A taxometric analysis of the latent structure of psychopathy: Evidence for dimensionality.

The taxonomic status of psychopathy is controversial. Whereas some studies have found evidence that psychopathy, at least its antisocial component, is distributed as a taxon, others have found that both major components of psychopathy-callousness/unemotionality and impulsivity/antisocial behavior-appear to distribute as dimensions and show little evidence of taxonicity. In the present study, recent advances in taxometric analysis were added to P. Meehl's (1995) multiple consistency tests strategy for assessing taxonicity, and they were applied to Psychopathy Checklist-Revised (R. D. Hare, 2003) ratings of 4,865 offenders sampled from multiple forensic settings. The results indicated that both the individual components of psychopathy and their interface are distributed dimensionally. Both the implications of these results for research in psychopathy and the integration of these findings with previous taxometric studies of psychopathy are discussed.

Paranoid personality has a dimensional latent structure: Taxometric analyses of community and clinical samples.

Although paranoid personality is one of the most commonly diagnosed personality disorders and is associated with numerous negative life consequences, relatively little is known about the structural properties of this condition. This study examines whether paranoid personality traits represent a latent dimension or a discrete class (i.e., taxon). In Study 1, the authors conducted taxometric analyses of paranoid personality disorder criteria in a sample of 731 patients participating in the Collaborative Longitudinal Study of Personality Disorders project (Gunderson et al., 2000) who had been administered a semistructured diagnostic interview for personality disorders according to criteria of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994). In Study 2, the authors conducted parallel analyses of the Paranoia scale of the Personality Assessment Inventory (PAI; L. C. Morey, 2007), using data from the PAI community and clinical normative databases. Analyses across both self-report and interview-based indicators offered compelling support for a dimensional structure. Additionally, analyses of external correlates in these data sets suggested that dimensional models demonstrated stronger validity coefficients with criterion measures than did dichotomous models.

Evaluating the latent structure of the MMPI-2 F(p) scale in a forensic sample: A taxometric analysis.

P. A. Arbisi and Y. S. Ben-Porath (1995) originally proposed that the Infrequency Psychopathology scale, F(p), be used as the final step in an algorithm to determine the validity of a Minnesota Multiphasic Personality Inventory-2 (MMPI-2) protocol. The current study used taxometric procedures to determine the latent structure of F(p) among examinees with profiles that would necessitate the interpretation of F(p) when using Arbisi and Ben-Porath's proposed algorithm. Participants included a subsample of 289 consecutively referred pretrial forensic examinees adjudicated incompetent to stand trial with high Infrequency (F) scale scores, thereby providing a sample that would be expected to have a high base rate of persons with bona fide psychopathology and persons with incentive to overreport psychopathology. Using MAMBAC and MAXEIG, F(p) produced a taxonic latent structure within the subgroup of examinees who obtained raw scores on F of greater than 17. These results support Arbisi and Ben-Porath's original proposal to use F(p) to identify a distinct subgroup of overreported MMPI-2 protocols within forensic psychiatric examinees with high elevations on F. Implications and suggestions for future research are provided. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Taxometrics, polytomous constructs, and the comparison curve fit index: A Monte Carlo analysis.

The taxometric method effectively distinguishes between dimensional (1-class) and taxonic (2-class) latent structure, but there is virtually no information on how it responds to polytomous (3-class) latent structure. A Monte Carlo analysis showed that the mean comparison curve fit index (CCFI; Ruscio, Haslam, & Ruscio, 2006) obtained with 3 taxometric procedures—mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent mode factor analysis (L-Mode)—accurately identified 1-class (dimensional) and 2-class (taxonic) samples and produced taxonic results when applied to 3-class (polytomous) samples. From these results it is concluded that using the simulated data curve approach and averaging across procedures is an effective way of distinguishing between dimensional (1-class) and categorical (2 or more classes) latent structure.

Moral judgment and moral action: A reanalysis of Haan, Smith, and Block's (1968) Free Speech Movement data.

