The alternative model for the classification of personality disorders (PD) in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) Section III comprises 2 major components: impairments in personality functioning (Criterion A) and maladaptive personality traits (Criterion B). In this study, we investigated the latent structure...

Both theories and cutting-edge research highlight the dynamic nature of personality and personality pathology, thereby posing significant challenges for an exclusively between-person, trait-based approach to personality assessment. In a series of three studies, we explored the viability of integrating within-person, dynamic aspects into clinical pe...

A great range of person perception phenomena may be conceptualized in terms of how much perceivers know about the targets, how much they like the targets and how these factors relate to the extent to which target descriptions reflect actual target characteristics and/or evaluative bias. We present a comprehensive empirical analysis of this interpla...

Ambulatory assessment (AA; also known as ecological momentary assessment) has enjoyed enthusiastic implementation in psychological research. The ability to assess thoughts, feelings, behavior, physiology, and context intensively and repeatedly in the moment in an individual's natural ecology affords access to data that can answer exciting questions...

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...

Etiological theories on the development of psychopathology often incorporate adverse childhood experiences (ACE) as an important contributing factor. Recent studies suggest personality functioning (PF; i.e., stability of the self and interpersonal relationships) as an important transdiagnostic construct that could be useful in better understanding...

We tested the predictive validity of personality disorder (PD) indicators at different levels of aggregation, ranging from general PD severity to PD syndrome scales to individual PD criteria. We compared the predictive validity of models on these levels based on interview data on all 78 DSM-IV PD criteria, by using 19 outcome scales in three differ...

The current study examined whether personality domains have nonmonotonic relationships with functional outcomes, specifically in relation to quality of life and impairment. Four samples were utilized, which were drawn from the United States and Germany. Personality trait domains were measured via the IPIP-NEO and PID-5; quality of life (QoL) was me...

Objectives: The current research explored the interplay between intuition, meaning in life, and psychopathology. Specifically, we investigated whether experiential and reflective components of meaning in life are associated with depressive symptoms and personality pathology, whether intuition is related to the experience of meaning, and whether ps...

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...

The expanded version of the Inventory of Depression and Anxiety Symptoms (IDAS-II) is a 99-item self-report measure containing 18 nonoverlapping dimensional scales assessing symptoms of depression, anxiety, and mania. The aim of this study was to develop and validate a German adaptation of the IDAS-II. Participants from a community sample (N = 1,05...

The Interpersonal Sensitivities Circumplex (ISC) assesses individual differences in sensitivities to aversive interpersonal behaviors. In this research (total N = 1,519), we developed and validated a German adaptation of the ISC (ISC-G) and extended the nomological net of interpersonal sensitivity as a construct. Using the structural summary method...

Purpose of Review Individuals with personality disorders are frequently seen in mental health settings. Their symptoms typically reflect a high level of suffering and burden of disease, with potentially harmful societal consequences, including costs related to absenteeism at work, high use of health services, ineffective or harmful parenting, subst...

The Hierarchical Taxonomy of Psychopathology (HiTOP) organizes phenotypes of mental disorder based on empirical covariation, offering a comprehensive organizational framework from narrow symptoms to broader patterns of psychopathology. We argue that established self‐report measures of psychopathology from the pre‐HiTOP era should be systematically...

The LoPF-Q 12–18 (Levels of Personality Functioning Questionnaire) was designed for clinical use and to promote early detection of personality disorder (PD). It is a self-report measure with 97 items to assess personality functioning in adolescents from 12 years up. It operationalizes the dimensional concept of personality disorder (PD) severity us...

Zusammenfassung Mit der 11. Version der International Statistical Classification of Diseases and Related Health Problems (ICD-11) erfolgt ein Paradigmenwechsel in der Diagnostik von Persönlichkeitsstörungen: Deren Klassifikation erfolgt künftig nicht mehr kategorial, sondern dimensional entlang der Schweregrade von Persönlichkeitsbeeinträchtigungen...

