MMPI Response-Set Characteristics Among Adolescents

This study examined the Minnesota Multiphasic Personality Inventory (MPPI) profile characteristics for five different response sets in adolescent populations employing adolescent MMPI norms. In general, findings for "all-true" and "all-false" adolescent profiles were highly similar in shape and elevation to those reported in the adult literature (Graham, 1977; Lachar, 1974), whereas random profiles on adolescent norms differed substantially from adult-norm random profiles in shape but not elevation. The characteristics of "fake good" or "fake bad" response sets were investigated by the use of adolescent subjects in two settings. Ninety-four public high-school students were administered the MMPI with standard and "fake bad" instructions, and 24 adolescents in inpatient psychiatric treatment were administered the MMPI under standard and "fake good" instructions. The MMPI profiles generated by special instructional sets were analyzed in relation to the subject's age, sex, race, and actual MMPI profile features. Findings indicated that although sex and race effects were evident in normal adolescents' attempts to simulate psychopathology on the MMPI, teenagers generally produce profiles containing grossly exaggerated symptom patterns that are relatively easy to detect as invalid. In contrast, it was found that a substantial number of psychiatrically disturbed adolescents may effectively simulate normal profiles and that effectiveness in these attempts was related to greater age and lower actual MMPI T-score values on the Hs and Hy scales.

Partial Confirmatory Factor Analysis: Described and Illustrated on the NEO–PI–R

Short forms of the MMPI have been criticized due to their inability to adequately reproduce the profiles of the full length version of the MMPI Oftentimes these short forms are used with subject populations dissimilar to the population upon which the short form was originally standardized. This study evaluates the effect of using local norms with one of these short forms (the FAM) upon the concordance rates of profile code-types with the original full-length MMPI profile. Single point, first 2 high-point and first 3 high-point code-types were found to have higher concordance rates when using local norms. Use of local norms for short MMPI forms may compensate, in part, for information lost in the shortening.

Body Language of Women and Judgments of Vulnerability to Sexual Assault

The present study experimentally examined the effects of body language on judgments of vulnerability to sexual assault by strangers. Four features of body language (stride length, weight shift, body-limb movement, and foot movement) were manipulated to create 2 typical victim profiles and 1 typical nonvictim profile. Short videotapes of 3 adult female models walking alone in each of the 3 body language profiles were filmed. Forty-one college students and 33 police officers individually viewed 3 videotapes (each showing a different model and a different body language profile) and made judgments for each about the woman's confidence level and vulnerability to sexual assault. As predicted, women in the 2 victim profiles were judged to be significantly more vulnerable to sexual assault and significantly less confident than women in the nonvictim profile. Implications and suggestions for future research are discussed.     

The MMPI-2: A Contemporary Normative Study of Midwestern Family Medicine Outpatients

For more than 60 years it has been known that profiles from the Minnesota Multiphasic Personality Inventory (MMPI), obtained from medical patients, are elevated when scores are plotted using general population norms. These elevations have been most apparent on the neurotic triad (NTd), the first 3 clinical scales on the MMPI profile. More than 45 years have passed since a nonreferred, normative sample of MMPIs was established from 50,000 consecutive medical outpatients. We present comparable but contemporary normative data for the revised MMPI (MMPI-2) based on a nonreferred sample of 1,243 family medicine outpatients (590 women; 653 men). As true for the original MMPI, contemporary medical outpatients have profiles that are significantly different, clinically and statistically, from the general population norms for the MMPI-2. This is particularly evident in elevations on the NTd. New normative tables of uniform medical T (UMT) scores were developed following the procedures used to create the uniform T scores for the MMPI-2. Measures of internal consistency are reported; test-retest reliability was established over a mean of 3.7 weeks, and results characterizing the stability of the validity and clinical scales are presented.     

Original Adult MMPI Norms in Normal Samples: A Review With Implications for Future Developments

Among the most consistent criticisms of the Minnesota Multiphasic Personality inventory (MMPI) has been the adequacy of the standardly employed adult norms. Recent work at the Mayo Foundation has provided revised adult norms, and the Restandardization Project at the University of Minnesota Press will soon provide an additional norm set. This article reviews findings from 21 studies of normal adults, comparing obtained MMPI scale values to the standard norms. These comparisons indicate that the traditional adult norms may have contained detectable degrees of bias since their publication, and that consistent patterns of differences from standard MMPI norms can be found in independent studies published as early as 1949. Two separate considerations impact on the development of new adult norms: the research need for adult norms which accurately reflect the response patterns of the general population and the clinical need to evaluate individual psychiatric patients on norms that produce codetypes related to an empirical literature spanning more than 40 years. This study notes the inherent tension between these two purposes and discusses the implications of new adult MMPI norms for research and clinical practice.     