Data from Haan, Smith, and Block's (1968) study of the relation of moral reasoning to sitting-in during the Free Speech Movement protest at the University of California in 1964 was reanalyzed using the current moral judgment scoring system. The original authors had found a bimodal pattern. In their study, more than half of the subjects who reasoned at both the lowest and highest levels of moral development sat in compared with 11% of the subjects reasoning at the middle level. Results of the current reanalysis show a monotonic pattern. At each higher stage of moral reasoning represented in the sample, a greater proportion of subjects sat in (i.e., Stage 3, 10%, Stage 3/4, 31%, Stage 4, 44%, Stage 4/5, 73%). Although moral stage was the most theoretically important correlate of sitting in, it was not the largest. Political identification, deontic choice, and moral type were even more strongly related to sitting in than was moral stage. An effect of sex on moral stage was found but there was no sex effect on sitting in or on the Stage?×?Sitting-In interaction. The data are discussed in terms of a more general model of moral reasoning and moral action. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A comparison of inclusive and restrictive strategies in modern missing data procedures.

Two classes of modem missing data procedures, maximum likelihood (ML) and multiple imputation (MI), tend to yield similar results when implemented in comparable ways. In either approach, it is possible to include auxiliary variables solely for the purpose of improving the missing data procedure. A simulation was presented to assess the potential costs and benefits of a restrictive strategy, which makes minimal use of auxiliary variables, versus an inclusive strategy, which makes liberal use of such variables. The simulation showed that the inclusive strategy is to be greatly preferred. With an inclusive strategy not only is there a reduced chance of inadvertently omitting an important cause of missingness, there is also the possibility of noticeable gains in terms of increased efficiency and reduced bias, with only minor costs. As implemented in currently available software, the MI approach tends to encourage the use of a restrictive strategy, whereas the MI approach makes it relatively simple to use an inclusive strategy.

A Latent Markov Model for the Analysis of Longitudinal Data Collected in Continuous Time: States, Durations, and Transitions.

Markov models provide a general framework for analyzing and interpreting time dependencies in psychological applications. Recent work extended Markov models to the case of latent states because frequently psychological states are not directly observable and subject to measurement error. This article presents a further generalization of latent Markov models to allow for the analysis of rating data that are collected at arbitrary points in time. This extension offers new ways of investigating change processes by focusing explicitly on the durations that are spent in latent states. In an experience sampling application the author shows that such duration analyses can provide valuable insights about chronometric features of emotions.

"MMPI and Rorschach: Three decades of research": A time series reanalysis.

Reanalyzed the results concerning the yearly analysis of references to the Minnesota Multiphasic Personality Inventory (MMPI) and the Rorschach test in Psychological Abstracts from 1950 to 1985 obtained by J. Polyson et al (see record 1987-02840-001), using the auto-regressive integrated moving average model. Findings of the reanalysis reveal a problem with the Polyson et al study, because the sample data did not meet the assumptions of the inferential procedures associated with the t-test and Pearson product-moment r. It is maintained that the number of publications in a given year for either measure did not influence the number of publications for the other measure in any subsequent year.

The Racial and Ethnic Microaggressions Scale (REMS): Construction, reliability, and validity.

Racial microaggressions are subtle statements and behaviors that unconsciously communicate denigrating messages to people of color. In recent years, a theoretical taxonomy and subsequent qualitative studies have introduced the types of microaggressions that people of color experience. In the present study, college- and Internet-based samples of African Americans, Latina/os, Asian Americans, and multiracial participants (N = 661) were used to develop and validate the Racial and Ethnic Microaggression Scale (REMS). In Study 1, an exploratory principal-components analyses (n = 443) yielded a 6-factor model: (a) Assumptions of Inferiority, (b) Second-Class Citizen and Assumptions of Criminality, (c) Microinvalidations, (d) Exoticization/Assumptions of Similarity, (e) Environmental Microaggressions, and (f) Workplace and School Microaggressions, with a Cronbach's alpha of .912 for the overall model and subscales ranging from .783 to .873. In Study 2, a confirmatory factor analysis (n = 218) supported the 6-factor model with a Cronbach's alpha of .892. Further analyses indicate that the REMS is a valid measure of racial microaggressions, as evidenced by high correlations with existing measures of racism and participants' feedback. Future research directions and implications for practice are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Classes of substance abuse relapse situations: A comparison of adolescents and adults.

