A comparison between the Minnesota Multiphasic Personality Inventory and the 'Mensana Clinic Back Pain Test' for validating the complaint of chronic back pain.

Reports on the efficacy of the Minnesota Multiphasic Personality Inventory (MMPI) for selecting patients with valid complaints of pain have been equivocal. The Mensana Clinic Back Pain Test (MPT) was able to predict, with some degree of success, patients who had a definite organic pathologic condition. However, the MMPI measures personality traits, whereas the MPT measures the impact of pain on a patient's life. To determine which of the two tests would be a better predictor of actual physical abnormalities, and hence valid pain complaints, a comparison was undertaken between the two tests. The charts of 83 patients admitted to the Neurosurgery Service of Johns Hopkins Hospital with complaints of back pain were assessed. MMPI test results, as well as test results for the MPT, were compared to the presence or absence of pathologic conditions on electromyography, nerve conduction velocity studies, thermography, myelogram, or computerized axial tomography scan. The MPT had a correlation factor of -.59700, that was significant as P = .000005. Of the 52 patients scoring 17 points or less on the MPT, 85% had objective physical abnormalities, considered moderate or severe by blind review. Of the 31 patients scoring 18 points or greater on the MPT, only 26% had objective physical findings that were considered moderate or severe. Only the F scale (faking badly) of the MMPI correlated with objective physical abnormalities (r = .21340, P less than .033). However, 60% of the patients with T scores of less than 70 on the F scale had objective findings, whereas 75% of patients with T scores greater than 70 had objective physical findings.(ABSTRACT TRUNCATED AT 250 WORDS)

Development of the Multi-Trait Personality Inventory (MTPI): comparison among four Chinese populations.

Anemic approach was adopted to develop a culture-specific instrument for the assessment of Chinese personality. The Multi-Trial Personality Inventory (MTPI) was administered to 1,673 men and 944 women in four major Chinese populations. It was found that Chinese in mainland China, Taiwan, Hong Kong, and the United States possess some common traits deeply rooted in the Chinese culture characterized by Confucian thoughts (e.g., self-discipline and moderation) and some additional traits nurtured by their respective environments. Consequently, findings of this study lent support to the hypothesis that, in spite of superficial discontinuities, there are basic continuities in the personality traits of mainland and overseas Chinese. The cross-cultural differences in personality were examined from a political-social perspective and also explained with a cultural-ecological model. In the development of the MTPI, a new methodology that relies on forming factor-consistent clusters was employed to deal successfully with the problem of complex factor space.

Pain-patient Minnesota Multiphasic Personality Inventory (MMPI) subgroups: evaluation of long-term treatment outcome.

Six hundred thirty-five chronic pain patients completed the Minnesota Multiphasic Personality Inventory (MMPI) prior to participation in a multidisciplinary inpatient pain treatment program. Three male and four female MMPI subgroups were identified by means of cluster analyses for each of two samples. Pretreatment and long-term follow-up differences were then examined among the MMPI subgroups. Results indicated that the subgroups identified in the present study closely resembled each other and those previously reported in the literature. However, at long-term follow-up only a few outcome differences were identified among male subgroups, while no differences were found among female subgroups. Possible explanations for no differential treatment outcomes among the MMPI subgroups are discussed.

Brief Minnesota Multiphasic Personality Inventory scales to screen for substance abuse.

Research has focused on development of accurate screening instruments to detect alcoholism. The Minnesota Multiphasic Personality Inventory (MMPI) has long been employed, but the utility of previous scales in differentiating substance abusers from normals remains unclear. Conley and Kammeier (J. Consult. Clin. Psychol., 48 (1980) 665) identified seven MMPI items which appeared to be specific to alcoholism. In a replication attempt, this study compared MMPI's for 1403 male and 323 female job applicants and 228 male and 76 female chemical dependency inpatients. MMPI items were chosen through empirical identification of those with greatest endorsement differences. A 13-item scale emerged with an endorsement differential exceeding 45%. Four of the seven Conley-Kammeier items replicated in the 13-item scale. These shorter MMPI scales appear superior to the older 50-item-plus MacAndrew and Holmes scales for screening normal populations, providing cutting scores which yield specificity exceeding 80% with sensitivity greater than 90%. However, results must be interpreted with caution, and limitations regarding the state of the art are set forth.

