Key insights from studies on the stability of personality disorders in different age groups.

While for decades, temporal stability has been conceived as a defining feature of personality disorders (PDs), cumulative findings appear to question the stability of PDs and PD symptoms over time. However, stability itself is a complex notion and findings are highly heterogenous. Building upon a literature search from a systematic review and meta-analysis, this narrative review aims to capture key findings in order to provide critical implications, both for clinical practice and future research.

New Zealand (Aotearoa) clinicians' perspectives on the utility of the ICD-11 personality disorder diagnosis.

The ICD-11 has now taken effect and includes a new dimensional personality disorder (PD) diagnosis. The current study aimed to examine Aotearoa/New Zealand practitioners' perceptions of the clinical utility of the new PD system. A sample of 124 psychologists and psychiatrists completed a survey, applying the DSM-5 and ICD-11 PD diagnostic systems to a current patient, and completed clinical utility metrics on the DSM-5 and ICD-11 models.

The ICD-11 classification of personality disorders: a European perspective on challenges and opportunities.

The 11th revision of the World Health Organization (WHO) International Classification of Diseases (ICD-11) includes a fundamentally new approach to Personality Disorders (PD). ICD-11 is expected to be implemented first in European countries before other WHO member states. The present paper provides an overview of this new ICD-11 model including PD severity classification, trait domain specifiers, and the additional borderline pattern specifier.

Shortcomings of approaches to classifying psychopathology based on expert consensus have given rise to contemporary efforts to classify psychopathology quantitatively. In this paper, we review progress in achieving a quantitative and empirical classification of psychopathology. A substantial empirical literature indicates that psychopathology is generally more dimensional than categorical.

How does level of personality functioning inform clinical management and treatment? Implications for ICD-11 classification of personality disorder severity.

Purpose Of Review: The International Classification of Diseases, 11th Edition (ICD-11) classifies personality disturbance according to levels of severity. This article reviews the literature on levels of personality functioning in relation to clinical management and treatment, and proposes how these findings apply to the ICD-11 classification of personality disorders.

Recent Findings: Findings were primarily derived from studies using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) Level of Personality Functioning Scale (LPFS), Kernberg's Level of Personality Organization, and the general P-factor of personality disorder.

Integrating the Hierarchical Taxonomy of Psychopathology (HiTOP) into clinical practice.

Objective: Diagnosis is a cornerstone of clinical practice for mental health care providers, yet traditional diagnostic systems have well-known shortcomings, including inadequate reliability, high comorbidity, and marked within-diagnosis heterogeneity. The Hierarchical Taxonomy of Psychopathology (HiTOP) is a data-driven, hierarchically based alternative to traditional classifications that conceptualizes psychopathology as a set of dimensions organized into increasingly broad, transdiagnostic spectra. Prior work has shown that using a dimensional approach improves reliability and validity, but translating a model like HiTOP into a workable system that is useful for health care providers remains a major challenge.

A Hierarchical Taxonomy of Psychopathology Can Transform Mental Health Research.

For more than a century, research on psychopathology has focused on categorical diagnoses. Although this work has produced major discoveries, growing evidence points to the superiority of a dimensional approach to the science of mental illness. Here we outline one such dimensional system-the Hierarchical Taxonomy of Psychopathology (HiTOP)-that is based on empirical patterns of co-occurrence among psychological symptoms.

Elucidating DSM-5 and ICD-11 Diagnostic Features of Borderline Personality Disorder Using Schemas and Modes.

Background: Borderline personality disorder (BPD) comprises a heterogeneous constellation of problems operationalized in the DSM-5 and the forthcoming ICD-11. In schema therapy, schemas and modes are employed to conceptualize and treat these problems.

Aim: The current study investigated whether the 9 diagnostic BPD features are associated with schemas and modes.

Application of the ICD-11 classification of personality disorders.

Background: The ICD-11 classification of Personality Disorders focuses on core personality dysfunction, while allowing the practitioner to classify three levels of severity (Mild Personality Disorder, Moderate Personality Disorder, and Severe Personality Disorder) and the option of specifying one or more prominent trait domain qualifiers (Negative Affectivity, Detachment, Disinhibition, Dissociality, and Anankastia). Additionally, the practitioner is also allowed to specify a Borderline Pattern qualifier. This article presents how the ICD-11 Personality Disorder classification may be applied in clinical practice using five brief cases.

Schema therapy conceptualization of personality functioning and traits in ICD-11 and DSM-5.

Purpose Of Review: Schema therapy conceptualizes personality disorders in terms of modes and underlying schemas. This article reviews the literature on schema therapy conceptualization of personality disorder functioning and traits, and proposes how these findings apply to novel personality disorder classification in ICD-11 and the DSM-5 Alternative Model of Personality Disorders (AMPD).

Recent Findings: Maladaptive schemas and modes are generally associated with personality dysfunction and traits in conceptually coherent ways.

Criterion A of the AMPD in HiTOP.

The categorical model of personality disorder classification in the American Psychiatric Association's (5th ed. []; American Psychiatric Association, 2013 ) is highly and fundamentally problematic. Proposed for 5 and provided within Section III (for Emerging Measures and Models) was the Alternative Model of Personality Disorder (AMPD) classification, consisting of Criterion A (self-interpersonal deficits) and Criterion B (maladaptive personality traits).

Level of Personality Functioning Scale-Brief Form 2.0: Utility in Capturing Personality Problems in Psychiatric Outpatients and Incarcerated Addicts.

This study examined the utility of the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF 2.0) in measuring features corresponding to self-other impairment of personality functioning as defined in the new general diagnostic guidelines for Personality Disorder in DSM-5 Section III and ICD-11.

Schemas and modes in borderline personality disorder: The mistrustful, shameful, angry, impulsive, and unhappy child.

In this study we investigated how early maladaptive schemas and schema modes uniquely characterize Borderline Personality Disorder (BPD) patients versus comparison groups. BPD patients (n = 101) were systematically matched with personality disordered patients without BPD (n = 101) and healthy controls (n = 101). Differences were investigated using one-way ANOVA and multinomial logistic regression analyses.
