorder. It was found unwarranted to suggest the presence of hysteroid features on the basis of an elevated HY score unless scales K and HS also were elevated. The value of the HY scale as a measure of psychological denial associated with physical complaints must be considered questionable.
