Introduction: Dimensional models of personality disorders (PD) in the DSM-5 and ICD-11 share a focus on impairments in self and interpersonal functioning to represent the general features and severity of PD. This new perspective has led to the development of numerous measures for assessing individual differences in PD severity. While this improves...

The current classification systems for mental disorders, DSM-5 and ICD-11, have been criticized for their lack of structural validity and their arbitrary categorical distinction between mental disorders and mental health. In response, the Hierarchical Taxonomy of Psychopathology (HiTOP) consortium has emerged to propose an alternative model for con...

Aktuelle Klassifikationssysteme für psychische Störungen wie das DSM-5 und ICD-11 stehen zunehmend in der Kritik, die Komplexität psychischer Probleme nicht adäquat abzubilden. Ungünstig sind insbesondere die implizite Orientierung am medizinischen Krankheitsmodell, die mangelnde strukturelle Validität sowie die kategoriale Abgrenzung zu psychische...

The International Classification of Diseases (ICD-11) features a new classification of personality disorders (PD), focusing on the severity of PD. Although there are numerous self-report measures that assess PD severity, to date only the Personality Disorder Severity-ICD-11 (PDS-ICD-11) is based on ICD-11's operationalization of PD. Initial results...

Dimensional models are becoming increasingly important in the classification of personality disorders. A central concept of this paradigm shift is the notion of a continuum of personality functioning ranging from a healthy to an extremely disturbed personality. In the Alternative Model for Personality Disorders in DSM-5 Section III, this concept co...

Patterns of correlations among judgments of targets on different items are the basis for common psychometric procedures such as factor analysis and network modeling. The outcomes of such analyses may shape the images (i.e., theories) that we as scientists have of the phenomena that we study. However, key conceptual issues tend to be overlooked in t...

While personality research has repeatedly shown that self-, meta- and other-ratings of personality are correlated to a considerable degree, relatively little is known about how item features determine agreement between different perspectives, especially beyond observability and social desirability and at the level of personality nuances. The presen...

The Alternative DSM-5 Model for Personality Disorders (AMPD) and ICD-11 adopt a dimensional approach to personality disorders, defining them in terms of impairments in self-related (identity, self-direction) and interpersonal (empathy, intimacy) personality functions. This study examined the clinical utility of a clinician-rated global evaluation o...

Ambulatory Assessment (AA) studies have proliferated in mental health science, promising unparalleled insights into the dynamic nature of mental health. The high methodological heterogeneity of AA studies calls for the harmonization of approaches and the establishment of research standards. This expert consensus provides an overview of best-practic...

Conceptualization and assessment of psychopathology is shifting away from discrete diagnoses to basic dimensions and processes. However, this transition is mostly supported by cross-sectional research, focusing on between-persons differences despite psychopathological processes being conceptualized at the within-persons level. This lack of within-p...

In this registered report ( N = 423), we investigated in a competitive intergroup context to what extent the perception of targets scoring high in grandiose narcissism varies depending on whether they belong to one’s own group or to an opposing outgroup. In a laboratory study, members of newly formed groups had direct contact with another group and...

Both Kernberg's model of personality organization and the alternative model for personality disorders (AMPD) in the Diagnostic and Statistical Manual of Mental Disorders-5th edition provide a multidimensional framework for assessing personality pathology, while having a dual focus on general and specific personality pathology. The present study was...

Introduction: This pragmatic study evaluates the long-term effectiveness of two forms of psychoanalytically oriented therapy, Psychodynamic Psychotherapy (PP) and Analytical Psychotherapy (AP), in routine care in Germany. Methods: Four hundred and twenty-eight patients diagnosed with various DSM-IV mental disorders were treated with PP or AP and pr...

Research in psychology can have various foci, ranging from the psychological dynamics of single individuals to the generalization across individuals, often termed idiographics and nomothetics, respectively. However, terminological ambiguities have limited communication clarity about idiographics and nomothetics. Importantly, whether studies are sui...