Recent Adolescent MMPI Norms: T-Score Elevation Comparisons to Marks and Briggs

Minnesota Multiphasic Personality inventory (MMPI) norms developed by Marks and Briggs (1967/1972) have served as the standard adolescent norms used for over 10 years. Additional adolescent, norms, have recently been produced by Gottesman, Hanson, Kroeker, and Briggs (1987) and by Colligan and Offord (1989), thereby providing MMPI users with a potential choice of adolescent norms. Our study examines the effects of these adolescent norm sets on single-scale and profile elevations. In addition, we examine the ability of these norm sets to generate T-score values that would serve to discriminate accurately among adolescents in outpatient (n = 100), inpatient (n = 100), and normal (n = 100) settings. Results indicated teat the choice of adolescent norms resulted in important differences in profile elevation. Findings from the discriminant function analyses, however, indicated that these normative sets were roughly equivalent in discriminating among adolescents in the three settings.

Interpretive dilemmas created by the minnesota multiphasic personality inventory 2 (MMPI-2)

While the new MMPI-2 has the potential to provide more and better clinically relevant information than its predecessor, its introduction also creates several important problems for clinicians and researchers. In particular, the new norms and the use of uniform (rather than linear) T-scores result in the same raw scores on the two tests yielding clinical profiles that can be quite different, both qualitatively and quantitatively. These differences can result in difficulty in MMPI-2 profile interpretation when the user is relying on MMPI interpretive strategies. This paper addresses these concerns and offers some temporary remedial strategies.     

The Personality Characteristics of Anglican Clergymen and Clergywomen: The Search for Sex Differences

The aim of this study is to compare the personality profile of Anglican clergymen and clergywomen with the general population profile. Data were provided by 235 clergymen and 54 clergywomen serving in the Church in Wales who completed the short-form Eysenck Personality Questionnaire Revised. These data demonstrated that the usual sex differences found in the population as a whole were not reproduced among the clergy, since there were no significant differences between clergymen and clergywomen in terms of extraversion, neuroticism, psychoticism and the lie scale. Compared with the population norms, the two key differences were that clergymen recorded significantly lower psychoticism scores (closer to the female norms) and clergywomen recorded significantly lower neuroticism scores (closer to the male norms). The implications of these findings are discussed for the development of the ministry of men and women in the church.     

Managerial motivational profiles: Composition,antecedents, and consequences

Using a person-centered approach, we identified managers' (N = 321) motivational profiles and tested a model of the antecedents and consequences of these profiles. The profiles were based on four motivational types delineated by self-determination theory (i.e., external, introjected, identified, intrinsic). Latent profile analysis revealed six distinct motivational profiles. One of these was a self-determined profile (high identified and intrinsic motivation, moderately low introjected motivation, and low external motivation). Four other profiles combined average levels of external motivation with either very low, low, moderately low, or high internal (i.e., introjected, identified, and intrinsic) motivation. The final profile involved moderately high levels of all four motives. The antecedents of profile membership examined were perceived supervisor support and perceived organizational politics. The career-related outcomes of profile membership were work attitudes and promotability. The self-determined and high internal motivation profiles were associated with the most favorable work attitudes, followed by the moderately high motivation profile. The low internal motivation profiles were associated with the least favorable attitudes. Promotability did not differ across the profiles. With respect to the antecedents, low levels of supervisor support and high levels of politics increased the odds that a manager would exhibit profiles that were less desirable than the self-determined profile. Our findings provide initial information about managers' motivational profiles, as well as the antecedents and consequences of these profiles. Further, these results demonstrate the promise of a person-centered approach for advancing motivation research and management development.     

