The use of the MMPI-2 for the assessment of depressive and psychotic disorders.

Considering the normative changes incorporated into the MMPI-2 and the introduction of content scales, this study examined its usefulness for the diagnosis and assessment of depression and psychosis in a heterogeneous sample of 264 psychiatric inpatients. We examined the mean group profiles and diagnostic efficiency of single scales at specified cutoff scores for these conditions. We also conducted cross-validated stepwise regression using all the basic and content scales as well as hierarchical regression examining the incremental validity of the basic and content scales. In general, the MMPI-2 profiles were found to be sensitive to group differences and the derived regression equations proved to be stable and fairly good at classification; but single scales were less useful for diagnosis. Changes in norms made the MMPI-2 more specific than the MMPI, and the introduction of new content scales offered considerable additional clinical information and incremental validity.

Race and the differential "power" of the MMPI.

The interpretation that blacks' tendency to score higher on MMPI clinical scales is due to educational deprivation has been challenged by research in which, when educatation was held constant, race-related differences remained. Racial differences in type of psychopathology have seldom been controlled in part research. After establishing that a grester proportion of black psychiatric patients may receive a schizophrenic diagnosis (Study 1), MMPI protocols of black and white schizophrenic and nonschizophrenic psychiatric patients were obtained. All patients had received 12 or more years of education. Schizophrenics scored significantly higher on the MMPI F and Sc scales and nonschizophrenics tended to score higher on Pd. No race-related differences were observed on any of the 11 MMPI scales considered.

An evaluation of an MMPI response consistency measure.

Response inconsistency as an index for invalidating MMPI protocols was investigated by measuring the number of inconsistent responses given to 14 pairs of identical items by brain-damaged and nonbrain-damaged schizophrenic, alcoholic, neurotic and normal patients (n = 22 in each of the 8 groups). In addition the patient's number of inconsistent responses were correlated with the usual MMPI validity measures (?, L, F and K). Although all the response consistency scores of the groups were high it was found that the brain-damaged were more response inconsistent than the nonbrain-damaged patients (regardless of psychiatric diagnoses). The correlations between response inconsistency and the MMPI validity measures were significant but low. Because of the over-all high level of response consistency found for all the groups, it was concluded that MMPI protocol validity should be based on the validity scale measures, rather than upon response inconsistency.

MMPI criteria for diagnosing schizophrenia.

An attempt was made to find a combination of MMPI scale relationships which were highly discriminating of schizophrenia. Through the use of a standardized structured interview and a diagnostic system for schizophrenia based on the use of discriminant function analysis with nonpathognomonic symptom combinations, a reliable and valid system was used to establish the criterion diagnosis. Approximately 72% of patients reliably diagnosed as schizophrenics were detected on the MMPI via a set of standard criteria (T score on Sc greater than or equal to 80 less than or equal to 100; total raw score on Sc consisted of no more than 35% K items; T score on F greater than or equal to 75 less than or equal to 95; T score on Pt less than or equal to Sc). Only 5.5% of nonschizophrenics obtained all these standard criteria on the MMPI. The assets and liabilities of these MMPI criteria to diagnose schizophrenia are discussed.

Correspondence between psychological reports based on the Mini-Mult and the MMPI.

In order to assess the utility of the Mini-Mult with a university counseling center clientele, MMPI answer sheets of 10 students at the University of Miami Counseling Center were scored for both the MMPI and the Mini-Mult. Four judges completed psychological reports (Q-item questionnaires) based on the profiles. Correlations between judges' responses to MMPI and Mini-Mult profiles were calculated as an indication of the correspondence between the two tests. In addition, correlations between judges' responses to repeated presentations of MMPI profiles were calculated as an indication of the judges' reliability over time. The results do not support the use of the Mini-Mult with a university counseling center clientele.

A survey of MMPI teaching in APA-approved clinical training programs.

A questionnaire on teaching of the MMPI was sent to all APA-approved clinical training programs. The questionnaire asked the faculty member primarily responsible for teaching the MMPI to indicate how much emphasis was placed on it, how they made use of it, and how valuable it was felt to be. A return rate of 83% was achieved. It was found that: a) 92% of the responding programs offer courses dealing with the MMPI; b) 74% of the programs that teach the MMPI put major emphasis on it; c) emphasis placed on the instrument is holding steady; d) instructors with 10 years or less teaching experience rate the test as highly and are as likely to use it outside the classroom as their more experienced colleagues.

