Comparison of the Mexican and American norms of the MMPI-2.

This article presents the results of the norms for the Mexican general population in comparison with the North American normative population. This study addresses psychopathology from the point of view in which emic and etic traditions are combined. The Mexican sample includes 1744 adults from different regions of the country. Means and standard deviations were calculated and compared with the North-American normative sample. Cronbach alpha coefficients also were obtained. The greatest differences observed were in the scales L (lies) and 5 (masculinity-femininity), which indicates that the greater distinctions between both populations are with respect to test-taking attitude in taking the test, which may be due to cultural factors. In comparison to the American norms, the Mexican population does not show psychopathology on the MMPI-2 scales.

Dynamics of personality test responses: the empiricist's manifesto revisited.

This article revisits the classic empirical manifesto written by Meehl in 1945, and examines subsequent developments in structured personality assessment. The current status of personality assessment from an empirical-scale-development perspective is presented, with examples drawn from recent work on the MMPI-2. Meehl's heuristic defense of empirically based personality-scale construction was reexamined and the lasting influences of these views were highlighted. Meehl's early conceptualization of the relative unimportance of item content in personality-test construction and several alternative views were summarized, and Meehl's modified position was described. The role that test-taking attitudes can play in personality assessment was discussed in the 1945 article, and Meehl's views on the need for appraisal of invalidating conditions have been reaffirmed in contemporary test development. Finally, the so-called "dynamics" of a structured personality item response were discussed from a contemporary perspective, and some recent research was included to illustrate the continued importance of anchoring test interpretation in empirical correlates.

Revising psychological tests: lessons learned from the revision of the MMPI.

Some types of psychological tests become dated and require more frequent and more extensive revision than others. Because of the formidable effort that is required in a test revision, the goals and scope of the revision need to be carefully staked out before a revision is undertaken. The revision team needs to develop a generally agreed-upon guiding philosophy for the test revision in the beginning of the project and incorporate broad input into the changes that are likely to be required. Factors important to consider in a test revision are discussed, and the parameters of personality test revision illustrated from the extensive program to revise the Minnesota Multiphasic Personality Inventory (MMPI) are included. Recommendations for gauging acceptance of the revision are suggested along with steps that revisers and publishers might take to make a test revision both more research based and more acceptable to test users.

Utility of the MMPI-2 in assessing gender dysphoric patients.

We compared MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) profiles of 2 groups of adult biological men requesting sex reassignment surgery; 1 group was diagnosed with Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-III-R]; American Psychiatric Association, 1987) transsexualism and the other with gender identity disorder of adolescence and adulthood, nontranssexual type (GIDAANT). Although the mean profiles for the transsexual group did not demonstrate any psychopathology, the GIDAANT group showed moderate psychopathology. A cluster analysis indicated that 85% of the transsexual group showed low psychopathology and 47% of the GIDAANT group showed severe psychopathology. Neither the MMPI-2 results nor the DSM-III-R clinical evaluation support the conclusion of many authors that transsexualism is associated with severe personality disorder; rather, the data indicate that transsexualism and other gender identity disorders without persistent wish for sex reassignment differ significantly in degree of psychopathology.

Effect of altered instructions on the MMPI-2 profiles of college students who are not motivated to distort their responses.

Research has shown that when the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) is administered with instructions designed to make people aware of the validity indexes and when people are encouraged to respond honestly rather than invalidate the test through defensiveness, their scores on validity scales suggest a more candid responding. Before such modified administration procedures can be broadly used to increase the validity of the MMPI (Hathaway & McKinley, 1943) profiles, it is necessary to have more information about the effect of the altered instructions on test performance of people in general. This study involved administering the MMPI-2 to a group of 218 "normals" (college students) with instructions that differed from traditional instructions. Specifically, the test instructions were altered to explain more about the test and the presence of validity scales to apprise participants that disingenuous responding can be detected. The responses of college students taking the test under altered instructions were compared with those of a similar sample of 150 college students who took the test under standard instructions. Although under altered conditions there was a statistically significant tendency for measures assessing defensiveness (L, K, and S) to be lower for some participants (women but not men), the differences were trivial. Modified instructions made little practical difference in test performance when people who were not motivated to deceive on the test were informed of the presence of validity checks on the test.

Validity and utility of computer-based test interpretation.