Die Annahme klar trennbarer Störungsentitäten in kategorialen Diagnosesystemen wird zunehmend in Frage gestellt. In diesem Beitrag werden Angstproblematiken dimensional betrachtet und in ein hierarchisch organisiertes Modell von Psychopathologie eingebettet. Differenzielle Chronifizierungs- und Schweregrade werden vor dem Hintergrund basaler psychi...

DSM-5’s Level of Personality Functioning Scale (LPFS) was introduced as a dimensional rating of impairments in self- and interpersonal functioning, and the LPFS – Brief Form (LPFS-BF) was the first published corresponding self-report. The updated LPFS-BF 2.0 has been translated into several languages and international research supports many of the...

In their target article, Morey et al. (2022) provide a comprehensive overview of research on Criterion A over the past ten years. Although this overview is undoubtedly informative and helpful, it offers little guidance on both certain weaknesses of Criterion A and research gaps and needs. A structural reason for this could be that the scientific fi...

This study examines how often and why suspects who have reported being either guilty or innocent remain silent, confess, or deny accusations in police interview situations. Convicted offenders under current probation or parole in Germany (N = 280) completed a questionnaire about their perceptions of up to six specific police interview situations th...

Background Advancements in the treatment of depression are pivotal due to high levels of non-response and relapse. This study evaluated the role of personality pathology in the treatment of depression by testing whether maladaptive personality traits (1) predict changes in depression over treatment or vice versa , (2) change themselves over treatme...

According to the alternative model for personality disorders (AMPD) of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), a moderate or greater impairment in personality functioning is the essential criterion for a personality disorder diagnosis. Personality functioning is operationalized in the Level of Personality F...

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...

Synthetic metacognition is a heterogeneous construct related to psychotic disorders. One important tool to assess this construct is the Metacognition Assessment Scale - Abbreviated (MAS-A). In this study, we investigated the latent structure as well as the interrater reliability and convergent and incremental validity of the MAS-A in a sample of pa...

Both clinical and personality psychologists are interested in assessing personality change, although they have tended to approach the issue in different ways. In this paper we argue that both sub-fields should focus more on basic issues in the assessment of personality change, and that they would make more progress on this issue together than alone...

The present study examined how personality traits manifest in daily life of older adults and distinguished between the manifestations of experiences and behaviors. We used data from an ambulatory assessment study over 10 days with assessments of trait-related experiences and behaviors obtained from 136 older adults aged between 60 and 91 years (41....

Objective: We examine the trajectories of and the dynamic interplay between cognitive functioning and depressive symptoms in patients with Parkinson's disease (PD) in comparison to healthy controls (HC) from an intraindividual perspective. Method: The DeNoPa study is a single-center, observational, longitudinal study with biennial follow-ups ove...

Introduction: Treatment as usual (TAU) is the most frequently used control group in randomized trials of psychotherapy for depression. Concerns have been raised that the heterogeneity of treatments in TAU leads to biased estimates of psychotherapy efficacy and to an unclear difference between TAU and control groups like waiting list (WL). Objecti...

The Hierarchical Taxonomy of Psychopathology (HiTOP) is a quantitative nosological system that addresses shortcomings of traditional mental disorder diagnoses, including arbitrary boundaries between psychopathology and normality, frequent disorder co-occurrence, substantial heterogeneity within disorders, and diagnostic unreliability over time and...

In their target article, Morey et al. (2022) provide a comprehensive overview of research on Criterion A over the past ten years. Although this overview is undoubtedly informative and helpful, it offers little guidance on both certain weaknesses of Criterion A and research gaps and needs.

Attachment and mentalizing are central concepts in research on the etiology, course, and treatment of depression. The goal of this cross-sectional study was to clarify the unique value of these constructs in characterizing the presence, severity, and chronicity of depression. We examined 50 female inpatients suffering from Major Depressive Disorder...

The Certainty About Mental States Questionnaire (CAMSQ) is a self-report measure of the perceived capacity to understand mental states of the self and others (i.e., mentalizing). In two studies (total N = 1828), we developed the CAMSQ in both English and German as a two-dimensional measure of Self- and Other-Certainty, investigated associations wit...

