Five-factor personality traits and functional somatic disorder: A systematic review and meta-analysis.

Introduction: Functional Somatic Disorders (FSD) is an umbrella term for various conditions characterized by persistent and troublesome physical symptoms, that are not better explained by other psychiatric or somatic conditions. Personality traits may play a crucial role in FSD, but the link is not fully understood. This study presents a systematic review and meta-analysis examines the relationship between the Five-Factor Model (FFM) of personality traits and FSD.

Self-Reported Personality Disorder Severity in Peruvian Adolescents: Structure, Validity, and Tentative Cutoffs.

Personality disorder (PD) is particularly common in adolescents, which underscores the significance of early screening, diagnosis, and intervention. To date, the definition of PD in the new has not yet been investigated in adolescents. This study therefore aimed to investigate the unidimensionality and criterion validity of self-reported PD features in Peruvian adolescents using the Personality Disorder Severity ICD-11 (PDS-ICD-11) scale.

Internal consistency of measures for ICD-11 personality disorder severity and traits: A systematic review and meta-analysis.

A number of measures and scales have been developed for the ICD-11 personality disorder (PD) diagnosis, including severity and trait dimensions. The present systematic review and meta-analysis sought to evaluate the internal consistency of these measures across different populations and cultures. A systematic search was conducted across four databases where relevant studies were subjected to explicit eligibility criteria resulting in 49 included studies and 370 effect sizes.

Narcissistic personality disorder in the ICD-11: Severity and trait profiles of grandiosity and vulnerability.

Modern diagnostic and classification frameworks such as the ICD-11 and DSM-5-AMPD have adopted a dimensional approach to diagnosing personality disorder using a dual "severity" and "trait" model. As narcissistic personality has historically struggled to be adequately captured in dominant diagnostic systems, this study investigated the utility of the new ICD-11 framework in capturing diverse narcissistic expressions. Participants were mental health clinicians (N = 180, 67% female, age = 38.

Schema therapy versus treatment as usual for outpatients with difficult-to-treat depression: study protocol for a parallel group randomized clinical trial (DEPRE-ST).

Background: About one third of patients with depression are in a condition that can be termed as "difficult-to-treat". Some evidence suggests that difficult-to-treat depression is associated with a higher frequency of childhood trauma and comorbid personality disorders or accentuated features. However, the condition is understudied, and the effects of psychotherapy for difficult-to-treat depression are currently uncertain.

Transdiagnostic psychopathology in the light of robust single-trial event-related potentials.

Recent evidence indicates that event-related potentials (ERPs) as measured on the electroencephalogram (EEG) are more closely related to transdiagnostic, dimensional measures of psychopathology (TDP) than to diagnostic categories. A comprehensive examination of correlations between well-studied ERPs and measures of TDP is called for. In this study, we recruited 50 patients with emotional disorders undergoing 14 weeks of transdiagnostic group psychotherapy as well as 37 healthy comparison subjects (HC) matched in age and sex.

Affectivity in danish patients with emotional disorders: assessing the validity of the Positive and Negative Affect Schedule (PANAS).

Background: The Positive and Negative Affect Schedule (PANAS) was designed to measure trait positive affect (PA) and trait negative affect (NA).

Methods: The Danish PANAS was administered to outpatients with depression and anxiety disorders. Internal consistency was assessed using Cronbach's alpha and McDonald's omega and factorial structure was evaluated using confirmatory factor analysis (CFA).

Utility of the Work and Social Adjustment Scale (WSAS) in predicting long-term sick-leave in Danish patients with emotional disorders.

Background: The Work and Social Adjustment Scale (WSAS) is a self-administered measure designed to assess the level of inability to function socially as a consequence of a defined problem or disorder.

Methods: A total of 230 patients with emotional disorders completed the Danish translation of the WSAS, measures of anxiety and depression, the Level of Personality Functioning Brief Form, the Personality Inventory for DSM-5 Short Form, and the World Health Organization Five-Item Well-Being Index (WHO-5). We conducted a confirmatory factor analysis of the previously suggested factor structure of the instrument.

Clinician-rated ICD-11 trait domains and personality disorder types.

The (11th edition; ) has adopted a classification of personality disorders (PDs) that abolishes the established (10th edition; ) PD types in favor of global severity and stylistic trait domain specifiers. The goal of the current study was to describe the empirical relationship between traditional PD types and the trait domains, which is anticipated to inform and guide clinicians in this profound transition. A total of 246 patients were rated by their clinicians.

Development and psychometric evaluation of the Personality Disorder Severity ICD-11 (PDS-ICD-11) Clinician-Rating Form.

No clinician-rating tool has formally been developed to assess the ICD-11 model of personality disorder (PD) severity. We therefore developed and evaluated the 14-item personality disorder Severity ICD-11 (PDS-ICD-11) Clinician-Rating Form. A combined sample of 195 patients was rated by mental health professionals or clinical research assistants in New Zealand using the PDS-ICD-11 Clinician-Rating Form.

