Problem description: Our research concerns psychometric diagnoses basing on the Minnesota Multiphasic Personality Inventory (MMPI) test [1, 3, 4]. The goal of MMPI test is to count the personality–psychometric dimensions which help in differential diagnosis of given person and to assess psychotherapy results. Finally given person should be assigned to one (or two if given case is placed on a bo...

An empirical typology of problem drinker-drivers based on the Minnesota Multiphasic Personality Inventory (MMPI) was evaluated. Relationships were demonstrated between this typology and several kinds of external criteria: alcoholism symptoms, reasons for drinking, treatment participation and outcome and medical complications. Indicators of typological validity were further evaluated in the cont...

The authors present a didactic illustration of how item response theory (IRT) can be used to separate measurement bias from true group differences on homogeneous and heterogeneous scales. Several bias detection methods are illustrated with 12 unidimensional Minnesota Multiphasic Personality Inventory (MMPI) factor scales (Waller, 1999) and the 13 multidimensional MMPI validity and clinical scal...

The present study examined whether therapist access to the Minnesota Multiphasic Personality Inventory (MMPI-2) predicted favorable treatment outcome, above and beyond other assessment measures. A manipulated assessment design was used, in which patients were randomly assigned either to a group in which therapists had access to their MMPI-2 data or to a group without therapist access to such in...

We attempted to cross-validate findings from a previous study (Elhai, Gold, Sellers, & Dorfman, in press) using a clinical sample of combat-related war veterans to distinguish genuine from malingered posttraumatic stress disorder (PTSD) on the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). The MMPI-2 scores of 124 male combat war veterans at the PTSD outpatient treatment progra...

Several Minnesota Multiphasic Personality Inventory–2 Personality Psychopathology Five (PSY-5) scales and facets showed small to medium levels of predictive validity in identifying law enforcement officer applicants who would later be forced to leave their agencies (n = 436 still employed, n = 164 forced to leave agency). The PSY-5 measures were moderately to strongly associated with measures o...

The ability of the MMPI-168 to estimate full-scale high-point code types was evaluated in 772 men inpatient alcoholics. Although concordance of code types was found to be 35% across the entire sample, concordance rates of specific codes varied from 78% for the 2-4/4-2 type to only 15% for the 7-8/8-7 type. The MMPI-168 also underestimated the frequency of many full-scale code types. Overall, th...

Computerized adaptive testing in personality assessment can improve efficiency by significantly reducing the number of items administered to answer an assessment question. Two approaches have been explored for adaptive testing in computerized personality assessment: item response theory and the countdown method. In this article, the authors review the literature on each and report the results o...

Due to the possibility of negatively impacting their license to practice, professionals presenting for an intensive fitness for duty multidisciplinary evaluation might have a motivation to minimize emotional difficulties in a psychological evaluation. This study examines the incidence of "fake-good" Minnesota Multiphasic Personality Inventory-2 (MMPI-2) profiles in those being evaluated and cha...

The purpose of this study was to investigate the extent to which the depression scales of the Minnesota Multiphasic Personality Inventory-Adolescents (MMPI-A) and the Millon Adolescent Clinical Inventory (MACI) show convergence with a sample of 252 adolescents from an inpatient psychiatric facility. Both inventories were administered as part of the intake process. Pearson correlations were comp...
