MMPI experimental scale correlates of the MAACL--R with male alcoholics.

Concurrent and discriminative validity of the MAACL--R scales were studied by means of correlations with selected MMPI experimental scales (AR, DR, HOS, Poor Morale, and ES) for a sample of 88 male VA alcoholics. Concurrent validity of Anxiety, Depression, Hostility and PASS, and discriminative validity of the Anxiety scale were confirmed.     

MMPI differences among Mexican-American male and female psychiatric inpatients

The purpose of this study was to examine to what extent Mexican-American male and female psychiatric patients, who share similar DSM-III--R diagnoses, differ on the MMPI. Differences were found on the Infrequency, Masculinity-Femininity, and Paranoia scales, with the 39 men obtaining significantly higher scores than the 21 women. These results, while suggesting possible differences in the phenomenology of depression, also suggest that MMPI differences between Mexican-American men and women may be reflective of culturally-defined sex roles. These results, when taken within the context of Mexican-American MMPI literature, indicate that researchers should always attempt to account for "gender" when conducting cross-ethnic MMPI comparisons. The practice of grouping the MMPIs of Mexican-American men and women for comparison with other ethnic groups should be discontinued in favor of comparisons that consider the effects of gender and ethnicity.     

Racial identity and the MMPI in African American male college students

The relation of the Minnesota Multiphasic Personality Inventory (MMPI) to the Racial Identity Attitude Scale--Black, Short Form (RIAS-B) was examined among 50 African American male college students in a reanalysis of unpublished MMPI data described in R. H. Dana (1993). This permitted study of relationships between MMPI scores and specific psychological variables hypothesized to produce cultural differences among African Americans. Results indicated RIAS-B scale scores functioned as predictors of MMPI scale scores. Similar research with the MMPI-2 incorporating larger samples that more adequately represent African American heterogeneity is needed. Methodological implications of these findings for MMPI-2 research with ethnic and racial groups are discussed, emphasizing the importance of research to depathologize African American racial and cultural identity.     

Aggressive response sets and subtle-obvious MMPI scale distinctions in male offenders

The effects of aggressive and nonaggressive response sets on the MMPI subtle and obvious clinical subscales were investigated. Fifty-eight male prison inmates answered the MMPI as if they were either highly aggressive or highly nonaggressive. The clinical scales with sufficient items in each category were scored for subtle, neutral, and obvious subscales. Inmates successfully feigned aggressiveness on several of the obvious subscales (p = .0056) and one neutral scale; the subtle subscales were not significantly different across groups, consistent with previous research on this population in terms of the resistance of subtle items to these response sets.     

Comparison of two self-report instruments for assessing binge eating in bariatric surgery candidates

This study compared two self-report methods for assessing binge eating in severely obese bariatric surgery candidates. Participants were 249 gastric bypass candidates who completed the Questionnaire on Eating and Weight Patterns-Revised (QEWP-R) and the Eating Disorder Examination-Questionnaire (EDE-Q) prior to surgery. Participants were classified by binge eating status (i.e., no or recurrent binge eating) with each of the measures. The degree of agreement was examined, as well as the relationship between binge eating and measures of convergent validity. The two measures identified a similar number of patients with recurrent binge eating (i.e., at least 1 binge/week); however, overlap was modest (kappa=.26). Agreement on twice weekly binge eating was poor (kappa=.05). The QEWP-R and EDE-Q both identified clinically meaningful groups of binge eaters. The EDE-Q appeared to differentiate between non/infrequent bingers and recurrent bingers better than the QEWP-R, based on measures of convergent validity. In addition, the EDE-Q demonstrated an advantage because it identified binge eaters with elevated weight and shape overconcern. Using the self-report measures concurrently did not improve identification of binge eating in this study. More work is needed to determine the construct validity and clinical utility of these measures with gastric bypass patients.     

MMPI ratings of suicide risk.

Among past attempts to use MMPI data to predict suicidal behavior, there has been a lack of research on the ability of clinicians to identify MMPI profiles of suicidal persons. In this study, the MMPI profiles of 20 male psychiatric patients who committed suicide and the MMPI profiles of 20 male patients who did not attempt or commit suicide were presented to six clinical psychologists with expertise in MMPI interpretation. The clinicians were asked to classify each MMPI profile as coming from a patient who did or did not later commit suicide, and to rate eight variables thought to be relevant to the assessment of suicide risk. Data analysis revealed that the clinicians could not identify suicide and nonsuicide patients from their MMPI profiles. Furthermore, the ratings of the eight suicide variable did not differentiate suicide and nonsuicide patients.     

