Plate tectonics in the classification of personality disorder: shifting to a dimensional model.
TLDR
It may be time to consider a shift to a dimensional classification of personality disorder that would help address the failures of the existing diagnostic categories as well as contribute to an integration of the psychiatric diagnostic manual with psychology's research on general personality structure.Abstract:
The diagnostic categories of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders were developed in the spirit of a traditional medical model that considers mental disorders to be qualitatively distinct conditions (see, e.g., American Psychiatric Association, 2000). Work is now beginning on the fifth edition of this influential diagnostic manual. It is perhaps time to consider a fundamental shift in how psychopathology is conceptualized and diagnosed. More specifically, it may be time to consider a shift to a dimensional classification of personality disorder that would help address the failures of the existing diagnostic categories as well as contribute to an integration of the psychiatric diagnostic manual with psychology's research on general personality structure.read more

Reliability, Factor Structure, and Associations With Measures of Problem Relationship and Behavior of the Personality Inventory for DSM-5 in a Sample of Italian Community-Dwelling Adolescents.

TL;DR: Ordinal logistic regression analyses showed that selected PID-5 trait scales predicted a significant, albeit moderate, amount of variance in Questionnaire on Relationships and Substance Use variables, and exploratory structural equation modeling analyses provided moderate support for the a priori model of PID- 5 trait scales.

Introduction to the Special Series on the Personality Functioning Component of the Alternative DSM-5 Model for Personality Disorders.
TL;DR: These studies provide contributions for better understanding the reliability, validity, and utility of the LPFS, as well as describing new measures that have been created to investigate personality functioning.

A Head-to-Head Comparison of the Personality Inventory for DSM-5 (PID-5) With the Personality Diagnostic Questionnaire-4 (PDQ-4) in Predicting the General Level of Personality Pathology Among Community Dwelling Subjects.
Andrea Fossati,Antonella Somma,Serena Borroni,Cesare Maffei,Kristian E. Markon,Robert F. Krueger +5 more
TL;DR: Hierarchical regression analyses revealed that the PID-5 domain and trait scales provided a moderate, but significant increase in the prediction of the general level of personality pathology above and beyond the PDQ-4+ scales.

Understanding adolescent personality pathology from growth trajectories of childhood oddity.
TL;DR: Growing parameters of odd features in a mixed sample of Flemish community and referred children across three measurement waves with 1-year time intervals demonstrated that both an early onset and an increasing trend of oddity-related characteristics over time are independent predictors of adolescent PDs.

Considering the research: Commentary on "The trait-type dialectic: Construct validity, clinical utility, and the diagnostic process".
TL;DR: In sum, Widiger would suggest that the dimensional trait models do translate naturally into diagnoses, are easily communicated to other healthcare professionals, and will account well for the intra- and interpersonal dynamics.

Construct validity in psychological tests.
Lee J. Cronbach,Paul E. Meehl +1 more
TL;DR: The present interpretation of construct validity is not "official" and deals with some areas where the Committee would probably not be unanimous, but the present writers are solely responsible for this attempt to explain the concept and elaborate its implications.
