Development and validation of a method for deriving MMPI-3 scores from MMPI-2/MMPI-2-RF item responses.

The Minnesota Multiphasic Personality Inventory-3 (MMPI-3; Ben-Porath & Tellegen, 2020a) was developed to expand the content coverage of the MMPI-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011) and to update the test's norms to better represent the U.S. population.

Comparability of MMPI-3 scores from remote and in-person administrations and the impact of the COVID-19 pandemic on MMPI-3 scores.

The COVID-19 pandemic onset necessitated remote administration of psychological instruments, including the Minnesota Multiphasic Personality Inventory-3 (MMPI-3). Although previous evidence has demonstrated that MMPI scale scores are robust across administration modalities, the specific effects of remote administration on the psychometric properties of MMPI-3 scale scores must be investigated. Distinguishing psychometric differences due to administration modality from substantive changes in psychological symptoms due to the COVID-19 pandemic is also important.

Correlates of the Selection Validation Survey with Police Officer Field Performance.

In the present study, we examined performance rating correlates of the Selection Validation Survey (SVS), an informant rating form used to describe the characteristics of newly hired public safety personnel following their initial training period. We correlated SVS ratings for  = 174 police officers with aggregate scores derived from daily performance observation ratings provided by their field training officers (i.e.

The Meaning and Clinical Implications of Low MMPI-3 Self-Importance Scores.

The Minnesota Multiphasic Personality Inventory-3 (MMPI-3) includes two self-concept-oriented scales: Self-Doubt (SFD), a measure of low self-esteem, and Self-Importance (SFI), a measure of beliefs that one has special attributes and abilities. Past research has demonstrated that SFD and SFI measure related but distinct constructs. The present study focused on explicating the meaning and clinical implications of low SFI scores.

Evidence for the comparability of local and remote administrations of the MMPI-2-RF in police candidate evaluations.

In this study, we explore the effects of in-person versus remote administration and in-person versus remote proctoring on scores on the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) in the context of police candidate preemployment evaluations. To this end, we compare data gathered from candidates who completed the test under standard, in-person conditions with data from candidates who completed the test remotely with the Q-global Remote On-Screen Assessment (ROSA) system, using either in-person or remote proctoring. We find that the standard group ( = 3,311), remote administration/in-person proctoring group (ROSA-IPP; = 108), and remote administration/remote proctoring group (ROSA-RP; = 90) all produce very similar distributions of scores, with group differences in means and standard deviations no greater than two T-score points per scale.

Examining the Psychometric Equivalency of MMPI-3 Scale Scores Derived From the MMPI-3 and the MMPI-2-RF-EX.

The current study evaluated the comparability of Minnesota Multiphasic Personality Inventory-3 (MMPI-3) scale scores derived from the 335-item MMPI-3 to MMPI-3 scale scores derived from the 433-item MMPI-2 restructured form-expanded version (MMPI-2-RF-EX), an enhanced version of the MMPI-2-RF that was used to develop and validate the MMPI-3. To that end, we examined data from 192 college undergraduates who completed both the MMPI-3 and MMPI-2-RF-EX 1 week apart using a counterbalanced design. Across versions, mean T-scores and standard deviations, estimates of internal consistency, and standard error of measurement values, were highly similar, indicating no clinically meaningful differences across versions.

Analysis of the fight-ending chokes in the history of the Ultimate Fighting Championship™ mixed martial arts promotion.

Objective: Knowledge of sportive chokes is vital to the practice of Sports Medicine when providing care at mixed martial arts and submission grappling events. This is a descriptive analysis of fight-ending chokes to help provide data on the topic not previously presented.

Methods: An analysis was done on every fight-ending choke in the history of the UFC™ mixed martial arts promotion.

Development and Initial Validation of Differential Diagnostic Indices for the MMPI-2-RF.

In this article, I discuss construction of a set of weighted indices for the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) designed to provide direct guidance in three specific differential diagnostic problems. I created a calibration data set using a combined sample of mental health patients ( = 2,043). Using the MMPI-2-RF's Substantive Scales as a pool of potential predictors, I applied the lasso, a penalized regression technique, to derive three logistic regression equations differentiating three major diagnostic groups (schizophrenia, bipolar disorder, and major depressive disorder) from one another.

Construct validity of the personality inventory for ICD-11 (PiCD): Evidence from the MMPI-2-RF and CAT-PD-SF.

The Personality Inventory for ICD-11 (PiCD) was recently developed to assess the ICD-11 model of personality disorders. The purpose of this study was to examine the construct validity of the PiCD using the Minnesota Multiphasic Personality Inventory (MMPI)-2-Restructured Form (MMPI-2-RF) and the Computerized Adaptive Test of Personality Disorders Static Form (CAT-PD-SF). We administered these tests to 328 college students (150 males, 178 females).

Generalizability of statistical prediction from psychological assessment data: An investigation with the MMPI-2-RF.

In the present study, the author employed tools and principles from the domain of machine learning to investigate four questions related to the generalizability of statistical prediction in psychological assessment. First, to what extent do predictive methods common to psychology research and machine learning actually tend to predict new data points in new settings? Second, of what practical value is parsimony in applied prediction? Third, what is the most effective way to select model predictors when attempting to maximize generalizability? Fourth, how well do the methods considered compare with one another with respect to prediction generalizability? To address these questions, the author developed various types of predictive models on the basis of Minnesota Multiphasic Personality Inventory (MMPI)-2-RF scales, using multiple prediction criteria, in a calibration inpatient sample, then externally validated those models by applying them to one or two clinical samples from other settings. Model generalizability was then evaluated based on prediction accuracy in the external validation samples.

Equivalence of Laptop and Tablet Administrations of the Minnesota Multiphasic Personality Inventory-2 Restructured Form.

The present study investigated the comparability of laptop computer- and tablet-based administration modes for the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). Employing a counterbalanced within-subjects design, the MMPI-2-RF was administered via both modes to a sample of college undergraduates ( N = 133). Administration modes were compared in terms of mean scale scores, internal consistency, test-retest consistency, external validity, and administration time.
