The dark core of personality is a recent construct that encompasses the malevolent, antagonistic, and aversive side of human nature that represents the common inner core of dark personality traits. The aim of the present study is to develop a short, multidimensional, and invariant version of the dark core of personality D70 measure. Two samples of…

Recent studies have consistently demonstrated that antisocial behaviors occur in online environments. Although online antisocial behavior has a long history, it appears to have become more widespread in recent years due to the widespread use of online social networks. Although there are established criteria and instruments assessing antisocial…

We aimed to refine the previously proposed antisocial subscale for the Dimensional Clinical Personality Inventory 2 (IDCP-ASPD). The sample involved 628 Brazilian adults between 18 and 81 years old. We administered the revised ASPD subscale (IDCP-ASPD-R), the Affective and Cognitive Measure of Empathy (ACME), the Crime and Analogous Behavior Scale…

The Shedler-Westen Assessment Procedure (SWAP) is a personality assessment instrument designed for use by expert clinical assessors. Critics have raised questions about its psychometrics, most notably its validity across observers and situations, the impact of its fixed score distribution on research findings, and its test-retest reliability. We…

Personality disorder is prevalent among offenders with intellectual disabilities (ID), and it is associated with their risk for violence and recurrent offending behaviour. A new staff-rated instrument, the Personality Disorder Characteristics Checklist (PDCC), designed to screen for ICD-10 dissocial and emotionally unstable personality…

Despite substantial research use, measures of the five-factor model (FFM) are infrequently used in clinical settings due, in part, to issues related to administration time and a reluctance to use self-report instruments. The current study examines the reliability and validity of the Five-Factor Model Score Sheet (FFMSS), which is a 30-item…

The Kentucky Inventory of Mindfulness Skills (KIMS) is a well-validated multidimensional questionnaire measuring dimensions of mindfulness on four scales: Observing, Describing, Act With Awareness, and Accept Without Judgment. Even though the KIMS has been used in several clinical studies no information is available about the psychometric…

A sample of 679 (341 women) emerging adults (M = 18.90 years; SD = 1.11; range = 18.00-22.92) participated in a study on the utility of forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of aggression. We examined the link between these four subtypes of aggression and personality pathology (i.e., psychopathic…

A self-report inventory for the assessment of mindfulness skills was developed, and its psychometric characteristics and relationships with other constructs were examined. Participants included three samples of undergraduate students and a sample of outpatients with borderline personality disorder. Based on discussions of mindfulness in the…

The authors evaluated self-report instruments currently being used to assess children and adolescents with psychopathic personality traits with respect to their reliability, validity, and research utility. Comprehensive searches across multiple computerized bibliographic databases were conducted and supplemented with manual searches. A total of 30…

This study evaluated the structural reliability, construct-related validity, and cultural validity generalization of the Hare Psychopathy Checklist: Screening Version (PCL:SV) in a sample of more than 560 male and female Swedish forensic psychiatric treatment patients, forensic evaluation patients, and criminal offenders.

Issues surrounding accurate assessment of depression in children have received much attention. However, the stability of scores from depression measures has generally been estimated using only classical test score theory, rather than the more powerful generalizability theory. The dependability of scores from the Children's Depression Inventory…

A new assessment scheme--the Short-Term Assessment of Risk and Treatability (START)-- presents a workable method for assessing risks to self and others encountered in mentally and personality disordered clients. This study aimed to demonstrate (a) prevalence and severity of risk behaviors measured by the START, (b) psychometric properties of…
