We examined the operationalization of psychopathy through a multi-method framework in a community sample of 250 participants, who were oversampled for psychopathic traits. Psychopathy was operationalized through clinician-rated measures, including the Psychopathy Checklist: Screening Version and the Comprehensive Assessment of Psychopathic Personality (CAPP): Symptom Rating Scale, as well as the Triarchic Psychopathy Measure and the CAPP-Self Report. Using Exploratory Structural Equation Modeling and controlling for self-report and clinical rating method variances, a four-factor model of psychopathy emerged with factors representing Boldness, Disinhibition, Affective, and Interpersonal traits.

The present study explored the utility of a widely used omnibus assessment instrument, the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF), to predict change in functioning during treatment for BPD. Data were obtained from a randomized clinical trial into the effectiveness of 2-year evidence-based treatment for BPD (dialectical behavior therapy or schema therapy) among 130 participants diagnosed with BPD.

The Compulsivity (CMP) scale introduced with the MMPI-3 assesses compulsive behaviors. To address the question of compulsivity's placement within a hierarchical psychopathology structure, the current study examined the degree to which CMP scores share variance with internalizing, fear, and thought dysfunction factors using confirmatory factor analyses.

The goal of this investigation was therefore to examine the validity of these MMPI-3 scales in the measurement of the externalizing spectrum. A community sample ( = 206) with high levels of externalizing psychopathology and a university sample ( = 645) were used.

Background: Many original studies have evaluated the validity and utility of the Alternative Model for Personality Disorders (AMPD) in Iran. However, the present review is a unique attempt to summarize the data in a critical framework to cover gaps in the AMPD research and determine future directions. The review aimed to explore the psychometric evidence for the AMPD, including reliability (alpha coefficient) and validity (construct, convergent, criterion, and incremental types) data in Iran.

Study participants were randomly assigned to either the underreporting ( = 100) or standard instruction ( = 224) conditions. All participants first completed a series of extratest measures under standard instruction prior to the MPQ administration.
View Article and Find Full Text PDFPsychopathic personality disorder (PPD) is a widely recognized disorder that has been associated with high levels of dysfunction across clinical, forensic, occupational, and social settings. The psychopathy construct displays robust connections to social and interpersonal dysfunction; however, research investigating these associations thus far largely relies on total or domain-level scores. This study aimed to employ a higher degree of abstraction to examine associations between psychopathy symptoms and various interpersonal outcomes at different levels of the psychopathy trait hierarchy.

Objective: Research so far has investigated the bivariate relationships between psychopathic traits, romantic attachment, and emotion dysregulation. However, no research thus far has examined these concepts in their interrelatedness. The aim of the present study was therefore to shed light on the possible linking mechanisms among these concepts, examining the mediating role of emotion dysregulation in the psychopathic traits-romantic attachment link.

Proliferation and variability of psychological measures are part of the natural workings of the scientific process. They contribute to theory development, transparency, replicability, and validity, and restricting proliferation might hinder progress in the psychological sciences.

To this end, a series of hierarchical regression analyses was conducted in which the 10 SII-PDs and the five AMPD trait domains served as the predictor variables and five areas of clinical dysfunction as the criterion variables. Two models for each criterion were tested.

The current study aimed to examine the criterion and incremental validity of the IMP scale. A university student sample ( = 1,440) and a community sample oversampled for externalizing tendencies ( = 231) were used for this purpose, and IMP scores were compared to scores on various well-validated criterion measures of impulsivity and externalizing psychopathology.

We investigated psychopathy from the neurobiological perspective of reinforcement sensitivity theory (RST). In contrast to previous semantically derived self-report scales, we operationalised RST systems neurally with evoked electroencephalography (EEG). Participants were from a community sample weighted towards externalising psychopathology.

Study 1 describes the development of the MMPI-3 PD syndrome scales in three separate samples of community participants (n = 1,591), university students (n = 1,660), and outpatient mental health patients (n = 1,537). The authors independently evaluated each of the 72 new MMPI-3 items and rated them for appropriateness for scale inclusion and used various statistical procedures for final item selection.

The present study aimed to validate ICD-11 PD trait domains using a multimethod design in a community mental health sample (n = 336).

The most recent version, the MMPI-3, should be in a good position to continue this tradition, and the aim of the current research was to evaluate its scales for this purpose. We examined, on the basis of previous research, how well conceptually relevant MMPI-3 scales mapped onto dominant contemporary psychopathy models: the traditional three-factor model and triarchic psychopathy model.

Our study compared the impact of administering Symptom Validity Tests (SVTs) and Performance Validity Tests (PVTs) in in-person versus remote formats and assessed different approaches to combining validity test results. Using the MMPI-2-RF, IOP-29, IOP-M, and FIT, we assessed 164 adults, with half instructed to feign mild traumatic brain injury (mTBI) and half to respond honestly. Within each subgroup, half completed the tests in person, and the other half completed them online via videoconferencing.

A community sample (N = 516; 72% female) was administered the PID-5, which can operationalize both the DSM-5 and ICD-11 systems. The factor structures of both systems were tested using exploratory structural equation modeling (ESEM).

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.

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.
Current guidelines for conducting symptom validity assessments require that professionals administer multiple symptom validity tests (SVTs) and that the SVTs selected for their evaluations provide nonredundant information. However, not many SVTs are currently available, and most of them rely on the same, (in)frequency-based, feigning detection strategy. In this context, the Inventory of Problems (IOP-29) could be a valuable addition to the assessor's toolbox because of its brevity (29 items) and its different approach to assessing the credibility of presented symptoms.