This handbook is currently in development, with individual articles publishing online in advance of print publication.

This article presents an overview of the current state of knowledge in personality judgment research. We discuss accuracy and bias in personality judgments, including types of inter-rater agreement and elements of criteria used to determine levels of agreement and accuracy. We then address 1) the words and phrases that people use to describe one an...

Zusammenfassung. Die Erfassung von Kindheitserfahrungen stellt einen wichtigen Baustein für Verständnis und Behandlung psychischer Belastungen im Erwachsenenalter dar. Dabei kommt der Erfassung protektiver Kindheitserfahrungen neben etablierten aversiven Erlebnissen eine wachsende Bedeutung zu. Ziel der vorliegenden Studie ist die Erstellung einer...

The current study examined the continuity of personality disorder (PD) diagnoses from Section II to Section III (alternative model for personality disorders [AMPD]) when using structured interviews. We investigated the continuity both in terms of stability of prevalence rates and in terms of convergent validity. A clinical sample of 189 participant...

It is common for people with mental health problems to report feelings of emptiness. However, the association of subjective emptiness with specific disorders and its unique role within dimensional taxonomies of personality pathology is not well understood. The present study assesses the transdiagnostic value of subjective emptiness using a recently...

The Reflective Functioning Questionnaire (RFQ) is an 8-item self-report measure of reflective functioning that is presumed to capture individual differences in hypo- and hypermentalizing. Despite its broad acceptance by the field, we argue that the validity of the measure is not well-established. The current research elaborates on problems of the R...

Objective: Especially for adult patients with anorexia nervosa (AN), treatment response is generally low to moderate. The present study aimed to evaluate the efficacy of cognitive remediation therapy (CRT) as adjunctive treatment for AN regarding clinical and cognitive outcomes. Method: In this randomized controlled superiority trial, 167 adult and...

The 11th version of the International Statistical Classification of Diseases and Related Health Problems (ICD-11) marks a paradigm shift in the diagnosis of personality disorders: In the near future, their classification will no longer be categorical, but dimensional along the severity of personality impairments and optionally regarding the presenc...

Background Attachment insecurity is a prominent risk factor for the development and course of psychiatric and psychosomatic disorders. The Experiences in Close Relationships - Revised (ECR-R) questionnaire is a widely used self-report to assess attachment related anxiety and avoidance. However, its length has the potential to restrict its use in la...

Fragestellung: Inzwischen existieren psychodynamische Selbsteinschätzungsinstrumente zur Erfassung von Struktur und Konflikt als Aspekte der Persönlichkeit. Bezüge zum psychologischen Big-Five-Modell, dem durch einen Paradigmenwechsel in den medizinischen Klassifikationssystemen von Persönlichkeitsstörungen eine größere Bedeutung zukommt, sind bish...

We read the article “Clinimetric Criteria for Patient-Reported Outcome Measures” with great interest. Highlighting certain test characteristics for patient-reported outcome measures (PROMs) that seem to be neglected in the psychometric literature is a commendable endeavor. We share the authors' intention of supporting clinical practice by providing...

Objectives: In different therapeutic approaches, insight is acknowledged as an important part of patient's therapeutic change process. We examined whether the level of insight (1) differs between psychoanalytic (PA), psychodynamic (PD) and cognitive-behavioral therapy (CBT), and (2) predicts long-term symptomatic outcome. Methods: A completer sampl...

Background: Treatment as usual (TAU) is the most frequently used control group in randomised trials of psychotherapy for depression and meta-analyses that summarise these trials. Concerns have been raised over imprecise and biased efficacy estimates because of substantial variability in the treatments provided in TAU. We set out to investigate the...

Personality traits continue to change throughout the lifespan. However, we still know little about when, why, and how personality traits change. In this paper, we review the current state of scientific evidence regarding the nature, sources, and processes of personality trait stability and change. We revisit past disputes over the relative importan...

