Clinical correlates of personality pathology using the AMPD-ICD-11 models (1.5 CEs)

Abstract

The classification of personality disorders (PDs) continues its important shift towards dimensional conceptualisations, given the abundant critiques of categorical models. The Alternative DSM-5 Model for PDs (AMPD) took a categorical-dimensional hybrid approach to soften the transition to a fully dimensional model. In 2022, the ICD-11’s chapter on PDs and related traits launched its fully dimensional approach. The core criterion for both models is impairment in self- and interpersonal functioning, labelled personality functioning impairment in the AMPD and severity in ICD-11. Both the AMPD and ICD-11 further apply maladaptive traits to portray stylistic differences in PD expression. Given its longer existence, the AMPD has been extensively researched while evidence for the ICD-11 model is accumulating, and review studies support the clinical utility of both models.

To facilitate the application of AMPD/ICD-11 models in personality assessment and clinical practice more broadly, this symposium will introduce attendees to both frameworks with a focus on how the components of these dimensional personality models connect to important clinical correlates. Michael Bagby will look at associations between AMPD maladaptive traits (measured by PID-5) and traditional PD symptoms using a multi-method approach (clinician-ratings, self-report, and informant-report). Gina Rossi (chair) will discuss how AMPD and ICD-11 personality traits and functioning relate to early maladaptive schemas in later life. She will present empirical evidence on the compatibility of schema therapy model with the AMPD/ICD-11 personality pathology framework. Adam Natoli (co-chair) will provide empirical support from an exploratory study investigating how these models are linked to general health factors and health anxiety. Michael Roche will present how personality functioning impairment and maladaptive traits are related to broad and narrow aspects of externalizing pathology in daily life and on a day-to-day basis. Abby Mulay will examine how maladaptive traits connect to clinical scales of an omnibus personality and clinical pathology instrument, the MMPI-2, within a child custody/parental fitness sample.

This symposium will conclude with Robert Krueger, lead author of the Personality Inventory for DSM-5 and an expert in dimensional PD models, serving as discussant. He will provide an integrative conclusion about clinical correlates of the AMPD and ICD-11 models and offer his thoughts on how AMPD/ICD-11 research can evolve to address pertinent assessment and clinical implications for the field.

Goals & Objectives

1. With the aim of facilitating the use of the dimensional AMPD and ICD-11 personality disorder models in clinical practice, this symposium will introduce attendees to the core aspects of personality pathology according to the AMPD and ICD-11 models: maladaptive personality traits and personality functioning. Presentations and discussion will focus on how these core aspects of personality are compatible with frameworks clinicians use, such as schema therapy model, or connect to clinical important aspects (e.g. health concerns or aggression) and can be applied in a variety of settings (e.g. forensic) and populations (e.g. older adults, custody samples).
