Introduction to the Special Series on the Personality Functioning Component of the Alternative DSM-5 Model for Personality Disorders INTRODUCTION

The Alternative DSM-5 Model for Personality Disorders (AMPD; American Psychiatric Association, 2013) was created to remedy the previously well-explicated limitations of the categorical DSM-IV personality disorders. The AMPD combines dimensional assessments of personality functioning (Criterion A) and traits (Criterion B), which can be used independently or together, and serve as the basis for defining six categorical disorder options. The Criterion A Level of Personality Functioning Scale (LPFS) defines a continuum characterized by the four elements of identity, self-direction, empathy, and intimacy. Empirical work related to the LPFS has been growing, and this Journal of Personality Assessment special series features reports from a variety of research groups around the world. 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.
