Article
The aim of the current study was to further examine the psychometric properties of the Expanded Levenson Self-Report Psychopathy Scale (E-LSRP; Christian & Sellbom, 2016). Specifically, its reliability, internal structure, and convergent and discriminant validity were evaluated using university ( N = 367) and community samples ( N = 205) from Aotea...
Article
Objective: The general understanding of disorders related to chronic somatic symptoms (e.g., somatic symptom disorder, functional somatic syndromes) is limited due to current categorical conceptualizations in traditional taxonomies. To improve clinical utility and validity, the Hierarchical Taxonomy of Psychopathology (HiTOP) offers an empirically...
Preprint
The 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 indicated that the PDS-ICD-11 measures a u...

The purpose of the current study was to evaluate the validity of scores on the Eating Concerns (EAT) scale on the recently released Minnesota Multiphasic Personality Inventory-3 (MMPI-3), which aims to assess for problematic eating behaviours. It was hypothesised that the EAT scale scores would be correlated with binge eating, purging, restrictive...
Article
Full-text available
In psychological injury and related forensic evaluations, two types of tests are commonly used to assess Negative Response Bias (NRB): Symptom Validity Tests (SVTs) and Performance Validity Tests (PVTs). SVTs assess the credibility of self-reported symptoms, whereas PVTs assess the credibility of observed performance on cognitive tasks. Compared to...
Article
The recently released Minnesota Multiphasic Personality Inventory-3 (MMPI-3) includes a revised set of Validity Scales on which there is currently limited validity and clinical utility evidence for the detection of overreporting. The present study evaluated the MMPI-3 Validity Scales in the identification of such response bias. An analogue simulati...
Article
The current study aimed to examine the associations between Minnesota Multiphasic Personality Inventory-3 (MMPI-3) scales and the dimensional personality traits contained within the ICD-11 Personality Disorder diagnosis and DSM-5 Alternative Model for Personality Disorders (AMPD) models. The sample consisted of 489 undergraduate students, with dime...
Article
Full-text available
Although psychopathic personality has been described as a syndrome comprising three or four distinct personality domains, there is still no firm consensus regarding which traits constitute the core features of psychopathy. The present study conducted a network analysis to examine the network structure of psychopathy as operationalized by the Levens...
Article
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...
Article
The MCMI-IV and MACI-II are the most recent iterations of the primary Millon clinical inventories and have become well-established instruments over the course of multiple editions. The MCMI, in particular in its prior editions, and to a lesser extent, the original MACI, have joined the canon of commonly-used psychological instruments in several for...
Article
Full-text available
A prevailing view among researchers and mental health clinicians is that symptoms of antisocial personality disorder (ASPD)/psychopathy decrease as affected individuals reach middle age. In the current investigation, informants were surveyed about the behavior of individuals who they believed showed traits of ASPD/psychopathy and were over the age...
Chapter
Psychopathy is a contentious construct with respect to both theory and operationalization. A number of myths, misconceptions, and fallacies regarding the assessment of psychopathy hinder scientific progress and impede this construct’s applied consideration across settings and contexts. We review these widespread erroneous ideas with an eye to guidi...
Chapter
This chapter introduces the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) and provides considerations for its use in forensic psychological evaluations. We start with a brief historical overview of the MMPI instruments, culminating in the development of the MMPI-3. We describe the 52 scales of the test and general psychometric properties,...

Article
Full-text available
Like socio-economic status and cognitive abilities, personality traits predict important life outcomes. Traits that reflect unusually low or high approach motivations, such as low extraversion and high disinhibition, are linked to various forms of mental disorder. Similarly, the dopamine system is theoretically linked to approach motivation traits...
Article
Psychopathic personality disorder (PPD) is a widely researched construct characterized by severe dysfunction in affective, interpersonal and behavioral domains. Inconsistencies across different theoretical formulations and operationalizations have major implications for research and practice. Two separate personality-based perspectives of psychopat...

Article
The Expanded–Levenson Self-Report Psychopathy Scale (E-LSRP) was developed by Christian and Sellbom to improve on the psychometric properties of scores on the Levenson Self-Report Psychopathy Scale. The current study investigated the construct validity of scores on the E-LSRP in 393 male inmates. Results provided support for the reliability and con...
Article
The term dissociation is often used to refer to a diverse range of psychological symptoms, including perceptual impairments, emotional detachment, and memory fragmentation. In the present study, we examined whether there was a relation between participants’ self-reports of dissociative experiences and their memory performance in the Deese-Roediger-...
Article
Objective The current study examined associations between Minnesota Multiphasic Personality Inventory-3 (MMPI-3) scales and self-reported DSM-5 Section II personality disorder (PD) symptoms. A priori hypotheses were generated for which MMPI-3 scales would be most highly associated with each PD. Methods We used a large sample (n = 489) of universit...
Article
A major goal in the development of the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF), and subsequently, the Minnesota Multiphasic Personality Inventory-3 (MMPI-3) was linking the instrument to contemporary models of psychopathology. The present study evaluated whether the higher order structure of MMPI-3 scales, and in...

We therefore set out to develop and evaluate the 14-item Personality Disorder Severity ICD-11 (PDS-ICD-11) scale. Method A representative U.S. community sample (N = 428; 50.9% women) and a New Zealand mental health sample (N = 87;...
Article
The Comprehensive Assessment of Psychopathic Personality-Self-Report (CAPP-SR) is a recent operationalization of the CAPP model, which conceptualizes psychopathy in terms of 33 symptoms that can be thematically organized according to six theoretical domains. The current study examined the higher order factor structure of the CAPP-SR symptom scales...
Article
The concept of ‘successful’ psychopathy has intrigued the field, yet relatively little actual science exists to understand what makes those high in psychopathic traits more or less successful, or even what constitutes ‘success.’ In the current study, we examined the validity of the moderated expression hypothesis, including an elaborated version th...
Article
The current study examined the differentiation of borderline (BPD) and antisocial personality disorders (ASPD) in forensic settings, with particular emphasis on the utility of the MMPI-2-RF in differential diagnosis. This study examined these constructs across correctional and forensic psychiatric samples from the U.S. and the Netherlands using var...
Article
The triarchic model is an increasingly influential multidimensional model of psychopathy that focuses on three distinct phenotypic domains of boldness, meanness, and disinhibition. Although originally operationalized through the Triarchic Psychopathy Measure (TriPM), the triarchic model has also been operationalized through items of existing psycho...
Article
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...
Chapter
Measurement is one of the fundamental steps to explore connections of components within a construct and between the construct and external phenomena. Measurement and psychometrics are important in clinical psychology to evaluate merits of psychological tests. This article introduces fundamental concepts in measurement and discusses various essentia...
Chapter
Surveys of clinical psychologists exploring the distribution of their time across the provision of services in their practice reveal that most clinical psychologists devote a considerable amount of time to psychological assessment, and this has held steady over several decades (Archer et al., 2006; Camara et al., 2000; Wright et al., 2017). This wa...
