MMPI configural interpretation as applied to posttraumatic stress disorder in Vietnam veterans.

This study investigated the systems of Minnesota Multiphasic Personality Inventory (MMPI) configural interpretation of Skinner and Jackson (1978) and Kunce (1979) with Vietnam veterans with posttraumatic stress disorder (PTSD). MMPI profiles of four groups differing in combat exposure were compared on four MMPI configural variables from Kunce (1979) and Skinner and Jackson (1978). The four groups were (a) PTSD sufferers, (b) Vietnam combat veterans without PTSD, (c) Vietnam noncombat veterans, and (d) Vietnam era veterans. All groups were further divided into hospitalized versus nonhospitalized subgroups. Dependent variables were Skinner and Jackson's (a) sociopathic modal profile, (b) neurotic profile, (c) psychotic profile, and (d) Kunce's emotional expression (enthusiastic-reserved) dimension. Results indicated that hospitalized PTSD subjects had significantly higher scores on Skinner and Jackson's neurotic profile; both hospitalized and nonhospitalized PTSD subjects had higher scores on the psychotic profile and were more "reserved" on Kunce's emotional expression dimension. Results were interpreted in terms of configural MMPI interpretation systems and the adjustment of Vietnam veterans with PTSD. PTSD was viewed as exhibiting cognitive, somatic, and affective features.

Estimation of MCMI DSM-III axis II constructs from MMPI scales and subscales.

Wiggins, Harris and Lingoes, and Serkownek Minnesota Multiphasic Personality Inventory (MMPI) scores were used to predict Millon Clinical Multiaxial Inventory (MCMI) scores in a 100-patient sample. Equations from the first sample were cross-validated on a sample of 212 inmate subjects. We conclude that scores on 19 of the 20 MCMI scales can be successfully predicted by the Wiggins, Harris and Lingoes, and Serkownek subscales of the MMPI. In further cross-validation, the equations were used to predict the Morey, Waugh, and Blashfield MMPI composites for the prison sample, again with strongly positive results. The results appear quite promising for the estimation of personality disorder constructs from MMPI scales and subscales.

Relationships between physical findings (GPE-78) and psychological profiles (MMPI-2) in patients with long-lasting musculoskeletal pain.

The purpose of the study was to evaluate possible relationships between physical findings, as measured with the Global Physiotherapeutic Examination (GPE-78), and psychological characteristics, as measured with the revised Minnesota Multiphasic Personality Inventory (MMPI-2), in three groups of patients with long-lasting musculoskeletal pain. A total of 177 patients (114 women, 63 men), sick-listed owing to long-lasting musculoskeletal pain, were studied. The sample was subcategorized on the basis of pain localization, as marked on a pain drawing: group 1 = pain above a horizontal line in the thoracic-lumbar region (n = 24); group 2 = pain below the line (n = 48); group 3 = pain both above and below the line (n = 105). The GPE-78 consists of 78 standardized tests yielding quantitative information within five bodily domains: Posture, Movement, Muscle, Skin, and Respiration. Significant correlations were obtained between the GPE-78 and the MMPI-2 with regard to somatization, somatic concern, and depression. Patients with localized pain (groups 1 and 2) had few correlations between bodily findings and psychological problems compared with many inpatients with generalized pain (group 3). Women showed correlations between the domains Posture, Movement, and Muscle and psychological problems, whereas men showed correlations with Movement, Skin and Respiration. A psychosomatic MMPI-2 "V-profile" was present in groups 1 and 3. Women showed significantly higher scores than men. The relationships found between GPE-78 and MMPI-2 measures were significant, but findings differed depending on pain localization and sex. Patients with generalized pain had significantly more physical and psychological aberrations than patients with more localized pain.

Iron status and depression in premenopausal women: an MMPI study. Minnesota Multiphasic Personality Inventory.

To test the hypothesis that low iron status or other nutritional deficiencies are associated with symptoms of depression in premenopausal women, the authors related blood indices of iron status to scores on the Minnesota Multiphasic Personality Inventory (MMPI) and responses to a mood adjective checklist. Participants recruited locally provided fasting blood samples and completed the MMPI during the follicular phase of the menstrual cycle. Of 365 apparently healthy participants, 4% had hemoglobin < 120 g/L, 6% had transferrin saturation < 16%, 20% had ferritin < 12 micrograms/L, and 8% had clinically elevated scores (T > or = 70) on the Depression scale of the MMPI. The frequency of elevated MMPI Depression scores was unrelated to the frequency of low hemoglobin, transferrin saturation, or ferritin. The results do not support the hypothesis that low iron status contributes to symptoms of depression in women.