Relationship between the "cognitive triad" from the personality inventory for children and an extended Halstead-Reitan neuropsychological battery.

The relationships between the Achievement, Intellectual Screening, and Development scales from the Personality Inventory for Children (PIC) and a comprehensive neuropsychological battery were examined in a sample of 49 children with histories of behavioral problems, learning problems, or both but without known neurological impairments or pervasive developmental disorders. Using stepwise multiple regression, the PIC scales predicted global neuropsychological functions moderately well, particularly verbal IQ and achievement. More specific neuropsychological functions were not significantly predicted. The Developmental scale from the PIC consistently outperformed the other two PIC "cognitive-triad" scales, and the latter made no statistically significant additional contribution in predicting neuropsychological functions after the contribution of the Development scale was taken into account.

[Gastro-esophageal reflux, personality study by the Minnesota Multiphasic Personality Inventory (MMPI)].

Gastro-esophageal reflux (GER) is often associated with other functional digestive manifestations. The subjectivity of these manifestations permits an in-depth study of the personality of these patients as compared to a regional reference population with the use of the Minnesota multiphasic personality inventory. In these patients suspected to have a gastro-esophageal reflux, the means to the scales are modified except for that of the psychopathy scale, which is reassuring considering its severity. However, no personality profile may be exteriorized. The difference between patients with GER certified or not by pH measurement rests on the predominance of neurotic scales in the group presenting a gastro-esophageal reflux certified by pH measurement. This results appears to be due to the disease itself rather than to the conditions of performance of the MMPI during pH measurement. Only a pre- and post-therapeutic study will enable to confirm these data.

Chronic pain and the questionable use of the Minnesota Multiphasic Personality Inventory.

Several studies have observed that patients who complain of chronic pain have significantly elevated scores on the first 3 clinical scales of the Minnesota Multiphasic Personality Inventory (MMPI). Some studies imply that this profile allows one to conclude that such patients exaggerate their symptoms, have strong feelings of inadequacy, have emotional problems which are neurotic, with implications that this is functional pain. The present study and its results challenges the use of the MMPI in attempting to distinguish psychogenic from organic pain. The MMPI was administered to 62 patients on their admission to the hospital. All 62 patients had a diagnosis of some organic findings consistent with their pain symptomatology. The average MMPI scores resulted in an elevated "Conversion-V" profile. It was also noted that as characteristics such as age of the subject, number of surgeries, and number of physicians seen increased, there was a corresponding increase in the neurotic scales. It was concluded that utmost caution should be used in interpreting individual pain patients' MMPI scores. It is especially important to avoid dismissing the pain symptomatology as functional by simply giving the patient a psychiatric diagnosis consistent with the profile. The potential of the MMPI as an aid in developing the treatment plan and as a possible predictive tool for certain treatment procedures is discussed. It is suggested that MMPI data be collected on a comparison group of patients, who have had successful relief of pain through surgical intervention.

An investigation of the relationship between psychopathic traits and malingering on the psychopathic personality inventory.

This study employed a repeated-measures simulation design to examine (a) the specific effects of malingering on a recently developed measure of psychopathy, the Psychopathic Personality Inventory (PPI), and (b) the broader association between psychopathic traits and dissimulation. One hundred and forty-three participants completed the PPI twice (both under standard instructions and with instructions to feign psychosis), and also completed post-test questionnaires assessing their attitudes toward engaging in malingering across several hypothetical settings. When attempting to feign psychosis, participants produced elevated scores on a validity scale designed to identify deviant responding, and use of a cross-validated cutoff score with this scale produced high sensitivity and specificity rates across the honest and malingering conditions. Furthermore, PPI scores (in the honest condition) were significantly correlated with a willingness to engage in dissimulation across various hypothetical forensic/correctional scenarios. Results are discussed in terms of the "fakability" of the PPI, as well as the relationship between psychopathic personality features and malingering more generally.

The relationships among the Hoffer-Osmond Diagnostic Test, the Minnesota Multiphasic Personality Inventory, and independent clinical diagnoses.

