Clinical Utility of the MMPI–2 Restructured Clinical (RC) Scales in Therapeutic Assessment: A Case Study

Summary: In a recent paper, Haan and Livson reported sex differences between male and female psychologists in their evaluations of adult men and adult women. Their conclusions have implication for the validity of clinical, assessments and were interpreted in terms of stereotypic sex rote perceptions. However, their statistical analysis was in fundamental error. When the data they employed were reanalyzed, no reliable sex differences between men and women psychologists were found, a finding in accord with a number of previous investigations of this problem.     

Model Conditioned Data Elasticity in Path Analysis: Assessing the “Confoundability” of Model/Data Characteristics

Much research has been directed at the validity of fit indices in Path Analysis and Structural Equation Modeling (e.g., Browne, MacCallum, Kim, Andersen, &; Glaser, 2002 Browne, M.W., MacCallum, R.C., Kim, C.T., Andersen, B.L., &; Glaser, R.

Reply to Rodgers and Rowe (2002). Psychological Review, 109(3), 605–607.[Crossref] , [Google Scholar]) have encouraged researchers to investigate other criteria for comparing models, including model complexity. What has not been investigated is the inherent ability of a particular data set to be fitted with a constrained set of randomly generated linear models, which we call Model Conditioned Data Elasticity (DE). In this article we show how DE can be compared with the problem of equivalent models and a more general problem of the “confoundability” of data/model combinations (see MacCallum, Wegener, Uchino, &; Fabrigar, 1993 MacCallum, R.C., Wegener, D.T., Uchino, B.N., &; Fabrigar, L.R. (1993). The problem of equivalent models in applications of covariance structure analysis. Psychological Bulletin, 114(1), 185–199.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Using the DE package in R, we show how DE can be assessed through automated computer searches. Finally, we discuss how DE fits within the controversy surrounding the use of fit statistics.     

Hyperactivity in boys with attention deficit/hyperactivity disorder (ADHD): The association between deficient behavioral inhibition,attentional processes,and objectively measured activity

Contemporary models of ADHD hypothesize that hyperactivity reflects a byproduct of inhibition deficits. The current study investigated the relationship between children's motor activity and behavioral inhibition by experimentally manipulating demands placed on the limited-resource inhibition system. Twenty-two boys (ADHD = 11, TD = 11) between the ages of 8 and 12 years completed a conventional stop-signal task, two choice-task variants (no-tone, ignore-tone), and control tasks while their motor activity was measured objectively by actigraphs placed on their nondominant wrist and ankles. All children exhibited significantly higher activity rates under all three experimental tasks relative to control conditions, and children with ADHD moved significantly more than typically developing children across conditions. No differences in activity level were observed between the inhibition and noninhibition experimental tasks for either group, indicating that activity level was primarily associated with basic attentional rather than behavioral inhibition processes.     

Surprise influences hindsight–foresight differences in temporal judgments of animated automobile accidents

The hindsight bias occurs when people view an outcome as more foreseeable than it actually was. The role of an outcome’s initial surprise in the hindsight bias was examined using animations of automobile accidents. Twenty-six participants rated the initial surprise of accidents’ occurring in eight animations. An additional 84 participants viewed these animations in one of two conditions: Half stopped the animations when they were certain an accident would occur (i.e., in foresight), and the other half watched the entire animations first and then stopped the animations when they thought that a naïve viewer would be certain that an accident would occur (i.e., in hindsight). When the accidents were low in initial surprise, there were no foresight–hindsight differences; when initial surprise was medium, there was a hindsight bias; and when initial surprise was high, there was a reversed hindsight bias. The results are consistent with a sense-making model of hindsight bias.     

Mechanisms of inferential order judgments in humans (Homo sapiens) and rhesus monkeys (Macaca mulatta)

If A > B, and B > C, it follows logically that A > C. The process of reaching that conclusion is called transitive inference (TI). Several mechanisms have been offered to explain transitive performance. Scanning models claim that the list is scanned from the ends of the list inward until a match is found. Positional discrimination models claim that positional uncertainty accounts for accuracy and reaction time patterns. In Experiment 1, we trained rhesus monkeys (Macaca mulatta) and humans (Homo sapiens) on adjacent pairs (e.g., AB, BC, CD, DE, EF) and tested them with previously untrained nonadjacent pairs (e.g., BD). In Experiment 2, we trained a second list and tested with nonadjacent pairs selected between lists (e.g., B from List 1, D from List 2). We then introduced associative competition between adjacent items in Experiment 3 by training 2 items per position (e.g., B?C?, B?C?) before testing with untrained nonadjacent items. In all 3 experiments, humans and monkeys showed distance effects in which accuracy increased, and reaction time decreased, as the distance between items in each pair increased (e.g., BD vs. BE). In Experiment 4, we trained adjacent pairs with separate 9- and 5-item lists. We then tested with nonadjacent pairs selected between lists to determine whether list items were chosen according to their absolute position (e.g., D, 5-item list > E, 9-item list), or their relative position (e.g., D, 5-item list < E, 9-item list). Both monkeys' and humans' choices were most consistent with a relative positional organization.     

