ABSTRACT
In this chapter, the goal is to provide the reader with a brief introduction to Criterion B of the DSM-5 Alternative Model of Personality Disorders (AMPD). Criterion B encapsulates an empirical model of maladaptive personality characteristics, the AMPD trait model (AMPD-TM). This model was developed by beginning with observations of DSM-5 Personality and Personality Disorder Work Group members about characteristics they observed in interacting with personality disordered patients. Those characteristics were operationalized in an assessment instrument, the Personality Inventory for DSM-5 (PID-5). The chapter reviews the development of the AMPD-TM and the corresponding PID-5 instrument, with a particular emphasis on strategic considerations that guided this effort, and ways in which the AMPD-TM has resonated in the literature after the publication of the DSM-5 in 2013.
