This chapter will examine the practical applications of the World Health Organization’s International Statistical Classification of Diseases and Related Health Problems, 11th Edition (ICD-11) conceptualization of personality disorders (PD), with a specific focus on how clinicians can utilize its two main components—the global level of severity of P...

Malignant narcissism describes a personality disorder that encompasses five core components: narcissism, psychopathy, sadism, paranoia, and aggressiveness. Despite the extensive theoretical and clinical literature on malignant narcissism and its recent momentum in the popular discourse, there is a dearth of empirical evidence on the syndrome. The o...

Emerging dimensional models of personality disorders such as the Alternative DSM‐5 Model for Personality Disorders (AMPD) provide new opportunities to explore the associations between personality pathology and harmful interpersonal behaviours such as stalking perpetration. Two goals are pursued by this study: (a) To document associations between st...

Research has shown so far the efficacy of day hospital treatment programs for patients with a personality disorder experiencing a crisis episode. However, relatively few studies have relied on a dimensional definition of personality pathology, despite the rise of dimensional models of personality disorders in recent years. The objective of this stu...

Despite research linking the Dark Triad to negative mental health outcomes, data focusing on Machiavellianism, psychopathy, and narcissism altogether in clinical populations are lacking, and brief Dark Triad measures have yet to be validated in clinical populations. This study focuses on documenting the psychometric properties of the Dark Triad Dir...

The Alternative Model for Personality Disorders (AMPD), included in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) and the World Health Organization's International Classification of Diseases (11th ed.; ICD-11) are, respectively, hybrid categorical-dimensional and dimensional frameworks for personality disorders (PDs). Both mod...

The current study focuses on the development and validation of a scoring procedure for malignant narcissism using the Personality Inventory for DSM-5, a self-report measure of Criterion B from the Alternative Model for Personality Disorders. In Study 1, a prototype matching approach was used to aggregate ratings from 15 clinicians specializing in p...

Stalking and obsessive relational intrusions both refer to a pervasive and unwanted pattern of pursuit behaviors, the former being a criminal offense evoking fear and a sense of menace in the victim, while the latter may be perceived as annoying or otherwise undesirable, but not necessarily fear inducing. While the individual and societal costs of...

Background: The 11th version of the World Health Organization's International Classification of Diseases (ICD-11) has adopted a dimensional approach to personality disorder (PD) nosology. Notably, it includes an assessment of PD degree of severity, which can be classified according to five categories. To date, there is no gold standard measure for...

Background There have been multiple attempts to try to parse out heterogeneity within borderline pathology by identifying patient subtypes; thus far, these works have yielded few consistent results. Recent developments in the operationalization of borderline pathology may provide new opportunities to identify clinically and conceptually meaningful...