Computers have been important to applied psychology since their introduction, and the application of computerized methods has expanded in recent decades. The application of computerized methods has broadened in both scope and depth. This article explores the most recent uses of computer-based assessment methods and examines their validity. The comparability between computer-administered tests and their pencil-and-paper counterparts is discussed. Basic decision making in psychiatric screening, personality assessment, neuropsychology, and personnel psychology is also investigated. Studies on the accuracy of computerized narrative reports in personality assessment and psychiatric screening are then summarized. Research thus far appears to indicate that computer-generated reports should be viewed as valuable adjuncts to, rather than substitutes for, clinical judgment. Additional studies are needed to support broadened computer-based test usage.

MMPI-2 with Mexican psychiatric inpatients: basic and content scales.

This paper presents the results of a study of the Mexican Spanish version of the MMPI-2 with a clinical sample of 233 patients who were diagnosed as having psychological disturbances or personality disorders, according to DSM-III R criteria. Inpatient scores were obtained from four psychiatric hospitals, located in Mexico City. The scores of the patients were compared with those of Mexican college students, which is the largest Mexican normative sample collected to date, consisting of 813 men and 1,137 women. Results of this study show that the MMPI-2 can accurately differentiate between normal and non-normal groups in Mexican populations and demonstrate that the inventory maintains its construct validity in this clinical sample.

Personality: individual differences and clinical assessment.

Research in clinical personality assessment continues to be produced at a high rate. The MMPI/MMPI-2 remains the most popular instrument for both clinical application and psychopathology research. Two other clinical personality instruments, the Rorschach and TAT, continue to find a place in research and clinical assessment. Some new instruments have surfaced recently to deal with areas, such as personality disorders, that have been considered inadequately addressed. There is a growing recognition that the Five-Factor Model is too superficial for clinical assessment that requires more refined and broadened patient information. Clinical personality assessment has successfully survived a number of past challenges. The newest challenge stems from the health-care revolution, in which managed-care providers are reluctant to pay for assessment because of shrinking funds. Psychologists need to develop models for incorporating assessment information into the treatment process. The future is likely to see more extensive research and theoretical development in this endeavor.

Psychological assessment of airline pilot applicants with the MMPI-2.

Psychological tests like the Minnesota Multiphasic Personality Inventory (MMPI) have been used widely to assess personality characteristics and appraise potential mental health problems of individuals applying for responsible positions. This study had three major goals: First, these data allowed for an evaluation of the effects of the new norms for the traditional validity and clinical scale scores of the MMPI-2 in an employment selection program. Second, the effects that test defensiveness had on the MMPI-2 scores of a group of individuals, airline pilot applicants who were taking the test in a preemployment context, were evaluated. Third, useful descriptive information was provided on the performance of airline pilot applicants on MMPI-2 scales to give interpretive guidelines for using the MMPI-2 in psychological screening. A sample of 437 airline pilot applicants seeking employment as airline flight crew members was administered the MMPI-2. Results of the study showed that the MMPI-2 norms were more appropriate for characterizing pilot applicants than were the original MMPI norms, which tended to overpathologize test takers. The effects of defensiveness on MMPI-2 profiles were found to be pronounced. Interpretive guidelines for using the MMPI-2 in personnel screening were proposed.

Development of MMPI-A alcohol/drug problem scales.

The present study introduces two new scales for the assessment of alcohol and other drug problems developed from the new Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A), including the rationally constructed Alcohol/Drug Problems Acknowledgement Scale (ACK) and the empirically-derived Alcohol/Drug Problems Proneness Scale (PRO). Validity of these scales is examined by comparing scores from a sample of adolescents hospitalized for alcohol and other drug problems with a normative sample of adolescents and with a sample of adolescents in psychiatric inpatient treatment. Results suggest that ACK and PRO show promise in the detection and description of alcohol and other drug problems in young people. Comparisons of ACK and PRO with other adult-derived MMPI-2 scales (e.g., the MacAndrew Alcoholism Scale, MAC-R and the Addiction Potential Scale) provide support for the practice of developing age-appropriate instruments for adolescents.

A factor analytic study of coping styles and the MMPI-2 content scales.

The relationships among coping styles and psychopathology were examined with the MMPI-2 content scales and a reliable and valid coping measure--the Coping Inventory For Stressful Situations (CISS). Subjects were 167 higher-functioning normal adult males. The results are consistent with previous research that employed the CISS; a strong positive association was found between emotion-oriented coping strategies and various measures of psychopathology. Task-oriented coping strategies were found to be unrelated to these measures. Results are discussed in the context of a potential model for understanding the various relationships among coping styles and psychopathology.

New measures for assessing alcohol and drug abuse with the MMPI-2: The APS and AAS.