Homogeneous scales for the neurotic triad of the MMPI.

This study used item statistics for the nonduplicated items of the MMPI and the CPI to develop homogeneous scales for the neurotic triad (Hs, D, Hy) of the MMPI. The construction and partial cross-validation of scales were based on data from a predominantly clinical sample of 563 male subjects and 347 female subjects. Two non-overlapping scales of high internal consistency were developed which contained embedded subscales designed to be relatively independent of factor dimensions previously identified in the data. The first of the two scales comprised items exclusively related to health concern, and the second was a more concentrated measure of poor morale than the MMPI Depression scale. The nature of the revised scales was analyzed in relation to the standard MMPI scales and factor dimensions from previous research. Implications of the study for development of an hierarchical inventory were discussed.

Efficiency of local MMPI norms in the detection of psychopathology.

The standard MMPI was compared with the MMPI based on local norms for hit rate between a patient and nonpatient sample. Using the patient group only, a comparison was also made between the two sets of norms to determine their differential influence on profile height and configuration. The standard MMPI produced a significantly better hit rate overall (80.2%) than did the MMPI with local norms (71.8%). Standard norms produced significantly higher means for all scales except Si. A majority of single scale and two scale high points were different under the two sets of norms. It is concluded that the standard norms are more effective among these subjects than are the local norms. Results also indicate that the usual interpretations applied to scale elevations with the standard norms may not be applicable when other norms are used.

The MMPI in evaluation of functional versus organic low back pain.

This paper reviews the research literature on MMPI assessment of functional versus organic low back pain (LBP). Research is described in three categories: (a) the relationship between psychopathology as measured by the MMPI and low back pain, (b) MMPI speciality scales, and (c) surgical outcomes. Research, to date, has suffered from methodological problems which has limited generalizations to clinical population. It is suggested, however, that the MMPI can be effectively used with LBP patients, but should not be the only data used in such assessments. Cautions are noted regarding use of the speciality scales.

The influence of elevated F scales on the validity of adolescent MMPI profiles.

The Minnesota Multiphasic Personality Inventories (MMPI) of adolescent outpatients were examined to determine whether characteristically elevated F scales indicated an exaggeration of psychopathology. A treatment condition designed to reduce the motivation to exaggerate psychopathology did not lower scores of the F and F-K indices when subjects were administered a second MMPI. Similarly, actuarial interpretations for the second protocols were not more frequently selected by therapists as more valid, regardless of treatment condition and elevation of the F and F-K indices on the first MMPI profile. Elevations of Scales F, Pd/4, and Sc/8 characterized the adolescent MMPI profiles.

Comparison of the MCMI and MMPI-168 as psychiatric inpatient screening inventories.

The Millon Clinical Multiaxial Inventory (MCMI) has been recently developed as an alternative to the Minnesota Multiphasic Personality Inventory (MMPI) and shares some of its psychometric advantages and disadvantages with the MMPI-168, a short form of the MMPI. The current study compared the structure and utility of the MCMI and MMPI-168 for a general hospital inpatient psychiatric population. Overall, the two instruments were highly correlated and found to have conceptually similar factor structures. Empirical comparison of the factor structures indicated that construct validity is greatest for neurotic traits. Both instruments demonstrated a similar utility in predicting discharge diagnosis.

The detection of malingering in criminal forensic groups: MMPI validity scales.

Despite the value of the MMPI to the forensic assessment of malingering (exaggeration) of psychopathology, few studies have assessed the accuracy of the MMPI validity scales in criminal forensic populations. We administered the MMPI to 35 insanity defendants undergoing evaluation for fitness to stand trial and/or sanity at the time of the crime, who stood to benefit from being assessed as psychologically disturbed, and 39 subjects previously found not guilty by reason of insanity (NGRI), who did not stand to gain from such an assessment, Insanity defendants showed significantly more malingering than NGRI subjects, p less than .05. Racial differences did not affect the data. These findings support the efficacy of MMPI validity scales in assessing malingering within criminal forensic groups, and support the generalizability of the scales across race.

MMPI and Rorschach indices of schizophrenic and depressive diagnoses among adolescent inpatients.