Prediction of treatment outcome from clinically derived MMPI clusters in rehabilitation for chronic low back pain.

OBJECTIVE: The aim of this study was to assess the ability of specific and clinically relevant Minnesota Multiphasic Personality Inventory (MMPI) profile types to predict outcomes in a structured interdisciplinary pain-management program for patients with low back pain. DESIGN: Subjects were divided into clusters representing MMPI profiles yielding similar clinical interpretation. Analyses of variance and chi-square testing assessed the effect of cluster group on a variety of outcome measures at pretreatment, posttreatment, and 6- to 66-month follow-up. Fisher's Least Significant Difference Test assessed the significance of differences between pairs of cluster groups. SETTING: A university-based comprehensive interdisciplinary pain-management program serving both inpatients and outpatients. PATIENTS: 122 subjects with chronic low back pain who completed the program, provided follow-up data, and fit into the definition of one of seven clusters. MAJOR OUTCOME MEASURES: Self-reports of subjective pain intensity, pain-related medication intake, and activity level at pretreatment, posttreatment, and follow-up; employment status at pretreatment and follow-up. RESULTS: Cluster groups did not differ significantly at any time on activity level and medication intake and differed on employment status only at pretreatment. There was a significant (p < 0.05) effect of cluster group on subjective pain intensity, but only two pairwise group comparisons were significant: subjects with a normal MMPI profile and those with no elevations except T = 71-80 on Hypochondriasis and Hysteria reported less pain at follow-up than did subjects with extreme elevations (T > 80) on both Hypochondriasis and Hysteria. CONCLUSION: Even when subjects with chronic pain are divided into cluster groups associated with highly similar clinical interpretations, the MMPI for the most part fails to predict self-reported outcomes in an interdisciplinary pain-management program.

MMPI changes in briefly hospitalized non-narcotic drug users.

The Minnesota Multiphasic Personality Inventory (MMPI) was administered to 66 non-narcotic drug abusers as part of an intensive study of polydrug abuse. Patients were classified into four primary drug-of-abuse groups using either stimulants, barbiturates, other sedative-hypnotics, or a combination of these drugs. It was readministered to 42 of these patients after 2 weeks' hospitalization. At admission, the group's MMPI profile was consistent with psychosis. At discharge, most of the MMPI T-scores were sharply reduced, and the groups' profile was consistent with sociopathy. The admission MMPI profiles of the four primary drug-of-abuse groups did not differ. At discharge, the stimulant group's profile remained psychotic, while the profiles of the other three groups were not psychotic. Such results raise the possibility of a toxic psychotic effect of chronic non-narcotic drug abuse. The group of stimulant abusers appeared schizophrenic, while the other groups of non-narcotic drug abusers appeared sociopathic.

MMPI correlates of menstrual distress.

The MMPI and Moos' Menstrual Distress Questionnaire (MDQ) were administered to 60 undergraduate women. Partial correlations between MMPI clinical scales and menstrual and premenstrual MDQ symptom scales were computed with intermenstrual (baseline) symptom reports and response set (Gough's F-K index) statistically controlled MMPI variables tended to correlate with some symptom scales (premenstrual pain, negative affect; menstrual behavior change) but not with others (water retention, arousal). Where correlations did occur, common MMPI scales (Sc, Hs, Hy, Pt) were involved. Results suggest that psychological factors are more closely associated with some areas of menstrual symptomatoloty than with others.

The MMPI as a predictor of outcome in low-back surgery.

Between 1965 and 1975, 103 low-back patients were rated preoperatively for general level of functioning, and each completed a Minnesota Multiphasic Personality Inventory (MMPI) test. Following surgery, patients were rated in terms of treatment effectiveness at 6 months and 1 year. The MMPI hypochondriasis and hysteria scales were moderately related to surgical success, as were the severity of initial restriction in the level of functioning and the number of operations performed during the study. However, the MMPI profiles were strikingly similar for all patients. Factors which were not predictive of surgical outcome included age, sex, duration of symptoms, number of back surgeries prior to entering this clinic, and the degree of pathologic condition discovered at operation. The failure to find a potent prediction scheme confirms that MMPI information must be used with considerable caution in treatment planning and only as an adjunct to other clinical and psychological data.

