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

Assessing interpersonal functioning: Views from within and without
TL;DR: This paper applied the traditional methods of these three research strands (questionnaires, interviews, and interpersonal role-plays) to the same sample and found that participants who attributed higher levels of interpersonal problems to themselves in general were also more critical of their own role-play performances, but these impressions were not mirrored by observer-ratings.

Comparing the dependability and associations with functioning of the DSM-5 Section III trait model of personality pathology and the DSM-5 Section II personality disorder model.
TL;DR: The findings indicate that most DSM–5 traits demonstrate high levels of dependability that are superior to the traditional PD model; however, some of the constructs assessed by the PID-5 may be more state like.

Exploring the Assessment of the DSM–5 Alternative Model for Personality Disorders With the Personality Assessment Inventory
TL;DR: This study sought to develop scoring algorithms for these alternative model concepts using scales from the Personality Assessment Inventory (PAI), and results were linked to the PAI community normative data to provide normative information regarding theseAlternative model concepts that can be used to identify elevated traits and personality functioning level scores.

TL;DR: The best fitting biometric model for 4 of the 6 domains of maladaptive personality was one in which genetic and environmental influences could be set invariant across gender, and multiple group confirmatory factor modeling provided evidence that all 6 domain scale measurement models were gender-invariant.

Clinicians and clients disagree: Five implications for clinical science.
TL;DR: Evidence that, despite criticisms, self-reported psychopathology may be at least as valid as clinicians' unstructured diagnoses is provided, and the need for research that provides clinicians with the most valid tools, including those that focus on dimensional constructs, rather than diagnostic categories is highlighted.

Construct validity in psychological tests.

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.
