The Diagnostic and Statistical Manual for Mental Disorders-5th Edition (DSM-5; American Psychiatric Association [APA], 2013) includes an alternate model for the assessment and diagnosis of personality disorders (PDs). This model is a hybrid dimensional-categorical model that includes functional impairment, maladaptive personality traits, and a set of categorical PD diagnoses. Previous research has begun to evaluate the different aspects of this model, particularly its trait model (see Krueger & Markon, 2014 for a review); however, additional research is needed that addresses the clinical utility of the model, the role of functional impairment in PD assessment, and validity of measure designed to assess the model (e.g., the Personality Inventory for DSM-5 [PID-5] and its alternate forms). The following studies aimed to fill those gaps in the literature. Study One evaluated clinical perspectives of Borderline (BPD) and Antisocial (ASPD) PDs using Section III dimensional traits and supported the use of these traits in operationalizing these two disorders in clinical practice. Study Two examined the functional impairment criteria of the model as they relate to specific PDs. This study suggested a lack of utility in measuring disorder-specific impairment due to overlap across PDs and instead suggested the use of more broad constructs of impairment. In addition, however, this study highlighted some of the overlap between functional impairment and maladaptive traits in this model, as described by other previous researchers (e.g., Zimmerman et al., 2015) and called for additional research regarding the utility of this criterion. Finally, Study Three evaluated a screening measure for the Section III trait domains, the PID-5-Brief Form (PID-5-BF; APA, 2013; Derringer et al., under review). This study found support for the factor structure of this measure as well as its construct validity as measured by its association with relevant external criterion variables. Although more research continues to be needed regarding the use of this alternative model, these studies have implications for its implementation and generally support the use of dimensional traits in the assessment and diagnosis of personality psychopathology.

Understanding the Emotional Disorders is the first manual for how to use the IDAS-II and examines important, replicable symptom dimensions contained within five adjacent diagnostic classes in the DSM-5: depressive disorders, bipolar and related disorders, anxiety disorders, obsessive-compulsive and related disorders, and trauma- and stressor-related disorders.

The DSM-5 promises to be a major reformulation of psychopathology, and no section is likely to change diagnostic practice more than that of personality pathology. Unlike the DSM-IV, the DSM-5 personality disorders will be conceptualized as involving core deficits in interpersonal and self-functioning, and will utilize a hybrid assessment model involving both pathological trait dimensions and a limited set of personality disorder types. These changes are based on empirical and theoretical work conducted during the era of DSM-III/IV, but nevertheless there is significant disagreement among personality assessors regarding the DSM-5 proposal. In this volume, several members of the DSM-5 work group offer rationales for the proposal and offer empirical evidence regarding suggested changes, and several personality assessment researchers critique the proposal and offer alternative conceptualizations. This book was originally published as a special issue of the Journal of Personality Assessment.

Full exploitation of the DSM-5 allows for more comprehensive care By demystifying the DSM-5, author Sophia Dziegielewski goes beyond the traditional diagnostic assessment and suggests both treatment plans and practice strategy. She covers the changes in criteria to the DSM-5 and what those changes mean for mental health professionals. This resource has been updated to include: New and updated treatment plans All treatment plans, interventions strategies, applications, and practice implications are evidence based Instructions on doing diagnostic assessments and differential diagnosis using the DSM-5 Changes to coding and billing using the DSM-5 and ICD-10 The book includes robust tools for students, instructors, and new graduates seeking licensure. DSM-5 in Action makes the DSM-5 accessible to all practitioners, allowing for more accurate, comprehensive care.

How to use the dark triad in personnel selection Presents the latest research and theories Highlights the gains and risks of these traits Provides concrete recommendations for use in selection processes Summarizes legal and professional guidelines More about the book This book explores the theoretical basis and state of the art of research on narcissism, Machiavellianism, and subclinical psychopathy. It also answers complex questions on the structure of the dark triad and its measurement for practical applications. Learn about how people high in these characteristics can, on the one hand, experience individual career success and high work performance and, on other hand, present risks in the workplace with abusive and destructive leadership and counterproductive behavior. In addition, the author summarizes the legal and professional guidelines when assessing the dark personality characteristics of job applicants, examines the acceptance and social validity of such assessments, evaluates the available instruments, and makes recommendations for practical applications and further research. With the focus on practical applications, the book presents the development, quality, and application of a test designed for use in organizations to capture the dark triad in the workplace. Concrete recommendations are given on how to use the characteristics narcissism, Machiavellianism, and subclinical psychopathy in personnel selection. Researchers and practitioners interested in applying the dark triad in personnel work will find this book full of valuable information on how to undertake legally compliant processes and how to utilize the great potential these personality characteristics have in making decisions on aptitude.

The DSM-5 Alternative Model for Personality Disorders reviews and advances this innovative and increasingly popular scheme for diagnosing and evaluating personality disorders. The authors identify the multiple clinical, theoretical, and research paradigms that co-exist in the Alternative Model for Personality Disorders (AMPD) and show how the model can aid the practicing mental health professional in evaluating and treating patients as well as its importance in stimulating research and theoretical understanding of this domain. This work explores and summarizes methods of personality assessment and psychiatric evaluation, research findings, and clinical applications of the AMPD, highlighting its usefulness to clinical teaching and supervision, forensic application, and current research. It is a go-to reference for experienced professionals and researchers, those who wish to learn this new diagnostic system, and for clinicians in training.

The Alternate Model of Personality Disorders in the DSM-5 Section III Emerging Models and Measures presents a new model of personality pathology (DSM-5 trait model). Several different methods of measurement exist to assess these personality constructs, most prominently the Personality Inventory for DSM-5 (PID-5), of which there are self-report, informant-report, and two abbreviated self-report forms. This model has received extensive empirical attention. At present, however, the PID-5 has questionable structural validity, largely due to interstitial lower-order facets that relate to more than one domain. Further, there is inconsistent domain scoring across studies. Consequently, researchers are conceptualizing the PID-5 higher-order domains in different ways and scoring these domains differentially, which could influence the comparability of research findings and clinical utility of the DSM-5 trait model. The current research aims to address these issues through two studies that employ large clinical (N = 388) and undergraduate (N = 492) samples. In Study 1, the results from a network analytic approach were compared to existing factor analytic results of PID-5 lower-order structure, in efforts to clarify the optimal primary domain of interstitial facets. The combined network and factor analytic results supported the model modification of three facets to a different primary domain based on the PID-5 structure introduced by Krueger and colleagues (2012). The differences in results produced by several PID-5 domain scoring methods and two forms of the PID-5 were compared in Study 2. The findings supported instances in which a substantial difference in results occurred because of different domain scoring methods or PID-5 forms. This research contributes to ongoing efforts to validate the DSM-5 trait model and PID-5 instruments, raises awareness that these discrepancies regarding model structure exist, and offers future directions that could assist in improving inconsistent structure and communication between researchers, clinicians, and institutions utilizing the model.

The examination of personality and individual differences is a major field of research in the modern discipline of psychology. Concerned with the ways humans develop an organised set of characteristics to shape themselves and the world around them, it is a study of how people come to be ‘different’ and ‘similar’ to others, on both an individual and a cultural level. The SAGE Handbook of Personality and Individual Difference is the broadest and most comprehensive overview of the field to date. With outstanding contributions from leading scholars across the world, this is an invaluable resource for researchers and graduate students. Its three volumes cover all of the central concepts, domains and debates of this globally-expanding discipline, including the core theoretical perspectives, research strategies, as well as the origins, applications, and measurement of personality and individual difference.