Associations between Symptom Validity Test failure and scores on the MMPI-2-RF validity and substantive scales

This study examined the association between Symptom Validity Test (SVT) failure and the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008), in the Forensic Disability Claimant samples described in the MMPI-2-RF Technical Manual (Tellegen & Ben-Porath, 2008 a, 2008b). SVTs used included the Word Memory Test (Green, 2003), the Computerized Assessment of Response Bias (Allen, Conder, Green, & Cox, 1997), the Medical Symptom Validity Test (Green, 2004), and the Test of Memory Malingering (Tombaugh, 1996). SVT failure was associated with significant elevations throughout the MMPI-2-RF overreporting validity scales and substantive scales. Pairwise contrasts between groups failing 0 and 3 SVTs revealed predominantly large effect sizes for the overreporting validity scales (d = 0.78-1.11), and many of the substantive scales, including the Cognitive Complaints (COG) scale. Results of this study demonstrate an association between SVT performance and elevated scores on the MMPI-2-RF. These results suggest that exaggeration of cognitive symptoms as demonstrated by SVT failure is also associated with overreported emotional, somatic, and neurocognitive complaints on the MMPI-2-RF.     

The callousness pathway to severe violent delinquency

Children and adolescents who exhibit a callous interpersonal style seem to be at risk for developing severe forms of violent behavior. Theoretical models suggest that children with low levels of temperamental fearfulness may be at increased risk for developing callous traits because they are relatively unaffected by punishment. This study examines hypotheses about the callousness pathway to severe violent delinquency in a cross‐sectional sample of 169 (97=males, 72=females) adjudicated adolescents. Structural equation modeling is used to test mediation models regarding the relation between temperamental fear, punishment concern, callousness, and severe violent delinquency. The findings of the study indicate that the relation between low levels of temperamental fear and increased callousness is mediated by a lack of concern about being punished for aggressive acts. Although low levels of fear and punishment concern were both related to increased levels of severe violent delinquency, increased levels of callousness mediated these relations. All findings remained significant after controlling for the potential confounds of gender, race, and social desirability. The results provide a heuristic for understanding the callousness pathway to severe violent behavior in youth. However, longitudinal investigations replicating these results are necessary before firm conclusions can be drawn. Aggr. Behav. 32:590–598, 2006. © 2006 Wiley‐Liss, Inc.     

A Validation of the Inventory of Callous-Unemotional Traits in a Community Sample of Young Adult Males

Callous-unemotional (CU) traits have been shown to delineate a subgroup of individuals at high risk for exhibiting severe and persistent criminal behavior. The Inventory of Callous-Unemotional Traits (ICU; Frick 2004) was recently developed as a comprehensive rating scale designed to measure multiple facets of CU traits. However, validation of this measure has been limited to youth in adolescence and emerging adulthood (age range?=12–20), leaving questions about the utility of this measure in early adulthood unanswered. The current study evaluated the factor structure of the ICU within a racially diverse and well characterized community sample of adult males (n?=?425) using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). While results found the best fitting model to be the three-bifactor structure that has been previously reported in adolescent samples, the fit indices were only marginally acceptable and suggest the need for scale refinement. Total and subscales scores demonstrated significant and distinct associations with relevant external criteria (e.g., delinquency, psychopathy, psychopathology, psychosocial functioning). Implications and directions for future research are discussed.     

Adolescent Dating Violence: Application of a U.S. Primary Prevention Program in St. Lucia

The purpose of this study was to examine the Choose Respect dating violence prevention program (Centers for Disease Control and Prevention, 2006b , n.d.‐a) with secondary students in St. Lucia. Multivariate analysis of variance results indicated that the Choose Respect program had a positive influence on participants’ attitudes about control in relationships. Significant gender and school effects were found. Implications of these findings for primary prevention efforts targeting dating violence in St. Lucia and limitations of the study are discussed.