Although adolescent norms have been developed for the MMPI (e.g., Marks, Seeman, & Haller, 1974) and Rorschach (e.g., Exner, 1986a), little is known regarding the discriminate diagnostic validity of these measures with adolescents. This study investigated the usefulness of these measures in the detection of depression and schizophrenia among adolescent inpatients. Subjects (mean age = 15.3) consisted of 134 adolescents who received Rorschach and MMPI administrations at hospital admission. Clinical diagnoses resulted in the following groupings for this sample: schizophrenia = 15, dysthymic disorder = 41, major depression = 26, conduct disorder = 28, personality disorder = 18. MMPI scale Sc elevation was found to be the most effective single predictor of schizophrenic diagnoses, with a hit rate of .76, sensitivity of .62, and specificity of .78. Neither MMPI scale D scores nor Rorschach DEPI scores were found to be significantly related to patients' diagnoses. Results were interpreted in terms of prior findings in adult psychiatric populations and in relation to implications for the clinical assessment of adolescents.

WAIS-R and MMPI profiles of men who have sexually assaulted children: evidence of limited utility.

Wechsler Adult Intelligence Scale-Revised (WAIS-R) data were compiled on 101 male sexual offenders of children, and Minnesota Multiphasic Personality Inventory (MMPI) profiles were compiled for a subsample of 81 of these subjects in a replication and extension of the Hall, Maiuro, Vitaliano, and Proctor (1986) MMPI study. The MMPI profiles were heterogeneous and had multiple elevations. No significant relationships between the WAIS-R Full Scale IQ, WAIS-R Performance IQ Minus Verbal IQ Index, or the MMPI scales, and offense characteristics were obtained. These results support the hypothesis of Hall et al. (1986) that psychometric instruments may be of limited utility in characterizing or differentiating among sexual offenders on the basis of criminological variables.

MMPI correlates of Exner's Egocentricity Index in an adolescent psychiatric population.

This research examined the relationship between Exner's Egocentricity Index (EI) and Minnesota Multiphasic Personality Inventory (MMPI) Scales 2, 4, and 9 in an adolescent psychiatric population. Subjects with a low EI had significantly higher MMPI Depression (D) scale elevations compared to those with a high EI. Furthermore, of the adolescents who had Scale 2 scores in the clinical range, 68% also had an EI in the bottom half of the distribution. There was no relationship between the EI and MMPI scales 4 and 9. These findings are discussed in light of the generally poor correlations between MMPI and Rorschach variables.

An MMPI typology of cocaine abusers.

Three types were found in a cluster analysis of scores on the Minnesota Multiphasic Personality Inventory (MMPI) of 100 men voluntarily presenting for treatment of cocaine abuse. Type 1 (n = 59) had a mean MMPI profile consistent with the hypothesized grouping of persons who self-medicate with cocaine as a means of overcoming depression. The relatively normal mean MMPI profile obtained by Type 2 (n = 37) suggested little indication of significant psychopathology. Type 3's (n = 4) mean MMPI profile suggested either severe disturbance or profile invalidity. Types were found to differ in the nature of drug use, reactions to cocaine, education level, and social class, but not on the scales of the Adjective Check List.

Relationships between the MAPI and the MMPI in the assessment of adolescent psychopathology.

Although the Minnesota Multiphasic Personality Inventory (MMPI) and the Millon Adolescent Personality Inventory (MAPI) are both widely used in the clinical assessment of adolescents, no research has examined the interrelationship between these two instruments. We investigated MMPI and MAPI responses from 199 adolescents assessed at entrance to inpatient or outpatient psychiatric programs in Florida and Virginia. Univariate correlation analyses identified areas of significant associations between these measures, with coefficients ranging widely from -.70 to .72. Substantial diagnostic differences were found between these instruments. The MAPI, for example, yielded no depression-related diagnoses, but produced many more adjustment disorder and personality disorder diagnoses than the MMPI. The rates of diagnostic assignment agreements between diagnoses produced by clinical judgment, MMPI findings, and MAPI interpretive reports were typically quite low.

Combining the Rorschach and the MMPI in the assessment of adolescents.

We examined empirical findings related to the integration of the Rorschach and the MMPI in assessing adolescents. Intercorrelations between 50 Rorschach variables and the 13 MMPI basic scales are reported for a clinical sample of 197 adolescents. Significant correlations only slightly exceeded the number expected by chance. A review of six additional studies of adolescent samples also generally revealed either very modest or nonsignificant relationships between the Rorschach and the MMPI. These findings leave open the possibility that combining data from the two instruments may increase incremental validity, an issue that should be assessed by using multivariate analyses. Guidelines for integrating Rorschach and MMPI data in clinical practices with adolescents are provided.
