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…

The objective of this study was to create a psychometrically valid and reliable toxic leadership scale (TLS) for use in higher education workplace environments. The TLS was administered to a sample of 482 faculty members employed by three public universities in Jordan. Another aim of the study was to determine the level of toxic leadership based…

Universal screening for behavioral/mental health risk is a critical component of multitiered systems of support, allowing for early identification of students in need of prevention and/or intervention services. The Student Risk Screening Scale (SRSS; Drummond, 1994) is one commonly used universal screening tool intended to measure externalizing…

Objective: Cyber bullying represents a new and alarming form of bullying that potentially leads to serious and long-lasting consequences for young people; yet, there is a dearth of research on the assessment of cyberbullying behaviors among emerging adults. Thus, this study aims to close this gap by assessing the development and validation of the…

The validity of the Multidimensional School Anger Inventory (MSAI) was examined with adolescents from 5 Pacific Rim countries (N = 3,181 adolescents; age, M = 14.8 years; 52% females). Confirmatory factor analyses examined configural invariance for the MSAI's anger experience, hostility, destructive expression, and anger coping subscales. The…

The Authoritative School Climate Survey was designed to provide schools with a brief assessment of 2 key characteristics of school climate--disciplinary structure and student support--that are hypothesized to influence 2 important school climate outcomes--student engagement and prevalence of teasing and bullying in school. The factor structure of…

Background: Different dimensions of oppositional defiant disorder (ODD) have been found as valid predictors of further mental health problems and antisocial behaviors in youth. The present study aimed at testing the construct, concurrent, and predictive validity of ODD dimensions derived from parent- and self-report measures. Method: Confirmatory…

This study continues previous work documenting the structure of violence perpetrated by males against their female intimate partners. It assesses the construct validity of a measurement model depicting associations among eight subtypes of perpetration: moderate physical violence, severe physical violence, forced or coerced sexual violence, sexual…

We aimed to analyze the internal consistency and construct validity of the Spanish version of the Index of Spouse Abuse (ISA) in a representative sample of 8,995 women attending general practice in Spain in 2006-2007. The factor structure analysis shows that the ISA measures four intimate partner violence (IPV) dimensions: emotional, physical, and…

Although the construct of psychopathy is frequently construed as a unitary syndrome, the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) and its revision, the PPI-R (Lilienfeld & Widows, 2005), are composed of 2 scales, termed Fearless Dominance (FD) and Self-Centered Impulsivity (SCI), which appear to reflect orthogonal…

The authors examined the psychometric properties, factor structure, and construct validity of the Dissociative Experiences Scale (DES) in a large offender sample (N = 1,515). Although the DES is widely used with community and clinical samples, minimal work has examined offender samples. Participants were administered self-report and interview…

Scant research has examined the validity of instruments that permit observer ratings of psychopathy. Using a nonclinical (undergraduate) sample, the authors examined the associations between both self- and observer ratings on a psychopathy prototype (Psychopathy Q-Sort, PQS) and widely used measures of psychopathy, antisocial behavior, and…

A limited number of studies currently exist focusing on comorbid psychopathology of children with autism spectrum disorders (ASDs). Due to the heterogeneity of ASD symptoms, communication deficits, and impairments in intellectual functioning, assessing symptoms of psychopathology is complicated. The "Autism Spectrum Disorders-Comorbidity for…

The aim of this research is to develop the Mobbing Scale and examine its validity and reliability. The sample of the study consisted of 515 persons from Sakarya and Bursa. In this study, construct validity, internal consistency, test-retest reliability, and item analysis of the scale were examined. As a result of factor analysis for construct…

This study examined the convergent validity of the parent and teacher versions of the Early Childhood Behavior Problem Screening Scale (ECBPSS) with the Child Behavior Checklist (CBCL) and the Caregiver-Teacher Report Form (C-TRF), respectively. Data were collected on a sample of preschool and kindergarten students (n = 149) from two medium-sized…