A study was conducted to determine the relationship between two tests in the detection of schizophrenia. One of the tests used was the Minnesota Multiphasic Personality Inventory (MMPI) and the other, a less familiar test, was the Hoffer-Osmond Diagnostic Test (HOD). Also investigated was the difference between the MMPI and the HOD when compared to independently made clinical diagnoses. Of 100 outpatients examined, 75 with valid test results were used. It was hypothesized that the correlation between HOD scores and the Schizophrenia and Paranoia t-scores on the MMPI would be significant. Also, no difference between the two tests and comparable clinical diagnoses was expected. The predicted effects were found. Possible preference for the HOD under certain circumstances was discussed.

Study of psychopathology in patients with chronic non-lesional epilepsy: a Minnesota multiphasic personality inventory profile controlled study.

OBJECTIVE: Psychiatric morbidity and psychopathology have been widely assessed in patients with epilepsy. However, the issue of whether people with epilepsy are at increased risk for psychopathology remains highly controversial. These disorders are not evaluated in a systematic manner in patients with non-lesional epilepsy, so they could be underestimated. The objective is to evaluate personality disorders in patients with non-lesional epilepsy. METHODS: In this study, we investigated the presence of personality disorders in 63 patients with chronic non-lesional (idiopathic and cryptogenic) epilepsy and in 40 unrelated and randomly selected controls by means of Minnesota Multiphasic Personality Inventory (MMPI) and DSM-IV criteria for the different personality disorders. RESULTS: The overall scores were significantly higher in the patients in the subscales of schizophrenia, depression, hysteria, mania, paranoia, psychasthenia and psychopathic deviate. However, the differences in the proportion of patients with clinically significant scores occurred only for schizophrenia (57 vs. 20%), depression (55 vs. 15%), psychasthenia (28 vs. 10%) and paranoia (14 vs. 0%). According to DSM-IV criteria, only 11 patients met the criteria of schizotypal personality. We found excellent concordance for paranoid personality and depression between the two instruments of diagnosis. However, we did not find cases with either antisocial or avoidant personality. We also found a significant link between poor control of epilepsy and high scores in both paranoia and psychopathic deviate. CONCLUSIONS: In comparison with the DSM-IV criteria for such personality disorders, the MMPI was oversensitive in detecting schizotypal features. However, the MMPI correctly classified the remaining personality disorders, especially depression and paranoid personality. On the basis of these results, we conclude that psychopathology is overrepresented in patients with chronic non-lesional epilepsy and that, in determined variables, this is due to the severity of the condition rather than to the type and duration of epilepsy. The approach to patients with chronic epilepsy should include neurobehavioural scales.

[The result of testing psychotic disorder patients in general hospital with Minnesota Multiphasic Personality Inventory].

OBJECTIVE: To study the psychological characteristics of patients with psychotic disorder in general hospital. METHODS: 92 male and 158 female patients with psychotic disorder were tested with Minnesota multiphasic personality inventory (MMPI). They consist of 215 cases with neurosis (hypochondriasis, depression, anxiety, obsessive-compulsive disorder, hysteria, neurasthenia); 4 cases with schizoaffective disorder; 3 cases with manic-depressive insanity. 5 cases with schizophrenia and 23 cases of somatoform disease with affective disorder. RESULTS: The scores of F, K, Hs, D, Hy, Pd, Pa, Pt and Si scales in the patients were significantly higher than those in normal controls. The scores of Mf were significantly higher in the male han those in the female patients and the scores of F lower in the male than those in the female patients. CONCLUSIONS: The psychotic disorders as well as seen in patients in general hospital are hypochondriasis and somatoform disorder, and depression of the female.

Minnesota Multiphasic Personality Inventory correlates of panic disorder with agoraphobia: changes with treatment.