Ambulatory assessment is widely popular in research settings for its ability to assess real world functioning in context. It can be useful for estimating an individual’s typical level of a behavior (individual mean), how (un)stable that behavior is (individual standard deviation), how behaviors associate with others or specific contexts (within-per...

Objective: With meta-analytically estimated rates of about 25%, dropout in psychotherapies is a major concern forindividuals, clinicians, and the healthcare system at large. To be able to counteract dropout in psychotherapy, accurate insights about its predictors are needed. Method: We compared logistic regression models with two machine learning...

The COVID-19 pandemic, marked by the threat of infection, severe illness, and stringent public health measures, has significantly transformed the lives of individuals. This challenging scenario provides a valuable context for examining the potential impact of such disruption on maladaptive personality traits—dispositions that can lead to distress,...

The Hierarchical Taxonomy of Psychopathology (HiTOP) arranges phenotypes of mental disorders based on empirical covariation, ranging from narrowly defined symptoms to higher-order spectra of psychopathology. Since the introduction of personality functioning (PF) in DSM-5 and ICD-11, several studies have identified PF as a predictor of transdiagnost...

People make countless decisions every day. We explored the self-regulatory function of decisions and assumed that the very act of making a decision in everyday life enhances people’s mood. We expected that this decision-related mood change would be more pronounced for intuitive decisions than for analytical ones. The ease of making a decision and t...

Introduction: The alternative model for personality disorders (AMPD) of the Diagnostic and Statistical Manual of Mental Disorders - 5th edition (DSM-5) considers impairments in empathy a basic feature of personality disorders (PDs). In contrast, the AMPD pathological personality trait model and the categorical DSM-5 Section II PD model associate d...

The classification of personality disorder (PD) is undergoing a paradigm shift in which categorically defined specific PDs are being replaced by dimensionally defined maladaptive trait domains. To bridge the classificatory approaches, this study attempts to use items from the categorical PD model in DSM-IV to measure the maladaptive trait domains d...

Mindreading ability—also referred to as cognitive empathy or mentalizing—is typically conceptualized as a relatively stable dimension of individual differences in the ability to make accurate inferences about the mental states of others. This construct is primarily assessed using self-report questionnaires and task-based performance measures. Howev...

Conceptual work integrating constructs from mainstream personality research (especially socalled “dark” traits) and clinical psychopathology research has been limited. Herein, we propose all socially and/or ethically aversive traits as “flavored” manifestation of the D-Factor of Personality (D). We argue that the D-framework provides the commonalit...

Introduction The ICD-11 and DSM-5 are the leading systems for the classification of mental disorders, and their relevance for clinical work and research, as well as their impact for policy making and legal questions, has increased considerably. In recent years, other frameworks have been proposed to supplement or even replace the ICD and the DSM, r...

Background: There is an increasing interest in conceptualizing psychopathology in terms of transdiagnostic dimensions and processes. These can be organized hierarchically, for instance, aggression and harmful substance use are specific manifestations of externalizing psychopathology. However, most of this work is cross-sectional and focuses on indi...

The Self and Interpersonal Functioning Scale (SIFS) is a 24-item self-report questionnaire assessing personality functioning according to the alternative DSM-5 model for personality disorders. We evaluated the German SIFS version in a total sample of 886 participants from Germany and Switzerland. Its factor structure was investigated with confirmat...

Research utility and clinical translation of the model require measures that are keyed to the model. The Measures Development Workgroup of HiTOP is developing both questionnaire and interview methods that (...

People often attribute success to themselves and failure to others. Past research indicates that this tendency toward self-serving attributions is pronounced among individuals high in trait narcissism. The aim of this registered report was to re-visit the link between narcissism and self-serving attributions by studying attributions in a group cont...

The factor structure of Personality Disorder (PD) criteria has long been debated, but due to previous heterogenous findings, a common structure to represent covariation among DSM-IV/DSM-5 Section II PD criteria remains an open question. This study integrated a total of N = 30,545 PD assessments from 25 samples to conduct an individual participant m...