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.     

MMPI identification of nonrehabilitants among disabled veterans.

Utilized the Minnesota Multiphasic Personality Inventory (MMPI) with IQ scores and selected biographic data to identify drop-outs in a Veterans Administration vocational rehabilitation program. Subjects were 61 male disabled veterans. Data were collected at VA Hospital Richmond, Virginia, between September 1973 and September 1974. Follow-up six months after entrance into training utilized persistence in training or employment as success criteria. Multivariate analysis identified 32 of 33 successful and 25 of 28 unsuccessful subjects with p less than .001. Factor analysis of the best predictors identified MMPI Psychopathic deviate (Pd) Hypomania (Ma), and Lie (L) scales which was interpreted to be a social adjustment factor. Four other factors were identified. Results indicated the MMPI was a useful instrument in the identification of disabled veterans who were likely to experience difficulty in post-hospital vocational rehabilitation.     

MMPI screening scales for somatization disorder

44 items on the MMPI were identified which appear to correspond to some of the symptoms in nine of the 10 groups on the Perley-Guze checklist for somatization disorder (hysteria). This list was organized into two scales, one reflecting the total number of symptoms endorsed and the other the number of organ systems with at least one endorsed symptom. Full MMPIs were then obtained from 29 women with primary affective disorder and 37 women with somatization disorder as part of a follow-up study of a consecutive series of 500 psychiatric clinic patients seen at Washington University. Women with the diagnosis of somatization disorder scored significantly higher on the somatization disorder scales created from the 44 items than did women with only major depression. These new scales appeared to be slightly more effective in identifying somatization disorder than the use of the standard MMPI scales for hypochondriasis and hysteria. Further development is needed.     

MMPI profiles of women in codependency treatment.

The Minnesota Multiphasic Personality Inventory (MMPI) profiles of 73 women presenting themselves for treatment of codependency in a 10-day residential setting were examined. Results suggest a significant amount of psychopathology to be present in this population. More than 50% of these individuals produced clinically significant elevations of five or more scales, and 38% produced elevations on six or more scales.     

Assessing dissimulation and denial on the MMPI in a sample of maximum security, male inmates

Comparisons were made between three groups of maximum security inmates thought to possess varying degrees of motivation to either exaggerate or suppress psychiatric symptomatology in their Minnesota Multiphasic Personality Inventory (MMPI) self-report. A group of individuals requesting single-cell placement (the group hypothesized to be motivated to exaggerate symptomatology) were found to score significantly higher on Scale F, the F-K Index, and a number of special MMPI scales (i.e., D-O, Hy-O, Pd-O, Pa-O, Ma-O, Dissimulation Scale, total number of Obvious Items, O:S Ratio) and significantly lower on scales K, Hy-S, Ma-S, and the total number of Subtle items relative to inmates undergoing parole evaluations (denial condition) or entering group therapy (neutral condition). Differences between the parole and group therapy conditions were relatively small, with only D-O, Hy-O, and the Dissimulation Scale producing statistically significant results. These findings tend to support use of the MMPI in assessing a respondent's test-taking attitude, particularly in cases where the subject is attempting to exaggerate psychiatric symptomatology.     

Factor structure and item analysis of the yale food addiction scale in obese candidates for bariatric surgery

Converging research suggests phenomenological and neurobiological similarities between excessive food consumption and addictive behaviour in substance dependence. Recently, the Yale Food Addiction Scale (YFAS) has been proposed for the assessment of addictive eating behaviour. The German version of the YFAS was administered to obese individuals seeking bariatric surgery (N?=?96). Factor structure, internal consistency, and item statistics were analysed. Forty participants (41.70%) received a food addiction diagnosis. The one-factorial structure of the YFAS, which has been found in non-clinical samples, could be confirmed. All but three items had factor loadings >.50. Internal consistency was α?=?.82. Item analysis revealed that items related to unsuccessful attempts to cut down and consumption despite physical and emotional problems were endorsed by the majority of participants. Findings support the use of the YFAS in clinical populations, while applicability of some items differs between clinical and non-clinical samples.

MMPI Scales for measuring Eysenck's personality factors

Four new MMPI Scales were constructed to identify Eysenck's personality factors of psychoticism, extraversion, and neuroticism as well as a lie score. The scales showed good construct validities against the Eysenck Personality Questionnaire and the Friedman Overlap Scales developed from items in the MMPI. The study also supported the construct validity of the Friedman overlap scales.
