A prototype matching approach to diagnosing personality disorders: toward DSM-V.
The current diagnostic system for personality disorders (PD) has a number of problems that may require a thorough revision for DSM-V. This article (a) outlines problems with the current taxonomy that suggest the need for a different approach to PD diagnosis that preserves the strengths of the current system while addressing some inherent weaknesses; (b) discusses key issues that must be addressed in moving toward DSM-V, such as revising the distinction between Axis I and Axis II and combining categorical and dimensional diagnosis; and (c) describes a prototype matching approach to diagnosis, which we believe has the potential to be both psychometrically sound and faithful to the clinical data.