Forty-seven patients meeting DSM-III-R criteria for panic disorder with agoraphobia (PAG) were assessed by the Minnesota Multiphasic Personality Inventory (MMPI) at baseline and after 8 weeks of treatment with imipramine, clomipramine and placebo. At pre-treatment patients had higher MMPI scores than the local normative data, the highest scores being for depression, hypochondria and hysteria. At week 8 the scores of most MMPI scales were significantly reduced. In addition, patients who showed clinical improvement had pre- and post-treatment scores lower than the unimproved patients. The results suggest that the abnormal MMPI profile found in PAG patients reflects the clinical state and that personality pathology relates to treatment outcome. The reduction in MMPI scores was associated with response to active treatment. We conclude that therapeutic interventions that successfully reduce PAG symptoms also modify personality scores.

The Minnesota Multiphasic Personality Inventory (MMPI) Hysteria (Hy) scale: scoring bodily concern and psychological denial subscales in chronic back pain patients.

Chronic back pain patients were compared to two nonpain comparison groups on Minnesota Multiphasic Personality Inventory (MMPI) Hysteria (Hy) scores and scores on two Hy subscales: Bodily Concern and Psychological Denial. Pain subjects had significantly higher scores on the Bodily Concern Subscale and lower scores on the Psychological Denial Subscale than nonpain subjects with similar elevated Hy scores. However, pain subjects had Psychological Denial scores similar to those of subjects with normal MMPI profiles, despite significantly higher Hy scores. These findings are interpreted to support the hypothesis that, among pain patients, Hy elevations are partially accounted for by the endorsement of a disproportionate number of Bodily Concern items. Finally, within pain patients, scores on the Bodily Concern subscale were significantly related to more indices of pain duration and severity than were scores on the Psychological Denial subscale. The potential clinical utility of scoring these subscales is discussed.

Lumbar disc herniations: the predictive value of the Health Attribution Test (HAT) and the Minnesota Multiphasic Personality Inventory (MMPI).

Ninety-one patients who were treated for lumbar disc herniation with chymopapain chemonucleolysis were evaluated preoperatively by means of the Health Attribution Test (HAT) and the Minnesota Multiphasic Personality Inventory (MMPI). There were 54 good, 10 fair, and 27 poor results after chemo-nucleolysis. Nineteen patients subsequently underwent lumbar laminectomy and discectomy and the ultimate outcome for the entire series including these laminectomy patients was 66 good, 10 fair, and 15 poor results. The fair/poor chemonucleolysis outcome patients scored significantly lower than did the good outcome patients on the HAT Powerful Others and significantly higher on the Chance scale. Patients with fair or poor outcomes after chemonucleolysis only scored significantly higher on the Hypochondriasis, Hysteria, Psychopathic Deviate, Paranoia, and Hypomania scales in preoperative MMPI testing. Good versus fair/poor ultimate outcome patients differed significantly on preoperative MMPI Hypochondriasis, Hysteria, Psychopathic Deviate, Paranoia, Psychasthenia, Schizophrenia, Hypomania, and Social Introversion scales. These groups also differed significantly on preoperative HAT Internal and Chance scales. Further analyses found the MMPI to be a slightly better predictor of chemonucleolysis outcome and much better predictor of ultimate outcome than the HAT.

Analysis of Minnesota Multiphasic Personality Inventory-2 profiles of prospective anonymous oocyte donors in relation to the outcome of the donor selection process.

OBJECTIVE: To examine the scores of prospective anonymous oocyte donors on the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) in four outcome groups. DESIGN: Chart review. SETTING: Academic medical center. PATIENT(S): One hundred fifty prospective anonymous oocyte donors who underwent a preliminary screening and a 1-hour structured psychological interview and who completed the MMPI-2. INTERVENTION(S): Psychological evaluation prior to donation. MAIN OUTCOME MEASURE(S): Scores on the MMPI-2 and outcomes of the donor selection process. RESULT(S): Seventy (47%) women were accepted as donors and completed one donation cycle; 30 (20%) were accepted as donors but did not donate because of medical reasons or relocation; 18 (12%) were accepted as donors but were noncompliant; and 32 (21%) were rejected as donors because of psychological concerns. Statistically significant differences were found between outcome groups on scales F, K, 1, 2, 7, 8, and 0. Although these differences were statistically significant, all group subscale mean scores were in the average to low-average range and differences between group means were small. CONCLUSION(S): The MMPI-2 differentiates between prospective donor outcome groups, but psychologists need to interpret the results of the MMPI-2 carefully in the context of clinical interview information.