Comparability of Two-Point High-Point Code Patterns From Original MMPI Norms to MMPI-2 Norms for the Restandardization Sample

Using records from the 1,138 males and 1,462 females in the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) restandardization sample (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989), two-point high-point code patterns generated from the original norms were compared to the patterns that these subjects obtained from the new norms. Although some code patterns proved to be quite stable across both norms, code comparability was generally lower in this community-based sample than was true for the records from samples of psychiatric patients also reported in Butcher et al. (1989). The sources of differences between the original and the new norms were reviewed, and the implications for profile interpretation based on code patterns were pointed out. The differences arising from the use of the MMPI-2 norms are appreciable; they highlight the need for new empirical data on the correlates of coding patterns based on these norms.

Motivational Profiles Among Young Table-Tennis Players in Intensive Training Settings: A Latent Profile Transition Analysis

This study aimed to (a) identify motivational profiles among a sample of 141 young table-tennis players involved in intensive training settings; (b) examine the consistency or change of motivational profiles for the same athlete over time; and (c) investigate differences between these profiles on burnout, coping, stress, and recovery. Latent profile transition analysis revealed 2 or 3 distinct profiles that are similar for the 3 measurement occasions: self-determined profile, moderate profile, and low profile. Motivational profiles exhibited both stability and changes over time from an intraindividual perspective. Athletes from the self-determined profile were characterized by the best psychological adjustment.     

Comparison of two methods of MMPI-2 profile classification

The present study investigated the extent of agreement of the highest scale method and the best-fit method in matching MMPI-2 profiles to database code-type profiles and considered profile characteristics that may relate to agreement or disagreement of code-type matches by these two methods. A sample of 519 MMPI-2 profiles that had been classified into database profile code types by these two methods was studied. Resulting code-type matches were classified into three groups: identical (30%), similar (39%), and different (31%), and the profile characteristics of profile elevation, dispersion, and profile code-type definition were studied. Profile code-type definition was significantly different across the three groups with identical and similar match profile groups showing greater profile code-type definition and the different group consisting of profiles that were less well-defined.     

The classification accuracy of the Minnesota Multiphasic Personality Inventory-Adolescent: effects of modifying the normative sample

Numerous studies have reported that the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) produces a high frequency of within-normal-limits basic scale profiles for adolescents with significant clinical pathology (e.g., Archer, 2005). The current study builds on the observation that the MMPI-A normative sample included participants who reported a recent history of referral for counseling or therapy services. The 193 adolescents who reported referral for counseling were removed from the normative sample and uniform T-score values were recalculated for basic clinical scale raw scores. The frequency of within-normal-limits profiles was only marginally reduced by using the revised MMPI-A norms. Furthermore, the overall hit rate, positive predictive power, and sensitivity were only slightly improved by removing normative participants referred for counseling and basing norms on the remaining 1,427 adolescents.     

Profiles of successful aging in middle-aged and older adult married couples

The study identified coupled profiles of successful aging in middle-aged (n = 139; wives, M = 43.8 years old; husbands, M = 45.6 years old) and older adult married couples (n = 148; wives, M = 62.0 years old; husbands, M = 64.4 years old). Latent profile analysis was applied to variables reflecting the domains of cognition, physical health, personality, and social support. A 2-profile solution and a 4-profile solution were interpreted. Both solutions indicated that a large group of couples scored favorably across domains of successful aging. A small group of largely middle-aged couples who were experiencing extreme marital distress was identified. Unevenness across domains was identified, in that some groups involved a disassociation between marital satisfaction and health outcomes. Spouses were substantially similar in the pattern of their profile of aging. Older adults were not always associated with less favorable profiles. Profiles of successful aging did discriminate on external measures of well-being. The results point to the value of a multidimensional notion of successful aging in couples across the life span.     

Representing young and older adult faces: Shared or age-specific prototypes?

ABSTRACT

Young adults recognize young adult faces more accurately than older adult faces and are more sensitive to how individual young faces deviate from a norm/prototype. Here we used an adaptation paradigm to examine whether young and older adult faces are represented by separable norms and the extent to which the coding dimensions for these two categories overlap. In Experiment 1, following adaptation to oppositely distorted young and older faces (e.g., expanded young and compressed older faces), adults’ normality judgments simultaneously shifted in opposite directions for the two face categories, providing evidence for separable norms. In Experiment 2, participants were adapted to distorted faces from a single age category (e.g., compressed young); aftereffects transferred across face age but were larger for the face age that matched adaptation. Collectively, these results provide evidence that young and older faces are processed with regard to separable norms that share some underlying coding dimensions.