Research in the process of relapse has uncovered important developmental differences in the situations that make adolescents and adults most vulnerable to relapse after substance abuse treatment. This study takes a developmental, person-centered approach to relapse by examining the latent class structure of relapse precursors in adolescents and adults. Adults (N = 160) and adolescents (N = 188) in substance abuse and psychiatric treatment were followed up to 18 months after discharge to gather detailed information about their first relapse after treatment. Both adolescents and adults exhibited a 2-class structure of relapse precursors. Adult classes were labeled social and urges situations (primary precursors: social pressure and urges; 67%) and negative and urges situations (primary precursors: negative affect and urges; 33%), while teen classes were labeled social and positive situations (primary precursors: enhancing a positive emotional state and social pressure; 69%) and complex situations (primary precursors: negative affect, negative interpersonal situations, social pressure, and urges; 31%). Findings are discussed in relation to developmental and clinical considerations in treating clients with substance use disorders and comorbid psychopathology.

Mini-Mental State Examination (MMSE) and the Modified MMSE (3MS): A psychometric comparison and normative data.

The Mini-Mental State Examination (MMSE; M. F. Folstein, S. E. Folstein, & P. R. McHugh, 1975) and the Modified MMSE (E. L. Teng & H. C. Chui, 1987) were compared psychometrically. In this study, 525 community-dwelling participants, aged 65–89, were divided into 2 groups: no cognitive impairment (NCI; n?=?406) and Alzheimer's disease (n?=?119). Both tests yielded comparable reliability estimates. Fewer years of education decreased specificity and increased sensitivity, whereas increasing age primarily decreased specificity. It is concluded that although the 2 tests produce comparable effects, the inclusion of a verbal fluency test would increase the sensitivity of the MMSE. Normative data for the NCI group, stratified for 2 age levels (65–79 and 80–89) and 2 educational levels (0–8 and 9+ years), are presented.

The Rorschach: Facts, fictions, and future.

A large body of empirical evidence supports the reliability, validity, and utility of the Rorschach. This same evidence reveals that the recent criticisms of the Rorschach are largely without merit. This article systematically addresses several significant Rorschach components: interrater and temporal consistency reliability, normative data and diversity, methodological issues, specific applications in the evaluation of thought disorder and suicide, meta-analyses, incremental validity, clinician judgment, patterns of use, and clinical utility. Strengths and weaknesses of the test are addressed, and research recommendations are made. This information should give the reader both an appreciation for the substantial, but often overlooked, research basis for the Rorschach and an appreciation of the challenges that lie ahead.

Variations of emotional display rules within and across cultures: A comparison between Canada, USA, and Japan.

This study investigates emotional display rules for seven basic emotions. The main goal was to compare emotional display rules of Canadians, US Americans, and Japanese across as well as within cultures regarding the specific emotion, the type of interaction partner, and gender. A total of 835 university students participated in the study. The results indicate that Japanese display rules permit the expression of powerful (anger, contempt, and disgust) significantly less than those of the two North American samples. Japanese also think that they should express positive emotions (happiness, surprise) significantly less than the Canadian sample. Furthermore, Japanese varied the display rules for different interaction partners more than the two North American samples did only for powerful emotions. Gender differences were similar across all three cultural groups. Men expressed powerful emotions more than women and women expressed powerless emotions (sadness, fear) and happiness more than men. Depending on the type of emotion and interaction partner some shared display rules occurred across culture and gender. The implications of these findings are discussed in relation to cultural dimensions and other cultural characteristics. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Inference in regression models of heavily skewed alcohol use data: A comparison of ordinary least squares, generalized linear models, and bootstrap resampling.

Analysis of alcohol use data and other low base rate risk behaviors using ordinary least squares regression models can be problematic. This article presents 2 alternative statistical approaches, generalized linear models and bootstrapping, that may be more appropriate for such data. First, the basic theory behind the approaches is presented. Then, using a data set of alcohol use behaviors and consequences, results based on these approaches are contrasted with the results from ordinary least squares regression. The less traditional approaches consistently demonstrated better fit with model assumptions, as demonstrated by graphical analysis of residuals, and identified more significant variables potentially resulting in theoretically different interpretations of the models of alcohol use. In conclusion, these models show significant promise for furthering the understanding of alcohol-related behaviors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Clarifying the role of social comparison in the big-fish–little-pond effect (BFLPE): An integrative study.