We introduce two new scales for assessing substance abuse problems with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2): the Addiction Potential Scale (APS), a 39-item empirically derived scale, developed by contrasting the responses of a large residential substance abuse sample with responses from both normative and psychiatric control groups; and the Addiction Acknowledgement Scale (AAS), a 13-item face-valid scale, constructed rationally and with attention to internal consistency. Both new scales are shown to discriminate well between groups and substantially better than other selected substance abuse scales. Covariation between the scales and joint effectiveness are examined. Finally, limitations for their practical utility are expressed, and considerations for future research are identified.

A cross-validation of MMPI-2 substance abuse scales.

We evaluated the efficacy of the Addiction Potential Scale (APS) and the Addiction Acknowledgement Scale (AAS), two new scales designed to assess substance abuse problems with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), in samples from settings different from those used in their development. Results replicate earlier findings that both scales discriminate between psychiatric and substance abuse samples and do so more effectively than other substance abuse scales designed for use with the MMPI and carried over to the MMPI-2. Results also suggest that APS may be more resistant than AAS to response distortion.

Personality and aging: a study of the MMPI-2 among older men.

We examined whether separate norms for older men are necessary for the revised Minnesota Multiphasic Personality Inventory (MMPI-2). Scores from 1,459 men in the Normative Aging Study (NAS) (age: M = 61.27, SD = 8.37) were contrasted with those from 1,138 men from the MMPI Restandardization Study (age: M = 41.71, SD = 15.32). Results showed that scores on the MMPI-2 validity, clinical, and content scales for the NAS men were highly similar to those from the MMPI-2 Restandardization sample. There were also few differences between the two groups at the item level. Within-sample analyses revealed some differences between age groups. However, the magnitudes of these differences were small and may represent the single or combined effects of cohort factors and age-related changes in physical health status rather than age-related changes in psychopathology per se. We concluded that special, age-related norms for the MMPI-2 are not needed for older men.

Assessment of coping: an empirical illustration of the problem of inapplicable items.

The prevalence and effects of inapplicable items on the Ways of Coping Questionnaire (WOC) were studied. Three hundred seventy-six college students completed the WOC twice, referring to both heterogeneous (i.e., different types of) and homogeneous (the same) stressors. In addition to the standard procedure for administering this questionnaire, subjects were asked to identify items that were inapplicable to the stressors with which they were coping. Item inapplicability ranged from 2.1% to 83.9%, with a mean of 21.5% inapplicability across all WOC items. Application of a correction for item inapplicability demonstrated that situational effects are confounded by this phenomenon and may not hold up when the correction is applied. Implications of these findings include the possibility that previous research has over- or misidentified situational effects on coping.

Couples in marital distress: a study of personality factors as measured by the MMPI-2.

This study examines the relationship between Minnesota Multiphasic Personality Inventory-2 (MMPI-2) measured personality characteristics and marital distress and provides empirical validation for using the MMPI-2 with a marital therapy population. Studied were 150 couples in marital therapy and 841 normal couples who participated in the MMPI-2 restandardization study. The MMPI-2, a biographical form, a partner rating form, and the Dyadic Adjustment Scale (DAS) were administered to all couples. The marital counseling group resembled previous marital counseling samples studied with the MMPI and scored significantly higher than the normative sample on several MMPI-2 scales. Relationships between the DAS and MMPI-2 clinical and content scale scores are reported. The Psychopathic Deviate (Pd) clinical scale and Family Problems (FAM) content scale were the most powerful group discriminators and strongest correlates of the DAS; their use as indices of marital distress is tested. The meaning of Pd as an index in assessing personality factors in marital distress is explored.

MMPI-2 profiles of women at risk for child abuse.

This study addresses the utility of the MMPI-2 in assessing personality characteristics of women who have a high potential for abusing their children. A sample of 154 women was identified on the basis of demographic characteristics as high risk for child abuse and other care-taking problems. They were evaluated (with the MMPI-2-AX form) during their pregnancy and are being followed up as part of the evaluation of a prevention/intervention program. This preliminary study compares the MMPI-2 personality characteristics of 146 of these women with several control samples: 1,462 women from the MMPI restandardization sample, 466 low education women from the restandardization sample, 84 pregnant women from the restandardization sample, and 167 women military recruits who are about the same age as the experimental group. The results show that, on the MMPI-2 clinical scales, women from the high-risk sample closely resemble child-abusing parents described in the previous MMPI literature. Moreover, these women differed significantly from all of the comparison groups on a number of MMPI-2 clinical and content scales. The clinical implications of these differences are discussed.