Comparisons of preoperative and postoperative MMPI data in chronic back patients.

The purpose of this study was to analyze 42 patients disabled with low-back pain in order to assess Minnesota Multiphasic Personality Index (MMPI) changes before and after surgery, the predictive value of MMPI, the results of anterior lumbar fusion in one group of severely disabled lumbar low-back pain patients. Statistical analyses were performed to compare and contrast MMPI, pain assessment, functional and occupational levels, and disability index before and after surgery. The degree of morbidity of the patients preoperatively was severe. After surgery, the majority of the patients showed improvement in their overall status. The available evidence suggests the following: Improvement in physical condition can produce improvement in psychological test scores; The preoperative MMPI is not a reliable indicator of surgical success.

The SCL-90R evaluated as an alternative to the MMPI for psychological screening of chronic low-back pain patients.

The efficacy of using the SCL-90R as an alternative measure to the MMPI in the psychological screening of chronic low-back pain (CLBP) patients was investigated. The MMPI and the SCL-90R were administered to 99 CLBP patients (63 men and 36 women) at the time of admission to a functional restoration treatment program. The SCL-90R was readministered after successful completion of the treatment program. Analyses indicated that there were significant changes on almost all SCL-90R clinical scales from pretreatment to post-treatment (P less than 0.01). Moreover, there were adequate levels of correlation between corresponding MMPI and SCL-90R scales (r ranged from 0.35 to 0.51). However, analyses of the interscale correlations of the SCL-90R indicated that it may be a single-factor instrument that assesses general psychological distress. It was suggested that the SCL-90R may be used as a screening device for psychological distress in CLBP patients, but if more detailed information about the patients' psychological condition is needed, the MMPI will be a more useful instrument.

A cluster-analytic investigation of MMPI profiles of serious male and female juvenile offenders.

OBJECTIVE: To use cluster analysis to identify psychological profiles and related mental health symptoms among male and female juvenile offenders. METHOD: Juvenile offenders (N = 141) incarcerated in the California Youth Authority completed the Minnesota Multiphasic Personality Inventory (MMPI) and the Massachusetts Youth Screening Instrument-Version 2 (MAYSI-2). RESULTS: MMPI cluster analysis revealed four distinct profiles: two for male and two for female juvenile offenders. Among males, we identified one Normative cluster with no clinically elevated scores. A second male cluster, labeled Disorganized, exhibited clinical elevations on scales 8 (Schizophrenia), 6 (Paranoia), 4 (Psychopathic Deviate), and 7 (Psychasthenia). Among females, two clinically elevated profiles emerged. One Impulsive-Antisocial cluster consisted of clinical elevations on scale 4 (Psychopathic Deviate), which has been consistently associated with delinquent and antisocial behavior. The second cluster, labeled Irritable-Isolated, produced elevations on MMPI scales 4 (Psychopathic Deviate), 8 (Schizophrenia), 6 (Paranoia), and 7 (Psychasthenia). There were no significant sex, ethnicity, or offense differences across clusters, but the clusters exhibit distinct psychiatric profiles (MMPI) and mental health symptoms (MAYSI-2). CONCLUSIONS: The findings indicate that not only do female offenders have more acute mental health symptoms and psychological disturbances than male offenders, they exhibit qualitatively distinct psychiatric profiles. Results reinforce the need for assessment of mental health symptoms for male and female juvenile offenders as well as sex-appropriate treatments.

The relationship between MMPI cluster membership and diagnostic category in headache patients.

Only one study has examined MMPI cluster profiles in the headache population. The present study expanded on this previous investigation by using a large sample size (N = 485) and a greater number of diagnostic categories. The five MMPI clusters replicated previous findings in the chronic pain literature. These MMPI cluster groups were compared to 5 diagnostic categories (migraine, cluster, post-trauma, tension, mixed). No relationship was found between cluster type and headache diagnosis. While the diagnostic groups were found to differ on measures of pain severity, sex and age, cluster groups did not. It is proposed that MMPI scale types reflect a patient's response to pain and are more likely to be the result of coping resources than headache-related personality style. Future research with additional, non-pain populations and prospective studies is suggested.

