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

A critique of the proposed prototype rating system for personality disorders in DSM-5.
TL;DR: If the prototype matching dimensional approach described in the DSM-5 draft proposal is adopted, then it will have been adopted with essentially no empirical support demonstrating improved reliability or validity.

TL;DR: The impressive accuracy of the CCFI was consistent with prior findings and robust across novel manipulations of asymmetry, tail weight, and heterogeneous variances, as well as the practical implications for differentiating categories and dimensions.

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.