It has been speculated that the big-fish–little-pond effect (BFLPE; the negative impact of highly selective academic settings on academic self-concept) is a consequence of invidious social comparisons experienced in higher ability schools. However, the direct role of such comparisons for the BFLPE has not heretofore been documented. The present study comprises the first evidence that the BFLPE (a) is eliminated after controlling for students’ invidious comparisons with their class and (b) coexists with the assimilative and contrastive effects of upward social comparison choices on academic self-concept. These results increase understanding of the BFLPE and offer support for integrative approaches of social comparison (selective accessibility and interpretation comparison models) in a natural setting. They also lend support for the distinction between forced and deliberate social comparisons and the usefulness of distinguishing between absolute and relative comparison-level choice in self-assessment.

On the adequacy of the Wide Range Achievement Test (WRAT): A reply to Snart, Dennis, and Brailsford.

Replies to comments by Snart, Dennis, and Brailsford (see record 1984-02928-001) voicing concerns about the validity of the Wide Range Achievement Test (WRAT). They have concluded that the WRAT overestimates the performance of Canadian children. They have also noted that the WRAT measures only word recognition and that word recognition is overemphasized as a measure of "reading." The present author addresses what are seen to be "fundamental" problems with their arguments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Culture, gender, and the self: Variations and impact of social comparison processes.

Psychological differences between women and men, far from being invariant as a biological explanation would suggest, fluctuate in magnitude across cultures. Moreover, contrary to the implications of some theoretical perspectives, gender differences in personality, values, and emotions are not smaller, but larger, in American and European cultures, in which greater progress has been made toward gender equality. This research on gender differences in self-construals involving 950 participants from 5 nations/cultures (France, Belgium, the Netherlands, the United States, and Malaysia) illustrates how variations in social comparison processes across cultures can explain why gender differences are stronger in Western cultures. Gender differences in the self are a product of self-stereotyping, which occurs when between-gender social comparisons are made. These social comparisons are more likely, and exert a greater impact, in Western nations. Both correlational and experimental evidence supports this explanation.

Psychometric Properties of the Posttraumatic Cognitions Inventory (PTCI): A Replication With Motor Vehicle Accident Survivors.

This study examined the factor structure, internal consistency, concurrent validity, discriminant validity, and discriminative validity of the Posttraumatic Cognitions Inventory (PTCI; E. B. Foa, A. Ehlers, D. M. Clark, D. F. Tolin, & S. M. Orsillo, 1999) in a sample of 112 individuals who had experienced a serious motor vehicle accident. Results generally supported the 3-factor structure of the PTCI: (a) Negative Cognitions About Self, (b) Negative Cognitions About the World, and (c) Self-Blame. Subscales reflecting negative thoughts of the self and world showed adequate internal consistency, as well as good concurrent, discriminant, and discriminative validity. However, difficulties with the subscale representing self-blame emerged, specifically poor concurrent and discriminant validity. Potential reasons for this finding are discussed. The PTCI seems to be a promising measure of negative and dysfunctional posttrauma cognitions, which deserves continuing attention. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Discrepancy in Analyses of the MSCEIT--Resolving the Mystery and Understanding Its Implications: A Reply to Gignac (2005).

Replies to comments made by G. E. Gignac (see record 2005-06671-010) on the current authors' original article (see record 2003-02341-015). Gignac reanalyzed the factor structure of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and found results that differed from those the authors obtained initially. The authors tracked down the surprising sources of those discrepancies. G. E. Gignac's hierarchical model of emotional intelligence appears promising, and the authors anticipate that further investigations of the MSCEIT factor structure may yield additional information.

Review of Relative deprivation and social comparison: The Ontario Symposium, Volume 4.

Reviews the book, Relative deprivation and social comparison: The Ontario Symposium, Volume 4 edited by James M. Olson, C. Peter Herman, and Mark P. Zanna (1986). This volume addresses two very important and interrelated topics in social psychology through a collection of relatively independent papers. Following an introductory chapter, the authors of chapters 2 through 5 discuss various theoretical approaches to the determinants of resentment engendered by relative deprivation and recent research designed to address this theorizing. Then, chapters 6 through 8 discuss recent work on social comparison processes. Finally, chapters 9 through 12 use the concepts of relative deprivation and social comparison to suggest ways to understand four important social issues: minority-majority relations, dissatisfaction in organizational settings, social protest, and tolerance of injustice. All in all, the reviewer highly recommends this book to anyone wishing to update themselves on current research trends in this area. Two of the three sections are excellent and third is of uneven rather than poor quality. Further, the regrettable focus on egotistical rather than fraternal relative deprivation in the social psychology literature is not as prevalent in this book as the reviewer feared it might be.