Classification of the MMPI profiles of two alcoholic groups.

Ninety-two per cent of the MMPI CODES OF 60 ALCOHOLICS IN THE Link Society and institutional groups of the present study were classified according to a mixed typological-dimensional model. The study applied reciprocal two-digit high-point codes and also five different spiked codes and two different codes which include more than two scales in predominant position. Related codes suggesting different diagnostic descriptions were, however, separated from each other. The present study also used new interpretations of some MMPI scales, detailed descriptions of the other scales and applied some critically examined measurements of certain authors. Of special interest is a detailed interpretation of codes opathic deviate) scale as a measurement of hysterical personality. The above methods gave a more exact identification of the MMPI codes than a previous study of the present author and suggest that it is possible to give a more refined description of different personality disorders in particular but also of other psycho-pathological and behavioural characteristics of the alcoholic patients in the Link Society and institutional groups. The different typal dimensions measured by the MMPI high-point codes seem to be of theoretical value but also seem to be useful for a more differentiated and adequate treatment of alcoholics. In further corroborative studies there is a need for more case history descriptions in order to correct for local departures. It is also possible that these descriptions may aid in giving a clearer identification of the codes, including scale 5, not classified in the present study.

Briquet's syndrome, hysterical personality, and the MMPI.

The authors compared the MMPI scores of 29 inpatients diagnosed by other authors as having hysterical personality and 21 outpatients diagnosed by the authors as having Briquet's syndrome. The two groups of patients differed significantly in age, on the MMPI lie scale, and on the MMPI hypochondriasis scale but not on any of the other MMPI scales. The authors discuss the implications of these findings for further defining the differences and similarities between hysterical personality and Briquet's syndrome.

Use of the MMPI-2 in the treatment of offenders.

The MMPI-2 is among the most frequently relied upon inventories for personality assessment. The test is utilized across a variety of nonforensic settings (e.g., psychiatric inpatient and outpatient) as an aid in formulating treatment plans, assessing treatment progress, and measuring treatment outcome. The MMPI-2 can also be utilized in forensic settings in a manner similar to its use in other settings, such as identifying treatment goals and evaluating treatment efficacy. Various MMPI-2 scales can identify an individual's treatment needs, reveal potential obstacles to treatment, and serve as a measure of treatment efficacy. Such information can be very helpful to the clinician in formulating or modifying a course of treatment for offenders. This article provides an overview of the use of the MMPI-2 in treatment planning and describes the relation between scores on the validity, clinical, and various supplementary scales and treatment-related issues.

MMPI-2 characteristics in a chronic pain population.

This study investigated the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) characteristics of 209 chronic pain patients in an inpatient pain treatment program. Patients completed the MMPI-2, Zung Self-Rating Depression Scale, and Oswestry Low Back Pain Disability Questionnaire. Participants in this sample were matched with comparison participants from the MMPI-2 normative sample on the demographic variables gender, age, and ethnicity. Chronic pain patients reported higher levels of general maladjustment and affective distress than did the normative control group, including more anxiety, depressive symptomatology, and somatic complaints. The MMPI-2 basic scales Hypochondriasis, Depression, and Hysteria were the most useful discriminating factors between chronic pain patients and normal controls, and the content scales Health Concerns and Depression showed significant elevations for the chronic pain group. The 1-3/3-1, 1-2/2-1, and 2-3/3-2 code types accounted for more than two thirds of all two-point classifications for the chronic pain group, and four cluster analysis types classified nearly half of all of these protocols.

Normal range MMPI-A profiles among psychiatric inpatients.

The present study examined the base rates of normal range Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) profiles in an inpatient sample and examined the differences between adolescents with apparently valid normal range profiles (all clinical scale T-scores < 60) and those with elevated profiles on prior interventions, reported internalizing and externalizing symptoms, and MMPI-A validity scale scores and other indexes of underreporting. Normal range profiles cannot be adequately explained by a less pathological history prior to hospitalization or by defensiveness. Thirty percent of male and 25% of female adolescents produced valid MMPI-A profiles in which none of the clinical scales were elevated. Both male and female adolescents with normal range profiles were generally less likely to report internalizing symptoms than those with elevated profiles, but both groups report externalizing symptoms. Neither the standard MMPI-A validity scales nor additional validity scales discriminated between profile groups. Clinicians should not assume that normal range profiles indicate an absence of problems.
