Introduction to the Special Section on Mixture Modeling in Personality Assessment

Latent variable models offer a conceptual and statistical framework for evaluating the underlying structure of psychological constructs, including personality and psychopathology. Complex structures that combine or compare categorical and dimensional latent variables can be accommodated using mixture modeling approaches, which provide a powerful framework for testing nuanced theories about psychological structure. This special series includes introductory primers on cross-sectional and longitudinal mixture modeling, in addition to empirical examples applying these techniques to real-world data collected in clinical settings. This group of articles is designed to introduce personality assessment scientists and practitioners to a general latent variable framework that we hope will stimulate new research and application of mixture models to the assessment of personality and its pathology.     

Introduction to the Special Issue on Personality Assessment in Medical Settings

Rouse, Greene, Butcher, Nichols, and Williams (2008) Sellbom, M., Ben-Porath, Y. S. and Bagby, R. M. 2008a. On the hierarchical structure of mood and anxiety disorders: Confirmatory evidence and an elaboration of a model of temperament markers. Journal of Abnormal Psychology, 117: 576–590. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] repeat two claims about the MMPI–2 Restructured (RC) scales. One asserts that the correlations of RC scales with parent Clinical scales are modest compared to the correlations with other existing MMPI–2 scales. In response, we reiterate that the RC scales were not meant to emulate the divergent and overlapping content of the Clinical scales. Instead, each represents a distinctive Clinical scale component. Although individually focused, the RC scales span collectively a wide range of content and used as multivariate predictors, account for most of the variance of each Clinical scale. Rouse et al. also claim that most RC scales are redundant with existing MMPI–2 scales, which they propose as substitutes (“proxies”). However, our analyses of Rouse et al.'s database and of our own data show that several of their proposed proxies are far less mutually distinguishable than are the RC scale counterparts. Furthermore, several Clinical scales are more successfully, and none are less successfully, accounted for by RC scales than by proxies. In response to Rouse et al.'s neglect of a body of empirical findings supporting the construct validity of the RC scales, we also review the relevant research literature.     

Development of Borderline Personality Disorder in Adolescence and Young Adulthood: Introduction to the Special Section

Recognizable symptoms and features of borderline personality disorder (BPD) appear during adolescence. However, there has been resistance to diagnose or research this disorder prior to adulthood because of clinical lore that BPD is a long-standing illness and that personality traits are not stable until adulthood. This has resulted in little information regarding the development of and risk factors for BPD in youth. The goal of this special section is to examine the development of BPD in adolescence and young adulthood using a broad collection of approaches, including a theoretical review paper, two prospective studies, and a multi-method cross-sectional study. This body of work provides new insights into vulnerabilities that may transact with early attachment relationships and experiences to predict the emergence of BPD in adolescence and young adulthood. These papers also point to future research that is needed to better understand the etiology, development, and course of BPD.     

Introduction to the Special Section

This study adopted a dialectical framework to provide insight into the doctoral advisement relationship early in the dissertation phase in different disciplines. Interpretive analysis of in-depth interviews with 6 advisor–student pairs revealed the variety of ways that the autonomy–guidance dialectic was conceptualized and experienced. It also illustrated moments when the advisor and student were not synchronized in their perceptions. Implications are considered.     

Introduction to the Special Issue on the Role of Personality Assessment in Consulting to Organizations

This special issue aims to advance the integration of personality assessment across applied contexts. Personality assessment is an integral part of clinical and organizational case conceptualizations, intervention planning, and change efforts. Yet, as the present historical account will illustrate, the literatures in relation to personality assessment have developed rather independently. The articles in this special issue highlight the importance of organizational personality assessment as relates to how (a) academics vs. practitioners look at standards for test selection (Furnham), (b) the intended use of tests (selection vs. employee development) impacts the criteria used to establish assessment tool validity (Moyle & Hackston), (c) personality models developed in social and personality psychology can be applied in organizational contexts (Shorey & Chaffin), (d) assessments are modified to more accurately assess operational definitions of constructs (Belwalker & Tobacyk), (e) perception and knowledge about personality of others can be assessed as an ability (Mayer, Lortie, Panter & Caruso), and (f) performance-based techniques can be used in organizational personality assessment to curtail faking and socially desirable responding (Harms, Krasikova & Luthans). The present introduction highlights the important contributions of these articles, individually and as a body, in advancing the integration and application of personality assessment in organizational contexts.