The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirical-based classification of psychopathology. Detachment is one of the six spectra in the current HiTOP working model. The aim of this study was to develop preliminary scales for the HiTOP Detachment spectrum that can be used in the next phase of developing a comprehensive measure of H...

The current study proposes an adaptation of the PID-5 to assesses maladaptive personal traits in forensic settings. Specifically, we adapted the item set of the PID-5 Faceted Brief Form (PID-5-FBF) to the forensic context and validated the resulting PID-5 Forensic Faceted Brief Form (PID-5-FFBF) using self- and informant-reports of 199 male prisone...

In this article, we describe the collaborative process that is underway to develop measures for the Hierarchical Taxonomy of Psychopathology (HiTOP). The HiTOP model has generated much interest in the psychiatric literature in recent years, but research applications and clinical translation of the model require measures that are specifically keyed...

In two studies (total N = 1828), we developed the CAMSQ in both English and German as a two-dimensional measure of Self- and Other-Certainty, investigated associations wit...

The Alternative DSM-5 Model of Personality Disorders describes the level of personality functioning, defined by impairments in self functioning (self pathology) and problems in interpersonal functioning (interpersonal pathology), as the core feature of all personality disorders. A brief self-report measure to assess the level of personality functio...

Background The Personality Inventory for DSM-5 (PID-5) is the gold-standard self-report tool to assess personality pathology according to five maladaptive trait domains (Criterion B) and may also be used to estimate the severity of personality problems (Criterion A). Previous research incorporating the PID-5 has often been limited by sample selecti...

We established realness as the relatively stable tendency to act on the outside the way one feels on the inside, without regard for proximal personal or social consequences. In nine studies, we showed that realness is a) a core feature of individual differences in authenticity, b) generally adaptive but largely unrelated to agreeableness, c) highly...

This article presents an overview of the current state of knowledge in personality judgment research. We address (1) the words and phrases that people use to describe one another and themselves, (2) research in the “variable-centered” tradition, which investigates judgments of targets by perceivers on single traits, and (3) research investigating j...

Purpose. Suspects are central participants of a police interview and can provide crucial information on the interview interactions with the interviewers. This study examined how the way suspects perceive interviews relates to (a) their reported status of being guilty or innocent and (b) their decision to confess or deny. Methods. A total of 250 con...

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 ge...

Introduction Major depression affects over 300 million people worldwide, but cases are often detected late or remain undetected. This increases the risk of symptom deterioration and chronification. Consequently, there is a high demand for low threshold but clinically sound approaches to depression detection. Recent studies show a great willingness...

While Diagnostic and Statistical Manual of Mental Disorders–Fifth edition (DSM-5) Section III and ICD-11 (International Classification of Diseases 11th–Revision) both allow for dimensional assessment of personality pathology, the models differ in the definition of maladaptive traits. In this study, we pursued the goal of developing a short and reli...

Background Recent preliminary evidence indicates that depression is associated with impaired intuitive information processing. The current study aimed at replicating these findings and to move one step further by exploring whether factors known as triggering intuition (positivity, processing fluency) also affect intuition in patients with depressio...

In this article, we present the hierarchical taxonomy of psychopathology (HiTOP), an evidence-based alternative to the categorical approach to diagnostic classification that has considerable promise for integrative psychotherapy research and practice. We first review issues associated with the categorical approach that may have constrained advances...

In pursuit of a more systematic and comprehensive framework for personality assessment, we introduce procedures for assessing personality traits at the lowest level: nuances. We argue that constructing a personality taxonomy from the bottom up addresses some of the limitations of extant top-down assessment frameworks (e.g., the Big Five), including...

This paper presents a series of pre-registered analyses testing the same theoretically derived hypothesis: If (a) the attitudes that perceivers have toward targets contribute to the variance of judgments on most items, and (b) items’ rated social desirability values align very closely with the extent to which that is the case, then the product of t...

We argue that it is useful to distinguish between three key goals of personality science – description, prediction and explanation – and that attaining them often requires different priorities and methodological approaches. We put forward specific recommendations such as publishing findings with minimum a priori aggregation and exploring the limits...