ICD-11 personality disorder features in the danish general population: Cut-offs and prevalence rates for severity levels.

Introduction: Prevalence rates and correlates of personality disorders (PD) are relevant to health care policy and planning.

Objectives: To present normative data for self-reported ICD-11 personality disorder (PD) features including tentative cut-off scores and prevalence rates for severity levels along with psychosocial correlates.

Methods: The Personality Disorder Severity ICD-11 (PDS-ICD-11) scale and criterion measures of impairment were administered to a social-demographically stratified sample of Danish citizens (N = 8,941) of which 3,044 delivered complete data.

Co-occurrence of borderline and schizotypal personality disorders: a scoping review.

Background: The historical concept of borderline conditions refers to the pathology on the border between neurosis and psychosis. In the conditions were divided into specific but also somewhat overlapping diagnostic criteria for Borderline Personality Disorder (BPD) and Schizotypal Personality Disorder (SPD). This phenomenological overlap, which results in co-occurrence of the two diagnoses, remains a clinical challenge to this day.

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.

Differential Diagnosis of ICD-11 Personality Disorder and Autism Spectrum Disorder in Adolescents.

The International Classification of Diseases 11th Revision (ICD-11) introduces fundamentally new diagnostic descriptions for personality disorder and autism spectrum disorder. Instead of the traditional categorical taxonomies, both personality disorder and autism spectrum disorder are described as being on a continuum. Accumulating research has pointed out that, in some cases, adolescents with autism spectrum disorder are at risk of being confused with having a personality disorder, which particularly applies to female adolescents.

Trait and symptom change in group cognitive behaviour therapy for anxiety and depression.

Personality traits underlying both anxiety disorders and depression are more malleable than previously presumed. This study examined associations between changes in personality traits (i.e.

Cross-walking personality disorder types to ICD-11 trait domains: An overview of current findings.

The ICD-11 has adopted a classification of Personality Disorders (PD) that abolishes the established categorical PD types in favor of global severity classification with specification of individual trait domains. To facilitate and guide this profound transition, an overview of current research on empirical associations between established PD types and ICD-11 trait domains seems warranted. We identified a total of 9 relevant studies from 2018 to 2022, which were based on both clinical and community samples from U.

Evaluation of a 36-item measure of ICD-11 and DSM-5 personality disorder trait domains and facets in Russian inpatients.

The have introduced a new dimensional approach to personality disorder (PD) classification that relies on the global level of PD severity and individual expressions of personality dysfunction in terms of specified trait domains (i.e., negative affectivity, detachment, antagonism, disinhibition, anankastia, and psychoticism).

The Relationship between Traumatic Life Events and Polysubstance Use: Examining the Mediating Role of DSM-5 Level of Personality Functioning and Maladaptive Personality Traits.

The experience of traumatic events in childhood is an important risk factor for the initiation and continuation of polysubstance use. This study aimed to examine the mediating role of DSM-5 level of personality functioning and maladaptive personality traits in the relationship between traumatic life events and polysubstance use. We used a mixed sample (=290; = 40; = 12.

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.

Connecting DSM-5 and ICD-11 trait domains with schema therapy and dialectical behavior therapy constructs.

The DSM-5 Section III alternative model of personality disorder (AMPD) and the International Classification of Diseases - 11th Edition's (ICD-11) personality disorder classification allow clinicians to identify individual trait domains in which people score highly. However, how these domains relate to constructs associated with efficacious treatment approaches is unclear. The current study aimed to determine whether constructs from two evidence-based treatments (schema therapy [ST] and dialectical behavior therapy [DBT]) were associated with maladaptive personality traits in a way consistent with underlying theories.

Examining the construct validity of the Personality Assessment Questionnaire for ICD-11 (PAQ-11) personality trait domains in a community sample.

The ICD-11 has a new diagnostic system for personality disorder, which includes five optional trait specifiers to characterize the diagnosed pathology. The current study evaluated the internal structure and construct validity of the Personality Assessment Questionnaire for ICD-11 (PAQ-11) personality trait domains in a US population-representative community sample. An exploratory factor analysis revealed the support for a four-factor model underlying the 17 PAQ-11 items, reflecting four of the five ICD-11 trait domains (Negative Affectivity, Detachment, Disinhibition and Anankastia).

Organization of Clinician-Rated Personality Disorder Types According to Severity of Personality Dysfunction.

The model of personality disorders (PD) allows clinicians to classify personality dysfunction according to four levels of severity. This approach is partially inspired by Kernberg's levels of personality organization, in which various PD types are organized according to their level of severity. This study sought to investigate whether the established PD categories can be organized according to the four levels of PD severity, and to what extent this organization aligns with Kernberg's four levels of personality organization.
