This reply to Conway et al. (2025) illustrates how points of contention in the evaluation of mindreading (or theory of mind) measures can arise from the use of divergent validity concepts. The construct validity model used in Wendt et al.’s (2024) empirical study contrasts with the perspective implicit in Conway and colleagues’ commentary, which is...
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...
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 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...
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...

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...

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...
Understanding language is crucial to psychological research, as it is the basis foralmost all psychological measurements. Following previous works, we conducted a pre-registered replication study, analyzing 876 unique terms generated by 187 participants in a free response format. These terms were rated on social desirability, observability, importa...
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...

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...
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 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...
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...

According to control mastery theory, patients in psychotherapy try to master their problems by disconfirming their pathogenic beliefs. This can be done by testing the therapist. So far, there is hardly any evidence on what concrete interventions or statements of therapists are specifically helpful in passing those tests. In our study, we analyzed t...

Initial results indicated that the PDS-ICD-11 measures a u...

Zusammenfassung
Das Mentalisierungskonzept ist sowohl in der Praxis als auch der Wissenschaft breit rezipiert worden, u. a. wegen seiner hohen klinisch-therapeutischen Relevanz. Um dieses Konzept der empirisch-quantifizierenden Forschung zugänglich zu machen ist u. a. der Reflective Functioning Questionnaire mit 8 Items (RFQ-8) entwickelt worden, d...
Researchers are increasingly interested in the affect dynamics of individuals for describing and explaining personality and psychopathology. Recently, the incremental validity of more complex indicators of affect dynamics (IADs; e.g. autoregression) has been called into question (Dejonckheere et al., 2019), with evidence accumulating that these mig...

Interpersonal problems are key transdiagnostic constructs in psychopathology. In the past, investigators have neglected the importance of operationalizing interpersonal problems according to their latent structure by using divergent representations of the construct: (a) computing scores for severity, agency, and communion (“dimensional approach”),...
